Network monitoring software

[rip]

I'm looking for a FREE program to monitor who's stealing my wireless internet conection.

I haven't got it encrypted it because i have several people I live with that share the connection and we were having lots of connection problems.

I'm not overly concerned about it as I live in a small city, but I'd like to know if/when people are leaching my connection.

Thanks

wat router do u have?

[FreakinPrince]

why don't you secure it and give the secure password to the people that you are allowing them to use? its really simple as that


a friend of mine comes over and want to use the wirless i just give him the password to connect to the router and bam he is online

you can always change it after if they are no longer living with you or whatever

if you look under the DHCP button on your router, there should be a list that liste all computer name with specific ip address

maybe there is a name that you don't know and it could give itself out which you might figure out who?

Or you can leave it unsecure, but lock it to the MAC address's of only people you want.

But you are 100% liable for the content the freeloader is surfing. like if they are kiddie porn addicts, you goto jail.

If you want to lock everyone out, just set WEP + MAC address block.

If you want to have FUN with people leeching, just check your DHCP log on your router and see who has been requesting addresses and ping the IP and see if they are still on line.

Then do what you will with them.

You might as well not set any encryption if you're using wep. Don't kid yourself that it will last longer than 30 seconds with easily available script kiddie tools. And mac spoofing can be done using winxp natively.

WPA-PSK using tkip is the bare mininum. WPA2-PSK with AES is the ideal.

Some type of D-link.

Like I said above I've tried this, but for whatever reason not everyone that I was sharing my connection with could always connect even with the provided password.

How do I do this?

I really have no clue what any of the above means, but if you could dumb it down for me I'm sure it would be useful.

Yea, I beleive the WPA--PSK explaination is a little techie.

I would lock it to MAC addresses, even tho they are spoofable, its hard to find the correct one to spoof it to. Plus if someone has that much time on their hands they will get in anyways.


WPA2 <- Encryption and Requires you to give people a password, and for those people to have compatable hardware, good method, but not everyone can do it.

WEP-128 <- Most compatable protection, requires password but can be broken into.

If you have any encryption or form of protection, it makes it illegal to use without permission, and its better than leaving it open.

MAC Protection <- Each network card / wireless card has a unique MAC address, it is located on the card itself, or you can do an ipconfig /all in a command prompt to display it. Physical Address = MAC address.

In your routers config pages / manual, it should explain how to setup the MAC filtering.

If you provide the Exact model # off of the DLink device, I can set you up with the more proper instructions.

[codetrap]

Run the Dlink setup wizard on the CD. Choose the encryption WPA. Change your SSID to something like "Private-NoAccess". That makes it very clear that your network is private.

Choose a passphrase.. not a password. Make it alphanumeric, and at least 10 characters long

Then, on your PC, just use your standard windows way of connecting. When it finds your network, it will ask you for that passphrase. Put it in, and voila, it should connect.

A little light reading on the topic..

ethereal/wireshark 24/7 so you can see sites they visited too, maybe steal their password too

This wont work.

Since the router itself is the device that receives that packets and forwards them to the internet, running any program like this on your computer would do nothing.

Unless the router has a "monitor" port, their is no free way to do this via software only.

[nos_efx]

For your everyday user, WEP + Mac address filtering is going to be sufficient.

In reeality, if they want in they are going to get in.

[nos_efx]

Please explain step by step how your buddies are connecting? This shouldnt be a difficult problem to fix.

We were using WEP encryption with a password. I'm going to look into it agiain next week and If I still can't get it working I'll come asking for your guys help. You guys seem to know your shit and I know that this shouldn't be a hard fix.

THanks for the input.

There are ways to do this besides using a monitoring/SPAN port, such as arp poisoning. Pretty easy to set up and run but it might increase latency slightly. And seeing as this is a privately owned network, there should be no legal situations.

there is a program that is very nice for home networks it is called network magic. It will tell you if anyone is leeching your system and you can kick them off.

It is trialware but the first month or so is free and should be enough to find any offenders.
