- EHP.1 for etherhostprobe
-
- Ethernet Host Prober:
-
-
- Probes each Internet address in the range starting with ``begin-addr'' and
- ending with ``end-addr'' (both ``begin-addr' and ``end-addr'' can be either
- hostnames or dotted-decimal Internet addresses) by forcing an ARP
- packet to be sent to each Internet address in the range specified.
- Up to 5 ARPs per hosts will be send at 0.25 second intervals.
- This program uses the operating system's ARP tables, and thus may degrade
- performance somewhat while running.
-
- IPF.1 and IPF.2 for ipforwarding: check for hosts doing IP forwarding
-
- Probes each host listed on standard input to see if it is guilty of IP
- forwarding.
- Uses the ethernet interface specified by ``interface'' to send probe
- packets.
- If a ``broadcast-addr'' is supplied, it is used as the IP broadcast address
- in the probe packet, if omitted, the IP broadcast address is deduced from
- the interface address.
- Since this program is ignorant of subnets, the ``broadcast-addr'' should
- be supplied in a subnetted environment.
