Importing contacts from another phone onto a Nokia phone

I had a Sony Ericson phone, before I had to switch to a Nokia phone (Nokia X2). The initial problem was to export all the contacts from Sony Ericson phone onto Nokia phone. This is the solution that worked.

Step 1: Export the contacts from old phone onto computer

For Sony Ericson, I used ‘My phone explorer’.  Goto > Contacts > Right click on the contacts Window > Export/Import > Export entire phone book. Save the file into *.vcf format.

For other phone, find utilities to export all the contacts in either *.vcf, or *.csv format or some other standard format.

Step 2 : Import contacts onto MS Outlook Express

MS Outlook > Tools > Address Book.

In the Address Book, File > Import > Business card > Open the *.vcf file.

Step 3 : Import the MS Outlook Express contacts onto Nokia phone.

Install Nokia Ovi Suite application.

Connect the phone and select ‘Nokia Ovi Suite’ when prompted on the phone.

Start Nokia Ovi Suite application.

Detect the phone via Nokia Ovi Suite application.

Goto Nokia Ovi Suite Application > Sync > Sync options > Contacts > Sync with contacts application > Microsoft Outlook express > Shared contacts > Press OK.

Nokia Ovi Suite Application > Sync > Sync Now > Contacts… (Check the details.. If the contacts are not copied completely, retry till all the contacts are imported.)

How to “remote desktop” into a Windows machine from Linux?

“rdesktop” is a Linux utility equivalent of Windows Remote Desktop (mstsc.exe).

• Download the source package from http://www.rdesktop.org/
• Extract the source package.
• ./configure
• make
• make install
• rdesktop hostname

If you want full screen, “rdesktop -f hostname”.  You can exit full screen using CTRL-ALT-ENTER.

How to overcome a hang in remote PC while using Remote Desktop?

This can be done with the help of two commands: “query session” and “reset session”.

 

c:\> query session

SESSIONNAME       USERNAME                 ID  STATE   TYPE        DEVICE
console           userA                                   0              Active  wdcon
rdp-tcp                                                     65536            Listen  rdpwd
rdp-tcp#28        Administrator             1                 Active  rdpwd
rdp-tcp#27        userB                              2                 Active  rdpwd

 

;Note down the session ID. Now execute…

c:\> reset session 2 /v /server

;This logs out user from session 2.

 

Now, t o execute these two commands, you can remote login to the system using another power user or you can telnet to the system (if telnet available).

 

How to mount Windows shares in Linux?

Method 1:

$ mkdir /mnt/winshare

$ mount -t cifs //nt_machine_name_or_ip_address/shared_folder_name -o username=user_name_here,password=pass_word_here /mnt/winshare

$ cd /mnt/winshare

$ ls

(If you need to write to this directory, change the settings in Windows system to include read/write permission)

 

Method 2 (persistant):

$ mkdir /mnt/winshare

$ vim /etc/fstab

Add the following line to the file…

//nt_machine_name_or_ip_address/shared_folder_name           /mnt/win                cifs    username=user_name_here,password=password_here 0 0

How to change Linux runlevel at boot time?

Different runlevels under Fedora core:

0	Halt
1	Single-User mode
2	Multi-user mode console logins only (without networking)
3	Multi-User mode, console logins only
4	Not used/User-definable
5	Multi-User mode, with display manager as well as console logins (X11)
6	Reboot

When the Linux kernel boots, the init program reads the /etc/inittab file to determine the runlevel. The behavior of each run level is specified using a configuration file.

Modifying runlevel using Grub at boot time:

Select the kernel you want to load

Press ‘e’ to edit …

In the line that looks similar to “blah blah blah nomodeset rghb quiet”, append the number of runlevel you desire after a space… like “blah blah blah nomodeset rghb quiet 3”

Press ‘b’ to boot.

This change is only applicable to the current boot.

Formatting USB disk under Linux

Recently I had to format my USB disk as ext2fs. After this I had tough time converting it back to vfat partition scheme, so that I could use the disk on Windows systems.

Thanks to this blog post http://blog.dotkam.com/2008/07/10/restoreformat-usb-flash-drive/ I was able to reuse my USB disk under Windows. All credits to the original author. Just listing the commands below, just in case you too are looking for this:

Step 1: Insert the USB disk, check ‘dmesg’ to find out how it was detected by the system. In my case it was /dev/sdb.

Step 2: fdisk /dev/sdb

If fdisk detects any anamolies in the partition table, it will throw a prompt that it will try to correct it. This should be OK.

Use option ‘p’ to print the partition table.

If there is already a partition, delete it using ‘d’ option.

Create a new partition using ‘n’ option.

Save the changes by using ‘w’ option.

Step 3: mkfs.vfat -F 16 /dev/sdb1

That’s all. You can mount the disk on Linux now using, “mount -t vfat /dev/sdb1 <folder_path_where_you_want_to_mount>”. For unmount use, “umount /dev/sdb1”.
