I'm using Amanda version 2.5.1p3 for server and clients. The OS I used is
RHEL4. The problem is the result was not occur for all clients. Before this
the Amanda server can do backup and the result only showed STRANGE not
FAILED OR MISSING. This case only occured couples day ago. That why I was
wondering that the network caused this error. I didnt do any change to all
of them.
