NMAP and SSH
NMAP
- Find my ip: ifconfig
- Scan networks: nmap <ip>
- Find live hosts: nmap -sP 192.168.0.*
- Scan specific port: nmap -p 80 server2.tecmint.com
- Scan a single ip address: nmap 192.168.1.1
- Scan a host name: nmap server1.cyberciti.biz
- Scan a host name with more info : nmap -v server1.cyberciti.biz
- Scan with disabled port scan: nmap -sn 192.168.2.1/24
- Read and scan from txt file: nmap -iL /tmp/test.txt
- Create the txt file to read from: cat > /tmp/test.txt
SSH
- Connect: ssh collie.stanford.edu
- Log-in: ssh jhawkins@collie.stanford.edu
