Unable to resolve host '' ubuntu 14.04



I face this issue when I was adding new web site to my web server which is hosted in Digital Ocean Cloud service.  So what happened was, when I using sudo commands to restart or reload apache2 server its restring with following error messages.

For me everything worked well despite these two  error messages.

1. Error 1 - Unable to resolve host 'YOUR HOST NAME'  .
2. Error 2 - sum_functio_error() //I don't remember this function name I'll update this later.

So the fix was very simple.

First open your hotsts file.

sudo nano /etc/hosts

Output File

127.0.1.1 hostname
127.0.0.1 localhost


sudo nano /etc/hostname


Output File

hostnamexxx



So in my case hostname in hostname file and hosts file difference.So  I put the hostnamexxx in hosts file and restarted the server.

*You have to restart your server to apply any hosts file changes.


Please comment bellow if you need further explanation.

SMS sending from old number even after transferring the number - iphone 6 ( Australia )


I came across this problem after I changed my mobile provider. Transfer of number was successful and I was able to call from my old number. But the problem was after I send  a SMS its actually showed my new peremptory number to the recipient. So I ended up with so many 'Who is this' messages.

So lets fix this for iPhone 6 ( iOS 10.3.2 ) .  

1. Turn of iMesseges.

  • Settings > Messages > Switch off iMessges
2. Turn of facetime

  • Settings > Facetime > Switch off Facetime
3. Reset network settings of your iphone. After this your iphone will be restarted.

4. After you restarted the iphone switch on facetime and imessage,
