These 3 lines of code: if (fork()) {sleep 10; exit(0);} $SIG{'CHLD'} = 'IGNORE'; exit(system("/usr/lib/nagios/plugins/check_ping -H google.com -w 500,20% -c 1000,40% 1> /tmp/stdout.txt 2> /tmp/stderr.txt; echo $? > /tmp/res.txt"));
return "PING WARNING - Packet loss = 0%, RTA = 62.08 ms|rta=62.077999ms;500.000000;1000.000000;0.000000 pl=0%;20;40;0" into /tmp/stdout.txt and 256 into /tmp/res.txt (/tmp/stderr.txt remains empty). If I comment out the 2nd line, it returns "PING OK - Packet loss = 0%, RTA = 62.86 ms|rta=62.862999ms;500.000000;1000.000000;0.000000 pl=0%;20;40;0" in /tmp/stdout.txt and 256 into /tmp/res.txt (weird?), with /tmp/stderr.txt remaining empty. Why does SIG{CHLD} affect whether I get "PING WARNING" or "PING OK"? I ran this test several times, so this isn't google.com being slow/fast issue. I also realize that the first result ("PING WARNING") is odd, since the RTA and packet loss look fine. -- We're just a Bunch Of Regular Guys, a collective group that's trying to understand and assimilate technology.
