A bit of Unix sysadmin lore that isn't as widely advertised as it once
was (because, thankfully, it comes up far less often than it used to):
there are only three reasons why a process would remain in an
uninterruptible sleep for more than a few milliseconds: an abnormally
slow storage peripheral (e.g. a tape drive being rewound, or a hard
drive that's about to fail), a network file server that isn't
responding to messages, or a kernel bug.

Dear all,
I want to setup my machine as a tor relay. I am using Ubuntu 16.04 LTS on
a Intel i5 processor with 4 GB of memory.
I followed the instructions given on this link
<https://trac.torproject.org/projects/tor/wiki/TorRelayGuide>, but was
getting some issue. In one of the later steps, it says "Verify that your
relay works". This is done by checking my logfile(syslog) contains the
following text:

"Self-testing indicates your ORPort is reachable from the outside.
Excellent. Publishing server descriptor."

I checked the syslog by the command:

$ cat /var/log/syslog

To bring it to your knowledge, I have followed all the previous steps
mentioned on that link
<https://trac.torproject.org/projects/tor/wiki/TorRelayGuide>, and was
successfully able to execute all the commands. I would request you to
please help me out in setting up my machine as a relay to make tor network
faster and more usable.

Thank you,
Yash Kumar

Hi,

first of all: Thanks for your efforts.

Although you didn't actually mention it, I'll assume that you didn't find the
"Self-testing" line in /var/log/syslog. Is that correct? If so, please check
first whether Tor has started at all by running the following command:

$ sudo systemctl status tor

Please copy the output of that command.

Alternatively, maybe also the following happened to you when you wanted to
check whether your relay works:

$ cat /var/log/syslog
cat: /var/log/syslog: Permission denied

If that's the case, please retry with:

$ sudo cat /var/log/syslog

If I didn't cover your problem here, please be more specific in what actually
doesn't work.
