At start of this, there is no /proc/sys/net/ipv6/config/eth30 dir because all IPv6 addrs were removed (I suppose). # ./local/sbin/ip -6 addr add 2345::18 dev eth30 # echo 1 > /proc/sys/net/ipv6/conf/eth30/autoconf # cat /proc/sys/net/ipv6/conf/eth30/autoconf 1 # ./local/sbin/ip -6 addr del 2345::18 dev eth30 # cat /proc/sys/net/ipv6/conf/eth30/autoconf cat: /proc/sys/net/ipv6/conf/eth30/autoconf: No such file or directory What is the proper way to turn on ipv6 auto configuration?
