In an attempt to learn more about Local Area Networks, I have set up a 
simple three machine net but am experiencing some difficulty and I 
wonder if a more experienced person could please help.

The configuration is:-

Machine 1
Pentium 3 running Windows 98 as IP 192.168.1.1 (alias windows)
Network card SMC EtherEZ 8416

Machine 2
Pentium 2 running Mandrake Linux 7.1 as IP 192.168.1.2 (alias linux)
Network card Genius GF100TXRII

Machine 3
Pentium 1 running Mandrake Linux 7.1 and Windows 98 as IP 192.168.1.3 
(alias compaq)
Network card Realtek RTL8029
This machine also has an internal 56 k non-Win modem and a connection to 
the Internet.

The machines are connected to each other via a base10 hub with short 
twisted pair cables.

The physical installation seems ok as I can ping any machine from any 
other and get fast return times.  The problem I have, though, concerns 
machines 2 and 3 whose configuration was intended to be identical.

Using common log-on user names and passwords and with the Compaq machine 
as my workstation, I can log on to "linux" and ftp files to and from 
that machine.  Further, I can download files from the Internet and then 
pass them to "linux".

So far so good.

If, however, I reverse the arrangement and try to use "linux" as my 
workstation, I can connect briefly to the Compaq machine but the 
connection times out in two or three seconds and if I use ftp at the 
command line, I get an error message "421 Service not available remote 
server has closed connection".  gFTP reports that I am already logged on 
and then waits for 30 seconds before trying (unsuccessfully) again, even 
if "compaq" is waiting for a log on of some kind..

The /etc/hosts.allow and /etc/hosts.deny files are blank on both 
machines apart from their comments and there are no entries in 
/usr/sbin/tcpd file either.

Before I tear out what remains of my hair, I wonder if someone could 
please point me in the right direction.

Thanks for any help offered.
