Batch ping of Ubuntu Server to select the fastest Source

It is inconvenient to operate shell on a virtual machine. simply make the virtual machine a server and use putty to connect it... I learned the basic Linux Script Programming and used it to detect the fastest source. Back up the method.

Previously, I used sudo passwd root on Ubuntu Server to enable the root user. If not, remember to add "sudo" before the command ".

1. Back up the source list file cp/etc/apt/sources. list/etc/apt/sources. list. bak



2. Use vim to open-source list file vim sources. list

3. Press Esc, select all and delete (ggdG), paste the new source, save and exit (: wq ). I pinged one by one and thought the two below would be the best for me. Save the record. "Intrepid" is the code 8.04. If it is 9.04, change it to "jaunty.

5. update the source apt-get update.

6. Update the installed software package apt-get upgrade. If you want to update the entire system to the latest release, you can also update apt-get dist-upgrade.

Well, in order to facilitate future testing of the source speed, you can simply write a script to Perform Batch detection.

Run vim ping. sh to create a new file, write the following script, and save the file.

#! /Bin/sh
For ip in 'cat testlist'
Do
Ping-c 5-q $ ip;
Done
Create a new testlist file to save the source domain name vim testlist

Here we need to run chmod 755 ping. sh to grant it the execution permission, and then run./ping. sh. The result will be displayed on the screen. For the sake of simplicity, I added the-q parameter to the ping command to display only the final statistical results, and ping the command for five consecutive times.
