internode communication

Hi.

I use basic two-node configuration under SuSE 7.3 on intel
with failsafe 1.0.4.
In my OS configuration I deactivated ssh root connections
at all.

Now, when I try to go out from maintenance mode I got:
"node unknown error" 
and when I try to check cluster communication 
I got:
______________________
cmgr> test connectivity in cluster linux
/tmp/s1: Input/output error
Failure: Connection to samba1l.servers.citiworks.de from samba1l failed
Suggestion: (1) Ensure node 'samba1l.servers.citiworks.de' has superuser
access from samba1l
Suggestion: (2) Ensure address 'samba1l.servers.citiworks.de' is valid.
Status: Testing network connectivity...
/tmp/s1: Input/output error
Failure: Connection to mansamba1l from samba1l failed
Suggestion: (1) Ensure node 'mansamba1l' has superuser access from
samba1l
Suggestion: (2) Ensure address 'mansamba1l' is valid.
Failure: Failed to rsh to host mansamba1l

Notice: overall exit status:failed, tests failed:1, total tests
executed:1

Cluster diagnostics failed

test command failed

What's this ?
I could not find a word about network requirements of failsafe
(ssh, rsh connections ? ) and I'm a little bit confused. 

1. Why try the node to connect with itself ?
2. How can I replace rsh with ssh ?
3. Is it possible to replace root ssh connections with user 
ssh connections ?

Regards,
mpr.
