App::ClusterSSH::Host(3pm)				User Contributed Perl Documentation				App::ClusterSSH::Host(3pm)

NAME
ClusterSSH::Host - Object representing a host. SYNOPSIS
use ClusterSSH::Host; my $host = ClusterSSH::Host->new({ hostname => 'hostname', }); my $host = ClusterSSH::Host->parse_host_string('username@hostname:1234'); DESCRIPTION
Object representing a host. Include details to contact the host such as hostname/ipaddress, username and port. METHODS
$host=ClusterSSH::Host->new ({ hostname => 'hostname' }) Create a new host object. 'hostname' is a required arg, 'username' and 'port' are optional. Raises exception if an error occurs. $host->get_hostname $host->get_username $host->get_port $host->get_master Return specific details about the host $host->set_username $host->set_port $host->set_master Set specific details about the host after its been created. get_realname If the server name provided is not an IP address (either IPv4 or IPv6) attempt to resolve it and retun the discovered names. get_givenname Alias to get_hostname, for use when " get_realname " might return something different parse_host_string Given a host string, returns a host object. Parses hosts such as check_ssh_hostname Check the objects hostname to see whether or not it may be configured within the users $HOME/.ssh/config configuration file host 192.168.0.1 user@host user@192.168.0.1 host:port [1234:1234:1234::4567]:port 1234:1234:1234::4567 and so on. Cope with IPv4 and IPv6 addresses - raises a warning if the IPv6 address is ambiguous (i.e. in the last example, is the 4567 part of the IPv6 address or a port definition?) and assumes it is part of address. Use brackets to avoid seeing warning. AUTHOR
