Need help with GDB test run: Asks for password although ssh setup not to require password.

["Anmol P. Paralkar" <b07584@freescale.com>]

Hello,

  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. However, I see
  these failures in my gdb.log file:

-------------------------------------------------------------------------------- 
spawn ssh -l b07584 perf1vme6 gdbserver :4004 vmx21726.x^M
  b07584@perf1vme6's password: board_info host exists name

target remote perf1vme6:4004^M
perf1vme6:4004: Connection refused.^M
(gdb) Connection refused by remote target.  Pausing, and trying again.
--------------------------------------------------------------------------------

  The: "perf1vme6:4004: Connection refused" is due to the gdbserver not being up
  on the target and I think, that, in turn is due to the password being asked when:
  "spawn ssh -l b07584 perf1vme6 gdbserver :4004 hello" happens.

  If I run the ssh by hand, I am not asked for a password, I do see something like:

----------------------------------------
Process hello created; pid = 550
Listening on port 4004
----------------------------------------

  and I can remote connect and debug as given in the GDB User Manual.

  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.

Thanks,
Anmol.
