I am not able to use the Tor Network,I use Debian
Linux everything well-installed,but the logs are as
above everytime,and not once I could use Tor.
So I suspect that my ISP blocks Tor.Looking at the
above logs can someone tell me what is the problem?

Note:I use tor-button with
firefox.torcheck.xenobite.eu
always tells me tor not in place,the same using
showmyip.com the IP is my ISP IP.Now in torrc I
determine entrynodes and exitnodes verified previously
if are running.
