Squid3 simple proxy setup
I have set up Hardy to use as a little proxy server with a white list for a few Windows kiosks that are located in an unwatched area of a plant. I have no choice about the Windows part. I do not need a DHCP server or a firewall just a simple proxy.
I followed the instructions from 2 blogs. The proxy is working but not the way I need it to. The white list file is loaded but ignored and https:// sites that are not on the white list load. The blog posts are here
My squid.conf file is below. Most of it is the default settings that came with Squid3.
Code:
#Recommended minimum configuration:

Re: Squid3 simple proxy setup
This worked for me...thanks!
Re: Squid3 simple proxy setup
I am on a network that uses proxy with authentication scheme.
Can anyone help me edit the conf file.
When I tried installing squid in Ubuntu 12.04, it automatically installed squid, squid3 and squid-common.
so let me know how to edit its conf file.
Thank you in advance.
