disappearing internet connection
« on: June 25, 2005, 12:24:39 PM »
i know the problem has been discussed other times in a way or another but i can't get out of it: randomly, internet connection crashes if amule runs.
i used amule (until 2.0.1) on suse 9.1 and 9.2: never had a connection crash.
now i use amule 2.0.3 on suse 9.3 (same hardware) and i had to decrease connections/5 sec from 20 (value i always used) to 5 but still connection crashes.
modem is d-link dsl 200 and works pretty well.
clients on queue: ususlly from 200 to 400
shared files: 280 or so
files on queue:  about 60 (mostly without sources, 5 stopped)
what can i do? help please!

bye

What does it mean "connection crash" - suddently modem catch fire ? router explode ? You head strange voices ?
But - you may have faulty router.Try to connect directly. Perform exorcizm, it also helps.

I've been suffering from exactly the same problem for several weeks; internet connection seems down, but you can make pings to pages. And amule is connected to a server, but it doesn't download anything. It seems like amule collapses the tcp/ip sockets or something like this. In my case, I have a router and 3 computers, and I'm using amuled daemon from amulecvs deb package. And when you turn off amule, the connection turn back normal again.

So, limit bandwidth amuled uses and "max connections in 5sec". Also recommended to read:

http://www.amule.org/wiki/index.php/FAQ_network

Also as I say, you may have buggy router, with NAT unable to deal good with many connections.

really thanx lfroen for the serious answer you gave me.

afaik my modem has not router functions and i'm not connected via nat.

@ jabicho: no, i get disconnected. closing amule doesn't solve the problem. i have to re-run the adsl-start script to be connected again.

This is serious fault. You can start to examine OS and router logs to see what exactly caused disconnect.

Do you have real IP ? "/sbin/ifconfig" will tell you what you have. Modem with nat and router cost more. Did you buy it ? :)

here you can find two parts of my /var/log/messages: they are about two different crashes that happened in these days. i noticed that the crashes are after a too frequent Unsupported protocol 0x1 received logging; any idea?
i emailed eciadsl team but they don't know what to do about this :(

It looks like pppd can't understand what the other side send. Try google for LCP ProtRej for discussions about those issues.
Bottom line is usually that either of sides is buggy.
