This could be a configuration topic. In /etc/ttys you can intendedly disable consoles (virtual terminals). If this has been the case, trying to login locally won't work. You could try to boot the system from a live CD or DVD to check the configuration. If you can reboot the machines, try to enter into single user mode. In this case, local console login usually is enabled, but it may require the root password. See "man 5 ttys" for possible details. > This is important.

As it has been mentioned, connecting a PS/2 keyboard to a running machine can be a really bad idea - even causing a defect of the PS/2 keyboard connectors. And with USB, you're mostly unlucky on FreeBSD 4 machines due to the lack of kbdmux / automatisms like via devd. > I couldn't plug in the keyboard then reboot the server to get access to > the console. If configured properly, it should be sufficient to press the power key to initiate a controlled system shutdown. This should give you the chance to try SUM or a live CD. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
