Rebooting the production morph.io server

1. Log into Linode and go to the page for morph.io
2. Go to the Remote Access tab and to Console Access at the bottom of that page
3. There’s a command there called ‘Lish via SSH’
4. Copy that to your local shell and run it. You should now see the output of the machine, processes running, dying etc.
5. In another shell session ssh to root@morph.io
6. Try the light touch first, run reboot there
   • If you switch to the lish session, you will see processes start shutting down in the linode console access session

• after a minute that may become stuck on a command
