Hello,
You should read the LINUX-NT-mini-Howto that can be found in the Linux
Documentation Project. It will guide you through the installation.
You will also find everyhting concerning boot loader configuration.
URL : http://metalab.unc.edu/LDP and you can find several mirrors on the
net.

This is portforwarding.

Use portforwarding, or redir. `redir' is a program (the packets seem
to come from the redir box), portforwarded packets come from the
external box. ipchains' REDIRECT target is something again: it sends
packets to the ipchains box itself.
Hope that helps,

On one of my machines, I used the 2.0.36 tulip.c driver. I never tried
the Netgear-hacked version, because the first one I tried worked just
fine. On another machine, I never found any driver that would work:
not the 2.0.36 one, not the Netgear version, nor several that I tried
downloading from Donald Becker's web site.
As I mentioned earlier, the problem went with the system when the cards
were swapped between the two systems. These were two systems with
nearly identical hardware, and both with Debian 'slink'.
Subsequently (after getting a different ethernet card from SW Technology)
I found one probably innocuous difference in conf.modules: in the
non-functional machine, there was a line near the bottom:
alias eth0 tulip
I'd suggest to anyone struggling with this card that they try commenting
this line out. As a last, desperate attempt, of course. The machine
that continues to work nicely with the Netgear card does not have this
line, but that's probably a coincidence.

Making Rules Permanent
Your current firewall setup is stored in the kernel, and thus will
be lost on reboot. I recommend using the `ipchains-save' and
`ipchains-restore' scripts to make your rules permanent. To do this,
set up your rules, then run (as root):
# ipchains-save > /etc/ipchains.rules
#
Create a script like the following:
#! /bin/sh
# Script to control packet filtering.
# If no rules, do nothing.
[ -f /etc/ipchains.rules ] || exit 0
case "$1" in
start)
echo -n "Turning on packet filtering:"
/sbin/ipchains-restore < /etc/ipchains.rules || exit 1
echo 1 > /proc/sys/net/ipv4/ip_forward
echo "."
;;
stop)
echo -n "Turning off packet filtering:"
echo 0 > /proc/sys/net/ipv4/ip_forward
/sbin/ipchains -X
/sbin/ipchains -F
/sbin/ipchains -P input ACCEPT
/sbin/ipchains -P output ACCEPT
/sbin/ipchains -P forward ACCEPT
echo "."
;;
*)
echo "Usage: /etc/init.d/packetfilter {start|stop}"
exit 1
;;
esac
exit 0
Make sure this is run early in the bootup procedure. In my case
(Debian 2.1), I make a symbolic link called `S39packetfilter' in the
`/etc/rcS.d' directory (this will be run before S40network).

darn right it should be half! hubs don't do full duplex. mixing half and

you need a switch in order to do full duplex. switches are signifigantly
more expensive than a hub. i would just leave the cards at half duplex.
on a small network with just a few machines, you shouldn't notice a
signifigant difference.

the favorite seems to be the intel etherexpresspro 100 cards. the 3com 9xx
cards seem to vary in stability from machine to machine, and as for the
tulip cards, most people making 'em switched over to a cheapo clone a

hey,
I felt compelled to post this because it took me a while to find
the solution to this problem...
The netsurf GFC2206 10/100 PCI card with ONE rj45 connector has a
realtek RTL8139 chip on it - how did I
find this out? I called the 888 number on www.netsurfusa.com
I got this to work!!!! how? (btw, this may not the be best way to
do it, but I got it done! hura!!!
first - added this line in /etc/conf.modules
eth1 rtl8139
(because I have a eth0 already)
I also checked that the file /lib/modules/preferred/net/rtl8139.o exists
(this file is there from the stock installation of Redhat)
Second, I started x and ran the control-panel application
I then gave that deivce (eth1) an IP address and everything, then I set it
to be be active at bootime, and then hit "activate" then I tested to see
if it worked - using "ifconfig" on the command line, and it showed up!
next, I restarted, and it ALSO showed up.
I have tried for an hour with just adding the eth1 rtl8139 line in the
/etc/conf.modules WITHOUT going to the control panel. That did not work.
- it would say "failed" at startup. but now, it's FINE (after setting the
stuff in control-panel)
please letm eknow if anything of this was helpful to you, and if you need
any addtional help, I will try my best to help you...

You need to exchange the type of quotes, replace ' with " and
vice-versa. The way you've done it will cause trouble and could have
done so already since the '\d\c' is sent as dc (see the log) rather
than inserting a delay and surpressing the carriage return.
I'm not sure you actually got logged in since you are set up for PAP
authentication which would mask a login failure. It's unusual to have
both a login and PAP authentication - if the ISP requires PAP or CHAP
then it will almost never need a name/password login too. The effect
of doing both when only one is required could cause trouble.

Everything is normal until this point where you get a PAP AuthNak with a

hex dump is unusual. I've never seen this particular behavior in any
other post. I haven't used ppp-2.3.3 and can't say with certainty that
it's not a bug - the current version is ppp-2.3.7 and you should consider.

If none of the previous suggestions work the then try the pppd option

pppd option "kdebug 3" and post the PPP link negotiation log again.

You cannot do exactly this, because subnetting is limited. The division
between
subnet number and host number must be on a bit boundary; this means that the
number of hosts in each subnet must be a power of two. Thus, you can make
the subnet that has 4 IP addresses, using netmask 255.255.255.252, but you
cannot declare a second subnet that has all of the rest in it, since 12 is
not a power
of two.
However, you can get nearly what you want by decomposing this, declaring
two subnets and overlaying them on the same ethernet port. You would
declare one (for eth1) with netmask 255.255.255.252 to cover the remaining
4 addresses next to the 4 you are using for your router connection, and then
declare a second subnet (also on eth1) for the other 8. That netmask is
255.255.255.248.
The drawback to this (as you no doubt will find out) is that, since you
really
shouldn't use either host 0 or host `all-ones' on each subnet, you don't
really
have 16 IP addresses after all this, but rather 2+2+6 = 10 useful addresses.

> Step 1: The Set Up
> Set up a DHCP server and convert all of your client machines to get their
> IP address via DHCP. Set up the DHCP server so that all currently used
> IP's are excluded from the dynamically allocated range. You can do this
> step slowly, as time permits. Eventually, all of your client machines
> will have dynamically assigned addresses from your current address pool.
> Set the lease time to be *really* short, like 1 hour.
>
> Step 2: The Conversion
> Change the lease time to 1 minute. Within 1 hour, all of the client
> machines will have requested new ip addresses, each with expiry of one
> minute. Tell all users that there will be a 5 minute network disruption
> (i.e. save and close their work). Change the DHCP address range to the
> new range. Since the expiry is 1 minute, within one minute all the
> clients will have an address from the new range. Change the lease time to
> something reasonable, like 1 or 2 days. Done.
>
> This solution has the big benefit that at the end of the process you will
> have a DHCP managed ip address pool, which is, IMHO, much better than
> static addresses (if only so that you can change the nameserver, default
> route, etc. in only place only).
