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 <CkSsh.h>

void ChilkatSample(void)
    {
    bool success = false;

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

    CkSsh ssh;

    // To get the authentication methods offered by an SSH server, we first connect.
    success = ssh.Connect("example.com",22);
    if (success != true) {
        std::cout << ssh.lastErrorText() << "\r\n";
        return;
    }

    // Next, we call GetAuthMethods to receive a comma separated list of authentication methods
    const char *authMethods = ssh.getAuthMethods();
    if (ssh.get_LastMethodSuccess() != true) {
        std::cout << ssh.lastErrorText() << "\r\n";
        return;
    }

    // For example: publickey,password,keyboard-interactive
    std::cout << "Authentication methods suported by this serve: " << authMethods << "\r\n";

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

    // For example..
    success = ssh.Connect("example.com",22);
    if (success != true) {
        std::cout << ssh.lastErrorText() << "\r\n";
        return;
    }

    success = ssh.AuthenticatePw("myLogin","myPassword");
    if (success != true) {
        std::cout << ssh.lastErrorText() << "\r\n";
        return;
    }

    std::cout << "SSH Authentication successful." << "\r\n";

    // ...

    ssh.Disconnect();
    }
