Hi there, There is a some of net ranges (computer classes) which should have internet access in some time and date. I try to find the ways to get squid net range. After that squid should give it without any authorization. I think it may look like this: My App (time/date sheduler) | | Autogenerated external file one time per day like this I think: -------------- acl class1_time time MTWHFAS 01:00-02:59 acl class2_time time MTWHF 02:00-05:59 acl class1_net src 192.168.1.0/24 acl class2_net src 192.168.2.0/24 http_access allow class1_net class1_time http_access allow class2_net class2_time -------------- | | Squid There is some quiestions: I don't want much to use the squid reconfigure method How can I dynamic connect this acl to squid. If don't, how it's better to solve this task? :)
