I think you're on the right track, but I'm not sure you'll ever be able
to get 100% of the functionality you want without hacking the kernel.
ipchains, for example, can only use the interface to figure out how to
handle a packet, not how to route it. If you wanted to hack the kernel,
though, you could use the "mark" option to ipchains to set up special
handling for packets that match certain rules.
You can do a few things along this line with DNS, however. First, you
can ask your DNS provider to set up your site's MX record to point to
the "fast" interface, so it always receives mail. Then set up your
routing table so that packets to your outbound mail host always go
through the slow host.
You probably won't be able to -- for example -- send an HTTP request out
on the slow interface and then receive the answer on the fast
interface. Such a thing would require custom software somewhere beyond
your machine.

Your ISP might set up an SMTP host you can use. If so, bounce mail
through it. That way outbound email goes out on a given interface, but
appears to be coming from the ISP's SMTP host (though with your site's
headers on it). Inbound email can then come from the other interface.

Try iptraf. It doesn't keep stats, but at any one point you can see
what kind of connections are going on, including byte counts on each
connection. If "users" and "client computers" are the same thing (i.e.
one user per IP address) this may well be sufficient.
You might also look into the IP accounting stuff. You may have to build
some tools on top of it to aggregate the resulting data into something
meaningful.

I recently installed Seyon 2.14. I thought setting it up would be a
no-brainer, and it was (very good man page), until I encountered my first
busy signal.The program hung, with the message BUSY:sleeping(10s). It
never reidalled, and I couldn't do anything in the program. Had to kill
the process.
Anybody else had this problem? Any ideas for what it is/how to fix
it? I've tried some different dialTimeOuts and dialDelays in my
.Xresources. No effect. Is there a command line flag I haven't read
about? Something that I ought to put in the startup file?
Thanks in advance for any help.

Wow... usually this is done the other way around! But to answer your
question, you are on the correct path. You will need to use a proxy server
like WinGate on the Windows98 machine. If you are not going to use this
setup for very long, you may be able to use the 30 day trial for WinGate. I
used it about a year ago for 2 weeks as a backup internet gateway. If the
setup is going to be permanent, switch your config and have Linux be the
gateway... the Linux masqing software is priced right :) and far more
powerful than any freebie Windows proxy application that I've ever come
across. If you haven't checked yet, www.winfiles.com has an excellent
listing of shareware and trial software (at last check, included WinGate).
BTW: Remeber to setup a default route (gateway) on the Linux box once your
Windows proxy is running. This tells the machine what IP address it should
use to get to the outside world (internet). If you do not know how to do
this, type "man route" to get a manual.
Good Luck!

In newer kernels (2.0.33+ or so), IP forwarding isn't enabled by
default. Try adding this:
echo 1 > /proc/sys/net/ipv4/ip_forward
to whatever "turn on masquerading" scripts you have. Before you do it,
though, try:
cat /proc/sys/net/ipv4/ip_forward
If it says "1", my solution won't help you. If it says "0", then it was
indeed disabled, as I'm guessing.

A Dejanews search pulls up some old posts explaining the sensitivity

tuning the system to prevent this happening. How would I go about
tuning the floppy subsystem to make it stop hogging the bus?
Note the "Couldn't get a free page" errors as well. When this happened
eth0 went dead. I was able to restore operation through ifconfig
down/up and restoring the routes, but the interface was stuck in
promiscuous mode until I rebooted.
Thanks.

Subject: Bandwidth friendly mail notifier ?
Date: Sun, 7 Feb 1999 18:20:00 +0800
Hi.
I'm developing an application for mobile radio packet terminals to use the
internet, especially email. But, because of bandwidth and power saving
limitations, I'd like to be able to have a program which notifies me when
new mail has been received in my mailbox.
On the server side, I'm running linux, and on the mobile terminal side, I'm
running windows mainly. What I'd like is to be able to have a notifier
sitting minimised on the desktop, and when the linux server receives mail,
it notifies the notifier on the appropriate windows desktop.
This would alleviate the need for the windows machine to clog the network
with packets every 10 minutes just to check if there's any mail.
I've seen a couple of things like this which work when there is an MS
exchange server, and plenty of notification clients which continually poll a
POP server, but neither of these is appropriate (unless there's an exchange
clone for linux).
Ideally, I'd like the windows notifier client to simply send a request to a
certain port on the server, including the name of the account, the password
and the return IP address when the client is booted up, and similarly a
packet when it is shut down. Then, whenever the server receives new mail
for that account (this side could poll for mail like fetchmail, or receive
an event like sendmail), it sends a packet to the appropriate windows
notifier client, informing it of the new mail (possibly including some extra
information, like the total number of messages outstanding, their size
etc.).
Does anyone know of such a beasty (well, really pair of beasties - the linux
server side and the windows (and maybe linux) client).
Does any or all of this exist already ?
Thanks.

The quick and dirty approach is to login as root and type the following
commands:
ifconfig eth0 192.168.1.1 broadcast 192.168.1.255 netmask 255.255.255.0
route add -net 192.168.1.0 dev eth0
This will connect your linux box to the network, and assign it an IP
address of 192.168.1.1.
Configure the win95 box similarly, but give it an IP address of
192.168.1.2 (can't remember how to do this, except I think it's under My
Computer somewhere) and reboot it (that's how you enable a new config
with win95).
Now you should be able to sit at the win95 box, start the telnet application
and connect to the Linux box's IP address.
To make the Linux box's IP address remain through a reboot, you'll have to
use the configuration tool that came with your distribution. If it's RedHat,
the tool is called netcfg; don't know for other distributions.
