[ClusterLabs] Can fence_vbox ssh-options be configured to use Windows DOS shell?

[Marek Grac]

Hi,

command prompt is start of the line after you login to a machine via ssh.
On my machine it is:

login at hostname:~$

because command prompt depends on shell, settings, ...we are starting ssh
to run shell with predefined command prompt: [EXPECT]$. What does not work
on your system

m,
