Various scenarios may require sending email messages or other types of notifications to users as part of the process flow. For example, certain types of exceptions that cannot be handled automatically may require manual intervention. For example, a BPEL process can use the notification service to alert users by voice, IM, SMS, or email.
In a previous article (http://technology.amis.nl/blog/6019/configure-soa-suite-11g-for-sending-email-notifications-with-google-mail) I described recently how the fairly new SOA Suite 11g can use GMail or other public Email servers to send notifications, for example from BPEL processes or the Human Workflow Service. The SOA Suite 11g works with the User Messaging Service (UMS) to perform that feat and the essence of said article is to configure the email driver in UMS to use GMail – or any other email server for that matter.
This article looks at one of the other communication channels available in UMS, and also available to BPEL processes: Instant Messaging or Chat. After configuring the UMS XMPP driver in the Enterprise Manager console, the Chat channel is available to any BPEL process. We will discuss how to configure – and with which More >

SPORTSAFE UK – IRIS
SportsafeUK supply, install and service sports equipment nationally. Their on-site services are conducted by over 40 engineers, who used an Excel-based system and emailed daily service reports. This slow, inconsistent process was inaccurate, costly and impacting other business functions.
ECS designed and implemented IRIS; a bespoke, fully integrated software solution, running on tablets. IRIS communicates seamlessly with two internal systems and enables managers to monitor and control the work, with completed reports automatically distributed.
ECS’s approach in standardising the process reduced the time taken to complete a service report from over 2 days to within 2 hours. It is now far simpler to train new engineers; paper records have been significantly reduced and SportsafeUK have made dramatic savings. The IRIS system has improved their customer experience and the entire business process has become more efficient – with quicker quote generation and faster follow-up on sales leads.
What they said
I have had the pleasure of working with the ECS Team throughout the development of IRIS. At over 25,000 visits per year across the whole country…the way the tablet creates the report for the customer to see whilst our team is still on-site has received great feedback from our 120 councils in the UK.
Our internal processes have sped up to a point where customers receive their quote and report the same day as the inspection…the report feedback direct from the customers is very positive.
The company is now looking at IRIS V2; this will take the system further forward and increase productivity across the business.”

There is quite a bit of activity around Mars. The National Space Administration of China (CNSA) is collecting data from its very first rover, Zhurong, which has been on the surface of Mars since May 14. The rover explores the area around its landing site at Utopia Planitia and gathers important information. on the surface and inside the red planet.
However, he cannot bring this data back to Earth on his own. Instead, it requires the help of orbiters such as the European Space Agency’s (ESA) Mars Express. Why?
Rovers like the Zhurong don’t carry the equipment they would need to transmit data directly to Earth, as it would take up too much space for space experiments. They are instead equipped with small, short-range radios similar to those possessed by the spacecraft orbiting Mars, such as ESA’s Mars Express.
Rovers use these radios to send their data to roving orbiters on Mars, which then send it back to Earth where scientists anxiously await to receive and analyze it. And it is (relatively) common to share orbiters for information relay purposes when the rover’s preferred orbiter is not there.
So far, Zhurong has used the Chinese Tianwen-1 orbiter he arrived with to send information to Earth. But starting in November, ESA’s Mars Express will undertake five tests in which it will attempt to listen to Zhurong and send back the information it captures to ESA’s ESOC operations center in Darmstadt, according to a blog by ESA.
There is however a catch: due to an incompatibility between the two radio systems, the Zhurong rover cannot receive the frequencies used by Mars Express. Fortunately however, he is capable of transmitting a frequency compatible with Mars Express.
How will it work?
When Mars Express reaches the space above the Zhurong landing site at Utopia Planitia, it will turn on its radio and simply listen and record all incoming data. Once it has accumulated all the information it can collect, the spacecraft will turn to Earth and transmit the data through space to ESOC. ESOC will then share the data it receives with the Zhurong team for processing and analysis.

These features are outlined below. Peripheral vs. central processing unit Experience with an earlier prototype [BBB94] indicated that the microprocessor subsystem, which was responsible for managing data transfers between the wireless modem and the I/O-processing chipset, consumed a significant fraction of the overall power budget and was also a primary performance bottleneck. The most delay-sensitive activities, such as moving the pen and expecting the cursor to track location in real-time, typically generate a large number of very small data transfers, so that the microprocessor spends the majority of its cycles entering and exiting interrupt service routines and setting up data transfers.
Before proceeding, it is beneficial to take a brief look at the history of protocol design, protocol specification, and the various technical tools that have been used to verify correctness and estimate performance. 3 Abstract Services and the OSI Protoc o l “Stack” Because it is the most common decomposition of protocol services, a good starting point for discussing communication protocols is the Open Systems Interconnection (OSI) “protocol stack” [DZ83]. In the OSI model, protocols are conceptually 10 organized as a series of layers, each one built upon its predecessor.
4 An approach to integrating protocol design disciplines This above example attests to the need to tailor protocols to the environment they operate in, and is the strongest argument for a design methodology that integrates performance metrics with functional correctness. Separating the design of the protocol from the context in which it exists leads to performance penalties that are unacceptable for wireless, portable applications. The remainder of this dissertation explores the relationships between specification, verification, performance estimation, and implementation.


Denna har analoga ingångar + ett superfint riaa-steg inbyggt. No:5802 har fler digitala ingångar, men dock inga analoga.
Analog Input Stage
The foundation of the Nº5805 is its proprietary PureDirect™ signal path-a fully discrete, direct-coupled, dual-monaural line-level preamp circuit, for which the Shelton design team has two patents pending. A unique single gain stage mated to a digitally controlled resistor network for volume adjustment maintains maximum signal integrity and widest possible bandwidth. Each of its three stereo line level inputs—one balanced XLR and two single-ended, using custom Mark Levinson RCA connectors—has its own individual high-reliability signal switching relays.
A newly designed Phono stage features a hybrid gain topology, mating key discrete components from the acclaimed Nº 500 series Pure Phono stage with low-noise integrated circuits for high performance at lower cost. Also like the Nº 500 series, a hybrid active/passive RIAA equalizer employs precision resistors and polypropylene capacitors for exceptional accuracy and sonic clarity. The user can select MM/MC gain and infrasonic filter from the setup menu, while capacitive and resistive loading settings are easily accessed from the rear panel.
The fully discrete, direct-coupled, class AB amplifier channels get their power from an oversized (500+ VA) toroidal transformer with individual secondary windings for the left and right channels. The voltage gain stage employs a topology directly descended from the acclaimed Nº 534 amplifier, which is mated to an output stage comprising two high-speed driver transistors operating in class A and six 260V, 15A output transistors. Two Thermal-Trak devices in a unique configuration guarantee stable output bias regardless of load or temperature. Four 10,000-microfarad capacitors per channel, located directly on the output stage circuit board, easily provide enough current for a conservative 125W/channel at 8 ohms, nearly 250W/channel at 4 ohms, and stable operation down to 2 ohms. Variable line-level RCA outputs allow system expansion and flexibility.
Building upon the superb analog platform, the Nº 5805 adds equally outstanding digital audio capability with the Mark Levinson PrecisionLink II™ DAC. The latest generation ESS Sabre 32-bit D/A converter with jitter elimination circuitry and a fully balanced, discrete current-to-voltage converter form the heart of the digital audio processing stage. Four digital audio inputs are provided: one coaxial and two optical S/PDIF, and one asynchronous USB for playback of high resolution PCM (up to 192kHz/32 bits) and DSD (up to DSD 5.6) files. The No 5805 includes MQA (Master Quality Authenticated) technology, which enables playback of MQA audio files and streams. A Bluetooth receiver equipped with AptX-HD enables the highest quality Bluetooth playback available.

DAB Receiver Market: Introduction
- DAB, or digital audio broadcasting, is a form of radio that relies on digitally transmitted data, made of ones and zeros. The transmitter encodes binary data and transmits it from a station, which gets picked up by a receiver that decodes the data and processes it into music that gets played through the speakers.
- In digital radio, fragments can be sent over numerous times in order to improve the chances of them being picked up by a digital receiver. The computer chip in the digital receiver is able to process the arriving fragments into sound, even if they were received in different instances and from different sources. Numerous different digital radio stations exist within a specific area, and do not interfere with each other, providing variety of choice to users.
- DAB is more robust as it possesses the capability to travel over a larger area as compared to analog signals, reference to noise and multipath fading for mobile listening. DAB guarantees a clean, continuous stream of audio, as long as it can stay within reception of a digital radio signal.

A virtual private network VPN is a service that allows a user to establish a secure, encrypted connection between the public internet and a corporate or institutional network. A secure sockets layer VPN SSL VPN enables individual users to access an organization's network, client-server applications, and internal network utilities and directories without the need for specialized software.
SSL VPNs provide safe, secure communication via an encrypted connection for all types of devices, regardless of whether access to the network is via the public internet or another secure network. Instead, the SSL VPN automatically uses the newest, most updated cryptographic protocol that has been installed on the user's browser.
Users do not need to worry about updating the protocol on their browser either. Whenever a browser or an operating system OS is updated, the newest version of the protocol is updated along with it. Additionally, the user can access a variety of specific applications or private network services as defined by the organization. Users can typically enter the gateway, or the hardware on a network that allows data to flow from one network to another, using any modern web browser, by entering the username and password provided by the VPN gateway service.
A heavyweight technology, IPsec uses a combination of both hardware and software to mimic the qualities of a computer terminal connected to an organization's local-area network LAN , allowing access to anything that an internal computer could. This is because IPsec works on the network layer of the Open Systems Interconnection OSI model and must be managed physically by network engineers rather than via software.
Most IPsec VPN solutions require the installation of both special hardware and software for a user to gain access to the network. The main benefit of this setup is the extra layers of security. When the network is protected not only by software but also by hardware, it is more difficult for cyber criminals to infiltrate the network and steal critical data. Conversely, the downside of IPsec VPNs is that they can be expensive and cumbersome to buy, install, and maintain the licenses for both the hardware and software systems needed.
In today's work-from-home environments, this type of setup would require the shipping of IPsec VPN hardware to each employee, instructing each on how to download the software and manage the usage, maintenance, and updating moving forward—a high level of responsibility and stress on the organization. Instead, SSL is supported by most modern web browsers and does not require any additional installations. This can be helpful when networkwide access is unnecessary.
For example, certain employees or contractors might not need access to certain applications that others do. SSL VPN technology can ensure that those individuals receive different administrative access rights depending on their positions.
However, to restrict certain employees from accessing specific applications, the involvement of IT staff is needed to authorize access. This could require additional cost.

The candidate should be able to configure a network device to implement various network authentication schemes. This objective includes configuring a multi-homed network device, configuring a virtual private network and resolving networking and communication problems.
This objective has a weight of 4 points
Key Knowledge Areas:
The following is a partial list of used files, terms, and utilities:
VPN stands for Virtual Private Network. A VPN uses the Internet as its transport mechanism, while maintaining the security of the data on the VPN. What does a VPN do? It allows you to connect two or more remote networks securely over an insecure connection. The reason it is called virtual is that there is no physical connection between the two networks. Instead a non-dedicated secure tunnel is created through an insecure connection (like the Internet). This tunnel is generally encrypted and is only decrypted when it arrives at the destination host.
Why would you need such a network? In today's connected world, employees always need access to the data on the corporate network. Until recently this was done by dialing directly into the servers. The issue with this is that long-distance bills can be expensive as well as the cost of equipment and extra phone lines. By letting the employee connect via local internet access wherever he is, the costs are dramatically reduced.
Another reason for implementing a VPN is to integrate the LANs in several office or branches. By connecting the two networks, a user in Los Angeles can access network services in New York while still using their regular Internet connection.
There are many ways to implement a VPN. Many companies use proprietary software implementations while others use their routers because many routers have VPN support built in. These VPNs can be as simple as an SSH tunnel or very complicated. But all implementations create a virtual tunnel through an insecure network. Some VPN implementations include:
OpenVPN is a free and open source software application that implements virtual private network (VPN) techniques for creating secure point-to-point or site-to-site connections in routed or bridged configurations and remote access facilities. It uses SSL/TLS security for encryption and is capable of traversing network address translators (NATs) and firewalls.
OpenVPN allows peers to authenticate each other using a pre-shared secret key, certificates, or username/password. When used in a multiclient-server configuration, it allows the server to release an authentication certificate for every client, using signature and Certificate authority. It uses the OpenSSL encryption library extensively, as well as the SSLv3/TLSv1 protocol, and contains many security and control features.
OpenVPN is available on almost any modern operating system and can be built from source or installed as a pre-built package.
OpenVPN is not compatible with IPsec or any other VPN package. The entire package consists of one binary for both client and server connections, an optional configuration file, and one or more key files depending on the authentication method used.
This example uses static keys for authentication. This is a very simple setup, ideal for point-to-point networking.
A VPN tunnel will be created with a server endpoint of 10.10.10.10 and a client endpoint of 10.10.10.11. The public ipaddress of the server is referenced by vpnserver.example.com The communication between these endpoints will be encrypted and occur over the default OpenVPN port 1194.
To setup this example a key has to be created: openvpn --genkey --secret static.key.
Copy this key (
static.key) to both client and server.
Server configuration file (server.conf):
dev tun ifconfig 10.10.10.10 10.10.10.11 keepalive 10 60 ping-timer-rem persist-tun persist-key secret static.key
Client configuration file (client.conf):
remote vpnserver.example.com dev tun ifconfig 10.10.10.11 10.10.10.10 keepalive 10 60 ping-timer-rem persist-tun persist-key secret static.key
Start the vpn on the server by running openvpn server.conf and running openvpn client.conf on the client.
A more full-blown approach to VPN tunnels is the IPSEC protocol. IPSEC provides encryption and authentication services at the IP (Internet Protocol) level of the network protocol stack. IPSEC can be used on any machine which does IP networking. Dedicated IPSEC gateway machines can be installed wherever required to protect traffic. IPSEC can also run on routers, on firewall machines, on various application servers and on end-user desktop or laptop machines.
The basic idea of IPSEC is to provide security functions, authentication and encryption at the IP-level. This requires a higher-level protocol (IKE) to set things up for the IP-level services (ESP and AH).
Three protocols are used in an IPSEC implementation:
Encrypts and/or authenticates data;
Provides a packet authentication service;
Negotiates connection parameters, including keys, for the other two.
The term IPSEC is slightly ambiguous. In some contexts, it includes all three of the above, but, in other contexts, it refers only to AH and ESP.
KLIPS (kernel IPSEC) implements AH, ESP and packet handling within the kernel (2.4).
NETKEY is the Kernel IPSec implementation included with the 2.6 kernel.
Pluto (an IKE daemon) implements IKE, negotiating connections with other systems.
various scripts provide an administrator interface to the machinery.
The config file contain three parts:
Each connection section starts with
ident is an arbitrary name
which is used to identify the connection.
This section starts with
conn %default. For each parameter in it,
any section which does not have a parameter of the
same name gets a copy of the one from the
%default section. There may
be multiple %default sections, but only one
default may be supplied for any specific parameter
name and all
sections must precede all
%default sections of
A sample configuration file is shown below:
# basic configuration config setup interfaces="ipsec0=eth0" klipsdebug=none plutodebug=none plutoload=%search plutostart=%search # Close down old connection when new one using same ID shows up. uniqueids=yes # defaults that apply to all connection descriptions conn %default # How persistent to be in (re)keying negotiations (0 means very). keyingtries=0 # How to authenticate gateways authby=rsasig # VPN connection for head office and branch office conn head-branch # identity we use in authentication exchanges firstname.lastname@example.org leftrsasigkey=0x175cffc641f... left=184.108.40.206 leftnexthop=220.127.116.11 leftsubnet=192.168.11.0/24 # right s.g., subnet behind it, and next hop to reach left email@example.com rightrsasigkey=0xfc641fd6d9a24... right=18.104.22.168 rightnexthop=22.214.171.124 rightsubnet=192.168.0.0/24 # start automatically when ipsec is loaded auto=start
To avoid trivial editing of the configuration file for
each system involved in a connection,
specifications are written in terms of
right participants, rather than in
terms of local and remote. Which participant is considered
right is arbitrary; IPSEC figures
out on which it is running on based on internal
information. This permits identical connection
specifications to be used on both ends.
leftnexthop (and the
right... counterparts) determine
the layout of the connection:
leftrsasigkey are used in
authenticating the left participant. The
leftrsasigkey is the public key of
the left participant (in the example above the RSA keys
are shortened for easy display). The private key is stored
/etc/ipsec.secrets file and
should be kept secure.
The keys can be generated on both client and server with the command:
# ipsec rsasigkey --verbose 2048 > rsa.key
The IKE-daemon of IPSEC is called pluto. It will authenticate and negotiate the secure tunnels. Once the connections is set up, the kernel implementation of IPSEC can route traffic through the tunnel.
the pluto daemon to search the
configuration file for
statements. All connections with
auto=add will be loaded in the
pluto database. Connections with
auto=start will also be started.
Network troubleshooting is a very broad subject with thousands of tools available. There are some very good books available on this topic, so we will limit our discussion to an overview of some of the tools which can be used to solve or detect network problems.
ifconfig checks the network interface configuration. Use this command to verify the user's configuration if the user's system has been recently configured or if the user's system cannot reach the remote host while other systems on the same network can.
When ifconfig is entered with an interface name and
no other arguments, it displays the current values assigned
to that interface. For example, checking interface
eth0 system gives this report:
$ ifconfig eth0 eth0 Link encap:Ethernet HWaddr 00:10:60:58:05:36 inet addr:192.168.2.3 Bcast:192.168.2.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1398185 errors:0 dropped:0 overruns:0 frame:0 TX packets:1411351 errors:0 dropped:0 overruns:0 carrier:0 collisions:829 txqueuelen:100 RX bytes:903174205 (861.3 Mb) TX bytes:201042106 (191.7 Mb) Interrupt:11 Base address:0xa000
The ifconfig command displays a few lines of output. The third line of the display shows the characteristics of the interface. Check for these characteristics:
The interface is enabled for use. If the interface is “down”, bring the interface “up” with the ifconfig command (e.g. ifconfig eth0 up).
This interface is operational. If the interface is not “running”, the driver for this interface may not be properly installed.
The second line of ifconfig output shows the IP address, the subnet mask and the broadcast address. Check these three fields to make sure the network interface is properly configured.
Two common interface configuration problems are misconfigured subnet masks and incorrect IP addresses. A bad subnet mask is indicated when the host can reach other hosts on its local subnet and remote hosts on distant network, but cannot reach hosts on other local subnets. ifconfig quickly reveals if a bad subnet mask is set.
An incorrectly set IP address can be a subtle problem. If the network part of the address is incorrect, every ping will fail with the “no answer” error. In this case, using ifconfig will reveal the incorrect address. However, if the host part of the address is wrong, the problem can be more difficult to detect. A small system, such as a PC that only connects out to other systems and never accepts incoming connections, can run for a long time with the wrong address without its user noticing the problem. Additionally, the system that suffers the ill effects may not be the one that is misconfigured. It is possible for someone to accidentally use your IP address on his own system and for his mistake to cause your system intermittent communications problems. This type of configuration error cannot be discovered by ifconfig, because the error is on a remote host. The arp command is used for this type of problem.
The ifconfig command can be used to set up multihomed network device. There are two ways a host can be multihomed.
Two Or More Interfaces To The Same Network: Devices such as servers or high-powered workstations may be equipped with two physical interfaces to the same network for performance and/or reliability reasons. They will have two IP addresses on the same network with the same network ID.
Interfaces To Two Or More Different Networks: Devices may have multiple interfaces to different networks. The IP addresses will typically have different network IDs in them.
The basic format of the ping command on a Linux system is:
$ ping [-c
The hostname or IP address of the remote host being tested.
The number of packets to be sent in the test. Use the count field and set the value low. Otherwise, the ping command will continue to send test packets until you interrupt it, usually by pressing CTRL-C (^C).
$ ping -c 4 www.snow.nl PING home.NL.net (126.96.36.199): 56 data bytes 64 bytes from 188.8.131.52: icmp_seq=0 ttl=245 time=32.1 ms 64 bytes from 184.108.40.206: icmp_seq=1 ttl=245 time=32.1 ms 64 bytes from 220.127.116.11: icmp_seq=2 ttl=245 time=37.6 ms 64 bytes from 18.104.22.168: icmp_seq=3 ttl=245 time=34.1 ms --- home.NL.net ping statistics --- 4 packets transmitted, 4 packets received, 0% packet loss round-trip min/avg/max = 32.1/33.9/37.6 ms
This test shows a good wide-area network link to
with no packet loss and fast response. A small
packet loss, and a round-trip time an order of magnitude
higher, would not be abnormal for a connection made across a
wide-area network. The statistics displayed by the ping
command can indicate a low-level network problem. The key
How long it takes a packet to make the round trip, displayed in milliseconds after the string time=;
The percentage of packets lost, displayed in a summary line at the end of the ping output.
If the packet loss is high, the response time is very high or packets are arriving out of order, there could be a network hardware problem. If you see these conditions when communicating over great distances on a wide area network, there is nothing to worry about. TCP/IP was designed to deal with unreliable networks, and some wide-area networks suffer from a high level of packet loss. But if these problems are seen on a local-area network, they indicate trouble.
On a local-network cable segment, the round-trip time should be near 0, there should be little or no packet loss and the packets should arrive in order. If these things are not true, there is a problem with the network hardware. On an Ethernet, the problem could be improper cable termination, a bad cable segment or a bad piece of “active” hardware, such as a hub, switch or transceiver.
The results of a simple ping test, even if the ping is successful, can help direct you to further testing toward the most likely causes of the problem. But other diagnostic tools are needed to examine the problem more closely and find the underlying cause.
$ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.11.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 22.214.171.124 0.0.0.0 255.255.252.0 U 0 0 0 eth1 0.0.0.0 126.96.36.199 0.0.0.0 UG 0 0 0 eth1
This host has two interfaces, one on subnet 192.168.11.0/24
the other on subnet 188.8.131.52/22. There is also a default
route out on
eth1 to 184.108.40.206
(denoted by the
G under “Flags” and a
“Destination” and “Genmask” of 0.0.0.0).
To be able to troubleshoot this information you need to know what the routing should be, perhaps by saving the routing information when the system is known to work.
The two most common mistakes are:
No network entry for an interface. When a network interface is configured a routing entry should be added that informs the kernel about the network that can be reached through the interface.
No default route (or two default routes). There should be exactly one default route. Note that two default gateways can go undetected for a long time because the routing could “accidentally” use the proper gateway.
In general, if there is a routing problem, it is better to first locate the part of the network where the problem originates, e.g. with ping or traceroute and then use route as part of the diagnostics.
traceroute is a tool used to discover the links along a path. Path discovery is an essential step in diagnosing routing problems.
The traceroute is based on a clever use of the Time-To-Live (TTL) field in the IP packet's header. The TTL field is used to limit the life of a packet. When a router fails or is misconfigured, a routing loop or circular path may result. The TTL field prevents packets from remaining on a network indefinitely should such a routing loop occur. A packet's TTL field is decremented each time the packet crosses a router on its way through a network. When its value reaches 0, the packet is discarded rather than forwarded. When discarded, an ICMP TIME_EXCEEDED message is sent back to the packet's source to inform the source that the packet was discarded. By manipulating the TTL field of the original packet, the program traceroute uses information from these ICMP messages to discover paths through a network.
traceroute sends a series of UDP packets with the destination address of the device you want a path to. By default, traceroute sends sets of three packets to discover each hop. traceroute sets the TTL field in the first three packets to a value of 1 so that they are discarded by the first router on the path. When the ICMP TIME_EXCEEDED messages are returned by that router, traceroute records the source IP address of these ICMP messages. This is the IP address of the first hop on the route to the destination.
Next, three packets are sent with their TTL field set to 2. These will be discarded by the second router on the path. The ICMP messages returned by this router reveal the IP address of the second router on the path. The program proceeds in this manner until a set of packets finally has a TTL value large enough so that the packets reach their destination. Most implementations of traceroute default to trying only 30 hops before halting.
An example traceroute on linux looks like this:
$ traceroute vhost2.cistron.net traceroute to vhost2.cistron.net (220.127.116.11), 30 hops max, 38 byte packets 1 gateway.kabel.netvisit.nl (18.104.22.168) 56.013 ms 19.120 ms 12.642 ms 2 22.214.171.124 (126.96.36.199) 138.138 ms 28.482 ms 28.788 ms 3 asd-dc2-ias-ar10.nl.kpn.net (188.8.131.52) 102.338 ms 240.596 ms 253.462 ms 4 asd-dc2-ipc-dr03.nl.kpn.net (184.108.40.206) 95.325 ms 76.738 ms 97.651 ms 5 asd-dc2-ipc-cr01.nl.kpn.net (220.127.116.11) 61.378 ms 60.673 ms 75.867 ms 6 asd-sara-ipc-dr01.nl.kpn.net (18.104.22.168) 111.493 ms 96.631 ms 77.398 ms 7 asd-sara-ias-pr10.nl.kpn.net (22.214.171.124) 78.721 ms 95.029 ms 82.613 ms 8 ams-icr-02.carrier1.net (126.96.36.199) 90.179 ms 80.634 ms 112.130 ms 9 188.8.131.52 (184.108.40.206) 49.521 ms 80.354 ms 63.503 ms 10 220.127.116.11 (18.104.22.168) 94.528 ms 60.698 ms 103.550 ms 11 vhost2.cistron.net (22.214.171.124) 102.057 ms 62.515 ms 66.637 ms
Again, knowing what the route through your network should be, helps to localize the problem. Note that not all network problems can be detected with a traceroute, because of some complicating factors. First, the router at some hop may not return ICMP TIME_EXCEEDED messages. Second, some older routers may incorrectly forward packets even though the TTL is 0. A third possibility is that ICMP messages may be given low priority and may not be returned in a timely manner. Finally, beyond some point of the path, ICMP packets may be blocked.
The results of a traceroute is a great tool to narrow down the possible causes of a network problem.
arp is used to manipulate the kernel's ARP cache. The primary options are clearing an address mapping entry and manually setting one up. For debugging purposes, the arp program also allows a complete dump of the ARP cache.
If you know what the ARP address of a specific host should be, the dump may be used to determine a duplicate IP-address, but running arpwatch on a central system might prove more effective.
arpwatch keeps track of ethernet/IP address pairings. Changes are reported via syslog and e-mail.
arpwatch will report a “changed ethernet address” when a known IP address shows up with a new ethernet address. When the old ethernet address suddenly shows up again, a “flip flop” is reported.
Detection of duplicate IP addresses is very hard even with arpwatch. if, for example, a rogue host uses the IP address of the host running the arpwatch program or never communicates with it, a duplicate IP address will go unnoticed. Still, arpwatch is a very useful tool in detecting networking problems.
tcpdump is a program that enables network administrators to inspect in real-time every packet going through the network to which his or her computer is attached. This tool is typically used to monitor active connections or troubleshoot occasional network connectivity problems.
tcpdump can generate a lot of output, so
it may be useful to limit the reported packets by specifying
a port (e.g.
tcpdump port 80). There are lots of other ways to
specify which packets and what information we are interested
in - see the manpage of tcpdump for more
nmap is a versatile tool for network exploration and security auditing. It's main use is as a portscanner, which also can identify running services, versions of the running services and OS types.
An example of this command and output is:
# nmap -O -v localhost Starting Nmap 5.50 ( http://nmap.org ) at 2011-05-16 11:15 CEST Initiating SYN Stealth Scan at 11:15 Scanning localhost (127.0.0.1) [1000 ports] Discovered open port 22/tcp on 127.0.0.1 Discovered open port 25/tcp on 127.0.0.1 Discovered open port 111/tcp on 127.0.0.1 Discovered open port 631/tcp on 127.0.0.1 Completed SYN Stealth Scan at 11:15, 0.03s elapsed (1000 total ports) Initiating OS detection (try #1) against localhost (127.0.0.1) Nmap scan report for localhost (127.0.0.1) Host is up (0.00011s latency).

wireshark (known as Ethereal until a trademark dispute in the summer of 2006) is an open source network protocol analyzer. It allows you to examine data from a live network or from a capture file on disk. You can interactively browse the capture data, delving down into just that level of packet detail you need.
Wireshark has several powerful features, including a rich display filter language and the ability to view the reconstructed stream of a TCP session. It also supports hundreds of protocols and media types. A tcpdump-like console version named tethereal is included. One word of caution is that Ethereal has suffered from dozens of remotely exploitable security holes, so stay up-to-date and be wary of running it on untrusted or hostile networks (such as security conferences).
The lsof command lists all open files on a system. Since Linux treats everything as a file, it also shows open network sockets. It can be used to find open ports on a system as well as determining the origin of a network connection.
Options of the lsof used for network troubleshooting.
List IP sockets. The -i option also takes arguments to restrict the sockets listed, like -i tcp or -i 192.168.1.2.
Do not resolve hostnames; can make lsof run faster.
Do not resolve port names; can make lsof run faster.
Resolve port name to protocol; default behaviour.
Like lsof,netstat is a program to list open ports on a system. It looks for the standard ports, but it also finds custom ports opened by applications, for instance netcat.
Frequently used options are:
List all sockets.
List only IP connections
Only show listening sockets
Show IP numbers instead of resolving them to hostnames.
Show the PID number and name of the process that is holding the socket.
Show the kernel routing table. Is the same as the route command.
nc Is used for arbitrary TCP and UDP connections and listens. The command allows the user to set up, analyze and read connections between systems. It is a very useful tool in the troubleshooting toolbox. nc Can be used to open up any port the user wants to be opened.
Because nc is capable of connecting and listening to any port it can be used to transfer files between systems that lack Samba, FTP or SSH etc.
if nmap is not available the nc command can be used to check for open ports: Run nc command with -z flag. You need to specify host name / ip along with the port range to limit and speedup operation. eg.
# nc -z localhost 1-1023

Critical Reasons for Using Custom Resistors
Custom resistors often are integral to the manufacture of custom electronic equipment. Today, the widespread application of electronic gadgets meant to make life better for humans have made it important for designers to incorporate custom resistive technology in their designs. Over a couple of decades, technology has upgraded to the point of creating better-quality electronic gadgets with components boasting high reliability and performance. It is the technological progress that has led to the development of precision resistors, facilitating models with significantly tiny parts.
Some applications of high precision resistors include the design of electronic gadgets deployed in life-saving situations. For instance, the technology is important in the making of healthcare equipment like tiny insulin-pumping devices. The tech is also useful in life-saving situations like defibrillation machines or helping an individual to breath.
In plane-making, high-precision resistive technology is involved in the creation of instruments that enhance the safety of flight. The technology has widespread application in the commercial airline industry. The number of technological applications that rely on the cutting-edge resistive tech is almost infinite.
For sure, you’ll find the best precision resistor makers useful if you need to make cutting-edge electronic devices. Such experts come up with the highest-quality designs and components for a wide spectrum of applications. The end product is resistors you can trust to perform consistently well throughout.
It is imperative for high-precision resistors to avoid any slight or big weakness in their inherent design. That’s the only way the custom resistive technology can guarantee the delivery of strong and reliable electronic devices, no matter your industry. Such elements remain steady now and over the long run, always responding well to frequency.
High-precision resistors with superior performance are extremely useful where the electronic needs call for capacity to survive any predicted temperature changes. Nonetheless, the objective does not mean the structural integrity of the resistor has to be affected. In addition, engineers take into account the different types of stressors that the resistive component may be exposed to. In a nutshell, the best precision resistor supplier should embrace anticipatory planning. What follows is the incorporation of the right solutions to produce state-of-the-art electronic components.
The good thing about ordering custom resistors is that you can first ask questions about the manufacturing process and how testing for the best quality and performance is done. Still, the manufacturer takes into account your custom parameters in the design and development of technology that satisfies your particular needs.
Be sure to pick a custom resistor maker with the expertise and experience to create the right type of component for your application. Whether you’re looking for wirewound or thick/thin film resistive technology for your specialized device, choose a manufacturer who boasts in-depth awareness of your particular application.
News For This Month: Services


In recent years, having reliable, quality, and secure Internet access has become a necessity. We have gone from having an access point (the classic desktop PC that the whole family shared) to multiple devices that simultaneously connect to the network and exchange a large amount of information between them. In this guide, we review some useful tips to improve the quality of your connection at home.
Choose well where you place the router
Although manufacturers have been improving over the years, most routers are so ugly that we don’t like to have them in plain sight. It is not a good idea; the device’s position can affect the quality of the wireless connection, and, also, they are usually very sensitive to temperature.
Use quality cabling
Not all cables are the same, and the differences go far beyond color. Although in terms of distance, they should all work well below 100 meters, not all manufacturers put the same care in details such as construction quality, shielding against electromagnetic interference, or shielding the braiding of the copper wires.
Obviously, it does not make sense to spend a lot of money on the meter, and a half cable that connects the router to your console (in fact, the one that the manufacturer includes is more than enough), but things change when it comes to setting up a local network. It is important to note that the Ethernet cables will share space with those of the electrical network. Choosing some Cat6 will not cost you too much and is a guarantee for the future.
Optimize your WiFi connectivity
As most of our readers will already know, the WiFi communication standard has improved exponentially over the years. Thus, each generation is a really important leap in terms of performance and coverage.
It is important to bear in mind that having an 802.11 ac WiFi router is useless if our devices are not able to take advantage of it. Therefore, and although the transactions are always complicated, always invest a little in a quality router since it is the most important device in our network. So we renew smartphones, tablets, computers, and other devices, we can take advantage of the new standard. Otherwise, we would have a significant limitation on the quality of our connection.


- A high-quality mesh Wi-Fi system should be easy to install, capable of providing high-speed Internet to every corner of your home, and supported by a useful app with plenty of features.
- I like the TP-Link Deco M4 Whole Home Mesh Wi-Fi System because it covers homes of up to 5,500 square feet, provides connectivity for 100 devices, and has effective parental controls.
- The Deco M4 is reasonably affordable at $168 on Amazon and comes with a two-year warranty and feature-packed app.
About a year ago, my family moved to Michigan after we got a good deal on a giant historic home. But with the nice price came an endless stream of headaches.
In addition to having to put tens of thousands of dollars into repairing the place, it was hard to find a good router capable of providing Wi-Fi to every room. This is a must since both my wife and I work from home.
So far, we've found that mesh Wi-Fi systems are the only things that can reach every nook and cranny of our lair. These are multi-device systems consisting of a main router and one or more satellites, or extenders. Of the half dozen or so mesh systems I've tested, the TP-Link Deco M4 Mesh Wi-Fi System is the most affordable and has the best parental controls.
Read more: The best mesh Wi-Fi systems you can buy
At $168, the Deco M4 is reasonably priced and comes with three routers; set up took around 30 minutes
The Deco M4 comes with three identical routers, all cylindrical and white so they'll blend into any home. One serves as the main router and connects directly to your modem. The other two are satellites designed to extend the reach of your Wi-Fi coverage.
Here are the specs of the system:
- Dual-Band (5 GHz and 2.4 GHz)
- Each unit has two ethernet ports
- Covers 5,500 square feet as a system
- Provides connectivity for up to 100 devices
- 2-year warranty
- 24/7 technical support
- Controllable with Alexa
- WPA/WPA2 wireless encryption
- Wireless type: 802.11a/b/g/n/ac
For more specs, check out the Deco M4's product page.
Setup was seamless, and I didn't experience any hiccups along the way.
It only took about half an hour from opening the box until I was able to stream a video on my computer. This was relatively fast since I was essentially installing three routers instead of one.
The app provided step-by-step directions that were easy to follow too in case you don't know how to. As I installed each router, it gave me helpful tips on where to position them in my house. Once everything was in place, I updated the firmware and was ready to go.
Speeds didn't slow down even when I used more than eight devices at once
Though the speeds aren't amazing, the Deco M4 provides good enough Internet to every corner of my 4,000-square-foot home and beyond. Right next to the modem, the Wi-Fi speeds were 185.2 Mbps download and 222.1 Mbps upload in my tests.
In my office, next to one of the satellites, the Wi-Fi speeds were 17.8 Mbps download and 17.3 upload. With a wired connection to the satellite, there was a slight bump in speeds — 20.6 Mbps download and 38.3 Mbps upload.
In the far corner of my unfinished basement, which is a floor below and 50 feet away from the main router, I still had 17.9 Mbps downloads and 14.4 Mbps uploads. And in front of my neighbor's house, about 100 feet from the modem, the speeds were 7.2 Mbps download and 4.9 Mbps upload.
Best of all, when we run several devices at once including three computers, three phones, a tablet, an Xbox, and countless smart home units, we don't notice any degradation of streaming quality or any slow page-load speeds.
The parent controls work as advertised too. With so many router brands moving toward paid parental control subscriptions, it's refreshing to find a system supported by free and effective parental controls.
There are several ways to control your children's access. With the app, you can block specific sites, which can help with productivity. You can also block content based on what is age-appropriate, and set usage time limits or specify what times you want the Internet to be turned off on certain devices. In my tests, all of these services worked well.
Your Internet speed will be limited by the router's max speed of 867 Mbps
Depending on how fast your Internet service is supposed to be and whether you gave a wired or Wi-Fi connection, you might feel slowed down by the router.
The Deco M4 is a dual-band AC1200 router, so it can reach speeds up to 1200 Mbps total between its two bands — 5 GHz and 2.4 GHz. This works out to an 867 maximum on the 5 GHz band and 300 on the 2.4 GHz. I have fiber optic Internet that's supposed to be able to reach 1 Gbps speeds. With this router's max of 867 Mbps on a single band, I can't experience the most out of my Internet.
However, this should be taken with a giant grain of salt. The 1 Gbps speed for my Internet is based on a wired connection, not Wi-Fi. The fastest Wi-Fi speed I've achieved using any router is 400 Mbps, well below the Deco M4's limit. So unless you're moving around massive files, you won't notice a difference between 867 Mbps and 1 Gbps speeds.
I wish there were more ethernet ports on the routers. I have several devices that require a wired connection, and even one or two more ports would have been helpful. Fortunately, for less than $20, you can get a switch that will add four more ports.
I'd recommend the Deco M4 system for anyone who wants consistent Wi-Fi around their home for less than $200
Though the speeds didn't break any records, I was impressed with how well the Deco M4 performed despite its sub-$200 price tag.
Should you buy it?
If your house is between 3,000 and 5,500 square feet, the TP-Link Deco M4 Whole Home Mesh Wi-Fi System is one of the most cost-effective mesh systems that'll reach every corner of your home and then some.
It'll serve the needs of homeowners, but if you're hoping to play graphics-intensive computer games on a Wi-Fi network in the basement or far corner where noise doesn't travel, you may have trouble getting the speeds you want. If this happens, I'd recommend connecting to the main router via a long ethernet cord or spending extra on one of the alternatives below.
What are your alternatives?
Below are three mesh systems that I've personally tested that cost significantly more than the Deco M4 but provide faster speeds throughout my 4,000-square-foot home:
- Gryphon Smart Mesh Wi-Fi System ($399) — At this price, you get two units, which was what I used in my home. It's the best mesh system I've tested and it provided fast speeds to more than a dozen devices throughout my home. The biggest negative was the parental controls. There are several ways to control content, but they didn't always work as they were supposed to. Read my full review here.
- Netgear Orbi Voice Whole Home Mesh Wi-Fi System ($370.68) — This two-unit system is unique because the satellite doubles as a high-quality speaker that's compatible with Alexa. The Orbi Voice offered excellent speeds throughout my house even when several devices were in use. The parental controls were a negative with this as well. For full functionality, you have to buy a subscription to the Circle app. Read my full review here.
- TP-Link Deco M9 Smart Hub & Whole Home Wi-Fi Mesh System ($227.28) — Another TP-Link router, the two-unit Deco M9 system had impressive coverage. I placed one unit by the modem and the other on the third floor, and received seamless Wi-Fi everywhere. It may be worth spending $60 extra (compared to the M4) for the bump in Wi-Fi speeds. Read my full review here.
Overall, I'm a fan of the TP-Link Deco M4. I strongly recommend picking it up if you're looking for a device that can reach every corner of a home of up to 5,500 square feet, especially if you want to control your children's internet usage.
Pros: Covers 5,500 square feet, can be used with up to 100 devices at once, excellent parent controls, intuitive app, affordable given comparable alternatives
Cons: Network speeds have a low upper limit (AC1200), only two ethernet ports on each unit
