  • netsh wlan add profile not importing passphrase

    - by sirlancelot
    I exported a wireless network connection profile from a Windows 7 machine correctly connected to a WiFi network with a WPA-TKIP passphrase. The exported xml file shows the correct settings and a keyMaterial node which I can only guess is the encrypted passphrase. When I take the xml to another Windows 7 computer and import it using netsh wlan add profile filename="WiFi.xml", it correctly adds the profile's SSID and encryption type, but a balloon pops up saying that I need to enter the passphrase. Is there a way to import the passphrase along with all other settings or am I missing something about adding profiles? Here is the exported xml with personal information removed: <?xml version="1.0"?> <WLANProfile xmlns="http://www.microsoft.com/networking/WLAN/profile/v1"> <name>[removed]</name> <SSIDConfig> <SSID> <hex>[removed]</hex> <name>[removed]</name> </SSID> <nonBroadcast>false</nonBroadcast> </SSIDConfig> <connectionType>ESS</connectionType> <connectionMode>auto</connectionMode> <autoSwitch>false</autoSwitch> <MSM> <security> <authEncryption> <authentication>WPAPSK</authentication> <encryption>TKIP</encryption> <useOneX>false</useOneX> </authEncryption> <sharedKey> <keyType>passPhrase</keyType> <protected>true</protected> <keyMaterial>[removed]</keyMaterial> </sharedKey> </security> </MSM> </WLANProfile> Any help or advice is appreciated. Thanks.

  • "macros have been disabled" message in Word 2007 but no macros

    - by Loftx
    Hi there, I open a .doc file in Word 2007 (sorry I am unable to supply the .doc) which pops up with a message above the document "Security warning: Macros have been disabled" but there are no macros shown in the macros listing and no functionality displayed in the VBScript editor. Why does Word think this document contains macros and how can I remove them to prevent the warning? Thanks, Tom

  • Can radius interact with pptp beyond authentication?

    - by Joe
    I've managed to setup pptp to use Radius authentication - making it much easier to manage users in an sql database than the default password file. However, ideally I'd like to be able to get the status of these users and disconnect/manage them as Radius allows - is this possible? If so, could you elaborate and point me in the right direction? All help is much appreciated! Edit I am personally using Debian and the standard aptitude packages for pptp and FreeRADIUS.

  • LUKS with LVM, mount is not persistent after reboot

    I have created a Logical vol and used luks to encrypt it. But while rebooting the server.

  • Netdom to restore machine secret

    - by icelava
    I have a number of virtual machines that have not been switched on for over a month, and some others which have been rolled back to an older state.

  • Assign fixed IP address via DHCP by DNS lookup

    - by Janoszen
    Preface I'm building a virtualization environment with Ubuntu 14.04 and LXC. I don't want to write my own template since the upgrade from 12.04 to 14.04 has shown that backwards compatibility is not guaranteed. Therefore I'm deploying my virtual machines via lxc-create, using the default Ubuntu template. The DNS for the servers is provided by Amazon Route 53, so no local DNS server is needed. I also use Puppet to configure my servers, so I want to keep the manual effort on the deployment minimal. Now, the default Ubuntu template assigns IP addresses via DHCP. Therefore, I need a local DHCP server to assign IP addresses to the nodes, so I can SSH into them and get Puppet running. Since Puppet requires a proper DNS setup, assigning temporary IP addresses is not an option, the client needs to get the right hostname and IP address from the start. Question What DHCP server do I use and how do I get it to assign the IP address based only on the host-name DHCP option by performing a DNS lookup on that very host name? What I've tried I tried to make it work using the ISC DHCP server, however, the manual clearly states: Please be aware that only the dhcp-client-identifier option and the hardware address can be used to match a host declaration, or the host-identifier option parameter for DHCPv6 servers. For example, it is not possible to match a host declaration to a host-name option. This is because the host-name option cannot be guaranteed to be unique for any given client, whereas both the hardware address and dhcp-client-identifier option are at least theoretically guaranteed to be unique to a given client. I also tried to create a class that matches the hostname like this: class "my-client-name" { match if option host-name = "my-client-name"; fixed-address my-client-name.my-domain.com; } Unfortunately the fixed-address option is not allowed in class statements. I can replace it with a 1-size pool, which works as expected: subnet 10.103.0.0 netmask 255.255.0.0 { option routers 10.103.1.1; class "my-client-name" { match if option host-name = "my-client-name"; } pool { allow members of "my-client-name"; range 10.103.1.2 10.103.1.2; } } However, this would require me to administer the IP addresses in two places (Amazon Route53 and the DHCP server), which I would prefer not to do. About security Since this is only used in the bootstrapping phase on an internal network and is then replaced by a static network configuration by Puppet, this shouldn't be an issue from a security standpoint. I am, however, aware that the virtual machine bootstraps with "ubuntu:ubuntu" credentials, which I intend to fix once this is running.

  • How to boot linux direct to application on console with no login

    - by amanda
    I have a need to start an application on bootup on the linux console and I do not have a need for any type of login or security. I do not need any ALT-F1,F2,etc virtual consoles but I would like to allow SSH access via the network port for debugging, loading, etc. The application is a SDL graphics program running with fbcon as the SDL_VIDEODRIVER if that matters. I'm currently using Fedora 10 and 12 but any distro that supports SDL using the fbcon framebuffer would be acceptable.

  • Why won't these permissions do what I wish?

    - by Chris B.
    I am trying to make my folder owned by "apache" and then chmod that folder so that only the owner and group can access it. I am trying to do this to keep visitors from executing user-uploaded files directly. Here are the commands I am using: chown -R apache uploads chmod -R 770 uploads Source: http://www.mysql-apache-php.com/fileupload-security.htm Instead it seems that although it is keeping visitors from seeing the files, it is not allowing apache to serve them. Do you have any ideas?

  • Execute a remote command on a Mac from Windows

    - by ripper234
    What's the easiest way to execute a single command on a Mac from a remote Windows machine, via batch? I'd like minimal pre-configuration (like SSH credentials) to exist on either machines, as I need to apply this on several Win/Mac pairs. The macs all have a common user/password (in fact, they are on the same domain), and I want to automate this as painlessly as possible.

  • Excluding executables in winsxs folder

    - by Yasser Sobhdel
    I am facing a big problem since there are many msbuild.exe files in .Netframework and winsxs folders and I don't know if it is required to set all of them as trusted in the antivirus. The path changes server to server and hence it makes life harder! If it matters to you, I am using Kaspersky endpoint security 10. When defining trusted application, as far as I know, you must point exactly to the executable with hard-coded path. Thanks

    Just installed it on my linux desktop, and I only want 1 or 2 files accessible to the outside world. Everything else should only be accessibly via http://localhost/ for various privacy/security reasons. It is just a test server, don't want just anybody accessing my large batch files. How would you go about allowing only certain select files access to the internet and making everything else available only via http://localhost/?

  • Simple way to make wired internet wireless without router

    - by Anriëtte Combrink
    Hi there Is there any device which you can plug into an Ethernet port and then have it broadcast the internet connection it receives through Ethernet wirelessly with a set password (maybe a serial number on device itself)? The problem is, I have a Wi-fi capable device, an iPhone and I want to use the wired internet connection in a hotel room, but the iPhone needs a Wi-fi signal. How can I accomplish this with a rather simplistic device. // EDIT: Can this be achieved with an Apple Airport Express?
