[SOLVED] Process and configuration files

Jason.nix · 11-01-2023, 04:39 AM

Hello,
I have run Tor with two configuration files and when I check the processes I see two Tor processes:

Code:

# ps -A
    PID TTY          TIME CMD
 261608 ?        00:00:32 tor
 271881 ?        01:07:30 tor

How can I find out which configuration file each of these processes belongs to?

Thank you.

probably lsof -p <pid>, or check /proc/<pid>/

Hello,
Thank you so much for your reply.
In the output of the lsof -p <pid> command, I didn't see anything about the configuration file, but from the /var/lib/tor_OpenVPN/lock line in the output, I was able to identify which configuration file this process belongs to, because I had put the DataDirectory /var/lib/tor_OpenVPN line in the Tor configuration file.

As for the proc directory, which file should I check?

Code:

# cat /proc/261608/

If you used the "-f" option to specify the conf file, it will show on the command line under 'cmdline" file of that process.

Hello,
Thank you so much for your reply.
Where should I use -f?

jayjwa · 11-15-2023, 11:56 AM

Code:

tor -f /etc/other/torrc

If you run Tor without setting the config file, it will grab /etc/tor/torrc. Seems like both your instances will grab that default value. I'm not sure how you have two running off the same config as they'd try to access/bind the same port. Is there a special reason you are using two instances? You can set multiple hidden services with one file.

Yes, I have used -f. I want to merge Tor with OpenVPN and have a Tor proxy also.

Hello,
The ps aux | grep tor command, gave me some useful information.

Thank you.
