I been trying to connect to the Internet. But my ppp.conf doesn't work. "ppp -auto test2" gives an error:

"warning ppp[11941]: tun0: warning: chatscript failed
using interface: tun2
warning add route failed: 0.0.0.0/0 already exists.
last message repeated 6 times
tun1 warning chat script failed."

/etc/ppp/ppp.conf:

default:
set log Phase Chat LCP IPCP CCP tun command
set device /dev/cua01
set speed 115200
set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \"\" AT OK-AT-OK ATE1Q0 OK \\dATDT\\T TIMEOUT 40 CONNECT"

test2:
set phone 021245897
set login "ABORT NO\\sCARRIER TIMEOUT 5 ogin:--ogin: ppp word: ppp"
set timeout 120
set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.0 0.0.0.0
add default HISADDR
enable dns

test1:
set phone 0000000
set login
set authname Name
set authkey passwd
set timeout 120
set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.0 0.0.0.0
add default HISADDR
enable dns

"ifconfig tuno" is:

"tun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 3000"

the routing table looks like this:

Routing table [netstat]:

Internet:

224/4 127.0.0.1 URS 0 0 33224 lo0

/var/log/messages gives me:

Jul 27 08:09:39 leet ppp[16772]: tun0: Warning: Chat script failed

Any help would be much appreciated.
