Weird Latency-problem with VRDP?
Posted: 16. Jun 2007, 16:04
I'm currently trying your product and must say i'm quite impressed.
I set up a basic server, created a windows xp sp 1 client and vrdp'ed it's port to 5555 (using the modifyvm option).
If i connect to it with the lan network, there isn't a problem. Everything works perfectly. But when i try to connect to it using an ssh tunnel (putty from a windows guest, tunneling it over the internet from my girlfriends house) it disconnects me with a "network error" on the client.
The logs from the winxp image on the VirtualBox server tell me:
00:00:19.539 VRDP: New connection:
00:00:19.633 VRDP: Channel: [rdpdr] [1004]. Not supported.
00:00:19.633 VRDP: Channel: [cliprdr] [1005]. Accepted.
00:00:19.633 VRDP: Channel: [rdpsnd] [1006]. Accepted.
00:00:19.811 VRDP: Client seems to be MSFT.

00:00:23.057 Guest requests mouse pointer integration
00:00:46.041 VRDP: TCP server failed to send data to the client!!! Disconnecting the client.
00:00:46.254 VRDP: Connection closed:
00:00:46.254 VRDP: Logoff: LAPTOP (127.0.0.1) build 2600. User: [myusername] Domain: [] Reason 0xFFFFFFFF.
00:00:46.255 VBVA: VRDP acceleration has been disabled.
Strangely enough i think it's the VRDP server that seems to kick me because it can't get all the data sent. Can this possibly be the problem?
Bringing down the bandwidth usage in the client (56k modem) doesn't make a difference.
Kind regards,
