User Information
Note: some of these URLs might change as the migration finishes, basically iron.waffle.tech is just a temporary way to get to the new machine and will be replaced by just waffle.tech once the main webserver is totally moved over.
Services
- Account management: (e.g. password changes) id.waffle.tech
- Virtual machines: (available on request as it's a bit more complicated to set up users): vm.waffle.tech
Shell
SSH to login.waffle.tech.
Incidentally, login.waffle.tech is special as it has complete direct access from the internet. This allows you to run various things like game servers and have them be accessible from the internet via the hostname login.waffle.tech. Generally speaking, all other machines are behind a restrictive firewall and usually also NAT due to IPv4 addresses being hard to get in any two-digit quantity.
When connected to login.waffle.tech, run 'kinit' and log into Kerberos to allow convenient no-auth SSH to other waffle.tech machines.
Basic platform info
The new waffle.tech (read in the same voice as New Coke) is a single physical machine with dual 4-core Xeons (with HT), 128 GB RAM, 1TB of moderate performance (for SSDs) solid-state storage mirrored for redundancy, and 4TB of spinning platter storage also mirrored for redundancy. It is located in a shared rack in a mid-tier data center in Las Vegas, NV. The internet connection is very fast but is capped at tens of TB of transfer per month.
The basic platform is the open-source enterprise virtualization engine Proxmox. Most virtual machines run CentOS 8, but login.waffle.tech runs Fedora Server 32 to offer more recent versions. Access control is centralized by FreeIPA and, soon, Keycloak for SAML and oauth. All virtual machines share an internal network in reserved IP space, and the VM host forwards connections on many ports to various VMs. Some VMs (such as login) have an additional network interface which is directly on the internet with a public IP.
