Question: No success with either 10/100 Etherjet nor 3Com cards on Thinkpad 

Forum: PCMCIA Network Adapter Issues
Date: 2000, Mar 01
From: lyle borg-graham lyle

I have gotten the same "SIOCADDRT: Network is unreachable" message with both the IBM 10/100 EtherJet card and the 3Com 10/100 3CXFE575CT card. The machine is a Thinkpad 600E, running Red Hat 6.1, kernel 2.2.14, and using the pcmcia-cs-3.1.11 distribution. Apparently all the network configuration files are ok. I note some bizzare things, such as the ability to ping locally even when the card is not installed.

As perhaps a side note, at some point in this process the cardmgr started sending messages directly to the screen (i.e. "Network unreachable") during bootup, and *not* to /var/log/messages as it did before.

Thanks very much for any ideas!

Lyle

Included below are some (hopefully) useful tidbits (with the 3Com card installed):

I should add that I get the "good" two high beeps when the 3Com card is inserted. Also, it works under Windows.

This is a configuration error

"Network is unreachable" indicates a network configuration error.

These settings are inconsistent.  Assuming your NETWORK and NETMASK
are correct, you should have BROADCAST=128.122.146.255.

Your network.opts file is odd.  You should either specify all your
network settings in network.opts (as above), or replace the entire
file with just the code from the PCMCIA-HOWTO to use ifup/ifdown to
configure the network.  You should not do both: what happens is the
PCMCIA script configures eth0, then does the "ifup eth0", which
re-configures the interface using the Red Hat netconf data.

128.122.154.50 may belong to another machine, but you have also
configured this machine to have the same IP address.  It isn't the IP
address you gave in network.opts, but I'll bet it is the address that
shows up if you run "netconf".  You are pinging yourself; the kernel
knows that the packets don't have to go over the wire, so it works
even when the cable is unplugged.

Progress, but...

Ok, followed these suggestions, and now no "Network unreachable" message. Thanks!

However, I still can't seem to access the network.

Well, the only place that 128.122.154.50 shows up is in /etc/hosts. The above behaviour still occurs with another IP that is *not* in /etc/hosts, in fact as long as the IP has 128.122.*.*. And, if I use a hostname, I get: 

 [ root@cognilap ~]# ping calaf.cns.nyu.edu
 ping: unknown host calaf.cns.nyu.edu
