Squid proxy server

In the Squid setup file "squid.conf" go to the section called "access control". It is well documented as to what to do. Here is a simple config to allow only PCs on the 192.168.1.0 network access to squid.

acl userlist1 src 192.168.1.0/24
http_access allow userlist1

To add an individual PC at say 192.168.6.3 but deny the rest of the segment

acl userlist2 src 192.168.6.0/24
acl user src 192.168.6.3
http_access allow user !userlist2

You can also block ports and protocols.
I hopethis helps.

Hi,

Here you have an other option so you can use to check users with an external program.

# TAG: authenticate_program
# Specify the command for the external authenticator. Such a
# program reads a line containing "username password" and replies
# "OK" or "ERR" in an endless loop. If you use an authenticator,
# make sure you have 1 acl of type proxy_auth. By default, the
# authenticator_program is not used.
#
# If you want to use the traditional proxy authentication,
# jumpover to the ../auth_modules/NCSA directory and
# type:
# % make
# % make install
#
# Then, set this line to something like
#
# authenticate_program /usr/bin/ncsa_auth /usr/etc/passwd
#
#authenticate_program none

this is from squid.conf file, so now you can find several authenticate programs i.e. for windoze smb_auth (via samba port).
