SCSI and ISDN have the equivalent devices of the "lo" driver for the networking layer. Or the equivalent of tun/tap devices for the ethernet layer. It just have to be an config.in option in UML and every other adapters switched off. The problem is: I still do not really get how UML really works. Many of the mapping rules (Kernel machanism on normal arch -> UML) are not quite clear to me. Is there a paper or sth. like that describing the design a bit more in detail? I only found usage papers on the user-mode-linux home page. Regards Ingo Oeser -- 10.+11.03.2001 - 3. Chemnitzer LinuxTag <<<<<<<<<<<< been there and had much fun >>>>>>>>>>>>
