hey guys and girls, i have been told many times i should run gentoo due to the lacking in power of my boxes (less clutter=good thing) so i downloaded and burned the 1.4 LiveCd iso at a buddies house and went home to install my copy,i installed it easy enough (although compile time is a b*tch) i configured and installed my kernel easy enough as well as setup grub, i made sure i had rp-pppoe emerged in the chroot enviornment umounted everything and rebooted, everything appears cool, grub loads and boots the kernel, i get the login prompt and login, and attempt to setup adsl, "# adsl-setup" everything is good so far, "# adsl-start" " ..Conncted!" sweet... first things first i need to start downloading some stuff "# emerge lynx" after attempting to connect to the server for a few minutes the program tells me its having trouble resolveing the server, so i try ifconfig everything looks ok, so i assume it may be a problem with emerge, i type "# ping -c 3 www.google.com" again, no outgoing connection: i assume hrmm,
trouble resolving dns, i "# nano -w /etc/resolv.conf" and jot down an ip of one of my name servers and try to ping to no avail, now a bit bummed and two bags of sun flower seeds and a pack of smokes later i still cant figure it out, any advice?

thanks in advanced, doc.

I too have rp-pppoe running and it works perfectly.

Try pinging the IP of google (216.239.39.99) instead of the DNS-name.
If this works, it is a DNS problem. Otherwise check the route:
Code:
root@rincewind:~# route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
217.5.98.2      0.0.0.0         255.255.255.255 UH    0      0        0 ppp0
192.168.42.0    0.0.0.0         255.255.255.0   U     0      0        0 eth0
127.0.0.0       127.0.0.1       255.0.0.0       UG    0      0        0 lo
0.0.0.0         217.5.98.2      0.0.0.0         UG    0      0        0 ppp0


adsl-setup asked you for an DNS server to use. The special entry "server" (afair) means that the ISP gives the DNS addresses which are stored in /etc/resolve.conf after the connection is established. Check this.

Do you have a firewall that doesn't let anything out?

>> thanks for your input man, i'm about to boot into the install and check the route, i dont have a firewall working on it yet, and the adsl-setup is fine (same information i've entered in a few diffrent OSes) i had preveously assumed it may be a problem with name resolution but, i tried to ping one of my name servers taken from "/etc/resolv.conf"(ip address that is) and it did nothing, i'm now assumeing its a kernel level issue as i was under the impression that gentoo is to be networking ready out of the box<< thanks :) doc.
