Date: 5/26/2019

Abstract:
This essay will focus on visiting home linux server from outside.
Step 1：
Go to the following website to register an account
https://www.noip.com/
For example:
username: YourOwnAccount@gmail.com
password: YourOwnPassword

Step 2: In your server, Download client & install & configure
Download the linux version of the noip client from the following link:
https://www.noip.com/download?page=linux

Once you have opened your Terminal window, log in as the “root” user. You can become the root user from the command line by entering “sudo -s” followed by the root password on your machine.

1. cd /usr/local/src/
2. wget http://www.no-ip.com/client/linux/noip-duc-linux.tar.gz
3. tar xf noip-duc-linux.tar.gz
4. cd noip-2.1.9-1/
5. make install
6. /usr/local/bin/noip2 -C (dash capital C, this will create the default config file)
7. /usr/local/bin/noip2  & # run noip2 in backgroud

Step 4: port forwarding:
Suppose you get you domain name from noip.com like the following:

http://YouOwnDDNSaccount.ddns.net/
Then you can setup port forwarding in the following
http://YouOwnDDNSaccount.ddns.net/port_forwarding.php
you can also try:
http://192.168.10.1/
the default
user:admin
pass:password

Step 5: Check:
Option 1:you can validate step3 with local ip of your server:
for example: (port: 22)
ssh yourUserName@10.0.0.136

Option 2:
try port 22 and ip: 12.34.56.78 (just for example)

Option 3: testing outside your home network (outside your home wifi)
ssh yourUserName@12.34.56.78
Note, you can not test option 3 within your home network.
