Re: [foxboro] 2nd Ethernet problem

Cyrus,

How did you ping the other machines? By name or by IP address? If you
haven't done it, try pinging something by its IP address. If you're
successful in doing that, you need to check a couple of files:
/etc/nsswitch.conf and /etc/resolv.conf.

By the way, running 'ifconfig -a' on one of my AW-51B boxes shows the MAC
addresses for le0 and le1 are the same.

Subject: [foxboro] 2nd Ethernet problem


Hi List,
I am having problems getting a 2nd ethernet port on an AW-51B working after
an IP address change.  The plant upgraded their switches and all machines
were assigned new IP addresses, netmasks and default routers.  I changed
the configuration of the 2nd ethernet port (le2) online using the ifconfig
command (IP address and netmask) and everything worked fine for a couple of
weeks.  I also changed the hosts file and the defaultrouter file.  I did
not change the netmasks file.  A couple of days ago the machine had to be
rebooted and since then the 2nd ethernet port has not worked at all.  Can't
ping anything.

In doing some checking I discovered a hostname.le1 file and no hostname.le2
file. The machine has 3 ethernet ports but we have always used le2 as the
external connection.  I don't know where the hostname.le1 file came from.

I changed its name to hostname.le2 and rebooted but this did not correct
the problem.   I then noticed that the netmask was not what I had set it to
a couple of weeks ago and realized I had not changed the netmasks file.  So
I changed that and rebooted.  Still doesn't work.  If I check the setup
with ifconfig -a, everything appears ok except both ports appear the have
the same MAC address.  However I am pretty sure I remember that being the
case ever since the 2nd ethernet port was originally setup many years ago.

To check the cable and switch, I connected my notebook computer to the
patch cord and it was able to ping other machines ok.

I figure that I have missed something on the setup of this port but can't
figure out what.  I suppose that the ethernet card could have gone bad but
that seems unlikely.  If I can't fix it soon, I will try to use le1 but
that is not a twisted pair card so I will have to find an adapter.  Any
suggestions?  Thanks for your help.
