3 = Introduction =

|
4
|
|
|
5 This module adds two commands to the telnet console, `c2s:showtls()` and
|
|
|
6 `s2s:showtls()`. These commands shows TLS parameters, such as ciphers and key
|
|
|
7 agreement protocols, of all c2s or s2s connections.

9 = Configuration =
|
|
|
10
|
|
|
11 Just add the module to the `modules_enabled` list. There is no other configuration.

|
|
|
21
|
|
|
22 Simply type `c2s:showtls()` to show client connections or `s2s:showtls()`
|
|
|
23 for server-to-server connections. These commands can also take a JID for
|
|
|
24 limiting output to matching users or servers.
