I want to create a personal AWS account to learn with. I know a lot about general cloud concepts but know almost nothing about AWS itself. What's the cheapest way to go about this? I assume I start with 2 of the smallest servers, but what else do I need to know so I don't end up with a $200 credit card bill at the end of the month?

They have a free tier that lasts a year as a trial IIRC. You can run a micro instance 24/7 without any cost in the free tier. I'd start with that and go from there. I don't really think you need multiple servers, but it can't hurt to bring a few up and down (you pay at least for 1 hour of usage though IIRC, but with the micro instances its dirt cheap).

In the process of installing CentOS 7 on a new(old) server and I discovered that RHEL no longer packages the forcedeth driver(for nVidia network cards) in the default kernel, and therefore neither does CentOS. Apparently not the e1000 driver either, and a few more older, but very common, net drivers What the gently caress? Every single server I work on uses one of these 2 drivers.

Yeah, I found it, but even my gigabit network card on a 3 year old motherboard uses forcedeth, so its not like its only on decade old hardware(I found out setting up a refurb sun x4140 I picked up real cheap as a quick and dirty home lab virtualization host). I was just shocked to see that it wasn't even included, I would assume the module would be there but not loaded in any way. Its only 47k.

On this note, is there a port of the Solaris diagnostic tools for linux? specifically prtdiag and cestat/cediag. Those are ever so much more useful for keeping tabs on sun hardware than anything I have ever found for linux.

First 12 months http://aws.amazon.com/free/ I used the free tier for an entire year at no cost when I first wanted to get a feel for things. Its plenty to set up and tinker, if you just have a single instance of each thing it doesn't cost anything. If you are just experimenting and not running an actual website you can shut the instances down when you aren't using them and that might allow you to run multiple things during testing.

I've started learning C++. I store all my .cpp files in a folder on an external hard drive. I compile them using g++, but when I try to execute the output (./a.out) I get a "permission denied" message. The only way I can get my program to run is if I copy the .cpp file to my internal hard drive and compile there. Then it works. Why is it like this?

Your system may be configured to mount external discs with the "noexec" flag, which is a modicum of protection against people executing random poo poo they got off their friend's USB stick. Run "mount" to see what flags are applied to that drive.

If I compile a .cpp file that's on my external drive, then copy the file to my Home folder on my internal drive, I still get the "permission denied" message. It is only when I compile the file when it is on my internal drive that it works properly. edit: I have to type chmod 755 a.out

So I'm having a syslinux issue trying to make a bootable rescue USB. Here's the situation: Partition 1: primary, ext2, bootable, contains extlinux and extlinux configuration and boot images for HDT, memtest, etc Partition 2: primary, iso9660, dd'd from an openSUSE rescue image. The MBR is the standard syslinux mbr.bin. The syslinux.cfg contains: code:However, when I try actually booting it, I get an "isolinux.bin missing or corrupt" error. I know that the embedded iso is an isohybrid image created with --partok, because if I mark partition 2 bootable instead, it boots right into the rescue system with no trouble whatsoever. What am I doing wrong here? How do I correctly chainload an isohybrid image embedded in a partition? Alternately, is there any way I can patch the partition table in memory to change which partition is marked bootable and then re-run the MBR? I vaguely remember grub having a "makeactive" command that did something like that. I know I could just copy the contents of the iso image and then use syslinux/extlinux to make the ensuing partition bootable, but ideally I'd like to have it working with the isohybrid image, so I can update it just by dd'ing a new image over the partition.

How do I use "$ ssh -X <user@machine> <text editing program> <file to edit>" ? I can't do a web search for it because nothing comes up for "ssh -x remote execution" and so forth. I want to use a text editor on my desktop to edit some text files on my beaglebone, because it sucks using the terminal to copy and paste between different documents. I'd rather use gedit or SublimeText.

It looks like Sublime Text has a plugin for editing over SFTP, it's $20 though. Another option might be to use WinSCP to edit files w/ Sublime Text, I think it had a feature for that. Or maybe a Sublime Text build job that rsyncs your directory over ssh to the beaglebone. The way you described is probably doable too but it sounds like it would be annoying if you are working with multiple files.

What you're trying to do is X forwarding. I'm guessing what you're trying isn't going to work though. What you'd be doing is executing a program on the remote computer, in this casea the beaglebone, and showing the graphics on your desktop. But it sounds like what you're trying to do is use an editor on your desktop to edit a file on the beaglebone, which won't work. You'll need an editor installed on the beaglebone, but from looking at what that is, I'm guessing that's not possible.

Alternately, install sshfs on your workstation and just mount the folder from the Beaglebone locally. Then you can open the files with whatever local tools you want.

Baron Bifford posted:In Linux Mint, my external hard drive is mounted in /media/bifford. I thought it would be mounted in /mnt. Why is this so? What is /mnt for? The standard answer is supplied by the Filesystem Hierarchy Standard documents: http://www.pathname.com/fhs/ FHS 2.3 posted:/media : Mount point for removeable media FHS 2.3 posted:/mnt : Mount point for a temporarily mounted filesystem My interpretation: /mnt exists so that whenever you're rearranging your filesystem layout, salvaging data from a dying HDD, or doing anything else that requires mounting filesystems manually, there will be at least one mount point that is guaranteed to be available for you, so you don't need to create (as many) whimsically-named mount-point directories all over the place and then forget to remove them when you're done. /mnt is separate from /media so that whatever system is used to automatically mount and unmount removable media won't accidentally gently caress up your temporary mount(s) and vice versa.

Note that /media/ isn't used by the latest udev/systemd for USB media since it's seat-specific and is sort of a security leak to be global, so it's in /run/media/$USER/ instead. The FHS is outdated at this point. But did you expect anything else from the spec that still has /usr/X11R6 ?

This shellshock stuff has made me realize I don't really get what the shell is. I mean, I understand that it interprets commands I type in a terminal. I just assumed it's a binary sitting somewhere that something runs when I open a terminal in X or login to a GUI-less machine and that that binary presents me with a prompt and stuff. If that assumption is accurate, I'm not sure how I get from that information to it being a vector for remote people to run code another machine.

Well, you already know the language that the interactive shell uses. So why not build your system out of this language? It's a convenient way to plug multiple programs together! A shocking amount of programs actually believe this is a good idea and do this. They are wrong.

Thermopyle posted:If that assumption is accurate, I'm not sure how I get from that information to it being a vector for remote people to run code another machine. The first is when daemon/sevice accounts use /bin/bash as a login shell and have a mechanism for remote login that spawns it. For example, under ssh with command restriction, ShellShock can be used to bypass the restriction. The second, and more important, is when /bin/sh is symlinked to /bin/bash. Many programs call /bin/sh as a default shell to do various operations, including system(3) libc function which, in many cases wouldn't need to call a shell but does anyways. Specifically, some HTTP daemons call system(3) to execute a CGI script, which passes un-sanitized headers to the script via environment variables, which itself is fine except BASH goes and executes them. The latter point is particularly contentious as it's been recognized for a while that, while BASH is a decent interactive shell, it's kind of crummy for scripting unless you need BASH-specific features. Debian and Ubuntu long switched /bin/sh to DASH which doesn't suffer this bug. Others haven't because of the tendency for shell scripts to specify /bin/sh as an interpreter, but otherwise contain BASHisms that break if DASH is used as /bin/sh.
