RE: [squid-users] CONNECT issues

Dear all,

 Sorry for late reply. After further tracking, i
managed to re-check the squid configuration files and
below are the acls list :-

acl SSL_ports port 443 563
acl Safe_ports port 80 # http
acl Safe_ports port 21 # ftp
acl Safe_ports port 443 563 # https, snews
acl Safe_ports port 70 # gopher
acl Safe_ports port 210 # wais
acl Safe_ports port 1025-65535 # unregistered ports
acl Safe_ports port 280 # http-mgmt
acl Safe_ports port 488 # gss-http
acl Safe_ports port 591 # filemaker
acl Safe_ports port 777 # multiling http
acl CONNECT method CONNECT

http_access deny Bad_Domains
http_access deny Bad_Ports
http_access deny !Safe_ports
http_access deny CONNECT !SSL_ports
http_access allow localhost
http_access allow our_networks
http_access allow manager localhost

I purposely did not include the bad_domains acl
because it is kinda long and would eventually messed
up when i posted up in the mailing list. I can
confirmed that the acl is correct anyway.

After restart squid, i viewed the access.log files to
watch out for CONNECT strings. Well, this time, it is
different though. There are no more TCP_MISS:DIRECT at
the end of the log, instead, i got TCP:DENIED. Does
this mean i am successfully block those p2p or
tunneling softwares?
