This is a continuation of the problems I'm having backing up clients behind
SonicWALL firewalls to an NT4 based Legato 6.11 server.
I've updated the timeouts on the firewall to 999 minutes, and adjusted the MTU
value to 1404. I've also verified my access rules through the Legato whitepaper
on firewall access.
In the clients that are failing, I'm seeing this message repeating over and
over:
(tail /opt/networker/logs/daemon.log)

According to the server logs, the backup completes (done saving... in the admin
gui)
but never receives a final dismissal of some type, so an hour and a half later
or
so, it retries the backup again, before failing with the same problem. The
backup
tapes are full of good savesets that never recieved a "final blessing" of some
type
because the firewall broke the pipe between client and server.
Anyone?
Thank you. -Gary
