-
- Object:
-
- - PING is an MHS gateway that sends dummy messages (pings) to
- a list of target hosts and waits for an echo.
-
- - PING holds statistical data for each target host: average
- delay between sending the ping and receiving the echo, and number
- of hops between the pinging host and the target host.
-
- - PING warns the MHS administrator if no echo is received from a
- target host after four times the average echo delay for this host.
-
- PING was developped to enhance MHS host communication reliability
- by detecting when a distant host is down.
-
-
- Syntax:
-
- Install PING as an MHS gateway with the PGINST batch file, and
- run PING manually to display statistical information.
-
- To install PING as an MHS gateway, invoke the PGINST batch with
- the name(s) of the MHS host(s) you want to test automatically.
- For example "PGINST FARHOST" will install the PING gateway and
- test host FARHOST.
-
- To add or delete hosts to be tested once PING has been installed,
- run the MHS directory manager and add or delete hosts names in the
- "Gateway commands" field for the PING gateway.
-
- Here is an example of a statistical output displayed when manually
- invoking the PING program (after the gateway has been installed and
- run at least once):
-
- Host name : FARHOST
- Last ping sent : Fri Sep 11 16:38:53 1992
- Average delay : 36 minutes
- Hops (one way) : 2
- Warning threshold: 3 hours
-
-
- The PING gateway can be used in conjunction with the MHS Scheduler
- from Infinite Technologies or other equivalent utilities, to be
- invoked for example once a day. In such case, make sure that the
- PING gateway has a threshold of 1 message.

- Files:
- PING.EXE copied in MHS/MAIL/GATES/PING/PUBLIC as INPOST.EXE
- PING.EXE copied in MHS/EXE
- PING.DAT created in MHS/MAIL/PUBLIC by the gateway
-
-
- Internals:
-
- A dummy user routing is created to route echoes to the gateway.
- PING has only been tested with MHS 1.5 hosts.
- Host CSERVE does not echo any ping (stealth hub?)...
