- Why system reports "permission denied on key" while setting the kernel parameter
# sysctl -w net.ipv4.conf.all.mc_forwarding=1 error: "Permission denied" setting key "net.ipv4.conf.all.mc_forwarding" # echo 1 > /proc/sys/net/ipv4/conf/all/mc_forwarding bash: /proc/sys/net/ipv4/conf/all/mc_forwarding: Permission denied
- Setting net.ipv4.conf.all.mc_forwarding to zero is failing with the following message:
-- Unit systemd-sysctl.service has begun starting up.
