In log file of amdump I see:

 dumper: FATAL must be run setuid root to communicate correctly

Which permission  should be installed?
In server side permissions is:
-rwxr-xr--    1 root disk    30628 Dec 29 21:00 dumper
-rwxr-xr--    1 root disk     5660 Dec 29 21:00 killpgrp
-rwxr-xr-x    1 root root     4810 Dec 29 20:59 patch-system
-rwxr-xr--    1 root disk    35608 Dec 29 21:00 planner
-rwxr-xr--    1 root disk     4764 Dec 29 21:00 rundump
-rwxr-xr--    1 root disk     5048 Dec 29 21:00 runtar
-rwxr-xr-x    1 root root    18140 Dec 29 21:00 selfcheck
-rwxr-xr-x    1 root root    31912 Dec 29 21:00 sendbackup
-rwxr-xr-x    1 root root    29624 Dec 29 21:00 sendsize
-rwxr-xr-x    1 root root    33004 Dec 29 21:00 taper

In clien side permissions is:
-rwsr-x---    1 root   disk 146848 Mar 22  2005 dumper
-rwsr-x---    1 root   disk  19980 Mar 22  2005 killpgrp
-rwxr-xr-x    1 amanda disk   4810 Mar 22  2005 patch-system
-rwsr-x---    1 root   disk 148308 Mar 22  2005 planner
-rwsr-x---    1 root   disk  19036 Mar 22  2005 rundump
-rwsr-x---    1 root   disk  19184 Mar 22  2005 runtar
-rwxr-xr-x    1 root   root  78416 Mar 22  2005 selfcheck
-rwxr-xr-x    1 amanda disk  97692 Mar 22  2005 sendbackup
-rwxr-xr-x    1 amanda disk  90972 Mar 22  2005 sendsize

PS. When I changed dumper permission to -rwsr-x--- its not help.


Thanks,
