I just upgraded two Debian Etch/Sid systems the day before yesterday. Afterwards, I can no longer use ssh for remote login from one to the other. ssh was not upgraded, but some other packages were (including libc6 from sid). Now when I try a remote login, I get a message saying the connection is closed by the server. Here are the last lines of the debugging output from "ssh -vvv email@example.com":
debug3: authmethod_lookup keyboard-interactive
debug3: remaining preferred: password
debug3: authmethod_is_enabled keyboard-interactive
debug1: Next authentication method: keyboard-interactive
debug2: we sent a keyboard-interactive packet, wait for reply
Connection closed by 192.168.0.101
I have tried searching Debian bug reports, but I can't find anything. Any ideas?
