server

Install rsh-server

using rhosts

If you want to have a password-less access edit in the home directory the $HOME/.rhosts and add the nodes, from which access is allowed. Better chmod 600 . This approach works for root and user access. If you really need root access, edit the /etc/securetty and add some lines with pts/0 ... pts/n . In principle, on can use netgroups, probided by NIS or LDAP

using hosts.equiv

Another way only works for user accounts. Edit the /etc/hosts.equiv and add a line

host user .

This does not work for a root account!
