Mike:

Did you install the modified Amanda software on both client and server?

They have to match so that their port expectations and limitations are
consistent.

We use this configuration here with great success, but you have to install
the portlist modifications on both ends of the connection.

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:

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

        

33012, then

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.

On the server, my /etc/services has:

amanda          850/udp                         # amanda 
     

        

backup services
   

      

amanda          850/tcp
kamanda         851/tcp                         # amanda backup 
services (Kerberos)
kamanda         851/udp                         # amanda backup 
services (Kerberos)
amandaidx       852/tcp                         # amanda 
     

        

backup services
   

      

amidxtape       853/tcp                         # amanda 
     

        

backup services
   

      

The clients have:

amanda 850/udp
amanda 850/tcp
kamanda 851/udp
amandaidx 852/tcp
     

        

All I can tell you is that for me to be able to back up my firewall, I
had to create a rule that allowed my amanda server full access to all of
my high ports (>1023). I had this problem and this is what Joshua from
this listserv came back with. Worked like a charm. I would suggest
trying this.


 

    

I suppose that could be the next option, but it still does not explain 
why amanda is connecting on port 33xxx when I compiled with restrictions 
to ports 850-854.  I'm hoping someone can explain some of this to me.

Mike
