This guide contains some useful information about the Squid system in ClearOS. This guide can be used for command line queries or as a template for the development of reporting features for squid.
The access file for squid is useful for troubleshooting and proving authentications, hits from clients and other useful info:
tail -f /var/log/squid/access.log
To watch a specific IP address (i.e. 192.168.1.123):
tail -f /var/log/squid/access.log |grep 192.168.1.123
The error log is also useful for watching for errors in the web proxy's handling of pages:
tail -f /var/log/squid/error.log
To see the running configuration for squid type the following from command line:
squidclient -h 127.0.0.1 mgr:info
