Transferring files between two computers using php

legend986

I have a small file to be transferred between two computers every few
seconds. I'm using unix with a bare bones version of php, i.e. just the
original thing that gets installed when I run "yum install php". As there is
no webserver on any of these machines, I was wondering if there is a way to
transfer a small file between them and if there is, could someone be kind
enough to provide me with an example please?

What I have:
Basic CLI version of PHP 5.0
SSH Access

What I don't have:
Webserver

If they are on the same LAN, you could just use PHP's basic file functions. If not but if FTP is enabled, you could use PHP's [man]FTP[/man] functions.

Well, we need an ftp server for that right... The systems don't have that either 🙁 And no, the systems do not belong to the same LAN...

Are you sure there's no FTP server (it's a pretty standard part of any UNIX installation)? If not, how do you currently get files onto the servers?

I'm sorry. I realized something just now. I have three computers A, B and C. To login to B and C I should use A because it has a SSH key. I don't have any other way of accessing these two computers. Now, if I need to transfer a file between B and C, I am unable to find a way that would work... because I don't know how to authenticate without SSH keys...
