A caution to those upgrading to Networker 6.1.3:
I just upgraded our Solaris 8 sparc Networker Server from
6.1.1 to 6.1.3 and some of our unix clients could no longer
backup to the server.

These Networker clients do not run the nsrexecd daemon
(for well founded security reasons)
and instead use rsh with a non-root "Remote user" attribute
in the client's resources.

When Networker backups are invoked from the server using rsh, the rsh of
the operating system is by-passed for an rsh that is built-in to the
savegrp command. The trouble with Networker 6.1.3 server is that the
 rsh client implementation is broken.
The secondary rsh port for stderr is not explicitly requested as a secure
port and, thus the Networker client's rsh server will drop the connection.
The Networker 6.1.1 server did not have this problem.

I will try to open up a case with Legato Tech. Support asap.
