Info
Freedom and Justice are two twin KVM hosts bought by Sugar Labs in 2012.
Justice is currently our primary VM hosting box, while freedom is a hot-standby running some secondary services in docker containers and backups.
Machines
The following machines services are hosted:
- Machine/lightwave, Service/Nameservers,
- Machine/pootle, Service/translate,
- Service/activities aslo,
- Machine/library,
- Machine/aslo4,
- Machine/jita, Service/git, Service/jabber, Service/meeting, Service/obs, Service/chat, Service/cgit, Service/blacklist, Service/stats,
Hardware
- 2U rack-mountable case
- Motherboard Supermicro H8SGL (or maybe H8SGL-F)
- 8-core Opteron 6212 @ 1.7GHz
- 64GB RAM
- 2x1TB RAID1
Management
The two servers have SMT management cards from Supermicro with a seriously awful web interface:
Of course you need a separate account. Full KVM support requires the Java browser plugin (yuck!), so we mostly use them for the big reset button in case a server hangs (it happened about once per year).
Use a long, unguessable password, but not one you're also using elsewhere! A few years ago, a backdoor was discovered in this firmware which would reveal all passwords in plaintext with a simple telnet! Also, login uses unencrypted http.
It's also possible to talk to the management card from Linux using ipmitool.
Both cards are running firmware version 3.16, which patched a huge backdoor that would trivially reveal all passwords in plaintext. No kidding. There's a newer firmware version, but attempts to update to it failed with both Chrome and Firefox (error: "413 - Request Entity Too Large"). I suspect a bug in their http POST implementation :-(
Software
- Justice: Ubuntu 18.04 LTS Bionic
- Freedom: Ubuntu 18.04 LTS Bionic
Location
Hosted by the MIT Media Lab in server room E15-243.

Network configuration
Justice is globally accessible through public, static IPv4. The IPv6 /64 subnet (6to4) is currently experimental and not associated with AAAA records.
Hosted VMs
All KVM virtual machines are managed by libvirtd.
See Sysadmin/Add virtual machine for creating new VMs.
