This is an old revision of the document!
Let's take a look at
IPTRAF: Interactive colorful IP lan monitor
IFTOP: Display bandwidth usage on an interface by host
`sudo iftop -i enp0s3`
tcpick: TCP stream sniffer and connection tracker
sudo tcpick -i enp0s3 sudo tcpick -i enp0s3 -C -h -a sudo tcpick -i enp0s3 -C -yP -h -a "port 80" w3m http://10.163.36.69/~sean/ w3m http://10.163.36.69/ 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
sudo nmap 10.163.36.80 # List open ports sudo nmap -O 10.163.36.80 # List open ports, enable OS detection
Don't do this on a public network:
ifconfig # identify network ID and Mask sudo nmap -sP 10.163.36.0/24 # map network or subnet
tcpdump: Dump traffic on a network
sudo tcpdump host 10.163.36.80 # see all packets leaving and coming 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:
sudo tcpdump src 10.163.36.80 # see packets leaving my machine sudo tcpdump dst 10.163.36.80 # see packets coming to my machine sudo tcpdump port 80 -w http.pcap # save all http traffic to http.pcap file
