Hi Don!

O.K. I also believe that it should have NAT.

Yes, it does.

Okay... catch you up again! :-D So much is happening every day!
:-O

I ordered my ESP-16 MI 16-Port Serial Hub for next day delivery,
and it arrived this afternoon. (I wanted to see if by some chance I had
time to start learning how to use it and see if I could get any serial
connections hooked up...)

O.K.

I don't have all my adapters yet. Most of them do not have Ethernet
cables, not that that is that big of a deal. But, I have a variety of
adapters (that are here and are still coming) that are RJ-45 to DB9 (male
and female, DTE and DCE) and DB25 (male and female, DTE and DCE). (I
actually have a variety of serial connectors, some of all of the above,
which I had adapters to convert into DB25 DTE.)

The manual gives an Internet address to address it from a web
browser. I plugged it into the fourth computer port of my D-Link router.
(The guy at Avocent said it should work there.)

At the moment, I am not successful in communicating with it. But,
when I log on to the D-Link router, it indicates the MAC address (it
matches what the device says its MAC address is). So, it appears to be
powering up, and the D-Link router knows about it! :-)

At the moment, I am not able to access it. But, I have never tried
to access something that was also to be on my LAN (and NOT on the
WAN/Internet) that was plugged into one of the ports of my D-Link router!
(My last one had four computer ports, too.)

No help there, since I have never used one of those.

I'll continue learning about it, and try to figure it out.

I still have lots of serial devices to check, around the house, when
I get the serial connections again! :-)

Check them with the loopback connector (pin 2 to pin 3) and you
don't need the computers working to be sure that the terminals work.

Not familiar with "Bacula". If it is for Linux, and is similar
to other things which I have been interested in, you have to download and
compile a bunch of libraries before you can compile the program itself.

It is a backup system, with network backup. It can be installed in
Windows and lots of Unix systems. And, yes, there is source code I had
placed on the Sun, and I had compiled it! But, I hadn't gotten MySQL to
work, the last time I had a chance to see if I could get it going...

O.K. I use amanda for backup software.

Hmm ... what kind of tape drive? Sun has used a lot of them
over the years. For an Ultra-30 (assuming that your tape drive is
contemporary with the computer) I would expect perhaps either a DAT
drive or an Exabyte. (Exabyte will use 8mm tapes like those used in
camcorders. But tapes are not interchangeable between all kinds. The
8505 drive would read anything older (back to the original Exabyte 2.3
GB 8200 and up to about 7GB with the right tapes. Then there are the
Mammoth (up to around 40GB with the tapes made for it), and the
Mammoth-II (up to around 60 GB native or 150 GB with the drive's
built-in compression). You need to do a little work in the
/kernel/drv/st.conf file for the Mammoth-II, but the plain Mammoth (also
called the 8900) is supported normally. I don't have that much
experience with DATs -- except for audio work, not computer backups) so
i can't tell you as much about them.

Yes, it is an Exabyte. And, the one tape I have is an Exabyte 8MM
Data Cartridge, 112m.

It was given to me with the Sun. I purchased a cable on Ebay, and
one tape! :-D

Hmm ... you haven't told me what Exabyte it is. Let's go for
the easy thing to check. What color is the tape cartridge?

1) Black Older Exabyte up through 8505 -- cartridges for this
should be dirt cheap on eBay -- and you can also use
8mm video tapes with some loss in reliability.

2) White Mammoth -- moderately expensive on eBay, sometimes
real bargains available however.

3) Blue Mammoth-2 -- very expensive most of the time on eBay.

There are some differences in the way Solaris 9 is set up, and
quite a few in Solaris 10. Most of the stuff in /etc/init.d and in
/etc/inetd.conf have been moved to a different program to maintain them,
though some still have hooks in /etc/init.d for ease in turning them
off. For example, sendmail has the following (in part):

Okay... here is what I decided...

I still have serial devices to check.

With the loopback connector so you don't need anything else
working to check the terminal.

I just purchased a QFE card, just now, from Ebay. A "buy it now"
from weavh, with 100% positive comments. I just paid for it, via Ebay,
and they'll take it from my checking account.

It is a 501-4837 X1049A SBus Sun Quad FastEthernet Card.

When that arrives, I'll put it in a PCI slot in the Ultra 30.

No you won't! Unfortunately, the 501-4837 is the Sbus version
of the card -- and it won't fit in the Ultra-30. You need one of:

501-4366
501-5406
540-4094

the PCI versions to use in your Ultra-30. What you got can be used in
systems up to the Ultra-2 -- no later machine has the Sbus for it to
plug into.

I believe that I gave you the numbers to look for in an earlier
posting.

(The
one network card that is in there is currently the only thing that is in
the PCI bus in the Sun! The Linux is full, though the next time I power
it down, I can remove the Cyclades PCI card and have one slot available
again.)

O.K.

This way, I'll be able to use the exact same Solaris that I already
have configured. I have one backup (currently) of my files, mainly for
the sendmail and configuration.

Just by renaming the hostname.hme0 and hostname.hme1 files to
hostname.hme1 and hostname.hme2 -- once you get the *right* QFE card.
Note that the PCI QFE card has LEDs to verify connectivity for each
port.

I expect the thing that I'll mostly have to work with that will be
different is I'll have additional hme ports, and I guess I'll be ignoring
hme0.

Yes -- and you could make a direct connection to the serial box
from one of those -- but you would have to edit some files to make it
work.

I will plan on using one for the D-Link router (and cable modem,
through it), and I'll plan on plugging my ESP-16 MI 16-Port Serial hub
into another of the ports on it.

(Hmmm... if it is faster, I may benefit from plugging the Linux
system into a third of the ports... Or perhaps the Linux network stuff
being in a different PCI slot would be better...)

I have in the past preferred "hard coded" static IP addresses for my
local network devices, so I'll likely try to set that up as well.

O.K.

I will appreciate your help, when the card arrives, to help me not do
anything too stupid. :-D

Unfortunately, it is too late for the first opportunity --
you've already bought the wrong version of the card. You'll see when it
arrives. :-(

BTW I keep having the feeling that we've interacted before -- whether on
this newsgroup or elsewhere.

Well, looking over printouts of some USENET and emails in my Sun
folder, here is one from dnichols@xxxxxxxxxxx, on Oct 15, 2006, subject
"Have a new 18.2 GB Sun hard drive, would like to keep the current 4.2 GB
drive in there..."

:-)

Ah, the new drive I put in it "nearly two years ago", I believe!

Yes, we have. And, actually, I also have that feeling. The only
other thing I believe I've ever posted or "made myself known" regarding
the Sun is, I believe when I was opening the Sun to put the new hard drive
in it, the phillips screw in the back got really messed up! I purchased
penetrating oil, and that got it! But, I had to really work with it! It
was so messed up that screwdrivers weren't working any more! :-)

Yes -- I found both of those when looking for other old
articles.

Do you read or participate in any Linux hardware or other newsgroups?

Not any linux-specific groups -- but rec.crafts.metalworking and
a little in rec.music.makers.squeezebox.

Enjoy,
DoN.
