Ethernet Cards and Hubs


I've got a small donated network of 10 computers setup as a Linux Lab for people
who want to learn about Linux, including me.
I mainly use it to migrate MSOffice apps to Open Source, and to NFS load linux
on donated hardware.
This is where my problem started. I have a SynOptics LattisHub 2804 and 10 PII 400Mhz
computers running RH7.2 over 10/100Mbps Ethernet cards, using DHCP, NIS, NFS, HTTP et al
No Problemo here. But when I attempt to connect a machine for Linux network install running
a 10Mbps card, I can ping it, but no NFS.
Obviously the Hub is a 10Mbps and all 10/100 cards are running at 10Mbps.
Everything else works as it should, and all config files are correct. I even talk to Windoze
via MyOBDC.
What am I doing wrong?

So, are you saying that only 1 of the cards is having this problem?

And nfs uses port 2049. do you see it listening when you type 'netstat -an' ?

Regards,
Peter

what I am saying is that 100/10Mbps cards work but 10Mbps cards dont.
I'm at home being sick at present. I will visit the lab on Monday and have a look at the port.
I will check 10Mbps cards on active systems to see if the problem is just in the RH install floppy.
Thanks for your help

Thumbs down ethernet cards and hubs

I having fun with this one, yeah the port is okay, but I'm using donated equipment and the 2804 and 2803 hubs may be faulty. I've got a 2804 which seems to work fine until I switch on the link port, then all sorts of errors.
I'll have to find a known good one, before I can do anymore useful analysis.
As they say in good old oz b.....r.
