Re: [Networker] connection reset errors, keepalive registry tweak.

Hi,
The thing to remember about the way NetWorker sends data from the
client to the server is that it is a form of FTP. There is a control
connection and a data connection. It is likely the control connection
that is timing out because there is absolutely no traffic on that
connection while the saveset is being sent to the backup server on the
data connection.
I've had to apply keepalive changes to my solaris and linux servers (I
haven't had to modify any clients) so their control connections do not
die during those backups that take hours.

Hi.
We're dealing with a problem backing up big files over 100mb Cisco VPN
tunnel (encripted). We get "Connection reset by peer" when doing a manual
backup from the client after the backup has been running for 10hours. The
file is 100GB.
EMC is telling us to tweak the registry on the Backup server and the client
(both Server 2003 SP2, Legato 7.4.2), as per:
https://solutions.emc.com/nsepn/webapps/stqv768481dmts46655278/emcsolutionvi
ew.asp?id=esg60759
That is create this key for both the client and ther server
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\keepal
ivetime
and specify for how many m seconds to keep idle session alive.
What I'm wonderig about is whether this could affect something else on the
client (Exchange 2007) in a negative way? Or is it a safe operation with
security in mind?
How are you troubleshooting timeout problems? Any utilities that are useful?
