Hi

/usr/bin/ping does not return the correct return code on ping failure.
See example below, the .8 host does not exist, .9 does exist:

$ ping 56 1 192.168.20.9 > /dev/null ; echo $?
0
$ ping 56 1 192.168.20.8 > /dev/null ; echo $?
0

I checked Linux and Windows versions of ping and they work correctly.
$ ping -c 1 192.168.20.8 > /dev/null ; echo $?
1
$ ping -c 1 192.168.20.9 > /dev/null ; echo $?
0

$ /cygdrive/c/WINDOWS/system32/ping.exe -n 1 \
> 192.168.20.8 > /dev/null ; echo $?
1
$ /cygdrive/c/WINDOWS/system32/ping.exe -n 1 \
> 192.168.20.9 > /dev/null ; echo $?
0

I didn't look into the ping source, so no diff ...
I just aliased ping with the windows version as a workaround.

Kind regards,

Tom Van Looy
