I was just going to add that, running /etc/rc.d/rc.tor status as root gives a more "normal" answer.
But any way, do you know the meaning of
elif kill -0 $PID; then
I read so much that elif is an alternate command, to apply if the condition kill -0 $PID is present. But what does that mean? |

kill -0 $PID
indicates if a signal can be sent, meaning checking if process exist.
0 = exist
Here is an example.
Getting PID of Tor
| Code: | root@sms:~# pidof tor
27206 |
Checking for process
| Code: | root@sms:~# kill -0 27206
root@sms:~# |
Getting the state
| Code: | root@sms:~# echo $?
0 |
Now try an imaginary process like:
| Code: | root@sms:~# kill -0 272061
-bash: kill: (272061) - No such process |
And getting state
| Code: | root@sms:~# echo $?
1 |

Thank you, very much indeed!
I'd never seen "kill" being used that way before, "check if" or how I shall put it. I've used it, but only to kill processes (stop them as I earlier interpreted it)
Everyday I learn a little bit more, someday may even enough to dare install Slackware 14 all by myself 
My best regards

I've now run a Tor-node for a couple of months. Considering my upload-bandwidth it works fairly well, transmitting between 0,5-2GB/24 h.
In /var/log/tor I noticed that every night, exactly at 04:40 tor reloads?
| Code: | Apr 15 04:40:02.927 [notice] Received reload signal (hup). Reloading config and resetting internal state.
Apr 15 04:40:02.930 [notice] Tor 0.2.2.35 (git-b04388f9e7546a9f) opening new log file. |
This is no setting I've made and I cannot se any other server software restarting simultaneously?
Do you know if this "HUP"-signal comes internally from the SMS-serversoftware, or perhaps could come from some Tor-networkcontrol?
Best regards

That sound like a logrotate
/etc/logrotate.d/tor
| Code: | /var/log/tor/*log {
daily
rotate 5
compress
delaycompress
missingok
notifempty
create 0644 tor tor
sharedscripts
postrotate
/etc/rc.d/rc.tor reload > /dev/null
endscript
} |
