Have you configured the dns?

edit /etc/resolv.conf (create one, if not present). Add your favourite dns server, for e.g.

nameserver 8.8.8.8
nameserver 8.8.4.4

i done it but same error

When ifconfig shows ppp0 connected, try to ping an ip instead of the website name, and post the result here:

ping -c 4 8.8.8.8

Also post your rc.conf.

PS: please embed the rc.conf in code tags, or use a pastebin.

when i ping i get
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.

this is rc.conf

Hmm.. everything looks fine rc.conf. I have no idea, what's wrong. Is dhcp working fine?

Also, if you haven't already, take a look here:

https://wiki.archlinux.org/index.php/Co … ng_Network

Also, if you are in a hurry, go to the irc channel, and ask someone for help there.

I don't think 8.8.8.8 responds to ICMP packets.
Try this site belonging to the best darn Linux distribution out there ping 66.211.214.131

Well, i can ping 8.8.8.8 (it's google dns's primary server, for those who don't know).

Interesting. I could not from home last night. I can from work. I also just ssh'ed home and tried, and now it works

I knew it was goggle's DNS server; I don't think that means it is required to respond ICMP packets; but apparently it does.

are you using PPPoE/ADSL or not? if yes, why do you use dhcp?

when you setup your connection with pppoe-setup, set DNSTYPE to SERVER if you don't know your DNS nameserver's.

remove network from DAEMONS array, and netfs too if you don't use network filesystems.

...
#Static IP example
#eth0="eth0 192.168.0.2 netmask 255.255.255.0 broadcast 192.168.0.255"
#eth0="dhcp"
INTERFACES=(!eth0)
...
DAEMONS=(syslog-ng crond adsl)

Maybe it's routing program ？
Encounter similar program today when using a live USB
LAN: DHCP -> eth0
WAN: PPPoE -> ppp0

`ifconfig` show both eth0 and ppp0 with right IP address
`ping` host on LAN reply normally

But `ping` host on WAN always fail ( tried www.google.com, 8.8.8.8...etc)
So I look into route table

[left]$ route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
h254.s98.ts.hin *               255.255.255.255 UH    0      0        0 ppp0
192.168.1.0     *               255.255.255.0   U     0      0        0 eth0
default         *               0.0.0.0         U     0      0        0 eth0

the default gate way is using Interface eth0
after changing it to ppp0
Solved my problem

[left]$ sudo route del default
[left]$ sudo route add default ppp0
[left]$ sudo /etc/rc.d/network restart
[left]$ sudo /etc/rc.d/adsl restart
