== Management ==
The two servers have SMT management cards from Supermicro with a seriously awful web interface:
* [http://justice-mng.sugarlabs.org/ justice-mng.sugarlabs.org]
* [http://freedom-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 [https://www.supermicro.com/support/resources/bios_ipmi.php?vendor=2&keywords=H8S 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 :-(
