.SH NAME
|
|
libssh2_userauth_list - list the authentication methods supported by a server
|
|
.SH SYNOPSIS
|
|
#include <libssh2.h>
|
|
|
|
char *
|
|
libssh2_userauth_list(LIBSSH2_SESSION *session, const char *username, unsigned int username_len);
|
|
|
|
.SH DESCRIPTION
|
|
\fIsession\fP - Session instance as returned by
|
|
.BR libssh2_session_init_ex(3)
|
|
|
|
\fIusername\fP - Username which will be used while authenticating. Note
|
|
that most server implementations do not permit attempting authentication
|
|
with different usernames between requests. Therefore this must be the
|
|
same username you will use on later userauth calls.
|
|
|
|
\fIusername_len\fP - Length of username parameter.
|
|
|
|
Send a \fBSSH_USERAUTH_NONE\fP request to the remote host. Unless the
|
|
remote host is configured to accept none as a viable authentication
|
|
scheme (unlikely), it will return \fBSSH_USERAUTH_FAILURE\fB along with a
|
|
listing of what authentication schemes it does support. In the unlikely
|
|
event that none authentication succeeds, this method with return NULL. This
|
|
case may be distinguished from faily by examining
|
|
.BR libssh2_userauth_authenticated(3)
|
|
|
|
.SH RETURN VALUE
|
|

|
|
internally managed by libssh2. On failure ruturns NULL.
|
|
|
|
