SET SERVICE

Defines a new entry or modifies an existing entry in the services database.

The /FILE, /PORT, /PROCESS_NAME, and /USER_NAME qualifiers are required when defining a new entry and optional when modifying an existing one.

Related command: SHOW SERVICE

Format

SET [NO]SERVICE service
{ /FILE=startup_file
/PORT=n
/PROCESS_NAME=process
/USER_NAME=vms_user_account }
[ /ACCEPT=options ]
[ /ADDRESS=IP_address ]
[ /FLAGS=options ]
[ /LIMIT=n ]
[ /LOG_OPTIONS=options ]
[ /PROTOCOL=protocol=options ]
[ /REJECT=options ]
[ /RPC=values ]
[ /SEPARATOR=option ]
[ /SOCKET_OPTIONS=options ]

restrictions

You cannot modify the following fields in an existing entry:
  • service
  • /ADDRESS
  • /PORT
  • /PROCESS_NAME
  • /PROTOCOL (except for the optional settings)

To make changes to these fields, use SET NOSERVICE to delete the entry and then re-create the entry.

Note
There is no RCP service. RCP uses the RSH server process.

HP strongly suggests that, for the services provided by TCP/IP Services, you do not use this command to reset the following:

  • The required qualifiers
  • The /FLAGS qualifier, except for the APPLICATION_PROXY and CASE_INSENSITIVE options

Using SET NOSERVICE without either a specified service or specified qualifiers deletes all entries for all services.

Requires write access to the directory with the services database.

Parameters

service

Required for SET SERVICE; optional for SET NOSERVICE.

Service you want to modify or enter into the services database.

Qualifiers

/ACCEPT {=[NO]HOSTS=(hosts) | =[NO]NETWORKS=(networks)}

Optional. Default: Offers the service to all hosts on all networks.
  • /ACCEPT=HOST=(host)
    • Grants host or hosts access to the service.
    • Denies access to all other hosts.
  • /ACCEPT=NOHOST=host removes access to the service for a host that previously gained access with /ACCEPT=HOST.

The following options are available:

Option Meaning
HOSTS= hosts Makes the service available to the specified hosts.
Denies all other hosts access to the service.

Maximum is 32.

Example: 

/ACCEPT=HOSTS=(
host1_name,
host2_name,
host3_address)
NOHOSTS= hosts Removes the specified hosts from the accept list so they cannot gain access to the service. You can specify a wildcard character (*) in place of the hosts list to remove all hosts from the accept list.

Maximum is 32.

Example: 

/ACCEPT=NOHOSTS=(
host1_name,
host2_name,
host3_address)
NETWORKS= networks Makes the service available to the specified networks. Denies access to the service to all other networks.

Maximum is 16.

For each network, you can optionally specify the network mask. The default network mask equals network's class number. For example, for the network 11.200.0.0., the default mask is 255.0.0.0.

Example: 

/ACCEPT=NETWORKS=(
net1_name,
net2_address,
net3:
net3mask)
NONETWORKS[= networks] Removes the specified networks from the accept list so they cannot gain access to the service. You can specify a wildcard character (*) in place of the networks list to remove all networks from the accept list.

Maximum is 16.

For each network, you can optionally specify the network mask. The default net mask equals network's class number. For example, for network 11.200.0.0., the default mask is 255.0.0.0. 

/ACCEPT=NONETWORKS=(
net1_name,
net2_address,
net3:
net3mask)

/ADDRESS=IP_address

Optional. Default: 0.0.0.0 (all local interfaces receive incoming requests for the service).

If you have multiple Internet interfaces and, therefore, more than one IP address, /ADDRESS specifies the particular address on which incoming requests are received.

To define a service name more than once, use /ADDRESS with different values for each instance. A reason to duplicate a service name, for example, is that your local host has three interfaces and you want to make a service available on two of them. Each service/interface pair must be unique.

/FILE=startup_file

Required if defining a new service entry; optional if modifying an existing one.

Name of the service's startup command file.

/FLAGS= {[NO]APPLICATION_PROXY | [NO]MULTITHREAD | [NO]PROXY | [NO]CASE_INSENSITIVE}

Optional.

The flag options are:

  • [NO]APPLICATION_PROXY. Default: NOAPPLICATION_PROXY.
    The service does its own proxy checking. This allows connections based on defined proxies.
    Applies to: remote shell (RSH) and line printer daemon (LPD).

    Note
    The ROOT account does not require a communication proxy in the proxy database. The setting of /FLAGS=APPLICATION_PROXY flag is not relevant.
  • [NO]MULTITHREAD. Default: NOMULTITHREAD.
    While connecting a socket to a remote host and passing the socket to the requested server, the auxiliary server continues to listen for incoming requests.
  • [NO]PROXY. Default: NOPROXY.
    User account information is from the proxy database.
  • [NO]CASE_INSENSITIVE. Default: CASE_INSENSITIVE.
    Case sensitivity of the remote user name in the proxy database.
    Use with /PROXY.

/LIMIT=n

Optional.

Maximum number of copies of the requested service allowed to run on the system. If the maximum number is reached, any additional requests for the service are rejected.

/LOG_OPTIONS=
[ [NO]ACCEPT ] [ [NO]ACTIVATE ] [ [NO]ADDRESS ] [ [NO]ALL ] [ [NO]CONNECT ] [ [NO]DEACTIVATE ] [ [NO]ERROR ] [ [NO]EXIT_CLEANUP ] [ [NO]LOGIN ] [ [NO]LOGOUT ] [ [NO]MODIFY ] [ [NO]REJECT ]

Sets the specified logging options for the service you are configuring.

The logging options have the following meanings:

Option Meaning
[NO]ACCEPT Message is logged when a request is accepted.
[NO]ACTIVATE Message is logged when the service is activated.
[NO]ADDRESS For auxiliary server messages and OpenVMS security events, the message displays the IP address as a host name. If host names are not relevant, HP recommends that you specify [NO]ADDRESS.
[NO]ALL Messages are logged for all events.
[NO]CONNECT Message is logged when the auxiliary server issues a connect request back to the client. The services that usually make this request (on a second socket) are remote shell and remote execute.
[NO]DEACTIVATE Message is logged when the service is being deactivated.
[NO]ERROR Message is logged when an error is detected while processing a request to the service.
[NO]EXIT_CLEANUP Message is logged when the service fails to complete startup (that is, the server did not assign the BG device, with logical name SYS$NET, or did not issue a C socket before exiting).
[NO]LOGIN Message is logged when a connected terminal server accepts a remote login request.
[NO]LOGOUT Message is logged when a connected terminal server terminates a connection.
[NO]MODIFY Message is logged when the active service is being modified.
[NO]REJECT Message is logged when a request is rejected.

/PORT=n

Required if defining a new service entry. Cannot be modified; use SET NOSERVICE to delete the entry and then re-create the entry with the modification you want to make.

Port number that the service will use. Specify a number from 1 to 65535.

/PROCESS_NAME=process

Required if defining a new service entry. Cannot be modified (use SET NOSERVICE to delete the entry and then re-create the entry with the modification you want to make).

Name of the service's process.

Specify a character string up to 15 characters long. The name is truncated to 15 characters if it exceeds that limit.

/PROTOCOL=protocol [=options]

Optional. Default: TCP.

Protocol, and its parameters, that the service will use. To set these parameters, use the following options:

Protocol Option Meaning
IP TYPE_OF_SERVICE= n Type of service, expressed as a value between 0 and 255.
  TIME_TO_LIVE= n Maximum number of hops that packets can traverse before being dropped.
TCP
(stream
socket
type) 		[NO]DELAY Delays sending packets, allowing multiple packets to be combined into a single larger packet before transmission.
Default: DELAY.
  DROP_COUNT= n TCP connection-request timeout interval for the service.

Maximum number of seconds to probe for idle TCP connections before such a connection times out and closes.
  PROBE_TIMER= seconds Number of seconds between probes for idle connections.
UDP None Datagram socket type.

/REJECT {=[NO]HOSTS=(hosts) |=[NO]NETWORKS=(networks) |=[NO]MESSAGE="text"] }

Optional. Default: No rejections if /ACCEPT is set to its default (service all hosts).
  • /REJECT=HOST=host denies host access to the service.
  • /REJECT=NOHOST=host regrants host access to the service.

The following options are available.

Option Meaning
HOSTS= hosts Makes the service unavailable to the specified hosts.

Maximum is 32.

Examples:

/REJECT=HOSTS=( host1_name, host2_name, host3_address)

/REJECT=HOSTS=*

NOHOSTS= hosts Removes the specified hosts from the reject list. You can use the wildcard character (*) in place of the hosts list to remove all hosts from the reject list.

Maximum is 32.

Examples:

/REJECT=NOHOSTS=( host1_name, host2_name, host3_address)

/REJECT=NOHOSTS=*

NETWORKS= networks Makes the service unavailable to the hosts on the specified networks.

Maximum is 16.

For each network, you can optionally specify the network mask. The default net mask equals network's class number. For example, for network 11.200.0.0., the default mask is 255.0.0.0.

Example:

/REJECT=NETWORKS=( net1_name, net2_address, net3: net3mask)

NONETWORKS[= networks] Removes the specified networks from the reject list. You can use the wildcard character (*) in place of the networks list to remove all networks from the reject list.

Maximum is 16.

For each network, you can optionally specify the network mask. The default net mask equals network's class number. For example, for network 11.200.0.0., the default mask is 255.0.0.0.

Example:

/REJECT=NONETWORKS=( net1_name, net2_address, net3: net3mask)

[NO]MESSAGE= text
NOMESSAGE 		Message sent to "reject-list" clients when TCP/IP Services rejects their request for the service.

Optional.

Specify a character string up to 63 characters.

Enclose the string in quotation marks.

Use this option only for a service whose clients require and support reject messages.

Messages are sent with a carriage return/line feed at the end.

For RLOGIN, RSH, and REXEC, this message is preceded by a byte with a value of 1 and is terminated with a byte with a value of 0.

/REJECT=NOMESSAGE deletes the stored message text.

/RPC=(PROGRAM_NUMBER=n, VERSION_NUMBER=(LOW=n, HIGH=n))

Required for services that use the Portmapper; otherwise, not valid. Defaults:
Service Program Number Highest Version Lowest Version
MOUNT 100005 1 1
NFS server 100003 2 2
PCNFS 150001 1 2
PORTMAPPER 100000 1 1

/SEPARATOR=option=character

Optional. Default: 0 (null).

Character that separates the following fields in received packets:

  • PORT=character
  • USER_NAME=character
  • PASSWORD=character
  • COMMAND=character

/USER_NAME=vms_user_account

Required if defining a new service entry; optional if modifying an existing service.

OpenVMS account information for users working on client systems. Required for a user to access the service.

The user must also be defined in the system user authorization file (SYSUAF.DAT).

Examples

#1 

TCPIP> SET SERVICE TOE /USER_NAME=LITTLE_PIGGY -
_TCPIP> /PROCESS_NAME=TOEd /PORT=1050 /PROTOCOL=UDP -
_TCPIP> /FILE=SYS$COMMON:[SYSMGR]TOE_STARTUP.COM

Modifies the service TOE to implement UDP on port 1050. This service has the OpenVMS process context of user LITTLE_PIGGY.

After you issue a SET SERVICE TOE command, the auxiliary server executes TOE_STARTUP.COM when a request arrives for service TOE.

#2 

TCPIP> SET SERVICE LPD -
_TCPIP> /REJECT=NETWORK=(11.30.0.0:255.255.0.0,11.40.0.0)

SHOW ARP

Displays ARP information.

Related command: SET ARP

Format

SHOW ARP [host]
[/[NO]LOCAL]

Parameters

host

Optional. Default: All hosts; same as specifying /NOLOCAL.

Specifies the host about which you want information.

Qualifiers

/LOCAL

/[NO]LOCAL

Optional. Default: /NOLOCAL.

If you either omit this qualifier or specify /NOLOCAL, the software checks the hosts database. If a lookup fails, it also checks the BIND resolver.

Limits name-to-address lookups to the local hosts database.
