adsl connecting problems (ppp)

[corsair]

Hello,

I'm trying to replace my cisco router with a gentoo system. Unfortunately the DSL connection won't connect...

Code: Select all

And I'm not sure, what I'm doing wrong... ^^ Heck, this is the first time I'm setting up a connection other than ethernet in linux.

Here is the config:

Code: Select all

# /etc/conf.d/net
config_eth0=( "192.168.0.1/24" )

config_eth1=( null )

config_ppp0=( "ppp" )
link_ppp0="eth1"
plugins_ppp0=( "pppoe" )
username_ppp0="xxxxxxxxxxx@alice-dsl.de"
password_ppp0=
pppd_ppp0=(
        "debug"
        "noauth"
        "defaultroute"
        "usepeerdns"
        "holdoff 3"
        "child-timeout 60"
        "lcp-echo-interval 15"
        "lcp-echo-failure 3"
        noaccomp noccp nobsdcomp nodeflate nopcomp novj novjccomp
)

depend_ppp0() {
        need net.eth1
}

As you can see my provider is Alice DSL (Germany).. dunno if this has anything to do with it.

Configure your syslog daemon to save anything and post here the resulted logs.

thanks for the note.

I ran pppd from commandline with the nodetach option and figured out that the password is 'wrong'. The password does not get passed correct. I'm using baselayout 2, so there seems to be problems with it.

Though I figured out a working config: I've changed from using the password_ppp0 to "password xxxxx" in pppd_ppp0.

Code: Select all

# /etc/conf.d/net
config_eth0=( "192.168.0.1/24" )

config_eth1=( null )

config_ppp0=( "ppp" )
link_ppp0="eth1"
plugins_ppp0=( "pppoe" )
username_ppp0="xxxxxxxxxxx@alice-dsl.de"
#password_ppp0="xxxxxxxx"
pppd_ppp0=(
	#"noauth"
	"defaultroute"
	"usepeerdns"
	"holdoff 3"
	"child-timeout 60"
	"lcp-echo-interval 15"
	"lcp-echo-failure 3"
	"password xxxxxxxx"
	noaccomp noccp nobsdcomp nodeflate nopcomp novj novjccomp
)

depend_ppp0() {
	need net.eth1
}

it's not save to set the password option, because you can see the password in ps output, but it's working for the moment.

I'll open a bugreport against baselayout soon.

No, you will not. echo is an internal *sh command and, as such, do not appear on ps output.

[corsair]

sorry, I meant the password option of pppd, not the password_ppp0 option.

I read the following line in /lib/rc/net/pppd.sh:

Code: Select all

printf "%s" "${password}" | eval start-stop-daemon --start --exec /usr/sbin/pppd --pidfile "/var/run/ppp-${IFACE}.pid" -- "${opts}" >/dev/null

But this doesn't seem to work for me. I tried the follwoing command, which should be the one run by rc manually and it doesn't seem to work (replaced printf with echo):

Code: Select all

$ echo "xxxxxxxx" | /usr/sbin/pppd unit 0 user xxxxxxxxxxx@alice-dsl.de remotename ppp0 linkname ppp0 nodetach defaultroute usepeerdns holdoff 3 child-timeout 60 lcp-echo-interval 15 lcp-echo-failure 3 noaccomp noccp nobsdcomp nodeflate nopcomp novj novjccomp plugin passwordfd.so passwordfd 0 defaultmetric 4004 maxfail 0 persist connect true plugin rp-pppoe.so eth1

ah, I've checked with the stable version of baselayout.

see if [bug=203860]bug 203860[/bug] help you with this thing.

Edit later: uberlord says printf is interpreted as internal command in bash, so unless you are using busybox, there is nothing wrong in using printf instead echo.

Iv'e also had some quite irritation problems with my router the last few days after moving from the rp-ppoe package to ppp. I was reformatting the server and followed the gentoo "home router guide". At first everything seemed fine, but the users on my local net couldn't open certain web pages. I googled it and many people said that it could be the MTU value... After playing around with this value I came nowhere....

Finally i decided to give rp-pppoe a try. It worked as a charm, not problems at all. Just used pppoe-setup and away we go...

That is because you didn't searched this forum properly. Time and time again I've posted here the solution to this problem, not to mention this quote from /etc/conf.d/net:

#WARNING: if MTU of the PPP interface is less than 1500 and you use this
#machine as a router, you should add the following rule to your firewall
#
#iptables -I FORWARD 1 -p tcp --tcp-flags SYN,RST SYN -j TCPMSS --clamp-mss-to-pmtu

Finally i decided to give rp-pppoe a try. It worked as a charm, not problems at all. Just used pppoe-setup and away we go...

Fine, just don't complain when rp-pppoe baselayout support will be finally removed.

I'm having problems with the connection to alice-dsl too (here is the post).
I copied your configuration but it didn't work. What modem do you have?
Mine is a "Thomson SpeedTouch 350i".
Did you have to do something "special" before/after pppd configuration in order to get it working?
