RFC2324 posted:This is home lab, I'm starting simple so I know how it goes from the ground up. Explicit version requirements in a manifest for applications are one thing. Don't pin nodes, though. It's better for a complete QE cycle to use something like pulp if you can, and to push updates via ansible or katello or whatever instead of yum-cron, which may update critical packages at any given time.

Am I OK copying 64 bit Firefox into /usr/bin? I've got it in a subdirectory of ~/Documents but would like to sudo it somewhere more tidy. Will it poo poo out on me at some point? Is it general practice to extract custom packages to an elevated permissions directory, since most packages attempt to save their data somewhere in /home?

Sorry. That's what I meant, to put it in /usr/bin/firefox64 (or whatever I call it). My post wasn't accurate. I guess the gist of what I'm asking is "if I extract a package into a directory which requires root privileges for writing, do most packages happily run in there without screwing up?". Edit: Just looked at my /usr/bin and there are no subdirectories in there: I guess it's bad practice to start creating directories in /usr/bin. I'll use /opt since I put bash scripts in there too. Edit2: Just realized your point about it being nonsensical, mixing binaries with other filetypes in a 'bin' directory.

Yep. So I assume that any application which is well concieved wouldn't even try to store files in its own installation directory and instead store any generated content somewhere like ~/.config or ~/.cache. I'm learning, I think.

The old school standard is simply ~/.appname (for Firefox, ~/.mozilla if I recall correctly). Bear in mind Linux is a multi-user OS; you wouldn't want one user to be able to change another's settings, after all, so somewhere in the user's home directory is really the only sensible place to put them.

Does Fedora have some kind of dist-upgrade process for upgrading to the next version? (Or maybe it's possible, but not advisable)

https://fedoraproject.org/wiki/DNF_system_upgrade I think if you are on 20 or earlier you are out of luck unless the old system (https://fedoraproject.org/wiki/FedUp) still works to get you onto 21, though someone else might know more about that.

Preupgrade, or yum/dnf distro-sync. Preupgrade is only necessary for big changes (/bin -> /usr/bin, for example) Fedora support goes for two releases, so you may be SOL if you're still on 20 or older unless you can find a live mirror

Oh ok, no problem then. I wasn't sure if I should wait a bit and go with 24, or use 23 now & upgrade. But if there's an implementation that works, guess I can go with 23.

I've had no problems with 23 and if you're using Gnome desktop you'll be using a newer version, although the differences are minor, so I'd upgrade now and then upgrade again when 24 comes out. I remember reading that Fedora 24 will be the first major distro to have Wayland switched on as default, so another reason to upgrade to 23 now: you can determine that 23 is stable before the big changeover in 24.

Heh, I admire your sarcasm. If Wayland happens in 24 it'll be good to see someone taking the helm. I've played with Wayland for about 5 minutes in F23, so having it enabled as default might allow lazy feckers like me to actually use it for realz and identify bugs and glitches. I'd be surprised if there weren't problems but through daily use these should get ironed out much more effectively.

Anyone have experience pairing a Logitech Bluetooth mouse with Linux (specifically CentOS)? I just bought a MX Master and I can't get to pair via Bluetooth. I can turn it on, press the "connect" button to turn it into pairing mode, and then in the gnome utility in CentOS the mouse shows up and I can click on it to begin pairing but it eventually times out or something and goes back to saying "not set up." gnome-bluetooth (1:3.14.1-1.el7) gnome-bluetooth-libs (same) bluez (5.23-4.el7) Those are the Bluetooth related things I have installed and their version number. I don't know which log files to check to see why it won't pair.

Probably easiest to go one hop upstream to whatever they plug into and figure out their IP addresses. Alternatively nmap the local subnet if that's not an option. If it's a straight image it may or may not have one of either telnet or SSH open - you can confirm by connecting to ports 23 and 22 respectively . Whether SSH allows password logins or not depends on whether anyone locked things down.

Seems like some in here will find this interesting. Microsoft is adding bash shell via help from Canonical in Windows 10. somebodyontheverge posted:"This is not a VM. This is not cross-compiled tools. This is native," he said. "We've partnered with Canonical to offer this great experience, which you'll be able to download right from the Windows Store." https://channel9.msdn.com/Events/Build/2016/P488?ocid=player The video gets to the meat of it around 4:00.

Aren't they also bringing in native ssh as well? I think I heard that not long ago servers will be able to be ssh'ed into and bam into a powershell session.

From an MS employee on another forum: "It's a Linux subsystem that maps calls from Linux to Windows. You run native ELF Linux binaries and subsystem does all the work." So it depends how thoroughly and faithfully they implement all of the syscalls, but at least in theory, it should work eventually. The announcement of Docker on Windows is another interesting development in that area. Varkk posted:Aren't they also bringing in native ssh as well? Yeah.

Varkk posted:Aren't they also bringing in native ssh as well? The current version constantly waits for returns and messes up displaying standard output. There's a module called Posh-SSH that's a little better but it's mostly for batch jobs than to be used as a shell from what I can tell. RDG is still by far the best way to get into a Windows system imo. Psremoting/wsman still has some serious authentication problems

Does anyone have a good guide to the various Linux bonding options for Deb/Ubuntu systems? I've read the kernel bonding documentation here but it's not telling me what I need to know regarding my network, specifically the supported upstream switch configurations. The balance-rr options is completely useless and mainly for when you have two servers connected directly together and need to aggregate bandwidth, but I want an option that lets me do both receive load balancing and xmit load balancing simultaneously. That leaves me with using either 802.3ad mode (LACP) or the balance-alb options, however if I use 802.3ad mode I have to limit myself to connecting to a single upstream switch since we have no VPC/MLAG configured on our datacenter network. I can't find diddly on what the switch topology requirements are if you have a server uplinked to separate physical switches with the balance-alb option. Any tips?

Malloc Voidstar posted:Interix couldn't run Linux programs, AFAIK. With this new thing you can grab a program compiled for Ubuntu and it'll run on Windows. I'd guess a whole new system since MS didn't really like Interix. Well, it could run Linux programs, just not ELF binaries. Whether this grabs a program "compiled for Ubuntu" (hopefully not) or an ELF binary with some kind of depsolver for the library requirements (deb is ok here) is unknown, but I'm struggling to see the use case other than "no, don't get rid of your Windows servers, we can run Linux stuff, too!" in an age where there's absolutely no need for that, because you can trivially virtualize anything, and Powershell exists for Linux if you really want PS management, but I dunno.

Very true about docker, if this subsystem includes enough of the kernel abi to use namespacing and cgroups. I'm not sure about web developers, personally, but maybe. The mindshare will be hard to regain. I'm wondering if this won't get more uptake from Windows infrastructure teams who are curious about Linux or want just this service or that service but want to stay on Windows, until they're managing two ecosystems on one operating system.
