4.3.20 Windows host: port-forwarded SSH connection closed on sleep/wake

[jds]

Windows 8.1 host, Ubuntu 14.04 64-bit guest NAT networking SSH port-forwarded 2222 -> 22

On a Lenovo laptop, on wake after sleep the network connection is reset. Backtracked to 4.3.2, where the connection is not lost.

First, please attach a VBox.log file of such a VM session. Second, just to be sure, you sleep/wakeup the host, not the guest, right?

[jds]

Attached. Yes, it's the host that is sleeping/waking. I'm going to try now with a dev build and with 4.3.10.

[jds]

Confirming that bug occurs with 4.3.10 and with 4.3.21-97963, but NOT with 4.3.2. I will stick to the latter for now.

I'm having difficulty understanding how a network connection from a VM could survive host sleeps... both with NAT and in general. There will be no data exchange with whichever client connected, and to my knowledge the typical (yes, adjustable) timeout is a few minutes.

It works beautifully with 4.3.2.

Any chance of this being addressed in 5.0? I just tried BETA 4 and the ssh connection is still lost over a sleep/wake cycle. Sticking to 4.3.2 since that works.

[jds]

Any sense of whether this is addressed in 5.0?

[Valery Ushakov]

It should be fixed in 4.3.30 and 5.0. Please, give it a try.
