On boss.utah.geniracks.net, i see:

• Per /etc/master.passwd, root's password is not locked
• Per /etc/ssh/sshd_config, root is permitted to do password-based remote login

For machines which have public IPs, remote users (particularly root) should be restricted to login via public keys, to reduce the risk from SSH password-guessing attacks.

I have created several slivers in the last couple of weeks where one or more of the four nodes (VMs) have not had their SSH keys configured correctly. IOW, I get a password prompt when attempting to log in to the node. I ran into the same problem today and left the slice up in case someone wants to troubleshoot. The slice is johGEM1209261101. I can only log into node PCA (pc1.utah.geniracks.net -p 31035). The rest present the password prompt.

Luisa has reproduced the same problem in two of her slices today.

Hello,

I am executing the InstaGENI Acceptance tests and need to upload
two Ubuntu images to be used in experiments on the InstaGENI rack at Utah.

Please let me know if there are any special requirements  that I should
consider in creating the Ubuntu images.  I plan to run one Ubuntu image with
"emulab-openvz" and one Ubuntu with "raw-pc" type.

Also, if any documentation already exists that I should reference, please let me know.

Luisa
