in reply to Can I execute scripts remotely using Perl sockets in Windows?

Do you have a DMZ? Do you have a firewall? Do you have control over these, if they exist? Remote as in across the Internet? Remote as in across the local LAN?

A server will listen on a specific port for connections. You can write a server in Perl and there are plenty of examples. Use Super Search. In order to connect to this server remotely you need to be able to 'SEE' this port from the remote machine. Lets assume no firewall, and across Internet: 

Win32 Server on 1.2.3.4  <------- connect 1.2.3.4:8080

As soon as you add firewalls you need to have two things occur. You need to map from the external IP the intenal IP and allow connections on the target port: 

Server 10.0.0.1 <--- DMZ/FW 1.2.3.4 <----- connect 1.2.3.4:8080

[download]

It's anyone's guess if you will be able to connect through a firewall/DMZ. Not unless it is specifically configured to allow it in all liklihood.

What is it you need to remotely execute. There may well be a pre written solution to your problems.....

    There are some nightly batch jobs that run in some machines. There might be a situation that I have to manually run the batch during the day. That was why I was thinking of using perl socket-server module that would help.

    Most of the machines are in the network.. One or two of the machines are main servers, so they might contain a firewall.

    Are there pre-written solutions for the above?
    Thanks.

      You don't need perl for this. It is easy to remotely exec stuff on Win32 machines within a network (provided we are talking NT/2000/XP). Here is a pre-rolled shareware solution that worked last time I looked: RemoteExec

      Internal network servers are unlikely to be firewalled off (Win32 depends on all sort of ports being open to function), although you may of course have permissions issues.

      If they do contain firewalls, you are probably going to run into problems. I have got a similar problem before where the firewall allowed checking of email enabled, so wrote a script to check a particular pop email account every 1/2 hour or so. If I wanted to do something I would just email a specially formatted email to the address and the program would pick it up and do its job. Not the safest way of doing things perhaps, but a good work around for me. Regards, Gerard

        Use Remote Desktop connection, install the client on your machine and then connect to whatever server you need to execute the programs on.
