NAME ^

Net::Scan::SSH::Server::SupportedAuth - detect supported authentication method of SSH server

SYNOPSIS ^

  use Net::Scan::SSH::Server::SupportedAuth qw(:flag);

  my $scanner = Net::Scan::SSH::Server::SupportedAuth->new(host => 'localhost');

  ### get result as hash
  my $sa_hash = $scanner->scan_as_hash;
  #  $sa_hash = {'1' => {'password' => 0,'publickey' => 0},
  #              '2' => {'password' => 0,'publickey' => 1}};

  ### get result as bit flag
  my $sa = $scanner->scan;

  sub checker {
      my($label, $boolean) = @_;
      printf "%-26s: %s\n", $label, $boolean ? 't' : 'f';
  }
  checker("2-publickey only",
          ($sa->{2} == $AUTH_IF{publickey} && $sa->{1} == 0) );
  checker("any-publickey",
          (($sa->{1} | $sa->{2}) & $AUTH_IF{publickey}) );
  checker("2-publickey or 2-password",
          ($sa->{2} & ( $AUTH_IF{publickey} | $AUTH_IF{password} )) );

DESCRIPTION ^

Net::Scan::SSH::Server::SupportedAuth connect SSH server and probe protocol version and supported authentication method (publickey or password).

METHODS ^

new

  $scanner = Net::Scan::SSH::Server::SupportedAuth->new( %option )

This method constructs a new "Net::Scan::SSH::Server::SupportedAuth" instance and returns it. %option is to specify SSH server.

  key   value
  ========================================================
  host  "hostname" or "IP address" (default: '127.0.0.1')
  port  "port number" (default: '22')

scan

  $sa = $scanner->scan;

Do scan and return hash reference which contains information of supported authentication method.

  $sa = { VERSION => AUTH_FLAGS, VERSION => AUTH_FLAGS, ... }

  VERSION    : SSH protocol version. 1 or 2.
  AUTH_FLAGS : 32bit bit flags. to compare with %Net::Scan::SSH::Server::SupportedAuth::AUTH_IF.

scan_as_hash

  $sa_hash = $scanner->scan_as_hash;

Do scan and return human readable hash reference which contains information of supported authentication method.

  $sa_hash = { VERSION => { password => 0 or 1, publickey => 0 or 1, },
               VERSION => { password => 0 or 1, publickey => 0 or 1, },
               ... }

  VERSION    : SSH protocol version. 1 or 2.

dump

  $string = $scanner->dump;

Do scan and return as string.
