Using tcp  & os/2 on a ethernet lan

I have two pc's capable of running NT

or OS/2. Under nt, tcp runs fine (ftp & 

telnet) Under os/2 I  can use ppp  and
everything works. With ppp down, I  can
ping myself, ftp to myself, telnet to
myself, etc. I cannot ping from an os/2
machine to another pc(whether that
machine is is nt or os/2) I can see the  
ping going on the net (at the hub) but
it times out. From NT a ping to OS/2
also times out. netbui works between
OS/2 and any other pc. So-- tcp works,
the ethernet works but tcp  doesn't
work over the ethernet. I saw a
similiar request in news (w/o an
answer). What have I to do/undo to the
tcp  setup to make it  work.  I have
the 'getting to know os/2  warp 4' book
and "believe" I followed it  correctly  
but obviously interpreted something  
wrong.
  How do I get tcp to work between os/2  
clients on an ethernet????

Use the 'netstat -r' command on both systems,
to make sure that TCP/IP packets can be "routed" from one machine to the other.

Netstat -r was working.  I believe that the problem was in the
ethernet addresses I chose. I suspect that when I changed the
addresses to 192.162.100.whatever (which are only local,
unregistered addresses)-- everthing worked. I had used 192.100
vice 192.162.  In any case now I can ping, telnet, talk, ftp,
etc.  I do have another question. netstat shows my default
gateway as my ppp connection (when I'm up) but from my ethernet
my  other pc can't ping that gateway using its numerical
ethernet address.  Why?

Could your "other" PC be located behind a "firewall" ?  
If so, then PING-style IP-packets could be filtered-out.
Try TELNET or FTP to that gateway.

netbeui has nothing to with tcp/ip,because netbeui by itself is a different protocol, used in a lan. You were not able to reach other hosts on the net(thru lan0,i.e.,ehternet) using tcp/ip probably because of your incorrect tcp/ip configuration.(like ip-addr,subnet mask,and default router.). Make sure you have the correct configuration(see \mptn\bin\setup.cmd). Run
      ifconfig lan0 and see the flags. It should have entr like Up and Running. ping to your broadcast address(which you can see in your ifconfig lan0 output)
      if your machine pings to any other ip-addresses,other than yours,then you can reach any other host on your n/w.If it pings only to your ip-addr,then your tcp/ip configurations are OK but router, subnet mask configurations might be Wrong.

Hope you got it !!!!
