Problem with automatic database startup (dbora)

Question

I'm running Linux RHEL5 with 10g v2 database. For some reason the script fails to start the database. But when I logon as user Oracle, I can run dbstart ORCL and the database starts up fine. Below is what I see when the script runs. Not sure why the connection is refused. Thanks in advance for your help.
Starting dbora: + ORACLE_HOME=/u01/app/oracle/product/10.2.0/db_1
+ ORACLE=oracle
+ PATH=/sbin:/usr/sbin:/bin:/usr/bin:/u01/app/oracle/product/10.2.0/db_1/bin
++ hostname
+ HOST=Linux10gVM.norris.intra
++ uname
+ PLATFORM=Linux
+ export ORACLE_HOME PATH
+ rsh Linux10gVM.norris.intra -l oracle /etc/rc5.d/S99dbora start ORCL
Linux10gVM.norris.intra: Connection refused
+ pause ‘Press any key to continue...’
+ read ‘~p’ ‘Press any key to continue...’

AHA...just as I expected!!!
My automatic 11g1 start up and shutdown quit working in 3/2009
after working for months!
I suspected pam.d
Here it is : http://blog.fourthirty.org/?cat=45
#%PAM-1.0
# For root login to succeed here with pam_securetty, "rsh" must be
# listed in /etc/securetty.
auth required pam_nologin.so
auth required pam_securetty.so

# auth sufficient pam_rhosts.so
auth sufficient pam_rhosts_auth.so
