check you /etc/resolv.conf file, and make sure your name servers are
listed (these will usually be your ISP's nameservers).
check 'man resolv.conf' for more info.

Actually, I had one case where the current EGCS generated really
faulty code (this is a fragment from it):
frame=3D0;
for(p=3Dlist_start; p; p=3Dp->next)
{
if(p->type=3D=3DtagShowFrame)
{
frame_array[frame++]=3Dp;
}
}
When actually run, EGCS did't generate any code for the frame=3D0 line,
resulting in huge memory corruption problems (it doesn't notice that
a local variable is re-used if the reuse is in the context shown and nowh=
ere
else, so it decides to remove the redundent (as it thinks) frame=3D0 line=
=2E That's
great......I had to include another use of frame later on to ensure it wa=
s set
to zero correctly (this happened even with no optimisation at all - mega =
bug).

Phil,
A book 'The Linux Network' IDG Books ISBN 1-55828-589-X would very
likely help you out. It's written at a novice level starting with a
good explanation of how things work, assuming very little knowledge.
It includes a Slackware linux distirb on CD and, better, some of the
many config files which you can simply copy and then amend for your
machine names/ip nos and so on. The text of the book explains which
parts to change and why (although it skips through sendmail just
telling which bits you must change).
Aside from this, is your network at the stage where you can ping each
machine from the other, and can you do this by machine name as well as
ip address?
On the linux box the details should be in /etc/hosts. There should be
an entry for the win box like
192.168.0.1 windowsbox windowsbox.mydomain.com
You should then be able to refer to the windows machine as 192.168.0.1
or windowsbox or windowsbox.mydomain.com
check the file /etc/host.conf it should look like
order hosts,bind
this tells the machine to look for a name/ip address in the file hosts
and then via DNS if the hosts file doesn't have an entry.
you should be able to get a response by
ping 192.168.0.1 or
ping windowsbox
on the windows machine you should be able to ping the linux box by
ping <ip_address of linux box>
to be able to use the name of the linux box you need to edit or create
a hosts file in c:\windows. This is the same as the linux file
/etc/hosts
192.168.0.2 linuxbox linuxbox.mydomain.com
with this you should be able to ping the linux box
ping linuxbox.
If this doesn't work, nor will samba
Samba
Things to check - windows
Install a network client - choose client for microsoft networks
In windows|control panel|networks|identification see what your
workgroup is called or name it.
In protocols select tcp/ip and netbeui
the client/properties tab should not be set to logon to an NT domain.
choose restore network connections if you want.
Make sure that tcp/ip is bound to your network adaptor
set the properites of the tcp/ip protocol
specify the ip address your box will use. Make the subnet mask
255.255.255.0
set the gateway to the ip of the linux box.
disable WINS.
You may not need to do the following if you do then nmbd isn't working
properly
in c:\windows create lmhosts. This looks like the hosts files above.
192.168.0.1 mylinuxbox
i.e ip_address and name of the linux box.
linux
create yourself a userid. Use this also on your windows box.
In smb.conf look for a line workgroup=xxxxx and make sure it's set to
be the same as your win box.
find a line hosts allow =
make sure this is correct and that the ip of the windows box is in
here.
Look at the section marked [homes]
it may say browseable =no, if so change this to yes.
To test the config file run testparm from the samba installation
point.
to test on linux run smbclient -L machine name
you should see the time &date
timezone
domain os server
a list of shares created and the type
homes Disk Home directories
....
I've never set up printers so I can't help much there.
Samba can be run from inetd or as a standalone daemon.
to run standalone the commands are smbd -D
and nmdb -D
You should now be able to see the linux box from windows.
Go to dos and type net view \\name of linux box.
you should get a less detailed display like from smbclient above.

Did you set up DNS Servers in the kppp setup? Or you can edit
/etc/resolv.conf directly.

I have nearly an identical setupo and problem. My ethernet card is
3Com509b in both machines. My network does work under Win98, so I fell
confident it is software. Any ideas for me?

Still I insist on the fact that your eth0 and eth1 are configured with wrong
IP addresses, due to the fact that 192.168.1.0 network with netmask
255.255.255.0 is superior to the network 192.168.1.0 with 255.255.255.128.
Think about changing IP address of one of the cards, but can't really
suggest particular address without knowing your router's IP information.
Good luck!

You can check for IP address in user's profiles and if IP is not the one
that allowed, just kill user's login process (you may look at 'echo $$'
