Activate ip forwarding - persistent - ubuntu core

favorite












I'm trying to activate ip forwarding at boot-time on my ubuntu core image. I can run the command:



sudo sysctl -w net.ipv4.ip_forward=1


It works. Then I reboot the machine, the forwarding is gone.
On ubuntu server I can update the file /etc/sysctl.conf .



This file is "read only" in ubuntu-core.



What is the "prefered" way to add ip forwarding in ubuntu core?

          If you have superuser permissions you can edit any file with any permissions. Open /etc/sysctl.conf with your favourite editor (vi, nano etc) find string #net.ipv4.ip_forward=1, remove the leading # symbol, save the changes. And run sudo sysctl -p.



          Also, you can reboot your machine to make sure the changes are in place.

                    Quarter-circle Tiles

                    Image
                    up vote 0 down vote favorite I have $99$ identical square tiles, each with a quarter-circle drawn on it like this: [asy] size(1.5cm); draw(Arc((2,0),1,90,180),red+1); draw((0,0)--(2,0)--(2,2)--(0,2)--(0,0)); [/asy] When I arrange the tiles in a $9times 11$ rectangular grid, each with a random orientation, what is the expected value of the number of full circles I form? I think this problem has to do with finding the chance any given 2x2 square has a circle, but I can't find it. expected-value share | cite | improve this question asked Nov 20 at 15:03 6minecraftninja 1 2

                    build a pushdown automaton that recognizes the reverse language of a given pushdown automaton?

                    Image
                    0 I think it's similiar to NFAs. I replace the finite states of the given automaton for start-states for my new automaton. I do it with $epsilon$ -transition from the start state to the actual finite states of the given automaton. The start state of the given automaton will be my accepting(finite) state of my new one. All transitions will be reversed of course to recognize the reversed word. But how do I have to change the stack of the pushdown automaton? That's tricky. formal-languages automata context-free-grammar share | cite | improve this question edited Nov 29 '18 at 14:20 joee
