Keeping track of such 'blockings' you've done all over the place (at the DNS, proxy and firewall) will eventually get tedious. regards, -Suraj -- Career Gear - Industry Driven Talent Factory http://careergear.in/ ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc

Did you check out the following page ? http://wiki.squid-cache.org/Features/HTTPS#CONNECT_tunnel Since, its a tunnel, you can probably restrict access only by denying domain names instead of urls and such. you should try the following and see if it works, http://wiki.squid-cache.org/SquidFaq/SquidAcl#Squid_doesn.27t_match_my_subdomains -- 0 ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc

This is a clumsy and often unworkable solution. 1. It has to be done on each individual client machine using the squid proxy. 2. It has to be constantly updated on each machine. 3. And every browser on said client machine must be configured NOT TO use the proxy for such banned domains. Very clumsy. There has to be a more elegant way. ...KRS ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc

If your gateway does NAT, I presume you are using squid as a transparent proxy. If the gateway does not NAT, then the clients cannot reach the Internet except thro' a proxy server like squid via an explicit proxy configuration in the browser. If this is the case, shouid should be able to control access to these sites. If NAT is enabled, then you'll need to redirect DNS requests to a local DNS server which either denies access by dropping those requests. -- Mohan Sundaram ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
