Get SSH Server Authentication Methods

See more SSH Examples

Demonstrates how to get the authentication methods of an SSH server.

This example requires Chilkat v9.5.0.78 or greater.

Unicode C

#include <C_CkSshW.h>

void ChilkatSample(void)
    {
    BOOL success;
    HCkSshW ssh;
    const wchar_t *authMethods;

    success = FALSE;

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    ssh = CkSshW_Create();

    // To get the authentication methods offered by an SSH server, we first connect.
    success = CkSshW_Connect(ssh,L"example.com",22);
    if (success != TRUE) {
        wprintf(L"%s\n",CkSshW_lastErrorText(ssh));
        CkSshW_Dispose(ssh);
        return;
    }

    // Next, we call GetAuthMethods to receive a comma separated list of authentication methods
    authMethods = CkSshW_getAuthMethods(ssh);
    if (CkSshW_getLastMethodSuccess(ssh) != TRUE) {
        wprintf(L"%s\n",CkSshW_lastErrorText(ssh));
        CkSshW_Dispose(ssh);
        return;
    }

    // For example: publickey,password,keyboard-interactive
    wprintf(L"Authentication methods suported by this serve: %s\n",authMethods);

    // IMPORTANT:
    // Getting the authentication methods will intentionally disconnect from the server.
    // We'll need to re-connect, etc. to continue..

    // For example..
    success = CkSshW_Connect(ssh,L"example.com",22);
    if (success != TRUE) {
        wprintf(L"%s\n",CkSshW_lastErrorText(ssh));
        CkSshW_Dispose(ssh);
        return;
    }

    success = CkSshW_AuthenticatePw(ssh,L"myLogin",L"myPassword");
    if (success != TRUE) {
        wprintf(L"%s\n",CkSshW_lastErrorText(ssh));
        CkSshW_Dispose(ssh);
        return;
    }

    wprintf(L"SSH Authentication successful.\n");

    // ...

    CkSshW_Disconnect(ssh);


    CkSshW_Dispose(ssh);
