| - | # TCP/IP Notes, Chapter 11 | ||
| - | ## Date: Mon Oct 12 2018 | ||
| - | Let's take a look at | ||
| - | |||
| - | **IPTRAF: Interactive colorful IP lan monitor** | ||
| - | |||
| - | ``sudo iptraf-ng`` | ||
| - | |||
| - | **IFTOP: Display bandwidth usage on an interface by host** | ||
| - | |||
| - | ``sudo iftop -i enp0s3`` | ||
| - | |||
| - | **tcpick: TCP stream sniffer and connection tracker** | ||
| - | |||
| - | ```bash | ||
| - | sudo tcpick -i enp0s3 | ||
| - | sudo tcpick -i enp0s3 -C -h -a | ||
| - | sudo tcpick -i enp0s3 -C -yP -h -a "port 80" | ||
| - | w3m http:// | ||
| - | w3m http:// | ||
| - | sudo tcpick -i enp0s3 -C -yP -h -a "port 443" | ||
| - | sudo tcpick -i enp0s3 -C -yP -h -a "port 22" | ||
| - | ``` | ||
| - | |||
| - | **NMAP: Network exploration tool and security / port scanner** | ||
| - | |||
| - | |||
| - | ```bash | ||
| - | sudo nmap 10.163.36.80 | ||
| - | sudo nmap -O 10.163.36.80 | ||
| - | ``` | ||
| - | |||
| - | Don't do this on a public network: | ||
| - | |||
| - | ```bash | ||
| - | ifconfig | ||
| - | sudo nmap -sP 10.163.36.0/ | ||
| - | ``` | ||
| - | |||
| - | **tcpdump: Dump traffic on a network** | ||
| - | |||
| - | ```bash | ||
| - | sudo tcpdump host 10.163.36.80 | ||
| - | to my machine machine | ||
| - | ``` | ||
| - | |||
| - | Exit out of host machine -- launch this from one machine on host machine, and | ||
| - | then on a separate machine, use w3m to visit the host machine: | ||
| - | |||
| - | ```bash | ||
| - | sudo tcpdump src 10.163.36.80 | ||
| - | sudo tcpdump dst 10.163.36.80 | ||
| - | sudo tcpdump port 80 -w http.pcap | ||
| - | ``` | ||
