As of my STABLE upgrade to the 8:00 GMT Saturday version, I have noticed that ps(1) is behaving differently. Unless run by root, "ps -ax" refuses to print the command line associated with each process. I've checked a couple things: 1. /bin/ps is not SGID kmem and /dev/kmem permission is set to 0640, but that isn't the cause of this problem (though it may cause others, since the ps(1) man page says it needs to read /dev/kmem). 2. /proc/*/cmdline is owned by root:wheel and has 0444 permissions. It should therefore be usable by ps(1) regardless of who runs it. So it looks like command lines should print, but they don't. Does anybody know what's happening here? -- M/S 258-5 |1024-bit PGP fingerprint:|tweten@nas.nasa.gov NASA Ames Research Center | 41 B0 89 0A 8F 94 6C 59| (650) 604-4416 Moffett Field, CA 94035-1000| 7C 80 10 20 25 C7 2F E6|FAX: (650) 604-4377 Not an official NASA position.
