running>
>Category: <user amd64 system>
>Environment:
System : OpenBSD 5.9
Details : OpenBSD 5.9 (GENERIC.MP) #8: Tue Sep 27 07:59:42 CEST
2016

GENERIC.MP
Architecture: OpenBSD.amd64
Machine : amd64
>Description:
if you are doing ping to one host and some one else use the
traceroute command, then traceroute command no timeout all the hops.
>How-To-Repeat:
$ ping 10.39.62.49

in another session run the command :
$ traceroute -I openbsd.org
traceroute to powerbasic.com (209.217.33.58), 64 hops max, 60 byte packets
1 192.168.134.91 (192.168.134.91) 2.928 ms 0.517 ms 0.346 ms
2 RNMCIC3 (192.168.131.49) 1.132 ms 1.095 ms 1.065 ms
then traceroute stop and doesn´t show more lines or hops.If you broke the
command ping (Ctrl C) in the first session, or ping is not running,
traceroute go on.

The lines 4 and 5 show * (timeouts) this time .It is ok.
>Fix:
In $OpenBSD: *traceroute.c,v 1.95* 2014/03/24 11:11:49 this problem
doesn't exist.
