Changing tc passwd via SSH -> can't connect via SSH anymore
« on: February 26, 2014, 07:28:31 AM »
After changing the tc password via SSH or from the local console, i can't connect via ssh anymore. It always asks me to change my expired password :

$ ssh tc@192.168.1.45
tc@192.168.1.45's password:
 (�-

Some details, after changing the passwd, i use backup to keep the current /etc/passwd and /etc/shadow. After reboot i get 2 files for each passwd and passwd-, shadow and shadow-.
the password hash is different in shadow and shadow-.

Check system date. Is it year 1970 or 2014?

It's 70, because i didn't find how to set the time automatically.

getTime.sh does not work on my picore.

Ok i fixed the problem : it came from the date.

 - all the file on the sd are in 2014
 - but when i start the pi, the date is not synchronized, i have to find how to do that (i force the current date with sudo ntpdate 192.168.1.254), and the date is 1/1/1970
 - so when i change the passwd via ssh the modified file is in 1970.
to fix the problem :
 -  run ntpdate to force the current date
 - make  a "touch passwd" to correct the date
 - and now i can connect via ssh

Thanks a lot bmarkus ;-)

Ok the new getTime.sh command does not work for me, but i'm behind a firewall

i can use the /bin/ntpd -q -p 192.168.1.254 (address of my firewall which has ntp too) in the bootlocal.sh to do the trick

Thanks

Thanks for the feedback. You can add it to bootlocal.sh to get time at startup.
