Alex_UUU

Who kills the user process?
Greetings.
Orange Pi Zero

1. <p>Root @ orangepiplus: / var / log # uname -r</p><p>3.4.39</p>

Copy code

All programs are executed under the root. All is well.
But if you borrow under the user. Then we get:

1. <p>Alex_UUU @ orangepiplus: ~ $ sudo</p><p>Killed</p><p>Alex_UUU @ orangepiplus: ~ $ ps ax</p><p>Killed</p><p>Alex_UUU @ orangepiplus: ls /</p><p>Bin dev home lost + found mnt proc run srv tmp var</p><p>Boot etc lib media opt root sbin sys usr</p><p>Alex_UUU @ orangepiplus: ~ $</p>

Copy code

There is nothing in the logs.

1. <p>Root @ orangepiplus: / var / log # getent passwd Alex_UUU</p><p>Alex_UUU: x: 1001: 1001 :: / home / Alex_UUU: / bin / bash</p>

Copy code

In /etc/sudoers

1. Alex_UUU ALL = (ALL: ALL) ALL

Copy code

What is wrong? What nuances can be?
