    Guy tries to prove Linux gets malware too. Only proves he's an idiot.

    Yep, good for you, or you would have received all the heat from the Interwebs.

    Well, not at all:

    On "Mythbusting Linux", *.exe and *.dll are windows extensions. If those malicious binaries are being accessed by the application in question, it must be using Wine or some equivalent to execute it. It's true that Linux can get malware, but in this case it looks like you have Windows malware.

    I also find it troubling that you've disabled comments. Is it to prevent yourself from being debunked?



  • Can someone post a list of all things he's :fa_quote_left: debunking :fa_quote_right: :question:


  • BINNED

    Well, he's right, that directory has malware in it. And I can get malware right now, not a big deal.

    MYTH: Linux doesn't need (manual?) defragmenting

    Dunno.

    MYTH: Linux doesn't need restart after update

    He's right there.

    MYTH: You can move Linux HD from one PC to another, and it will boot

    Who cares?



  • @cartman82 said:

    MYTH: Linux doesn't need (manual?) defragmenting

    It's not OS-specific thing but FS-specific thing.

    @cartman82 said:

    Technically, it doesn't. But in practice, it does.

    @cartman82 said:

    Depends on hardware configuration, bootloader settings and /etc/fstab.

    Basically, he's not necessarily wrong - he's just being pedantic dickweed.

    for most things yes. fr some things (like kernel updates) it's probably a good idea

  • @cartman82 said:

    I keep my personal desktop environment on a USB hard disk that boots into Debian on whatever computer I happen to be using that day, so I know from first-hand experience that this works extremely well.

    Never had it fail with a SATA or IDE installation either, for what it's worth.


  • BINNED

    Well, Debian uses device names, at least if you use LVM:

    ❯ cat /etc/fstab 
    # /etc/fstab: static file system information.
    #
    # Use 'blkid' to print the universally unique identifier for a
    # device; this may be used with UUID= as a more robust way to name devices
    # that works even if disks are added and removed. See fstab(5).
    #
    # <file system> <mount point>   <type>  <options>       <dump>  <pass>
    /dev/mapper/vg1-root /               ext4    errors=remount-ro 0       1
    /dev/mapper/vg1-home /home           ext4    defaults        0       2
    /dev/mapper/vg1-swap none            swap    sw              0       0
    /dev/sr0        /media/cdrom0   udf,iso9660 user,noauto     0       0
    


  • The only potentially problematic name there is /dev/sr0, but that almost always resolves to an optical drive of some sort; never actually had it cause a problem.

    These days you can leave that line out anyway, and rely on systemd shenanigans instead. It seems to work.

  • @cartman82 said:

    There's malware in the "money shot" you posted.

    It's not executing, but that's not the claim. PEDANTIC DICKWEEDERY!!!



  • The day malware writers get interested in Linux, we'll just change the libc ABI very slightly and recompile the world.

    The thing that kept grating on me was "universal unified identifier".

    The guy is an asshat. He doesn't know he is a moron, and those are the most dangerous types.



  • @blakeyrat said:

    It's Windows malware.<!-- I may be taking bait here? Or maybe you somehow legitimately did not grasp that those are not linux executables. -->



  • @Gribnit said:

    Yesssss...


  • BINNED

    About the fragmentation issue:

    This is my /home drive. It wasn't formatted nor defragmented in any way that required my attention, if at all, since I got this machine which is now coming up on two years. It's stores all my settings, downloads directory which keeps getting filled up and then cleaned up, and a bunch of files of differing sizes. This thing saw some use is what I'm saying:

    onyx@jarvis ~> sudo fsck -fn /dev/sda6 
    fsck from util-linux 2.26.2
    e2fsck 1.42.13 (17-May-2015)
    
    <snip bunch of complaints that are there because the filesystem is currently mounted>
    
    /dev/sda6: 1301439/42950656 files (1.1% non-contiguous), 157972098/171779584 blocks
    

    1.1% ? PANIC!



  • @blakeyrat said:

    It's not executing, but that's not the claim

    It can't even reasonably execute. This is not proper pedantry.



  • The claim is "Linux can't get malware".

    Is that a Linux install? Yes.

    Are those files malware? Yes.

    Are those files in the Linux install? Yes.

    The only possible deduction from this is that that Linux install has somehow acquired malware, which contradicts the thesis, meaning the thesis is wrong and must be discarded. I don't see how you are having difficulty with this, unless your love of Linux has blinded you to basic logic (admittedly, a prerequisite to loving Linux).



  • You think /var/tmp is stuff from the install?



  • If you printed out a hex dump of the malware and set it on a wooden table, did the wooden table acquire malware in any meaningful, non-pendantic dickweed way that someone other than a Windows user would understand?

    8/10, would read again.

    @Kian said:

    I believe more accurately the claim is "malware doesn't run on Linux" with the caveat of "unless you do something really stupid" and the qualifier of "most people who run Linux aren't really stupid".

    But most of us will settle for "Linux doesn't get infected with malware" and to be infected it has to be running. That malware was not running. I can download MS Office on a Linux box, that doesn't mean that Linux gets MS Office.

  • Discourse touched me in a no-no place

    Isn't not being able to run certain apps one of the standard complaints about Linux? Next time someone complains about that, we can just refer them to @kian. :trollface:



  • @Gribnit said:

    You think /var/tmp is stuff from the install?

    All the Linux distributions I make have a /vat/tmp directory stuffed with .exe, .dll, .bat and .com malware files. Why wouldn't I believe others could conceivably do it too?

    But no, I don't think it came with the install. I think, as I deduced above, that it somehow acquired it.

    Gremlins. Gotta be gremlins. Or your incompetent younger brother stealing it and booting it from a Windows To Go stick to watch porn, because surely you couldn't be that incompetent. Oh, you don't have a younger brother? Huh. I guess that must be your Windows To Go stick.

    I don't see why. If he made his own Linux distro he can put stuff wherever he wants.

    What put it there? The simplest explanation seems to be that your browser was exploited, but the payload was a windows payload, so you lucked out. Still, software that you didn't control seems to have written to your file system (albeit in a very innocuous location).



  • @Jaime said:

    Even simpler: he just downloaded and saved it there. Which removed letters n and t from your next sentence.

    The only FS family that ever really needed that was FAT.

    @cartman82 said:

    You can configure systems to work that way, but most of the time it's simpler to reboot.

    @cartman82 said:

    Mostly true. (Except if the BIOS is being an ass.) If you've got some exotic hardware configuration involved, then you might have problems. You'd likely have similar troubles with other OSes too. I wouldn't expect to be able to pick a disk out of a RAID 5 array and be able to boot off it on some other system… :smiley:



  • @dkf said:

    You still need to defragment your hard drive every now and then but it's not nearly as pronounced as it is in FAT and it's family of FS. Even ssds need it every now and then but you won't see the performance gains that you see with defragmenting FAT mechicanal drives.



  • @dkf said:

    MYTH: Linux doesn't need (manual?) defragmenting

    Dunno about that. In my experience, running MyDefrag against a Windows 7 installation (NTFS) that's been left to its own devices for a year or so will reliably make it boot about 30% faster and make noticeable improvements to application launch speed as well.



  • @DogsB said:

    Do you run a RAM defragger too?

    Aw I haven't seen one of those in years.

    No idea about ram but microsoft have some stuff to say about defragging ssds.
    This articule sums it up nicely. The TLDR is fragmentation does occur on ssds but the performance is so high compared to mechanical drives that you don't really notice.



  • I'm afraid you arrived at the right conclusion, but for entirely wrong reasons.



  • @Gaska said:

    I'm afraid you arrived at the right conclusion, but for entirely wrong reasons.
    Would you mind articulating your reasoning. I always like to excise faulty reasonings from my own thinking.



  • Fragmentation doesn't matter on SSDs because there's no seek time.



  • @PleegWat said:

    Fragmentation doesn't matter on SSDs because there's no seek time.
    Seek time is significantly reduced not eliminated. Lets be accurate here.



  • For all intensive porpoises, it's eliminated. It's so low it stops being the bottleneck in disk reads - so any attempts to optimize it, e.g. defragmentation, have no effect beause the bottleneck is elsewhere.

    Defragmentation is optimization, and thus it should follow the rules of optimization:

    1. Don't optimize.
    2. (Experts only) Don't optimize yet.


  • And defrag will hardly be worthy the life reduction for an ssd



  • @dkf said:

    HFS needed it also. HFS+ (practically speaking) does not.
