How to analyse slow LAN connection?

Hi all

How can I systematically analyse what is wrong with my LAN between Red
Hat 9 Linux 2.4.20-8 and Win98?

I am getting 50kb/s over a direct LAN cable with proftpd-1.2.9-1.9 on
xinetd.

My Linux networking knowledge is limited, and I have probably made a
mistake in the setup.

Many thanks!

Bernard



In my proftpd.conf I have added:

UseReverseDNS off
IdentLookups off

but this did not improve speed.

/etc/resolv/conf:

search localhost
nameserver 203.96.16.35
nameserver 203.96.16.36

These nameservers are on the internet but not accessible because
currently the computer is not connected. If I connect via modem then
there is no improvement.


/etc/sysconfig/network-scripts/ifcfg-eth0:
DEVICE=eth0
BOOTPROTO=static
BROADCAST=192.168.0.255
IPADDR=192.168.0.4
NETMASK=255.255.255.0
NETWORK=192.168.0.0
ONBOOT=yes

You could try installing tmdns (It's a lightweight dns for tiny LANs.)and
point your windows dns to 127.0.0.1. The question is what point dns on a
192.168 lan?


Most of the windows network configs I've seen are a jumble of netbios,
netbeui, QoS, netware and every other service and protocol ppl throw at the
system. Just use TCP/IP and nothing else. Windows is stupid enough as it is
without complicating it with bolt-ons that confound it ad infinitum.
