From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; Boeing Kit; .NET CLR 1.1.4322) Description of problem: The -f (flood) option to ping does not work in FedoraCore2, the pings work, but it's not flooding at all. It works fine in RedHat9, and replacing the FC2 ping binary with redhat9's binary also works fine under FC2. Version-Release number of selected component (if applicable): iputils-20020927-13 How reproducible: Always Steps to Reproduce: 1. On a redhat9 system, ping flood a system (ping -f -n xxx.xxx.xxx.xxx) for a few seconds, then control-C out. Examine the number of paets transmitted vs. the number of seconds, typical PCs might send 5000 packets/sec or so. 2. repeat the test using a FC2 system, and see how many are sent Actual Results: It's pretty obvious that the FC2 ping binary is ignoring the -f option totally. Additional info:
PING 192.168.1.16 (192.168.1.16) 56(84) bytes of data. RHEL3 with base iputils --- 192.168.1.16 ping statistics --- 244 packets transmitted, 244 received, 0% packet loss, time 4502ms rtt min/avg/max/mdev = 0.131/0.350/0.821/0.129 ms, pipe 2, ipg/ewma 18.528/0.424 ms Fedora Core 2 with iputils-20020124-16 --- 192.168.1.16 ping statistics --- 399 packets transmitted, 399 received, 0% packet loss, time 5989ms rtt min/avg/max/mdev = 0.128/0.383/0.809/0.170 ms, pipe 2, ipg/ewma 15.047/0.426 ms You can see that results are quite worse on FC2 but I would say that is's because of our regular net traffic.
Please reopen. Only 60 packets/second (RHEL3) isn't a flood, it's a trickle. I get 5000 packets/second using RH9, whose -f option works.
(more data from here - redhat9 => redhat9) 26519 packets transmitted, 26519 received, 0% packet loss, time 5878ms rtt min/avg/max/mdev = 0.153/0.159/0.532/0.014 ms, ipg/ewma 0.221/0.155 ms
Fedora Core 2 is now maintained by the Fedora Legacy project for security updates only. If this problem is a security issue, please reopen and reassign to the Fedora Legacy product. If it is not a security issue and hasn't been resolved in the current FC3 updates or in the FC4 test release, reopen and change the version to match.
please reopen for fc3, it's broken there (still).

Not sure whether any RedHat version ever had a decent floodping. Ime, every single version I ever tried was horribly slow, including RH7 and RH8 systems. The debian version is quite a bit faster: # time ping -f -c 1000 9.152.251.1 PING 9.152.251.1 (9.152.251.1): 56 data bytes . --- 9.152.251.1 ping statistics --- 1000 packets transmitted, 1000 packets received, 0% packet loss round-trip min/avg/max = 0.1/0.1/2.8 ms real 0m0.328s user 0m0.008s sys 0m0.016s I guess you can take the debian package, compare the sources and figure where your problem is.
Thanks for a tip with debian package. A small fix seems to resolve this issue, please try the latest iputils-20020927-27 package
