The permissions on /dev/null are indeed set to 0600 (for whatever reason) and running a "sudo chmod 666 /dev/null" rectifies this problem. However, upon rebooting, the perms on /dev/null return to 0600. I am having this problem on another one of my Ubuntu boxen and I've no clue what I did to prompt it. My only guess was a system update.
Yeah, changing the permissions via /etc/rc.local was what I ultimately ended up doing shortly after posting the original thread. It works but, like others here, I would still like to know why this is happening in the first place. It's happened on 2 out of 3 of my Ubuntu machines (and I "treat" them all alike--I didn't do anything special to the 2 that gave me problems), and it's obviously happening to others.
I should probably file a bug report but I don't know how...
