What you want to do is called ip masquerading. I run 2.0.36, and
masquerading is controlled by ipfwadm, but the documentation on how
to do it is in the ip masquerading HOWTO.

Masquerading's very simple once you understand how to do it - standard
Linux! :)
You'll need another network card in addition to the card that's talking
to the adsl box. Then you use a couple of ipfwadm (with 2.0.36, the
2.2.x kernals use ip chains instead) commands to set up the rules
that masquerade packets from your local machine out to the net.
Short description: the NIC that talks to your local machines, and
the other machines on your LAN will belong to a local network,
commonly 192.168.1.x. You then in eesence tell ipfwadm "all
packets from 192.168.1.x should be rewritten to appear to have
originated from my dsl IP. When packets return, rewrite them so
they go to the right machine on my 192.168.1.x LAN".
Yes, this works when your dsl IP changes due to dhcp.
I'm running a small LAN here through a P200 I have (overkill, but
that's the box I have available). When you get it working, test
throughput going through the 386 masquerader to make sure it can
keep up with whatever connection speed you have. I've not tried
it on an old, slow box but I'd assume the normal 256kbs or 512kbs
type connections can be dealt with by the 386. If you got a
multi-mbs download connection then maybe not.
Testing will tell, though.

See the Documentation/CHANGES file that came with your source for 2.2.5.
All your other software at the correct version ??
If not that's probably your problem.
Just a beginners suggestion.
Others more experienced than me might tell us which is the likely culprit?

Subject: Redhat: installing via NFS problem
Date: Mon, 5 Apr 1999 12:48:25 -0500
I have three D-Link 530TX cards, which use the via-rhine driver.
I have also have two machines running Linux (RH 5.2), which
have CDROMS. Both of these machines have NFS working.
The third machine has only a small hard drive and no CDROM,
so I was wanting to install RH5.2 on this machine via NFS.
The problem is, though, that the via-rhine driver is not
on the list that I can pick from during the initial couple
install screens, after I select that I want to install via
NFS.
Is there some way that one can specify directly the driver
to use for the ethernet card, instead of being confined to
picking off of the list?
Thanks,

1. Check /etc/hosts.allow to see if box2's ip is allowed in.
2. Check /etc/hosts.deny to see if any ip is denied.
3. Check your firewall on box1 to see if you disabled telnet port 23
and ftp port 21.
4. Check /etc/services on box1 to see what ports telnet and ftp are
running on. Make sure you telnet to the right port.

I haven't done it, but I belive it is posible. You just have to tel samba

recived and so on. Read more about itin the smb.conf manpage. Especialy

Hi,
I am trying to connect to my ISP (for Internet access ofcourse). I am
using "minicom" . My modem (US Roboctic PCI 56K ) is connected to
device /dev/ttyS1 (com2).
My /etc/resolve.conf is as follows
nameserver 199.182.120.203
nameserver 199.182.120.202
They are the IP addresses of my DNS of the ISP. Its a PPP connection.
When i try to connect it kicks me out after 5 seconds and i get NO
CARRIER message. If i try to use the internet within those 5 seconds i
get " DNS entry not found" error in my netscape. I am using Redhat 5.2
and its really annonying as i have been trying this for couple of weeks
now and i have no idea whats going on. I would really appreciate if some
one could help me out of this.

And interesting case: there's a bug in my version of windows (the very
first commercial release of win95). Basically it amounts to this: you
can't use the "save password" button on dialup networking unless you
have microsoft networks installed (which I never use). This bug
persisted for almost 5 years, through many different versions. It may
even still be in windows 98, though I certainly haven't tried it -
that OS gives me the willies....
Certainly no bug like that has EVER persisted for 5 years in any open
source program, unless no one was using it at all. In that case, it
really doesn't matter...

You should look at http://www.sendmail.org/ and track down

You might try to delete the options. The NIC's should be recognised anyway.
Allso you should alter the alias-rows.
Like so:
alias eth0 3c59x
alias eth1 3c59x

The Celeron is not clocked locked, it's Multiplier locked. For example my
300a Celeron, 4.5 clock Multiplier, works flawlessly at 450 Mhz by going
from the default FSB of 66Mhz to a 100Mhz FSB.
Having built many systems around the new Celeron's, I can tell you 100%
that they are not clock locked but are Multiplier locked. Your milage may
vary with overclocking though.

I believe that initializing the modem with ATW2 will get rid of the problem
as well. It puts all the connect text on one line. Checking for the
speed won't work, because it may change from connect to connect.

Expect-send pairs at least allow one to trace the problem.
I don't want to debug or try to understand some convoluted script
someone else wrote to handle most (not even all) the possible
responses from a modem.

If that works for you, by all means, use it and be happy. Though I've
heard of many people who couldn't get a connection working with ezppp.
As well, scripts give you much more flexibility for those occasions
that warrant it. Personally, ezpp does me no good at all, because I
have linux installed on a 386, and I'm not about to run X on that! As
well, I'm using some other programs to operate the link - diald and
the like. With scripts, once you've done the work, you're set for all
these other programs too.
The best solutions I've found is to use pppconfig, since it has a
nifty little GUI (in ncurses, so you don't need X) but it works by
simply creating the scripts for you, so that you can then edit them to
your heart's content. I've never had a problem with it at all, and
have used the scripts that it produces for many other things, as well
as modifying them extensively when I wanted to try new things. I doubt
that you can do that with ezppp (though I've never used it, not
running X much)

I'm visiting right now and am using Deskjet Plus (also in options) and it
