How to detect ips using nmap?

Question

I am currently working on demonstrating Man in middle Attack foe which I am using my phone as a Victim and my PC running ubuntu 14.04LTS as attacker. I am using nmap to ping my phone to check if its online...

nmap -e wlan0 -sn 172.16.95.198

But don't know how even when phones on same network I get a result ..

Note: Host seems down. If it is really up, but blocking our ping probes, try -Pn
Nmap done: 1 IP address (0 hosts up) scanned in 1.54 seconds

So I tried with -Pn as well but output remains the same (host seems down) which is not the case. The phone is up and running... Please help I am new to networking what am I possibly doing wrong???

The parameter -Pn is only for skip the host discovery. Probably Your phone has not any port listening. If you want to check if your phone has listening port: In the phone:

netstat -lntu

If your phone has not any listening port, try to install one service and scan again.

This happens with any other device instead of phone too. – Saurabh Thakur Feb 27 '15 at 03:39
Yes, It is because the devices are dropping the ICMP packets – sinkmanu Feb 27 '15 at 06:10
So what commands do you suggest in nmap so that i can detect ip's of various devices around on the same local network... – Saurabh Thakur Feb 27 '15 at 08:36

For example, you can use the parameter -PR (ARP Ping). Here you can see more methods to do a host discovery. http://nmap.org/book/man-host-discovery.html – sinkmanu Feb 27 '15 at 16:25
