RDP freezes on network failure -> Fixed in 2.1.2

[Paul Bailey]

I run VirtualBox on a Ubuntu 7.10 machine with headless RDP. When a user connects and then gets disconnected because of a network failure, the RDP then freezes. If there is only one RDP connection, then it will not let you reconnect. If multiple RDP connections are on, then you get a black screen.

If you disconnect from the RDP normally then everything is fine.

I'm having this problem too with virtualbox 2.0.2

you can see the connection is still open:

VRDP Connection:    active
Clients so far:     12

Client version:     6001
Encryption:         RDP4

Configuration:

VRDP:            enabled (Address 0.0.0.0, Port 3389, MultiConn: on, ReuseSingleConn: off, Authentication type: external)

But the connection is in CLOSE_WAIT:

root@trappen-amv:/data/vbox/.VirtualBox/Machines/windows/Logs# netstat -pant |  grep VBoxHeadless
tcp        0      0 0.0.0.0:3389            0.0.0.0:*               LISTEN      7158/VBoxHeadless
tcp       10      0 192.168.1.200:3389      192.168.1.106:1883      CLOSE_WAIT  7158/VBoxHeadless

The state is CLOSE_WAIT, so it waits for the application to close the connection.

But my multiconn is on, so I should be able to connect to it anyway. Something must be blocking new connections too.

Should be fixed in 2.1.2. Please reopen if the problem persists.

Still happening in 3.0.8
