# CheckMyIP ![CheckMyIP][logo]
A Telnet and SSH based IP Lookup Service
-----------------------------------------
### VERSION ###
The version of CheckMyIP documented here is: **v1.0.0**
-----------------------------------------
### TABLE OF CONTENTS ###

5. [Contributing](#contributing)
-----------------------------------------
### WHAT IS CHECKMYIP ###
Everybody has used a service like [WhatIsMyIP.com](whatismyip) before. If you are an IT engineer or even an amateur technology enthusiast, then you have probably had a reason to check to see your public IP address. This service works great when a browser is available, but at times it is not. We often find ourselves logged into a remote Linux machine or a network switch/router which has a command line and terminal clients (Telnet and SSH), but no browser. The CheckMyIP app and the **TelnetMyIP.com** and **SSHMyIP.com** public services were created with this in mind.
-----------------------------------------
### HOW TO USE ###
Using the public **TelnetMyIP.com** and **SSHMyIP.com** services is pretty easy: simply connect to them with a terminal client. You can use a telnet client with TCP port 23 (`telnet telnetmyip.com`), or a SSH client with TCP port 22 (`ssh telnetmyip.com`). The SSH connection requires no authentication, but your SSH client may require you to enter a username, you can use anything you want as it gets ignored anyways(`ssh -limrootbitch telnetmyip.com`).
To enable the use of this service as a simple API, the response to queries is formatted as a JSON document. See the [Using the API](#using-the-api) section.
-----------------------------------------
### INSTALL PROCESS ###
Change Linux SSH Port to TCP222 and reboot
```
sudo sed -i --follow-symlinks 's/#Port 22/Port 222/g' /etc/ssh/sshd_config
shutdown -r now
```
Install Dependencies

pip install python-gssapi
```
Install Binary
```
cp checkmyip.py /bin/checkmyip
chmod 777 /bin/checkmyip
mkdir -p /etc/checkmyip/
```
Create Service (`vi /etc/init.d/checkmyip`)
```

restart)
$0 stop
$0 start

*)
echo "Usage: $0 {status|start|stop|restart}"
exit 1
esac
```
Finish and Start Up Service
```
chmod 777 /etc/init.d/checkmyip
chkconfig checkmyip on
service checkmyip start
service checkmyip status
```
-----------------------------------------
### USING THE API ###
The CheckMyIP code contains the `CheckMyIP_Client` class which is an API client example which can be used to query a CheckMyIP server (like telnetmyip.com). Below is an example of how you can use it.
```
from checkmyip import CheckMyIP_Client
client = CheckMyIP_Client()
ipdict = client.get()
print("My IP is %s" % ipdict["ip"])
print("I used port number %s" % ipdict["port"])
```
