Re: /etc/cron.daily/man-db: /var/cache/man: Permission denied
I think it's a problem with the way exim is configured. Exim is mailing the report locally. So that's why we couldn't find anything about cron-daily, man-db, or file permissions ! I can see the same error on two freshly installed Debian unstable boxes, with completely different archs and settings. I need to track it further, just wnated to drop a note to the archives. See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=209185 keep it rolling micha -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]

/etc/cron.daily/man-db: /var/cache/man: Permission denied
(Please first cc to me, if i got a reply i will switch to reading the archive) Hello, This is Debian Sid, and since a few months i got this error message (sent via local mail): /etc/cron.daily/man-db: find: /var/cache/man: Permission denied and i just can't come up with any explanation. Perhaps somone can give me a hint ? This is what i can find so far: /var is mounted as: /dev/hda10 on /var type ext2 (rw,nosuid,nodev,errors=remount-ro) The permissions are: drwxr-xr-t 17 root root 4.0K 2006-04-02 03:00 /var drwxrwxr-x 26 root root 4.0K 2006-08-12 20:49 /var/cache/ drwxr-sr-x 16 man root 4.0K 2006-08-18 00:06 /var/cache/man The last one contains: drwxr-sr-x 2 man root 4.0K 2004-05-25 02:03 cat1 drwxr-sr-x 2 man root 4.0K 2004-05-15 16:49 cat2 drwxr-sr-x 2 man root 4.0K 2004-05-15 16:49 cat3 drwxr-sr-x 2 man root 4.0K 2004-02-02 10:48 cat4 drwxr-sr-x 2 man root 4.0K 2004-05-24 02:25 cat5 drwxr-sr-x 2 man root 4.0K 2003-07-23 02:36 cat6 drwxr-sr-x 2 man root 4.0K 2004-03-11 07:47 cat7 drwxr-sr-x 2 man root 4.0K 2004-05-25 02:03 cat8 drwxr-sr-x 2 man root 4.0K 2004-05-17 04:07 cat9 drwxr-sr-x 3 man root 4.0K 2006-08-18 00:06 fsstnd -rw-r--r-- 1 man root 2.0M 2006-08-16 00:15 index.db drwxr-sr-x 3 man root 4.0K 2006-08-18 00:06 local drwxr-sr-x 3 man root 4.0K 2006-08-18 00:06 oldlocal drwxr-sr-x 2 man root 4.0K 2002-03-18 13:08 opt drwxr-sr-x 7 man root 4.0K 2006-05-07 15:58 X11R6 None of the subdirectories of /var/cache/man contains any file, (besides some index.db ). Apparently, manpages are stored in /usr/hsare/man, instead, but that has drwxr-xr-x 34 root root 4.0K 2006-05-28 13:00 man/ on all levels. - Which seems a little bit weird to me; but /var/cache/man seems to have been installed by package man-db, too. I can see man-db 2.4.3-3 and manpages 2.34-1 are installed. Well, maybe that's not actually Sid but 'testing' since i downgraded the sources list to 'testing' some week ago, but it will last some more weeks until a full turnover, and the error message was sent afterwards and all the time anyway. The cron.daily script will re-create a missing /var/cache/man with exactly the existing permissions: if ! [ -d /var/cache/man ]; then # Recover from deletion, per FHS. mkdir -p /var/cache/man chown man:root /var/cache/man chmod 2755 /var/cache/man and /etc/crontab has all cron scripts running as root. Maybe this here is the bit of the script which leads to the error ? start-stop-daemon --start --pidfile /dev/null --startas /bin/sh \ --oknodo --chuid man -- -c \ find /var/cache/man -type f -name '*.gz' -atime +6 -print0 | \ xargs -r0 rm -f I have lrwxrwxrwx 1 root root 4 2006-07-24 18:21 /bin/sh - bash* The 'man' command is aliased for 'root' by a function here (invoking pinfo) but i assume system calls it always by full path: lrwxrwxrwx 1 root root 17 2006-08-12 20:50 /usr/bin/man - ../lib/man-db/man -rwxr-xr-x 1 root root 85K 2005-09-21 14:23 /usr/lib/man-db/man So...what ? ° /\/

So, semantically, those permissions are just rwxr-x-r-x, and even if yuur user is in the 'root' group, he cannot view the directory contents (because 'x' in a directory means permission to enter view the contents).

And, even though 'dfox' is not a member of the root or man groups, user dfox (that's me) can run 'find man' in /var/cache/, which lists all subdirectories underneath man, or find . inside man, which lists a number of directories where local man pages are kept (that's what the directory is for, by the way). Even so, the permisions would seem correct (the third r-x is other, and since I am not a man :) or a root, I am an other, and this is all good, because I can view files (-r) or go into the directorty (-x) but an unable to write anything therein. drwxr-xr-x 34 root root 4.0K 2006-05-28 13:00 man/ on all levels. - Which seems a little bit weird to me; but /var/cache/man seems to have been installed by package man-db, too.

The way this ought to work (and I thought it did) was for example, a hypothetical user looks at a frequently used man page (like man ls). Since it takes more time to process the man page than display it, a local copy is in /var/cache/man/appropriate sect4ion (in this case, cat1) for later perusal. Man would see that a processed page was in the appropriate place, and display it. After a time, the old entries in those cache directories would be deleted. But, I have 0 bytes in all directories, and an overall usage of 1464K, because of a large index.db. (That file was changed 2 days ago.) -- David E.
