"I think another thing we might want to learn about is how to sound the alarm when the break glass is used. Is there an easy way of doing that with SSH?" Yes - quite simple and old-fashioned, actually ... I have this line in the SSH users' .login file: /usr/local/sbin/sms 4153331111 4158882222 "USER LOGIN TO XXX - $DATE" >& /dev/null ... where the 'sms' command, above, is a shell script I wrote to call twilio messaging with the curl command. A very simple example of that would be: curl -X POST -d "Body=$msg" -d "From=$from" -d "To=$to" "https://api.twilio.com/2010-04-01/Accounts/$accountsid/Messages" -u "$accountsid:$authtoken" ... and this works like a charm. Alternatively, you could rick-roll your on-call sysadmin: /usr/local/bin/curl -XPOST https://api.twilio.com/2010-04-01/Accounts/$accountsid/Calls.json --data-urlencode "To=$number" --data-urlencode "From=$callerid" --data-urlencode "Url=http://demo.twilio.com/docs/voice.xml" -u $accountsid:$authtoken (the voice.xml demo is, in fact, Rick Astley)
