What's the difference between 'rsh' and 'rlogin' ??

i know they are two separate commands, but is one simple an alias for the other? ...or is something deeper happening?

rsh is a remote shell
rlogin is remote login

So if you run rsh <hostname> it will be the same as an rlogin <hostname>

Difference is you can send commands to the host by activating a shell with rsh

ie. rsh <hostname> date


Should return the output of the date command on the host you specified.

:D

gotcha...

so in theory, running

CODE

rsh <hostname> /bin/sh

is the same as running

CODE

rlogin <hostname>

right??

i know it's be kinda pointless to do that, but it's true... i think.

No that's not only the difference:

RSH
Through rsh you can only invoke the remote shell and run command. Once your command is executed the shell is closed and connection lost.

RLOGIN
It is the remote login. once you logged in your session will start, the session lasts as long as you didnot exit from the login. So you can invoke multiple shells and execute multiple commands at the remote prompt.


I think this is the major diff
