Your dhcp server will look at the MAC address of your nic card every so
often and update the ip and hopefuly assign you the same one everytime (no
promises). But you also need your ISP's DNS to add your www.yourname.come
to their database (probably for a charge) so the rest of the world cn find
you. See if your ISP will assign you 2 static IP's, one for the primary PC
and one for the secondary. Then you have to tell Internic which one is
primary ip and which is secondary ip. The trick is getting your ISP to
assign you static ip's. Can they (yes), will they (maybe). Hope this helps
and hope it is accurate.

I am trying to hook up an ASDL line to my Linux box. I have two ethernet
cards. The first is for the LAN and is 10.0.0.10/255.0.0.0.
The eth1 card for the Cisco router is 10.0.0.99. Should it be on a different
subnet?
I am connecting to USWest and have a dynamic IP.

Subject: Linux Firewalling/Multiple Ethernet Question
Date: Mon, 21 Jun 1999 14:09:50 -0500
I am interested in setting up a firewall using an existing Linux
server. I will have a 512K frame relay link connected to a router that
will then connect into eth0 on the Linux box, and eth1 will connect to
the internal network. The internal network will be running a class C
address space, so I need to know how I can go about doing this with
multiple ethernet cards. Do I need to further break up the address
range so that each network card will have a different subnet? I
understand that there may be some issues with the same subnet on 2
cards.
Thanks,
Chris Zimmerman

A recent tcl/tk program has been developed for unix systems that
acts much like Microsoft's Network Neighborhood. Its useful for
browsing college dorm networks (among other things). If you've
used Network Neiborhood in Windows, you know what it does.
Its been tested successfully on Linux and Ultrix, but will run on
any unix with samba and tcl/tk. It can be found at:

If you're using an external ADSL modem, you can make your linux box to
connect to your ISP.
However, with an internal modem, it's negative.
You need a ADSL NIC driver for linux.
But, I never heard such a driver was made.
For more information, send a mail to me.

Hi,
Does anyone know whether it's possible to print to a printer
attached to a Windows 95 (Sorry!) machine from Linux. The reason I want
to do this is because the printer itself is one of those "Windows"
printers. I figured if I have a sort of print server (486) I could use
it from Linux. If anyone know of any sites which would tell me how to do
this that would be great.
Thanks in advance.

the IP address I'm pinging is that of the ppp server, is it posible that

never receives anything back. I tried to get tcpdump to listen to the

Subject: vpn and linux
Date: Mon, 21 Jun 1999 18:22:35 GMT
Hi,
i need some help on my corporate network design.
i'm planning to deplay a corporate network over the internet.
my company has two sites, eg. site a and site b.
i'm planning to use poptop on linux.
i'm thinking of the following configuration:
site a: internal adress 192.168.1.X
external adress 1.2.3.4 (from my isp at site a)
site b: internal adress 192.168.2.X
external adress 5.6.7.8 (from my isp at site b)
each site has this configuration:
internal net -> firewall -> external net -> router -> internet
on the internal net we use nt workstation 4.0.
the firewall is planned to be linux. on the external
net is our web and mail server. machines from the internal
net have to access the www and mail-server through the firewall.
the firewall is configured to be ip packet filtering.
now my questions:
1. is it possible to install the firewall (ipfwadm) and the pptp
server/client (poptop) on the same machine ?
2. how is the corporate network traffic filtered out from site a to
site b (something like route 192.168.2.X -> 5.6.7.8) ?
3. is it possible with any pptp solution on linux to provide
connectivity for some windows nt/98/95 clients for remote access ?
4. has anybody performance considerations for this configuration. what
types of boxes (486,586,PIII-550,XEON,ALPHA....) do i need for the pptp-
encryption ?
5. am i on the right way or should i rather use two microsoft nt-
servers with pptp or some
cisco or other third party solution ?
these are enough questions for today.
thank you very much for any help.
kw.

Thanks for the reply. Your explanation of the 'tar' syntax cleared up the
problem.
As far as IP-Masquerading is concerned, I have implemented all of the
steps listed in the HOWTO and
other posts but I can still not get beyond he point I described in my
<long> call for help. I am not sure whether I need 'named'
to be configured or whether to use ipfwadm to achieve my end result which
is to be able to access the internet from my W95 box
and / or my Linux box at the same time.
