Title:
iputils' ping seems to ignore the deadline (-w) setting
Status in “iputils” package in Ubuntu:
Fix Released
Bug description:
I came across this when I attempted to ping an unavailable host and
specified a deadline for my test. Spite the deadline setting, ping
didn't time out after specified time. However, it appears that -w is
ignored also for available hosts.
Examples:
[Unavailable host]
dc@dc:~$ time ping -c 3 -w 10 1.2.3.4
PING 1.2.3.4 (1.2.3.4) 56(84) bytes of data.

The older version of iputils' (20020927) ping behaves as expected.
