Charlie, KI5XPs email is right on the money. We used to consistently
run 48 hours without problems at K4JA, usually with five or six
computers in the network. The link was NET-DDE not TCP/IP. All the OSs
were the same as were the versions.
When TCP/IP got introduced, many of us jumped on it - and left DNS
enabled. This is a guaranteed recipe for disaster. As Charlie rightly
points out, WL running on multiple computers under TCP/IP with the
bandmap enabled and dynamic addressing will virtually always crash. Any
drop, and there will always be some, will cause DNS to reassign the
TCP/IP address for a given machine and then its crash-city. I can leave
two computers networked here via TCP/IP with low data rate non-contest
spotting traffic moving, no logging going on and no RFI, and they will
seldom stay networked for more than about 10 hours if DNS is enabled.
I have had decent luck with TCP/IP and static addressing on very stable
networks, i.e. no RF problems. I think they finally got PJ2T stable by
shielding all the CAT5, shielding the router, and using static
addresses.
Meanwhile, N1MM and WinTest seem completely immune to these problems....
and they support LPT1, etc.
I'm still a WL fan, but my patience is sorely tested. I can name
several large multi stations that gave up on WL due to WL's inability to
deal with anything less than a pristine network. And that is WRITELOG's
inability to deal with the real world, not the real world's inability to
satisfy WL.
Hal, N4GG
