new ssh keys for HPs, lab.cs.swarthmore.edu

We changed the ssh keys for the HPs in our main lab, so now you should be able to just type ssh lab.cs.swarthmore.edu if you don't care which lab machine you get. If you do care, you can still ssh to a particular machine (e.g., ssh lime).

Here are the names of the HPs: almond caper caraway cayenne celery coconut gale hyssop lavender lemon licorice lime marjoram mugwort olive onion poppy sesame sumac tamarind.

Because we changed these keys, you may get a big warning message the next time you try to connect to one of these machines (see below). The new fingerprints for the keys are as follows:

 e2:f5:5c:b1:b8:5d:98:4d:99:34:c5:29:56:e1:95:67 /etc/ssh/ssh_host_rsa_key.pub
 72:14:44:36:46:fc:e7:3b:b3:31:7e:6f:c7:f6:67:09 /etc/ssh/ssh_host_dsa_key.pub

In the warning message below, the correct rsa key fingerprint above is listed, so it would be OK for me to follow the warning's instructions (in this case, I need to delete the offending/old key from my ~/.ssh/known_hosts file). Please let us know if you see a different fingerprint, or if you have questions or need help with this.

$ ssh olive
