I want to know that how we can chat between 2 ubuntu machines in a network.
there are many messengers but we are prohibited from using those who send the files.
any command line chat messenger for 2 ubuntu in network? or GUI will also work.
The simplest way I can think would be using netcat
try this on your own machine
in one terminal:
netcat 8080 -l
(this will be the server since we used -l to set it in listen mode)
in the other terminal:
netcat localhost 8080
(this will be the client connecting to the server)
try typing in one of the windows.
You can select any port you want for client / server, but privileged ports (below 1024) require root access on the server)
Replace localhost, on the client, with the ip / dns name of the sever you want to connect to if you want to try this over a network
