Huh, are you asking about XDM? I'm really not sure what you want to do. If you want to be able to run X programs on the other machine, and have them display on your X desktop, use ssh -X, or make forwardX11 the default for that host. If you want the window manager and everything to be running on the other machine, then I guess you want XDM, but you can't use encryption for that. > For a while, before I updated the Sid system using dselect, I at least > had ssh working both ways.

I get the message: "ssh_exchange_identification: > Connection closed by remote host" Check /etc/hosts.allow.

You should use ssh-keygen to create a keypair on each machine, and copy the public key from the machine you generated it on to the other machine. This allows quick passwordless authentication. It does only work on a per-account basis, not a machine-wide thing like hosts.equiv. (SSH does support .shosts/.rhosts, if you enable it in the config _and_ make /usr/bin/ssh (not sshd) setuid root, so it can bind to a port below 1024 (to prove that it is trusted). If you really don't care about security, you can just install rlogin. I always use ssh even on my trusted LAN at home (except for big file transfers) because one tool for everything is easier. -- #define X(x,y) x##y Peter Cordes ; e-mail: X(peter@cor , des.ca) "The gods confound the man who first found out how to distinguish the hours!
