The initial "-j" there is unnecessary .. it should be
/sbin/ipchains -P forward DENY
It might also be worth putting this first -
/sbin/ipchains --flush input
/sbin/ipchains --flush output
/sbin/ipchains --flush forward
to remove any old rules.

That looks almost there, except you are not specifying the machines you
want to masquerade for. I have somthing like
/sbin/ipchains -A forward -j MASQ -s $LOCALNET -i $EXTERNAL_INTERFACE
Where localnet is the machines I want to masquerade for (IE
192.168.1.0/255.255.255.0) and EXTERNAL_INTERFACE is ppp0.
<snip>
The above works on my machine, so if it doesn't work on yours then the
problem is not with your ipchains syntax.

Wrong. The machine should have the ip's 192.168.x.y where x is IDENTICAL for
BOTH machines, and y is uniqe for both machines, you can not have a y value
of 0 or 255 (127 and 128 should be avoided too)

You want "proxyarp" on the server and "defaultroute" on the client.

BTW: Especially when using proxarp you should make the IP address of
the server's PPP interface the _same_ as its ethernet interface[1]. This
is the default pppd behaviour. It won't cause big problems if you
don't but you'll see a few minor odd effects.
[1] Many people will tell you that this is impossible/wrong. These
people are mistaken. Ignore them.

Subject: passing data from ttyS1 to ttyS0 and vice versa
Date: 14 Apr 1999 16:01:38 +0200
Hi folks,
I'm trying to use my modem from two computers with totally different
operating systems (Linux and AmigaOS to be precise). My Modem is
connected to /dev/ttyS1 and works fine under Linux. The Amiga is
connected via nullmodem cable to /dev/ttyS0. The thing I intend to do
is use the modemline for Amiga applications, that have absolutely no
idea, what TCP/IP is. So IP-Masquerading or IP-forwarding will not
work for me, as long as there is no special tcpipserial.device for the
Amiga ;-) that provides a virtual serial port, that is in fact
accessed via TCP/IP.
Is there any application, that passes all data between the two serial
ports ttyS0 and ttyS1 in both directions so that the Amiga believes,
its connected to a real modem?
cat /dev/ttyS0 > /dev/ttyS1&
cat /dev/ttyS1 > /dev/ttyS0&
does not really work as both commands wait for a return until they
forward data.
The cableconnection works fine and a real TCP/IP-connection between
both computers works flawlessly.
Any Ideas? Can't be that difficult.
(again: no IP-forwarding or IP-Masquerading is wanted)

Start with the howto's on SAMBA
KH on installing software is required (rpm)
samba itself is fairly easy to use and configure.
The required howto is the SMB-HOWTO.

In addition to Curt's post, I will add that you need to make the ppp device the
default route. When you are connected to the isp, issue a route command and see
if ppp0 is the default route. If not, you can add it this way:
route add default ppp0
If a default route beside ppp0 is set, then you must remove it before setting
the new route. A default route can be removed like this: route delete default
Your windows machines need to have a gateway set as well. The gateway address
should be the same as the _internal_ address of your Linux box. The Linux
internal address should be bound to your network card, normally eth0.
Of course, don't forget to make sure that all machines share the same network
number and netmask.

Ppp-on is a script which dials and connects for you. You don't use it
as an option to pppd. You type `ppp-on' at the prompt or
`/etc/ppp/ppp-on' at the prompt. Then it sets some environmental
variables and uses ppp-on-dialer to actually handle the modem. When
the dialing part is complete, ppp-on then runs pppd.

In addition, if you want to use only one ethernet card in the linux box
connected to the internet, you need to set up IP Aliassing (i.e. a kernel
compiled with this option and an ifconfig for eth0:0 at system
initialisation).
the net-3-howto is the right source together with the ip-masquerading mini
howto.

Hi,
i have set up an Network with one Linux box and Samba and one Linux box as
router for
three subnetworks (Win95/98/NT). Samba works fine. The problem is that it
isn�t possible to log on from
a NT-machine (192.168.0.x) to the Samba server (192.168.1.x). To log on from
Win95-machine that is in the same subnetwork like the Samba-server to the
NT-server in the other subnetwork is no problem. I can ping each box from
each other. I have edited the etc/hosts on the router too.
Anybody knows how to set up an simple DNS on the router?

Subject: mgetty: modem comm loop - locks up my system
Date: 14 Apr 1999 18:35:02 GMT
I have mgetty installed on my Debian/Sparc system. I have a remote
computer scheduled to call into the system every hour. Most of the time,
things work fine. But sometimes a call comes in and -- somewhere in the
course of connection -- mgetty locks up the system. Actually, it appears
that mgetty is playing a trick on my modem... Both the send and receive
lights glow on the modem, as if there is a send / receive loop going on.
The computer completely freezes, and I can't even telnet in. If I cut
the modem off, then on... the computer recovers.
I can't offer many clues: all I know is that mgetty isn't respawning...
and the log file doesn't show anything. On one occasion it said 'setting
ICRNL ONLCR' then restarted an hour later only to find the CD signal
active and was unable to init or force-init. On another occassion, my
remote computer dialed in / logged in, and was shown in the wtmp / utmp
listing until the computer's power was killed 5 hours later. In other
words, the logs don't help.
The log does mention:
cannot turn off soft carrier: Invalid argument
I think it's trying to lower the DTR, but I'm not sure.
Any help will be greatly appreciated. -Zach

Two days ago I switched my sendmail to smtp (uucp before). And i got
the same "strange" message, but mail from hosts which "produce" such
errormessages don't reach me or my server...
So what should I write to the postmaster of such mailservers?
Should they reconfigure their mailer-timeouts?
Or must I do an upgrade of my leased-line (128K)?
best regards,
Juergen

My understanding of IP Masquerading is limited. It's exciting to hear that
it takes so little time to set up, but I rather move into that at a later
stage. Right now, I need to know that my NT boxes can see the Internet via
the Linux box and they are not.

No, they don't have real Inet addresses (it's a B network with non-Internet
addresses: 172.16.2.1 .2 and .3).

Really? What happens if they configure icq to "use firewall" and set the
range to "6000-6020" or something? blocking 4000 only (as i have understood
it) blocks the ability to register NEW accounts? Or am i misstaken?
