I'm sorry, I've changed the event order: the correct is "- ssh-host-config
-y, rebooted;". I mean, the service was auto-started during boot, as
configured by the script.
>Can you "ping localhost"?
No problem with that (response time <1ms). It resolves "localhost" as
127.0.0.1.

Oh, nobody, I'm just considering all possibilities. This one is (was?) in
the "unplausible" list. :-)

Yes; and, as happened to you, it would complain if it doesn't like
permission settings.

This is always a point to be rechecked. I just did it:
- All ssh.exe, ssh2.exe (Windows GUI client) and sshd.exe have full
permissions set to access and server;
- Logging on, but no log entries about these programs being blocked.
Anyway, as I said before, all my tests were performed with firewall not
running. Should I try, for the sake of completeness, uninstalling it?

Nothing there. "localhost" is the only entry in /etc/hosts (which is a link
to Windows config file in C:\windows\system32\drivers\etc\hosts). Windows'
lmhosts.sam is clean.

Good point. I ran it, but got no response at all (telnet screen remains
blank). Also (just to check) it doesn't work if service is down. So,
everything is pointing towards a failure in the server side.

I was exactly thinking about using Ethereal. However, I can't go much far on
that, since I don't know nothing about the protocol. I'l see what Ethereal
has to tell me.
Again, thank you for all the help.
