mod_rest: Reject password that fails saslprep earlier (thanks tgy)
Prevents an error later if/when passing the password through saslprep a
second time in the authentication module, since the prep functions now
reject nil
The error reporting could be improved but that would involve adding a
way to pass errors back out of the check_credentials() function.

--- 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.
