NAME
Device::Router::RTX - interact with Yamaha RTX routers
SYNOPSIS
METHODS
new
my $rtx = Device::Router::RTX->new (
address => '12.34.56.78',
password => 'password',
admin_password => 'administrator password',
);Create a new object for communicating with the router. The IP address of the router is compulsory. If the router has a password set, you also need to supply a password. For some commands, you need to set the administrator password.
This does not open a telnet connection to the router. Use "connect" to open the telnet connection.
connect
$rtx->connect ();Connect to the router. This dies if there is an error. If you need to debug the telnet connection, see the source code of the module which contains extensive debugging code (commented out for the production version).
get_config
$rtx->get_config ("config");Get the router's configuration file and put it into the file config. This uses TFTP (trivial FTP). It dies on error. If you have not set an administrator password in "new" but your router requires one, this will fail with an error "Access violation".
read_config
$rtx->read_config ("config");Read a router configuration file from the specified local file. (This method is not fully functional yet.)
save
$rtx->save ();Save an altered configuration to the router's permanent memory.
command
$rtx->command ($command);Send a command to the router specified by $command, and save it.
wake
$rtx->wake (<LAN>,<MAC>);Send a "wake-on-lan" ("wol") packet to the specified MAC address on the specified LAN (give the number of the LAN, e.g. 1-3 for RTX1000 routers). There is no return value.
arp
my $arp = $rtx->arp();
if ($arp) {
for my $entry (@$arp) {
print "MAC: $entry->{mac} IP: $entry->{ip}.\n";
}
} Read the router's arp table. The return value is the undefined value if the command fails, or an array reference containing hash references if it succeeds. The hash references have four fields, lan (the number of the local area network), ip (the IP address), mac (the MAC address) and ttl (time to live).
TESTING
The default module test does nothing except try to load the module and then exit. There is an extra test in the file <xt/connecting-test.t> which actually tries to connect to the router and do a few things. You can either edit this file to insert the password and IP address of your router, or you can set the following environment variables:
- RTX_ADDRESS
-
Set this to the IP address of your router.
- RTX_PASSWORD
-
Set this to the user password of your router. If the router's password is unset, set this to an empty string.
- RTX_ADMIN_PASSWORD
-
This is the administrator password.
When you run the test and some environment variables are incorrectly set, then run the test again shortly afterwards, or if you run the test when you already have a telnet session open, you may find that the telnet connection is refused. This is a limitation of the device itself, so close all connections, wait for a short time, and try again.
