I need to exclude a couple of web sites from access by anyone on a network. I realise I could use the dansguardian or squidguard contribs, but would like to do it in a simple way initially.
I tried adding
127.0.0.1
www.ebay.com to the /etc/hosts
file, but it does not seem to effect the workstations (although the server itself can no longer access the site).
I guess the answer is related to the dnscache, about which I know very little, anyone any good ideas?
