I'm running AMANDA 2.4.4p1 compiled with the following options:
amandad: CONFIGURE_COMMAND="'./configure'
'--mandir=/usr/share/man' '--prefix=/usr'
'--infodir=/usr/share/info' '--sysconfdir=/etc'
'--libdir=/usr/lib' '--libexecdir=/usr/lib/amanda'
'--localstatedir=/var/lib' '--with-index-server=localhost'
'--with-gnutar-listdir=/var/lib/amanda/gnutar-lists'
'--with-smbclient=/usr/bin/smbclient' '--with-amandahosts'
'--with-user=amanda' '--with-group=disk' '--with-gnutar=/bin/tar'
'--with-tcpportrange=50000,50029' '--with-udpportrange=850,859'
'--disable-libtool' '--disable-shared' '--disable-static'"
After much frustration and reading anything relevant I could find
short of the source code, I compiled with the --with-*portrange
options because both the backup server and client machine are
behind firewalls. I specified a range of 10 ports because I'm
using 10 dumpers (``inparallel=10'' in amanda.conf). I've
configured both firewalls to allow traffic on UDP 850 - 859 and
TCP 50000 - 50029.
When I run amdump, it completes backup of the server disks as
expected, but fails to receive backups from the client. I see in
the server's firewall logs that the client is attempting to
connect to the server on UDP ports 591 and 835. These packets
are, of course, denied, because I've only opened 850 - 859. I've
attached a copy of the only debug file that is created in
/tmp/amanda on the client.
I understand that AMANDA tries first to use the user UDP port
range and then, if that fails, tries for any privileged port.
So presumably, it was unable to use ports 850 - 859. I'm unaware
of anything else using these ports on either the client or the
server.
Strangely, I've already made a successful test run with the same
configuration (except for changing to record=yes and disabling the
use of an exclude file).
Where should I proceed from here with troubleshooting?
