(Ruby) Get SSH Server Authentication Methods

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

This example requires Chilkat v9.5.0.78 or greater.

Chilkat Ruby Downloads install from rubygems.org gem install chilkat or download... Ruby Library for Windows, MacOS, Linux, Alpine Linux

require 'chilkat'

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

ssh = Chilkat::CkSsh.new()

# To get the authentication methods offered by an SSH server, we first connect.
success = ssh.Connect("example.com",22)
if (success != true)
    print ssh.lastErrorText() + "\n";
    exit
end

# Next, we call GetAuthMethods to receive a comma separated list of authentication methods
authMethods = ssh.getAuthMethods()
if (ssh.get_LastMethodSuccess() != true)
    print ssh.lastErrorText() + "\n";
    exit
end

# For example: publickey,password,keyboard-interactive
print "Authentication methods suported by this serve: " + authMethods + "\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)
    print ssh.lastErrorText() + "\n";
    exit
end

success = ssh.AuthenticatePw("myLogin","myPassword")
if (success != true)
    print ssh.lastErrorText() + "\n";
    exit
end

print "SSH Authentication successful." + "\n";

# ...

ssh.Disconnect()
