I have a VPS account on which I set up a Linux server to host some customer websites, and to upload “previews” of websites before publishing them to the production server.

I develop the websites on my own machine (Windows) and do most of the testing there. Because of the difference in platform, sometimes problems appear on the Linux host, and I could use a debugging interface on that…

My question is how safe is it to have xdebug on a remote public server which would also be used for hosting production websites? Is it possible? Recommended? What do you think?

Thanks…

    xdebug is perfectly safe on a remote instance as long as you set the xdebug.remote_host variable. Otherwise it is a MAJOR secuirty problem because it would allow the attacker to view any variable in memory during runtime. It could be used to obtain your mysql login or any other secret variables you may have.

    edit: A VPN is a good solution to keep leaking sensitive data over the net in plain text.
