I would like to do the same thing. I have a linux box set up that
currently dials out via modem. I have my Win 98 setup to do the same.
My ethernet card is detected and works well however i can not seem to
figure out how to get to see my Win98 shares. I guess that I might be
able to make my linux box my Gateway yes? I have read the samba howto,
dns howto and net3 howto butt still am a little lost. Can anyone please

Date: Sat, 20 Feb 1999 23:50:56 +0000
Hi All!
I have a problem. I have successfully set up IP Masquerade
and diald under RH 5.2 on a K-6 2 platform with 128 MB ram.
It works great with Linux, Win 95, Win 98, and WinNT 4.0
Hosts. I cannout however, manage to get a PowerMac running
Mac OS 8.1 with open transport to actually connect.
When I open Navigator 4.04 on the Mac the diald/masquerading
machine dials and logs into my ISP okay. However, even
though I have repeatedly checked my search domain name and
dotted decimal address both on the Mac and in the Navigator
setup I cannot manage to surf or get navigator to see
outside.
It may be my lack of knowledge of settung up Navigator under
Mac. Any help/suggestions/etc. appreciated.
TIA

With the Motorola cable modem that @home uses, you need to do that
each time it's plugged into a differant network card. The cable modem
reads in the ethernet card's hardware address, which is individual to
each.

I advice you to get oss :

commersial application to get your sound card working in linux.
Make sure you get a version made for the type of kernel you are using.
A different way to get your sound card working is to compile the kernel

Btw- if you are using soundblaster you could try this :
modprobe sound

connect the two computers with a cable and setup tcp/ip of win98.
set wins server to ip of linux-server and give your win-host an ip.
you dont have to give the win98 machine a dns server, mine works well
without!
now edit /etc/smb.conf to your preferences and all shoud work well.

Help please. Linux newbie calling.
I have installed RedHat 5.2 on Intel PC with 3com 3c509 ethernet nic,
configured local IP, default gateway, nameservers etc. and dmesg seems
to report eth0 OK at 0x300, IRQ=10
However, when I try to ping either the local IP address or an address on
the local network, I get "ping: wrote nnn.nnn.nnn.nnn 64 chars, ret=-1"
"ping: sendto: Network is unreachable" (where nnn.nnn.nnn.nnn displays
my local IP addr).
I have told netcfg to activate eth0 at boot, but it does not. The Names,
Hosts, Interfaces, Routing settings all look OK.
I can activate eth0 manually through netcfg but when I restart it comes
up inactive.
Any ideas please?

Subject: ipfwadm docs ?
Date: Sat, 20 Feb 1999 19:50:17 -0500
hi all,
i was wondering if someone could direct me to some documentation on the uses
and arguments for ipfwadm. what i am trying to do is create a functional and
relatively secure firewall, but will allow hosts to be routed to internal
network hosts. ie allow www requests to be sent to the webserver, and ftp
requests to goto the ftp server .. etc...
i realize that this will compromise security, but i would like only certain
protocols to be forwarded to certain hosts.. ie no www requests be sent to
the ftp server and vice versa. and of course allow internal hosts free reign
to the internet.
-----------web server
firewall----|----------ftp server
-----------hosts
i would like to read into this a little more and see exactly what is
possible and what is not realistic, in regards to maintaing security.
could a 'double' firewall be possible ? maybe:
--------firewall--------hosts
firewall----|--------web server
---------ftp server
thx

If you mean you want a server that will handle Network Address Translation
and work with IRC then Linux will do so without any particular problems.
If you specifically want an application proxy to handle IRC I suggest you

Add the ttys that you want root to have login access to /etc/securetty.
If you install ssh on the linux box you can use a secure telnet client like
SecureCRT to communicate via telnet, just be sure to disable plain old telnet.
I'd recommend just using su - , though as opposed to loging in as root.
There's really no advantage to logging in directly as root -- you can do
everyhting with su -.

Apologies to the Linux community... (this isn't a very linux oriented

Let's use better terminology. Netbios (netbeui) is not routable; it's a
broadcast based protocol. Netbios OVER IP (i.e. when you only install
TCP/IP protocol on a 95/NT machine) is routable because IP is routable.
Both WINS and LMHOSTS are mappings between netbios names and IP addresses
(just like DNS provides a mapping between hostnames and IP addresses).
If you want a discussion about segment master browsers, domain master
browsers, and their limited use of WINS, see the MS TechNet articles I
list below.

So, the correct approach to having two domains that need to "see" each
other is to have each domain's WINS know about the other WINS. To do this
you need to create a (1B) static entry in Domain B's WINS for Domain A
(including PDC/BDC). To do this, you need to put it in an LMHOSTS file
and load the LMHOSTS file into WINS (static mapping dialog box). See the

No. You need either rinetd or ipportfw or ipautofw. rinetd runs as a
separate process while ipportfw and ipautofw configure the kernel proper.
Kernel-level packet filtering/routing will always be faster than rinetd.
In your original post you say that you are masquerading... this isn't
going to work very well since WINS doesn't tolerate address translation.
So how about this:
Protect both LANs with Linux boxes. Set up an ip tunnel (using ssh or ssl
for encryption) between the two linux boxes that will route the
unmasqueraded NT traffic. Then the WINS won't complain.
OR
Set up RAS and PPTP. Recompile the kernel on the linux box at your
location to support PPTP masquerade. Recompile the linux kernel at the
remote location to support PPTP inbound connections. I do this and it
works well for single machine access to a LAN over the Internet. Kind of
like a cheap VPN. NOTE: PPTP is not very secure.

Congratulations. You are the proud owner of a Windows-only
modem. The modem enumerator you mention is the windows only uart
simulator that prevents the non Linux world from being able to use
that hardware, as the manufacturers of such equipment have chosen only
to write those programs for windows, and probably they figure that the
rest of the world knows better, or at least knows that one would get
much better modem and computer performance with a hardware based
modem, though it would cost at least $2/unit more to build those, and
the windows crowd would be quite happy as long as they can get into an
AOL chatroom every now and then, and get their email, plus browse the
web...
You need a modem, and unless you need to move your machine
often, you would more than likely be happier with a goo external one.

What I meant to say was that the SOHOware Fast Ethernet kit is INCOMPATIBLE
with the Orckit ADSL (DSL) modem I have. The DSL modem only works at
10 Mbps, while the Ethernet hub in the kit only works at 100 Mbps. The NIC
cards in the kit are OK; they auto switch between 10 and 100. But you
need either a 10 Mbps or an 10/100 auto switching hub in order to talk to
the Orckit modem.
(This all presumes you are going to use the kit to set up a LAN, with the DSL
modem being the link to your ISP. If you are just going to use the NIC cards
from the kit and not the hub, it'll work OK with the Orckit modem.)
