[ NNSquad ] Re: Catalog of Measurement Tools
A few tools on the top of my head:
* netcat, to quickly test tcp connections, combined with pv  to test the throughput. this is useful to test throughput on different ports, but requires netcat (or at least a TCP socket that accepts what you throw at it) on the other end * netrw will do the same, but all in one tool * bing can test bandwidth using only ICMP (ping) requests
Of course, I guess I should mention those de-facto standard utilities:
* traceroute (AKA tracert under windows), the NANOG version also has extra interesting features * ping * nmap * mtr (traceroute merged with ping, on steroids) * wireshark (ex-ethereal) and tcpdump, to inspect traffic
I'm not providing URLs for those because they're fairly common.
I'm probably missing a few, especially for injecting arbitrary packets, for example.
