Network Tools

Probing Host

netstat -untap
$ whowatch			# interactive  user and process monitoring tool
$ ss -ltpn			# socket status

DNS

  • wtfis / HN - Passive hostname, domain and IP lookup tool for non-robots
    • Only criticism is that it does use or need a bunch of accounts and API keys which probably makes the setup a bit tedious

perf host/host

also

iperf

You need to install iperf on both ends of the link you want to test, which in these examples are Studio and Uberpc. Then start iperf in server mode on one host, and run it in client mode on the other host. Note that on the client, you must name the server. This is the simplest way to run a test:

carla@studio:~$ iperf -s
terry@uberpc:~$ iperf -c studio
