Change the Server's Hostname

Run the below commands to change your server's hostname to "sendy"

sudo hostnamectl set-hostname sendy

sudo hostnamectl set-hostname "sendy" --pretty
Run the below command to make sure that the hostname was changed successfully:

hostnamectl
Run the following command to open the /etc/hosts file with vi:

sudo vi /etc/hosts

Insert a new line to the top of this file to indicate your new hostname. This new line should look like what is highlighted in blue below:

**127.0.0.1 sendy
127.0.0.1 localhost
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts**

Press Esc, then press the colon key (:), then type wq and then press Enter to save the changes and then close vi.
Run the following command to disconnect from the server:

exit
Connect back into the server again using Putty and make sure that your command prompt shows the new hostname. Your command prompt should look similar to this:
```
**ubuntu@sendy:~$**
```
