AHA! Client disconnects occuring at exact periods...

[drominore]

Current system:

RHL8. One server running sc_serv, one running sc_trans_linux. Issue is one of clients being dropped from stream, whether usins Winamp, Media player, or Realplayer. Oddly enough, the drops occur within one second of a connect error to yp, AND the disconnect time is an EXACT multiple of 190 seconds. I have heard that this behavior is NOT occuring on Winamp2, just v3 & 5. It is somewhat random, so difficult to diagnose. Different client locations, equip, etc.

Any ideas? the broadcaster is on a DMZ at the source, but this issue looks to be a client side prob staying connected. I'd like to set the streamer to nonpublic, as the fw wont allow connection to yp on that segment anyhow. Could the streamer attempt at connecting be hiccupping the client connections?

Current settings are 32 max users, cap at 32k/2ch/22100.

Please post the DNASs log section corresponding to the error(s)/disconnect(s).

Caught me! posted before I left the house this morn and was gonna do log extracts as soon as I got in... Ok, lemme dig up the goodies...

Network Architecture: Checkpoint FW1 firewall. The Broadcast station is located on the DMZ, the capture (DSP) located on the interior network. The DMZ allows direct access to the stream from both inside & outside links. The stream capture is set to only allow specific port traffic to the DMZ for rebroadcast.

Whats got me bugged is the [yp_add] error occuring exactly 1 second before the disconnect, and the fact that the connect times are almost always a multiple of 190 seconds...

Interestingly, heres a log extract:

The IP's have been hidden but are representative of the connections; i.e. all 1.1.1.1 came from the same IP just not 1.1.1.1! :-)

Any help would be appreciated!

New Info!! The problem is still there BUT, I've been studying the logs, and interestingly enough this error:

<03/12/04@11:17:08> [yp_add] error connecting to yp.shoutcast.com
<03/12/04@11:20:18> [yp_add] error connecting to yp.shoutcast.com

<03/12/04@11:29:48> [yp_add] error connecting to yp.shoutcast.com


Is occuring almost EXACTLY every 3 mins 10 sec. This works out to 190 seconds, which is exactly the base multiplier for the drop cycles... Aha! The game is afoot, Watson...

I've set the public flag in the sc_serv.conf file to be NEVER, and the stream shoudl also be set to do not advertise. So where exactly is this error coming from and what parameters are controlling it? Short of putting in an entry in the resolv.conf file to direct this elsewhere, I can't figure how to prevent it...

I am having the SAME EXACT PROBLEM. If you figure out what's causing this, can you PLEASE post it???

Thanks!!!!!
