See hostname of users using Ad-Hoc connection

shadyabhi · 2011-03-10 23:27:01

I use the following script to create ad-hoc connection.

#!/bin/bash

sudo iwconfig wlan0 mode ad-hoc
sudo iwconfig wlan0 essid shadyabhi
sudo iwconfig wlan0 key 0123456789
sudo ifconfig wlan0 192.168.1.1
sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
sudo su -c "echo 1 > /proc/sys/net/ipv4/ip_forward"
sudo iptables -t mangle -A PREROUTING -j TTL --ttl-inc 1
sudo /etc/rc.d/dnsmasq restart

Someone please guide my on how can I find out the hostname of the the machines using my ad-hoc?

If your hosts aren't registering with an internal DNS server, then you won't be able to resolve them.

@fukawi2

See, I cant find out of what all have used my ad-hoc by checking the file /var/lib/misc/dnsmasq.leases

But, how do I know, who all are "currently" using it?

ping their addresses?
Run tcpdump and/or wireshark to see what traffic is passing through?

tcpdump -lnn -i wlan0
