I'm running libtorrent/rtorrent master (13.7) on raspi 3b+ with raspbian. I can download torrents under 4GB in size without any problems (for example debian netinstall at around 290MB). However downloading anything roughly bigger than 4GB will result in a hashfail every time. To clarify, the download of even big files finishes but when hashing the finished download it detects a hash fail. Sometimes as early as 200MB into the file (out of say a 4.6GB file). The downloads are saved to an external 4TB hard drive connected via USB and formatted with exFAT. The drive itself is encrypted using veracrypt.  At first I suspected it had something to do with the preallocate feature of rtorrent. I tried disabling it but the results are the same. I'm also not sure why the hash corruption is not caught mid download as every chunk should be checked separately. I don't think it's a hardware failure as the drive is new and has not shown problems otherwise. I have tried installing rtorrent from apt before which shows the same symptoms. I installed the self compiled version afterwards which is what I'm currently using.  Running rtorrent from my desktop on the same torrents that fail on the raspberry works flawlessly.

I recently purchased a 32GB USB 3 stick that was formatted FAT32.  I plugged it into my computer and attempted to copy a film onto it, the file was over 4GB however and it would not let me copy the file across because of the .  After some googling I found that I could format my USB stick to have an  format which would mean I could put files onto the stick greater than 4GB in size and the drive would work on both my Mac and my PC.  The problem with this solution is that my PS3 cannot detect the USB stick when it is formatted with exFAT.  I would like to know if there is a way I can have my USB stick formatted so it can have files greater than 4 GB and work on my PC, Mac and PS3.

Can anyone help me configure Transmission to download torrent files behind a proxy?  I have http_proxy set in my .bashrc.

I want to make a fresh new copy of a large number of files from one local drive to another.  I've read that rsync does a checksum comparison of files when sending them to a remote machine over a network.   Will rsync make the comparison when copying the files between two local drives? If it does do a verification - is it a safe bet? Or is it better to do a byte by byte comparison?

Here's my problem  I'm trying to do a cleanup of my hard drive, and I'm constantly seeing this scenario:  (1) Aggregate folder size: I check the folder size viewing properties right clicking the folder  (2) Individual folder/file sizes: I check the individual file/folder sizes belonging to that folder viewing properties on the individual file/folder sizes, and then adding them up (with hidden and system files shown).   These two figures are always different, sometimes by a large margin.   For instance, my C drive now, by method (1), shows a consumed space of 42.4 GB.   However, by method (2), by inspecting the respective files/folders, the total consumed space adds up only to 33.1 GB. This is a 28% discrepancy (over the smaller file size) and I have no idea where the rest of the space is going.   My hard drive is constantly in danger of being full (it's bootcamp on a mac with 50 GB of partitioned space), and there's not much I've got installed in terms of software, nor do I have large media files like movies, downloads, temp files, application temp files, torrents, etc.   Most of it's just consumed by the files in C:/Windows, but last I checked, I don't know enough to know which files to delete, and I've heard that you really can't do anything about the space boggling winsxs and system32.   Can you guys recommend a starting point to free up disk space?  Thanks!!  Baggio.

I have an old computer that can't handle a boot stick install, so i have to create an actual, old fashioned boot CD.  However, the image size for Ubuntu 12.04 is 732MB, which is too large for a CD, which can hold only 700MB.  The maintainers of Ubuntu 12.04 say the image size will never go over 700MB, and indeed, the download size seemed to be 689MB.  Brasero says it won't burn the CD because the file is too big, what's going on?

Not to long ago I was using only 35% of my HD. Just recently it shot up to 54% and my diskspace is 16gb so that's more then 3gigs that have been taken.  From what I remember I failed to build mysql, I installed gitolite which required me to build git from source which had a tons of dependencies (I think it was for building docs, I think I saw latex and other packages but I was drowsy when I was installing). I suspect that is what is taking the diskspace.  Anyways so far I deleted source folders I know I had and ran these commands. What else can I do? (3gigs is mighty)  sudo apt-get autoclean sudo deborphan | xargs sudo apt-get -y remove --purge     After doing the above i did ncdu and found that   Git itself was actually using 502mb in 152 files all in '/usr/local/libexec/git-core'. Who knew. I found it strange that most of those files are 4.6mb each... MySql was taking up 1+gb in my /tmp folder I accidentally made a copy of my mono src folder which has two builds of mono and is 1.7gb together.    After deleting the copy of src and an extra mono build (thats 2.6gb together) + the mysql in my temp folder df now reports 28% instead of 54% which makes me feel a lot better.  I'm still surprised git uses 502mb. On windows it uses 57mb (thats about 10xless). And the equivalent folder (C:\Program Files (x86)\Git\libexec\git-core) has all those apps as shortcuts to git. and git is only 1.2mb (not 4.6). Also i checked if the linux git-core folder were all links, i know they arent softlinks (i used the cmd find . -maxdepth 1 -type l -print0 | xargs -0 ls -ld)  I tried stat git, stat git-add and saw they had the same innode. So most of these files are hardlinks (i assume) of git. So git doesnt actually take up that amount of space.

So I'm checking the md5 hash of my files with this as my output:  657cf4512a77bf47c39a0482be8e41e0  ./dupes2.txt 657cf4512a77bf47c39a0482be8e41e0  ./dupes.txt 8d60a927ce0f411ec94ac26a4785f749  ./derpina.txt 15f63928b8a1d5337137c38b5d66eed3  ./foo.txt 8d60a927ce0f411ec94ac26a4785f749  ./derp.txt   However, after running find . -type f -exec md5sum '{}' ';' | uniq -w 33 to find the unique hashes I get this:  657cf4512a77bf47c39a0482be8e41e0  ./dupes2.txt 8d60a927ce0f411ec94ac26a4785f749  ./derpina.txt 15f63928b8a1d5337137c38b5d66eed3  ./foo.txt 8d60a927ce0f411ec94ac26a4785f749  ./derp.txt   From my understanding, only one of either derpina.txt or derp.txt should be showing up since their hashes are the same. Am I missing something? Can anyone enlighten me as to why it outputs like this?

I am connected to a linux system with SSH in my college. I found that  is a console alternative of bitorrent. I have downloaded the tar.gz source but to compile/install it needs sudo access  Is there a way to install the program without sudo access?  I don't know a lot about linux and cannot make  work with ctorrent.

This is a situation I am frequently in:   I have a source server with a 320GB hard-drive inside of it, and 16GB of ram (, but as this is an issue I run into frequently on other machines as well, I would prefer the answer to work on any "reasonable" Linux machine) I have a backup server with several terabytes of hard-drive space (, see disclaimer above)   I want to transfer 320GB of data from the source server to the target server (specifically, the data from /dev/sda).   The two computers are physically next to each other, so I can run cables between them. I'm on a LAN, and , which means my network speeds should "ideally" be 1000Mbit, right? Security is not an issue. I am on a local network, and I trust all machines on the network, including the router. (optional) I don't necessarily need a signed checksum of the data, but basic error checking (such as dropped packets, or the drive becoming unreadable) should be detected rather than just disappear into the output.     I searched for this question online, and have tested several commands. The one that appears the most often is this:  ssh user@192.168.1.100 'dd bs=16M if=/dev/sda | gzip' &gt; backup_sda.gz   This command has proven too slow (it ran for an hour, only got about 80GB through the data). It took about 1 minute and 22 seconds for the 1GB test packet, and ended up being twice as fast when not compressed. The results may also have been skewed by the fact that the transferred file is less than the amount of RAM on the source system.  Moreover (and this was tested on 1GB test pieces), I'm getting issues if I use the gzip command and dd; the resulting file has a different checksum when extracted on the target, than it does if piped directly. I'm still trying to figure out why this is happening.

When running apt full-upgrade or apt update I'm getting several logs that are more or less the same as this one, where there is an identical filesize, SHA1 and MD5 but different SHA256:   E: Failed to fetch store:/var/lib/apt/lists/partial/jp.archive.ubuntu.com_ubuntu_dists_focal_main_binary-amd64_Packages.xz  Hash Sum mismatch    Hashes of expected file:     - Filesize:5826751 [weak]     - SHA256:af226b4496cbb524bd4814d102047ae77769836203274dffc91cb543d5da13cc     - SHA1:aef5c36ce45bd5c3154a1bb03c62b6cfb33e2bc6 [weak]     - MD5Sum:7ef83228ec207df10acac48fbdd81112 [weak]    Hashes of received file:     - SHA256:e2c7fc5a2d86f75f03612fec614dcf84d3d502976558fbe40928c1dd120bb05e     - SHA1:aef5c36ce45bd5c3154a1bb03c62b6cfb33e2bc6 [weak]     - MD5Sum:7ef83228ec207df10acac48fbdd81112 [weak]     - Filesize:5826751 [weak]    Last modification reported: Thu, 23 Apr 2020 16:40:26 +0000    Release file created at: Thu, 23 Apr 2020 17:33:17 +0000   Whereas others have the same MD5, but different SHA1 and SHA256:   E: Failed to fetch http://jp.archive.ubuntu.com/ubuntu/pool/main/l/linux/linux-headers-5.4.0-29_5.4.0-29.33_all.deb  Hash Sum mismatch    Hashes of expected file:     - SHA256:edde13dcd52c51e2404d37731948d491e6e215b22f599239326809754f8d5633     - SHA1:3e46354d6aaa92f82d5392a80f6b72c3fcc78a91 [weak]     - MD5Sum:4ccf38c666c836f29fc3602314de47b9 [weak]     - Filesize:10936232 [weak]    Hashes of received file:     - SHA256:9af606f85850ba3010ac8743f62dca91bbef3e5e60da5a7df62dac53eb5a4fb7     - SHA1:61c842d896676ac9af0fef9f9f48bc4a3c39cce6 [weak]     - MD5Sum:4ccf38c666c836f29fc3602314de47b9 [weak]     - Filesize:10936232 [weak]    Last modification reported: Thu, 30 Apr 2020 08:23:38 +0000    This problem is similar to what is asked , and indeed I tried several of the solutions offered there (and elsewhere) but they did not help. However I am wondering specifically about why the SHA-1 and MD5Sum are identical, and only SHA256 is different. Does this mean that there is a security problem somewhere along the line? Or is my system reading SHA256 incorrectly? Something else?  Thanks

I'm in the process of recovering files from an accidentally formated Ext4 partition using Photorec. It had about 300Gb of data, of which I've already got hold of about 30Gb.  So far, it seems to me that the recovery of RAR-compressed files has been much more successful than the recovery of individual uncompressed files and ZIP compressed files - in the sense that a lot of recovered files/zips were unreadable, and pretty much all of the RAR files were intact.  Is there such a relation? Are RAR-compressed files really less prone to corruption and thus easier to recover?

I run into problem when tried to install Ubuntu 11.04 on Windows 7 using wubi installer . It downloads the image for sometime and ends up with the error that says   Permission denied: for more details see the log file  In the log it seems to be like  DownloadError: Problem connecting to tracker - urlopen error (10060, 'Operation timed out')  but my network is good and I checked it.  Tried using wubi several times, but ends up with same problem.
