RE: Troubleshooting new Amanda client: Amanda user?
2007-06-22 15:29:22
Kevin, thanks so much for writing. I appreciate your suggestions and
questions.
Here's /etc/xinet.d/amanda:
[root@tobaccodev ~]# cat /etc/xinetd.d/amanda
# default: off
# description: The client for the Amanda backup system.\
# This must be on for systems being backed up\
# by Amanda.
service amanda
{
socket_type = dgram
protocol = udp
wait = yes
user = amanda
group = disk
server = /usr/lib/amanda/amandad
disable = no
}
[root@tobaccodev ~]#
No 'auth' seems to be indicated.
The disklist entry for the 'tobaccodev' host on the tapehost is:
backup@cn2:~$ grep tobaccodev /etc/amanda/DBackup/disklist
# tobaccodev host
# Uncomment when internal DNS set up for tobaccodev
tobaccodev /dev/mapper/VolGroup00-LogVol00 tar #tobaccodev: /
tobaccodev /dev/sda1 tar #tobaccodev:
/boot
backup@cn2:~$
No 'auth' is indicated there, either. The 'tar' dumptype is defined on
the tapehost with:
define dumptype global {
comment "Global definitions"
index yes
}
define dumptype tar {
global
program "GNUTAR"
}
Also, something may have just changed because of changes in my
tobaccodev:~amanda/.amandahosts file, based on suggestions from Gene
Heskett. This file now reads:
[root@tobaccodev ~]# cat ~amanda/.amandahosts
centernet.jhuccp.org backup amdump amindexd amidxtaped
cn2.jhuccp.org backup amdump amindexd amidxtaped
[root@tobaccodev ~]#
This seems to now have caused the amanda log files to be written:
[root@tobaccodev ~]# ls -la /var/log/amanda/amandad.200706221*

I'm still getting an error, and this log file doesn't clearly indicate
to me the source of the problem.
Thanks, again, for your help.

what dumptype(particular what auth) is used?
Please list /etc/xinet.d/amanda file.
Additional auth (bsdtcp, bsdudp) are added to Amanda 2.5.1.
Please see
