I have my tor configured to listen both as a relay and a socks client, but
it never listens on these ports. lsof shows it doesn't listen at all. I
used strace to check if the sockets were ever being created and I found
they were. But later they are closed, I cannot find any reason for this.
(file descriptors 7 and 8). They are closed after some DNS lookup for my
own hostname. This is version 0.2.1.30 on arch linux.
Here is the output of strace:
