6 As often it's undesiderable to employ only whitelisting logics in public environments, this module let's you more selectively |
|
|
7 restrict access to your hosts (component or server host) either disallowing access completely (with optional exceptions) or |
|
|
8 blacklisting certain sources. |

|
12 Copy the plugin into your prosody's modules directory. |
|
|
13 And add it between your enabled modules into the global section (modules_enabled): |

14 |
|
|
15 * The plugin can work either by blocking all remote access (s2s) to a certain resource with optional exceptions (useful for components) |
|
|
16 * Or by selectively blocking certain remote hosts through blacklisting (by using host_guard_selective and host_guard_blacklisting) |

|
|
27 <code language="lua"> |
|
|
28 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. |
|
|
29 host_guard_blockall_exceptions = { "i_can_access.no_access.yourhost.com" } -- optional exceptions for the above. |
|
|
30 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. |
|
|
31 host_guard_blacklist = { "remoterogueserver.com", "remoterogueserver2.com" } -- above option/mode mandates the use of a blacklist, you may blacklist remote servers here. |
