Telnet Communication Commands,While working on a Linux running machine.
you may want to speak with different devices. For this, there are a few fundamental utilities that you may employ.
These utilities permit you to talk with:
- networks,
- other Linux systems
- and remote users
So, let us learn them one by one.
- SSH
- Ping
- FTP
- Telne
Telnet Communication Commands,SSH
SSH which stands for Secure Shell, It is used to connect to a remote computer securely.
Compare to Telnet, SSH is at ease wherein the customer /server connection is authenticated using a virtual certificate and passwords are encrypted.
Hence it is broadly used by gadget directors to govern faraway Linux servers.
The syntax to log right into a far off Linux system using SSH is
SSH username@ip-address or hostname 
Once you are logged in, you could execute any commands which you do for your terminal
Example:
ls 
Example:
pwd
Telnet Communication Commands,Ping
This application is typically used to check whether or not your connection to the server is healthful or now not.This command is also used in
- Analyzing network and host connections
- Tracking network performance and managing it
- Testing hardware and software issues
Command Syntax:-
ping hostname="" or=""Example :
ping 172.16.170.1
ping google.comHere, A device has sent sixty four bytes data packets to the IP Address (172.16.One hundred seventy.1) or the Hostname(www.Google.Com).
If even one in every of records packets does now not go back or is lost.
It’d endorse an mistakes in the connection. Usually, internet connectivity is checked the use of this approach.
You may also Press Ctrl + c to exit from the ping loop.
Telnet Communication Commands,FTP
FTP is file switch protocol. It’s the most preferred protocol for facts switch amongst computers.
You can use FTP to –
- Logging in and establishing a connection with a faraway host

| put file | upload ‘file’ from local to remote computer |
| get file | Download ‘file’ from remote to local computer |
| quit | Logout |
Let us run a number of the crucial instructions.
Telnet
Telnet Communication Commands,Telnet enables to –
- connect with a remote Linux computer

The best distinction is, in case you are connected to a remote host, the commands might be achieved at the far off gadget, and no longer your local system.
You may additionally go out the telnet connection by using entering the command ‘logout’
Summary:
- Communication between Linux/UNIX and different exclusive computer systems, networks and remote customers is feasible.
- The ping command exams whether the reference to a hostname or IP-address is operating or not. Run ‘ping IP address or Hostname’ at the terminal
- FTP is favored protocol for sending and receiving massive files. You can establish an FTP connection to a far off host after which use instructions for uploading, downloading documents, checking record and browsing them
- Telnet application lets you connect with a faraway Linux computer and work on it
