Squid

= HOW TO SETUP PROXY SERVER WITH SQUID IN FUNTOO

Fist thing I’ve done was refreshing my portage tree, by running:

1. emerge --sync

then I’ve searched the portage tree for ‘squid’ using my pkgfile function and got this:

1. pkgfile squid => net-analyzer/squid-graph => net-analyzer/squidsites => net-analyzer/squidview => net-proxy/squid => net-proxy/squidclamav => net-proxy/squidguard => sec-policy/selinux-squid

ok, then emerged ‘net-proxy/squid’ using:

1. emerge -av net-proxy/squid

once it got 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‘.

1. qfile ncsa_authnet-proxy/squid (/usr/libexec/squid/ncsa_auth)

ok, 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.

1. cp /etc/squid/squid.conf{,_orig} && \cat > /etc/squid/squid.conf <<EOFauth_param basic program /usr/libexec/squid/ncsa_auth /etc/squid/passwdauth_param basic children 5auth_param basic realm please login?auth_param basic credentialsttl 2 hoursauth_param basic casesensitive off acl ncsa_users proxy_auth REQUIREDhttp_access allow ncsa_usersacl manager proto cache_objectacl localhost src 127.0.0.1/32 ::1acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 ::1acl localnet src 10.0.0.0/8 # RFC1918 possible internal networkacl localnet src 172.16.0.0/12 # RFC1918 possible internal networkacl localnet src 192.168.0.0/16 # RFC1918 possible internal networkacl localnet src fc00::/7 # RFC 4193 local private network rangeacl localnet src fe80::/10 # RFC 4291 link-local (directly plugged) machinesacl SSL_ports port 443acl Safe_ports port 80 # httpacl Safe_ports port 21 # ftpacl Safe_ports port 443 # httpsacl Safe_ports port 70 # gopheracl Safe_ports port 210 # waisacl Safe_ports port 1025-65535 # unregistered portsacl Safe_ports port 280 # http-mgmtacl Safe_ports port 488 # gss-httpacl Safe_ports port 591 # filemakeracl Safe_ports port 777 # multiling httpacl Safe_ports port 901 # SWATacl CONNECT method CONNECThttp_access allow manager localhosthttp_access deny managerhttp_access deny !Safe_portshttp_access deny CONNECT !SSL_portshttp_access allow localnethttp_access allow localhosthttp_access allow localhosthttp_access deny allhttp_port 2222coredump_dir /var/cache/squidrefresh_pattern ^ftp: 1440 20% 10080refresh_pattern ^gopher: 1440 0% 1440refresh_pattern -i (/cgi-bin/|\?) 0 0% 0refresh_pattern . 0 20% 4320 icp_access allow localneticp_access deny allacl ip1 myip XXX.XX.XX.XXXtcp_outgoing_address XXX.XX.XX.XXX ip1cache_mgr wMaster@stavrovski.netcache_mem 64 MBvisible_hostname ViruSzZmaximum_object_size 10 MB forwarded_for offrequest_header_access Allow allow allrequest_header_access Authorization allow allrequest_header_access WWW-Authenticate allow allrequest_header_access Proxy-Authorization allow allrequest_header_access Proxy-Authenticate allow allrequest_header_access Cache-Control allow allrequest_header_access Content-Encoding allow allrequest_header_access Content-Length allow allrequest_header_access Content-Type allow allrequest_header_access Date allow allrequest_header_access Expires allow allrequest_header_access Host allow allrequest_header_access If-Modified-Since allow allrequest_header_access Last-Modified allow allrequest_header_access Location allow allrequest_header_access Pragma allow allrequest_header_access Accept allow allrequest_header_access Accept-Charset allow allrequest_header_access Accept-Encoding allow allrequest_header_access Accept-Language allow allrequest_header_access Content-Language allow allrequest_header_access Mime-Version allow allrequest_header_access Retry-After allow allrequest_header_access Title allow allrequest_header_access Connection allow allrequest_header_access Proxy-Connection allow allrequest_header_access User-Agent allow allrequest_header_access Cookie allow allrequest_header_access All deny all shutdown_lifetime 3 secondsEOF

proceed with creating the ‘/etc/squid/passwd’ file and adding your user by executing:

1. htpasswd -c /etc/squid/passwd your_user

(note that you need to omit the ‘-c’ switch when adding another user to the file) Finally, restart your squid server and check if it’s actually listening using:

1. /etc/init.d/squid restart # netstat -tunlp | grep 2222tcp 0 0 0.0.0.0:2222 0.0.0.0:* LISTEN 482/(squid)

if you like it to start on your system’s start-up, then you can execute:

1. rc-update add squid default

To test it, for example I use Opera for this so I just go to ‘Settings → Preferences → Advanced → Network → Proxy Servers’ and set the browser to use the proxy server we just created.
