A Telnet, SSH and Simple HTTP Based Public IP Address Lookup Service
- TELNET:
telnet telnetmyip.com - SSH:
ssh sshmyip.com- Your SSH client may require you to enter a username. You can use anything you want (
ssh -limrootbitch telnetmyip.com)
- Your SSH client may require you to enter a username. You can use anything you want (
- CURL:
curl telnetmyip.com - WGET:
wget -qO- telnetmyip.com
The version of CheckMyIP documented here is: v1.3.0
Everybody has used a service like WhatIsMyIP.com 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.
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), a SSH client with TCP port 22 (ssh sshmyip.com), or CURL (curl 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).
You can also browse to the HTTP version of the service at TelnetMyIP.com which will return a JSON reply with your IP information.
To enable the use of this service as a simple API, the response is formatted as a JSON document. See the Using the API section for information on how to leverage the API.
Note: You can also connect to ipv4.telnetmyip.com or ipv6.telnetmyip.com if you want to check a specific IP stack.
Note: The DNS records for telnetmyip.com and sshmyip.com point to the same services.
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("\nMy IP is %s\n" % ipdict["ip"])
print("\nI used port number %s\n" % ipdict["port"])
If you would rather set up your own private instance of CheckMyIP, then you can follow the below instructions to set it up for yourself.
Change Linux SSH Port to TCP 222 and reboot
sudo sed -i --follow-symlinks 's/#Port 22/Port 222/g' /etc/ssh/sshd_config
shutdown -r now

NEW FEATURES:
- Was seeing issues where SSH would be very slow to exchange. Likely related to log file sizes, so I change the logging function to turnover to new logging files every day.
- README updated for install on Ubuntu instead of CentOS
- Small tweaks to support Python3
