Hello Everyone,

I have been trying to connect my linux box with my earthlink DSL.
Herebelow, I will try to explain each step I went through as elaborate
as possible so that you all can get clear picture of what I did. But
no luck. Following are the steps I did so far:
----------------------------------
1) After I typed "adsl-setup", it came as this: Welcome to the ADSL
setup...The following DSL config was found on your system:

Device: Name
ppp0 DSLppp0
ppp1 DSLppp1
ppp3 DSLppp3
ppp3 DSLppp3

notice: ppp3 was mentioned twice, It's not a typo. It exactly the way
it showed on the screen which is rather confusing to me.

Please enter the device if you want to config the present DSL
config(default ppp0) or enter 'n' if you want to create a new one:

I chose the default which is ppp0
------------------------------------------
2)Enter your login name :

here I entered only the name not after the @ part of my e-mail
address. For Example: I entered 'newoxygenlife' , NOT '@yahoo.com'.
I'm not sure if that would make any difference or not. As i went
through some newsgroups, different people commented totally different
ways on this issue. Couple of people suggested to enter
'newoxygenlife', while the rest suggested to enter the whole e-mail
address.Ovbiously it made me confused and I chose to enter the
'newoxygenlife' only.
--------------------------------------------
3)Enter the Ethernet interface connected to the ADSL modem. For
solaris it's likely to be something like /dev/hme0. For Linux, it will
be ethX, where 'X' is a number.(default eth0):

I went for default(eth0) here as well.
--------------------------------------------
4)Do you want the link to come up on demand, or stay up continuously?
For your link to stay up permanently, enter 'no'
NOTE: Demand activated links do not interact well with dynamic IP
addresses. You may have some problems with demand activated links.
Enter the demand value(default no):

I went for default here too. I don't have dynamic IP address(which is
extra $15). Therefore, I chose 'no' .
------------------------------------------
5)DNS
Please enter the IP address of your ISP's primary DNS server. If your
ISP claims that 'the server will provide dynamic DNS addresse', enter
'server' (all lower-case) here. if you just press enter, I will assume
you know what you are doing and not modify you DNS setup.
Enter the DNS information here:205.65.186.182 <- this is not the real
IP though, I used here only example.
Please enter the IP address ......for secondary
DNS:205.65.186.183<-again this is an example.

Please note that i tried both ways; typing 'server' and also typing
the DNS IP address(I had to call my ISP and get this IP address).
----------------------------------------------------
6)PASSWORD

Please enter your password:

I entered the password for my e-mail address.

Please re-enter your password:

Entered again.
-------------------------------------------------
7)USERCTRL
Please enter 'yes'(twho letters, lower case) if you want to allow
normal user to start or stop DSL connection:

I chose 'yes'
---------------------------------------------
8)Firewalling

0- no firewall
1- standalone
2- masquerade

I chose here 0 for my own reason. But I think it's changeable later
on.
----------------------------------------------
9)Start this connection at boot time

Do you want to start this conection at boot time? Please enter no or
yes:

I chose 'no'
---------------------------------------------------
10)Here is the summary of what I have entered:

Ethernet interface: eth0
User name : newoxygenlife
Activate on demand: No
Primary DNS : 205.65.186.182
Secondary DNS : 205.65.186.183
Firewalling : None
User control : yes

Accept this setting and adjust config(y/n)?

I pressed 'y'.
---------------------------------------------

Then I typed 'adsl-start' , after may be 15-20 seconds, here is the
output:


'/sbin/adsl-start: line 217: 5564 terminated $connect "$@"
>/dev/nu

11 2>&1


The above line has been very frustrating for last several days. I
checked my cable, switched different cable too, no luck so far. But
one thing I have noticed, in each session each time I try to start
ADSL, the number after 217: (which is here 5564) keeps going up.

I have been feeling very helpless on this issue. Any type of help
would be appreciated. thank you.

If you got this then the adsl-setup script is broken. There are various
adsl-setup scripts and such a script can vary according to the source
from which it is obtained.

Usually that would be correct.

What goes here depends on what name the ISP requires in order to connect.

That's okay provided the host is not attached to LAN and eth0 is used
for it.

So you get a permanent IP address for $15 *less* than if you got dynamic
IP addresses? That's the reverse of what I would expect. Anyway, no
may be okay, even though the "$15 less" as well as the NOTE seems very
peculiar.

Those should be available on the ISP's web site.

The adsl-setup and adsl-start scripts were written by an idiot unless you
hand-copied them and made numerous typos. In particular, the /dev/nu11 is
really bad! The $connect is a environmental variable, likely containing
the name of a dial-in script that doesn't work, for whatever reason.

That's the process ID and not a problem.

Find decent adsl-setup and adsl-start scripts.

Hello Clifford

First of all thank you for your kind response to my problem. At the
same time I would admit my stupidity on 'dynamic' and 'static' IP
addresses. Even though I know the difference, but I guess I blanked
out at that time. Yes, you are correct on what you had thought as
'static' address should be $15 more than the dynamic address. I'm
sorry for making it confusing. As you have guessed that I hand copied
the 'adsl-start' and 'adsl-setup' scripts, you are correct on that as
well. As far as typos, I would say English is not my first language
and I'm new with linux too(eagerly want to learn though). So, I
apologise for the confusion.

Besides, in places where you saw "......." inside my scripts, I just
omitted few words there thinking those would not be needed with the
context.
My problem I have been facing still remains. What should I do now? As
you indicated that '/dev/nu11' is really bad, what should I do on this
regard?

Thanks again for your kind help.

Zak

Well, if I'm not wrong, you're using RP-PPPoE. What I understand, you
don't even need that adsl-setup script though it worked pretty well
with my settings. I used it for quite long in 20 something pcs. I
won't say, the script idiotic cause, you see here ...

# Start the connection in the background unless we're debugging
if [ "$DEBUG" != "" ] ; then
$CONNECT "$@"
exit 0
fi

$CONNECT "$@" > /dev/null 2>&1 &
CONNECT_PID=$!

Okay, please dive into the file pppoe.conf and enter the required
information there. That will help you understanding the whole
mechanism and the trouble caused.

And here is the help file written by author himself. Please go
through.

1. Set up your Ethernet hardware
--------------------------------

First, make sure the Ethernet card you intend to use with the modem is
visible to the Linux kernel. Just how to do this is beyond the scope
of this document. However, if the card is the only Ethernet card in
the system, executing:

ifconfig eth0

should display something like this:

eth0 Link encap:Ethernet HWaddr 00:60:67:62:314

plust some more lines. Your HWaddr will be different. As long as you
see
the HWaddr line, your card should be working.

DO NOT assign an IP address to the Ethernet card. DO NOT configure
the
card to come up at boot time.

3. Edit pap-secrets
-------------------

Edit the "pap-secrets" file, inserting your proper user-ID and
password.
Install the file (or copy the relevant lines) to /etc/ppp/pap-secrets.
Your ISP may use CHAP authentication. In this case, add the line to
/etc/ppp/chap-secrets.

4. Edit /etc/ppp/pppoe.conf
-----------------------------

The file /etc/ppp/pppoe.conf contains configuration information for
the
ADSL connection. You need to edit the following items:

- Change ETH=eth1 to the correct Ethernet device for your modem.
- Change USER=(E-Mail Removed) to your proper ADSL user-ID.

Don't edit any of the other settings unless you're an expert.

5. Set up DNS
-------------

If you are using DNS servers supplied by your ISP, edit the file
/etc/resolv.conf to contain these lines:

nameserver ip_addr_of_first_dns_server
nameserver ip_addr_of_second_dns_server

For example:

nameserver 204.101.251.1
nameserver 204.101.251.2


6. Firewall your machine
------------------------

MAKE SURE YOU FIREWALL YOUR MACHINE. A sample firewall script is
given
in the shell script "firewall" To install the script:

a) Copy it to /etc/rc.d/init.d/firewall
b) Type: chkconfig firewall on
c) Start the firewall: sh /etc/rc.d/init.d/firewall start

(The above procedure works ONLY on Red Hat-like systems.)

You may want to tweak the script somewhat.

7. Bring up the connection at boot time
---------------------------------------

On a Red Hat system, the installation procedure should have installed
a script called /etc/rc.d/init.d/adsl. To bring up the connection
at boot time, just type this command as root:

chkconfig --add adsl

On non-Red-Hat systems, add this line to the end
of /etc/rc.d/rc.local:

/usr/sbin/adsl-start

8. Configure LAN Hosts
----------------------

If you have a LAN behind the firewall, you have to lower the TCP
maximum segment size from the normal 1460 to 1452 (or better, 1412.)
You have two options: Either set the MTU of all the interfaces on
other hosts on the LAN to 1452, or use the "-m 1412" option to pppoe.
The "-m" option for pppoe is far simpler and makes it easier to add
hosts to the LAN, but consumes some extra CPU time.

If you want to manually configure the LAN hosts, here's how:

In Linux, use: "ifconfig eth0 mtu 1452". For best results, put this
in an /etc/rc.d/rc.local script.

For Windows, machines, see http://lan.cns.ksu.edu/OS/WIN95/slip95.htm.
Set the MaxMTU to 1452.

------------------------

When everything fails, just have a peek into the actual PPPOE forum
here at http://www.voy.com/41165/

Have a great connectivity!

First you need to post exact copies of messages, not hand-copies.

I said /dev/nu11 is really bad because the number 1 is not the letter l.
But I understand that the visual distinction could be subtle for someone
whose native language is not English. I suspect that your hand-copy
changed CONNECT to the lower-case connect too. These are examples of
why you should not hand-copy.

The only ADSL scripts I have here are for rp-pppoe and I'm guessing
the one you have is not. Even given all the typos, differences appear
to exist. So it would help if you could provide a link (URL) for whatever
package the scripts come from. I personally would rather have a link
to avoid posting the entire script when it is big - as it seems to be.

The rp-pppoe script adsl-start runs the script adsl-connect to dial out
and connect to the ISP. That script runs yet another script, specified
on the adsl-start script, or /etc/ppp/pppoe.conf if there is none on
the command line, and then runs the command to actually start the PPPoE
session.

The problem appears to me to be a failure to dial-out, or to connect
after dial-out, but the single message from adsl-start about "line 217"
isn't enough for me to say why. You might check for an option to force
more verbose debugging messages.

> Thanks again for your kind help.


Actually I waited to see whether someone else would post who *knew* what
is causing the problem you have. I haven't ever done PPPoE ADSL, although
I do know PPP reasonably well and understand PPPoE enough to be dangerous.

One other thing. Please respond to the last reply posted and not your
original post. It's easier all the way around.

And later(?):

kill $CONNECT_PID > /dev/null 2>&1

# Clean up PIDFILE(s)
rm -f "$PIDFILE" "$PIDFILE.pppd" "$PIDFILE.pppoe" "$PIDFILE.start"

exit 1

I don't believe either of these can produce the message he posted.

Ghastly reasoning although the result should work: the MSS is not the
MTU, it is the MTU minus 40. For PPPoE you *should* be able to set the
MTU to 1492 for all LAN Ethernet interfaces so that the MSS of those
interfaces is 1452 and have things work. Now I don't know whether there
really are instances when the MSS actually must be 1412, for reasons
unknown to me, or whether it's *all* misinformation stemming from this.

Do all distributions have a /etc/rc.d/rc.local script? My Slackware
does but it's my impression that some distributions aren't structured
that way. The way "7. Bring up ..." above reads it looks like RH may
be one.

I'll try to do that, thanks. It might eventually clear the MTU/MSS
fog away.
