Add lines like the following to this file:
MACHINE=hostname1:hostname2 \ REQUEST=yes \ SENDFILES=yes \ READ=/ WRITE=/ \ COMMANDS=ALL LOGNAME=nuucp \ REQUEST=yes \ SENDFILES=yes \ READ=/ WRITE=/ \ COMMANDS=ALL |
It is standard practice to use nuucp as the LOGNAME, but this is not mandatory.
You may want to set more restrictive permissions than those shown above. For more detail, refer to the SunOS 5.x Administering TCP/IP and PPP.
