Do not work for me. And to point directly to the slirp program instead of its folder (which is understood by many as the *path* for anything, not the things themselves, with full path) is news for me, and something that should be pointed in the docs. I think many others will understand it as I did before you said this. Now there is a few lines about slirt and ETH0: ======================= [autodetect SLIP/CSLIP, MTU 1500, MRU 1500, 115200 baud] SLiRP Ready ... Unsupported device type 256 for "eth0" Failed to bring up eth0. done. ======================== What can I do? > Then you can use networking.

If so, please say how, so I don't have to search and find what is already known. Thank you -- http://www.fastmail.com - Email service worth paying for.
