sudo: /var/lib/sudo/user1 writable by non-owner (040777), should be mode 0700

Here is the solution for this problem. I couldn’t run some of commands in my ubuntu machine as normal user. I supposed to use sudo for those commands like ifconfig, scp etc. This is due to the problem with $PATH environment variable. 

Do the following steps

1. edit .bashrc file

$ cd ~

$ vi .bashrc

2. Go to the end of file, append the following line and save it

PATH=$PATH:/sbin

3. Reload the .bashrc file with reboot the machine

$ source .bashrc

Thats all

Now you are out of this problem. 

Mobile Portability Number (MNP)

The dream becomes true, the Mobile Portability Number launched in india.

Really its a great facility to the people, also the people gets lots benefits because of the competition between the network service providers.

MNP launched first at Rohtak in Haryana

we can use this service by the cost of 19. The amount is fixed by the TRAI.

Procedure:

Send an sms (PORTMobile Number) to 1900 from the number which you want to port

Then we will receive a Unique Porting Code(UPC) by sms from current service provider

We should give the prescribed application form to the new service provider with UPC as reference code.

Porting to be completed within seven days.

Once we changed the service provider then again we can not change the service provider until 90 days.

NOTE: The balance will not be carried forward when the service provider transferred to the next provider.

Tamilnudu government announced the people who wants to get the driving license or LLR can apply through the Online.

This would enable the license seekers to save time spent on visiting Regional Transport Offices and waiting there for long hours. Since an acknowledgment was given online, those registering for LLR could note down the number and approach the nearest RTOs for getting LLRs after passing the initial tests online and payment of requisite fees.
