CheckMyIP - myip.bsd.cafe

A Telnet, SSH, DNS and Simple HTTP Based Public IP Address Lookup Service


USAGE

DNS

  • DNS TXT Record:
    • Retrieve your IP via a DNS TXT record: dig +short myip.bsd.cafe TXT @myip.bsd.cafe

Telnet

  • Default: telnet myip.bsd.cafe
  • IPv4: telnet myip4.bsd.cafe
  • IPv6: telnet myip6.bsd.cafe

SSH

  • Default: ssh myip.bsd.cafe
  • IPv4: ssh myip4.bsd.cafe
  • IPv6: ssh myip6.bsd.cafe
  • Your SSH client may require you to enter a username. You can use anything you want (ssh -l username myip.bsd.cafe)

CURL

  • Default: curl -L myip.bsd.cafe
  • IPv4: curl -L myip4.bsd.cafe
  • IPv6: curl -L myip6.bsd.cafe

WGET

  • Default: wget -qO- myip.bsd.cafe
  • IPv4: wget -qO- myip4.bsd.cafe
  • IPv6: wget -qO- myip6.bsd.cafe

For HTTP (CURL and WGET above), use myip.bsd.cafe/raw to get only the IP address. This also works for the HTTP IPv4 and IPv6 addresses.

WHAT IS CHECKMYIP

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 *BSD or 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 myip.bsd.cafe public services were created with this in mind.


HOW TO USE

Using the public myip.bsd.cafe service is pretty easy: simply connect to them with a terminal client. You can use a telnet client with TCP port 23 (telnet myip.bsd.cafe), a SSH client with TCP port 22 (ssh myip.bsd.cafe), or CURL (curl -L myip.bsd.cafe). 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 myip.bsd.cafe).

You can also browse to the HTTP version of the service at myip.bsd.cafe 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.


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 myip.bsd.cafe). 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"])

INSTALL PROCESS

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.

Install Dependencies (for example, on a FreeBSD jail)

pkg install python39 py39-gssapi py39-paramiko py39-dnspython

Clone Repo and install

git clone https://brew.bsd.cafe/BSDCafe/checkmyip
cp checkmyip/checkmyip.py /usr/local/bin
chmod a+rx /usr/local/bin/checkmyip.py

Create Service (vi /usr/local/etc/rc.d/checkmyip)

#!/bin/sh

# PROVIDE: checkmyip
# REQUIRE: DAEMON
# KEYWORD: shutdown

. /etc/rc.subr

name="checkmyip"
rcvar=checkmyip_enable

load_rc_config $name

: ${checkmyip_enable:=no}
: ${checkmyip_user:="nobody"}

pidfile="/var/run/${name}.pid"
command="/usr/local/bin/checkmyip.py"
command_interpreter="/usr/local/bin/python3.9"
command_args="&"
start_precmd="checkmyip_precmd"

checkmyip_precmd() {
    install -o ${checkmyip_user} -g ${checkmyip_user} /dev/null ${pidfile}
}

run_rc_command "$1"

Finish and Start Up Service

chmod a+rx /usr/local/etc/rc.d/checkmyip
mkdir /var/log/checkmyip
chown nobody:nobody /var/log/checkmyip

service checkmyip enable
service checkmyip start
