297
|
|
|
|
|
|
|
|
298
|
|
|
|
|
|
|
POE::Component::Server::Ident is a L component that provides |
299
|
|
|
|
|
|
|
a non-blocking Identd for other components and POE sessions. |
300
|
|
|
|
|
|
|
|
301
|
|
|
|
|
|
|
Spawn the component, give it an an optional lias and it will sit there waiting for Ident clients to connect. |
302
|
|
|
|
|
|
|
Register with the component to receive ident events. The component will listen for client connections. |
303
|
|
|
|
|
|
|
A valid ident request made by a client will result in an 'identd_server' event being sent to your |
304
|
|
|
|
|
|
|
session. You may send back 'ident_server_reply' or 'ident_server_error' depending on what the client |
305
|
|
|
|
|
|
|
sent. |
306
|
|
|
|
|
|
|
|
307
|
|
|
|
|
|
|
The component will automatically respond to the client requests with 'ERROR : HIDDEN-USER' if your |
308
|
|
|
|
|
|
|
sessions do not send a respond within a 10 second timeout period. This can be adjusted with 'Random' |
309
|
|
|
|
|
|
|
and 'Default' options to spawn(). |

318
|
|
|
|
|
|
|
|
319
|
|
|
|
|
|
|
'Alias', a kernel alias to address the component with; |
320
|
|
|
|
|
|
|
'BindAddr', the IP address that the component should bind to, |
321

|
|
|
|
|
|
|
'Multiple', specify whether the component should allow multiple ident queries |
324
|
|
|
|
|
|
|
from clients by setting this to 1, default is 0 which terminates |
325
|
|
|
|
|
|
|
client connections after a response has been sent; |
326
|
|
|
|
|
|
|
'TimeOut', this is the idle timeout on client connections, default |
327
|
|
|

is 60 seconds, accepts values between 60 and 180 seconds. |
328
|

|
|
|
|
|
|
response. |
330
|
|
|
|
|
|
|
'Random', the component will generate a random userid string if your sessions |
331
|
|
