Are there any linux distros that were meant for headless usage or are all of them capable of being headless. I also would like it if the distro was as non-resource intensive as possible too, any suggestions?
All distros have the same ssh capabilities.
Any distro can be configured very slim, but in general, if you run a distro "headless", so without a DE, there are hardly any resources used. Of all linux applications, DE's usually use the most resources, much more than other applications.
