Two RedHat 9 PCs lan. Can't ping each other

Hello,
I'm trying to build a mini-lan with the two PCs I have at home.

-I connected the two ethernet cards with a crossover cable
-I assigned to the PC_1 the address 192.168.0.1 (ifconfig from command line)
-I assigned to the PC_2 the address 192.168.0.2 (ifconfig from command line)

Here's a fragment of what I see with ifconfig:


PC_1:
eth0 Link encap:Ethernet HWaddr 00:0D:87:06:64:A7
inet addr:192.168.0.1 Bcast:192.168.255.255 Mask:255.255.0.0
PC_2:
eth0 Link encap:Ethernet HWaddr 00:08:9B:80:88:41
inet addr:192.168.0.2 Bcast:192.168.255.255 Mask:255.255.0.0

And here's what I see with route:

PC_1
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.0.0 * 255.255.0.0 U 0 0 0 eth0
169.254.0.0 * 255.255.0.0 U 0 0 0 eth0
127.0.0.0 * 255.0.0.0 U 0 0 0 lo

PC_2
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.0.0 * 255.255.0.0 U 0 0 0 eth0
169.254.0.0 * 255.255.0.0 U 0 0 0 eth0
127.0.0.0 * 255.0.0.0 U 0 0 0 lo




If I ping 192.168.0.1 from PC_2 I get:

From 192.168.0.2 : destination host unreachable


while tcpdump on PC_1 says:

22:08:03.078106 arp who-has 192.168.0.1 tell 192.168.0.2
22:08:03.078138 arp reply 192.168.0.1 is-at 0:d:87:6:64:a7

Following some replies given to a somehow similar post, I tried
iptables -F on both machines, but it didn't work.


How can I fix the problem?


Thank you!

Well now you know your hardware is talking between boxes.

Humor me, on pc 2
edit this file with /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.0.2
NETMASK=255.255.255.0

and in /etc/sysconfig/network
NETWORKING=yes
GATEWAY=192.168.0.1

Now, do a
service network restart
ping -c 1 -1 192.168.0.1

I assume firewalls are disabled on both boxes.
