Re: Network / Seurity with ports?

[Steve Bertrand]

Hi Neil,

I just recently posted the following after finding the answer in google 
groups after weeks of searching:

The problem:  My amanda box is behind a Netopia 7100-c nat gateway, and 
the netopia box mapped amanda ports to ports above 5, which amanda 
deems as insecure.  The netopia box does not appear to have any way to 
re-map the ports, so I was stuck.  My amanda box is co-located on a 
colleagues network, so I couldn't just put the amanda box as the gateway.

Here's what I did to fix it:

- open common-src/security.c within the amanda source tree
- comment out the if-statement block that starts with
  if(ntohs(addr-sin_port = IPPORT_RESERVED) {

For the non-developers, you can comment out the entire code block by 
putting the /* symbols before the block to start the comment, then the 
*/ symbols after the block to close the comment quote.

Merry Christmas,

Steve Bertrand

Host_A is the backup server and Host_B is the client to be backed up.
I have the following problem;

bash-2.05$ amcheck -c daily

Amanda Backup Client Hosts Check

ERROR: Host_B: [host Host_A: port 32782 not secure]
Client check: 1 host checked in 0.085 seconds, 1 problem found

Each time I run this the port number increases by one. The client is
running Mandrake8.2, the server Solaris8. I'm guessing the problem is
security, maybe on the client and the random port used talking back to
the server. Both the server and the client use the standard 10080.
Thanks in Advance for any help.

Neil..

There's a firewall sitting between the client and server doing NAT/IP
masquerading, right?  NAT/masq changes the port numbers and amanda
doesn't like that.

I can't tell you the solution, but that's most likely the problem.
