I wanted to try out rsh (or rshell?) - the old, insecure way of logging in remotely.

On my Ubuntu 11.04, it turns out an rsh command exists:

$ which rsh

/usr/bin/rsh

... however, it turns out it is a mere symlink for ssh:

$ ls -la `which rsh`

lrwxrwxrwx 1 root root 21 2011-03-25 16:07 /usr/bin/rsh -> /etc/alternatives/rsh



$ ls -la $(readlink -f `which rsh`)

-rwxr-xr-x 1 root root 391580 2011-04-02 12:16 /usr/bin/ssh

Does this "old" rsh exist in Ubuntu repositories - and if so, how do I install it? Also, is rsh also split in client and server packages - and if so, which packages are those?
