The most commonly used network commands in Linux and Unix systems

                  Undoubtedly, Linux and Unix are the most powerful command line operating systems. Although we can also use the graphical user interface (GUI) of these operating systems, the command line utilities still play a very important role when it comes to managing system configuration. It can be said that when it comes to network problems, Linux and Unix are the safest choices because their network functions are tightly integrated with the operating system and there are many tools that can be used to manage it. 1.ftp: Transfer files to another host (not very secure). 2.host: Get information about the network host. 3.ifconfig: Display IP address information. 4.netstat: Display routing information and network statistics. 5.ip: Display IP address information. 6. ping: Send an answer request to other hosts. 7.rdesktop: Display the MS Windows desktop on the Linux Machine. 8.route: Display routing information. 9.scp: Secures copying files from the host or copying files to the host. 10.ssh: Establish an encrypted link to another host. 11.sftp: Securely perform ftp transfers. 12.ssh-keygen: Generate SSH encryption key 13. telnet: Establish an insecure connection with another host. 14.tracepath/traceroute: Displays the route that the packet has passed to the destination host. 15.whois: Get information about a domain name. 16.xclock: The X Window Clock application for testing remote displays. 17.xhost: X Window Access Control Tool.
