Apologies for the earlier ls -l output, that was from a user process, not a root job. It really looks like: [root@lx3]# ls -l /dev/misc total 0 crw-r--r-- 1 root root 10, 62 Jul 21 06:24 dlm-control crwxrwxrwx 1 root root 10, 61 Jul 21 06:24 dlm_default crwxrwxrwx 1 root root 10, 59 Aug 18 09:15 dlm_play crwxrwxrwx 1 root root 10, 60 Jul 21 06:26 dlm_testls The problem is that /dev/misc was missing x permission: drw-rw-rw- 2 root root 4096 Aug 18 09:15 /dev/misc/ Changing this to drwxrwxrwx 2 root root 4096 Aug 18 09:55 /dev/misc/ allows non-root jobs to connect to namespaces based on the namespace's permissions.
