Some of the popular networking commands in Unix that we use are as follows:
- ping: We use this command to test the reachability of a host on an Internet Protocol (IP) network.
- telnet: This is another useful command to access another machine on the network. This is command uses Telnet protocol.
- tracert: This is short for Traceroute. It is a diagnostic command to display the route and transit delays of packets across Internet Protocol.
- ftp: We use ftp commands to transfer files over the network. ftp uses File Transfer Protocol.
- su: This unix command is used to execute commands with the privileges of another user. It is also known as switch user, substitute user.
- ssh: This is a secure command that is preferred over Telnet for connecting to another machine. It creates a secure channel over an unsecured network. It uses cryptographic protocol to make the communication secure.
