Hi, We have a squid/dansguardian configuration here, under debian 2.6.32. The Debian distribution do not have any version of squid greater than 3.1.6. So I took squid's 3.1.23 sources and build it (successfully), using the same ./configure options than current squid3 -v give. We also use ntlm_auth and wbinfo.pl to authenticate users. My question: can I simply: -stop SQUID3/dansguardian -swap binary (/usr/sbin/squid3) with the new version -start SQUID3/dansguardian ? Is there something to put somewhere else ? Helpers ? Will it work like that ? If something fail, can I simply get the old squid3(.1.6) binary ? Furthermore, upgrading from 3.1 to 3.2 (and may be 3.3) is a difficult task ? Is it worth ?
