Host networking influenced by VBox
Posted: 25. May 2009, 15:34
Hi Folks!
Problem on WinXP/SP3 host, same with MS Vista Business 32 Bit/SP1: After installing VBox 2.2.2, the Dell 1600n print driver does'nt work anymore. The same is true for the Dell Network Scan. The Network Scan driver simply does not find the printer/scanner.
De-installing VBox leads to a working print/scan setup. Thus, I can say, that the inserted network module of virtual box is not totally transparent.
Setup: A switched network with two Windows PCs, each running WireShark. The system with VBox has an additional Host-Only Network.
Abstract: When searching for a printer/scanner, the dell software broadcasts an UDP Packet with the source address of the host, destination address=255.255.255.255, UDP Port 1124.
1. Searching for the printer when VBox is NOT installed: the UDP-Packet is seen on the host running VBox, and the Printer correctly responds.
2. Searching for the printer when VBox IS installed: the UDP Packet is sent on the physical network interface with the source IP address of the Host-Only-Network
3. Disabeling the Host-Only-Network in the Windows Network Setup let's the UDP Packet vanish in whole.
4. De-Installing the VBox Host-Only Network Card does not help at all.
Is there anything more I can to do isolate the problem?
