Gord_W Posted December 12, 2017 Posted December 12, 2017 (edited) Hi, Noobee here. I'm using a NanoPi NEO with the latest legacy image updated. Using ssh to access device. Linux Lap 3.4.113-sun8i #4 SMP PREEMPT Wed Nov 22 13:45:28 CET 2017 armv7l armv7l armv7l GNU/Linux In the journalctrl log I'm getting repeated failures for ntpd and cron about every minute. 1) The router that I'm connected to is IPv4 only. In nmtui I'v set the connection to ignore IPv6, but it seems that IPv6 has not been disabled. A IPv6 IP address has been assigned to the wireless interface. Should I be doing something else? 2) Cron is constantly doing something with armbian-updates. Is this normal?? diagnosis information will now be uploaded to http://sprunge.us/VfcK Regards, Gord_W Dec 12 08:04:22 Lap ntpd[902]: bind(22) AF_INET6 fe80::42a5:efff:fed2:ee52%4#123 flags 0x11 failed: Cannot assign req Dec 12 08:04:22 Lap ntpd[902]: unable to create socket on wlx40a5efd2ee52 (400) for fe80::42a5:efff:fed2:ee52%4#123 Dec 12 08:04:22 Lap ntpd[902]: failed to init interface for address fe80::42a5:efff:fed2:ee52%4 Dec 12 08:05:01 Lap cron[455]: (*system*armbian-updates) INSECURE MODE (group/other writable) (/etc/cron.d/armbian-up Dec 12 08:05:01 Lap CRON[9046]: pam_unix(cron:session): session opened for user root by (uid=0) Dec 12 08:05:01 Lap CRON[9047]: (root) CMD (command -v debian-sa1 > /dev/null && debian-sa1 1 1) Dec 12 08:05:01 Lap CRON[9046]: pam_unix(cron:session): session closed for user root Dec 12 08:06:01 Lap cron[455]: (*system*armbian-updates) INSECURE MODE (group/other writable) (/etc/cron.d/armbian-up Dec 12 08:06:22 Lap ntpd[902]: bind(22) AF_INET6 fe80::42a5:efff:fed2:ee52%4#123 flags 0x11 failed: Cannot assign req Dec 12 08:06:22 Lap ntpd[902]: unable to create socket on wlx40a5efd2ee52 (401) for fe80::42a5:efff:fed2:ee52%4#123 Dec 12 08:06:22 Lap ntpd[902]: failed to init interface for address fe80::42a5:efff:fed2:ee52%4 Dec 12 08:07:01 Lap cron[455]: (*system*armbian-updates) INSECURE MODE (group/other writable) (/etc/cron.d/armbian-up Dec 12 08:08:01 Lap cron[455]: (*system*armbian-updates) INSECURE MODE (group/other writable) (/etc/cron.d/armbian-up Dec 12 08:08:22 Lap ntpd[902]: bind(22) AF_INET6 fe80::42a5:efff:fed2:ee52%4#123 flags 0x11 failed: Cannot assign req Dec 12 08:08:22 Lap ntpd[902]: unable to create socket on wlx40a5efd2ee52 (402) for fe80::42a5:efff:fed2:ee52%4#123 Dec 12 08:08:22 Lap ntpd[902]: failed to init interface for address fe80::42a5:efff:fed2:ee52%4 Dec 12 08:09:01 Lap cron[455]: (*system*armbian-updates) INSECURE MODE (group/other writable) (/etc/cron.d/armbian-up Dec 12 08:10:01 Lap cron[455]: (*system*armbian-updates) INSECURE MODE (group/other writable) (/etc/cron.d/armbian-up Dec 12 08:10:22 Lap ntpd[902]: bind(22) AF_INET6 fe80::42a5:efff:fed2:ee52%4#123 flags 0x11 failed: Cannot assign req Dec 12 08:10:22 Lap ntpd[902]: unable to create socket on wlx40a5efd2ee52 (403) for fe80::42a5:efff:fed2:ee52%4#123 Dec 12 08:10:22 Lap ntpd[902]: failed to init interface for address fe80::42a5:efff:fed2:ee52%4 Dec 12 08:11:01 Lap cron[455]: (*system*armbian-updates) INSECURE MODE (group/other writable) (/etc/cron.d/armbian-up Dec 12 08:12:01 Lap cron[455]: (*system*armbian-updates) INSECURE MODE (group/other writable) (/etc/cron.d/armbian-up Dec 12 08:12:22 Lap ntpd[902]: bind(22) AF_INET6 fe80::42a5:efff:fed2:ee52%4#123 flags 0x11 failed: Cannot assign req Dec 12 08:12:22 Lap ntpd[902]: unable to create socket on wlx40a5efd2ee52 (404) for fe80::42a5:efff:fed2:ee52%4#123 Dec 12 08:12:22 Lap ntpd[902]: failed to init interface for address fe80::42a5:efff:fed2:ee52%4 Dec 12 08:13:01 Lap cron[455]: (*system*armbian-updates) INSECURE MODE (group/other writable) (/etc/cron.d/armbian-up Dec 12 08:14:01 Lap cron[455]: (*system*armbian-updates) INSECURE MODE (group/other writable) (/etc/cron.d/armbian-up Dec 12 08:14:22 Lap ntpd[902]: bind(22) AF_INET6 fe80::42a5:efff:fed2:ee52%4#123 flags 0x11 failed: Cannot assign req Dec 12 08:14:22 Lap ntpd[902]: unable to create socket on wlx40a5efd2ee52 (405) for fe80::42a5:efff:fed2:ee52%4#123 Dec 12 08:14:22 Lap ntpd[902]: failed to init interface for address fe80::42a5:efff:fed2:ee52%4 Dec 12 08:15:01 Lap cron[455]: (*system*armbian-updates) INSECURE MODE (group/other writable) (/etc/cron.d/armbian-up Dec 12 08:15:01 Lap CRON[9100]: pam_unix(cron:session): session opened for user root by (uid=0) Dec 12 08:15:01 Lap CRON[9101]: (root) CMD (command -v debian-sa1 > /dev/null && debian-sa1 1 1) Dec 12 08:15:01 Lap CRON[9100]: pam_unix(cron:session): session closed for user root Dec 12 08:16:01 Lap cron[455]: (*system*armbian-updates) INSECURE MODE (group/other writable) (/etc/cron.d/armbian-up Dec 12 08:16:22 Lap ntpd[902]: bind(22) AF_INET6 fe80::42a5:efff:fed2:ee52%4#123 flags 0x11 failed: Cannot assign req Dec 12 08:16:22 Lap ntpd[902]: unable to create socket on wlx40a5efd2ee52 (406) for fe80::42a5:efff:fed2:ee52%4#123 D Edited December 12, 2017 by Gord_W Change to Solved

To fix on your own, check https://forum.armbian.com/search/?&q=insecure mode
Gord_W Posted December 12, 2017 Author Posted December 12, 2017 Thanks Igor. For Reference: chmod 644 /etc/cron.d/armbian-updates has stopped the INSECURE MODE problem. For item 1) above to stop IPv6 see http://www.binarytides.com/disable-ipv6-ubuntu/ I used this method: Method 1 - Disable from sysctl The first method to disable Ipv6 is to edit kernel level parameters via sysctl interface. The kernel parameters that enable ipv6 are as follows $ sysctl net.ipv6.conf.all.disable_ipv6 net.ipv6.conf.all.disable_ipv6 = 0 $ sysctl net.ipv6.conf.default.disable_ipv6 net.ipv6.conf.default.disable_ipv6 = 0 $ sysctl net.ipv6.conf.lo.disable_ipv6 net.ipv6.conf.lo.disable_ipv6 = 0 Note that the variables control "disabling" of ipv6. So setting them to 1 would disable ipv6 Edit the file - /etc/sysctl.conf $ sudo nano /etc/sysctl.conf And fill in the following lines at the end of that file # IPv6 disabled net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 net.ipv6.conf.lo.disable_ipv6 = 1 Save the file and close it. Restart sysctl with $ sudo sysctl -p Check the output of ifconfig again and there should be no ipv6 address Thanks, Gord_W 2
Gord_W Posted December 12, 2017 Author Posted December 12, 2017 Could disabling IPv6 be added to the armbian-config in the Network Section? Would make it easier for people like me. Gord_W
Igor Posted December 12, 2017 Posted December 12, 2017 This whole Armbian thing is a common work and we already work at maximum capacity. Try to add this feature on your own - you only need to check this section: https://github.com/armbian/config/blob/dev/debian-config-jobs#L728-L736 and this line: https://github.com/armbian/config/blob/dev/debian-config-submenu#L524 as a similar example how to add a feature to the config. The rest you do with bash utilities. Use this method: https://docs.armbian.com/Process_Contribute/ 2
Gord_W Posted December 12, 2017 Author Posted December 12, 2017 Hmm, I had a look at the pages you suggested. Would like to help but that is way above my pay grade. Sorry. Gord_W
pfeerick Posted December 13, 2017 Posted December 13, 2017 I'll bite... it'll give me a chance to have a ferret around in armbian-config It shouldn't be hard thanks to the config stuff Gord_W' found. 1
