Firewall, amanda client and ports
2007-07-18 08:49:19
Greetings,
my server (fiume) and my client (stremen) both have a firewall and the
client fails to be backed up (the server goes fine). amcheck reports
no problem. On the client, I have opened TCP/UDP port 10080, and TCP
ports 10082 and 10083, because I seem to have seen something like that
when googling.
I have also seen that apparently the data connection between server and
client at the time of the actual backup uses a variety of ports, or are
looking for free ports, but I do not understand really all this. Below
are the relevant error messages:
Hostname: fiume
Org : daily_backup
Config : daily
Date : July 18, 2007
These dumps were to tape daily-09.
The next tape Amanda expects to use is: daily-10.

(brought to you by Amanda version 2.5.2p1)
It looks as if everytime another port is used, but is this TCP or UDP?
Can somebody tell me what I have to tell the firewall (on opensuse 10.2), so
that it all works?
