I want something a little more detailed. Thanks. > Don't underestimate the humble ping, in addition to confirming if you can access the specified host it can also be used to: - verify if there are DNS issues by pinging by both hostname and IP address. - verify if packet loss is an issue - estimate (crudely) bandwidth by varying packetsizes sent to hosts and calculating the difference between the round-trip times - check for possible routing problems by pinging each host on a problematic route - collect information about sporadic connectivity problems by running ping in the background and reviewing its output for any patterns - perform basic traffic tests by running multiple pings in the background and varying packet sizes and intervals Available now at a computer near you!
