Are those files compatible between Linux and Solaris?  I suppose they
are if it's working so far.

Perhaps try repeating the command with the -vv option to get some
debugging output.

Working over SSH should be fine.  In this case you don't need a
rsyncd.conf file.

They are compatible.  The formats have been standardised
since long before even POSIX.  I've shared them via NIS.

I wonder if there might be a permissions mismatch or group
membership issue.  You could try doing them in a different
order.  I'd also consider doing a pull, fewer authentication
issues that way.

You might want to consider using NIS.  With the exception of
automount all the applicable files are compatible.
