Morn, World! I am looking for software ( freeware, shareware, payware ) packages which will do the following: Monitor all net tracfic in a LAN, across as many protocals as posible ( including DECNet ) Ability to filter on a single protocal, packet, host for reporting Generate reports on net usage Wanted, but not needed yet: grab & look at a single packet It would be nice if it was not dependent on any given platform ( I know, DECNet is only for VMS & ULTRIX ), as my manager uses a NeXT & VMS, while I use ULTRIX. Any help would be appreciated. I will be more than happy to post/mail my findings after I get some! Don -- Donald M.

You can pick up the sources from gatekeeper.dec.com:/pub/net/tcpdump-2.0.tar.Z It also requires Ultrix 4.0 or later (and with Ultrix 4.1 requires the patched if_ln.o). For all such promiscuous mode applications on Ultrix, you will need to rebuild your kernel to include the "packetfilter" option, and you will need to use "pfconfig" to authorize use of promiscuous mode. Both tcpdump and NNStat basically understand IP; if you want to debug DECnet problems, they are less helpful. (I've been thinking about hacking on tcpdump to handle DECnet packets, but this is trickier than it seems.) > It would be nice if it was not dependent on any given platform ( I >know, DECNet is only for VMS & ULTRIX ), as my manager uses a NeXT & >VMS, while I use ULTRIX. > Any help would be appreciated.
