Shared Memory and Semaphore on Omega2
Johannes Kuhnert Roca
currently I'm working with semaphores and shard memory functionalities on the omega. Which seems to work fine, as the results of my two processes are correct.
However I can't find a command on the omega to retrieve the IPC list, as I'm used to get on my host pc. On my host machine (Linux Debian 8 ) I'm able to use the "ipcs" command with the used semaphore and shared memory.
Can anyone help?
I think that the
ipcscommand was not enabled with busybox in the stock Omega2 image. Only way to enable this, is to create a custom image and enable that feature for busybox.
The "full" BusyBox v1.26.2 has an
ipcsfunction/applet too, unfortunately I haven't tried it yet.
(Lastly I replaced Omega's busybox
cp /root/busybox-mipsel /bin/busyboxand made some symlinks.)
