I'm running FreeBSD-4.8. Sometimes the file permissions for /dev/null get mysteriously changed by some unknown process to: crw------- 1 root wheel 2, 2 Sep 2 11:20 /dev/null This has a devastating effect on user processes that want to open /dev/null. Whenever my system starts acting funny, the first place I look is at the permissions for /dev/null. When I find them changed I go under root and execute: chmod 666 /dev/null to get things back to normal. Has anybody seen this before? Have I got a hidden umask set up wrong somewhere, or is one of my daemons the culprit? Or could it be happening during the time that I run as root doing system maintenance? Ed Alley
