If you are using A/UX 2.0 or 3.0, bring the system to single-user mode and type the command:
newconfig nfs
Then, follow the steps below:
1) Edit /etc/exports to specify hosts eligible to mount file systems from
this server. In this file, you will specify what partitions you will
allow to be mounted and what systems may be mounted.
For example: to let anyone on the system "hostname1" mount a file
partition named "/u1", you would enter the line to /etc/exports:
/u1 hostname1
2) Check that a file system has been exported to this system; enter the
command-line: showmount -e
The output should look similar to the following:
/ hostname1
/users hostname1 hostname2
