Well, thanks to the iptables --list, I found out where the restrictions came from; I have a version of guarddog firewall installed, for whatever reason, and when it installed, it used the most restrictive policies possible, so that NOTHING can come in. Since the machine is behind an NAT router, and has no ports forwarded to it from the router, and the rest of the LAN is physically secure and hard-wired, and doesn't run any servers except an ssh daemon, I don't know WHY guarddog was put on this machine. I did an apt-get to remove it, and used iptables to remove the restrictive policies. Now I have to get inet or xinet working again so sshd will kick off.... Thanks for the tip, Garrett.
