I've not used pppconfig but the things required for CHAP authentication

You need a /etc/ppp/chap-secrets file, usually one with the single line
<username> * <password> *
works. Of course <username> and <password> are placeholders for the
real things.
You also need the pppd option "name <username>", /etc/ppp/options is one
place where it might be configured.

This is a callback LCP option (13) but I'm not sure about the 03 00 data
fields. Looks like the ISP asked for it but pppd is not built for it.
The ISP seems to have accepted the rejection without trouble so it
should not be a problem here.

I haven't heard of those cards lately. Check the HARDWARE-COMPATIBILITY
HOWTO to see if the card is listed. If your card is ne2000 compatible
then the appropriate drivers should work. If they don't then i'd suggest
you double-check your jumper configurations and possibly open to the idea
that your network card is toast... It doesn't take much for a network
card to go...

Subject: Masquerading and Performance
Date: Mon, 28 Dec 1998 15:11:03 -0500
Hello,
I have a question on performance of a Linux box used as the
gateway for my computers to get on the network. Also about using the
Linux server while its online
working hard.
The setup is all working and fairly fast. The setup is:
Laptop NT
server Linux8
98
Modem PPP0 <<--->> ISP
128.125.1.7
========================128.125.1.1===========(eth0)128.125.1.8
The modem card is a Rockwell something running X2 (no V90). My
connection
speed is usually around 31k to 56K.
When I use the two MS boxes the response is good. I monitor on
Linux8 with
tcpdump on PPP0 and eth0 and xosview and xsysinfo. The load and %cpu is
low along with mem usage and cache usage.
If I start an applicaiton such as Netscape my mem useage goes up
and cache
expands even more. This is probably normal. I have 64 meg of SDRAM on
a
200 mhz Cyrix board. It looks like I cannot do much apps work on the
server which
probably should not be done anyway BUT - I would still like to know if
there is any
tuning I can do to 1. Permit the server to run better when its used
solely as a server and 2. Allow me to use it lightly while its a server
and not affect its performance as
a server.
I should add that the net cards are 10mb's.
Grep'ing through the HOWTO's did not produce anything that seemed
worthwhile.
There must be some system parameters as opposed to IP specific
parameters that are
available. Any pointer to information would be appreciated. Also any
information on
shareware system monitoring tools would be helpfull.
Can anyone point me to the source for xosview or xsysinfo? Is there
a system
call simmilar structure to sysinfo in Linux that can be gotten from the
kernel?
Thanks

Hi,
I have a configuration question about having a server connected to a
Linux
machine using masquerading. The question is how to configure the NT
side of things.
I have tried several configurations add would like to know its possible
or any
documentation you may know that is available. I have not found anything
that addresses
this in the HOWTO and probably would not expect to as its on the NT
side. I'm hoping
to find someone who has set up something simmilar and can point me to
some doc.
Laptop Intel base Intel base
Roadrash Server Linux8
OS:98 OS:NT server OS:Linux RH
128.144.1.7<<hub>>128.144.1.1<>128 125.1.1<<hub>>128.125.1.8
PPP0
--->Modem----Dialup ISP
assigns
dynamic addr.
I could not get the above working. I took out the 128.144.1 card from
Server and
reconfigured Roadrash to 128.125.1.7. I setup the DNS on Server to
point to the ISP's
settings which were the same as in /etc/resolv.conf on Linux8. The
system looked like
Laptop Intel base
Intel base
Roadrash Server
Linux8
OS:98 OS:NT server
OS:Linux RH
128.125.1.7<<hub>>===128 125.1.1-----<<hub>>-----128.125.1.8
PPP0 --->Modem----Dialup
ISP assigns dynamic addr.
This all worked fine. Laptops DNS settings were also modifies line
Servers to
the same setting as in /etc/resolv.config.
Again the goal is to get the top configuration working but I'm confused
over how to
setup Server with two cards and have it be an independant server/router
with its
own DNS setting but still forward packets forward to Linux8.
Any information would be appreciated.
Thanks

Then why you are not using one from a long list of non-modal editors?
There are so many to choose from very simple ones, like xedit or pico,

Date: Mon, 28 Dec 1998 11:35:17 -0500
Read Josh Gentry's paper he published on 12/27 on this newsgroup. It was
invaluable in getting the basic dialup connection running.
Now, I'm trying to get PAP authorization running so that I don't have to
bring up a terminal window on my Win95 box just to login. I'd like my
dialin to work exactly like my other DUN connections...just point, click,
and away you go.
Something else I noticed...when I did a WHO as root (on the Linux box), the
command returned my root sessions but not my ttyS0 connection. In fact, WHO
just hung. Can anyone tell me how to make WHO work correctly?
Thanks,
Charles

That IP address isn't merely bogus (i.e. not assigned), it's impossible.
No octet of an IP address can be greater than 255, so an IP address can't
end in .456. He must have replaced the addresses in the log message.
Of course, if the "from" and "on" addresses are both the same, as in the
faked log message, and the "on" address is his own machine, then either the
source address is forged (as most SYN floods are) or something is looping
on his own machine.

Routing, definitely. Neither card is at fault, since both cause the
activity led on the other to blink, so the physical layer is fine. Your
routes for _both_ machines must be properly configured. My guess is that
you set one or both of the machines as a gateway. If this is the case
then one of your machines doesn't understand that it is physically on
the same network as the destination, and rather than address the packet
to the host directly it tries to "route" the packet through the "gateway"
(the other host). Depending on which OS the host runs, the packet either
gets lost or bounces off to another gateway. OTOH, if your linux box
is supposed to be a real gateway for the NT box, perhaps via a modem,
then still the NT box needs _two_ routes: one to the local network and
one to the default network (Internet) using the linux box as gateway.
Likewise your linux box needs two routes.
On the linux side, look in your /etc/rc.d/rc.inet1 (for Slackware, I assume
the other dists use similar) for the ADDRESS, NETMASK, NETWORK, BROADCAST,
and GATEWAY. Set these values correctly. Example: address="192.168.1.1",
netmask="255.255.255.0", network="192.168.1.0", broadcast="192.168.1.255",
gateway="". Or you can manually set it this way:
ifconfig eth0 down
ifconfig eth0 address 192.168.1.1 netmask 255.255.255.0 broadcast 192.168.1.255 up
route add -net 192.168.1.0 netmask 255.255.255.0 eth0
Then in the NT side, under CP->Network, set its ip address and netmask, and
make sure the gateway is empty.

I don't know whether you are simply trying to learn about the HTTP
protocol the hard way. If you are, there are some excellent resources
out there. For starters, check out the libwww-perl library home page:
'http://www.linpro.no/lwp/'
Boris
P.S. With libwww you don't even need to know about HTTP. I can also
point you to some books later (I don't have them close by and I don't
remember titles and authors right now) - just send me an e-mail

>How do i setup my internet connection to work under linux?
What kind of connection do you want to establish? An analog modem
connection? A cable modem connection? A satellite link? What?
I will make the following assumptions to save time:
1. You want to establish a 33.6 or 56K modem connection to your ISP.
2. You want to control when the line is active and when it is not.
3. You do not want to automate the connection. You will run the connect
and disconnect my hand or cron job.
4. You will connect via the PPP protocol instead of SLIP or CSLIP.
The first thing to do is recompile your kernel with PPP support turned
on. Once that's done, you will need to adjust your your serial line
boot scripts to initialize the serial port:
cd /dev
SETSERIAL="/bin/setserial -b"
PORTS=`echo cua? cua??`
AUTO_IRQ=auto_irq
${SETSERIAL} -bg ${PORTS}
Make sure your modem is installed and that you can run minicom to test
your connection to the ISP. Make sure all the protocol bugs are worked
out, minus the PPP protocol. Minicom can also show you how to initialize
the modem for use. You can use that information in the chat script below.
One the modem installation, setup, and testing is complete, you will need
to use the following scripts. Read them over carefully and let me know
if you have any questions.
ppp-on is used to start a connection.
ppp-on-dialer is used to actually talk to the modem and get the connection
established.
ppp-off is used to terminate a connection.
apppd is a script that will keep your connection active 24x7.
Enjoy!

A few years ago your response would have been correct; thankfully (for
those of us who are assigned IP addresses dynamically), it isn't true
any more.
There are several places that offer dynamic DNS, i.e. allow you to
keep a fixed hostname even with dynamically assigned IP addresses.
With dynamic DNS it is possible to run an smtp server on your Linux
PC at home.
Monolith internet services (ml.org) used to offer a free dynamic DNS
service -- unfortunately they don't any more. There are several other
places that offer dynamic DNS service for about $20 a year. I use one of
them -- www.tzo.com, and am pleased with their service.
