Unlike the other databases, which have similar objects, the configuration database holds diverse initialization information for various TCP/IP Services components.
The following commands modify the configuration database:
The CREATE commands create the following kinds of files:
To add and delete records from the TCP/IP Services databases, use the CONVERT, ADD, and REMOVE management commands.
Use the following commands to add records to and delete records from the proxy and export databases:
You cannot modify information that you enter into databases. Instead, delete the record with the REMOVE command and then issue a new ADD command.
TCP/IP Services provides the following kinds of CONVERT management commands:
You can start and stop software components interactively by using the following commands:
For example:
TCPIP> START ROUTING /SUPPLY |
For the server components that are started by the auxiliary server upon an incoming client request, the ENABLE SERVICE command tells the the auxiliary server to listen for requests and act upon them.
The DISABLE SERVICE command tells the auxiliary server to stop listening for incoming requests.
Use the following commands to set components to start when TCP/IP Services starts. The permanent configuration is stored in the configuration database.
Use the following commands to verify the integrity of TCP/IP Services files:
The NFS server requires the following management commands:
The TCP/IP Services software includes commands for using NFS. Use the following commands to view container file systems and to copy files to and from them:
For using the NFS client (working with files that reside on remote hosts), TCP/IP Services software provides the following commands:
The SHOW and LIST commands display configuration, status, and
performance information.
1.2 UNIX Management Commands
You can use UNIX management commands to manage the TCP/IP Services
software. Section 1.2.1 lists the supported UNIX management commands,
and Section 1.2.2 gives a few tips about using UNIX management commands
and provides sources for more information.
1.2.1 Supported UNIX Management Commands
Table 1-3 describes the supported UNIX commands.
Command | Description |
---|---|
arp | Controls and displays ARP tables for the specified host. |
ifconfig | Configures or displays network interface parameters, redefines an address for a particular interface, or sets options such as an alias list, broadcast address, or access filter. |
netstat | Displays network statistics of sockets, data link counters, specified protocols or aliases, network interfaces, and a host's routing table. |
nfsstat | Displays statistical information about the network file system (NFS) and remote procedure call (RPC) interfaces in the kernel. It can also be used to reinitialize this information. |
ripquery | Requests all routes known by a RIP gateway by sending a RIP request or a POLL command. |
route | Allows you to manipulate the routing table manually. Normally, a system routing table management component, such as GATED or ROUTED, will tend to this task. |
sysconfig | Manages and displays network attributes in the kernel subsystem configuration. |
sysconfigdb | Manages and displays network attributes in the subsystem configuration table (TCPIP$ETC:SYSCONFIGTAB.DAT). |
traceroute | Displays the route that packets take to a network host. |
whois | Displays user, host, and organization names in the Network Information Center (NIC) database. |
To use UNIX management commands at the DCL prompt, execute the command procedure SYS$MANAGER:TCPIP$DEFINE_COMMANDS.COM. For example:
$ @SYS$MANAGER:TCPIP$DEFINE_COMMANDS.COM |
This command procedure defines process-specific commands that enable you to enter UNIX commands from the DCL prompt. Note that execution of a UNIX command in a DCL command procedure does not return an error in $STATUS, so you cannot test for the failure of a UNIX comand in a DCL command procedure.
The following command shows how to obtain information about an interface configured on your host. Note the use of quotation marks to preserve the case of the command option. You must enclose uppercase options in quotation marks when entering UNIX commands.
$ ifconfig "WF0" |
The following is displayed:
WF0: flags=c43<UP,BROADCAST,RUNNING,MULTICAST,SIMPLEX> rxmt 1000, reach time 30000, dad tries 1, MT 4352, hops 64, token len 64 inet 16.20.208.100 netmask ffff0000 broadcast 16.20.255.255 ipmtu 4470 inet6 fe80::200:f8ff:fe66:2e35 |
For more information about UNIX command options and flags, refer to the HP TCP/IP Services for OpenVMS Tuning and Troubleshooting manual, or enter HELP unix_command at the TCPIP> prompt. For example, to display information about the netstat command, enter:
TCPIP> HELP NETSTAT |
This chapter describes the TCP/IP Services management commands in alphabetical order.
For information about how to enter commands, see Chapter 1.
Adds an export entry, in the form of a UNIX path name, to the export database for a Network File System (NFS) file system. The path name is a name that is mapped to one of the following:
- An OpenVMS disk
- A subdirectory on an OpenVMS disk
- A UNIX container file system
Related commands: MAP, REMOVE EXPORT, SET CONFIGURATION MAP, SHOW EXPORT, SHOW HOST
Applies to: NFS server
ADD EXPORT "/path/name"
/HOST=host
[ /OPTIONS=
[NO]DATA_CONVERSION
[NO]NAME_CONVERSION
[NO]PURGE_VERSIONS
[NO]TYPELESS_DIRECTORIES ]
This command requires read and write access to the export database. The following restrictions and instructions apply:
- Do not use wildcards within a UNIX directory specification.
- For each host, define both its host name and any alias names.
- For each entry, use uppercase and lowercase consistently.
- If you remove an export entry and replace the entry using different options; each client must dismount and remount for the new options to take effect.
"/path/name"
Required.File system to add to the export database.
Separate directory and subdirectory names with slashes.
/HOST=host
Required.The NFS client host or hosts that will have access to the specified NFS file system.
You can use a wildcard to allow access to all hosts.
/OPTIONS= { [NO]DATA_CONVERSION |[NO]NAME_CONVERSION |[NO]PURGE_VERSIONS |[NO]TYPELESS_DIRECTORIES }
Optional.
Note
For clients operating in OpenVMS to OpenVMS mode, the server ignores the options in the export record and uses the settings required for OpenVMS to OpenVMS mode.Options for the specified directory:
- DATA_CONVERSION, NODATA_CONVERSION
- DATA_CONVERSION (default)
Converts the following kinds of sequential files:
- Variable
- Variable with fixed-length control (VFC)
- Fixed-record formats
Converts sequential files according to the rules applied by the following record attributes:
- Carriage return/carriage control (CR)
- Fortran carriage control (FTN)
- Print file-format control (PRN)
Stream formats are returned unconverted.
The data in files with nonstream records cannot be written back to the file.- NODATA_CONVERSION
File data is considered raw and is returned without conversion. Nonstream records are returned with their record control information mixed with the record data. Files can be rewritten randomly.- NAME_CONVERSION, NONAME_CONVERSION
- NAME_CONVERSION
A non-OpenVMS client can create files with mixed-case names and names containing characters that are invalid for OpenVMS file names. The server converts such names to valid OpenVMS file names, and reverses the conversion when displaying the file names to a non-OpenVMS client.- NONAME_CONVERSION (default)
Clients can only create files with valid OpenVMS names. The server performs case-insensitive lookups and displays directories in lowercase.- PURGE_VERSIONS, NOPURGE_VERSIONS
Default: NOPURGE_VERSIONS
Deletes multiple versions of files. (The NFS CREATE and RENAME calls can create multiple versions. The NFS READDIR call can sense multiple versions.)- TYPELESS_DIRECTORIES, NOTYPELESS_DIRECTORIES
- TYPELESS_DIRECTORIES
Removes .dir.1 from the name of directories. A naming conflict could arise if, for example, two files exist in the parent directory:
DOVE.;1 (regular file)
DOVE.DIR;1 (directory file)
The name is returned as dove. , rather than dove , if a file and a conflicting directory exist.- NOTYPELESS_DIRECTORIES (default)
Returns names as file.ext and file.dir .

TCPIP> ADD EXPORT "/gold/finch" /HOST=GOLD |
Adds the name of UNIX directory /gold/finch to the export database and gives NFS client users on the remote host gold access to this directory.
#2 |
---|
TCPIP> ADD EXPORT "/gold/finch" /HOST=(PURPLE,FINCH) |
Adds the directory /gold/finch to the export database and gives NFS client users on multiple remote hosts (PURPLE and FINCH) access to this directory.
Adds entries to the proxy database that give remote users an OpenVMS identity (account name). Applies to the NFS server, NFS client, PC-NFS, RSH, LPR/LPD, and customer-developed services.The proxy database contains communication proxies and NFS proxies:
- Communication proxy
- Provides an identity for users of RSH, RLOGIN, REXEC, RMT/RCD, LPR/LPD, and customer-written services, if these services are marked with SET SERVICE /FLAGS=APPLICATION_PROXY.
Note
The ROOT account does not require a communication proxy in the proxy database. The /FLAGS=APPLICATION_PROXY flag, therefore, is not relevant when you are setting up a communication proxy for a UNIX root account.- Required qualifiers: /HOST, /REMOTE_USER.
- NFS proxy
- Provides an identity for users of NFS client, NFS server, PC-NFS. No two proxies can have the same UID and host combination.
- Required qualifiers: /HOST, /GID, /UID.
You can combine NFS and communication proxies in one record.
Related commands: SHOW HOST, DCL command AUTHORIZE, CONVERT/VMS PROXY, REMOVE PROXY, SHOW PROXY
ADD PROXY user { /HOST=host | /REMOTE_USER=user }
[ /PERMANENT ]
ADD PROXY user { /GID=n | /HOST=host | /UID=n }
[ /NFS=options ]
[ /PERMANENT ]
Requires read and write access to the proxy database and one of the following privileges:
- SYSPRV
- SYSLCK
- OPER
For each host, define both its host name and alias names.
For each entry, use uppercase and lowercase consistently.
user
Required.Local OpenVMS identity for the user of: NFS server, NFS client, PC-NFS, remote shell, or LPR/LPD.
/GID=n
Required for an NFS proxy.Group identifier (GID) for an NFS user.
Wildcards not allowed.
/HOST=host
Required.Host name on which the NFS user is working.
- The host must be seen on the SHOW HOST/LOCAL display. It is important to use the SHOW HOST command to verify that the host is known to TCP/IP Services because ADD PROXY does not do this check.
- A wildcard is allowed.
- HP recommends that you define both the host name and any alias names.
/NFS=[ INCOMING | OUTGOING ]
Optional. Default: /NFS=(INCOMING,OUTGOING).Creates an NFS proxy for local clients, remote clients, or PC-NFS clients. Specify one of the following:
- /NFS=OUTGOING --- Proxy to use NFS client
- /NFS=INCOMING --- Proxy to use NFS server
- /NFS=(OUTGOING,INCOMING) --- Proxy to use both NFS server and NFS client
/PERMANENT
Optional. Default: Both permanent and volatile databases.Adds the entry only to the permanent proxy database.
- Communication proxy
- If REMOTE_USER is not active, changes are made to the permanent database.
- If REMOTE_user is active, changes to the permanent database take effect after you restart RSH, RLOGIN, or LPD.
/REMOTE_USER=user
Required for a communication proxy. Not valid on NFS proxy.Specifies the remote client's user name.
A wildcard is allowed.
/UID=n
Required for an NFS proxy.Specifies the user identifier (UID) for an NFS user.
Wildcards are not allowed.

TCPIP> ADD PROXY COUSINS /GID=10 /UID=40 /NFS=OUTGOING - _TCPIP> /HOST=("grackle","blackbird") |
Enters an NFS proxy called COUSINS for a local NFS client user named COUSINS. This user can access remote files from NFS servers grackle and blackbird .
#3 |
---|
TCPIP> ADD PROXY REMOTE_UGLY_DUCKLING - _TCPIP> /REMOTE_USER="cygnet" /HOST="babyswan" |
Adds to the proxy database communication proxy REMOTE_UGLY_DUCKLING for remote user cygnet at host babyswan .
Verifies the integrity of a UNIX container file, including the following checks:
- Superblock validation
- Inode validation
- Directory validation
- Internal allocation validation
- Directory hierarchy validation
Reports, and optionally corrects, problems within the structure of the container directory. Applies to the NFS server.
Related commands: DIRECTORY, MAP, UNMAP
ANALYZE CONTAINER device:path.name
[ /[NO]CONFIRM ]
[ /[NO]REPAIR ]
- Before you enter the ANALYZE CONTAINER command, you must map the OpenVMS volume on which the container directory resides, using the MAP command.
- Before you enter the ANALYZE CONTAINER command, unmap the container file system to prevent users from attempting to access to it while you analyze it.
- This command requires the BYPASS privilege.
device:path.name
Required.Device and container directory to analyze.
/CONFIRM
/NOCONFIRM
Optional. Default: /NOCONFIRM.Use only with the /REPAIR qualifier.
When the software encounters a problem with the services database, it displays a description and solution and then requests confirmation before making each correction. For example:
%TCPIP-E-ANA_SUP_BADIICGSIZE, Problem: Bad initial inode cell group size:bad_value Solution: Will be replaced by default size: good_value CONFIRM [Y/N/G]:Respond to the CONFIRM: prompt by entering one of the following:
- Y to repair the problem
- N to ignore the problem
- G to change to NO CONFIRMATION mode
/REPAIR
/NOREPAIR
Optional. Default: /NOREPAIR.Any errors will be repaired.
