Rollover to the Ubuntu Server 16.04

We vps,In general, Ubuntu is still easy to use,On the one hand it is more friendly to novice,On the other hand are some common service configuration can be a key installation。Plus Niubi ufw,Really perfect。

but,Now not all vps service providers are able to provide the latest Ubuntu Server 16.04,what a pity。It has so many benefits of,For example, the native library is php7,No additional compiler ......

So since it is linux,Will be able to directly upgrade to the new version - I remember Ubuntu supports this rollover。

The highest hand only got a Ubuntu 14.04 Desktop mirror vps,We will try to give it to roll up 16.04 lts。

Use the following command to start the upgrade,Before you begin,Update Manager detects the server you are logged in through ssh,It will prompt you for the upgrade is very insecure - but that's okay,After all, we have failed can also reload it ...... summary,It also gives a first-aid program,The upgrade process will start ssh service in a new port,Once the upgrade failed,You should also be able to log on through the specified port vps。

This time to remember the prompts to terminate the upgrade process to ufw or IPtables release adds the specified port。

Executive upper command again to start the upgrade,There will be no warning,But directly start。

After the update is to press Y to confirm the source。

By the late installation,Some services will need to restart,Here you need to select OK,selected Yse .。

Acknowledging that some services will be restarted during the upgrade process

Acknowledging that some services will be restarted during the upgrade process

Final,After installation,The system will prompt you to delete obsolete packages,Confirm,Retention is useless。

          1. I just want to detect the next gateway for UDP packets is a loud noise filtering 53,Only allow DNS packets or any type are allowed,Because some of the hot spots is to allow all packets ...... thought through Telnet from UDP53,nc,nmap ...... first placed it on

    1. This is one,But I still like to use the latest version of the system,One is the use of a number of long,Another will support a number of new technologies,The old system,Although as stable,But the use of these techniques must manually compile,Lot of trouble:)
