Have you added eth0=tuntap,tap0 to the cmd line of UML according to: http://user-mode-linux.sourceforge.net/networking.html (See section "TUN/TAP with a preconfigured tap device") > eth0: ERROR while getting interface flags: No such device > Bind socket to interface: No such device > exiting. > > > I also get several thousand lines of error message like the following > > line_ioctl: tty0: ioctl KDGKBTYPE called > line_ioctl: tty0: ioctl KDGKBTYPE called > line_ioctl: tty0: ioctl KDGKBTYPE called > line_ioctl: tty0: ioctl KDGKBTYPE called > line_ioctl: tty0: ioctl KDGKBTYPE called > line_ioctl: tty0: ioctl KDGKBTYPE called > Couldnt get a file descriptor referring to the console > line_ioctl: tty0: ioctl KDGKBTYPE called > line_ioctl: tty0: ioctl KDGKBTYPE called > line_ioctl: tty0: ioctl KDGKBTYPE called > line_ioctl: tty0: ioctl KDGKBTYPE called > line_ioctl: tty0: ioctl KDGKBTYPE called > line_ioctl: tty0: ioctl KDGKBTYPE called > Couldnt get a file descriptor referring to the console These errors can be safely ignored, normally. -- Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".
