eth between two computers

[Matthias Schulz <matthschulz1@worldnet.att.net>]

I'm trying to make a ethernet-connection between two computers in order to 
replace the up to now used plip.

I put in the laptop a linksys PCMPC100 an it got recognized immediately.
I put in the desktop-machine a linksys LNE100TX, compiled the supplied 
drivers and put the results pci-scan.o and tulip.o into 
/lib/modules/2.2.17/net.

I took the plip down and fired up the eth up with:

>ifconfig 192.168.0.3 eth0 up at one side and
>ifconfig 192.168.0.1 eth0 up at the other side.

I can ping each other:
ROOT> ping 192.168.0.1
PING 192.168.0.1 (192.168.0.1): 56 data bytes
64 bytes from 192.168.0.1: icmp_seq=0 ttl=255 time=0.7 ms
64 bytes from 192.168.0.1: icmp_seq=1 ttl=255 time=0.4 ms
64 bytes from 192.168.0.1: icmp_seq=2 ttl=255 time=0.4 ms
64 bytes from 192.168.0.1: icmp_seq=3 ttl=255 time=0.4 ms
64 bytes from 192.168.0.1: icmp_seq=4 ttl=255 time=0.4 ms
 
--- 192.168.0.1 ping statistics ---
5 packets transmitted, 5 packets received, 0% packet loss
round-trip min/avg/max = 0.4/0.4/0.7 ms

Then I checked:
ROOT> route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.0.0     *               255.255.255.0   U     0      0        0 eth0
ROOT>

This is the same on both ends.

Then I tried :

ROOT> route add -host 192.168.0.3 on machine "a" which should get 192.168.0.3
SIOCADDRT: No such device
ROOT> route add -host 192.168.0.1 gave me the same result
SIOCADDRT: No such device
ROOT>

I read the NET3-4-HOWTO but got no clue.

Anyone else a tip for me?
