Hello all,
I'm having the following problem. I have a Win95 PC in a WAN, and a Linux
WINS. For the local subnets there's no problem, but the WINS seems to react
very slowly for the WAN pc.
- both WINS and win95 have the same workgroup; the workgroup is not in any
computer name (as far as I know and can see)
- ICMP echo about a 35 msec reply
tcpdump shows a couple of 137 < - > 137 tries, and then finally starts
something else (which is, probably, the browselist exchange or so):
19:31:14.207839 145.99.132.3.137 > 145.99.70.68.137: udp 50

19:31:37.437839 145.99.70.68.137 > 145.99.132.3.137: udp 74
... couple of more, no reaction...
then (the 1st one puzzles me, might be a bug in tcpdump -r <filename>):

... etc.
... and there is the browselist.
Does anyone got a clue? Is this due to the ping times? (This behaviour
first showed up after a software upgrade in our ADSL modems, which
introduced latencies of 70ms and more. Some weeks ago these were cut down
to 35ms and browsing seems to work slightly better).
