Using automounting, this command mounts the /usr file system from sigma onto the OpenVMS mount point when it references the path name. The client keeps the path mounted for an inactive period of 10 minutes, after which it dismounts the path name.

#3
TCPIP> MOUNT DNFS4: /HOST="sigma" /PATH="/usr" - _TCPIP> /BACKGROUND=(DEL:00:01:00,RET:20) /RETRIES=4

Attempts to mount the /usr file system. If it cannot, it waits 1 minute and retries the connection up to 20 times.

TCPIP> MOUNT DNFS5:[USERS.MNT] /HOST="sigma" /PATH="/usr"
%DNFSMOUNT-S-MOUNTED, /usr mounted on _DNFS5:[USERS.MNT]  
  
TCPIP> MOUNT DNFS5:[USERS.MNT] /HOST="sigma" /PATH="/usr/users" /FORCE
%DNFSMOUNT-S-REMOUNTED, _DNFS5:[USERS.MNT] remounted as /usr/users on SIGMA
      

Specifies a lower level in the NFS server path with the second mount. This constitutes another path name and qualifies for an overmount.

TCPIP> MOUNT DNFS22:[USERS.SMITH.MNT] /HOST="sigma" /PATH="/usr" 
%DNFSMOUNT-S-MOUNTED, /usr mounted on _DNFS22:[USERS.SMITH.MNT]  
 
TCPIP> MOUNT DNFS22:[USERS.SMITH] /HOST="sigma" /PATH="/usr" /FORCE
%DNFSMOUNT-S-MOUNTED, /usr mounted on _DFS22:[USERS.SMITH]  
%TCPIP-I-OCCLUDED, previous contents of _DNFS22:[USERS.SMITH] occluded  
 
      

The /FORCE qualifier performs an occluded mount. If you issue the DIRECTORY command, the NFS client occludes (hides from view) the subdirectory dropped from the first MOUNT command.

To make the directory visible again, either issue the SHOW MOUNT command (both mounts will be visible) or dismount DNFS22:[USERS.SMITH].

Sends ICMP ECHO packets to hosts to determine whether they are active. Same as the LOOP command.

Format

PING [ host ]
[ /ADDRESS=xx.xx.xx.xx ]
[ /ALL ]
[ /FULL ]
[ /NUMBER_PACKETS=n ]
[ /PACKET_SIZE=n ]
[ /PATTERN="hexadecimal-string" ]
[ /[NO]ROUTE ]
[ /WAIT=n ]

Parameters

host

Specifies the host to which the test packets are sent.
Omitting host tests the TCP/IP Services software on the local node, as defined by the system logical TCPIP$INET_HOST.

Qualifiers

/ADDRESS=xx.xx.xx.xx

Optional.

Specifies the IP address of the host to which the test packets are sent.

/ALL

Optional. Default: Not all requests.

Displays all ICMP ECHO_REQUESTs, even if not in direct response to this operation.

/FULL

Optional.

Numeric output only. No attempt is made to look up symbolic names for host addresses. This occurs only when displaying ICMP packets other than ECHO_RESPONSE.

/NUMBER_PACKETS=n

Optional. Default: 4 packets

Specifies the number of packets to send. If you specify 0, packets are sent continuously until you terminate it with Ctrl/C.

/PACKET_SIZE=n

Optional. Default: 64 bytes.

Specifies the size of the ICMP ECHO_REQUEST.

/PATTERN="hexadecimal-string"

Optional.

Fills out the packet you send with up to 16 bytes, which is useful for diagnosing data-dependent problems. The string is a hexadecimal string of up to 32 characters (16 bytes).

For example, /PATTERN="ff" causes the sent packet to be filled with ones (1).

/ROUTE

/NOROUTE

Optional. Default: /ROUTE.

/ROUTE	Request is routed through the normal routing tables.
/NOROUTE	Normal routing tables are bypassed. If the host is not on the LAN, you get an error.

/WAIT=n

Optional.

Specifies the number of seconds to wait between sending packets.

Examples

TCPIP> PING dented
      

Specifies that the local host test the connectivity path to host dented .

Creates client entries in the BOOTP database.

SET NOBOOTP does not require any qualifiers.

Related commands: CONVERT/VMS BOOTP, SHOW BOOTP

SET [NO]BOOTP host
[ /FILE=file]
/HARDWARE=ADDRESS=hex_address
[ /GATEWAYS=hosts ]

host

Required.

Specifies the client to which your system will download files upon request. Enter a host name or IP address.

Qualifiers

/FILE=file

Optional.

Specifies the name of the client's system image or other file to download upon request.

• By default, upon receiving a request, BOOTP looks for this file in TCPIP$TFTP_ROOT:[host], where host is the client's host name, excluding the domain.
• If this directory does not exist, BOOTP uses:

  TCPIP$TFTP_ROOT:[000000].

• When the TCP/IP Services software receives a boot request, BOOTP verifies the existence and size of this file.

/GATEWAYS=hosts

/NOGATEWAYS=hosts

Optional. Default: None.

/HARDWARE=ADDRESS=hex_addr

Required.

Specifies the client's hardware address. For hex_addr, specify: hh-hh-hh-hh-hh-hh.

/NETWORK_MASK=IP_address

Required if you use subnets; otherwise optional.

Specifies the part of the host field of an IP address identified as the subnet.

The software calculates the default by setting the following:

• The bits representing the network field to 1
• The bits representing the host field to 0

You can divide the host field into a site-specific subnetwork and a host field. If you use subnets, you must specify a subnet field.

/SERVERS=type=host

Optional.

Specifies other servers whose names BOOTP can supply to clients. Here, host specifies a host name or IP address and type can be one or more of the following:

[NO]COOKIE	Cookie server
[NO]IEN_NAME	IEN-116 name server

[NO]RESOURCE	Resource Location Protocol (RLP) server (RFC-887)
[NO]TIME	Internet time server (RFC-868)

/TIME_OFFSET=seconds

Optional. Default: 0 seconds.

Specifies the time difference, in seconds, between the client's time zone and Universal Coordinated Time (UTC) expressed in seconds. This value is zero (0) in the British Isles and parts of Europe, a positive number for locations east of the zero meridian, and a negative number for locations west of the zero meridian.

_TCPIP> /FILE=PLOVER.SYS  
      

Adds client host PLOVER, with hardware address 08-00-2D-20-23-21 to the BOOTP database. BOOTP can respond to a remote boot request from client PLOVER with a reply packet containing the name of the file to down load and its IP address.
