I recently installed a Linux (Mint 17) virtual Machine on a Windows 7 PC. In order to be able to SSH to this virtual machine, I had to define a few rules and redirect ports as explained in other posts of this very forum (see this link for instance).
I realized that there is a known bug on virtual box regarding the drop of TCP connections (see this ticket). After updating the natdnshostresolver1 however, I still experience loss of TCP connections after about 10 to 12 minutes.
The virtualmachine is still on and can still access the internet but it is impossible to ssh to it. From the virtual machine, I can ssh to any other machine, it is only the "input" ssh that is not working.
Does anyone know if this is a known issue with VirtualBox ? I am using version 4.3.20 of the software.
