(This also causes the strange behavior of a clients 'netstat -an |grep 5222' command saying "ESTABLISHED" even though there is no connection on the spacewalk server.) After doing the following, I am having no issues with timeouts... <PRE> ---------------------- sed -i 's/<interval>.*/<interval>120<\/interval>/' /etc/jabberd/*.xml* sed -i 's/<keepalive>.*/<keepalive>120<\/keepalive>/' /etc/jabberd/*.xml* sed -i 's/<idle>.*/<idle>600<\/idle>/' /etc/jabberd/*.xml* |grep '<idle>' rhn-satellite restart Restarted osad on all clients (This step may not be necessary.) ---------------------- </PRE> The above settings are all explained in the .xml configs under /etc/jabberd/ . Essentially, it will send a "whitespace" character as a keepalive. (Every 2 minutes in my case) I verified this in tcpdump and jabber does only send 1 small packet every 2 minutes. Of course depending on your firewall timeout configs, you may need to tweak this a bit. Hope this helps someone else. -Josh On Fri, 2009-11-27 at 14:52 -0500, Mullis, Josh (CCI-Atlanta) wrote: <BLOCKQUOTE TYPE=CITE> Thanks guys. Appreciate the info. I think this issue has to do with the clients being across multiple routers and possible network blips. I have no issues with clients on the same subnet. <HR> From: spacewalk-list-bounces@redhat.com To: spacewalk-list@redhat.com Sent: Thu Nov 26 08:13:13 2009 Subject: Re: [Spacewalk-list] question about jabber server and osad clients I don't know if it's a know bug, but I do know that this behavior was seen in both RHN4.x and RHN5.x . There are 2 ways you can deal with this: - cron job that restarts the osad daemon at X interval. - cron job that checks if the osad daemon is connected to it's server and restarts it when not.... I don't have the script for the second solution, but I remember it to be quiet easy (40 lines or so). One thing to know is that you need to check if the osad daemon is enabled or not, otherwise you might end up in starting a lot of osad daemons where you don't want them. regards Jouk On Thu, Nov 26, 2009 at 1:57 PM, Colin Coe <<A HREF="mailto:colin.coe@gmail.com">colin.coe@gmail.com</A>> wrote: <BLOCKQUOTE> I saw this behavior in Satellite v5.1 at a previous client site...
