Internet access only during normal business hours using squid

Using the excellent access control features of Squid, you may configure use of Internet services proxied by Squid to be available only during normal business hours. For example, we’ll illustrate access by employees of a business which is operating between 9:00AM and 5:00PM, Monday through Friday, and which uses the 10.1.42.0/42 subnetwork:

Add the following to the bottom of the ACL section of your /etc/squid/squid.conf file:

acl biz_network src 10.1.42.0/24
acl biz_hours time M T W T F 9:00-17:00

Then, add the following to the top of the http_access section of your /etc/squid/squid.conf file:

http_access allow biz_network biz_hours
