Configuring RSH without Password

Tried on RHEL and Oracle Linux:

[1] Install rsh-server*.rpm from the Linux distribution for your system or using yum.

[2] Add the following to /etc/securetty:
rsh
rexec
rlogin

[3] Edit the rsh, rexec, and rlogin files in /etc/xinetd.d/ and change value of disable from yes to no

[4] /etc/init/d/xinetd restart

[5] Add list of hosts to /etc/hosts as:


[6] Add the hosts to ~/.rhosts as:


[7] chmod 600 ~/.rhosts
Also, ensure .rhosts is owned by the right user:group. Otherwise use chown as well.

[8] Repeat steps 1 to 7 on all hosts

Now, you should be able to rsh among the hosts on which you have setup rsh-server correctly.
