Diplomat jr Model jrN-ASV User Guide Issue No. 2 (03/01)
28
Depending on the amount of knowledge that is available about the topol-
ogy of the network other IP addresses can be used to test various seg-
ments of a longer path.
If a reply is received this shows that at least the low level drivers at the
Remote Host are functioning. To test that there is an IP stack loaded on
the remote host and that it is alive type ‘E’. This sends an ICMP echo
request (ping) to the Remote Host and if there is a reply the
Diplomat jrN
will display a transit time and produce a beep at the terminal. If another
host is trying to test the reachability of the
Diplomat jrN by sending an
ICMP echo request the
Diplomat jrN will produce a beep at the terminal
when it receives the request.
The BOOTP option remains undefined.
Typing 'R' causes the
Diplomat jrN to broadcast a RARP request. If a
RARP server exists on the network and if it responds with an IP address
for the
Diplomat jrN, then that address will be used as the Diplomat
jrN's IP address.
Network Monitor
There is a low level monitor feature that can be useful under some
circumstances. If the switch BMONIT is set in Configuration Byte B then
the first 60 bytes of every packet detected on the network is displayed in
hex dump format on the terminal. The true packet starts at the fifth byte
as the first four bytes are internal status and pointer information relevant
to the packet. On a busy network the asynchronous port can be easily
saturated.
