ear all,

we have severe network problems within our environment consisting of

- HP ProLiant ML370 system running SLES8, Service Pack 2a
- Broadcom BCM5700 Gigabit on-board chip ====> eth0
- Intel Pro 100 Dual Server card ====> eth1, eth2

Here is our network configuration:

eth0 Link encap:Ethernet HWaddr 00:0B:CD:6A:8B:B5

We can establish any connection into the 192.9.205.0 net but trying to
get a system in the ...206... net, for examples

telnet 192.9.206.2

then this appears

telnet:connect to address 192.9.206.2: no route to host

This worries us since the routing table (netstat -r) seems to be o.k.:

Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
149.243.226.0 * 255.255.255.0 U 40 0 0 eth0
192.9.205.0 * 255.255.255.0 U 40 0 0 eth1
192.9.206.0 * 255.255.255.0 U 40 0 0 eth2
default 149.243.226.1 0.0.0.0 UG 40 0 0 eth0

For analysis reasons pls. also see also the following ouputs:

cat /proc/interrupts

Well, there isn't is there! Look at the stats and you'll see that,
although the interface is up, it's received no traffic ( RX bytes:0 ).
Either the cable's cut, or the port at the server or switch end is
damaged.
