• Getting Xbox Live via a wired network with my laptop that has internet access wirelessly

  - by Alex Franco

  I'm running the latest version (as of yesterday anyways) of Ubuntu Desktop 64bit, but installed on my laptop if it makes a difference. I had Windows 7 preinstalled when i bought it and it worked fine with the wireless from my house and bridging the connection with a LAN to my xbox for Live. Now with Ubuntu I tried the same setup, but I'm unfamiliar with Ubuntu so I didn't get far. Best I got so far is wireless internet on my laptop and a wired connection to the xbox that continually connects and disconnects. Heres my network settings. if theres fields not included its because theyre empty on mine or theyre my MAC address or network password Wireless Network 1 settings: Connect Automatically: Checked. Available to all Users: Checked Wireless: SSID: Franco's Mode: Infrastructure MTU: Automatic IPv4 Settings: Method: Automatic (DHCP) IPv6 Settings: Method: Automatic Wired Network 1: Connect Automatically: Checked Available to all Users: Checked Wired: MTU: Automatic IPv4 Settings: Method: Automatic (DHCP) IPv6 Settings: Method: Automatic Any help would be greatly appreciated. EDIT: 6:26pm It seems to be staying connected now. Doing the Network test on my xbox it pickups the network, but cannot detect any PC. Restarting the Xbox, however, leaves my computer unable to connect bringing up the Wire Network disconnected 'blip' every minute or so again. Before I had restarted the Xbox it said "Connected 100 MB/s". Now it only says "connecting". I did have my computer and xbox on in this Wired Network Disconnected blip cycle for a long period of time so it may have finally connected, just without the ability to detect my laptop. I left for 2 hours or so in the middle of typing up the original question. I finished posting this when i got back and then tried to mess with it a bit again, in case youre wondering why i didnt include this before... I've said too much. Forgive my long-winded fingers :p

• Can't connect to or see my wifi ssid

  - by ant

  Today I installed ubuntu 12.04 on my laptop. I am unable to see my home SSID or even connect to it. I've tried to connect as a hidden SSID but I always get prompted for authorization although my key is correct. I'm in in Europe but my laptop is from US. I'm not sure if that is relevant. I've read around this site and saw something that has to do with setting the channel above 11. I'm not sure I did that correctly I did this : How to use Wi-Fi channels above 11? Did't help. I'm able to connect with cable but not via wifi either windows or linux. Other devices in my home can connect without any issues, even the kindle. Here is the screenshot from my router : Here is some additional info : lspci | grep -i network 08:00.0 Network controller: Qualcomm Atheros AR9285 Wireless Network Adapter (PCI-Express) (rev 01) lspci -nnk | grep -A2 0280 08:00.0 Network controller [0280]: Qualcomm Atheros AR9285 Wireless Network Adapter (PCI-Express) [168c:002b] (rev 01) Subsystem: Hewlett-Packard Company U98Z062.10 802.11bgn Wireless Half-size Mini PCIe Card [103c:303f] Kernel driver in use: ath9k m-tool NetworkManager Tool State: connected (global) Device: wlan0 ---------------------------------------------------------------- Type: 802.11 WiFi Driver: ath9k State: disconnected Default: no HW Address: 90:4C:E5:38:79:0D Capabilities: Wireless Properties WEP Encryption: yes WPA Encryption: yes WPA2 Encryption: yes I'm not sure what to do next.

• I don't know how to connect to the internet

  - by Michiel

  I'm having some trouble finding an answer to my problem. I have a dell desktop (studio hybrid) and i have windows vista on it. The internet on windows vista works great, no problem. But now i downloaded Ubuntu 11.10 and I'm having problems. I can't find how to connect to my wireless network, when i click the network icon, it shows a list of things but I can only click 'enable wireless network' or something like that and 'edit connections'. But in this list it also says ( in a grey collor and i can't click it ) : 'No wireless connection, device not ready (firmware missing)" Or something like that. Now i tried several things i read on the internet (using my vista OS cause i can't use ubuntu for the internet, which is really enoying). But none of them helped me. I would like someone to tell me what my problem is or what information I have to give you to get an answer. So tell me if i have to edit a connection, or tell me how i have to get the wireless connection to work and to repair the 'firmware missing problem'. I hope someone can/is willing to help me. Bye

• Update Manager got stuck (but not frozen) while installing downloaded updates. What should I do?

  - by WarriorIng64

  I have just gotten my Ubuntu 12.04 LTS desktop computer reassembled after a trip back home and connected it to my parent's wireless Internet connection. The connection seems quite shaky (disconnects half the time, likely an ongoing issue with the wireless card I have installed), and it struggled to download updates because of the constant interruptions. Eventually, it managed to download the updated packages and started installing them. I got up and left it to do its work. When I came back, I saw it was still having trouble staying connected to the wireless (no surprise there), but then I noticed that it seemed like Update Manager had stopped making progress on the installation. I opened the Details pane to see what it was last doing: My guess was that the installation script for flashplugin-installer couldn't complete the download until I stabilized the Internet connection. I hooked my Ubuntu laptop up to my desktop via Ethernet and shared its wireless connection using this guide, and as I am typing this now from my desktop you can see that the connection issue was successfully worked around. However, even with a stable connection established, Update Manager seems "stuck" at its current position and won't go any further. It's not totally frozen, but I can't do anything beyond open/close the Details pane as the Cancel button is grayed out. I know it can cause big problems if updates are stopped during installation, but I'm at a loss as to how this situation should be handled. I'm sure it should finish normally if I can just find a way to restart Update Manager, but the question is how this should be approached. How can I safely get my updates to finish installing?

• Broadcom 4313 doesn't work following 12.04 upgrade

  - by Lucas

  I have an hp G62-228Ca laptop with a BCM4313 previously running Ubuntu 11.10. I ran the 12.04 upgrade last night without much thought. Following the upgrade and mandatory reboot, the wireless card no longer shows up in the network manager, the first time I've had any kind of issues with wireless under Ubuntu. I've done much Googling on the issue but so far I haven't found a permanent solution. Mucking around with some packages though (I've installed five different ones or so), I've managed to devise a workaround that I must run every time I boot the laptop. I have to remove the Broadcom STA driver and reinstall it. Inspiration taken from here: WiFi does not work, Broadcom STA Wireless driver does not work on a BCM4313 After the second modprobe command, the wireless reappears in the network manager and ten seconds after that I'm back on the wifi. If anyone can provide some advice on how to fix this permanently I will be extremely grateful. I'd rather not roll back to 11.10 or reinstall, but I will if I need to. Just let me know if you need the output from any terminal commands. Thanks in advance!

• 13.10 - Weird WiFi connection problems - WMP300N - Broadcom BCM4321

  - by user1898041

  Just installed 13.10 on my desktop and I really like it. After having problems with getting the wifi to work, I installed it connected to the internet with an ethernet cable and added in the 3rd party software and updates as per the installation procedure. After installation was completed, I saw the wifi icon in the upper right hand corner, but it was not seeing any wifi networks. Some Googling brought me to use the 'Additional Drivers' application. It found the WMP300N Broadcom BDM4321 based pci wifi card and installed the proprietary Broadcom STA wireless driver, which may have been installed before. I'm not sure. Here is the weird part: when I start my system, wifi seems to be in some sort of suspended state where the system sees that the card exists but the card will not detect any wifi networks. It will work after booting once I 'Additional Drivers' application and then start FireFox. I know it seems weird, but this is the process I've got down to get the card to recognize wifi networks. After those applications are open for a few seconds, the card starts to function like normal (although maintaining the wifi connection is problem but most likely a seperate issue). The reason this is a problem is because this is supposed to just be a headless box managed through SSH. Here are the readouts from the common network diagnosis programs BEFORE I open 'Additional Drivers' and 'FireFox'. All commands were done with sudo. lspci 00:00.0 Host bridge: Intel Corporation 82G35 Express DRAM Controller (rev 03) 00:01.0 PCI bridge: Intel Corporation 82G35 Express PCI Express Root Port (rev 03) 00:1a.0 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #4 (rev 02) 00:1a.1 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #5 (rev 02) 00:1a.2 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #6 (rev 02) 00:1a.7 USB controller: Intel Corporation 82801I (ICH9 Family) USB2 EHCI Controller #2 (rev 02) 00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 02) 00:1c.0 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 1 (rev 02) 00:1c.4 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 5 (rev 02) 00:1c.5 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 6 (rev 02) 00:1d.0 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #1 (rev 02) 00:1d.1 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #2 (rev 02) 00:1d.2 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #3 (rev 02) 00:1d.7 USB controller: Intel Corporation 82801I (ICH9 Family) USB2 EHCI Controller #1 (rev 02) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev 92) 00:1f.0 ISA bridge: Intel Corporation 82801IR (ICH9R) LPC Interface Controller (rev 02) 00:1f.2 SATA controller: Intel Corporation 82801IR/IO/IH (ICH9R/DO/DH) 6 port SATA Controller [AHCI mode] (rev 02) 00:1f.3 SMBus: Intel Corporation 82801I (ICH9 Family) SMBus Controller (rev 02) 01:00.0 VGA compatible controller: NVIDIA Corporation GT216 [GeForce GT 220] (rev a2) 01:00.1 Audio device: NVIDIA Corporation High Definition Audio Controller (rev a1) 02:00.0 Ethernet controller: Qualcomm Atheros Attansic L1 Gigabit Ethernet (rev b0) 03:00.0 IDE interface: JMicron Technology Corp.

• Setting up a VPN connection to Amazon VPC - routing

  - by Keeno

  I am having some real issues setting up a VPN between out office and AWS VPC. The "tunnels" appear to be up, however I don't know if they are configured correctly. The device I am using is a Netgear VPN Firewall - FVS336GV2 If you see in the attached config downloaded from VPC (#3 Tunnel Interface Configuration), it gives me some "inside" addresses for the tunnel. When setting up the IPsec tunnels do I use the inside tunnel IP's (e.g. 169.254.254.2/30) or do I use my internal network subnet (10.1.1.0/24) I have tried both, when I tried the local network (10.1.1.x) the tracert stops at the router. When I tried with the "inside" ips, the tracert to the amazon VPC (10.0.0.x) goes out over the internet. this all leads me to the next question, for this router, how do I set up stage #4, the static next hop? What are these seemingly random "inside" addresses and where did amazon generate them from? 169.254.254.x seems odd? With a device like this, is the VPN behind the firewall? I have tweaked any IP addresses below so that they are not "real". I am fully aware, this is probably badly worded. Please if there is any further info/screenshots that will help, let me know.

We recommend configuring DPD on your endpoint as follows: - DPD Interval : 10 - DPD Retries : 3 IPSec ESP (Encapsulating Security Payload) inserts additional headers to transmit packets. These headers require additional space, which reduces the amount of space available to transmit application data. To limit the impact of this behavior, we recommend the following configuration on your Customer Gateway: - TCP MSS Adjustment : 1387 bytes - Clear Don't Fragment Bit : enabled - Fragmentation : Before encryption #3: Tunnel Interface Configuration Your Customer Gateway must be configured with a tunnel interface that is associated with the IPSec tunnel. All traffic transmitted to the tunnel interface is encrypted and transmitted to the Virtual Private Gateway. The Customer Gateway and Virtual Private Gateway each have two addresses that relate to this IPSec tunnel. Each contains an outside address, upon which encrypted traffic is exchanged. Each also contain an inside address associated with the tunnel interface. The Customer Gateway outside IP address was provided when the Customer Gateway was created. Changing the IP address requires the creation of a new Customer Gateway. The Customer Gateway inside IP address should be configured on your tunnel interface. Outside IP Addresses: - Customer Gateway : 217.33.22.33 - Virtual Private Gateway : 87.222.33.42 Inside IP Addresses - Customer Gateway : 169.254.254.2/30 - Virtual Private Gateway : 169.254.254.1/30 Configure your tunnel to fragment at the optimal size: - Tunnel interface MTU : 1436 bytes #4: Static Routing Configuration: To route traffic between your internal network and your VPC, you will need a static route added to your router.

The VGW will then send traffic towards your internal network over the tunnels. EDIT #1 After writing this post, I continued to fiddle and something started to work, just not very reliably. The local IPs to use when setting up the tunnels where indeed my network subnets. Which further confuses me over what these "inside" IP addresses are for. The problem is, results are not consistent what so ever. I can "sometimes" ping, I can "sometimes" RDP using the VPN. Sometimes, Tunnel 1 or Tunnel 2 can be up or down. When I came back into work today, Tunnel 1 was down, so I deleted it and re-created it from scratch. Now I cant ping anything, but Amazon AND the router are telling me tunnel 1/2 are fine. I guess the router/vpn hardware I have just isnt up to the job..... EDIT #2 Now Tunnel 1 is up, Tunnel 2 is down (I didn't change any settings) and I can ping/rdp again. EDIT #3 Screenshot of route table that the router has built up. Current state (tunnel 1 still up and going string, 2 is still down and wont re-connect)

• How to relink user folders in Windows 7

  - by Jonathan

  The short story: Win7 lost track of my user folders location (desktop, my documents, my pictures etc...). They now reside on a different partition. How can I relink these folders? The long story: The way I partition my drives is: C: - SSD drive for Windows and Program Files D: - A large regular hard drive for all my user data The first thing I do after a fresh Win7 install is move my user folders to D:, by right clicking on these folders under C:\users\username\, choosing the Location tab and clicking on Move. I've just completed encryption of D: using TrueCrypt. It shows a lot of warnings before the encryption process, but (hrrmm...) it does not mention the fact that after encryption the data is located on a new drive letter, say E: This broke Win7's links to my special user folders. How can I relink these folders?

• Setting up Kerberos SSO in Windows 2008 network

  - by Arturs Licis

  We recently introduced Kerberos (SPNEGO) Single Sign-on in our web-portal, and tested it on a Windows network with Windows 2003 domain controller. Now, trying to test it on Windows 2008 R2 controlled network, SSO just doesn't work due to defective tokens. Up to the moment I was pretty sure that there's something wrong about environment and that were NTLM tokens. We double checked IE settings etc, but nothing helped. Then we checked the following settings for both users (logged on a client test-machine, and the one used as a Service Principal): This account supports Kerberos AES 128 bit encryption. This account supports Kerberos AES 256 bit encryption. .. and error message changed to ' GSSException: Failure unspecified at GSS-API level (Mechanism level: Encryption type AES256CTS mode with HMAC SHA1-96 is not supported/enabled) It makes me think that Internet Explorer receives Kerberos tokens at all times, and there's just some configuration missing, or it was ktpass.exe to be incorrectly executed. Here's how ktpass.exe was invoked: C:ktpass /out portal1.keytab /mapuser USER /princ HTTP/[email protected] /pass *

• How to Make Your Verizon FIOS Router 1000% More Secure

  - by The Geek

  If you’ve just switched to Verizon FIOS and they’ve installed the new router in your house, there’s just one problem: it’s set to use lousy WEP encryption by default, instead of the much more secure WPA2. Here’s how to fix it. The problem with WEP encryption is that it can be cracked really easily—a skilled hacker can do it in a few minutes, and even an unskilled geek can do it in just a little more time with the right tools. Once they’ve done that, they can leech off your internet connection and do anything they want—including illegal stuff coming from your network. Note: if you are using an old Nintendo DS connected to the internet, they usually only support WEP encryption, so you may not want to do this Latest Features How-To Geek ETC The Complete List of iPad Tips, Tricks, and Tutorials The 50 Best Registry Hacks that Make Windows Better The How-To Geek Holiday Gift Guide (Geeky Stuff We Like) LCD?

• Anonymous exposes sensitive bank emails

  - by martin.abrahams

  As expected for quite a while, emails purporting to reveal alleged naughtiness at a major bank have been released today. A bank spokesman says "We are confident that his extravagant assertions are untrue". The BBC report concludes…  “Firms are increasingly concerned about the prospect of disgruntled staff taking caches of sensitive e-mails with them when they leave, said Rami Habal, of security firm Proofpoint. "You can't do anything about people copying the content," he said. But firms can put measures in place, such as revoking encryption keys, which means stolen e-mails become unreadable, he added.” Actually, there is something you can do to guard against copying. While traditional encryption lets authorised recipients make unprotected copies long before you revoke the keys, Oracle IRM provides encryption AND guards against unprotected copies being made. Recipients can be authorised to save protected copies, and cut-and-paste within the scope of a protected workflow or email thread – but can be prevented from saving unprotected copies or pasting to unprotected files and emails.  The IRM audit trail would also help track down attempts to open the protected emails and documents by unauthorised individuals within or beyond your perimeter.

• “No Network Devices Available” for BCM43241(SDIO) after fresh install of 13.10

  - by 200gaga

  I have a laptop vaio duo 13 which has a broadcom 43241 wireless card. My problem is similar to this one Broadcom Wi-Fi Adapter not recognized . I tried to install the driver brcmfmac(SDIO) here http://wireless.kernel.org/en/users/Drivers/brcm80211 and copied the nvram to /lib/firmware/brcm as the page tells, but this didn't work. Most questions I searched are about br43 such as How to Install Broadcom Wireless Drivers (BCM43xx) . I tried part of solution like unblock all in rfkill, put an # in front of blacklist bcm43xx, but none worked. I didn't uninstall or install any drivers such as b43-installer, b43legacy-installer, bcmwl-kernel-source (only tried b43-fwcutter) because they are not compatible with bcm43241. Above is all information I can provide for help. Thanks.

• Internet Connection Problems

  - by Confused One

  I just installed Ubuntu 11.04 onto a laptop. There is no list of automatic connections when I click on the internet connection symbol. Enable Wireless was unchecked, so I checked it. However, it continues saying "wireless is disabled." Soft is blocked, and when I tried rfkill unblock wifi it told me that the device was not ready. I tried to counter this with what I found on this thread but nothing worked. I have tried manually entering my Wireless information, but this does not help. Is there a solution?

• Is the Lenovo Ideapad Z570 fully compatible with 12.04?

  - by umpirsky

  I'm looking for some notebook that will run on Ubuntu perfectly. I like LENOVO IdeaPad Z570, but I'm not sure how it will perform on Ubuntu. I heard people are complaining about wireless problems. Here is full configuraion: Processor Intel Core i5 2430M 2.4GHz - 3.0GHz Chipset Intel HM65 Express Memory 4GB DDR3 1333MHz Graphics NVIDIA GeForce GT 520M 1GB HDD 750GB SATA II Wireless 802.11b/g/n, Bluetooth 2.1 Network adapter Ethernet LAN 10/100Mbps Ports VGA, HDMI, 3x USB 2.0, eSATA Does anyone have experience with this model? Any problems noted? I heard there is a test suite, how can I install it? Maybe I can boot live CD and try it myself before buying it. But, unfortunately, sometimes something works on live CD, but not when you install it. I guess critical components here are graphics and wireless. Any feedback would be appreciated.

• Oh no! My padding's invalid!

  - by Simon Cooper

  Recently, I've been doing some work involving cryptography, and encountered the standard .NET CryptographicException: 'Padding is invalid and cannot be removed.' Searching on StackOverflow produces 57 questions concerning this exception; it's a very common problem encountered. So I decided to have a closer look. To test this, I created a simple project that decrypts and encrypts a byte array: // create some random data byte[] data = new byte[100]; new Random().NextBytes(data); // use the Rijndael symmetric algorithm RijndaelManaged rij = new RijndaelManaged(); byte[] encrypted; // encrypt the data using a CryptoStream using (var encryptor = rij.CreateEncryptor()) using (MemoryStream encryptedStream = new MemoryStream()) using (CryptoStream crypto = new CryptoStream( encryptedStream, encryptor, CryptoStreamMode.Write)) { crypto.Write(data, 0, data.Length); encrypted = encryptedStream.ToArray(); } byte[] decrypted; // and decrypt it again using (var decryptor = rij.CreateDecryptor()) using (CryptoStream crypto = new CryptoStream( new MemoryStream(encrypted), decryptor, CryptoStreamMode.Read)) { byte[] decrypted = new byte[data.Length]; crypto.Read(decrypted, 0, decrypted.Length); } Sure enough, I got exactly the same CryptographicException when trying to decrypt the data even in this simple example. Well, I'm obviously missing something, if I can't even get this single method right! What does the exception message actually mean? What am I missing? Well, after playing around a bit, I discovered the problem was fixed by changing the encryption step to this: // encrypt the data using a CryptoStream using (var encryptor = rij.CreateEncryptor()) using (MemoryStream encryptedStream = new MemoryStream()) { using (CryptoStream crypto = new CryptoStream( encryptedStream, encryptor, CryptoStreamMode.Write)) { crypto.Write(data, 0, data.Length); } encrypted = encryptedStream.ToArray(); } Aaaah, so that's what the problem was. The CryptoStream wasn't flushing all it's data to the MemoryStream before it was being read, and closing the stream causes it to flush everything to the backing stream. But why does this cause an error in padding? Cryptographic padding All symmetric encryption algorithms (of which Rijndael is one) operates on fixed block sizes. For Rijndael, the default block size is 16 bytes. This means the input needs to be a multiple of 16 bytes long. If it isn't, then the input is padded to 16 bytes using one of the padding modes. This is only done to the final block of data to be encrypted. CryptoStream has a special method to flush this final block of data - FlushFinalBlock. Calling Stream.Flush() does not flush the final block, as you might expect. Only by closing the stream or explicitly calling FlushFinalBlock is the final block, with any padding, encrypted and written to the backing stream. Without this call, the encrypted data is 16 bytes shorter than it should be. If this final block wasn't written, then the decryption gets to the final 16 bytes of the encrypted data and tries to decrypt it as the final block with padding. The end bytes don't match the padding scheme it's been told to use, therefore it throws an exception stating what is wrong - what the decryptor expects to be padding actually isn't, and so can't be removed from the stream. So, as well as closing the stream before reading the result, an alternative fix to my encryption code is the following: // encrypt the data using a CryptoStream using (var encryptor = rij.CreateEncryptor()) using (MemoryStream encryptedStream = new MemoryStream()) using (CryptoStream crypto = new CryptoStream( encryptedStream, encryptor, CryptoStreamMode.Write)) { crypto.Write(data, 0, data.Length); // explicitly flush the final block of data crypto.FlushFinalBlock(); encrypted = encryptedStream.ToArray(); } Conclusion So, if your padding is invalid, make sure that you close or call FlushFinalBlock on any CryptoStream performing encryption before you access the encrypted data. Flush isn't enough. Only then will the final block be present in the encrypted data, allowing it to be decrypted successfully.

I have tried the manual setup options setting up the pop3 incoming server on port 995 with SSL encryption and the smtp out going server on both ports 25 and 587 with TTL encryption. It acts like it is connected, but it just keeps wanting to refresh and never shows anything in the inbox.

• Disallow user from decrypting the startup disk

  - by Blacklight Shining

  When you enable FileVault's full-disk encryption, it asks for the password of each account on the system to allow every user to decrypt the disk. You can simply choose not to have a user enter their password, and they will not be able to decrypt the disk. However, if you create an account after enabling disk encryption, the user is automatically allowed to decrypt the disk. How do I disallow a user from decrypting the startup disk?

• Are Time Machine backups secure?

  - by Leandro Ardissone

  I have my Time Machine backups on an external disk (WD My Passport with no hardware encryption) and I'm worried if the data stored on the disk is safe in case somebody steals it and connect it to any Mac/PC. Does any Mac can browse the Time Machine backups? Or are they encrypted in any way? If no, is there a way to improve security of the backups, should I buy a hardware encryption based HD? Thanks.

• Should I obscure primary key values?

  - by Scott

  I'm building a web application where the front end is a highly-specialized search engine. Searching is handled at the main URL, and the user is passed off to a sub-directory when they click on a search result for a more detailed display. This hand-off is being done as a GET request with the primary key being passed in the query string. I seem to recall reading somewhere that exposing primary keys to the user was not a good idea, so I decided to implement reversible encryption. I'm starting to wonder if I'm just being paranoid. The reversible encryption (base64) is probably easily broken by anybody who cares to try, makes the URLs very ugly, and also longer than they otherwise would be. Should I just drop the encryption and send my primary keys in the clear?
