FC2 Server freezes when amule starts
« on: June 04, 2005, 01:47:01 AM »
Hi mates, I have a FC2 server with many services on: samba, email, web server, FTP server ...
Everything works fine as far as I don't start amule, no matter the way I do: amule or amuled. Whenever I start it, I get my server frozen after 1 or 2 days running.

I've configure my firewall with GuardDog firewall tool and I've opened the ports the aMule web site recommends: TCP -> 4662 & UDP-> 4662:4665, 4672

More details about that at: http://www.amule.org/wiki/index.php/Firewall

However, I've realized many packets are dropped and my ip_conntrack gets bigger and bigger everytime what leads in a higher CPU overhead, although not much anyway.

Do you know what might be happening with my PC?

I've tried many things so far, although no success at all. The last thing I've tried is to launch a script which checks whether my IP has changed (I use dynamic DNS) and it such a case, it runs again the rc.firewall script GuardDog creates. It stops all the traffic, empties all chains and rewrites all rules again with the new IP.

I've thought the following snippet of my /var/log/messages log fie might help:

I installed the FC3 rpm there is in the download section, although I don't think this is the reason...

I don't get what button you mean. I've check at preferences pop-up windows and I haven't seen anything similar at all...

Well, as I said I download amule from the download section at the amule web site (aMule-2.0.1-1.i386-FC3.rpm and wxGTK-2.6.0-1.i586-FC3.rpm files).

In keeping with the searching, well, I've already done that but I didn't find anything that drew my attention. Since I use and self-configure kernel, I don't discard this might be a problem, don't know... I've attached my .config files (renamed as kernel.config.txt) just in case you want to have a look...
