| + | * **Mount error** | ||
| + | <code> | ||
| + | NFS lookup failed for server : rpc error 7 (RPC: 1832-010 Authentication error) errno 5 | ||
| + | </code> | ||
| + | |||
| + | Try: | ||
| + | <cli prompt='#'> | ||
| + | # nfso -p -o portcheck=1 | ||

| + | </cli> | ||
| + | |||
| + | * **Set range ports for NFS** | ||
| + | |||
| + | Normally, The usage of NFS ports will be dynamically in AIX.... If you would like to set the port ranges, | ||
| + | |||
| + | The NFS_PORT_RANGE environment variable can be used to limit the source port of network calls the client makes to the server. If used, this environment variable should be added to the **/etc/environment** file. The format of the environment variable is as follows: | ||
| + | NFS_PORT_RANGE=udp[4000-5000]:tcp[7000-8000] | ||
