sure? sysctl does not report them>
linux-5jrm:/ # sysctl net.ipv4.tcp_available_congestion_control
net.ipv4.tcp_available_congestion_control = cubic reno

oh and i also need them for xubuntu, can you help me with that, too?
Hi
You will need to add them to the modules to load at boot
in /etc/sysconfig/kernel.
/sbin/sysctl net.ipv4.tcp_available_congestion_control
net.ipv4.tcp_available_congestion_control = cubic reno
modprobe tcp_vegas
modprobe tcp_westwood
/sbin/sysctl net.ipv4.tcp_available_congestion_control
net.ipv4.tcp_available_congestion_control = cubic reno vegas westwood
I’m guessing you need to do the same sort of thing in ubuntu as well,
not sure where though

big thx, i didnt thought about probing them, i thought they were loaded by their simple appearance in some folder/config by sysctl.
it worked out, westwood is great with my neighbours crumpy wlan!
just the xubuntu thing left, then. i’ll try!
