I'm looking for a protocol analyzer. It needs to be able to handle a large number of protocols and yet still be fairly inexpensive. I can't give an exact price range yet as I don't know my budget yet. If anybody has any suggestions please post them here. my location will be changing soon and I'm not sure what path will be needed to reach me. Thanks in advance, Thomas Fout aka TRouT

We recently purchased a protocol analyzer for less than $5K. It is a "roll your own" and consists of a Toshiba T3200 (any fast AT-class portable with expansions slots would do), a Micom/Interlan NI5210 and FTP Software's LANwatch. I am very happy with it. For an inexpensive solution, I think it really has worked out well. The commercial boxes (Sniffer and LANalyzer) cost $15 to $20K and have some cuter features such as bar charts showing network packet rates, etc, but as for being able to pick up packets at a high rate and look at them in detail, I think my solution is just as good. FTP even provides hooks for you to be able to write support for your own protocols. It comes with code that supports lots of protocols. You would have to talk to them about what is in the current distribution.

You supply the PC and the network interface. Spend more on a fast PC or network interface and it will perform better. It understands IP well, Chaosnet, DECnet, XNS and 802.2 headers less well. We supply source for packet filtering and parsing routines with the product (needs Microsoft C to re-build it), so you can add specialized packet types, etc. The current version comes with more filter/parsing routines than will fit in a single executable, which we will fix in the next release. We sell it for $1200 quantity 1. There is also the MIT/CMU Netwatch program, distributed with the PC-IP public-domain TCP/IP package. It doesn't have much in the way of packet parsing or symbolic filters, though. James VanBokkelen FTP Software Inc. (617) 868-4878
