Package: udev Version: 0.105-4 Severity: normal
Hi, as the subject says, sometimes the permissions of /dev/null, /dev/(u)random and some others gets set to 0660, which obviously is not very useful. It's not related to rebooting, but happens at odd times when the system is otherwise up&running fine. Searching around on the 'net didn't prove very useful (only some reports without a real solution, for Ubuntu and Slackware variants of udev). grep-ing the /etc/udev* brought no enlightenment either, but running (as suggested in /usr/share/doc/udev/README.Debian.gz) /usr/share/doc/udev/examples/udevtest-all indicates (for a mere sysadmin like me) that somehow udev's to be blamed here: ... main: looking at device '/class/mem/null' from subsystem 'mem' udev_rules_get_name: no node name set, will use kernel name 'null' udev_db_get_device: found a symlink as db file udev_device_event: device '/class/mem/null' already in database, validate curren tly present symlinks udev_node_add: creating device node '/dev/null', major = '1', minor = '3', mode = '0660', uid = '0', gid = '0' ... Any hints? FWIW, this machine's acting as Xen dom0, but this also hit us on some domUs. cheers, Robert Waldner -- Package-specific info: -- /etc/udev/rules.d/: /etc/udev/rules.d/: total 56 -rw-r--r-- 1 root root
