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

I fixed the problem of the "high server load" by installing amanda 
version 2.4.4p1 on the server and the clients.

But the backups fail.  Checking the logs in /tmp/amanda (on the 
clients), I see things like:

sendbackup: time 0.000: stream_server: waiting for connection:
      

0.0.0.0.33011
  

sendbackup: time 0.001: stream_server: waiting for connection:

sendbackup: time 0.001: stream_server: waiting for connection:
      

0.0.0.0.33013
  

sendbackup: time 0.001: waiting for connect on 33011, then 33012, then
      

33013
  

sendbackup: time 29.991: stream_accept: timeout after 30 seconds
sendbackup: time 29.991: timeout on data port 33011
sendbackup: time 59.991: stream_accept: timeout after 30 seconds

sendbackup: time 89.991: stream_accept: timeout after 30 seconds
sendbackup: time 89.991: timeout on index port 33013
sendbackup: time 89.991: pid 1873 finish time Thu Jan  8 01:05:15 2004

All hosts were configured with:

--with-tcpportrange=850,854 --with-udpportrange=850,854

So why am I getting connections on port 33011?  I have 850-854 opened on 
the firewall, but if it's trying to connect on 33xxx then of course it's 
not going to work.

   

      

Note, I'm speaking from a position of ZERO experience on this:

>From the PORT.USAGE document:

  Pick the max of (2 * inparallel) and (3 * largest maxdumps).
  Allocate at least that many ports in the unprivileged
  (1024 or larger) range.

Three questions:

Did you allocate sufficient number of ports?
 

    

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

  

Are they in the unprivileged range?
 

    

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)/


  

Is the proper syntax for the option ...=N1,N2 or ...=N1-N2?
 

    

 --with-tcpportrange=low,high  bind unreserved TCP server sockets to 
ports within this range unlimited
 --with-udpportrange=low,high  bind reserved UDP server sockets to ports 
within this range unlimited


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

Mike
