backup failed giving error 48

Did you follow any of the recommendations in the Troubleshhoter?

# bperror -S 48 -r
client hostname could not be found
The system function gethostbyname() failed to find the client's host name.

Verify that the client name is correct in the following:
*
* The NetBackup policy configuration on the master server.
* The General tab in the following dialog boxes: NetBackup Client Properties and Specify NetBackup Machines and Policy Type (on Micr
osoft Windows and NetWare nontarget clients). To display these dialog boxes, start the Backup, Archive, and Restore interface on the
 client. For the General tab, click NetBackup Client Properties on the File menu; click Specify NetBackup Machines and Policy Type o
n the File menu.
* The bp.conf file on UNIX, Linux, and Macintosh clients.
* The bp.ini file on NetWare target clients.
* On clients and servers, verify that the name service is set up to resolve the NetBackup client names correctly.
On UNIX and Linux clients, verify that the client's host name is in the /etc/hosts file or the YP hosts file or NIS maps.

Would be even more grateful if you marked my post as the solution instead of your own tho'!

This would enable other with the same issue to go straight to the solution by clicking on the "green tick" in the forum list or the "see solution" link on the opening post. Plus it'll give me that nice warm glow (& a few extra points!)

Whilst I've got your attention, did you get the information you needed on the following two discussions?
Can they now be deemed to be "solved"?

- in all cases it does help greatly all concerned if you mark any post that best helped as the solution in any discussion that you start.

I have moved the solution to Andy's post.
