Ping and Tracert
in [Linux Networking]

From: Geoff Lane on 13 Apr 2008 11:35 I was under the impression that Ping and Tracert were similar utilities with tracert giving a wee bit more information about the connection. Why is it then, if I ping bbc.co.uk I get response times of around 30ms whereas if I tracert the same address it appears to take much longer. Geoff Lane

There is no tracert in Linux. Why are you asking a windows question here? Are the windows lusers too stupid to answer it?

Why are you asking a windows question here? I was under the impression that the message header should have shown that I posted to two groups (uk.comp.home-networking) and the Followup-To: this group. I've checked it and it doesn't show this other group. As for my typing tracert, perhaps I should have said 'or traceroute in Linux > Are the windows lusers too stupid to answer it? Not really but Linux users are generally more techie :-) Geoff Lane
