Description Christophe Leroy 2000-09-15 17:20:19 UTC
When connecting to a WinNT workstation, it happens that Linux Box
resets the connection when it receives the ACKSYN from the WinNT box, 
with no reason.

Comment 1 Alan Cox 2000-09-16 21:12:14 UTC
Is this with the original or errata kernel ?

Comment 2 Christophe Leroy 2000-09-18 06:55:54 UTC
It's with the errata kernel 2.2.16-3

Comment 3 David Miller 2004-03-06 07:11:27 UTC
Way past EOL product, therefore unlikely to ever be fixed.
