Bug 55810

 	I need to have two tunnel devices. One is for internet connection, 
 	wich is PPPoE, the other one is for a PPPoSSH session - to connect 
 	to my company via a VPN. During startup, I enabled ppp to dial to
 	Internet in the rc.conf script.
 
 	# PPPoE for DSL
 	ppp_enable=YES
 	ppp_mode=ddial
 	ppp_nat="no"
 	ppp_profile="arcor-dsl"
 	ppp_user="root"
 	
 	When I want to connect to my company I simply start ppp. PPP then 
 	answers with an error message which kills my PPPoE session to the
 	Internet. The error messages logged by /var/log/messages
 	Aug 20 17:23:40 circa ppp[935]: Error: bundle_Create: ioctl(TUNSIFMODE): Device busy
 	Aug 20 17:23:45 circa ppp[225]: tun0: Error: ip_Input: deflink: wrote 56, got 0
 	Aug 20 17:23:47 circa last message repeated 3 times
 	Aug 20 17:23:47 circa ppp[225]: tun0: Warning: iface rm: ioctl(SIOCDIFADDR, 213.23.24.183 -> 145.253.4.4): Can't assign reques
 	ted address
 
 	I then have to kill my ppp, start the internet again and then open
 	the PPPoSSH session. After the first fail, everything is fine. So I 
 	have to go through this procedure only once - just after reboot.

Fix: 

Okay, here are the commands from the shell

	ppp
	quit
	ps ax|grep ppp
 	 941  ??  Ss     0:00.61 /usr/sbin/ppp -quiet -ddial arcor-dsl
	kill 941
	/usr/sbin/ppp -quiet -ddial arcor-dsl
	ppp
	Working in interactive mode
	Using interface: tun1
	dial sparta
How-To-Repeat: 	To have a full documentation, here is my ppp.conf
#
# ppp.conf: PPPoE configuration
#

default:
 set log phase tun

 # download /etc/resolv.conf
 #enable dns

arcor-dsl:
 # PPP over Ethernet
 set device PPPoE:rl0
 set speed sync
 set mru 1492
 set mtu 1492
 set ctsrts off

 # monitor line quality
 enable lqr

 # log just a bit
 set log phase tun

 # insert default route upon connection
 add default HISADDR

 # User / Pass
 set authname * (changed for report)
 set authkey  * (changed for report)

sparta:
 set device !/etc/ppp/sparta
 set speed 115200
 set mtu 800
 allow users root hannes raveboy
 set timeout 0
 set log phase chat connect lcp ipcp command
 set dial
 set login
 set ifaddr 192.168.3.1 192.168.3.2
 set server /var/tmp/loop "" 0177

	And the "/etc/ppp/sparta" file
	#!/bin/sh
exec ssh -C -c blowfish raveboy@82.**.**.77 -i ~/.ssh/raveboy\@sparta.key '/usr/sbin/ppp -direct scheme'
	(IP Changed, becaus I don't want to show it to public!)
