-----------------------------------------
###   WHAT IS CHECKMYIP   ###
Everybody has used a service like [WhatIsMyIP.com](https://www.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](https://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](#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
```

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
```


-----------------------------------------
###   UPDATES IN V1.0.0 --> V1.1.0   ###

**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.


-----------------------------------------
###   UPDATES IN V1.1.0 --> V1.3.0   ###

- README updated for install on Ubuntu instead of CentOS
- Small tweaks to support Python3
