[Veritas-bu] Networking / client issue?

This is good advice.  We actually figured out the issue to be that the
system had DNS configured but the nsswitch file wasn't updated to
include DNS in the search so it couldn't do a reverse lookup on the
master server.

Dan,

 

Can both server and client perform reverse lookups of each other? In
other words, can the client do a lookup on the master/media server by
its IP address and get an answer? Likewise, can the master/media server
do a reverse lookup on the client (by IP address) and get an answer? If
not, that is likely your problem.

Netbackup wants to be able to lookup clients both forward (by name) and
reverse (by IP address). Interestingly, netbackup doesn't care what name
actually comes back on a reverse lookup - it just wants the lookup to
succeed.

 

Hope this helps ...

I have been having an issue with one of my clients backing up getting a
54 Error.  I tried some basic network troubleshooting, like checking the
duplex, which was fine and also made sure that port 13782 is listening
on the client.  All of that seemed fine, and if I am on the client, I
noticed that I can telnet client 13782 which works fine. 

Going to the master server and telnet client 13782 gives the following 

# telnet client-host 13782 
Trying 10.10.x.x... 
Connected to client-host. 
Escape character is '^]'. 
gethostbyaddr: Error 0 
Connection to client-host closed by foreign host. 

Suggestions on what else to try? 

Thanks,
Dan
