Hi LQ Community,
I am setting up a squid proxy for my organisation to replace Microsoft TMG.
The requirements are as follows:
* Must use a proxy pac file - Done
* Must authenticate via AD domain controllers - Done
* Ability to block websites - Experiencing issues.
Environment:
RHEL 6.5
Squid 3.1
I have read many guides on how to block sites and it seems simple enough but I just can't get it to work. No matter what I do it always allows all sites and doesn't block anything. Ultimately, I want to block all sites and only allow what is in the file /etc/squid/black_white_lists/allowed-sites.txt
My /etc/squid/squid.conf is below:
Code:
# Recommended minimum configuration:
#
#
# Authentication
auth_param ntlm program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp
auth_param ntlm children 10
acl auth proxy_auth REQUIRED
http_access allow auth
#
acl manager proto cache_object
acl localhost src 127.0.0.1/32 ::1
acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 ::1
# Example rule allowing access from your local networks.
# Adapt to list your (internal) IP networks from where browsing
# should be allowed
acl localnet src 10.0.0.0/8 # RFC1918 possible internal network
acl localnet src 172.16.0.0/12 # RFC1918 possible internal network
acl localnet src 192.168.0.0/16 # RFC1918 possible internal network
acl localnet src fc00::/7 # RFC 4193 local private network range
acl localnet src fe80::/10 # RFC 4291 link-local (directly plugged) machines
acl SSL_ports port 443
acl Safe_ports port 80 # http
acl Safe_ports port 21 # ftp
acl Safe_ports port 443 # https
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
acl allowed_sites url_regex "/etc/squid/black_white_lists/allowed-sites.txt"
http_access allow allowed_sites
#
# Recommended minimum Access Permission configuration:
#
# Only allow cachemgr access from localhost
http_access allow manager localhost
http_access deny manager
# Deny requests to certain unsafe ports
http_access deny !Safe_ports
# Deny CONNECT to other than secure SSL ports
http_access deny CONNECT !SSL_ports
# We strongly recommend the following be uncommented to protect innocent
# web applications running on the proxy server who think the only
# one who can access services on "localhost" is a local user
#http_access deny to_localhost
#
# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS
#
# Example rule allowing access from your local networks.
# Adapt localnet in the ACL section to list your (internal) IP networks
# from where browsing should be allowed
http_access allow localnet
http_access allow localhost
# And finally deny all other access to this proxy
http_access deny all
# Squid normally listens to port 3128
http_port 8080
# We recommend you to use at least the following line.
hierarchy_stoplist cgi-bin ?
# Uncomment and adjust the following to add a disk cache directory.
#cache_dir ufs /var/spool/squid 100 16 256
# Leave coredumps in the first cache dir
coredump_dir /var/spool/squid
# Add any of your own refresh_pattern entries above these.
refresh_pattern ^ftp: 1440 20% 10080
refresh_pattern ^gopher: 1440 0% 1440
refresh_pattern -i (/cgi-bin/|\?) 0 0% 0
refresh_pattern . 0 20% 4320
Contents of /etc/squid/black_white_lists/allowed-sites.txt (this is just for testing so far. Our current white list will be migrated once I get this working)
Code:
.access.redhat.com
.vmware.com
.mcafee.com
If anyone could shed some light on my problem it would be much appreciated.
Cheers.
