No, but there's no need to. You can write it, but you can't read it. It's a "trigger file":

/proc/sys/net/ipv4/route/flush
Writing to this file results in a flush of the routing cache.

oh i understand now the error in his screenshot was because of his grep
i was thinking he got those errors because the script itself was trying to access those files that was why i was asking if we could give it chmod 644 access instead

That means no one can read the content of this file, even 'root'. That's why you get

sysctl: error reading key 'net.ipv6.route.flush': Permission denied
sysctl: error reading key 'net.ipv4.route.flush': Permission denied

sysctl tries to read it, but it can't.


Are you sure your sysctl.conf is correct? Did you remove all the ";" and "'"?

yes, copied your post exactly...

maybe leave it as it is for test?

net.ipv4.tcp_syncookies
kernel.sched_features

both returned an error, unknown key

You are right. This sysctl.conf is not so universal, we can't change these values, but it's not a problem.
The main problem were the ";" and "'" in sysctl.conf.

Since noone was updating it, I provide a working flashable zip basing on this mod. There were more than one problem in the zip, but now I fixed them. Please report:
* if you notice a battery performance improvement
* how much is this improvement
* which MOD are you on
* which KERNEL are you on. This mod works only on init.d featured mod/kernels.
thanks.

Flash this through CWM recovery!

Is his considered universal, meaning foe all firmware versions?

Yes, it's kernel-level tweaks, should work on any MOD/KERNEL (miui & CM included), just make sure init.d is supported. If you want to verify if it's working after installation you can also make a check:
* open terminal emulator
* type: sysctl fs.nr_open
it should read 1053696.

Any one can feedback after using this mod??
