required to install opennebula.

check your shebang line, it should be
"#! <path_to_your_ruby VM i.e. /usr/bin/ruby>"

Not necessarily. The env is a standard way of invoking ruby with the
current environment settings intact.

#!/usr/bin/env ruby

should work as is, provided you have ruby installed in a way that your
environment is aware of. It is the most portable of writing a script header
in ruby, as it should work across all *nix systems that way.

For the OP, I have no idea what opennebula is. If it is some sort of VM or
VPS thing, you may need to install ruby to begin with, but I have no idea
what's required to do so.

Well, that's a good place to start: http://support.suso.com/supki/SSH_Tutorial_for_Linux

ps. The command 'ping -c 1 onehost' might give you the answer in plain English.

Thanks in advance

On a terminal, try

/usr/bin/evn ruby
echo $?

127 -- it could not find ruby, check your $PATH or, specify the full_path_to_ruby
126 -- couldn't start, check with you system administrator to see is there any restriction, e.g. SELINUX

Hi,

mind you, that's not a ruby related problem at all.

From 192.168.116.59 icmp_seq=1 Destination Host Unreachable

Learn to use a search engine, namely 'Google', to find solutions to errors. Google gives this a third link (iirc) What Does Destination Host Unreachable Mean? which explains what this error is.
