tor hidden SSH service worked briefly.
Unfortunately, I am getting the same error I got before:
Tor starts fine with:
"Starting tor: Sep 20 20:41:00.014 [notice] Tor v0.2.2.33
This is experimental software. Do not rely on it for strong anonymity.
(Running on Linux x86_64)

/usr/bin/torctl start: tor started"
After a few seconds, I check via "service tor status", and get:
"PID file (/var/run/tor/tor.pid) present, but tor (29865) not running"
I edited torrc to log errors, warnings, and notices, there are no
abnormalities logged... it seems that tor just stopped. This has been
happening in the past, and is still happening now after the recent
update to Tor v0.2.2.33. "service tor restart", nor complete system
BTW, I am running Scientific Linux 6.1, and used "yum install tor"
from the following repo:
name=Tor and Vidalia
Can anyone help with this? I can't even begin testing the hidden
service before getting tor running first..... and this problem has
been bugging for the past two months... Thanks.
