vboxmanage.exe Problem with Perl

anshumangoyal has asked for the wisdom of the Perl Monks concerning the following question:

I am trying to automate Oracle Virtual Box with Perl. Inside Perl Script I have given some commands to turn on and turn off virtual machine. The program runs fine when executed from command prompt (sitting on the same machine), but when this script is fired from Telnet (Windows Host), the vboxmanage.exe (utility to manage VM's) throws exception. It seems this utility doesnot work over telnet, though this is purely a command line utility (no GUI).

I want to check if there is any way i can execute command inside my perl script, so that it should feel if that is being executed on command prompt only.

Out of curiosity, what are you using as the telnet host on your Windows system? My guess is along the lines of what someone else suggested: the environment that you are connecting to via telnet probably doesn't have something setup correctly. Since you have a script that is working locally, you can probably use something like psexec to remotely run your script remotely from another Windows system. If you are wanting a more Perl type solution and/or the ability to execute your script remotely from other platforms, you could use a Perl module to create your own Telnet server that can accept remote connections and commands. As long as the Telnet server script is started with the correct credentials and environment, you should be good to go. At work, I setup a simple little "Telnet server" using IO::Socket::INET::Daemon that allowed me to remotely connect to a Windows system and get information from a USB connected device to that system. The concepts of what I did there should work in your situation too.	[reply]

What have you tried? How does it fail? Did you have a look at perldoc -f system?	[reply]

It seems this utility doesnot work over telnet, though this is purely a command line utility (no GUI). What error messages do you base that conclusion on? Like every program, it comes down to %ENV, which user the process is running as, user permissions ...	[reply]
