Hi everybody!

We are using amanda software to backup our servers and workstations on
our department and we have a problem with the iptables configurations of
some of the amanda clients.

The problem is with the stations with SL 4.x and with kernel version
2.6. Using the same configuration as in SL 3.0.5 (kernel 2.4) for the
iptables software the ones with SL 4.x reports error when trying to make
the backup because the server cannot connect to TCP ports suggested by
the client. Those ports are not opened by default on the iptables
configuration, the ip_conntrack_amanda module loaded from the
/etc/sysconfig/iptables-config file, should open those ports (ramdomly
chosed by the client) related to the first connection.

So it seems that the ip_conntrack_amanda module on kernel 2.6 does not
work properly. Any ideas? Any bug? One posible solution could be to open
the range of ports from which client randomly select the port to dump
the backup to server. Does anybody knows what this range is in the
amanda-client RPM package on SL4.x?

Thanks in advance if anybody may help me. Maybe I should post the
question on any amanda mailing list.

Jorge
