Logging in from the Internet

ssh extuser@haamster.rice.edu

(Note that everybody uses the extuser name at this stage--do not substitute your own user name.)

You should see a banner message and then a prompt:

extuser@OpenWrt:~$ 

Then type

./wake MACHINE_NAME

Once this tells you that you're good to go, you may SSH onward using your assigned user name. (It may yet take another minute until the machine is fully up and responding to SSH.)

For example:

ssh MYUSERNAME@box

More than likely, this won't work, because we won't have told you your password (with the intention that you'll just use your SSH key). To make login work, copy the following snippet into your $HOME/.ssh/config:

Host haamster
  User extuser
  HostName haamster.rice.edu
Host box
  ProxyCommand ssh haamster nc box 22
  User YOUR_USER_NAME
Host slate
  ProxyCommand ssh haamster nc slate 22
  User YOUR_USER_NAME

Make sure to substitute in your user name for YOUR_USER_NAME. You should then (after waking the machine) be able to simply log in by saying

ssh box

on your machine. (NOT on haamster)

Keeping a machine awake
