NFS Client
21.2 NFS Client Startup and Shutdown
• SYS$STARTUP:TCPIP$NFS_CLIENT_SYSHUTDOWN.COM can be used
as a repository for site-specific definitions and parameters to be invoked
immediately before the NFS client is shut down.
21.3 Registering Users in the Proxy Database
Users on your client host must have corresponding accounts on the NFS server
host. After making sure client users have appropriate accounts, you must register
them with the proxy database. The NFS client, the NFS server, and the PC-NFS
daemon all use the proxy database.
If you use TCPIP$CONFIG to configure NFS, the index file TCPIP$PROXY.DAT
is created for you. This file is empty until you populate it with proxy entries. If
you do not use the configuration procedure, use the CREATE PROXY command
to create the empty database file. The file TCPIP$PROXY.DAT resides in the
SYS$COMMON:[SYSEXE] directory by default. You can change the location of
the proxy database by redefining the logical name TCPIP$PROXY. (You can also
create a proxy database file from a UNIX formatted
/etc/password file by using
the CONVERT/VMS PROXY command.)
Use the following TCP/IP management commands to manage the proxy database:
• ADD PROXY
• REMOVE PROXY
• SHOW PROXY
For example:
TCPIP> ADD PROXY username /NFS=type /UID=n /GID=n /HOST=host_name
Changes in the proxy database take effect only after you dismount all DNFSn:
devices and remount them. An exception is DNFS0:, which is present if the NFS
client driver is loaded and cannot be mounted or dismounted.
Each entry in the proxy database has the fields that are listed in Table 21–1.
Table 21–1 Required Fields for NFS Proxy Entries
Field Meaning
OpenVMS user name Name of the NFS user’s OpenVMS account
Type Direction of NFS communication allowable to the user. Specify
one of the following:
• O (outgoing). Used by the NFS client.
• N (incoming). Used by the NFS server.
• ON (outgoing and incoming). Used by both client and
server.
• D (dynamic). Entry is loaded in the server’s dynamic
memory. When the NFS server starts, it creates a copy of
the proxy database in dynamic memory. (If the account
does not exist or the account is disabled, the entry for the
account will be missing from dynamic memory.)
