The WINS server is keeping a list of all visible SMB-compatible machines
using the IP address as seen from the Linux (WINS) server. Your Win95
machine does not go through the masquerade to get to the WINS service, so
it is being registered as 10.0.100.X. Since your Linux machine is
masquerading all ports, the Win95 machine is then connecting to the smb
network as 10.0.0.203. Not only is it coming on an unadvertised address
(and therefore may be ignored for security reasons), but there is no way
for the smb machines to connect back to the Win95 machine because
masquerading is a one-way deal. When the smb machines try to send
information to the Win95 machine at 10.0.0.203 the Linux server happily
throws the packet away.
Turn off masquerading on the Samba ports so the Win95 machine can
communicate directly to the Windows network (using the Linux machine as a
router only).
Example:
ipchains -P forward DENY
ipchains -F forward
ipchains -A forward -b -p TCP -s 10.0.100.0/24 -d 10.0.0/24 137:139
ipchains -A forward -b -p UDP -s 10.0.100.0/24 -d 10.0.0/24 137:139
ipchains -A forward -j MASQ -p TCP -s 10.0.100.0/8 -d 0/0 -i eth0
ipchains -A forward -j MASQ -p UDP -s 10.0.100.0/8 -d 0/0 -i eth0

Mark,
Bind now uses named.conf which has a totally new syntax from named.boot. I can't
remember
the location of the "converter" utility on RH5.2, but I think it is in the
/usr/doc/bind
directory. Look for a filename of 'named-bootconf.pl'
This is a perl script that will take your existing named.boot file (as input) and
convert
it to the new format required for named.conf. Worked great for me...

Well first off is it multi-homed??? next ne2000 compat isn't hard you
just have to have the correct irq's and i/o. If you are multi-homing
using two ne2000 compats, I'd suggest copying ne.o to ne1.o and assign
one module to each card i.e. etho gets ne.o and eth1 gets ne1.o.
If you need more help e-mail me

You need a packet driver for your nic and a package like NCSA telnet.
You could also use a package like bobcat to run lynx-in-dos and view

In the simplest terms, Linux does not restrict how many clients you have
masquerading behind the gateway IP address. Linux has firewall
services, too. Please look into Linux before buying Wingate. It could
save you several bucks. Plus Linux is 'free' or very inexpensive.
Linux is an ideal solution for your needs. Inexpensive and simple to
implement.
Also, look into the HOWTO's in the Linux Documentation Project:

Actually minicom can handle ppp, I used to use it before i found wvdial. I

So how have you set it up, and how do you keep BIND from
kicking off a connect when it does its periodic maintenance?
Are you running a caching-only nameserver, or a 'real' name-

I'm having the same problems hooking up to ATT's @Home. DHCPCD does not
appear to be working at all in mandrake 6.0. It fails to get the IP info
from the cable modem. All I should have to do is edit the
/etc/sysconfig/network-scripts/ifup and replace the $PUMP references with
dhcpcd -h <hostname> which I did. Of course, everything works just fine
under Windows 98. If you find an answer please send it to me.

I'd just like to add that yup - IP Masqerading works great, and is really
easy to set up too! But make sure you've got decent firewall rules -
especially with the combination of the 'always on' nature of DSL connections
and having a static IP address.

Ok, here's the situation. When my cable company finally releases cable
internet service I'm going to buy a BeadleNet SOHO 2000. What it does is
act as a firewall/hub, and masks 4 machines behind one IP. If you enable
DHCP and allow DHCP for WINS resolution it will allow up to four machines to
share files and the Internet connection. My question is how do I make my
Mandrake 6.0 machine do that. I think I remember how to tell it to use
DHCP, but I'm kind of lost on the DHCP for WINS resolution. It's easy on my
wife's Win 98 machine, it's just a checkbox. Any Ideas?
