Hardware and Information gathering

Now you can get information of the servers hardware and configuration.

⁠use Rex::Hardware;
⁠use Data::Dumper;
⁠
⁠desc "Get Hardware Information";
⁠task "hw-info", "testsystem", sub {
⁠    my %hw = Rex::Hardware->get(qw/ Host Kernel Memory Network Swap /);
⁠
⁠    print Dumper( \%hw );
⁠};

Will produce the following example output:

⁠$VAR1 = {
⁠    'Network' => {
⁠        'networkdevices'       => [ 'eth0', 'wlan0' ],
⁠        'networkconfiguration' => {
⁠            'wlan0' => {
⁠                'broadcast' => '192.168.2.255',
⁠                'ip'        => '192.168.2.229',
⁠                'netmask'   => '255.255.255.0',
⁠                'mac'       => '00:21:5C:5C:1E:5F'
⁠            },
⁠            'eth0' => {
⁠                'broadcast' => undef,
⁠                'ip'        => undef,
⁠                'netmask'   => undef,
⁠                'mac'       => '00:1C:25:94:B0:85'
⁠            }
⁠        }
⁠    },
⁠    'Memory' => {
⁠        'shared'  => '0',
⁠        'buffers' => '36',
⁠        'free'    => '3168',
⁠        'used'    => '792',
⁠        'total'   => '3961',
⁠        'cached'  => '407'
⁠    },
⁠    'Kernel' => {
⁠        'kernelversion' => '#1 SMP PREEMPT 2011-02-21 10:34:10 +0100',
⁠        'architecture'  => 'x86_64',
⁠        'kernel'        => 'Linux',
⁠        'kernelrelease' => '2.6.37.1-1.2-desktop'
⁠    },
⁠    'Swap' => {
⁠        'free'  => '3812',
⁠        'used'  => '0',
⁠        'total' => '3812'
⁠    },
⁠    'Host' => {
⁠        'domain'                 => 'site',
⁠        'manufacturer'           => 'LENOVO',
⁠        'hostname'               => 'linux-ymf0.site',
⁠        'operatingsystemrelease' => '11.4',
⁠        'operatingsystem'        => 'SuSE'
⁠    }
⁠};

Install Packages

Support for apt, yum and zypper (OpenSuSE)

Example:

⁠# include for ,,install'' Function
⁠use Rex::Commands::Pkg;
⁠
⁠# include for ,,operating_system_is'' Function
⁠use Rex::Commands::Gather;
⁠
⁠user "root";
⁠
⁠private_key "/Users/jan/.ssh/id_rsa";
⁠public_key "/Users/jan/.ssh/is_rsa.pub";
⁠
⁠# group servers
⁠group "test" => "debian01", "centos01", "suse01";
⁠
⁠# run tasks in parallel
⁠parallelism 2;
⁠
⁠desc "Prepare System";
⁠task "prepare",
⁠  group => "test",
⁠  sub {
⁠
⁠    # check if operating system is CentOS, because on CentOS vim is
⁠    # available through the package "vim-enhanced".
⁠    if ( operating_system_is("CentOS") ) {
⁠        install package => "vim-enhanced";
⁠    }
⁠    else {
⁠        install package => "vim";
⁠    }
⁠
⁠    install package => "mc";
⁠
⁠  };

This task will install vim and mc on all the 3 systems.
