Define local traffic. If local traffic means `traffic to and from my
masquerading box' then you CAN'T masquerade it, as it doesn't go
through the forward chain.
If local traffic means `traffic which doesn't go out eth0', then that
does it.

You mean $EXTMACHIP, not $EXTMACHINEIP. You had it right in your last
post, so I don't know where you got the above...
$EXTMACHIP should work if that is your real external IP....

FYI:
1) You means /proc/net/ip_fwchains?
2) You can simply move /sbin/ipfwadm to /sbin/ipfwadm.real, and
ipfwadm-wrapper will do this for you.

Think it isn�t that simple as you�d like it to be...
Here�s what I�d do: Create two crontab files, say /etc/crontab.1 and
/etc/crontab.2. The first one is with the mgetty, the second one without
it.
I�d then copy the crontab.1 to crontab at 5pm and crontab.2 to crontab at
8am (or the other way around) and then kill -HUP 1, which will refresh
init. You don�t need to reboot then.
That�s the quick and dirty way. A nicer way would perhaps to write some
kind of wrapper to mgetty, or maybe have run mgetty the whole day but
disable the serial port (with setserial) or disable the modem (something
like sending "ATS0=0" and "ATS0=1" to /dev/ttyS0 using cu or minicom -
but then again mgetty probably blocks the tty and you can�t do that).
Anyway, hope this helps.

You can probably do it with tcpdump. No need to write any software then.

Hmmm.. It should work. (or, rather, not work. 8-) I take it that
telnet is set up to go through the tcp wrappers? That is, that the line
in /etc/inetd.conf looks like
telnet stream tcp nowait nobody /blah/blah/tcpd in.telnetd
and not
blah .. blah blah.. /blah/blah/in.telnetd in.telnetd
?
It may also be a function of how the tcp wrappers were compiled and what
version they are, though that's just wild guessing..
Not that it would be much help, but does it still work if you have
in_telnetd_3.1 : ALL EXCEPT noses.org
?

That's nonsensical, as the linux box itself is 192.168.10.2

Yup, because the -net route no longer exists. You will always need at
least one route saying which network flows across eth0, like
route add -net 192.168.10.0
along with the other stuff.
<snip older stuff>
So to recap, on the linux box you basically need.
ifconfig dummy0 down
ifconfig eth0 down
[just to remove everything]
ifconfig eth0 192.168.10.2 netmask 255.255.255.0 broadcast
192.168.10.255 up
^^^^^ That statement needs to be just one line, in case your newsreader
wraps it to two.
route add -net 192.168.10.0
Then that should be set up.

Hi Mike
At the moment i'm using Sygate as a proxy which I found a lot easier than
Wingate, but what you need to do is set up an ip address in the default gateway
setting. I'm not sure the easiest way to do this in SuSe as i'm used to
RedHat. But the steps you want to take are to look at your network settings in
suse and find an option for setting a gateway, then what you want to do is put
in the ip address that the win98 network card is set too. Also I think there
should be an option that will ask if this gateway allows IPv4 forwarding, you
would want to check this to allow wingate to forward the ip packets. As for
setting up wingate i'm not sure if you will come accross any problems, but you
may have to set up certain services that will allow you to use mail and
newsgroups. If you are able to switch to Sygate (www.sygate.com) I would
recomend it as there is nothing you have to do to get all the services, it is
just a matter of starting the service and it basicaly routes everything as if
you had a direct conection from your linux box.
Sorry I can't give you more detailed instructions but I have no idea about the
SuSe configuration, but i'm sure that it will have something within the network
settings and if you have managed to set up the nic then it's just a matter of
pointing it to the win98 machine by setting it up as a gateway machine. Hope
you get things to work out
Kevin.

You should say which Linux distibution you are using!!!
I am using RedHat 5.2 and I've had the same kind of problem.
If the modem doesn't respond and your com-port (cua#) is set correctly?
Then it's sounds like your irq# is incorectly set in Linux.
First check your Irq# setting in Windows (Hope you know how)
Then in linux (I am assuming you are using RedHat 5.2) check The "rc.local"
File-settings (You must be "root")
First read the file : "less /etc/rc.d/rc.local"
Or
Use the command "setserial -a /dev/ttyS2" (or /dev/cua2)
If the irq# is not the same as in windows then you will have to change to
the same as the one in windows. (You can also find your modem's irq setting
in the modem's manual)
Editing the "rc.local" file in emacs is quite easy. you can put the full
"setserial command" in your "rc.local" file or just modify the irq#
If you can connect to your Isp but cant connect to the web the probobly
your DNS is incorect which you can get from your ISP.
Hope it works

guys, since i did exactly that today i thought i would jump in.

my modem was working for a long time (in my RH 5.1), but then i
configured my soound card, SB 64, and it screwed up my modem,
because when configuring it sndconf (pnpdump is the same thing but
doesn't create a file as i belive) created a NEW /etc/isapnp.conf
and as you noticed it doesn't uncomment there the right lines by
default. so check where you modem should be with for exampl
setserial /dev/ttyS1,2,3,4 then go to that /etc/isapnp.conf file,
uncomment the right lines and run isapnp with this file, and then i
needed to reboot.

Subject: Re: US Robotics 56k modem
Date: Mon, 10 May 1999 00:12:00 -0400
guys, since i did exactly that today i thought i would jump in.
namely i did configure exact same model of the modem (a 3Com US
Robotics 56K) and i did have to deal with isapnp business for the
last day or two.
my modem was working for a long time (in my RH 5.1), but then i
configured my soound card, SB 64, and it screwed up my modem,
because when configuring it sndconf (pnpdump is the same thing but
doesn't create a file as i belive) created a NEW /etc/isapnp.conf
and as you noticed it doesn't uncomment there the right lines by
default. so check where you modem should be with for exampl
setserial /dev/ttyS1,2,3,4 then go to that /etc/isapnp.conf file,
uncomment the right lines and run isapnp with this file, and then i
needed to reboot.
here is my newborn uncommented (and without other stuff that i don't
need)
isapnp.conf:
(READPORT 0x0203)
(ISOLATE)
(IDENTIFY *)
# Card 1: (serial identifier 02 14 12 91 dd e4 00 8c 0e)
# CTL00e4 Serial No 336761309 [checksum 02]
# Version 1.0, Vendor version 1.0
# ANSI string -->Creative SB AWE64 PnP<--
# Vendor defined tag: 73 02 45 20
#
# Logical device id CTL0045
(CONFIGURE CTL00e4/336761309 (LD 0
(INT 0 (IRQ 5 (MODE +E)))
(DMA 0 (CHANNEL 0))
(DMA 1 (CHANNEL 5))
(IO 0 (BASE 0x220))
(ACT Y)
))
# Card 2: (serial identifier 91 c3 93 8b a2 70 30 72 56)
# USR3070 Serial No -1013740638 [checksum 91]
# Version 1.0, Vendor version 0.0
# ANSI string -->U.S. Robotics 56K Voice INT<--
#
# Logical device id USR3070
(CONFIGURE USR3070/-1013740638 (LD 0
(IO 0 (BASE 0x02f8))
(INT 0 (IRQ 3 (MODE +E)))
(ACT Y)
))
# Returns all cards to the "Wait for Key" state
(WAITFORKEY)
note, my modem is at ttyS1.
good luck.
email me directly if you need more from me.
