I need to set up a SCO OpenServer 5.0.5 Enterprise system as an DHCP
Client if possible. I do not see a way to do this under netconfig. I
assume I will need to purchase or download some software to make the SCO
box a DHCP Client.

The system will be connected to the internet via a Ethernet connection
to a SpeedStream 5250 which is a SDSL Bridge.

Thanks,

DHCP client software for OSR 5 was strongly and loudly requested for
inclusion in OSR 5.0.6 during the OSR 5 Birds-of-a-Feather session at
Forum '99.

Welcome to the wonderful world of SCO.
Linux has a DHCP client.
Maybe you can recompile the source and use it on SCO.

I just turfed my SCO and went for the real Unix.

Oh hell, I thought he'd gone.

Just a wild idea at this point, but I was thinking:

Suppose you just did a little Perl script or whatever that
acted like a DHCP client as far as getting the address info,
etc and then came back and did an ifconfig alias with that
address?

Would that answer the typical need? I'm just thinking out
loud; haven't begun to try this, but the issue is going to
come up soon for me, too, because this back-water town is
finally going to get cable internet access, but the machine
needs to be a DHCP client. I could switch to my Linux box
for that, but the one remaining feature that SCO has and
Linux doesn't is Merge, which I need for Quickbooks.

I wonder if that could work?

Interesting idea. Go for it.

If you convince your neighbors they need huge hard drives for
cable modem service, just think of all the extra disk space
you will have available. :-)

I don't see why it wouldn't work. We've grabbed a DHCP license
with a win95 box and then transferred the ip address to a 5.0.5
machine with the same MAC address.

A friend tested the DHCP hijacking bug that was found about 2 weeks
ago on his Road Runner connection. Totally screwed things up.
Be aware that Win98 will set it's address to 165.x.x.x (don't
remember the full string) if it doesn't get response from
a DHCP server in time.

UnixWare 7.1 (which is an OS from SCO) does come with a DHCP client.

Maybe you can switch to UnixWare7 (the way to go) and use it.

Tony,

For cable modem access, I decided on an ethernet-to-ethernet router/firewall
such as the Netopia R9100 (WebRamp makes a similar product). I had two
motivations for doing this:

1 When your trusty dusty cable guy comes to "install a network card in
your box", you are suddenly sharing your system with a rather large IP
segment (the netmask here is 25.255.248.0). Since I allowed the install on
a Win95 machine (so no damage would be done to my 'real' machines), I
checked out the network neighborhood and noticed many unsecured workstations
and various system and personal "handles" one might expect to find in a
hacker group. Having them on the same segment is just too close to home.

2 The firewall features are minimal, but the box acts as a DHCP client
to the outside world, performs network address translation (NAT) to hide my
machine from the outside world, and so-far has not interfered with my
Internet access from any of the clients I have tried. You could perform
this function with your LINUX box, but at a considerable cost in your time.

The MS DHCP feature from hell is described at:
http://support.microsoft.com/support/kb/articles/q220/8/74.asp


I once found a Perl script on CPAN for doing DHCP. However, when I
went back to look for it later (and forgetting to bookmark it), I
couldn't find it. I'll try again.

Our Operation uses a Multitech Proxy Server. it is a Dual Ethernet Proxyserver
model MTPSR1-120. works great. The set up was very easy. Give it a look
into...we use an Dsl line but it works with cable also......WWW.Multitech.com

Or should I say kevinjam...@yahoo.com ?

Go ahead an turf your SCO box. You already are a Windows diehard
with that NT4 dual 350 workstation you use to crunch out those
seti work units.... You know, if you ran Uw710, as the man Roberto
suggested, you could be getting 9 hr averages instead of 12 hrs 21 min
per work unit (and dhcp too :)

Good luck with windows 2000 !
