ssh/scp discrepencies while running a testsuite

[Benjamin Collar]

Hi everyone

I'm trying to get the gdb testsuite running for a remote target. So far 
I can get simple remote tests to work, like the simple.exp from 
http://www.kegel.com/crosstool/current/doc/dejagnu-remote-howto.html

However, it's when I move to the gdb-server mode that I have great 
difficulties. So far, though, it comes down to this:

shell > ssh -l root pentium4-linux /usr/bin/gdbserver :7000 
/tmp/i386-prologue.660

----> This works *without* asking for a password <-----

shell > runtest -v -v -v -v ./gdb.arch/i386-prologue.exp
.... (lots of output... )
call_remote  download pentium4-linux 
/p01/tmp/debuggers/testsuite/./gdb.arch/i386-prologue /tmp/i386-prologue.660

Copied /p01/tmp/debuggers/testsuite/./gdb.arch/i386-prologue to 
pentium4-linux:/tmp/i386-prologue.660

call_remote  spawn pentium4-linux {/usr/bin/gdbserver :7000 
/tmp/i386-prologue.660}

spawn /usr/bin/ssh -l root pentium4-linux /usr/bin/gdbserver :7000 
/tmp/i386-prologue.660

-----> This asks me for a password <------

So what's so funky?
- scp under spawn in expect does not ask for a passwold
- ssh from the command line does not ask for a password
- ssh under spawn in expect *does* ask for a password

And thus my tests don't work. (actually, what happens is, even if I type 
in the password, it does not start gdbserver. But afaiu, it should not 
ask me).

The target board definition stuff is below. I'd appreciate it if anyone 
could help me understand the discrepency. Thanks for your time!
