Run:
ifconfig -a
to check which "internet device" is used (usually eth0 and the like, eth1, etc).
Run
dhclient -v eth0
if the output of ifconfig -a was eth0 (else use eth1, or whatever you get)
Look at the file
/ etc /network/interfaces
(again for eth0, eth1, etc)
Moving OS'es from one harddisk to another one will have to remove:
/ etc /udev/rules.d/70-persistent-net.rules
I would not bet, but i think it must be excluded when doing snapshots (it gets created during boot). Perhaps that didn't work. Perhaps now there is an entry for eth0 in the interfaces file, but 70-persistent-net-rules does something different.
I hope that helps a bit, just some commands/ideas for troubleshooting, nothing close to a "solution".
So i herd u liek mudkip?

Wait, i think refract comes with wicd? Run that gui application and look at possible problems too
(or even start it from a terminal emulator, say xfce4-terminal, too look for error messages). It's wicd-gtk.

thank you for your answer
so it could be a conflit between wicd and network manager of gnome, because i use gnome shell as a descktop manager
i will try the commands you gived me and retourne her for feed back

hi!
first of all big thx for refracta snapshot. its the only tool so far making it possible to successfully create an iso over 4GB.
the reason i registered to the forums is the same i am posting in this thread.
i have the same problem with the internet connection not working in live usb (however it runs just fine when installed).
i am using refracta on kubuntu 14.04x64 btw.
what comments should i execute or where and when?

Are you using wicd to try and connect to a wireless network or what?
In other words, describe what you are doing, what is happening or not happening, etc...

this sounded very logical too me, and indeed i had a 70-persistent-net.rules file which i then deleted before doing a snapshot again. however, no success, the problem remains.

on my notebook i connect to the internet with the default wlan/network manager from kubuntu 14.04.
when i then try to boot that iso file in the virtualbox of my pc (connected via cable), i get no internet connection at all. however as soon as i install the file via refracta installer, internet connection is working again.
i think there must be some problem on refractas part, why the internet is not working in live cd mode, but having tried out so many other live distros they all have the internet working i think its just a small problem somewhere ...

Did you set the virtual machine for bridged networking and choose the right interface?
Are the kde network settings correct?
Can you try any of the commands that nadir suggested above?
