cgroup socket(PF_NETLINK, SOCK_DGRAM, 11) = -1 EPROTONOSUPPORT

Hi,
I use custom linux kernel v.2.6.37 with debian squeeze.
I need to make cgroup-bin package work properly.
When I start:
/etc/init.d/cgconfig start
it's ok.
But /etc/init.d/cgred doesn't start ok (I mean there is no error output to console but daemon /usr/sbin/cgrulesengd exits).
I started it with strace and got this:
# strace /usr/sbin/cgrulesengd -n

I guess I missed something when configuring kernel because under vanilla kernel cgroup works fine.

cnxsoft · 12-14-2011, 07:14 AM

You need to enable NETLINK in the kernel.

CONFIG_NETLINK=Y

olexandr.klymenko · 12-14-2011, 07:34 AM

I'm afraid not:
CONFIG_CONNECTOR=y
