First I am new at working with networks. Most of the IT staff were downsized last year including the administrator. I am a database programmer. I like ubuntu and have an ubuntu database server. I am trying to use an ubuntu server as a squid proxy so that Windows workstations on a manufacturing floor can only go to company web sites on a whitelist. I am manually configuring the workstations to go to this proxy server. Squid3 loads okay without error messages. I know it is seeing the whitelist.txt file because I get an error if the file is not present. However SQUID will not allow any addresses to load even those in the white list. Below is my squid.conf and my whitelist.txt file. The message in the Squid log is below. The message on the browser screen confirms that squid is blocking the address. I tried the same software and configuration on ubuntu 8.04 and had the same issues. Thank you.
