I would greatly apreciate your help I have a squid configured by a previous worker and I'm starting to trying to understand some stuff here. But my current and biggest problem is that most of our wsus clients are unable to update. when i look at the squid access log, i see lots of denied requests lik this ones: 1161089442.404 7 10.0.100.122 TCP_DENIED/407 1820 POST http://wsus/SimpleAuthWebService/SimpleAuth.asmx - NONE/- text/html 1161089423.686 0 10.0.100.141 TCP_DENIED/407 419 HEAD http://wsus/iuident.cab? - NONE/- text/html what i guess that it is happening is that since many of these users do not have internet acces their requests are beeing denied at the proxy. But when i try to configure direct access to the wsus server on squid.conf, nothing changes! I've tried: acl wsus_allow src 10.0.160.60 #(160.60 is the ip of wsus server) http_access allow wsus_allow and acl wsus dstdomain .local.lan #(the local domain) http_access allow wsus and acl wsus dstdomain .local.lan #(the local domain) always_direct allow wsus can anyone advise me please? Im I dooing this correctly? thank you! using Centos and Squid Version 2.5.STABLE6
