Instant Squid

Ever needed to test your HTTP client app proxy support? Need an instant proxy test setup? Here is a fast way to set up a local proxy server on Debian using squid:

apt-get install squid

Now edit the squid configuration /etc/squid/squid.conf.

Edit ACLs

Ensure to have something like the following:

acl all src all
acl users proxy_auth REQUIRED

Edit access definitions

You need (order is important):

http_access allow users
http_access deny all

Setup Dummy Auth

auth_param basic program /usr/local/bin/squid_dummy_auth
auth_param basic children 5
auth_param basic realm Squid proxy-caching web server
auth_param basic credentialsttl 2 hours
auth_param basic casesensitive off

Create Auth Script

Create /usr/local/bin/squid_dummy_auth with something like:


while read dummy;
   echo OK

and make it run

chmod a+x /usr/local/bin/squid_dummy_auth


Finally restart squid

/etc/init.d/squid restart

With this you have a working Basic Auth proxy test setup running on localhost:3128.
