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

13: =head1 SYNOPSIS
14:
15: use Net::Telnet::Trango;
1.3 andrew 16: my $t = new Net::Telnet::Trango ( Timeout => 5 );
1.2 andrew 17:
1.6 ! andrew 18: $t->open( Host => $fox ) or die "Error connecting: $!";
1.2 andrew 19:
20: $t->login('password') or die "Couldn't log in: $!";
21:
22: # Do whatever
23:
24: $t->exit;
25: $t->close;
26:
27: =head1 DESCRIPTION
28:
29: Perl access to the telnet interface on Trango Foxes, SUs and APs.
30:
31: Another 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.

214:
215: Most of these are just shortcuts to C<cmd(String =E<gt> METHOD)>, as such they accept the same options as C<cmd()>. Specifically they take a named paramater "args", for example:
216: C<tftpd(args =E<gt> 'on')> would enable tftpd

219:
220: =item tftpd
221:
222: Returns a hash ref of the decoded output from the command.

227:
228: Returns a hash ref of the decoded output from the command.

900: =head1 TODO
901:
902: 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.
903:
904: 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.
