It seems my cable company wants me to specify the IP address of a
particular dhcp server. As far as I can see, none of the dhcp-client
programs allow me to do this. Any suggestions?

Subject: Firewall to protect servers
Date: Tue, 20 Jul 1999 18:15:47 GMT
I'm going to have a DSL install at my home soon, and was wondering what
people had for recomendations on how to set up a firewall/router on a
Linux PC. I'll have a Cisco 675 ADSL bridge/router, and a 486/dx2-66
with 16Mb of ram and two NICs. What I was thinking of doing was perhaps
setting the Cisco to bridge only mode, and using the Linux PC to do all
of my routing. I'd like to have several Microsoft Windows machines
inside of the network, as well as two sun boxes. I'd like to have some
kind of security on my router either using packet filtering rules, or
NAT. I would also like to be able to have HTTPD/FTPD running on my sun
boxes, but still have them behind the router/firewall. Any suggestions
on a better way to do this, or pointers on what to read to get my RH6
machine configured properly to do this? Thanks,
Greg

Hi,
I've got an existing Windows NT 4.0 Enterprise Server which is running
the following Services: ,,Normal'' NFS File Sharings, DNS, PDC for a Domain,
POP3 and SMTP.
Now I've got the following questions:
- Which steps do I have to take to handle the Linux box as an Windows
PDC??
- How to create file sharings with Samba
- How to configure DNS Server
- Well, I've successfully configured POP3 and SMTP.

You could always write a Dial-Up Script (.SCP) file and load it on the Windows
machine -- see DUN / Properties / Scripting in the connectoid to your Linux
server.
I remember having to do this long ago to connect a Win95 PC to Compuserve (to
use non-Compuserve software).
Look for the dummy script called c:\program files\accessories\pppmenu.scp or any
other .scp files for clues.

Subject: getty dialin respawning
Running Slackware Linux kernel 2.0.29. I have a 33.6 external Zoom
modem connected to my serial port. I'm trying to run agetty in the
inittab
file. This is the command:
d1:12345:respawn:/sbin/agetty -mt60 38400,19200,9600,2400,1200 ttyS0
vt100
I've also tried ttyS1, cua0, and cua1 as the ports. They're all the
same. It starts up okay but respawns every 30 seconds or so. The time
isn't always the same. My syslog says this:
Jul 20 12:37:32 cedar login[135]: invalid password for `UNKNOWN' on
`ttyS0'
Jul 20 12:37:44 cedar last message repeated 4 times
Jul 20 12:37:44 cedar login[135]: REPEATED login failures on `ttyS0'
It looks like it's getting garbage from the modem or something. I had
this modem plugged into a serial port on another Linux machine that
died.
The settings on the modem haven't been changed. I'm out of ideas.
Somebody help!

Tell all the Windows boxes to use TCP/IP as their default protocol, and
then enable NetBios over TCP/IP.

The "howto" in your reply tells me that you are assuming I am in a Linux
environment! :-) Unfortunately, I am not (yet).
NetZero is a Windows-based software that has a .exe wrapper around a
proprietary Java application that basically tweaks Windows' dial-up
networking and connects to a PPP server. I get a fresh dynamic IP each
time.
Has anyone got Internet access sharing to work with NetZero?

Greg:
It looks like you grock Unix already so I would work on setting up and
configuring my Linux box and reading the HOWTOs on IP Masquerading and
IPchains.
RH6 does support a port forwarding mechanism that will allow forwarding all
port 80 requests from the outside of the firewall to the inside of the
firewall. While port forwarding can certainly make one httpd machine
accessible on the other side of the firewall, I don't know if it's possible
to make two masqueraded machines accessible using this mechanism. You may
have to get tricky and send all http requests to one Sun machine and use
Apache's virtual hosting mechanism + NFS to imitate the second web site that
exists on the second Sun. I've never tried it but just maybe Apache would
let you do this.

Subject: Inet access as normal user
Date: Tue, 20 Jul 1999 16:38:06 +0200
Hi everyone,
I have the following problem:
I configured my Linux box (RedHat 5.2, kernel 2.2.9) for internet access
using RedHat's netcfg. Everything works fine, but only as long as I am
root! I can establish a connection as a normal user with "/sbin/ifup
ppp0", but Lynx, for instance, keeps saying "Alert!: Unable to connect
to remote host" when I try to go to a non-local address. When I try as
root, it works just fine.
This problem could, of course, be a result of wrong permission settings,
but I couldn't find anything. I would be very grateful if someone out
there sent me some hints.
Regards,
SW
P.S.: Do I have to be on runlevel 3 for internet access?

Date: Tue, 20 Jul 1999 19:46:17 GMT
I don't know what the purpose of the packet is. I happened to notice it
after installing a Win98 system on my LAN. The IP address was an oddball
and it caught my eye. I would hazard a _guess_ that it is for some sort of
PointCast-like service that M$ wants to setup sometime down the road. The
ports are very strange indeed. Why the bit bucket? Sorry, I can't answer
that. I did however block all multicast without any complaints or
complications. YMMV.
We use ipfwadm. Here's the relevant lines:
# Nothing should come from multicast/anycast/broadcast addresses.
$cmd -F -a deny -o -S 224.0.0.0/3 -D protected/16
# $cmd = path to ipfwadm, protected = local net group

One difference between DHCP as implemented by MS and DHCP as implemented by
Linux is that MS DHCP sends the hostname along with the DHCP request. Linux
allows you to do this via the -h parameter on dhcpcd. My provider requires
the hostname since that's how they assign IP addresses (bogus!), but this
did the trick. Whether yours does or not, it might be worth a try. There
are also some other parms on dhcpcd you might look at.

It's possible, but it'd be cheaper, and easier to config with a real
hardware hub.
Unless you already have a bunch of network cards around, and still,
you're limited to how many slots you can use in your computer.
A small, 5-8 ports 10Mb hub can be had for about $45US.

You can set it up and use it, but there are certain problems, particularly
with very large packets (e.g. at or larger than the MTU) causing the system
