It seems that all *nix versions do automount and nfs slightly different than each other.  I was setting up a automount on AIX 5.2L and discovered that I needed a nfs.direct file in /etc to mount to a directory.  Anyway, it looks like this:

/etc/nfs.direct

/oracle -rw,hard,intr tulnfs01:/data/oracle

/etc/auto_mount

/-      /etc/nfs.direct

Once those files are created, you can run /etc/rc.nfs and the nfs subsystem along with automount will start.

This is not totally unknown, but I was trying to mount a fedora core 8 NFS exported file system. but I kept getting the error:

vmount: operation not permited

Luckily I ran across this web page:

AIX versions 4.x and 5.x

Sometimes Linux NFS servers will do port checking and require that the NFS client use a reserved port.

     nfso -o nfs_use_reserved_ports=1

If the mount is going to be permanent, then the change needs to survive across a reboot. The nfs option must be changed permanently. On AIX 4.x and 5.1, the command above should be added to the startup scripts (possibly /etc/rc.nfs). On AIX 5.2 and above, the change can be made permanent by adding the -p flag.

     nfso -p -o nfs_use_reserved_ports=1
