4.4. Can I use rdist with ssh?
Stock rdist 6.1.0 does not work together with ssh, due to bugs in it.
The 6.1.1 versions of rdist and later versions are believed to work.
If you use rdist, don't forget to compile the path to ssh into it.
Alternatively, you may specify the -P option so rdist uses ssh, and
not rsh.
If you use password authentication with rdist 6.1.2 or 6.1.3, you will
need to apply the following patch to rdist to make it work:

+ if (dup2(sp[1], 0) < 0 || dup2(0,1) < 0) {
error("dup2 failed: %s.", SYSERR);
_exit(255);
}
This also applies if you get a "Warning: Denied agent forwarding
because the other end has too old version." error (which occurs if
your client is 1.2.17 or later, and it connects to an older server).
Another alternative would be to use rsync, a rdist replacement, which
was designed to work with ssh, and makes better use of bandwidth. More
information can be found at ftp://samba.anu.edu.au/pub/rsync or
