Proooooblem with Trixbox

i have a problem with eth0 not installed

trixbox is abandonware.

The brand and model of your PC are important. There have been reports of AsterikNOW failing to install on some because, by default, eth0 isn’t called eth0. Look at the archives for the workaround. You will probably need to re-install the OS.

i don’t understand you

The people who created Trxibox no longer support it and have removed the peer support forum from their web site. You should not be using it unless you are able to support yourself.
