[SOLVED] Squid ACL To Block All the Sites And Allow Only Permitted

[amithad]

Hi,

I'm Using Squid squid-3.1.10-9.el6_3.x86_64 version.

I want to block all the web sites and allow only some permitted sites. I tried configuring squid but when deny the localnet for http_access I can't access any site. My squid config is as follows


----------------------------------------------------------

#
# Recommended minimum configuration:
#
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 192.168.101.0/24 # 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

#
# 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 localnet
http_access allow localhost

# And finally deny all other access to this proxy
http_access deny all
# http_access allow all
# Squid normally listens to port 3128
http_port 3128

# 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

acl AllowSites url_regex "/etc/squid/allowed-sites"
acl business_hours time 14:00-17:00
http_access allow localnet AllowSites business_hours
# Leave coredumps in the first cache dir
coredump_dir /var/spool/squid
visible_hostname [proxy.server]
# 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

Hi,

Finally was able to search the net and after some trial and error basis experiments was able to get the thing worked

My configurations are as follows

acl groupA src 192.168.101.253 192.168.101.60
acl groupB src 192.168.101.27 192.168.101.41
acl business_hrs time 11:00-17:00
acl AllowedSites dstdomain Google Wiki: Welcome Visitors
http_access allow localnet business_hrs AllowedSites groupB
http_access deny all

Now I'm trying to customize my error pages
