[9fans] adsl via pptpd

[William S.]

It has been a while since I last posted/read to this list
and since then I have obtained adsl service through xs4all
here in the Netherlands.

In order to do that I use an ethernet card and an isdn modem.
Some of the configuration details to do this on Linux are posted
below. Will this hardware setup work with Plan9? Which files
would have to be changed in Plan9 to make the connection?

install pppd
install pptp

configure network adapter

% ifconfig eth0 netmask 255.255.255.0 broadcast 10.0.0.255 10.0.0.150

% ifconfig eth0 up

% ifconfig eth0

set up route

% route add -net 10.0.0.0 netmask 255.255.255.0 eth0

% route -n

configuring pppd

% cd /etc/ppp

% mv options options.modem

% touch options

creating the file contents /etc/ppp/options.adsl

idle 0
noauth
user me@xs4all-basic-adsl
defaultroute
usepeerdns
nodetach
lcp-echo-interval 10
lcp-echo-failure 3

creating the file contents /etc/ppp/pap-secrets

# Authenticate via PAP
# login - server - pass - IP
me@xs4all-basic-adsl * mypassword *

starting the service

% /usr/sbin/pptp 10.0.0.138 file /etc/ppp/options.adsl

On Plan 9, you should be able to do

	cd /sys/src/cmd/ip
	hget http://plan9.bell-labs.com/plan9/pptp.c >pptp.c
	mk pptp.install
	mk clean

	ip/ipconfig ether /net/ether0 10.0.0.150 255.255.255.0
	ip/pptp -P -s me@xs4all-basic-adsl:mypassword 10.0.0.138

	ip/ping 204.178.31.2

You probably need to do

	echo '	dns=1.2.3.4' >>/net/ndb
	echo -n refresh >/net/cs
	if(! test -f /srv/dns)
		ndb/dns -r

(Look in /etc/resolv.conf on Linux after doing pptp to see what
your dns server should be.)  The pptp client is almost entirely untested.
Let me know of any problems.
