 I am trying to setup GDB DejaGNU remote testing using gdbserver. I have set things up so
 that I can ssh to my target machine without it asking for my password.

Which method did you use for that?

I had used: http://www.debian.org/devel/passwordlessssh


but please read on, below.


 Is the failure I am seeing in the DejaGNU run really due to the gdbserver not being
 up prior to the remote connect attempt on the hostside GDB in turn, due to the password
 being asked on the ssh? What am I doing wrong here? Kindly help.

Most likely some environment variables are lost, maybe SSH_AUTH_SOCK.

I was using instructions from:


http://www.stlinux.com/docs/manual/development/advanced_development12.php

In particular, I needed to make this change:

 I hand-patched (lesson learnt!), and ended up overlooking the space (between the -l and $username)
 as I made the change, and got the "Connection refused"'s. I do not see the problem after having
 taken care of that.

Thank you very much for your response.
