Try turning off any automatic checksumming features on the interface.
What you are describing typically occurs when a network interface
starts dropping or mis-checksumming certain packets.
Other possibilities include: long or fragmented packets being
improperly blocked or erroring out.
Hm, it's very strange. "w3m" (a text browser) actually works like hell,
while "fetch" doesn't work. When I open the same page (your Hammer patch
diff for example) in w3m, it appears immediatly, while when I try to
fetch it with "fetch", it gets stuck in
#fetch -v http://apollo.backplane.com/DFlyMisc/hammer02.patch
looking up apollo.backplane.com
and nothing further happens. So it seems to be a DNS problem.
But I thought they all are using the same resolver library.
This only happens in this local net here, regarless whether I use the
wireless card or the built in ethernet. Other operating systems work
fine (I tried FreeBSD and MacOSX).
Any further hints what this could be?
