LAN Manager authentication level

Some smb shares on linux server works with Windows 7 and some has authentication issue.  All works with windows XP.  I had to set to "send LM and NTLM response" under local security policy for the client computer for it to connect to the linux file server.  Why do I have to set manually, why isn't this default on windows 7, and what would prompt some linux server to work and some to not? LM and NTLM version 1 are extremely insecure methods of password hashing. All versions of Windows and server include backward compatibility for older versions of Windows and applications. As we see newer operating systems (like Win 7) they will default to a more secure method to help protect the password hashes. Therefore, when using Windows 7 you will likely need to force it to use this backward compatibility if you are connecting to something that doesn't support the newer methods like NTLM v2 or Kerberos. As for your specific situation; are the Linux servers running different dist

What Is the uses of VPN?

A VPN is a way to connect to the internet through an encrypted connection. When you access a website, upload data to an app or check your email, the VPN encrypts all your communications and sends them to a server run by the VPN provider, which then sends them on to their destination. That is useful for preserving your privacy when you don't trust the network you're on, whether it's an internet service provider or a Wi-Fi connection at an airport or coffee shop. You can also use a VPN to connect to a corporate network for work purposes. Many companies use this method to limit access to their internal networks to employees with VPN usernames and passwords and to encrypt their connections to work machines. How Does VPN Work? A VPN encrypts all the data you send from your computer across the internet, shapes it into specially formatted packets of data and sends them to the VPN server. The server has digital keys it can use to decrypt the data, but anybody else without these ke

how to Troubleshooting NTLM

This section provides help for diagnosing and resolving any issues that might arise when configuring NTLM.Alfresco supports NTLM v2 protocol, which is more secure than NTLM v1 protocol. However, NTLM v2 cannot be used with pass-through authentication. You will have to switch to NTLM v1 if you want to use pass-through authentication, where Alfresco passes the log on request to an Active Directory or other server to validate the login credentials. roubleshooting This problem is most likely caused by enhanced security in Windows 7, Vista and Windows 2008. Previous versions of Windows (XP) would fall back to NTLM v1, if NTLM v2 failed. On Windows 7 clients, navigate to Control Panel > Administrative Tools > Local Security Policy. In the left pane, navigate to Security Settings > Local Policies > Security Options. In the right pane, find Network Security: LAN Manager authentication level. By default, the value of Network Security: LAN Manager authentication level is set

Hide a Security Camera in Plain Sight

Security cameras are used by homeowners to monitor children, look out for intruders and generally keep a watch over a home. Many homeowners seek ways to hide these cameras, but fail miserably. By using a tissue box and a little ingenuity, you can hide a camera that is placed out in the open and no one will be the wiser. Step 1 Remove all the tissues from the tissue box through the top and using a utility knife place a small pinhole in the side of the box. Step 2 Place the security camera into the box, making sure that its lens is pointed out the hole in the side. Step 3 Place the tissues back into the box, hiding the camera. Step 4 Attach the video output of the wireless receiver to the video input of the monitor using the composite video cable. Step 5 Turn on all devices, including the camera by sticking your hand down into the tissue box and flipping the switch. Step 6 Synchronize the frequency of the camera to that of the wireless receiver by tuning the receiver until Also read : 

How to Connecting Network Cameras to Windows 10 Devices

Network cameras, which are Internet Protocol-based cameras that transmit video data over a local area network (LAN), are becoming increasingly prevalent – especially in surveillance and security scenarios. Windows now allows users to associate network cameras to their PC, enabling photo capture and streaming of video in camera applications. Currently Windows only supports ONVIF Profile S compliant cameras*, which are standards-compliant network cameras optimized for real-time streaming video capture. Note: The features discussed in this article are available with Windows 10, Insider Build 18995. Windows provides support for discovery, pairing, configuration and streaming via WinRT APIs. To discover network cameras connected to the local subnet, create a DeviceWatcher class and follow the instructions specified in this document, connect to remote cameras. Also find :   windows lan
