Locating other machines

• check network files like /etc/hosts or resolv.conf

• in linux you can run nmcli dev show

• use bach one liners to look for other hosts

  • for i in {1..255}; do (ping -c 1 192.168.1.${i} | grep "bytes from" &); done

• A bash one liner for ports

  • for i in {1..65535}; do (echo > /dev/tcp/192.168.1.1/$i) >/dev/null 2>&1 && echo $i is open; done
