[comp.sys.hp] dump/rdump on HP 9000/400 HP-UX 7.02

     I've been trying to port our local dump/rdump program to our HP
9000/400 machines.  It is based mainly on BSD sources.  We need to use
the local version because it allows dumping of an active filesystem,
and especially because you can specify userid@tapehost:/dev/exabyte
instead of just tapehost:/dev/exabyte (for extra security).

     The first problem I ran into was that the machine would crash
with:

`date` Network BUFS Error 3000
Append operation on socket buffer failed for lack of reservations

panic: tcp_input: Header prediction

This seemed to happen during/after a call to setsockopt(), about which
I could find no documentation in the man pages.  After commenting this
line out, rdump runs, but slower than on other machines.

     However, upon looking at the result of the dump on the exabyte,
there are some directories that were not copied (/users, for example).
So, now I'm stuck.  I imagine that there is some difference in the way
directories are handled, but I'm not sure how to proceed.

     Has anyone already done this?
