Question: Destination Host Unreachable 

Forum: PCMCIA Network Adapter Issues
Date: 1999, Nov 15
From: David Walden Walden

I have installed RedHat 6.1 on my Mitac 6020 with no problems except my Wisecom PC400 PCMCIA network card doesn't seem to be talking to the network. I am able to ping the card itself and when netstat -r is run the default gateway is shown, but I am still unable to ping anything on the network. I keep getting a response "Destination Host UnReachable". Does anyone have any suggestions?

Network unreachable == routing problem

Your "netstat -r" may show a route to your gateway, but there must still be a problem with your routing info. "Network unreachable" always means a routing problem. Perhaps your gateway address isn't on the same subnet as your own IP address. If you can't sort it out, post the actual "netstat -rn" output.

Here is my routing table. To me everything works fine.

Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
195.175.107.118 0.0.0.0 255.255.255.255 UH 0 0 0 eth0
195.175.107.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 195.175.107.65 0.0.0.0 UG 0 0 0 eth0

I don't agree that "network unreachable" is *always* due to routing problems, though this is the common reason. My Olicom GoCard multifunction eth/modem card gives this, but /var/log/messages shows the following when pinging an external address (i.e. not itself):

<date> <node> kernel: eth0: timeout waiting for Tx RDC.
<date> <node> kernel: eth0: pcnet_reset_8390() did not complete

and repeats this ad infinitum.

Is this why the Olicom card is no longer in the latest list of supported cards?
