TTL Editor

TTL Editor is an application designed for users who need to modify network configuration rules, particularly concerning the editing of IPv4 packets transmitted over a specified interface. It is suitable for advanced users with rooted devices and can be instrumental in altering the Time to Live (TTL) value of data packets to mask tethering or mobile hotspot usage, especially if such services are not included in your mobile plan.

Leveraging the Linux iptables, a robust system for network packet filtering and manipulation, the app's graphical interface simplifies the process of setting up network rules—without the need to manually edit system files or worry about persistent changes, as all configurations are reset after a reboot.

Key features include:

- Simple and intuitive graphical front-end interface

- Capability to edit all outgoing IPv4 packets over a given network interface

- No permanent file changes, with configurations resetting after reboot

- Provision of source code for transparency

To effectively run the app, the device must have root access, a functioning ‘iptables’ binary, and kernel support for Netfilter TTL packet manipulation. Additionally, it requires network access permissions to identify network interfaces and their IPs, as well as root access permissions to make the necessary TTL packet edits.

Continual improvements are anticipated, with features like ‘set at boot’ planned for future updates. For any issues encountered, users can submit a logcat for review, reaffirming the responsive support system provided.

Overall, if you are technologically adept and require control over your device’s tethering signature, the utility presents an efficient and user-friendly solution.
