The Squid Proxy Server
This is a quick and dirty howto about getting Squid up und running in 5min...
What benefits one may get from using an anonymous proxy server? Well, I would say many things but the most important one is that you can browse the web anonymously without exposing your IP, location etc.. out there. Anyhow, even though I usually use OpenVPN or PPTP for safe browsing and such things, having a private anonymous proxy server in your toolbox is a nice thing. Furthermore, a cache is speeding up you daily internet connection with repeating objects getting out of the cache instead of downloading it again. Advanced filtering technics (Antivirus, Content, Ad-Blocks, etc) are also possible.
Please start always by refreshing your portage tree, like:
root # emerge --sync
next, we search the portage tree for net-proxy/squid:
root # emerge --search squid => net-analyzer/squid-graph => net-analyzer/squidsites => net-analyzer/squidview => net-proxy/squid => net-proxy/squidclamav => net-proxy/squidguard => sec-policy/selinux-squid
Next, we emerge squid using:
root # emerge net-proxy/squid
Once it is installed, since this squid proxy setup will be using authentication to authenticate users via the ‘ncsa_auth‘ helper, we need to know the location of this helper so we can use it in our squid.confconfiguration file. To find this I’ll be using a tool named as ‘qfile‘ which is shipped in ‘app-portage/portage-utils‘.
- qfile ncsa_auth
net-proxy/squid (/usr/libexec/squid/ncsa_auth)
Okay, so the auth helper is located in ‘/usr/libexec/squid/ncsa_auth’ so let’s setup Squid’s configuration file (/etc/squid/squid.conf). Make sure you change ‘XXX.XX.XX.XXX’ with your actual server’s IP address and edit anything else you want to suit your needs.
root # cp /etc/squid/squid.conf{,_orig} && \cat > /etc/squid/squid.conf <<EOF auth_param basic program /usr/libexec/squid/ncsa_auth /etc/squid/passwd auth_param basic children 5 auth_param basic realm please login? auth_param basic credentialsttl 2 hours auth_param basic casesensitive off acl ncsa_users proxy_auth REQUIRED http_access allow ncsa_users 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 acl localnet src 10.0.0.0/8 root # RFC 1918 possible internal network acl localnet src 172.16.0.0/12 root # RFC 1918 possible internal network acl localnet src 192.168.0.0/16 root # RFC 1918 possible internal network acl localnet src fc00::/7 root # RFC 4193 local private network range acl localnet src fe80::/10 root # 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 Safe_ports port 901 # SWAT acl CONNECT method CONNECT http_access allow manager localhost http_access deny manager http_access deny !Safe_ports http_access deny CONNECT !SSL_ports http_access allow localnet http_access allow localhost http_access allow localhost http_access deny all http_port 2222 coredump_dir /var/cache/squid 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 icp_access allow localnet icp_access deny all acl ip1 myip XXX.XX.XX.XXX tcp_outgoing_address XXX.XX.XX.XXX ip1 cache_mgr mail@maiwald.tk cache_mem 128 MB visible_hostname ViruSzZ maximum_object_size 20 MB cache_dir ufs /var/cache/squid 512 32 512 forwarded_for off request_header_access Allow allow all request_header_access Authorization allow all request_header_access WWW-Authenticate allow all request_header_access Proxy-Authorization allow all request_header_access Proxy-Authenticate allow all request_header_access Cache-Control allow all request_header_access Content-Encoding allow all request_header_access Content-Length allow all request_header_access Content-Type allow all request_header_access Date allow all request_header_access Expires allow all request_header_access Host allow all request_header_access If-Modified-Since allow all request_header_access Last-Modified allow all request_header_access Location allow all request_header_access Pragma allow all request_header_access Accept allow all request_header_access Accept-Charset allow all request_header_access Accept-Encoding allow all request_header_access Accept-Language allow all request_header_access Content-Language allow all request_header_access Mime-Version allow all request_header_access Retry-After allow all request_header_access Title allow all request_header_access Connection allow all request_header_access Proxy-Connection allow all request_header_access User-Agent allow all request_header_access Cookie allow all request_header_access All deny all shutdown_lifetime 3 seconds EOF
proceed with creating the ‘/etc/squid/passwd’ file and adding your user by executing:
# htpasswd -c /etc/squid/passwd your_user
You need to omit the ‘-c’ switch when adding another user to the file.
Next, do a # squid -z to create the cache directory.
Finally, restart your squid server and check if it’s actually listening using:
root # /etc/init.d/squid restart root # netstat -tunlp | grep 2222 tcp 0 0 0.0.0.0:2222 0.0.0.0:* LISTEN 482/(squid)
If you would like Squid to start with your system, execute:
root # rc-update add squid default
To test it, set your browser to use the proxy server that we just created.
