Before setting up a server at home, it is recommended that you know the [possible limitations imposed by your ISP](/isp). If they are too restrictive, you might consider using a VPN to bypass them.
- A power supply (either an adapter or a MicroUSB cable)
- An ethernet cable (RJ-45) to connect your Raspberry Pi to your router. (Raspberry Pi Zero users can connect the Pi using an OTG cable, Wifi dongle and [following these instructions](https://davidmaitland.me/2015/12/raspberry-pi-zero-headless-setup/))
We do not recommend the manual installation because it is more technical and longer than using the pre-installed image. This documentation is only intended for advanced users.
The latest Rasbpian Jessie image requires a screen and a keyboard, as it is no longer possible to connect directly to the Raspberry through SSH. Nevertheless it is possible to re-enable SSH at boot : before starting your Raspberry, put in the boot partition of the SD card an empty file named `ssh` (without extension).
2. Edit `/etc/ssh/sshd_config` to allow ssh login for root, by replacing `PermitRootLogin without-password` with `PermitRootLogin yes`. Reload the ssh daemon with `service ssh reload`.
