Mike:
There may be a bit of misunderstanding here. The TCP ports may be in the
unprivileged range, since the ones we use here are 50000-50040. We do have
the UDP ports in the range of 890-899. See if you can try a different range
on TCP ports and, if possible, allocate a larger range of ports (since
Amanda will reuse them, but cannot use more than the port range at one
time).
Our options to the configure are:
--with-portrange=50000,50040 --with-udpportrange=890,899
Best of luck,
Don

Looking at that, I don't think so. I have inparallel=4, and I have no
maxdumps set so the default is 1. I can reduce the inparallel number to
see if that makes a difference. Currently I have ports 850-854, which
is only 5

No, they are not, but that seems to contradict the Amanda FAQ which is
what I followed.
http://amanda.sourceforge.net/fom-serve/cache/139.html
/You must pick ports under 1024 or amanda will complain of "insecure
ports used" those ports should of course not conflict with other
services listed in /etc/services. ( I suggest 850-854 or 859)/

So the command I used --with-tcpportrange=850,854 should be correct.
