Kernel parameters

How can I tweak these kernel parameters?

rmem_default
rmem_max
wmem_default
wmem_max

Would they be specified as

kernel.rmem... ??

in sysctl.cfg?

Thanks

Not quite. You can find the variables in /proc/sys/net/core. Starting in
/proc/sys, replace all slashes with periods. The names for sysctl are
therefore:

net.core.rmem_default
net.core.rmem_max
net.core.wmem_default
net.core.wmem_max
