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.

C

#include <C_CkSsh.h>

void ChilkatSample(void)
    {
    BOOL success;
    HCkSsh ssh;
    const char *authMethods;

    success = FALSE;

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

    ssh = CkSsh_Create();

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

    // Next, we call GetAuthMethods to receive a comma separated list of authentication methods
    authMethods = CkSsh_getAuthMethods(ssh);
    if (CkSsh_getLastMethodSuccess(ssh) != TRUE) {
        printf("%s\n",CkSsh_lastErrorText(ssh));
        CkSsh_Dispose(ssh);
        return;
    }

    // For example: publickey,password,keyboard-interactive
    printf("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 = CkSsh_Connect(ssh,"example.com",22);
    if (success != TRUE) {
        printf("%s\n",CkSsh_lastErrorText(ssh));
        CkSsh_Dispose(ssh);
        return;
    }

    success = CkSsh_AuthenticatePw(ssh,"myLogin","myPassword");
    if (success != TRUE) {
        printf("%s\n",CkSsh_lastErrorText(ssh));
        CkSsh_Dispose(ssh);
        return;
    }

    printf("SSH Authentication successful.\n");

    // ...

    CkSsh_Disconnect(ssh);


    CkSsh_Dispose(ssh);

    }
