clipboard issue

[Stefan]

Dear all, i'd like to mention an issue which I found today :

scenario : 2 computers, 1 workstation, 1 notebook. workstation is hosting Server 2003 sbs, 2 ubuntu server based on virtualBox. Currently I am working on that workstation and I am connected through vpn client to a customers network, where I access Citrix XenApp. My notebook is in the same network as my workstation, but other than that, no direct tcp connection. (exception : accessing rdp session from my notebook to my virtual sbs server) However following happens : my notebook is connected to server 2003 via rdp. My workstation is just hosting these. On my notebook : if I copy something to clipboard, I can access it from my workstation. And also I could access it from citrix XenApp, connected through vpn. I just had the rdp session the the vServer open. Nothing else. Not performing any common stuff with my workstation.

If I disable clipboardsharing from my notebook to rdp session, I can't copy & paste text to my server - this works.

However, If I open notepad in my server, and put some text in it, then copy it via ctrl+c,

I can access the servers clipboard from my workstation. But it is just hosting this. Remote Control in VirtualBox is disabled, and I just opened notepad in a rdp session from my notebook - not from my workstation which hosts the server.

Furthermore this clipboard stuff is also accessible via Citrix XenApp, cause there my clipboard is shared again.

Question now is, how can it be, that my workstation which just hosts my virtualServer has clipboard text from the server, without having a direct connection to it?

I hope that I described this topic understandable. If not, please do not hesitate to ask.
