sun ultra 1 ethernet connection

I have a SUN Ultra 1 workstation. It has a onboard ethernet and I saw the ethernet connector. When I issue the command: ifconfig -a. I only found lo0. there is no hme0. Is there anybody know how to config the ethernet on Ultra 1? Should I see hme0 for ethernet device? Thanks.

This depends on the system board you have installed. If you have a 15 pin Ethernet connector to the left of the RJ45 and a 50 pin SCSI to the right of it then you only have a 10 base-T interface le0.

If you have a 40 pin MII connector to the left of the RJ45 and a 68 pin SCSI to the right of it the you have a 10 base-T / 100 base-T hme0.

The Ultra 1 was produced during the transition from 10 base-T (le0) to 100 base-T (hme0) for more info check the 5 different versions of Ultra 1 in the Sun System Handbook -> Desktops/Workstations section. In the EOL (end of life) section, click on different models of Ultra 1. Then click on CPU Board to see which ones have 10/100 base-T (hme) ethernet.

actually, I don't care if it's 10baseT or 100 baseT. I just want to use it to connect to other machine or let other machine link to it. Can I configue lo0 the same way as sme0? the how about the 127.0.0.1 address? can I setup virtual hostname to use more than 1 IP on the same ethernet connect? Thanks for help.

No. You cannot use lo0 as this is not a phyisical device. You should have an hme0 or an le0 in addition to lo0. What does watch-nets show you at the ok prompt?

at OK prompt command banner return result of netowrk device:

command prtconf return:

Have you created an /etc/hostname.le0 file yet? It typically contains the hostname of your system, although it may be different if you're planning on using multiple network adapters.

To "activate" a network card on a Sun system, there needs to be a file called /etc/hostname.[device/number]. The type of device you're using various on platform or ethernet card.

for example:

/etc/hostname.le0

/etc/hostname.hme0

/etc/hostname.dmfe0

Good luck!

Thanks jds2n and spamly for all the suggestions. I just configured network and it worked.

Now I am try to add a unipack external hard drive to the box. I checked my ultra 1 box has only 50 pin SCSI connector, but unipack has 68 pin SCSI. I heard some SCSI 50 pin to 68 pin converter. But I am still not clear about that. If I use a 50 pin to 68 pin converter, is that hard drive going to work? There are different kind of converter, some are internal converter, some are internal to external converter. What's the difference between them? which one should I use? Hope to get help again. Thanks.

IF the disk is single ended then you can use a 50<-->68 cable: http://sunsolve.Sun.COM/handbook_pub/Devices/Cables/530-2115.html
