MOUNTPW command syntax
Note: Much of the need for MOUNTPW as described below is gone if PCNFSD is available on your NFS server, since user ID and password information can be passed on PCNFSD requests. This applies to mounts for SFS directories, BFS directories, and minidisks protected by External Security Managers (ESMs). A minidisk protected by link passwords must still provide the password on the MOUNT or MOUNTPW command.
The MOUNT command can pose a security problem, because NFS client systems often store this command's argument values to respond to a later query asking for information about the mounts that are currently in effect. A password supplied in an argument to a MOUNT command could then be revealed in the query response to someone other than the user who executed the MOUNT command. The MOUNTPW command provides an alternative path for sending password, account, and user ID information to the VM NFS server. This information can then be omitted from the subsequent related MOUNT command, and therefore is not present in a display of currently mounted file systems.
A MOUNTPW command precedes the related MOUNT command, which must follow within 5 minutes. After 5 minutes, the VM NFS server discards the information it received in a MOUNTPW command. If a second MOUNTPW command is issued for the same CMS disk or directory before a MOUNT command for that object, the data from the first MOUNTPW command is discarded. See the MOUNTPW command for parameter descriptions.
