- e12e 11y agoThat doesn't appear to be the same article - so this isn't a duplicate story - just a duplicate (but much more recent) mention of the technology in question.
- fulafel 11y agoAre there advantages for Ubuntu users over enabling the Firefox AppArmor profile? (And why doesn't that default to on, anyway?)
- satai 11y agoYou can do both, there is no need to decide between MAC and firejail. (It may not work for some small quirks but they should be fixable, at least in theory)
- yadascript 11y agoCould Firejail be used as the isolation layer for an online IDE ?
- jeswin 11y agoSorry off topic, but just wanted to check if I can reach you by email. I am building something on those lines, and wanted to see if we can exchange ideas. My email is on my profile.
- mynewtb 11y agoI had no idea it was so easy to use! > The --net=none option will create a new network namespace without any devices, so processes cannot communicate outside of the namespace. No idea what a namespace is, does this mean the process will be unable to use any network? I want that as default for everything on my machine...
- cesnja 11y agoLinux namespaces isolate certain functionality for a group of processes. See more here: http://man7.org/linux/man-pages/man7/namespaces.7.html http://man7.org/linux/man-pages/man7/namespaces.7.html And yes, a blank new network namespace won't even have the loopback interface available. There is a program named unshare, which executes a program in another namespace.
- digi_owl 11y agoReally wish there was a basic set of commands for manipulating namespaces. It seems we are reliant on support being baked into larger tools like systemd at present, and said tools may not allow the user/admin to manipulate namespaces directly.
- krakensden 11y ago"ip" will let you futz around with network namespaces in an ad hoc way. There's a good LWN intro to it somewhere.
- tobbyb 11y agoThe unshare tool [1] can be used along with ip-tools to create a namespace with networking support. Add a chroot or pivot root to it and you have a Linux container. It's quite easy to do. We have a guide on using namespaces directly and the various projects using it including Firejail here [2] Linux namespaces were created to support containers. This is how userland container projects like LXC, Docker and Nspawn work, only they don't use the unshare tool but the underlying system calls clonens, setns and unshare [3].

- digi_owl 11y agonamespaces is one of those things that make my head hurt. I guess they can be likened to a surname or such, except that they don't seem to require explicit naming upon creation.
- agentgt 11y agoPardon my ignorance as I am a long time Linux user now using OSX.. are there any good sandbox tools for OSX?
- SeriousM 11y agoJust for the record: http://www.sandboxie.com/ http://www.sandboxie.com/ is THE sandbox tool for Windows.
