I noticed that the amanda server uses udp port 993 as the src. so the
first part of the amanda network conversation goes like this:
server port 993 -> client port 10080 hi
server port 993 <- client port 10080 hi back
server port 993 -> client port 10080 sendsize
server port 993 -> client port 10080 ack sendsize
Is this correct? does amanda always use port 993 as the source port?
It uses a random privileged (<1024) port.
I hypothesize that my dumps are only finishing sometimes because port
993 is blocked by default. port 993 works work only a few minutes until
the "allow related" rule timesout.
I understand it you have iptables/netfilter on the server? Then this
might well be the reason. However, then it should also fail during daytime.
When amanda uses tcp instead of udp for the backup, are all of the tcp
connections made from the server to the client?
How I I force amanda to use tcp instead of udp?
I have had the backup fail during the day when I run it, but it usuaully
fails at night. I think that the estimate times vary and that when the
estimate time exceeds some firewall timeout value, then it fails because
it no longer fits the iptables "related" rule. Can I use the tcp
connections to get around this?
Sincerely,
