The "c" means that it is a special file to begin with; you cannot just set this property for an existing normal file. Such special files used to be created with the "mknod" command, but nowadays udev should take care of their creation. > Would it be OK to just chmod 666? The permission error will probably be gone then, but it would still be a normal file and not a real /dev/null, which is used to dump the output of all sorts of commands that are called in scripts. (The job of /dev/null is to swallow input without a trace.) I would remove (or rename) the file and run udevtrigger as root, followed by echo "xxx" > /dev/null That should force udev to create the device node. Afterwards you should see this: $ file /dev/null /dev/null: character special (1/3) If that does not work then something is wrong with your udev configuration. The first thing to check is if the relevant rules exist: $ grep null /etc/udev/* /etc/udev/links.conf:M null c 1 3 /etc/udev/permissions.rules:KERNEL=="null", MODE="0666" If all else fails then you could try to create the device node yourself (as root): mknod -m 0666 /dev/null c 1 3 However, if udev is active it will normally intercept this command and redirect the device node creation to /dev/.static/dev/null (AFAIK). -- Regards, | http://users.icfo.es/Florian.Kulzer Florian | -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
