We're using squid 2.2.stable5 as proxy on a SuSE 7.0 box and i would like ALL users to go through the proxy... I know we have some users that play with internet and disable their proxy parameters.... how can I ban "direct internet access" so only proxy connections pass through (whatever is configure on users win stations) ? -- _____________________________ /"\ Markus Gaugusch ICQ 11374583 \ / ASCII Ribbon Campaign markus@gaugusch.dhs.org X Against HTML Mail / \
