Unlike many other versions, MagniComp RDist does not need to be setuid "root" at all. RDist now uses rsh(1c) (remote command) or ssh(1) program to make connections to remote hosts, instead of making the connection directly. This eliminates the need to be run as "root"*.
One of the transports that can be used with MagniComp RDist is SSH. When used with SSH (see the rdist(1) man page) RDist can perform secure and encrypted updates. If your SSH is compiled with SOCKS support, RDist can perform secure and encrypted updates through SOCKS compliant firewall systems.
