Hello guys,yesterday I tried to "sniff" some network packets so as to find out passwords from my Laptop and from others devices in my network,
At first from my laptop works perfectly,I just had to select the correct interface(eth0,wlan0,any).After that I was about to try do the same thing so as to catch the password from my phone! But it didn't worked! I choose at first wlan0,after that eth0(because I connect my laptop with ethernet cable as well due to disconnections) and at the end I tried the "any" interface.Nothing!
I did a little research and I came accross the "monitor mode".I see what it is and where it is used so I searched how to enable it in my laptop so as I could do my job!
I opened a terminal and typed in:
Code:
airmon-ng check kill
I read that I should kill all processes before enabling monitor mode and if I do not,then I get an message in the terminal
I get this output:
Code:
Killing these processes:
PID Name
786 wpa_supplicant
798 dhclient
2201 avahi-daemon-ch
Then my wifi isn't working and I could connect to the internet only through ethernet!
Then type in the terminal
Code:
airmon-ng start wlan0
The output I get after typing that command is:
Code:
PHY Interface Driver Chipset
phy0 wlan0 rtl8723be Realtek Semiconductor Co., Ltd. RTL8723BE PCIe Wireless Network Adapter
(mac80211 monitor mode vif enabled for [phy0]wlan0 on [phy0]wlan0mon)
(mac80211 station mode vif disabled for [phy0]wlan0)
Internet stills working only when laptop is connected with ethernet cable.
What's more in Wireshark,in the interface list the "wlan0" is renamed in "wlan0mon".
No "Monitor Mode" checkbox appears in Wireshark.
I have again Internet access through wifi only when I type in the terminal:
Code:
service network-manager start
But the wlan0mon interface in Wireshark doesn't see any packets even if I am using my wifi with my laptop and my phone!
At the end,if I type in terminal:
Code:
airmon-ng stop wlan0mon
I get output:
Code:
PHY Interface Driver Chipset
phy0 wlan0mon rtl8723be Realtek Semiconductor Co., Ltd. RTL8723BE PCIe Wireless Network Adapter
You are trying to stop a device that isn't in monitor mode.
Doing so is a terrible idea, if you really want to do it then you
need to type 'iw wlan0mon del' yourself since it is a terrible idea.
Most likely you want to remove an interface called wlan[0-9]mon
If you feel you have reached this warning in error,
please report it.
My wireless network card is: Realtek Semiconductor Co., Ltd. RTL8723BE PCIe Wireless Network Adapter
I am currently running Kali Linux 2 Rolling Edition
Please HELP! What should I do?? Thanks
