[Planetlab-users] Problem with SSH in nodes.

[hdiakos at csd.uoc.gr]

Ok, thanks!!! I'll look into it with planetlab.eu support.
One note: I have used that guide and verified that my key is in a  
correct format. I also verified with nmap that port 22 is open for ssh  
but still I am not allowed to enter in some nodes for an inexplicable  
reason. It's funny :P.

Anyway, thanks for your assistance! :)
