Question for Andreas (and some info) about remote debugging ?

[David McCarthy]

First of all, DDD rocks !!!!

I have been trying to figure out how to debug a program on a remote machine. 
 In this case, the remote machine is not directly accessible by remote 
shell so the --rhost MACHINE does not work directly,  there is a number of 
commands that need to exec'd ( like telnet from A to B, then telnet B to C, 
then some additional commands ) before I get to the machine that I want to 
debug on.

SOLUTION: What I have found so far is that if do a --rhost for a local 
machine, and once gdb is started, I do a sh ( start a shell within gdb ), 
and then do the commands like telnets, etc.  and once I get to the machine I 
want to debug, I start gdb there, and attach to process.  This process seems 
to work ok on initial trial.

QUESTION: Are there any possibilites/concerns with doing what I did above 
i.e. something like ddd expecting the original gdb to respond for something, 
( bcos original gdb is now hung because I started a shell in it ).  Or is it 
safe ?

Any info is appreciated...  Thanks for your help.
