Squid is web page caching proxy that holds pages, and decides for you whether or not to go back to the web server to retrieve the page, or serve it to you from its own cache. This is murder for FrontPage, and it is of dubious value on a home network, IMHO. I was having MASSIVE problems with FrontPage the morning I upgraded to 5.1.2 -- but shutting Squid off set everything right immediately.
The instructions (robbed from a previous post) are:
/sbin/e-smith/db configuration setprop squid Transparent no
/sbin/e-smith/signal-event console-save
/sbin/e-smith/expand-template /etc/rc.d/init.d/masq
/sbin/e-smith/expand-template /etc/squid/squid.conf
service masq restart
If you print them out, and key them in (in order) at the command line (logged in as root), you should have Squid out of your way with no trouble.
Good luck,
Dan
