ppp0 port down

Robb · 2012-07-22 14:46:53

Hi all,

I have succefully configured a pptp vpn connection on a Vbox machine running ubuntu and Network Manager which stays on the same lan of my magic Arch linux box but when I have tried to configure pptp vpn connection with pptpclient from my Arch box using the official Archwiki guide, using the same settings as Ubuntu vm, vpn doesn't start.

Settings of the succefull ubuntu connection are:
Connection name: tp
Gateway: x.x.x.x
Username: user
Password: password
NTDOMAIN: <blank>
Authentications used: PAP-CHAP-MSCHAP-MSCHAPV2-EAP
use Point-to-point emcryption MPPE: no
Allow BSD Data Compression: yes
Allow Deflate Data Compression: yes
Use TCP Header Compression: yes
Send PPP Echo packets: yes
---------------------------------------------------------
My Arch linux config is:

[robb@monkey vms]$ cat /etc/ppp/options.pptp | egrep -v "#"       
lock
noauth

[robb@monkey vms]$ sudo cat /etc/ppp/chap-secrets | egrep -v "#"
user      PPTP    password        *

[robb@monkey vms]$ sudo cat /etc/ppp/peers/tp | egrep -v "#"
pty "pptp x.x.x.x --nolaunchpppd"
name user
remotename PPTP
file /etc/ppp/options.pptp
ipparam tp

Now, I try to start ppp0:

[robb@monkey vms]$ sudo  pon tp debug dump logfd 2 nodetach
pppd options in effect:

... and it goes looping last lines.

By the way, the interface ppp0 seems down:

[robb@monkey network.d]$ ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

    link/ppp

I don't know what else I can try. I have been gone crazy for two months!

Any suggestion would be appreciated.

Robb.

Is my question stupid or in the wrong section?
