mod_firewall: SUBSCRIBED: Flip subscription check to match documentation
The documentation claims that this condition checks whether the recipient is
subscribed to the sender.
However, it was using the wrong method, and actually checking whether the
sender was subscribed to the recipient.
A quick poll of folk suggested that the documentation's approach is the right
one, so this should fix the code to match the documentation.
This should also fix the bundled anti-spam rules from blocking presence from
JIDs that you subscribe do (but don't have a mutual subscription with).

--- labels: - 'Stage-Stable' summary: Granular remote host blacklisting plugin ... Details ======= As often it's undesiderable to employ only whitelisting logics in public environments, this module let's you more selectively restrict access to your hosts (component or server host) either disallowing access completely (with optional exceptions) or blacklisting certain sources. Usage ===== Copy the plugin into your prosody's modules directory. And add it between your enabled modules into the global section (modules\_enabled): - The plugin can work either by blocking all remote access (s2s) to a certain resource with optional exceptions (useful for components) - Or by selectively blocking certain remote hosts through blacklisting (by using host\_guard\_selective and host\_guard\_blacklisting) Configuration ============= Option name Description ----------------------------------- --------------------------------------------------------------------------------------------------- host\_guard\_blockall A list of local hosts to protect from incoming s2s host\_guard\_blockall\_exceptions A list of remote hosts that are always allowed to access hosts listed in host\_guard\_blockall host\_guard\_selective A list of local hosts to allow selective filtering (blacklist) of incoming s2s connections host\_guard\_blacklist A blacklist of remote hosts that are not allowed to access hosts listed in host\_guard\_selective Example ------- ``` {.lua} host_guard_blockall = { "no_access.yourhost.com", "no_access2.yourhost.com" } -- insert here the local hosts where you want to forbid all remote traffic to. host_guard_blockall_exceptions = { "i_can_access.no_access.yourhost.com" } -- optional exceptions for the above. host_guard_selective = { "no_access_from_blsted.myhost.com", "no_access_from_blsted.mycomponent.com" } -- insert here the local hosts where you want to employ blacklisting. host_guard_blacklist = { "remoterogueserver.com", "remoterogueserver2.com" } -- above option/mode mandates the use of a blacklist, you may blacklist remote servers here. ``` The above is updated when the server configuration is reloaded so that you don't need to restart the server. Compatibility ============= - Works with 0.8.x, successive versions and trunk.
