hi jurgen, perhaps it would be useful that you make your uml-kernel and bzipped root-fs available for download, so others could better help you solving this problem? > When I start port_helper from the > command line, it also finishes with the same message. does port_helpe have access to the socket? start port_helper under control of strace and analyze the output. perhaps you could get a clue, whats going on. regards roland ----- Original Message ----- From: <jur...@ph...> Cc: <use...@li...> Sent: Friday, December 05, 2003 8:28 AM Subject: Re: [uml-user] Building a minimum UML root fs > Thanks for all the suggestions.
