(I'm new to Linux and am probably missing something simple, but...)
I think I've got the same problem as Max Klohn (and probably some
others): Samba
transfers TO Windows 98 are uselessly slow (7-8 kb/s) whereas transfers
FROM
Win TO Linux are fast (>500 kb/s).
The network is a P-166 (Linux, "pdlinux.pd.com; 192.168.1.254") and a
P-II-400 (Win 98,
"pdenis; 192.168.1.2") and a crossover cable.
The NIC's are both 3c905B-TX; the driver is 0.99H and Samba is
1.9.18p10.
smb.conf is "out of the [Caldera 1.3] box"
Upgrading the driver from 0.99E and Samba from p8 made no difference.
It's not a cable or NIC problem:
If the Linux box is booted into Win 95 transfers between
it and Win 98 are speedy both ways. The NIC's are set for 10Mb/s half
duplex
[If I try 100Mb/s the Linux xfers are the same and the Win's are >4000
kb/s(!)]
Playing with the socket options [TCP_NODELAY, etc.} had no effect.
Removing the NetBUEI and/or IPX protocols from the Win box did nothing.
==>>> This seems to be a TCP/IP problem: There's a 200 msec pause
between packets.
Thanks for any suggestions.
The following is the tcpdump from transferring the same file back
and forth between Windows 98 and Linux (it's a 42,216 byte file;
"sambafaq.txt", in
fact!). The transfers were done using smbclient get/put but the results
are the
same using Windows copy/paste.
