Where Does OpenSnitch Store Rules and Config on Linux?
OpenSnitch keeps daemon config in /etc/opensnitchd with per app rules beside it.
Last updated
OpenSnitch splits daemon settings from firewall rules. /etc/opensnitchd holds opensnitchd.conf plus the rules tree with per application allow and deny entries. The GUI writes the same files when you click through prompts.
Back up the whole /etc/opensnitchd tree to migrate decisions. Rule files are JSON per app and merge cleanly. Restart the daemon after restores and confirm the default action matches your stance.
Where OpenSnitch stores this, by platform
/etc/opensnitchd
Daemon conf plus rules folder. Root owned. Copy with the daemon stopped for consistent restores across machines.
