Remember your network might be in a different range than the example. Enter the following to discover all the devices on your network. We will be using it in this exercise to make a basic Network Discovery. Nmap was introduced as a port scanner, but it’s far outgrown that title at this point. One of which is the fact that it is extremely effective. This popularity can be attributed to many factors. Additionally I need the -b flag to tell ping that I really do want to ping a broadcast address.Nmap is by far one of the most popular tools in the world of information security. Here I first used ifconfig to see what the IP address of eth0 is and then I ping it. TX packets:52031936 errors:0 dropped:0 overruns:0 carrier:0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 $ ifconfig eth0Įth0 Link encap:Ethernet HWaddr b8:ae:ed:a4:08:97
You can do the same with IPv4, but it involves an additional step to look up the broadcast address for the segment. The address ff02::1 is an anycast address targeting all hosts on the link.įinally %eth0 is the notation appended to link-local IPv6 addresses in order to indicate which interface to be using. The -c2 flag means it will send only two pings before terminating.
Without that it would be slowed down by trying to perform reverse DNS on link-local addresses, which is not going to work anyway. The -n flag means no reverse DNS will be performed. The simplest way to ping all the hosts on a LAN is with IPv6: ping6 -nc2 ff02::1%eth0
#PING SWEEP MANUAL#
Here is the ubuntu manual to use fping with different options. The network and broadcast addresses will be excluded. Specify the netmask or start/end in the targets Generate a target list from a supplied IP netmask, or a startingĪnd ending IP. Pinging a target will be made, not including the first try. This is the number of times an attempt at Nmap done: 256 IP addresses (12 hosts up) scanned in 4.46 secondsįping is another command to ping all ip in LAN.
#PING SWEEP FOR ANDROID#
Nmap scan report for android (10.0.0.196) Nmap scan report for android (10.0.0.188) Nmap scan report for android (10.0.0.181) Nmap scan report for android (10.0.0.148) Nmap scan report for terrance-ubuntu (10.0.0.100) You can scan other IP address ranges like 192.168.0.1 - 192.168.1.254 by typing in the following: nmap -sP 192.168.0.1/23Ī typical scan might return something like the following: nmap -sP 10.0.0.1/24
The above command will scan all IP addresses starting at 192.168.1.1 through 192.168.1.254 and show you all IPs that responded.
Then you can check your entire network for all connected IP addresses by typing in the following: nmap -sP 192.168.1.1/24
#PING SWEEP INSTALL#
You can install an application called nmap.
