Hi all, I made the mistake of trying to run greyscanner <http://www.ualberta.ca/~beck/nycbug06/scripts/greyscanner>; as a regular user. Now, everytime it runs (every 30 minutes), there is a cron error from user "operator" complaining that "you need to be root" to run /usr/libexec/save-entropy. Moreover, each time this happens, an instance of greyscanner, belonging to user operator, remains dormant in memory, which means an additional instance of perl. After a day or so most of my swap memory is used. up. I have tried killing every PID associated with user operator and/or greyscanner, but like Lazarus the thing keeps rising from the dead every 30 mins. I can't figure out what process is keeping it alive. FWIW, here is the relevant snippet from the script: # daemonize and scan in a loop. &daemonize; while (1) { setlogsock('unix'); openlog("greytrapper", 'pid', 'mail') || die "can't openlog"; syslog('debug', "Scan started"); my $pid; $pid = fork(); if (!$pid) { # child. scan away... &scan; exit(0); } # parent waits and sleeps. wait; syslog('debug', "Scan completed"); sleep($SCAN_INTERVAL); } I am not a perl programmer, and it is not immediately obvious what is going on here. So, how to I kill this bugger once and for all? Thanks. $ uname -r 7.0-PRERELEASE -- Colin Brace Amsterdam http://lim.nl
