Dear all,

I am new to this group.

I am running two RFC2460 test items, v6LC.1.3.2 (Part B&C) to check the device (Tablet) behavior when sending a ping and the network part gets the packet fragments.

I am trying to run it through an ADB command, but when entering with the following commands:

1. First help to get the following information:
cat /proc/sys/net/ipv6/ip6frag_time  
See if it's 60.
2. Do an experiment, see under the settings, is it possible to pass
sysctl -w net.ipv6.ip6frag_time=58
or
echo 58 > /proc/sys/net/ipv6/ip6frag_time


But upon entering with  adb devices>adb root>adb shell then the script above, the system returns with a message 'sysctl: key 'net.ipv6.ip6frag_time': Permission denied'

See sequence at the enclosed screenshot.

Do you have any idea of whats is missing in the script or is that may be any other issue?

Thanks for your attention.
