Re: TOP Network Interface Port of a Sun Ultra 30


Hi again, Don!

You'll have to set the addresses of the serial port hub to the
working range of whatever they are connected to -- but you can
hopefully prevent the hub from originating connections to the outside,
and *hopefully* your D-Link does NAT (Network Address Translation) of
outgoing connections so the outside never sees your internal IP
addresses, even if the hub does connect to the outside (such as to
report home if it is one of those systems which likes to call home).

My old D-Link router (where I had had time to read the manual and do
things with it) definitely did NAT. I an nearly certain that this one
does, too. (The D-Link is primarily my firewall. And, I very much liked
the older one.)

But, I will verify this.

I've been suggesting the QFE (Quad Fast Ethernet) card, which
has four hme style ports. In searching for one on eBay, be careful not
to get an sBus version, since it won't work in your current computer, or
the new one which you mentioned below.

Heh heh... I know. :-) I've seen (well, HEARD OF) cards that had 2
and cards that had 4 ethernet ports. That's what I meant by AT LEAST 2
more. :-)

Would there be a significant speed difference?

My *guess* is no.

I have also asked this question of a coworker today, who seems to
know a lot about this. He also said no, it wouldn't be.

Note that the hard drive is an IDE one, not a SCSI one, so you
can't use your old drives from the Ultra-30 (I don't know what size they
are), and the IDE is not as fast a drive as the SCA SCSI interface in
the Ultra-30 and Ultra-60. (Of course -- you could add a PCI card which
can handle one or two SCSI busses out the back of the computer -- but
you'll need housings for the drives too.

Not being able to use the hard drives would be okay.

I now have 2 hard drives in the Ultra-30. It was given to me with a
4.2 G drive. Just nearly 2 years ago, I installed an 18.2 G drive.

I really don't have much on the Sun. (The Linux is the system where
I have a LOT of personal things.)

I "made do" with the 4.2 G for a few years. I expect the 9G one in
the Ultra 5 would be okay.

Note that you can run an Ultra-5 stood on edge. I ran mine that
way beside an Ultra-10 when it was one of the two web servers (now I
have another Ultra-10 for that location), and the firewall was on an
Ultra-1.

Thank you! :-)

Yes -- and since it is showing up as hme1, it should work in
there too.

Would I be able to take the PCI card from the Ultra 30 and put it in
one of these PCI slots?

Yes.

If so, that would allow it to have two network
ports!

Or -- five if you got a QFE card instead. :-)

:-D

So, it appears that I could have 2 network ports with the Ultra 5, if
it is indeed working.

The remaining question is how much do you need to do to move
everything which you are doing on the Ultra-30 to the Ultra-5. Note
that you can't simply move the drive(s) from the Ultra-30 to the
Ultra-10 (wrong interface, and even with a SCSI PCI card you can't
*boot* from the SCSI drives AFIK.

Yes. I DO NOT have much time right now.

Now, I really don't have that much that is "personal" on the Sun. I
did install a "top" command, because I used to log on to it every day from
the Linux and leave it running in a window. I was going to look into
compiling Bacula on it. I have two USB external hard drives on the Linux
computer. And, I was thinking I could do a backup of the Sun via Bacula,
too. I hadn't finished that.

There is a tape drive that was given me with the Sun. I have only
one tape. I HAVE done a backup on it, using ufsdump. (That was primarily
to have my sendmail and router/network configuration files, primarily!)

The worst thing for me would be configuring Solaris 9 from scratch.
Not that that is horrible; in fact I would normally consider that great!
I just DON'T have much time right now...

I'll keep this in mind. Tomorrow (Friday) is the only night of the
week that I sit up late. (Saturday is the only day of the week that X-10
doesn't get me up at a particular time, where it's 3:30 on weekdays and
5:00 on Sundays.) :-) I may look into it, although I have other things
that I also HAVE to do tomorrow night...

But, I guess I'm still considering whether I may want to get a QFE
card or new motherboard. Those aren't expensive. However, this,
money-wise, may not cost anything. (On top of the things I've been
replacing, this is good...)

Note also that an Ultra-5 and an Ultra-10 have the same system
board, and maybe even the same CPU, depending on age. The Ultra-10 is
tower style, and it has more room -- especially for a fancier graphics
card like the Creator-3D. There is the bus connector in the system
board in the Ultra-5, but there is no room to mount the card, and no
place for the mounting bracket. If you want to do pretty graphics on
the system, you will probably eventually want the Ultra-10 and the
Creator-3D card with it. The built-in VGA connector on the Ultra-5/10
system board is rather limited -- lots of colors only at the lower
resolutions, lots of resolution at fewer colors.

Okay, thank you. I hadn't even considered that...

Not that this is very critical to me, either. I use my Linux system
a LOT more for this type of thing. The Sun truly was just a mail host and
a router for the Linux system. That is the only thing I COUNTED on, and
it COULD NOT HAVE BEEN BETTER for that! It ran... and ran.. and ran! :-)
