Hello, I don't find a working way to completly disable the use of IPv6 on armbian.
I'm using Armbian_5.69_Orangepipc2_Debian_stretch_next_4.19.13.img, fresh install with etcher/balena.
I've added the file /etc/sysctl.d/10-NoIPv6.conf with this content:
net.ipv6.conf.lo.disable_ipv6=1
net.ipv6.conf.default.disable_ipv6=1
net.ipv6.conf.all.disable_ipv6=1
I've modified /etc/hosts like that:
127.0.0.1 localhost orangepipc2
I've rebooted.
But i still have ipv6 enabled and working, as the output of the "ip a" command give:
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
link/ether 02:01:0f:67:00:7f brd ff:ff:ff:ff:ff:ff
inet 192.168.0.99/24 brd 192.168.0.255 scope global dynamic eth0
valid_lft 42659sec preferred_lft 42659sec
inet6 fe80::1daa:72ca:7f4c:4ce/64 scope link
valid_lft forever preferred_lft forever
3: enx180f76faae7b: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000
link/ether 18:0f:76:fa:ae:7b brd ff:ff:ff:ff:ff:ff
The enx180f76faae7b iface is a dlink usb gigabit ethernet, i've tried also with and without it attached, still ipv6, and if i don't plug eth0 and plug the networkwire on this USB eth card, same, still have ipv6.
How is it possible to disable ipv6 on a debian armbian based system?
Can someone help me?
I've already search the forum, and found many "working for me with adding the line in sysctl", but with no explanations, i've tried with and without trimming the space into the systctl file, same.
I'm starting to eat my fingers and arguing with my board, please, help us to become friends again, my board and me
