Who owns /var/log/tor logs? Can`t start tor

Question

I compiled and installed tor on minibian. All I must do now is to start tor with tor.

But all I get is

Mar 15 16:51:36.713 [notice] Tor v0.2.7.6 running on Linux with Libevent 2.0.21-stable, OpenSSL 1.0.1k and Zlib 1.2.8.

With sudo tor there's no problem and it runs smoothly but normally I don't have run tor as root. Now I don´t know how to deal with the ownership of the logs. When I do sudo chmod 777 -R /var/log/tor tor runs but then there's less security.

root@Debian:/var/log# ls -al /usr/local/bin/tor
-rwxr-xr-x 1 debian-tor adm 2091616 Mär 15 14:58 /usr/local/bin/tor

Thanx!

Success! :-D I changed the rights of the logs with chmod 660 *. This is the result:

-rw-rw---- 1 debian-tor debian-tor 25124 Mär 15 20:49 notices.log.

And the log folder /var/log/tor

drwxr-s--- 2 debian-tor debian-tor 4096 Mär 15 06:25 tor

goes like this.

Thanx!
