Hello there,
I am trying to setup a 2 machines TCP/IP LAN. I have read carefully
the NET-3 HOWTO and the Intranet HOWTO (among others), and I think I
followed all indications. It doesn't work, I have no clue where to
investigate further the problem, so let me say a bit more in case some
good soul in here could suggest me something.
As you'll see below, it seems that about EVERYTHING works (including
the hardware), except than I cannot even ping a machine from the other
:-). If someone could suggest me further tests to help me identify the
problem, I'd be grateful.
Set-up:
- one machine is named "phat" (IP 192.168.1.1), has RedHat 5.0
- the other is named "admin" (IP 192.168.1.2), has Win95 with MS-TCP/IP
- local domain name is corcise
- netmask in both machines is 255.255.255.0
What doesn't work:
- I cannot successfully ping phat from admin or admin from phat (and
so no other networking works either).
What does work:
- DNS looks OK, on both machines the name addres is resolved into the
right IP address (phat=162.198.1.1, admin=162.198.1.2); I've set a
netmask of 255.255.255.0 on both machines.
- the hardware looks OK, as the LAN does work if I boot phat in Win95
(NetBeui LAN);
- I can ping localhost fine on both machines
- when I ping phat on admin, ping fails (times out), but the phat LAN
adapter led blinks in rythm with the ping packets sent (also true in
the other way, ie when I ping admin from phat).
- on phat, some command (I've forgotten which one), that reports bytes
sent to and received from an interface, reports the bytes sent when
I ping admin from phat; and the bytes received when I ping phat from
admin
- also note that I did manage to make the link work some months ago
with the same hardware (some guru no more available made it work
using forgotten incantations).
- I connect to the INternet fine with both machines (each has its modem)
Some outputs on phat (the Linux box):
/home/jacques 1010 # ping admin
PING admin.corcise (192.168.1.2): 56 data bytes
[hangs; then when interrupted reports:]
--- admin.corcise ping statistics ---

Don't hesitate to ask me for more information in case you think it
could be useful.
Any help appreciated,
