Top Ten Basic Networking Commands Inwards Linux/Unix
Networking is an essential business office Unix in addition to it offering lots of tools in addition to ascendency to diagnose whatever networking problem. When I was working on FIX Protocol nosotros larn a lot of back upwards queries to come across whether FIX Sessions are connected or not. Since FIX Protocol uses sockets you lot tin exercise the netstat , telnet in addition to other networking commands available inward Linux for finding a work in addition to solve that.In this article, I volition present you lot basic networking commands inward Unix in addition to for what role they are used. alongside the combination of grep and find ascendency on them, you lot tin troubleshoot around of the networking problem.
These are around useful commands inward my listing acre working on Linux server , this enables you lot to chop-chop troubleshoot connexion issues e.g. whether simply about other arrangement is connected or non , whether simply about other host is responding or non in addition to acre working for FIX connectivity for advanced trading arrangement this tools saves quite a lot of fourth dimension .
This article is inward continuation of my article How to operate fast inward Unix in addition to Unix Command tutorials in addition to Examples for beginners.
• finding host/domain lift in addition to IP address - hostname
• examination network connexion – ping
• getting network configuration – ifconfig
• Network connections, routing tables, interface statistics – netstat
• enquiry DNS lookup lift – nslookup
• communicate alongside simply about other hostname – telnet
• outing steps that packets stimulate got to larn to network host – traceroute
• sentiment user information – finger
• checking condition of goal host - telnet
For a consummate listing of UNIX commands, you come across The Linux Command Line: Influenza A virus subtype H5N1 Complete Introduction, a corking mass in addition to must read for whatever UNIX user.
hostname
hostname with no options displays the machine's hostname
hostname –d displays the domain lift the machine belongs to
hostname –f displays the fully qualified host in addition to domain name
hostname –i displays the IP address for the electrical flow machine
ping
It sends packets of information to the user-defined source. If the packets are received, the goal device sends packets back. Ping tin move used for 2 purposes
1. To ensure that a network connexion tin move established.
2. Timing information every bit to the speed of the connection.
If you lot do ping www.yahoo.com it volition display its IP address. Use ctrl+C to halt the test.
ifconfig
View network configuration, it displays the electrical flow network adapter configuration. It is handy to reach upwards one's withdraw heed if you lot are getting transmit (TX) or have (RX) errors.
netstat
Most useful in addition to rattling versatile for finding a connexion to in addition to from the host. You tin detect out all the multicast groups (network) subscribed past times this host past times issuing "netstat -g"
netstat -nap | grep port will display procedure id of application which is using that port
netstat -a or netstat –all will display all connections including TCP and UDP
netstat --tcp or netstat –t will display exclusively TCP connection
netstat --udp or netstat –u will display exclusively UDP connection
netstat -g will display all multicast network subscribed past times this host.
nslookup
If you lot know the IP address it volition display hostname. To detect all the IP addresses for a given domain name, the ascendency nslookup is used. You must stimulate got a connexion to the mesh for this utility to move useful, e.g.
$ nslookup blogger.com
You tin also exercise the nslookup to convert hostname to IP Address in addition to from IP Address from the hostname.
traceroute
A handy utility to sentiment the number of hops in addition to reply fourth dimension to larn to a remote arrangement or website is traceroute. Again you lot postulate an mesh connexion to brand exercise of this tool.
finger
View user information, displays a user’s login name, existent name, in conclusion lift in addition to write status. this is pretty sometime Unix ascendency in addition to rarely used nowadays.
telnet
Connects goal host via the telnet protocol, if telnet connexion establishes on whatever port way connectivity betwixt 2 hosts is working fine.
$ telnet hostname port
will telnet hostname alongside the port specified. Normally it is used to come across whether the host is move in addition to the network connexion is fine or not.
If you lot are similar MySQL every bit your database you lot may detect my MySQL commands tutorial series useful.

Example of Networking commands inward Unix
let's come across simply about illustration of diverse networking ascendency inward Unix in addition to Linux. Some of them are quite basic e.g. ping in addition to telnet in addition to simply about are to a greater extent than powerful e.g. nslookup in addition to netstat. When you lot used these commands inward a combination of detect in addition to grep you lot tin larn anything you lot are looking for e.g. hostname, connexion endpoints, connexion condition etc.For a consummate listing of UNIX commands, you come across The Linux Command Line: Influenza A virus subtype H5N1 Complete Introduction, a corking mass in addition to must read for whatever UNIX user.
