Ask whoever is responsible for the Sun system if they have applied all
of the patches to it released by Sun. Spcifically, there was one
reciently which dealt with this issue as Sun had optimized their
system only for fast ethernet links and this caused the slower
PPP/SLIP style links to suffer needlessly.

The patches are on the normal Sun archive sites.

I don't think this is a sun problem, since this only happens on Linux 2.0.13.
When I use 2.0.0 everything is okay. Btw. i am connecting via 10base5 Ethernet
not via PPP/Slip.

[transfering data from ftp.informatik.hu-berlin.de is slow]

Quote:>read(7, "\37\213\10\10\262Dt2\0\3ls-lR.ma"..., 8192) = 512

^^^^^^^^^^^

Can someone out there please test, if this happens with Kernels >2.0.13?

Greetings,
