With netkit-base-0.10-31, code was removed which caused termination when the "-c <N>" packets were sent. This causes problems if you are using ping from a script to monitor a downed host. Also, the documentation includes the phrasing "Stop after sending (and receiving) [...]". If the intention is that (unlike other systems) it only count *RECEIVED* packets, why is that in parenthesis. The patch I will be submitting shortly changes the man page and causes the old behavior of terminating after N packets are sent (and responses waited for). EFFECT: Without this fix, netsaint (and other monitoring software I'm sure) fills up your process table with pings. Sean
*** Bug 4082 has been marked as a duplicate of this bug. *** On the alpha, netkit-base-0.10-29 had the unaligned trap bug, but after installing netkit-base-0.10-31 (which fixed the unaligned trap) ping -c does not work properly. Specifically, "ping -c x unreachable-host" causes ping to start a stream of pings (as seen by tcpdump) that does not stop after "x" pings. Pinging a host that is reachable with the -c option works properly. In this case, I use ping -c to bring up a demand ppp link so I have reverted to the 0.10-29 kit shipped with 6.0 Alpha. --Larry ------- Additional Comments From dkl@redhat.com 07/22/99 11:33 ------- I was able to replicate this problem on an alpha and intel machine in our test lab with this update. I tried to ping www.redhat.com and ftp.redhat.com which are set up to reject ping requests so therefore I get the unreachable errors. It seems the -c <some num> option is ignored when used and a host is unreachable. This is being assigned to a developer for further review. ------- Additional Comments From jbj@redhat.com 07/23/99 04:09 ------- *** Bug 4169 has been marked as a duplicate of this bug. *** Here is the transcript of my session notice that I installed the original rpm ran my test then ran the new rpm and it failed!

I have an original 6.0 install which has a different date and size from the original. The dates on the original install is: 14804 Apr 7 ping and the new one is: 17652 Jul 6 ping This effectivly breaks ping. Which is vital to my script. Meanwhile I have moved the older version onto this computer and I have changed my script to refernece the old version of ping. If someone could please look into why this is happening. Oh the platform is Intel. Thanks Jim Brown ------- Additional Comments From dkl@redhat.com 07/22/99 11:10 ------- I could not get this update to fail on a test lab machine running standard 6.0 with updates.
Fixed in netkit-base-0.10-33.
