Create NFS Datastore For ESX in WIn Server 2K8 R2

                             Services for NFS, is used to integrate Unix and Linux hosts with Windows Servers, allowing those hosts to share files. It can connect the Windows Server to an NFS share (could be another server or a NAS) as a client, but Services for NFS can also make the Windows Server into an NFS server. In other words, it can turn your Windows Server into a NFS Network Attached Storage NAS device.

Add the Services for NFS

            1. From your Windows host, run Server Manager.

2. Click on Roles and then on Add Role.

3. Click to add the File Services Role.

4. Under Role Services click to add Services for Network File System. Click Next and Install.

Crete Folder and Set NFS Permissions

                         Create a new Windows folder and share it using NFS (which has different permissions than Windows). Right-click on that folder and click on Properties. You'll see a new tab called NFS Sharing.

1. Click on the NFS Share Permissions button

2. Checked to allow all machines Read-Write and root access.

3. Checked to "enable unmapped user access." From there, click OK and OK.

4. Give everyone full control in the NTFS permissions.

Mount Shared folder into the vSphere

In the vSphere Client, go to the ESXi host you want to connect and to the Configuration tab, then to Storage.

1. Click to Add Storage and add a Network File System.
2. Enter the Server name (via IP or DNS name), NFS Share name and a new name that you specify for the new NFS datastore.

Clear The Terminal Command History

                               By default, up to the last 500 command lines a user types in the terminal window are saved into a hidden .bash_history file. The previously typed commands can be readily accessed by using the up and down arrow keys.

Viewing the complete terminal command

               To view the complete history of commands typed in the terminal "for the logged in user" 

        Open a terminal window and type   history

Clear the terminal command line history:

1. Login with the user account whose terminal history you plan to clear
2. Open a terminal window and type history -c

Samba Server Configuration In Ubuntu 14.04 LTS-Secured Samba Sharing Server

                                Samba is an Open Source/Free Software suite that provides seamless file and print services to SMB/CIFS clients. Samba is freely available, unlike other SMB/CIFS implementations, and allows for interoperability between Linux/Unix servers and Windows-based clients.

                               SMB, which stands for Server Message Block, is a protocol for sharing files, printers, serial ports, and communications abstractions such as named pipes and mailslots between computer

 

Secured Samba Sharing Server

Ubuntu SAMBA Server

1. Install the samba

apt-get install samba samba-common python-glade2 system-config-samba

2. Create a group “smbgrp” & user “jagan” to access the samba server with proper authentication

root@server1:~#addgroup smbgrp

root@server1:~#adduser jagan -G smbgrp

root@server1:~# smbpasswd -a jagan

New SMB password:

Retype new SMB password:

Added user jagan

3. Create the folder viz secured in the /samba folder & give permissions like this

root@server1:~#mkdir -p /var/samba/secured

root@server1:~#cd /var/samba

root@server1:~#chmod -R 0770 secured/

4. Edit the configuration file as : (Add at the end of the file )

vi /etc/samba/smb.conf

[secured]
path = /var/samba/secured
valid users = @smbgrp
guest ok = no
writable = yes
browsable = yes

5. Restart the Samba services to enable the new configuration:  

service smbd restart

service nmbd restart

Client Windows Machine

                         Now at windows machine check the folder now with the proper credentials.You will again face the issue of permissions to give write permission to the user jagan do

Modified the Permissions in Samba Server

cd /var/samba/

            chown -R jagan:smbgrp secured/

Samba Server Configuration in Ubuntu 14.04 LTS-Anonymous Samba Sharing

                                Samba is an Open Source/Free Software suite that provides seamless file and print services to SMB/CIFS clients. Samba is freely available, unlike other SMB/CIFS implementations, and allows for interoperability between Linux/Unix servers and Windows-based clients.

                               SMB, which stands for Server Message Block, is a protocol for sharing files, printers, serial ports, and communications abstractions such as named pipes and mailslots between computer

 
Anonymous Samba Sharing

Ubuntu SAMBA Server

1. Install the samba with the anonymous sharing

apt-get install samba samba-common python-glade2 system-config-samba

2. Configure samba edit the file /etc/samba/smb.cnf

3. Before making changes take backup of original file mv /etc/samba/smb.cnf /etc/samba/smb.cnf.bak

4. Edit /etc/samba/smb.cnf

vi /etc/samba/smb.cnf

[global]
workgroup = WORKGROUP
server string = Samba Server %v
netbios name = ubuntu
security = user
map to guest = bad user
dns proxy = no
#============================ Share Definitions ==============================
[Anonymous]
path = /var/samba/anonymous
browsable =yes
writable = yes
guest ok = yes

5. Create directory for Sharing Location

mkdir -p /var/samba/anonymous

6. Restart the Samba services to enable the new configuration:  

service smbd restart

service nmbd restart

Client Windows Machine

                         From windows machine just browse the folder & try to create a text file, but you will get an error of permission denied.

                           In Run :- \\SAMBA Server IP

Modified the Permissions in Samba Server

1. Check the permission for the shared folder.

root@server1:~# ls -l /var/samba/anonymous
        total 4

drwxr-xr-x 2 root root 4096 May 27 18:17 anonymous

2. Allow anonymous user give the permissions as follows;

root@server1:~# cd /var/samba/

root@server1:/var/samba# chmod -R 0755 anonymous/

root@server1:# chown -R nobody:nogroup anonymous/

root@server1:/var/samba# ls -l

total 4

drwx-xr-x 2 nobody nogroup root 4096 May 27 18:17 anonymous

Additional Notes:- Normally In smb.conf we have append the following details: Eg:-

[share]
   comment = Ubuntu File Server Share
   path = /var/samba/jagan
   browsable = yes
   guest ok = yes
   read only = no
   create mask = 0755

*******************************************************************************************************

comment: a short description of the share. Adjust to fit your needs.

path: the path to the directory to share.

browsable: enables Windows clients to browse the shared directory using Windows Explorer.

guest ok: allows clients to connect to the share without supplying a password.

read only: determines if the share is read only.Write privileges are allowed only when the value is no, as is seen in this example. If the value is yes, then access to the share is read only.

create mask: determines the permissions new files will have when created.

Setting Up My Family For Windows Phone

Setting Up My Family For Windows Phone For Nokia Lumia My Family Setup Problem
                   When I try to download any app from marketplace it says "you have to set-up my family".
Reason :- The Master Account (Microsoft ID registered with Phone) Sync with Phone is under 18
Solution 1 :- Open up your Microsoft account (which you use with your phone), go to personal settings, and turn your birth date to make you appear 18 or elder.
But sometimes DOB modification  is not possible, so follow the second solution
Solution 2 :-  Set up My Family so a child can download apps and games
1. On your computer, go to My Family (http://www.windowsphone.com/en-IN/family) on the Windows  Phone website.
2.Sign in using the parent's Microsoft account.(http://www.windowsphone.com/en-in/how-to/wp8/accounts-and-billing/what-is-a-microsoft-account).If the parent doesn't have a Microsoft account, you'll have the chance to create one.
3. On the My Family setup page, click Get started. (If you've added a child to My Family before or have set up a family using another Microsoft service, you may not see Getting started and can just click Add a kid.)
4. To add a child to My Family, click Go. On the sign-in page, Enter the Microsoft account the child uses to sign in to their phone. Now the child can download apps from the Windows Phone Store.

Installation Of .NET Framework 3.5 On Windows 8

                              Windows 8 does not include .NET 3.5 (include .NET 2.0 and 3.0) by default. But if the user is upgrading from Windows 7 to Windows 8, .NET Framework 3.5 is fully enabled. By the below mentioned ways, we can install NET 3.5 on Windows 8 or 8.1 and also in Windows Server 2012.

Method :- 1 Installing the .NET Framework 3.5 on Demand

                                  If an app requires the .NET Framework 3.5, but doesn't find that version enabled on your computer, it displays the following message box, either during installation, or when you run the app for the first time.This option requires an Internet connection.
 

 

Method :- 2 Installation Of .NET Framework 3.5 in Control Panel
                               You can also enable the .NET Framework 3.5 yourself through Control Panel. In Control Panel, choose Programs and Features, choose Turn Windows features on or off, and then select the .NET Framework 3.5 (includes .NET 2.0 and 3.0) check box. This option requires an Internet connection.

Method :- 3 Installation Of.NET Framework 3.5 on Windows 8 in Offline Mode

1. Insert Windows 8 DVD or mount ISO image.
                        The source of this feature can be found in folder E:\sources\sxs.(In this case E: the user’s drive letter on which the user has loaded Windows 8 Media.)

2. Once the ISO is mounted and we have correctly identified the drive path we need to enable the .NET Framework. This can be done through command line using the dism.exe command or alternatively through the Windows GUI-As same as in the method:-2
Open CMD.EXE with Administrative Privileges.Run the following command
Dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:E:\sources\sxs /LimitAccess

Method :- 4 Download the package of .NET for Windows 8 and install the same
