I was wondering if anyone would be able to shed some light on how a file could end up with inconsistent md5sums on Gluster backend storage. Our configuration is running on Gluster v3.1.5 in a distribute-replicate setup consisting of 8 bricks. Our OS is Red Hat 5.6 x86_64. Backend storage is an ext3 RAID 5. The 8 bricks are in RR DNS and are mounted for reading/writing via NFS automounts. When com...

Hello, i am getting the following error in CentOS 64 bit with php 5.2 I cant get mysql functionality running and the ioncube loader Please help, i am very desperate Here is my output: [root at host ~]# php -v Failed loading /usr/local/ioncube/ioncube_loader_lin_5.1.so: /usr/local/ioncube/ioncube_loader_lin_5.1.so: undefined symbol: zend_unmangle_property_name_ex PHP Warning: PHP

I noticed that ext3 filesystems are modified if mounted read-only: # mke2fs -j /dev/hdb1 [...] # md5sum /dev/hdb1 > MD5SUM # mount -t ext3 -o ro /dev/hdb1 /mnt/test1 # umount /mnt/test1 # md5sum -c MD5SUM md5sum: MD5 check failed for '/dev/hdb1' On examination of a block-for-block copy of 'before' and 'after' images with od and diff, I believe that the changes are the tra...

Does anyone know in centos how to create an md5sum list based on the current rpms that I have installed right now on my box? I tried something like rpm -q -v | md5sum >> list but didnt work. Andrew

There are known Collision Attacks for the MD5SUM method of hashing, so it is possible to modify a file and make it have the same MD5SUM as another file. See this link for details on Collision Attacks: http://en.wikipedia.org/wiki/Collision_attack Recommendation from the US-CERT concerning MD5SUM hashes: http://www.kb.cert.org/vuls/id/836068...

I'm new to this list, so feel free to update me on any rules that I seem not to be familiar with. I'm looking at some strange behavior on a _very_ barebones installation. I'd like to get some feedback on possible logical explanations. * What I'm seeing: The md5sum of all of my binaries in /usr/bin and /usr/sbin are changing exactly one hour after installation of CentOS-4.3. The sizes of the files are increased, with minor changes visible at the beginning of the files, and a large chunk added to the end. Other files are also changing (under /usr/lib for exa...

AFAIK there is no hashing utility in base R which can create hash digests of arbitrary R objects. However, as also described by Henrik Bengtsson in [1], we have tools::md5sum() which calculates MD5 hashes of files. Calculating hashes of in-memory objects is a very common task in several areas, as demonstrated by the popularity of the 'digest' package (~850.000 downloads/month). Upon the inspection of the relevant files in the R-source (e.g., [2] and [3]), i...

R-help I have installed R 2.0.0 ( Windows) on my machine and had several 'crashes' while working on it. I have reinstalled a couple of times and still got strange behaviour from time to time(screen goes white and no prompt is printed out,,,) Last time I have reinstalled I checked the md5sum.txt (md5sum output for the setup program and went O.K) and also Md5 from which I paste a piece of output : . . md5sum: library/utils/man/utils.Rd.gz: No such file or directory library/utils/man/utils.Rd.gz: FAILED open or read . . . md5sum: library/tools/man/tools.Rd.gz: No such file or directory...

If md5sum --check did not return an error with a truncated file, then the file was likely broken to start with. I think the chances of a corrupted file generating the same md5sum is close enough to 0 that you will never see it in a life time. Also, you lost me on storing the md5sum value at the begging and...

...y first post, although I have looked at the archives. I haven't found an answer to this in the archives, so I thought I would post it here. I've downloaded the DVD iso for CentOS-3.1 from BitTorrent, and I'm leaving my torrent open for another day or so to help out. I see there is an MD5Sum file for the torrent file, but I can't find one for the DVD ISO file itself. Have I overlooked something, or can we get one added to the master MD5Sum file? Maybe BitTorrent takes care of checking the hash, but it would be nice to confirm after a download is done. Here's what I get as th...

tools::md5sum gives a warning if it receives a directory as an argument on Unix but not on Windows. >From what I understand, this happens because in Windows a directory is not treated as a file so fopen returns NULL. Then, NA is returned without a warning. On Unix, a directory is treated as a file so fopen d...

Hi, If I do an md5sum across 4 machines all running Centos5-x86_64 on /bin/bash why does it show a different checksum ? -> ssh box4 md5sum -b /bin/bash 53d2152059125e221a38099369e5777e */bin/bash -> ssh box6 md5sum -b /bin/bash e22fb934b0a4a840a330f47559d27205 */bin/bash -> ssh box5 md5sum -b /bin/bash 3...

...9% percent of the R developers do at least as an indirect dependency.) The point is that a) digest is a wonderful and very stable package, but still, it is a user-contributed package, whereas b) 'tools' is a base package which is included by default in all R installations, and c) tools::md5sum already exists, with almost all building blocks to allow its extension to calculate MD5 hashes of R objects, and d) there is high demand in the R community for being able to calculate hashes. So yes, if one wants to use all the utilities or the various algos that the digest package provides, on...

I have a server that is undergoing some patching soon and would like to make note of any files that have changed after the patching is complete. Can you recommend a tool that uses md5sum snapshots to do a quick before and after test, showing anything that's changed on a particular file system?

I get c1279b77fcccf40379f59a83523a440e *R-2.2.0-win32.exe but I see e8bdf765fe8013129045314c8e2605fd *rw2011.exe on several USA mirrors.

Hi all, I downloaded the 5.4 x86_64 DVD ISO this morning (CentOS-5.4-x86_64-bin-DVD.iso). However, the md5sum and sha1sums both don't match what's in the md5sum.txt or the release notes (http://wiki.centos.org/Manuals/ReleaseNotes/CentOS5.4). I downloaded two ISOs from two different mirrors, RIT and ANL, and both ISOs have the same checksums (match each other), which are different from the publish...
