So you want to give us hardware? Great! Here's what we need...
Physical hardware requirements
If you want to donate hardware, there are specific requirements for machine we manage that you should follow. For other donations, please see the donation site.
This list is not final, and if you have questions, please contact us. Also note that we also accept virtual machine "donations" now, for which requirements are different, see below.
Must have
- Out of band management with dedicated network port, preferably a something standard (like serial-over-ssh, with BIOS redirection), or failing that, serial console and networked power bars
- No human intervention to power on or reboot
- Warranty or post-warranty hardware support, preferably provided by the sponsor
- Under the 'ownership' of Tor, although long-term loans can also work
- Rescue system (PXE bootable OS or remotely loadable ISO image)
Nice to have
- Production quality rather than pre-production hardware
- Support for multiple drives (so we can do RAID) although this can be waived for disposable servers like build boxes
- Hosting for the machine: we do not run our own data centers or rack, so it would be preferable if you can also find a hosting location for the machine, ideally dual-stack (IPv4 and IPv6) and gigabit or greater
To avoid
- proprietary Java/ActiveX remote consoles
- hardware RAID, unless supported with open drivers in the mainline Linux kernel and userland utilities
Virtual machines requirements
Must have
Without those, we will have to be basically convinced to accept those machines:
- Debian OS
- Shell access (over SSH)
- Unattended reboots or upgrades
The latter might require more explanations. It means the machine can be rebooted without intervention of an operator. It seems trivial, but some setups make that difficult. This is essential so that we can apply Linux kernel upgrades. Alternatively, manual reboots are acceptable if such security upgrades are automatically applied.
Nice to have
Those we would have in an ideal world, but are not deal breakers:
- Full disk encryption
- Rescue OS boot to install our own OS
- Remote console
- Provisioning API (cloud-init, OpenStack, etc)
- Reverse DNS
- Real IP address (no NAT)
To avoid
Those are basically deal breakers, but we have been known to accept those situations as well, in extreme cases:
- No control over the running kernel
- Proprietary drivers
