There are many ways you can use to copy files to Red Hat server. I will show you my way and I always prefer easy ways.
Download Winscp file transfer software which is free.
After downloading, install it to your computer.
When you open it, choose SCP file protocol and type username and password and click on Login button.
Now you are in. choose / Root
And then go to Preptools folder. On the left side you see your computer and right side preptools folder which has only certificates.ks file we created previous session.
Now you can drag and drop your vcloud director bin file where you saved it into preptools folder.
Last file needs to be copied to prepfolder is libXdmcp-1.0.3-1.el6.x86_64.rpm
It can be downloaded from here http://rpm.pbone.net/index.php3/stat/4/idpl/16002971/dir//com/libXdmcp-1.0.3-1.el6.x86_64.rpm.html
