I have a network of OpenVZ machines that I am testing various congestion control methods on. I need to know how to change the congestion control. Currently I get nothing but permission denied. Is it even possible to change this on this sort of configuration?
[tylersc@center ~]$ sudo sysctl -w net.ipv4.tcp_congestion_control=reno error: permission denied on key 'net.ipv4.tcp_congestion_control' [tylersc@center ~]$ sudo sysctl net.ipv4.tcp_congestion_control net.ipv4.tcp_congestion_control = cubic
Correction: OpenVZ not OpenVM
