I have a whitelist to allow users to access only sites required. We primarily use it for ftp, either through a web browser or filezilla-like clients. The browser based is flawless, but odd behavior with ftp clients. acl whitelist dstdomain "/etc/squid3/whitelist" http_access deny !whitelist Whitelist contains (for testing): gatekeeper.dec.com Here is the result: 1311886691.258 21738 192.168.100.194 TCP_MISS/200 998 CONNECT gatekeeper.dec.com:21 - DIRECT/192.6.29.21 - 1311886757.392 0 192.168.100.194 TCP_DENIED/403 1899 CONNECT 192.6.29.21:51967 - NONE/- text/html As you can see, it changes from using hostname to IP address, which matches nothing in the whitelist, and is denied. If I add the IP to the whitelist, it works perfectly. How can I force it to always use the hostname?
