NAME

Net::Telnet::Trango - Perl extension for accessing the Trango telnet interface

SYNOPSIS

use Net::Telnet::Trango;
my $t = new Net::Telnet::Trango ( Timeout => 5 );

$t->open( Host => $ap ) or die "Error connecting: $!";

$t->login('password') or die "Couldn't log in: $!";

# Do whatever

$t->exit;
$t->close;

DESCRIPTION

Perl access to the telnet interface on Trango APs and SUs.

A handy feature is that it will parse the output from certain commands that is in the format "[key1] value1 [key2] value2" and put those in a hashref that is returned. This makes using the output from things like sysinfo very easy to do.

EXPORT

None

METHODS

new - Creates a new Net::Telnet::Trango object.

new([Options from Net::Telnet,]
    [Decode => 0,]);

Same as new from Net::Telnet but sets the default Trango Prompt: '/#> *$/'

It also takes an optional parameter 'Decode'. If not defined it defaults to 1, if it is set to 0, it will not decode the output and instead return a reference to an array of the lines that were returned from the command.

ACCESSORS

These are usually only set internally.

firmware_version - returns the firmware version

Returns the firmware version if available, otherwise undef.

It should be available after a successful open().

host_type - return the type of host you are connected to.

returns the type of host from the login banner for example M5830S or M5300S.

Should be available after a successful open().

is_connected - Status of the connection to host.

returns 1 when connected, undef otherwise.

logged_in - Status of being logged in to the host.

returns 1 after a successful login(), 0 if it failed and undef if login() was never called.

login_banner - The banner when first connecting to the host.

returns the banner that is displayed when first connected at login. Only set after a successful open().

last_lines - The last lines of output from the last cmd().

returns, as an array ref, the output from the last cmd() that was run.

last_error - A text output of the last error that was encountered.

returns the last error reported. Probably contains the last entry in last_lines.

ALIASES

bye - alias of exit()

Does the same as exit()

restart - alias of reboot()

Does the same as reboot()

save_systemsetting - alias of save_ss()

Does the same as save_ss()

COMMANDS

Most of these are just shortcuts to cmd(String => METHOD), as such they accept the same options as cmd(). Specifically they take a named paramater "args", for example: tftpd(args => 'on') would enable tftpd

tftpd - The output from the tftpd command

Returns a hash ref of the decoded output from the command.

Also see enable_tftpd() and disable_tftpd() as those check that it was successfully changed.

ver - The output from the ver command

Returns a hash ref of the decoded output from the command.

sysinfo - The output from the sysinfo command

Returns a hash ref of the decoded output from the command.

exit - Exits the connection

exits the command session with the Trango and closes the connection

reboot - Sends a reboot command

reboots the Trango and closes the connection

remarks - Set or retrieve the remarks.

Takes an optional argument, which sets the remarks. If there is no argument, returns the current remarks.

my $old_remarks = $t->remarks();
$t->remarks($new_remarks);

sulog - The output from the sulog command

Returns an array ref of hashes containing each log line.

save_sudb - saves the sudb

Returns true on success, undef on failure

syslog - The output from the sulog command

Returns a hashref of the output from the syslog command

pipe - the pipe command

Returns the output from the pipe command

maclist - retrieves the maclist

Returns the output from the maclist command

maclist_reset - resets the maclist.

No useful output.

Returns the output from the eth link command

This command seems to cause some weird issues. It often will cause the command after it to appear to fail. I am not sure why.

su_info - gets the su info

Returns information about the SU.

You need to pass in the $suid and it will return the info for that suid.

$t->su_info($suid);
$t->su_testrflink($suid|'all');

save_ss - saves the config.

Returns 1 on success, undef on failure.

opmode - sets opmode ap y or returns the opmode

$t->opmode([ap y]);

open - Open a connection to a Trango AP.

Calls Net::Telnet::open() then makes sure you get a password prompt so you are ready to login() and parses the login banner so you can get host_type() and firmware_version()

login - Login to the AP.

Calls open() if not already connected, then sends the password and sets logged_in() if successful

parse_login_banner - Converts the login_banner to something useful.

Takes a login banner (what you get when you first connect to the Trango) or reads what is already in login_banner() then parses it and sets host_type() and firmware_version() as well as login_banner()

su_password - Set the password on SUs connected to the AP.

su_password('new_password'[, 'suid']) If no suid is specified, the default is "all".

$t->su_password('good_pass', 5);

su_ipconfig - Change IP configuration on SUs connected to the AP.

su_ipconfig( 'suid', 'new_ip', 'new_subnet', 'new_gateway' )

$t->su_ipconfig( 5, '10.0.1.5', '255.255.255.0', '10.0.1.1' );

sudb_view - Returns the output from the sudb view command

returns a reference to an array of hashes each containing these keys 'suid', 'type', 'cir', 'mir' and 'mac'

sudb_add - Adds an su to the sudb

Takes the following paramaters

suid : numeric,
type : (reg|pr)
cir  : numeric,
mir  : numeric,
mac  : Almost any format, it will be reformatted,

and returns true on success or undef otherwise.

$t->sudb_add($suid, 'reg', $cir, $mir, $mac);

You should save_sudb() after calling this, or your changes will be lost when the AP is rebooted.

sudb_delete - removes an su from the sudb

Takes either 'all' or the suid of the su to delete and returns true on success or undef otherwise.

$t->sudb_delete($suid);

You should save_sudb() after calling this, or your changes will be lost when the AP is rebooted.

sudb_modify - changes the su information in the sudb

Takes either the suid of the su to change as well as what you are changing, either "cir, mir or su2su" and returns true on success or undef otherwise.

cir and mir also take a value to set the cir/mir to.

su2su takes a group id parameter that is in hex.

$t->sudb_modify($suid, 'cir', 512);

You should save_sudb() after calling this, or your changes will be lost when the AP is rebooted.

enable_tftpd - enable the TFTP server

runs tftpd(args => 'on') and makes sure that Tftpd is now 'listen'ing

disable_tftpd - disable the TFTP server

runs tftpd(args => 'off') and makes sure that Tftpd is now 'disabled'

cmd - runs a command on the AP.

This does most of the work. At the heart, it calls Net::Telnet::cmd() but it also does some special stuff for Trango.

Normally returns the last lines from from the command

If you are using this, rather than one of the "easy" methods above, you probably want to read through the source of this module to see how some of the other commands are called.

In addition to the Net::Telnet::cmd() options, it also accepts these:

decode - if this is true, then it will send the output lines to _decode_lines() and then returns the decoded output

no_prompt - if this is true, it does not wait for a prompt, so you are not stuck waiting for something that will never happen.

cmd_disconnects - if this is true, it then sets logged_in() to false, then it will close() the connection and set is_connected() to false

expect - if this is set (usually to 'Success.') it will check for that in the last line of output and if it does not, will return undef because the command probably failed

args - a string containing the command line options that are passed to the command

$t->cmd( String => 'exit', no_prompt => 1, cmd_disconnects => 1 );

TODO

There are still a lot of commands that are not accessed directly. If you call them (as cmd("command + args") or whatever) and it works, please send me examples that work and I will try to get it incorporated into the next version of the script.

I also want to be able to parse the different types of output from commands like su, sudb all and anything else that would be better available as a perl datastructure.
