Gnoppix Linux

A Glimpse at gnoppixctl. Now with a Friendly Face!


COMMANDS

Section titled “COMMANDS”

  • start Starts the Tor service and redirects all outgoing network traffic through the Tor network, enhancing anonymity.

  • stop Stops the Tor service and reverts network traffic redirection, allowing all traffic to flow through the clearnet (unencrypted and untorified internet).

  • status Displays the current status of the Tor service, indicating whether it is running and if traffic is being routed through Tor.

  • restart Restarts the Tor service and reapplies the necessary traffic redirection rules. This can be useful for refreshing the Tor connection or resolving connectivity issues.

  • autowipe Enables memory wiping at system shutdown. When enabled, the system will attempt to securely clear RAM contents during the shutdown process, helping to prevent sensitive data from being recovered.

  • autostart Configures gnoppixctl to automatically start and apply its network rules at system boot. This ensures that Tor connectivity and traffic redirection are active from the moment the system starts.

  • ip Retrieves and displays your current remote IP address as seen by external services. When Tor is active, this will show your Tor exit node’s IP address.

  • chngid Requests Tor to change its identity, which typically results in a new Tor exit node and a different IP address for your connection. This is useful for obtaining a new circuit and improving anonymity.

  • chngmac Randomizes the MAC addresses of all active network interfaces on the system. This can help to prevent tracking based on hardware identifiers.

  • rvmac Reverts the MAC addresses of all network interfaces to their original, permanent values. Use this command to undo changes made by chngmac.

  • version Prints the version information of the gnoppixctl utility and then exits.

Cheatcodes

Section titled “Cheatcodes”

In case the application looks bit blurry, it mean you’re not using gnoppix, jokes aside. Is is a wayland problem, GTK3 does not support fractional scaling. The app renders at 1x, then kwin_wayland upscales it with bilinear filtering — this is what makes everything blurry, regardless of font size or anti-aliasing settings.

Fix options:

Per-app launch — run with GDK_DPI_SCALE to compensate (avoids compositor upscaling): GDK_SCALE=1 GDK_DPI_SCALE=1.5 sudo gnoppixctl-gui

(adjust 1.5 to match your screen scale)

System-wide GTK3 fix — create ~/.config/gtk-3.0/settings.ini:

[Settings] gtk-xft-dpi=147456 (147456 = 144 DPI = 96 × 1.5) — tells GTK3 to render fonts at the correct size without compositor scaling.

KDE setting — System Settings → Display → set “Scale method” to “Prefer crisp text” (if available) or disable fractional scaling and use integer scaling instead.
