Browse Source

<h4>Shutdown the router</h4>
Graceful shutdown lets the router satisfy the agreements it has already made
before shutting down, but may take a few minutes. If you need to kill the
router immediately, that option is available as well.<br />
<input type="submit" name="action" value="Shutdown gracefully" />
<input type="submit" name="action" value="Shutdown immediately" />
<input type="submit" name="action" value="Cancel graceful shutdown" />
<h4>Systray integration</h4>
On the windows platform, there is a small application to sit in the system
tray, allowing you to view the router's status (later on, I2P client applications
will be able to integrate their own functionality into the system tray as well).
If you are on windows, you can either enable or disable that icon here. <br />
<input type="submit" name="action" value="Enable systray icon" />
<input type="submit" name="action" value="Disable systray icon" />
<h4>Run on startup</h4>
On the windows platform, you can control whether I2P is run on startup or not by
selecting one of the following options - I2P will install (or remove) a service
accordingly. On *nix machines, you need root permissions to add a script
to be run on startup (we hope you know better than to run I2P as root ;). To
have I2P run (or not run) at startup on *nix machines, please run
<code>install_i2p_service_unix</code> or <code>install_i2p_service_unix</code>
as root.<br />
<input type="submit" name="action" value="Run I2P on startup" />
<input type="submit" name="action" value="Don't run I2P on startup" />
