Before I jump in
-Is it going to be hell to use both an nVidia card and AMD card at same time? Or are the drivers/X11 smart enough to keep them separate but working together? Had to find very specific AMD drivers just for Windows to work right
-Did they fix sound mixing (applications taking sole control of sound device, there were layers and software solutions/wrappers to try to fix this but lots of compatibility issues between them all)

The problem I have with polished desktops is that I inevitably run into something that doesn't work right. Then I am digging and before you know it I find some code fix by some guy in the back corner of the google groups and need to make/compile it myself, but then I need certain libraries at certain versions that the package manager doesn't want to use because they're incompatible with some other poo poo. I end up tweaking for a couple hours, get everything working right, but then at that point I might as well be using an OS designed to let me tweak and customize it to begin with. I don't mind it at all.

Boris Galerkin: Dec 17, 2011; I don't understand why I can't harass people online. Seriously, somebody please explain why I shouldn't be allowed to stalk others on social media!

I want to set up ssl on my website with the caveat that I want a different ssl certificate for a specific subdomain. So, I'd like example.com and www.example.com to use the same certificate, while test.example.com uses one specific to that subdomain. I'm going to be requesting these from Let's Encrypt and I was a bit confused about the part where I generate an account.key. As I understand it, this account key represents something like a user account at Let's Encrypt, so it makes sense to me that I only want one account.key that's shared between these two certificates. I'll generate two domain keys: example.com.key and test.example.com.key. Is this correct or should I be using two different account keys?

At the moment I've used just a single account key, and ssllabs is giving me weird results:

For example.com:

For test.example.com:

Both server configurations are completely identical so I'm not sure why one score is higher than the other.

Furthermore, the test results for test.example.com (the one that scored higher) also shows this:

It's complaining about mismatch because "certificate #2" is actually the certificate for the main site, which shouldn't even be offered to test.example.com. How do I disable this behavior? When I type "nginx -V" it tells me that SNI is supported.

If I manually visit test.example.com and click on the little lock icon it does tell me that the certificate is for test.example.com and that it's valid though.

Here's the relevant conf for the domains:

code:

server {
    listen      443 ssl http2 default_server;
    server_name example.com [url]www.example.com;[/url]

    ssl_certificate     /config/example.com-letsencrypt.pem;
    ssl_certificate_key /config/example.com.key;

    ...
}

server {
    listen      443 ssl http2;
    server_name test.example.com;

    ssl_certificate     /config/test.example.com-letsencrypt.pem;
    ssl_certificate_key /config/test.example.com.key;

    ...
}

I've got another question this time about the file sshd_config.

In my Fedora box the default is figured with the following line:

code:

Subsystem sftp /usr/libexec/openssh/sftp-server

In Debian:

code:

Subsystem sftp /usr/lib/openssh/sftp-server

I'd like to have a single sshd_config file that all my machines can use without modification. Is this line really needed and/or how can I ensure compatibility? Just symlink one path to the other and hope I remember to make these symlinks when I deploy a new machine? Include both lines (with one pointing to a nonexisting directory)? Is there some kind of if/else clause I can use in these files?

e: Now that I think about it, I have never in my life used the command "sftp ..." anything in my life that I can remember. If I ever needed to copy files over I always just use scp. Do I even need this line in my configuration?

you're probably stuck using sed/awk/perl. check for /etc/fedora-release or the debian equivalent, search and set the options and add the missing stuff at the end. it looks like there's a dormant pr for adding an include directive like ssh_config already has, but it's not implemented yet.

Why does tailing the last n lines of a file and then tee'ing them back to the same file sometimes work and sometimes result in a null file?

quote:

tail -n20 /home/me/logfile.log | tee /home/me/logfile.log

Sometimes ends up with the last 20 lines in logfile.log and sometimes 0 lines.

What's the preferred solution for a shared drive between Linux and Windows? Do not want to use FAT32 because of the 4GB limit.
Which leaves NTFS, exFAT, or possibly ext4 driver for Windows (Maybe this? http://www.ext2fsd.com )

Kassad: Nov 12, 2005; It's about time.

I'm pretty sure that going with NTFS is easier. Just make sure Windows shuts down fully (no hibernation or that fast boot thing in Windows 10) or the drive will be locked in Linux.

Well I guess I can't use Linux after all. Everything smooth setting up Arch Linux until i got to setting up Xorg. Glamor is not compatible with my GPU (7870 Tahiti Edition, a really bizarre card that is basically what a Radeon 7930 would have been). Did a lot of digging and it's just a known bug for 6 years that will probably never be fixed. Weston doesn't work either.

I might try flashing a modified Radeon 7950 Bios on it just to see what happens, though I can imagine the 2GB vs 3GB issue could be a problem. I'm pretty comfortable with modding AMD Atom bios so maybe I'll have some luck.

Also turns out my mobo has incomplete Efi hand off for UEFI video cards so I had to rip out the Uefi out of the GPU bios just to get it to boot with efi preferred enabled in mobo bios. loving Asus.

Oh and my windows partition won't boot anymore after converting from mbr to gpt, turns out there's more work than that involved for EFI Win10

And also all the cmos clears I've had to do over past couple days corrupted the Intel management engine in my Bios, unfixable with simple bios reflash. Basically meant disabled overclocking, disabled igpu, and even disabled all but 8 gigs of ram. Intel ME is what says "oh you have a 2500K sku, let me unlock your multiplier and enable the GPU and other basic features like Turbo". Not something you want in a dysfunctional state. I had to patch together a new bios with same config with Intel firmware maker tool but replaced Intel ME image from known good image binary, then use Intel FPT to full erase and full rewrite the recreated flash image to the chip. Fixed it though and all the advice I saw before was saying I'd have to buy a new bios chip for my mobo off ebay. :colbert:

This is what linux does to me. That and because I want to use UEFI for everything instead of legacy because it will shave like 3 loving seconds off the boot time, even though my mobo has halfassed UEFI implementation that wants to fight me all the way.

I've got a simple question. Or at least it should be.
I know many, many years ago I used to have a setup where I had an HTTP server running on the PC which I also saved my files. The HTTP server could display the files in directories. I'm pretty sure it was a little less harsh than a plain old Apache directory listing.

Really all I want to do is have access to my eBooks and some other things on my network via web based directory listings, but a little customizable. I've got a dedicated SBC server running Armbian that I use these days.

The main reason for wanting the listings is so the rest of my family can have easy access to things especially on mobile devices at home rather than screwing with NFS and SMB.

In theory, UEFI is like the second coming and is perfectly deserving of the praise. In practice, if a MB manufacturer hosed up the old BIOS, it can and will gently caress up the UEFI. Yes, there's one unified interface and 100 billion implementations in which the same function call will do 100 billion different things, one of which is what you want. But at least we got a pretty mouse-driven motherboard UI.

It's definitely cool and makes it feel like the BIOS is hooking directly into doing something useful instead of being a giant Rube Goldberg machine that decades of clever engineers and duct tape engineers working around various hardware limitations has gotten us to.

In practice though, my computer was working just fine in legacy/mbr.

I found an article on setting up a Pi 3 with it, so I guess there's source, or an ARM binary. I'm using an Orange Pi Zero.Looks like there's a package in the repo.

So I did a �dnf upgrade� on my ThinkPad running Fedora and after rebooting i couldn�t login anymore. The login screen shows up, but logging in immediately crashes and exits me back to the login screen. I thought maybe I had something wrong in my dotfiles because I just updated them so I just removed them but no dice.

Turns out a gnome plugin broke in this upgrade (it was working fine before) and it causes some usb devices, namely iPhones, to cause gnome to crash.

Trip report on the Calibre server. Holy poo poo what a pain in the arse. I had to copy something like 20GB of books to the PC so I could send them though a copy of Calibre to get them into the library before copying the librarified directory tree back across to the server.
Long story short, the SBC based server just couldn't do it. For some reason adding books would explode seemingly when it tried to invoke pdfinfo. Couldn't quite pinpoint the failure mode.

In the end it took over a day of shuffling files etc. but calibre-server seems to work quite well! I was worried it would be slow given how clunky the UI is.

Sometimes, I think I'm pretty dumb. I just set up SaltStack on my home infrastructure (about 20 Linux VMs) and played around with centralized updates and maintenance because management was getting very tedious. This is ... so much easier. Are you kidding me? Why am I so dumb? Why did I wait so long to try this?

We've got two sftp servers that our customers use. Each customer has their own folder under /sftphome, which is a gluster volume. The customers' sftp access is restricted to their folders, and each folder has uid/gid unique to that customer. What's the best way to migrate this data across the country to a similar pair of sftp servers? There are currently around 200 users, and potentially many more, and we could potentially make a service account in each group (the servers are CentOS 6, so we won't hit NGROUPS_MAX), but I don't know if like rsync or ssh or gluster's geo-replication or anything else could run into issues if they see a user with a few hundred groups.

a copy operation isn't going to look at the users, just the permissions on the files. I'd use rsync.
