We're trying to get ODT-NET (SCO's TCP/IP package) up and running on a small office Ethernet. Unfortunately, we're having some problems with it (the local machine can successfully be ping'd, but remote machines can't), and I'm trying to figure out where the problem is. I have a feeling that packets aren't even getting out onto the network cable, but we don't have a network monitor and the boss isn't too eager to drop $2000 for what is probably a one-time problem. We do, however, have an extra Ethernet card and a PC laying around. It would seem fairly simple to write a program that just pulled in data from the network card and displayed it on the screen, possibly with options for hex mode, and perhaps even understanding of some of the more common network protocols to help decipher the packets. Does anybody know of such a program that runs under MS-DOS? PD/freeware/shareware would be best, but commercial wouldn't be too bad as long as the price was reasonable (i.e., cheaper than one of the hardware net-monitor jobs). (Followups to comp.os.msdos.misc, please.) -- Marc Unangst | mju@mudos.ann-arbor.mi.us | Angular momentum makes the world go 'round. ...!umich!leebai!mudos!mju |

You're looking for Netwatch. I recommend that you run it over the packet
drivers, in which case you need Joe Doupnik's version. Fetch the apcket
drivers first, then look in support.txt for information on netwatch...
The Clarkson packet driver collection
Availability
The Clarkson collection of packet drivers is available by FTP, by
archive-server, and by modem. They come in two flavors -- executables
only (drivers.arc), and source+executables (driverss.arc). All of the
following instructions apply to both drivers.arc and driverss.arc.
Mail:
I distribute the packet drivers on a 1.2 MB 5.25" disk, or a 720K 3.5"
disk. You can send me a check for $20, or you can send me a purchse
order and I will bill you for $22. NY residents add 7% sales tax,
overseas orders add $3 for shipping. If you send a check, please be
sure it is in US dollars -- the bank charges me $15 to convert checks
drawn in foreign currencies.
