NAME

6       Net::SSH::Perl::Auth::Rhosts_RSA - Perform Rhosts-RSA authentication
7

SYNOPSIS

9           use Net::SSH::Perl::Auth;
10           my $auth = Net::SSH::Perl::Auth->new('Rhosts_RSA', $ssh);
11           print "Valid auth" if $auth->authenticate;
12

DESCRIPTION

14       Net::SSH::Perl::Auth::Rhosts_RSA performs Rhosts with RSA
15       authentication with a remote sshd server. This is standard Rhosts
16       authentication, plus a challenge-response phase where the server RSA-
17       authenticates the client based on its host key. When you create a new
18       Rhosts_RSA auth object, you give it an $ssh object, which should
19       contain an open connection to an ssh daemon, as well as any data that
20       the authentication module needs to proceed. In this case, the $ssh
21       object must contain the name of the user trying to open the connection.
22
23       Note that the sshd server will require two things from your client:
24
25       1. Privileged Port
26           sshd will require your client to be running on a privileged port
27           (below 1024); this will, in turn, likely require your client to be
28           running as root. If your client is not running on a privileged
29           port, the Rhosts-RSA authentication request will be denied.
30
31           If you're running as root, Net::SSH::Perl should automatically
32           detect that and try to start up on a privileged port. If for some
33           reason that isn't happening, take a look at the Net::SSH::Perl
34           docs.
35
36       2. Private Host Key
37           In order to do RSA-authentication on your host key, your client
38           must be able to read the host key. This will likely be impossible
39           unless you're running as root, because the private host key file
40           (/etc/ssh_host_key) is readable only by root.
41
42       With that aside, to use Rhosts-RSA authentication the client sends a
43       request to the server to authenticate it, including the name of the
44       user trying to authenticate, as well as the public parts of the host
45       key. The server first ensures that the host can be authenticated using
46       standard Rhosts authentication (shosts.equiv, hosts.equiv, etc.).  If
47       the client passes this test, the server sends an encrypted challenge to
48       the client. The client must decrypt this challenge using its private
49       host key, then respond to the server with its response.
50
51       Once the response has been sent, the server responds with success or
52       failure.
