I upgraded to SME 5.6 this weekend and applied update 5. I had lots of problems so I wiped the hard drive and installed a fresh copy of SME 5.6, then immediatly applied update 5. Later in the day I installed snort and acid and ran into problems with snort being unappy with it's rules. I also noticed squid was dropping out somewhere along the way. So I removed the broken snort install and a few hours later, squid died again.
So last night I wiped the hard drive again and did a fresh SME 5.6 install and applied update 5. The modifications from a stock install are:
Half dozen user accounts
Two iBays
Netjuke b17 installed in 1 of the iBays with about 25 gig of music
Custom template for 50localaddresses for more personal identd user names based on local ip
Added libipt_length.so to add packet length matching options to iptables
Custom template for 40AllowICMPIn to drop 92 byte icmp echo requests (NACHI worm)
New custom template for 47BlockAddresses to drop traffic from a handfull of problem ip's
After some ammount of time running, I cannot access any external web pages. I still have connectivity to irc and usenet news. When I restart squid, I get a line that stopping it failed and the next line says starting it was successfull. At that point, web access works untill squid dies again. The messages log shows occasional signal 4 and signal 6 error messages for squid but the times don't really match when web access fails. The squid logs don't show anything unusual.
Any ideas about what the problem might be ? Any clues on how to debug ? What's the latest version of squid I can upgrade to with SME 5.6 ?
