[Planetlab-users] Problem with SSH in nodes.

[hdiakos at csd.uoc.gr]

Hello to all and Happy New Year :).

Now to the point :D.
Well, yes I looked into it but still there are machines (like  
planetlab1.ics.forth.gr) that while in a boot state they still
refuse to let me in. I understand it if that happens from a node which
belongs to PLC since we belong to PLE but still machines in the PLE network
refuse to accept my ssh key for some reason. The only workaround thus  
far seems
to be to try and filter those "problematic" nodes but it's a pity we can't do
some work on them anymore :/

-hdiakos
