Hi I hope somebody can help me.
I have asked this before - and dispite helpfull suggestion I STILL cannot get
my network configures.
My System WILL look like this - assuming I can get the machines to talk to each
other.

What I want to do is make the ether-net connection.
I have in /etc/networks :-
loopback 127.0.0.0
radio-net 44.131.0.0
ether-net 192.168.1.0
on both machines
I configure the ethernet devices with
/sbin/ifconfig eth0 192.168.2.2 \
netmask 255.255.255.0 \
broadcast 192.168.1.255 \
up
on pc_1 and
/sbin/ifconfig eth0 192.168.1.1 \
netmask 255.255.255.0 \
broadcast 192.168.1.255 \
up
on pc-2
I do,
rout add ether-net eth0
on both machines and then I get the following on pc-1

Can anyone explain and hopefully give and answer as to how to correct this,
I am referring to the 1372 under the MSS col.
I cannot get to the other side of the ether-net and if I do a ping -f
192.168.2.2 (local to pc-1) I get nearly 100% packet loss, if I do ping
192.168.2.2 all the packets return without error.
I should say the pc-1 is running 1.3.23 with the WD 80*3 driver complied in -
not a module and this device is at base address 280 IRQ 10 and successfully
works under MSDOG, both ways to pc-2.
The other machine is running 1.3.73 and all appears ok even the kernel routing
table which reports the correct MSS size 1500 (if that is correct :-) ).
Each machine has the same type of card installed a WD8013EPF made in 1992 and
they both have no boot rom.
I would appreciate any help as this now getting the better of me and should
have been quite simple to setup.!!!
