I never heard of this word rsh and also received a check list from Security pro that we have to disable rsh.

Can someone please tell me what is this rsh and how to disable it.

Base OS : RHEL 5.5 and 5.6

rsh is remote shell and it is unencrypted, that's why you should disable it.

I don't know which OS you are talking about, but for RHEL (like sr_ already stated) edit /etc/xinetd.d/rsh and set disable = yes.

After that restart xinetd and you're done.

Though I think, rsh should be disabled by default. Instead of rsh use ssh.

For more information on rsh read the man page.

To disable rsh access (on RHEL 5.11 servers) I had to do the following:

Edit /etc/xinetd.d/rlogin, and set disable = yes

And after that restart xinetd.
