Probably /etc/resolv.conf inside chroot does not have valid DNS servers.
Try to
cp /etc/resolv.conf /chroot/path/etc/ .

Hi,
to chroot on desktop, you need quemu-user
(http://www.gentoo.org/proj/en/base/embedded/handbook/?part=1&chap=5).

Get your phone an ip address?
# ip addr

What is in /etc/resolve.conf? What say 'dig @8.8.8.8 gentoo.org'? What
say ping 8.8.8.8?

Regards,
Andrej Gelenberg

*** questions ****
should i copy the /etc/resolv.conf from the desktop to the phone? the
name server form the provider (saunalathi) should be the same.
8.8.8.8 is the google DNS server - is this the better choice?

I try to install qemu-user:
# USE=static emerege -b1 app-emualtion/qemu-user
[...]
!!! All ebuilds that could satisfy "app-emulation/qemu-user" have been masked.
[...]

I guess I have first to get the wi-fi proper working in SHR and then
try to install gentoo from scratch, then at the moment seems to be the
biggest problem, that I have no internet access to the phone at all.
What do you think?

So long, Elmar

Hi Peter,

Thank you as well for the fast reply.
I guess you have seen my longer answer to Andrej.
Your answer make me optimistic to use the DNS names server information
that works on my desktop in my phone.
lets see what happens...

So long, Elmar

Hi Peter and Andrej,

It did not help. I get the same errors, using the reslov.conf file
from the desktop in the shr and gentoo environment on the phone.

Have a good night, all of you, Elmar

yes, it is.

You can get list of urls which you need with 'emerge -pvf layman'. Place
downloaded files into /usr/portage/distfiles and install layman.

hmm, your wifi uses the same subnet as the usbconnection.
What does

route -n

show? I don't know if linux networking/routing can correctly handle such
situation... To be on the safe side you can delete the address on the
usb interface
ip addr del 192.168.0.202/24 dev usb0

copy (do not symlink) over the one from the normal system

Why not connect it through the usb? It might be slower than wifi, but
much more stable and predictable... It's on wiki:
http://wiki.openmoko.org/wiki/USB_Networking

but if you have working connection from desktop to neo, you just need to
run

iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -j MASQUERADE
echo 1 >/proc/sys/net/ipv4/ip_forward

on the desktop, shr should be by default set up for the usb connection,
unless you start up some wifi connection app which would mess it up,
however this is what it looks like here (on the moko, wifi turned off):

root@om-gta02 ~ # cat /etc/resolv.conf

Do I still have to run
iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -j MASQUERADE echo 1
>/proc/sys/net/ipv4/ip_forward ?

Still wonder if the problem is in the shr installation. I just flashed
freerunner whit shr, to be able to install gentoo. I never properly
used it to phone or something. The pre-flashed os (om2008?) have not
even had a command line. But there the phone was working. That I
tested.

Well, that's it for today.
Thanks! And good night.

So long, Elmar

is sshd running?

is the last line needed because neo uses the same subnet as your
regular network?
If so, i would try to move neo to some other subnet, just to be sure the
prob. isn't there.... ie change 192.168.0.. to say 192.168.47... in
/etc/network/interfaces and reboot/restart eth0

hmm, i'd double check that your ssh is really running, that your
firewall is correct ;) and that sshd is listenning on all
addresses/interfaces (ie 0.0.0.0) and not only your interface/address you use
for your local network...

tabletka ~ # netstat -lpn | grep :22
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 2985/sshd
tcp6 0 0 :::22 :::* LISTEN 2985/sshd


it's pretty weird that desktop -> moko connection works and reverse not,
as even for the first one, packets have to be routed from moko to
desktop... unless there's some firewall stuff that allows only outgoing
connections on the desktop or something like that...

you didn't start wifi, so it isn't turned on and the interface isn't even there...

heh, some formatting issue, they should be 2 commands...
but anyway... you need them to make your desktop act as gateway/NAT for
the neo, ie to forward packets to the outside network and back....
but they are not needed for the simple neo <-> desktop connection

i have a bit more than half a year old shr, never had a problem with the
usb connection...

Hi Andrej, Peter, Yoyo, and David,

I was quite in a hurry the last two weeks, that is why I not have
replied. Sorry.

But this weekend finally i got the desktop:freerunner usb networking
running. The crack point was at the desktop linux distro I use
(gNewSens) not at shr.
I list here my solution:

1) David / Yoyo: is sshd running?
It was not. I had even to install and start it:
elm@firebolt:~$ sudo apt-get install openssh-server
elm@firebolt:~$ sudo /etc apt-get install ssh
elm@firebolt:~$ sudo /etc/init.d/ssh start
elm@firebolt:~$ ps aux | grep -i ssh
root 4950 0.0 0.0 5320 996 ? Ss 20:28 0:00 /usr/sbin/sshd
elm 6679 0.0 0.0 312 108 pts/0 R+ 20:50 0:00 grep -i ssh


2) Yoyo: you often asked me about the subnetwork.
The mayor problem was that the subnet between the freerunner (eth1:
192.168.0.something) and the desktop (eth0: 192.168.0.57) was
overlapping. My solution is to move the eth1 usb connection to the
freerunner form 192.168.0.0/24 to 192.168.202.0/24.
The majority of the needed information I learn from the following pages:
http://wiki.openmoko.org/wiki/USB_Networking
http://lists.openmoko.org/pipermail/support/2008-August/#1277
http://lists.openmoko.org/pipermail/support/2008-August/001282.html
http://lists.openmoko.org/pipermail/support/2008-August/001288.html
http://lists.openmoko.org/pipermail/support/2008-August/001300.html

In practices it looks like this:
*** on freerunner ***
root@om-gta02 ~ # /etc/init.d/networking stop
root@om-gta02 ~ # vi /etc/network/interfaces
[...]
# Ethernet/RNDIS gadget (g_ether)
