Set the date in Begalebone Black using ntp Debian 8.9 -


i've been trying set correct date in beaglebone black solutions i've tried not permanent, everytime poweroff beagle , power on later, date wrong again. looks like:

root@beaglebone:~# date sat may 21 17:48:28 cdt 2016

then installed ntp , ntpdate

root@beaglebone:~# apt-get install ntp ntpdate reading package lists... done building dependency tree reading state information... done ntp newest version. ntpdate newest version. 0 upgraded, 0 newly installed, 0 remove , 1 not upgraded.

after edit ntp.conf file this

# pool.ntp.org maps 1000 low-stratum ntp servers.  server # pick different set every time starts up.  please consider joining # pool: <http://www.pool.ntp.org/join.html> server 0.north-america.pool.ntp.org server 1.north-america.pool.ntp.org server 2.north-america.pool.ntp.org server 3.north-america.pool.ntp.org ... # clients (example!) subnet have unlimited access, if # cryptographically authenticated. #restrict 192.168.123.0 mask 255.255.255.0 notrust restrict 192.168.0.11 mask 255.255.255.0 nomodify notrap

the next step was

root@beaglebone:~# rm /etc/localtime root@beaglebone:~# ln -s /usr/share/zoneinfo/america/mexico_city /etc/localtime

after supposed enable ntp service with

root@beaglebone:~# systemctl enable ntpdate.service failed enable unit: no such file or directory  or  root@beaglebone:~# service ntpdate start failed start ntpdate.service: unit ntpdate.service not found.

i couldn't continue thas because don't have ntp.service file tried this

root@beaglebone:~# timedatectl set-ntp true root@beaglebone:~# timedatectl status       local time: sat 2016-05-21 18:16:10 cdt   universal time: sat 2016-05-21 23:16:10 utc         rtc time: sat 2016-05-21 23:16:11        time zone: america/mexico_city (cdt, -0500)  network time on: yes ntp synchronized: yes  rtc in local tz: no  root@beaglebone:~# nano /etc/systemd/timesyncd.conf [time] ntp=0.north-america.pool.ntp.org 1.north-america.pool.ntp.org 2.north-america.pool.ntp.org 3.north-america.pool.ntp.org fallbackntp=0.debian.pool.ntp.org 1.debian.pool.ntp.org 2.debian.pool.ntp.org 3.debian.pool.ntp.org

finally reboot , seems work

root@beaglebone:~# timedatectl status       local time: sun 2017-09-10 23:32:28 cdt   universal time: mon 2017-09-11 04:32:28 utc         rtc time: mon 2017-09-11 04:32:28        time zone: america/mexico_city (cdt, -0500)  network time on: yes ntp synchronized: yes  rtc in local tz: no

but again, after poweroff time sets may 21st, 2016. tried set , sync clock manually hwclock --set --date "date" --localtime , systohc after poweroff result same.

am missing or doing wrong?

i change 'utc' 'local' in /etc/adjtime , time goes may 2016.

thanks.

try this:

dpkg-reconfigure tzdata

this should work. prompt appears , can configure graphical interface. easy america , enter. , then, can pick time zone, too.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
