I had this list of Linux networking commands when I was a student of Communication System Engineering. I hope it helps you in the same way.
Exclusive bonus: Download Linux networking command cheatsheet for future reference. You can print it or save it for offline viewing. This may go continually until you hit Control-C. By default, the telnet port is port Few other famous ports are: 7 — echo port, 25 — SMTP, use to send mail 79 — Finger, provides information on other users of the network Use control-] to get out of telnet. Arp: Arp is used to translate IP addresses into Ethernet addresses.
Root can add and delete arp entries. Deleting them can be useful if an arp entry is malformed or just wrong.
Arp entries explicitly added by root are permanent — they can also be by proxy. The arp table is stored in the kernel and manipulated dynamically.
Arp entries are cached and will time out and are deleted normally in 20 minutes. IP Command ip command is another useful command line utility for displaying and manipulating routing, network devices, interfaces.
It is a replacement for ifconfig and many other networking commands. The following command will show the IP address and other information about an network interface. To temporarily assign IP Address to a specific network interface eth0 , type. Ethtool Command ethtool is a command line utility for querying and modifying network interface controller parameters and device drivers. The example below shows the usage of ethtool and a command to view the parameters for the network interface.
To test connectivity to another node, simply provide its IP or host name, for example.
Traceroute Command Traceroute is a command line utility for tracing the full path from your local system to another network system. It is an easy-to-use network troubleshooting utility after ping command.
MTR Network Diagnostic Tool MTR is a modern command-line network diagnostic tool that combines the functionality of ping and traceroute into a single diagnostic tool. Its output is updated in real-time, by default until you exit the program by pressing q. The easiest way of running mtr is to provide it a host name or IP address as an argument, as follows. You can limit the number of pings to a specific value and exit mtr after those pings, using the -c flag as shown.
Route Command route is a command line utility for displaying or manipulating the IP routing table of a Linux system. It is mainly used to configure static routes to specific hosts or networks via an interface.
You can view Kernel IP routing table by typing. Here are some useful ones: Add a default gateway to the routing table. Nmcli Command Nmcli is an easy-to-use, scriptable command-line tool to report network status, manage network connections, and control the NetworkManager.
To view all your network devices, type.
