First of all , How to see the users connected to my wifi ?
Something like this ,
Hostname , MAC Address


I would also like to know how to kick them off my wifi using terminal
Thanks in advance for y0ur h3lp

Have a look at your routers config. Mine has a page called 'Wireless MAC filter' to allow/deny access by mac address.

ACL is the way to go.

Only the machine that controls the network can kick other machines off of it. You need to be looking at your router's config page, there's nothing you can do on your linux terminal unless your router has ssh access or similar. Unless of course your linux machine IS the router, but in that case we need a LOT more info.

I've tried it already .
Whats that
Okay thanks for info

ACL's is a way to fine tune which users and groups can access files and directories on a nix system. Here is just one link that explains ACL's.

If MAC filtering didn't work for the OP, perhaps changing the wifi password will prevent those users from accessing it in the future.

I still can't figure out that how to see the users?

If you're using a wireless router then you can't see "users" at all, only MAC addresses. If you're using a Linux system as a WiFi router you still probably can't see "users" but only MAC addresses.

The only way I know of to do what the OP wants is through the router. It should have a browser interface, and you can see attached devices, configure wireless and wired settings, everything you need, from there, including deny users and kick them off. You can't do it through the terminal, unless you have an interface to the router there. The router is in charge of all that, and you should put both a strong admin password and a strong WPA password on it. If unknown, unauthorized people are on your network, you really need to get a grip on the router.

How to see the MAC Addresses? (Not of router)

If you're attached to the same router then you could use something like an nmap ping-sweep to then discover MAC addresses. However, you can't block them unless you log into the router as mentioned by others.

I don't recall the syntax, sorry, but if you read the man pages it ought to be fairly clear. There's a graphical front end called zenmap which may help also.

Something did occur that I forgot about before and that is you could probably run a WiFi sniffer, provided you can put your card in promiscouos mode, then I've a feeling I did read about a "magic packet" or something which can make a client disconnecyt from an access point -- I think it might involve MAC cloning or similar. However, if you do do any of this please remember to only do so on a network you own or have the full, writen, permision of the owner to do so.

I would of thought that you could run

or run it with grep to filter ip,s

then a ping flood to which ever ip not sure what that will do to rest of network tho
