Yes, we run this configuration (Solaris<->Linux<->Solarisx86) all the time.

The failure of the 'r' commands (rsh, rcp, etc.) could be due several
different things:

o configuration in /etc/hosts.allow
o configuration in /etc/inetd.conf

It is most likely not related to /etc/pamd.conf or any of the other files.

Of course, our answer is assuming that you are having problems doing
'r' commands from Solaris to Linux.
