Perl telnet script

Hi, I need a custom PERL script that opens a telnet connection to another application, executes a command and interpretes the result. The first line in the script should be #!/path/to/perl -w followed by use strict;. Clean and good code is therefore required and warnings about uninitialized variables or else are not accepted. The script has to run on CentOS 5.5 which comes with an older version of perl which is 5.8.8. Only the use of one addtional module is allowed which is Net::Telnet (Version 3.03-5) as available on CentOS 5.5. The script shall take three command line parameters: ip, port and common_name It establishes the connection to ip and port and sends the command "kill <common_name>". The resulting line gets interpreted. If the connection with the identifier <common_name> could be killed by the remote service you give back the exit code 0, if you couldn't connect via telnet the code 1, if the connection couldn't be killed 2, if the result of your command times out 3. The remote application that is contacted via telnet is the openvpn management console. Examples: Common name found, connection killed (example with telnet client): ##################################################################### [TEST]tunnel1 etc # telnet localhost 4242 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. INFO:OpenVPN Management Interface Version 1 -- type 'help' for more info kill sgloeckner SUCCESS: common name 'sgloeckner' found, 1 client(s) killed quit Connection closed by foreign host. ##################################################################### Common name not found, connection not killed (example with telnet client): ##################################################################### [TEST]tunnel1 etc # telnet localhost 4242 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. INFO:OpenVPN Management Interface Version 1 -- type 'help' for more info kill sgloeckner ERROR: common name 'sgloeckner' not found quit Connection closed by foreign host. ##################################################################### As in all our biddings - since we're an incorporated german company - the service provider has to be able to issue a valid invoice for his work - either with local tax payer id or vat code (if it's a company).
