Chinese electronics company Huawei just made bold claims at MWC when its chairman, Richard Yu, said the Ascend D Quad is the world's fastest phone. Naming another milestone, Huawei has announced plans for the first 10-inch tablet powered by a quad-core processor.
Called the MediaPad10 FHD, the slate uses a similar 1.5GHz K3 CPU Huawei expects to place in the Ascend D Quad. Another alluring attribute you'll find in the MediaPad FHD is a 10-inch IPS LCD screen with a supersharp resolution of 1,920x1,200 pixels. Dolby Surround Sound audio processing will be onboard as well, along with an 8-megapixel main camera and 1.3-megapixel front-facing shooter.
Of course I thought the first 10-inch quad-core tablet was the Asus Transformer Prime. Truth be told, that's a 10.1-inch quad-core tablet, so perhaps Huawei is really splitting hairs here.
The tablet runs Android 4.0 Ice Cream Sandwich, too, and it will support 4G cellular data networks, either HSPA+ (21/42/84Mbps) or LTE. At 0.35 inch thick, the MediaPad10 FHD also appears to be just as svelte as its main Android rival, the Samsung Galaxy Tab 10.1.
While Huawei hasn't announced pricing for the MediaPad10 FHD, it says the powerful slate will hit the market globally in Q2 of 2012.
BSNL has announced it will be launching three Android tablets on March 1, with special data plans. Manufactured by Pantel, BSNL’s three tablets run on Android 2.3 Gingerbread, and aim to cater to both the low-end and mid-range segments of the markets, with prices ranging from Rs. 3,250 to Rs. 13,500. Pantel will also be looking to launch the tablets via MTNL in its markets.
The budget tablet - BSNL Penta T PAD IS 701R - bears a 7-inch resistive touchscreen with a 800x480 pixel resolution, a 1GHz processor, 256MB of RAM, 2GB of built-in storage with microSD expandability up to 32GB, Wi-Fi connectivity with 3G Dongle support, a 0.3MP camera, an HDMI port, and a 3000 mAh battery. It will be interesting to see the competition between the Aakash and this device.
Next up, is the BSNL Penta TPAD WS704C, priced at RS. 10,999. It runs on 1GHz processor with 512MB of RAM. Other specs include a 7-inch capacitive 800x480 pixel touchscreen, Wi-Fi and 3G connectivity with SIM card slot, has 4GB of built-in storage expandable via microSD up to 32GB, a 2MP rear camera, a 0.3MP front camera, Bluetooth connectivity, A-GPS support, an HDMI port and 1080p HD playback support.
The leader of the pack, the BSNL Penta TPAD WS802C, will be priced at Rs. 13,500. It will bear an 8-inch capacitive touchscreen, and run on a 1.2 GHz processor with 512MB of RAM. Other specs include 4GB of built-in storage with microSD expandability up to 32GB, a 2MP rear camera, a 0.3MP front camera, Bluetooth and A-GPS connectivity, as well as an HDMI port and support for 1080p HD playback.

7- Edit smb.conf: [global] #Domain name workgroup = MSHOME
# Sets the primary NetBIOS name of the Samba server netbios name = CLIENT-PDC
# Sets a descriptive string for the Samba server server string = %h
# The three passdb backends that are fully maintained (actively supported) by # the Samba Team are: smbpasswd (being obsoleted), tdbsam (a tdb-based binary file # format), and ldapsam (LDAP directory). # Of these, only the ldapsam backend stores both POSIX (UNIX) and Samba user # and group account information in a single repository. # The smbpasswd and tdbsam backends store only Samba user accounts. # It is recommended to use the tdbsam method for all simple systems. # Use ldapsam for larger and more complex networks. passdb backend = tdbsam
# Make domain logins query the Samba password db located on the samba server itself security = user
# File for user mapping username map = /etc/samba/smbusers
# lmhost: Uses a LAN Manager LMHOSTS file # hosts: Uses the standard name resolution methods of the Unix system # wins: Uses the WINS server # bcast: Uses a broadcast method name resolve order = wins bcast hosts
# Tells Samba to become the PDC domain logons = yes
# Makes the PDC act as the central store for names of all windows clients, # servers and printers preferred master = yes
# Samba will act as a WINS server wins support = yes
# Set CUPS for printing printcap name = CUPS printing = CUPS
# Default logon
#Drive letter under which the SAMBA share will appear in the Windows Explorer logon drive = H:
# you can specify a Windows batch script that is executed as soon as a # Windows workstation logs in # This option specifies a Windows .BAT or .CMD file with lines # ending in carriage-return/line feed that will be executed on the # client after a user has logged on to the domain. Each logon # script should be stored # at the base of a share entitled [netlogin] logon script = login.bat
# The base directory that supports the profiles logon path = \\client-pdc\profile\%U
# Useradd scripts add user script = /usr/sbin/useradd -m %u delete user script = /usr/sbin/userdel -r %u add group script = /usr/sbin/groupadd %g delete group script = /usr/sbin/groupdel %g add user to group script = /usr/sbin/usermod -G %g %u add machine script = /usr/sbin/useradd -s /bin/false/ -d /var/lib/nobody %u idmap uid = 15000-20000 idmap gid = 15000-20000
# sync smb passwords with linux passwords passwd program = /usr/bin/passwd %u
# This option works like a Unix chat passwd chat = *Enter\snew\sUNIX\spassword:* %n\n *Retype\snew\sUNIX\spassword:* %n\n .
# Sends debug logs of the password-change process # to the log files with a level of 100 passwd chat debug = yes
# Samba updates the standard Unix password db, # when a user changes his encrypted password unix password sync = yes
# set the loglevel log level = 3
#Defines the users home directiory [homes] comment = Home

# Does'nt allow others to browse the contents of the directory browsable = no
[printers] comment = All Printers path = /var/spool/samba printable = yes guest ok = yes browsable = no
# Make sure permissions are 755 # Contains scripts that the windows clients may use when they log into the domain [netlogon] comment = Network Logon Service path = /home/samba/netlogon admin users = Administrator

8- Create the directories for domain logons and profiles: mkdir /home/samba mkdir /home/samba/netlogon mkdir /home/samba/profiles mkdir /var/spool/samba chmod 777 /var/spool/samba/ chown -R root:users /home/samba/ chmod -R 771 /home/samba
9- restart Samba: /etc/init.d/samba restart
10- Edit /etc/nsswitch.conf. Change the line:
hosts: files dns
hosts: files wins dns
11- Add the root user to the SAMBA password database. The root user (alias: Administrator) will be our domain administrator. This account is needed to add new computers to the SAMBA domain.
smbpasswd -a root
12- Create the file /etc/samba/smbusers and add the line by executing:
echo "root = Administrator" > /etc/samba/smbusers
13- Now test if the setup is correct:
smbclient -L localhost -U%
The output should look similar to this:
Domain=[MSHOME] OS=[Unix] Server=[Samba 3.0.24]
Sharename Type Comment --------- ---- ------- print$ Disk Printer Drivers Domain=[MSHOME] OS=[Unix] Server=[Samba 3.0.24]
Server Comment --------- ------- CLIENT-PDC client-PDC server (Samba, Ubuntu)
17- At the end of the file /etc/samba/smb.conf add the following lines:
[allusers] comment = All Users path = /home/shares/allusers valid users = @users force group = users create mask = 0660 directory mask = 0771 writable = yes
18- restart Samba
19- acl Support:
With a Samba server, only the owner of a file or folder may change its permissions. When modifying the ACLs of files via the ACL dialog, you will need to login as the user who owns those files in order to make the changes. For files that will be managed by multiple administrators, change the owner of those files to Administrator or some other common user. To modify permissions of these files via the ACL dialog, you will need to login as this user.
20- Configure Windows XP clients
You should start the process for Windows XP clients by a complete Windows Update. After the release of Service Pack 2, Microsoft Windows way of dealing with profile has changed a bit. You will need to start by login into your Windows XP client locally as Administrator and execute :
then, you must navigate to :
Local Computer Policy / Computer Configuration / Administrative Templates / System / User Profiles
and change the setting of the key 'Do not check for user ownership of Roaming Profile Folders' from 'Not Configured' to 'Enable'. If that key is not present, you should try visiting Windows Update again. Then you can use 'File / Exit'. This is needed because WinXP actually checks ACL Permission in your profile file system (which isn't really that easy to develop under *NIX). Once this is completed, you can procede as for Windows 2000.
Alternatively, you can add the following registry key:
Step 3: Edit /etc/samba/smb.conf Notes: Change the NETBIOS name parameter to be correct for the server. Make a backup copy of the original file!!! ) Make the edits. The configuration shown is the bare minimum and doesn't share anything. Code: [global] workgroup = CONNECTA security = ads netbios name =COPPELIUS001 realm = CONNECTA.LOCAL preferred master = yes encrypt passwords = yes log file = /var/log/samba/%m winbind separator = + password server = mercury.connecta.local idmap uid = 600-20000 idmap gid = 600-20000 winbind enum users = yes winbind enum groups = yes winbind use default domain = yes winbind nested groups = yes guest account = nobody template shell = /bin/bash nt acl support = true
2) Test the configuration with the "testparm" command Code: testparm Step 4: Edit /etc/nsswitch.conf to look like the example below Code: passwd: compat winbind group: compat winbind shadow: compat hosts: files dns wins networks: files protocols: db files services: db files ethers: db files rpc: db files netgroup: nis
Step 5: Modify the PAM settings
1) /etc/pam.d/common-account should contain only the following lines Code: account sufficient pam_winbind.so account required pam_unix.so
2) /etc/pam.d/common-auth should contain only the following lines Code: auth sufficient pam_winbind.so auth required pam_unix.so nullok_secure use_first_pass
3) Modify the /etc/pam.d/common-password file, so the max parameter is set to 50, similar to the one shown below Code: password required pam_unix.so nullok obscure min=4 max=50 md5
4) Make sure the /etc/pam.d/common-session file contains the following line Code: session required pam_mkhomedir.so umask=0022 skel=/etc/skel Step 6: Make a directory to hold domain user home directories Note: Use the value you put in the WORKGROUP tag of the /etc/samba/smb.conf file
Code (if you want to use WORKGROUP): mkdir /home/DOMAIN
Step 7: Initialize Kerberos
1) Code: kinit domain_admin_account@CONNECTA.LOCAL Next check to be sure you got a ticket from the domain controller It's possible that With ADMINISTRATOR you have problem, then you must change ADMINSITRATOR's password on Active-Directory!!
2)KLIST Shows the current ticket(s): Code: klist
Step 8: Join the system to the set Computer name in /etc/hosts to fully qualified name (example: aspirin.CONNECTA.LOCAL)
Code: net ads join -U administrator@CONNECTA.LOCAL
Error: kinit(v5): Clock skew too great while getting initial => The time at server and client are not same, and must be synchronized.
Step 9: Restart Samba-related Services (Or reboot the server)
[newtest] path = /data available = yes browsable = yes read only = no public = yes writable = yes security mask = 0777 force security mode = 0 directory security mask = 0777 force directory security mode = 0 nt acl support = yes store dos attributes = yes dos filemode = yes
Step 11-1: Share permission management in WINDOWS
1. Launch the NT4 Server Manager and click on the Samba server you want to administer. From the menu select Computer, then click on Shared Directories. 2. Click on the share that you wish to manage and click the Properties tab, then click the Permissions tab. Now you can add or change access control settings as you wish.
from Control Panel -> Administrative Tools run Computer Management:
1. After launching the MMC with the Computer Management snap-in,click the menu item Action and select Connect to another computer.If you are not logged onto a domain you will be prompted to enter a domain login user identifier and a password. This will authenticate you to the domain. If you are already logged in with administrative privilege, this step is not offered. 2. If the Samba server is not shown in the Select Computer box, type in the name of the target Samba server in the field Name:. Now click the on [+] next to System Tools, then on the [+] next to Shared Folders in the left panel. 3. In the right panel, double-click on the share on which you wish to set access control permissions. Then click the tab Share Permissions. It is now possible to add access control entities to the shared folder. Remember to set what type of access (full control, change, read) you wish to assign for each entry
Warning: Be careful. If you take away all permissions from the Everyone user without removing this user, effectively no user will be able to access the share. This is a result of what is known as ACL precedence. Everyone with no access means that MaryK who is part of the group Everyone will have no access even if she is given explicit full control access.
Step 11-2: Share permission management in UBUNTU
setfacl: This utility sets Access Control Lists (ACLs) of files and directories. -R : Recursive -m : Modify -x : Delete
