network namespaces

Are network namespaces supported in snaps? In my RaspberryPi3 I have a snap which has been installed with --devmode. Inside the snap I have exposed the command 'bash'. I exec that bash as root. Then I try to create a network namespace. It fails. $ sudo myapp.bash # ip netns add ns0

tcpdump armhf

For debugging my app, I need to run "tcpdump" on my Ubuntu Core based Raspberry Pi. This tool is not installed in the "core" snap. A run of "snap find tcpdump" returns 0 results. What's my best move? Make a snap on my own and use launchpad snap-builders to produce the one for armhf? --Luca --

The results are the very same (apart for "namespace") on a real machine, so the LXD container shouldn't be the cause. On Sat, Feb 4, 2017 at 12:14 PM, Luca Dionisi <luca.dion...@gmail.com> wrote: > More in context: > > In a classic Ubuntu (but inside a LXD container) I ru

Re: Where to save stuff (in snap-agnostic way)

Thanks all for the answer. There's a catch, though. I just checked in a classic Ubuntu what the XDG_RUNTIME_DIR env is set to for root. And, surprise, it's not set. So, since my app has to run as root, it seems that I'll have to check this possibility too. --Luca On Sat, Feb 4, 2017 at 3:47 AM,

Where to save stuff (in snap-agnostic way)

What is the best place to write (and read) a temporary FIFO file from a confined snap application? This is for simple IPC between 2 processes of the same snap. Before attempting to snap the application I was using a fixed filename in /tmp. Admittedly poor solution. The solution should be usable

Re: Unable to ssh to RPi3 after initial configuration of Ubuntu Core

Just a couple of hints. 1. Double check username. It might be different than that of the email you use to signon at Ubuntu. E.g. my mail is luca.dion...@gmail.com while user on my RPi is luca-dionisi. 2. Try flag "-v" with ssh. Check the id_rsa* files that it tries with. On Fri, F

Re: Vala and Snapcraft. Issues with a library part in Vala.

This is another solution that I thought of. I want to put the library mylib-y (the one that is needed by mylib-x) both in the ./stage tree and in the /usr/ prefix of the host system where I prepare the snap. Is there a way to tell snapcraft to do so? It should be similar to the way one can use

Hi all I see that the issue has been taken care of. I will immediately download a daily-build image and check that the file rt_tables is writeable. I haven't built a snap for my app yet, so I cannot test for the moment if my needs are all already fitted in the builtin interfaces. I will try as
