User is not in the sudoers file. This incident will be reported(Solved)

When you install Ubuntu, it will ask you to set username and password and that will be your administrator. But after entering Ubuntu in the network, When you start with any network user it will show you the error "User is not in the sudoers file. This incident will be reported." This error can be easily solved. Just follow the following steps:
1. When you are installing Ubuntu, It will ask you about the partition.
2. You have to do is just make 4 partitions namely:
         1. / partition
         2. /boot partition
         3. /username partition
         4. Swap partition
The /username partition will be in the name of your network administrator. That will do the work. After that if u login in ubuntu with any user it will not show the error User is not in the sudoers file. This incident will be reported."

Some simple steps to protect your network from hackers:


Some simple steps to protect your network from hackers:

1) Don’t give easy passwords so that anybody can guess it.
Have a combination of complicated passwords that even a hacker can never hack.
2) Don’t Give passwords such as name, phone numbers etc. 
3) Close all those useless ports which are not in use.
4) Keep the firewall on.
5) Keep your antivirus up to date.
6) Don’t use server from your admin account, make other dummy account with some limited but useful access.
7) Never allow any other to attach pendrive or any mass storage devices, it may contain any hacking tool which can get all your passwords.
8) Use your USB for booting process. That will tighten the security.
9) Use tools like folder lock and others to lock some important data.
10) Take regular backup of the server.
