Hi,
I wrote in a while ago but was advised by Christopher on this list that I
did not provide enought information. So I hope to do better here.
Basically, I am attempting to connect up two box (3.4)in my home. I am
using two different cards 3Com 3c905 (PCI) and 3c509b (ISA). The address
are 192.168.5.5 and 192.168.5.10 respectivly with a netmask of
255.255.255.0 The problem is that I am unable to ping across the boxs. I am
not using a hub thus I am using a cross cable for direct connection.
However when I run one of the box using win95, I was able to ping each
other. Thus I believe that there is nothing wrong with the cards and cable.
Is there something that I might have miss out? Attached is the output of
"netstat -rn" and "ifconfig -a" of each of the box. I have also tried to
run "tcpdump -i" on each of the cards to see what is happening when I ping
the other system. The result is "arp who-has 192.168.5.10 tell Box A". Hope
someone can help me on this. Thanks in advance.
