This is a client/server setup. Your machine is a client, the server software for that client needs to be available on the remote side:

• ftp -> ftpd
• scp -> sshd
• uuencode + telnet -> telnetd + uudecode
• cp/copy -> smbd or other CIFS server
• stick drive -> a pair of sneakers and an available USB port
• ...

If you need to install software on the remote machines and they are windows machines and you have the appropriate authorization on the remote machines, you can push a windows installation package to that machine.

You need to have something on the remote side to talk to. The type of access (permissions + protocol) you have on the remote side will determine how you are able to transfer the files to the remote machine. Some of them can be driven by Perl, others cannot.
