SSH

[Nathan England]

When you ssh into the machine the second time is the problem, correct? 

If you disconnect all ssh sessions can you then connect again? Or does it give 
the same error?

If you reboot that computer it then lets you ssh in until you do the virtual 
kernel file systems (mount --bind stuff) correct?
