Trying this out. I've seen this situation twice. This time i finished it us by following method:
The problem seems to be with the permissions of the /dev/null. This seems to be read only at the moment for you. Check this by logging in as root and listing it with the command:
ls -l /dev/null You should see this if everything is correctly set: crw-rw-rw- 1 root root 1, 3 If you get a different set of permissions like this maybe: -rw-r--r-- 1 root root 1, 3 then you should (as root) delete the /dev/null with: rm /dev/null and recreate it (as root) again with: mknod -m 0666 /dev/null c 1 3 (The device number according to the Kernel source in the documentation under Documentation/devices.txt supposed to be Major=1 und Minor=3) But i still remember that one time i confronted with another situation which cannot be handled with this one. I will catch it up when i find out.
