Machine/justice

Hostnames

• justice.sugarlabs.org
• freedom.sugarlabs.org

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:

• justice-mng.sugarlabs.org
• freedom-mng.sugarlas.org

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 :-(

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.
