Any idea how to use tail -f in Squid to see logging and processing on localhost?

Question

Squid is good one, also webmin. I am still new to this, can someone helping how to see the Squid progress in terminal or in webmin? I mean when we open some site its going also on squid and showing the logs that site have being hit, miss, or have in cache? Also any idea to using Squid or webmin to block the ads, websites, or keywords? Thanks.

Answer 1

Squid logs are configured by default in /var/log/squid/access.log. You can change this setting via cache_access_log in /etc/squid/squid.conf (but remember to sudo service squid restart after making the change). You could tail -f that file.

For site-blocking, I recommend using jesred, which is available in the Ubuntu archive already. You can find details on using it here: http://www.linofee.org/~jel/webtools/jesred/

See the redirect_program /usr/lib/squid/jesred example in /etc/squid/squid.conf.

You can also use squid-graph for that to view cache hits,etc etc
