I have always liked the idea of running a server from whatever device I have in my pocket. With IPv4 that is basically impossible on mobile data because your phone is behind carrier grade NAT. IPv6 changes the game. If your carrier gives you a real IPv6 address, your phone can be on the public internet without any special tricks.

I tried it on my own phone and it works.

Finding Your IPv6 Address

First, check if your phone has IPv6 and whether it is a global address. On Android you can find it in Settings → About Phone → Status → IP address, or in Termux by running:

ip -6 addr show

Look for something that starts with 2001: or 2400:. If it starts with fe80: that is a link local address and will not work for this. On iOS it is in Settings → Wi-Fi → tap your connected network → IPv6 Address.

Running a Server

On Android, the easiest way is with Termux. Install Python and start a simple HTTP server:

pkg install python
python -m http.server 8080 --bind ::

The bind option with :: makes it listen on all IPv6 interfaces. You can use a dedicated web server app too, but this is the quickest way to test. On iOS you can use Pythonista, iSH or any app with a built in web server.

Testing It

On your phone, open a browser and go to:

http://[your_ipv6_address]:8080

You need the square brackets for IPv6. If it works locally, try from another IPv6 capable device on the internet:

curl -6 http://[your_ipv6_address]:8080

If the page loads you have a public website running from your phone.

Things That Might Get in the Way

Some mobile ISPs block inbound IPv6 traffic. If that happens nothing will load from outside. Your IPv6 address might also change when you reconnect to the network. Running a server will also keep the radio active which drains battery faster. There is no HTTPS by default so traffic is not encrypted.

Making It Easier to Reach

Typing a long IPv6 address is inconvenient. You can use a free dynamic DNS service that supports IPv6 such as Dynv6 or DuckDNS. Once set up you can visit your server at an address like:

http://myname.dynv6.net:8080

Why Bother

For me it is about the novelty of hosting something directly from a phone with no cloud in between. It is handy for quick file sharing, testing apps from real external clients, or just playing with IPv6 in a practical way. It is not a production setup but it is a fun reminder that with IPv6 the internet can be end to end again.

What is Mobian?

Mobian is a project that aims to bring Debian to mobile devices while minimizing its specific customizations by upstreaming changes to the original Debian project. The project is maintained by two teams:

1. The Mobian Team – Responsible for maintaining downstream packages and handling image generation and distribution.
2. The DebianOnMobile Team – Maintains packages that are already part of the Debian archive.

With Mobian, users can install a full Debian-based Linux operating system on their mobile devices, enabling them to use traditional Linux tools on the go. More information about Mobian can be found on the official website: Mobian Project.

Installing Mobian

Mobian supports various mobile devices, with installation instructions available on the official Mobian Supported Devices page. Users can either:

• Build Mobian images locally following the mobian-recipes documentation.
• Download official Mobian images from Mobian Project.

For security-conscious users, Mobian images come with signature verification options to ensure integrity.

Why Mobian is Ideal for Amateur Radio Operators

Amateur radio operators are always on the lookout for efficient and flexible solutions to enhance their portable radio communication setups. Here are some key reasons why Mobian is a great fit:

1. Full Linux Environment on Mobile Devices

With Mobian, radio enthusiasts can leverage the power of Debian’s vast repository of open-source tools, including:

• Xastir – An APRS (Automatic Packet Reporting System) client.
• Fldigi – A software modem for digital modes like PSK31, RTTY, and more.
• WSJT-X – For weak-signal communication using modes like FT8 and WSPR.
• GNU Radio – For SDR (Software-Defined Radio) applications.

2. Software-Defined Radio (SDR) Integration

Mobian enables seamless integration with SDR tools like RTL-SDR, HackRF, and LimeSDR, allowing hams to experiment with digital signal processing, spectrum monitoring, and remote radio control directly from their mobile devices.

3. Portable APRS and GPS Tracking

Using Mobian on a mobile device equipped with GPS, operators can:

• Run APRS software to report their location over RF or the internet.
• Use GPS-based logging software for SOTA (Summits on the Air) and POTA (Parks on the Air) activities.
• Track other amateur radio stations using APRS maps.

4. Customizable and Open-Source

Unlike proprietary mobile operating systems, Mobian provides full control over software, privacy, and system configurations. Hams can customize their setups for:

• Emergency communication (EmComm) applications.
• Mesh networking using protocols like AREDN and Meshtastic.
• Remote transceiver control via SSH or web-based interfaces.

5. Secure and Privacy-Focused

Many amateur radio operators value privacy. Mobian, being Debian-based, prioritizes security and transparency, making it a great alternative to proprietary mobile OS platforms that collect user data.

Expanding the Possibilities with Mobian

Beyond amateur radio applications, Mobian serves as a versatile mobile platform for general-purpose computing, hacking, and privacy-focused mobile usage. Some additional possibilities include:

• Running packet radio applications for digital communications.
• Using VoIP and SIP clients for secure voice communications.
• Experimenting with LoRa and Meshtastic networks for long-range data exchange.
• Implementing automation and remote control via MQTT and other IoT protocols.

Mobian users can keep up with the latest developments, features, and community discussions by following the Mobian Blog.

Challenges and Considerations

While Mobian is an excellent project for amateur radio, users should be aware of some challenges:

• Limited device support – Not all smartphones can run Mobian, so users must check compatibility.
• Battery life – Running a full Linux system on mobile hardware may drain batteries faster than optimized mobile OSes.
• Hardware access – Some mobile hardware components may not have full driver support.

Mobian represents a powerful shift in mobile computing, bringing the flexibility of Debian to handheld devices. For amateur radio enthusiasts, this opens up exciting possibilities for portable APRS stations, SDR experimentation, and on-the-go digital communication. With continued development and community support, Mobian has the potential to become a staple in the amateur radio toolkit.

For those interested in trying Mobian, visit the Mobian Wiki and join discussions on Matrix, IRC, or Telegram to connect with fellow users and developers.
