lifekeeper

LifeKeeper is a simple yet practical software that performs a straightforward task of printing an ASCII NUL character every 30 seconds. While it might seem trivial to some, it could be a life-saver for people who rely on remote connections through firewalls.

Despite its lack of visual effects, LifeKeeper can be helpful for those who need to keep their connection active. With this software running in the background, even someone who is monitoring the connection for activity will see that the connection is still ongoing.

In particular, those who are dealing with masquerading firewalls may find LifeKeeper to be a valuable addition to their toolkit. Often, these firewalls are configured to terminate connections that appear inactive for a certain period. LifeKeeper can prevent this from happening by regularly sending a signal to the firewall, indicating that the connection is still in use.

Overall, if you're someone who relies on remote connections or deals with masquerading firewalls, give LifeKeeper a try. Its simple yet effective solution could save you from frustrating connection losses.
