Please do not upload your SSH keys to your slice unless they are 
protected by passphrases; even then, it is not recommended practice. If 
your slice is ever compromised, your key may be stolen and used to gain 
access to all other nodes in your slice. This has happened before and 
will happen again unless users take adequate measures to lock down their 
slices.

A gentle reminder to all users: please change your SSH keys frequently. 
If you ever suspect that a machine, including your desktop, has been 
compromised, change your PlanetLab web password and SSH key from a 
secure location.
