Description
-
Called when server requests a response to login challenge.
Syntax
-
void (*LoginChallenge)(void *Sftp, char
*Challenge, char **Response);
The LoginChallenge callback syntax has these parts:
| void
*Sftp |
Handle of the created Sftp
instance. |
| char
*Challenge |
Holdsthe challenge expression
provided by the server. |
| char **Response |
Value you should provide this as
the answer to the challenge. |
Remarks
-
LoginChallenge callback will be called
when wodSFTP tries to use
Keyboard-Interactive authentication. This type of authentication is
selected when you set
Authentication
= AuthPassword (or AuthAny by default) but password
authentication fails. In this case wodSFTP tries Keyboard-Interactive
authentication (if it is available on the server) which causes the server to send a
'challenge' request that can be shown on the user's screen and to which you must
answer with the proper response in order to become authenticated.
-
-
Often, the server just sends something like 'please enter your
password', but on some configurations this can be any
question. For example, the server may request that you enter a
one-time-password, or your token ID.
-
-
NOTE: this callback is called only if
you have created instance of
SftpEventsStruct structure, and set up its LoginChallenge member to
function implementing it.
