I have two Debian systems behind a Linksys router, with the router blocking everything except returning packets. One system is debian "stable" (Woody), the other "unstable" (Sid). I have read through just about all the PAM docs and the Debian Security Docs, but still haven't been able to find out how to make Sid allow Woody, for example, start an X session as a remote host - I have tried all the ideas that were given.
For a while, before I updated the Sid system using dselect, I at least had ssh working both ways. But now I can only ssh to Woody from Sid; not the other direction. I've checked all the config files and can't find where it is stopping. I get the message: "ssh_exchange_identification: Connection closed by remote host" I would really like these two systems to trust each other with just the "host.equiv" and .rhosts files set, even though that is unsafe on a system exposed to the world. But for the type work I am doing, that is not a problem. Thanks for any ideas. Boyd KO4WK Zech 4:6
