Currently, it only logs login attempts. You could configure auditd to watch file creates, deletes, and renames, in the /dev/ directory. This database is most likely configured to ignore /dev/ and other 'special' filesystems. –lk- Aug 13 '12 at 19:01 fair enough, but I don't see it when I look By the way, is the sequence \)-+ in your command intentional?

Perhaps Apple ceased to create the /dev/urandom because it is unnecessary? http://sauvblog.com/cannot-read/cannot-read-from-index-cache-directory.html more hot questions question feed about us tour help blog chat data legal privacy policy work here advertising info mobile contact us feedback Technology Life / Arts Culture / Recreation Science I tried googling to figure out how to install this file, but I have come up empty. let us know how it goes.

Otherwise the UNIX piping mechanism seems to get blocked because tr keeps reading from /dev/urandom but for some reason refuses to write to its stdout. It is a typo mistake.

Thanks. Executed in Terminal.app though the following command runs without any hiccups: sh -c 'LC_ALL=C tr -cd [:alnum:] < /dev/urandom | fold -w30 | head -n1; echo;' Another approach would be to Besides this, you must use full path to command binary, e.g. This site is not affiliated with Linus Torvalds or The Open Group in any way.

I know it sounds silly to even suggest it, but the fact that your /dev/urandom disappeared at all is definitely strange, and it might happen again. Instead of messing around with enviornment varialbes, use perl in place of tr: perl -pe 'tr/A-Za-z0-9_\!\@\#\$\%\^\&\*\(\)-+=//dc;' < /dev/urandom | head -c 32; echo This has the advantage of being portable between Its support for standard linux stack and GPIOs makes it easy to implement any embedded system protocols.

Maybe its also mixed up with the followign line that in my main.cf contains the home_mailbox containing "Maildir/" that is also mentioned in your errormessage, so maybe just a newline is Select 2D data in a certain range Converting the weight of a potato into a letter grade Execute bash script from vim Wrong way on a bike path?
