As the title says I would like to know if it is possible to limit bandwidth (download and upload) of OpenVZ container (from inside it) without use of tc or any additional kernel driver (VPS provider does not support it).
I can enable TUN/TAP interfaces in the VPS, can it be used to locally shape the traffic in both directions (total bandwidth is limited, I cannot simply do the shaping somewhere else)? I looked at OpenVPN, but it seems that only one direction can be shaped and also I'm not entirely sure how to setup routing to make it working.
PS: For my purpose I cannot use trickle or proxy. The application I want to be limited doesn't allow setting proxy and runs in multiple processes so trickle can't handle it.
