Curiouser and curiouser. To summarize: 1. On my main BLFS system, 32 bits 1.1. I normally download a file by clicking it with left button. 1.2. I normally download using my (32-bit) Chromium. 1.3. As far as RSYNC is concerned (however, see below for Ubuntu) this gets me the "terribly wrong", 3287040 byte file. 1.4. RSYNC downloaded through any other method know to man like, wget, Firefox, Win 10/IE (perish the thought!), etc., gets me the "correct" file (892724 bytes). % ls -og 3287040 2016-02-14 15:15 rsync-3.1.2.tar.gz (chromium) 892724 2015-12-21 15:23 rsync-3.1.2.tar.gz.1 (all the other) % md5sum * 1be3ec9421f23e8eb7a06957992f6604 rsync-3.1.2.tar.gz 0f758d7e000c0f7f7d3792610fad70cb rsync-3.1.2.tar.gz.1 (any surprize now?) 1.5. This is really a big head scratcher. Once untarred, the two files create absolutely identical directory trees. As a summary of the _many_ checks for identity: % du -bd 1 rsync-3.1.2-3K 7810 rsync-3.1.2-3K/testhelp 497004 rsync-3.1.2-3K/zlib 84142 rsync-3.1.2-3K/testsuite 7270 rsync-3.1.2-3K/m4 18546 rsync-3.1.2-3K/doc 49886 rsync-3.1.2-3K/support 198981 rsync-3.1.2-3K/lib 62321 rsync-3.1.2-3K/packaging 99440 rsync-3.1.2-3K/popt 3162975 rsync-3.1.2-3K % du -bd 1 rsync-3.1.2 7810 rsync-3.1.2/testhelp 497004 rsync-3.1.2/zlib 84142 rsync-3.1.2/testsuite 7270 rsync-3.1.2/m4 18546 rsync-3.1.2/doc 49886 rsync-3.1.2/support 198981 rsync-3.1.2/lib 62321 rsync-3.1.2/packaging 99440 rsync-3.1.2/popt 3162975 rsync-3.1.2 (after tar -xf ..., I named one directory ... -3K, so they can coexist) "Sparse" files? (a cmp -l of the two tarballs crashes my machine :) -------- 2. For comparison, on my ubuntu 15.10, 64-bit using Chrome 48.0.2564.109 (latest) % ls -l 320459924 Feb 14 18:25 qt-everywhere-opensource-src-5.5.1.tar.xz 3287040 Feb 14 18:21 rsync-3.1.2.tar.gz Note: the BLFS book gives the qt file size=306MB -> OK % md5sum * c2a249e8795d45200d997d96860d0353 qt-everywhere-opensource-src-5.5.1.tar.xz 1be3ec9421f23e8E7a06957992f6604 rsync-3.1.2.tar.gz PUZZLEMENTS 1. Why the HUGE size difference on Chrom(ium) download of RSYNC? 2. Why not with other files (I picked qt-5.5.1, randomly, on a whim)? 2.1. In all these years, always normally using Chromium, I _ never _ have run into a crazy size -> MD5 situation. Hoping you've had a good Valentine's day (to top it all off, my red roses are already wilted - bad MD5, no doubt), -- Alex
