file for rexecd.
7. A null byte is returned on the connection associated with
stderr and the command line is
passed to the normal login shell of the user with that shell’s
-c option. The shell inherits the
network connections established by
rexecd.
rexecd uses the following path when executing the specified command:
/usr/bin:/usr/ccs/bin:/usr/bin/X11:/usr/contrib/bin:/usr/local/bin
Transport-level keepalive messages are enabled unless the
-n option is present. The use of keepalive
messages allows sessions to be timed out if the client crashes or becomes unreachable.

DIAGNOSTICS
