[9fans] pppoe configuration

Hello, i've read
http://lists.cse.psu.edu/archives/9fans/2005-August/042646.html post
sequence, and i did try to configure pppoe in my plan9, but i cant.. here is
what i've typed:

glenda is in the sys group. (i'm logged as glenda)

% ip/pppoe -dp
# username, password... debuge info...
% echo refresh >/net/cs
% echo refresh >/net/dns
/net/dns : rc: can't open '/net/dns' mounted directory forbids creation
% net/dns -r # i typed that command to try to find dns for me
% echo refresh >/net/dns # now this command gives no output..
% 9fs source
srv: dial net"source"9fs: cs: can't translate address: dns: resource does
not exist
# even with these erros, i've tried a ping command
% ip/ping -n 1 www.google.com
ip/ping: coudn't dial icmp: www.google.com!1: cs: temporary problem: dns
failure

the lights of my moden are normal, as in my linux when i'm connected.

When i did the first command (ip/pppoe -dP), i 'cat /net/ndb' and there was
an ip adrres, ipgw address, dns address. i've tried to ping the ipgw too,
but it sends a package and doesnt recieve response.

at this point i rebooted the system and come to seach at 9fans, but i didnt
find anything...
anyone knows what can it be? Or where can i find something to help me to
configure pppoe.

Nearly right, I think you just need to run the dns server after
you logged into pppoe like this:

ip/pppoe -dp
# username, password... debuge info...
% echo refresh >/net/cs
% ndb/dns -r
% echo refresh >/net/dns
% ... etc

Pedro, recycle (reset) the router and give it another try.

Vester means your DSL modem, but I doubt that is the problem,
since you can send mail after rebooting into your other OS.
Also the modem/router responded to your PPP negotiation
and gave you an IP address, so it sounds like something is
working.

Could you write down the output of these commands?

  cat /net/ndb
  cat /net/iproute
  netstat -i

Thanks.

Apologies, I meant modem.

Anyhow, I once had a similiar problem. I found that my modem was the
culprit. My modem permitted only one computer access to the network.
When swapping out computers and attempting to connect via pppoe, I was
unable to connect. Only after resetting the modem was another computer
permitted to access the network.
Perhaps this is not your case, but I was hoping on an easy fix. Sorry
for any confusion.

The 3Com ISDN modem router I'm using restricts access to the Internet
to a list of workstations by IP address.  This is slightly more
complicated than the above, but it may also be relevant here.

i've made the changes in the ppp.c file and the results are:


i've changed, then connected (ip/pppoe -dP). this time i could ping my
gateway (lost  only 4 of 32), i've used the commands 'echo refresh >/net/cs'
and 'ndb/dns -r' fallowed by a 'echo refresh ./net/dns'.

when pinging www.google.com no output was given like:

% ip/ping -n 1 www.google.com
(nothing here)

i've tried '9fs sources' too,

term% 9fs sources
post ...

but nothing more that.

i've rebooted the computer and later i come to plan9 to try more.

this time every ping to my gateway was lost, '9fs sources' given a
'restricted address' error.

in the 2 tries the pppoe debug info give me lines like


SOME_NUMBER: ppp: putframe 0xHX_NUMBER nbytes
and sometimes
SOME_NUMBER: ppp: ppptimer

i didnt remember that msg before changing the code.

in the 2 times i've connected using the commands:

ip/pppoe -dP (in window 1)
'echo refresh >/net/cs', 'ndb/dns -r' and 'echo refresh >/net/dns' (in
window 2)

i'm using the 'ndb/dns -r' because if i dont use it, the 'echo ... /dns'
give me some error msg (i've told what is it in some msg before this one).

that's all.

if it can help, this is my /rc/bin/termrc file
http://rafb.net/p/taDMvM12.txt

i've added the line

ip/ipconfig loopback /dev/null 127.0.01

in my termrc file, but for an error i've added

ip/ipconfig loopback /dev/null 17.0.01

well, when i do 'ndb/dnsquery' then www.something.com it causes a '!dns
failure' message.
ip/ping 18.26.4.9 almost all requests wasn't lost  (only 7 of 32 lost)


later i modified the termrc to what it is (the first link) and the ping lost
all requests and when i do 'ndb/dnsquery' i got that /srv/dns doesnt exists.

i think that's all

Re: [9fans] pppoe configuration

[erik quanstrom]

i didn't see from your termrc where you are starting pppoe, nor
where you are configuring your network.  where are these being configured?

plan 9 doesn't need a loopback address (unless you're running venti).
what was the error message that you saw?

Re: [9fans] pppoe configuration

[Russ Cox]

Sorry, Pedro and I have been emailing offline and
the thread here has gotten a little garbled.

It looks like his ISP's ppp server doesn't like
the way Plan 9's ppp client talks to it.  In particular
the server won't respond to an empty configuration
request (meaning that the client has gotten all the
info it needs).  So we changed ppp to always include
the negotiated IP address so that the config request
is never empty.  That seems to have gotten past
the ppp problems.

I suggested inserting the loopback ipconfig into
/rc/bin/termrc before dns starts so that it would not
be necessary to start dns after pppoe.  (It's really
a bit of a bug that dns refuses to run without an
IP address in the first place).

If dns is already running, then it is not necessary
to echo refresh into any files after starting pppoe:
ppp (which pppoe runs) knows to do that for itself.

i was doing some tests. I was noticing when the system was starting rio and
reading the termrc a msg:

'can't read my ip address'

and the line that was causing that is the 'ip/ipconfig loopback ...'., so
i've commented that line and no more msg, well, so:

term% ip/pppoe -P
...
term% ndb/dns -r
term% ndb/dnsquery
> www.google.com
ip..
ip..
ip..
> ^D


well, the problem is that later i did that:

term% ndb/dnsquery
> www.gmail.com
... (nothing)

in other console i've tried with other url and nothing too..
when i try to open any url with abaco ou links both programs  stop working
(not responding)

I can ping IPs, so the problem isnt with pppoe (i think).

a bit more tests...

ip/ping -n 1000 in my ipgateway

lost almost 950.

ip/ping google, lost all (put it send the bytes)

dnsquery on www.google.com and www;gmail.com return ips, but i've tried
other ones
www.oi.com.br www.uol.com.br www.bell-labs.com and nothing (dns failure for
3)

i've ping the google ip too
ip/ping -n 1000 googleip
lost all.

it's strange when i pingED the gateway, the firsts almost 50 returned and
the others didn't.


Vester, my IP changes everytime i connect to the internet, it isnt an fixed
ip address.
and about the /lib/ndb/local network database file, i've read that i dont
need to care with it. to use ppp..

Sorry, just attempting to figure what you are missing if anything.
Russ is perhaps correct, however try the following:

Run off the live CD (Second option at the Plan 9 Startup Menu) and
attempt to connect via pppoe. I am interested to see if you have the
same issues.

I got this error msg: ip/pppoe: dial ether0!34915: '/net/ether0' cs: file
does not exist

In the first link i've posted says to verify if there is this file, if there
isnt,  add an entry to an 'table', but since i'm using the cd to boot i cant
modify anything there to use there.

Re: [9fans] pppoe configuration

but you can!

  start ramfs.  then copy the file you want to modify to /tmp.  then
edit
(i think the install might already have started ramfs for you.)
if files in /tmp are writable, it has.)  in either event, then cp $file /tmp and edit.
then bind /tmp/$file $file and you're done.

hmm ok, but
why are you interested in that?

do you think that can be an instalation error? (would be good if it was :D )

[-- Attachment #2: Type: text/html, Size: 143 bytes --]

Re: [9fans] pppoe configuration

[Russ Cox]

There was no installation error.

As I mentioned in an earlier email,
traces from ppp showed that there is a misinteraction
between Plan 9's ppp client and the ISP's ppp server,
which we did fix enough to get connected.  Unfortunately,
the ppp does not seem to stay connected for very long,
probably another ppp misinteraction.  It has nothing to
do with a failed installation: his binaries are fine (if buggy).

Editing /lib/ndb/local is also not the problem.
Ppp writes to /net/ndb with dns server and local
ip information (as does ipconfig's dhcp client) --
if you only have a single machine that is automatically
configured, you never need to touch /lib/ndb.

I wanted to rule out the possibility of it being an installation error
or a configuration error.

I'm glad you've made progress.

The following advice is assuming that you have a static global IP
address. I haven't had the opportunity to try this with a dynamically
assigned IP address.

Do you have a "dnsdomain=<yourdnsdomainname>" entry in /lib/ndb/local?
If no, then add it. Here's an excerpt from a working /lib/ndb/local
that you can use as a reference.

ipnet=tip9ugtitech ip=131.112.14.0 ipmask=255.255.255.192
	auth=mordor
	dns=131.112.14.2
