I tried the following command unsuccessfully
sdiff <(ping www.nato.int) <(ping www.reuters.com)

Running Ubuntu 9.04. I can ping hosts all day long but when I try to ping a host that doesn't exist, it instead sends pings to 8.15.7.100, which turns in to packet loss, but I'd prefer it if it told me the host cannot be found.

If you are trying to use PING to resolve a name, I'd rather use the nslookup command instead.

Is there a ping replacement that will display the system's date/time in addition to the round trip time and sequence number? I would prefer a tool that runs on Linux, but if there is a cli tool I can run on Windows that would be good too.
