these packages, available from dnpap.et.tudelft.nl, are concerned with
packet monitoring and network management. The relevant parts of the index
Beholder The newest Network Monitor with SNMP!
DnpapTools Various tools by the DNPAP group.
Gobbler Packet catcher, writting by the DNPAP group. Full featured packet
catcher with many filters, extended packet viewer.
NetCure The Network Monitoring package developed by the DNPAP Group.
Hardware requirements: A fast PC (286 or 386 will do) and a
ethernet card (such as the 3com or wd cards). A color display is
not requirement, but netmon is very beautiful in colors.
Sage SNMP query language based on Scheme, from the famous DNPAP group.
Spectre Host profiling, measures activity and type of activity of a number
of specified hosts on a network.
I'm not aware of PD PC-based routers with filtering (PCRoute doesn't, and
I've never heard what happened with its' commercialization, anyone know?),
but there are at least two bridges with filtering capabilities:
KarlBridge nisca.acs.ohio-state.edu /pub/kbridge
Drawbridge sc.tamu.edu pub/security/TAMU
I'll be interested to see if Novell include filtering capabilities in the
next release of their multi-protocol routing software package; runs on a PC
with multiple interfaces and handles IPX, TCP/IP, AppleTalk & OSI.
