1. Try to connect to the SSH server directly from the box running Tor, without
going through Tor. "telnet localhost 22" (assuming your sshd is using the
usual port; sometimes people map different ports when running hidden
services) will tell you if sshd is up without actually logging in.
2. Run tcpdump or wireshark on the server looking for any activity on port 22;
while it's running, try to connect to the hidden service. If tor and sshd are
on the same computer, you need to watch the loopback interface.
3. Rename the hostname file, leaving the private_key untouched, in the hidden
service folder, and restart tor. It should create an identical hostname file.
You can add "SafeLogging 0" to torrc to tell tor to show you the addresses of
hidden services it's failing to connect to. Set it to 1 when you've fixed the
tor-talk mailing list
