So, I'm building hadoop cluster with raspberry right now, I need to disable ipv6 connectivity, and need to know whether ipv6 has been disabled or not.
In some guide
cat /proc/sys/net/ipv6/conf/all/disable_ipv6 is supposed to give the result I want, but for some reason if I enter it my terminal said
"no such files or directory".
Do you have some suggestions?
nb : there is already a question about ipv6 in 'IPv6 connectivity', but i didn't find the answer, and what i ask is how to disable and check whether it's disabled or not, while the other question is about enabling it, thanks.
