Can anyone advise the best up to date way of filtering activex/java/javascript in conjunction with Squid and Dansguardian I am using squid-2.5.STABLE6 on Centos 4. I have been trawling the mail archives and the web and have come across a few possible solutions but would like to ask how other people are doing this in a production environment and if some of the solutions below are still valid. Firstly, in case im making this more difficult than it need's to be, is it possible to filter out the dangerous content in squid alone. I notice within the squid.conf there is a rule that deny's javascript, but is it possible use a similar rule to stop activex. The squid FAQ http://www.squid-cache.org/Doc/FAQ/FAQ-4.html#ss4.16 references http-gw which can filter the required content. Is this a recommend way of filtering content? The website for fwtk does not seem to be very up to date. Squid filter modules http://sites.inka.de/sites/bigred/devel/squid-filter.html has modules to filter content. Is anyone using these? I have tried to follow the instructions to patch/compile but receive the below errors when running the aclocal command as per the instructions. acinclude.m4:10: warning: underquoted definition of AC_CHECK_SIZEOF_SYSTYPE run info '(automake)Extending aclocal' or see http://sources.redhat.com/automake/automake.html#Extending-aclocal acinclude.m4:49: warning: underquoted definition of AC_CHECK_SYSTYPE configure.in:2420: error: `filters/Makefile' is already registered with AC_CONFIG_FILES. autoconf/status.m4:848: AC_CONFIG_FILES is expanded from... configure.in:2420: the top level autom4te: /usr/bin/m4 failed with exit status: 1 aclocal: autom4te failed with exit status: 1 Is there any other open source solutions available that I have not seen? Thanks in advance. Dean Plant
