Amanda Server on Cygwin amdump not working :-S
2006-08-21 04:55:32
Hi list:
I'm pretty new to amanda, but i'll try to explain myself :-)
I am trying to use amanda for backups using a Windows host for backups
(just to disk, no tape dev.)
I succesfully (aparently) compiled amanda server following the instructions
on: http://www.amanda.org/docs/howto-cygwin.html (removing the --without
server on the ./configure step, of course ;-) )
The problem is with the amdump the taper seems to bizarrely stop working.
This is the tipical e-mail report:
---------------------------------------------
*** THE DUMPS DID NOT FINISH PROPERLY!
The next tape Amanda expects to use is: a new tape.
The next new tape already labelled is: HISS01.
FAILURE AND STRANGE DUMP SUMMARY:
machine1 /tmp RESULTS MISSING
dumper: FATAL must be run setuid root to communicate correctly
driver: FATAL reading result from taper: Software caused connection abort

The Amcheck program for that configuration (see below amanda.conf) tells
this:
$ /usr/local/sbin/amcheck DailySet1

Amanda Backup Client Hosts Check
--------------------------------
Client check: 1 host checked in 0.031 seconds, 0 problems found
(brought to you by Amanda 2.5.0p2)
That is pretty weird since user running all this stuff is Administrator, but
anywway i checked out the permissions and the seem fine to me.
Planner, dumper and amcheck have -rwsr-x--- permissions and i tested it with
chowning to Administrator, SYSTEM and root (an administrator user) and that
seems to do nothing different.
This is my amanda.conf for DailySet1:
#-------------------

#-------------------
¿Some clues?
Thank you very much in advance.
