is_connected
|
|
logged_in
|
Perl access to the telnet interface on Trango Foxes, SUs and APs. |
Timeout
|
|
);
|
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. |

=item cmd |
|
|
|
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 |
|
|
|
Also accepts these options: |
|
|
|
I<decode> |
|
- if this is true, then it will send the output lines to _decode_lines() and then returns the decoded output |
|
|
|
I<cmd_disconnects> |
|
- if this is true, it then sets logged_in() to false, then it will close() the connection and then sets is_connected() to false |
|
|
|
I<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 |
|
|
|
I<args> |
|
- a string containing the command line options that are passed to the command |

=head1 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. |
