- I have something called arpwatch which maintains a database of
- ethernet/ip address pairings. It emails significant changes. (I pipe
- these into a local newsgroup called lbl.arpwatch.) To use it you must
- first install the Berkeley Packet Filter. SunOS 4 is one operating
- systems supported by bpf.
-
- Arpwatch is available via anonymous ftp from ftp.ee.lbl.gov
- (128.3.112.20). Set binary mode and retrieve the compressed tarchive
- arpwatch-1.0.tar.Z; bpf is packaged as part of tcpdump. The current
- version of tcpdump is also found on ftp.ee.lbl.gov in the compressed
- tarchive tcpdump-2.2.1.tar.Z.
