Hello @all, I am using Squid 2.5.9-10sarge2 togehter with Samba 3.0.14a-3 and realized NTLM_Auth with an w2k Domaincontroller. Every night the squid logs are parsed to user statistics with sarg: http://sarg.sourceforge.net/ First Problem: When using NTLM_AUTH and a user wants to access the internet squid first returns "Authentification required", the user then sends only his usercredential, squid again returns "Authentification required" , the user sends his user- and domaincredentials and finally can access the internet: (...) 1129272288.978 0 XXX.YYY.172.0 TCP_DENIED/407 1900 GET http://www.manager-magazin.de/img/0,1020,513338,00.jpg - NONE/- text/html 1129272288.995 4 XXX.YYY.172.0 TCP_DENIED/407 1904 GET http://www.manager-magazin.de/img/0,1020,513338,00.jpg - NONE/- text/html 1129272288.996 1 XXX.YYY.172.0 TCP_DENIED/407 1900 GET http://www.manager-magazin.de/img/0,1020,495700,00.jpg - NONE/- text/html 1129272289.008 4 XXX.YYY.172.0 TCP_DENIED/407 1904 GET http://www.manager-magazin.de/img/0,1020,495700,00.jpg - NONE/- text/html 1129272289.283 287 XXX.YYY.172.0 TCP_MISS/200 6727 GET http://www.manager-magazin.de/img/0,1020,513338,00.jpg exampleuser FIRST_UP_PARENT/XXX.YYY.172.4 image/jpeg 1129272289.293 283 XXX.YYY.172.0 TCP_MISS/200 7464 GET http://www.manager-magazin.de/img/0,1020,495700,00.jpg exampleuser FIRST_UP_PARENT/XXX.YYY.172.4 image/jpeg (...) So the syntax is this: time elapsed remotehost code/status bytes method URL rfc931 peerstatus/peerhost type Let us say the user "exampleuser" has the IP "XXX.YYY.172.66". I do not understand why XXX.YYY.172.0 is logged insted of XXX.YYY.172.66 My first thought was that the option "client_netmask" in /etc/squid/squid.conf was set in a wrong way but it is: "client_netmask 255.255.255.255" so that squid should log the whole IP, right?
