I'm not sure about dansguardian, but I'm sure that Squid can open itself up at a specific time interval for *all* users during the work day, ie: (Note that the time slot mentioned is in 24-hour format, and only a quick and dirty example) acl break_time time M T W H F 12:00-12:15 acl auth_users <auth_routine> acl blocked_sites dstdomain <...> http_access allow auth_users break_time http_access deny blocked_sites http_access allow auth_users http_access deny all Also, please make note of the use of "auth_users" ACL, assuming that this would be tied to a routine to identify your users. If this were not given, the USERNAME of the auth_users would not be logged, and it would be the _first_ occurrence of a "auth_users" lookup in the ACL ordering, but this type of ordering would be required to accomplish what you are looking for. This could also have the side effect of displaying the USERID of the person trying to visit a BLOCKED site, via Squid ACL, unless this is all handled by Dansguardian. >>> Fran MÃrquez <fjmarquez.ext@xxxxxxxxxxxxxxxxx> 4/15/2011 8:49 AM >>> Hi, I have a doubt: Can I setup squid for allow full and free access during a limited time period (for example, 15 minutes per day) for users can access to any site without restrictions? I don't like prohibit access to some popular sites, but I can't open it permanently, since this is an office and people should work, but I understand that sometimes, a relax period is useful for work better, so I'm considering leave about 15 minutes per day of free and full access. So, employees can visit his facebook profile, personal mail and others non work-related sites during shorts periods of time. Can I do this with squid and dansguardian?
