I use Ubuntu 15.10 (64bit). I tried to run ulimit -n 102400, but after reboot or relogging (log out and log in) and excuting ulimit -n I see: 1024. I tried adding
* soft nofile 102400
* hard nofile 102400
to /etc/security/limits.conf but as I said before, I still get 1024. How can I change the max limit of opened files?
