Re: [Veritas-bu] Reducing Netbackup reserved ports on the master server

Although be careful: there is/was a bug (feature?) in NBU which may prevent you from performing synthetic full backups across a firewall. The firewalled client makes a call back to the master server on a random port. This wasn't documented when we originally ran into this problem. Not sure if it's been fixed yet.

Why not use vnetd. If it is 6.0 or above a 6.0 client and server use port 13724
( vnetd ) to communicate. In 5.1 you have to configure it.

Hi!

 

Anyone know what the impact of reducing the number of reserved ports on
at netbackup master server is?

 

The Default is 512-1023..... If we reduce it to ie. 512-600.... Will
that mean that we get lesser bandwidth for clients? This customer has
about 60 NBU clients.

 

The reason for this question is that this is going thru a firewall and
the customer  wants as few ports open as possible.
