Installation on ArchLinux

[noraj]

On arxsys there is instruction to install dff from sources but all dependencies are given for Debian.

Can you give a ArchLinux install guide or only depencies will be enought.

Thanks

[blshkv]

and this is how you should realise NOT to provide dff-build.sh. The software should have a proper CMakeLists.txt (which this project has already). Let distro maintainers do it right.

P.S. I'm creating an ebuild for Pentoo Linux right now, and it will look very similar with ArchLinux packages

Hey @noraj1337, do take a look at the PKGBUILD I just published on the AUR.
https://aur.archlinux.org/packages/dff-git/

Let me know if you encounter any problems building it.
There may likely be missing dependencies, but yeah, just inform me.

[blshkv]

Gentoo/Pentoo ebuild is here as well:
https://github.com/pentoo/pentoo-overlay/tree/master/app-forensics/dff

[blshkv]

As you can see, both build packages are UGLY. As I said, DFF developers should review all patches, sed changes, etc and fix DFF properly.

[jarylc]

@blshkv I have to agree, some of their codes aren't very up to date. One example is the latest ICU not being detected in their old yet customized FindICU.cmake. Other problems include python3 and python2 conflicts.

My headache for the past 4 days is almost over...

I placed a pull request to the repo and tested building on both Debian & ArchLinux.

[blshkv]

@jarylc 4 days?!.. wow ... out of curiosity, I've looked at your PKGBUILD .. It looks like arch linux does not provide any utilities and that's why you have to do everything manually using bash commands.

It took me an hour probably. Yes, the same problem with ICU, so I just commented out 2 depreciated lines . No problem with python because it is handled by a distro eclases. Well, except linux_launcher.sh which is python (not a shell) script apprentely. SICK!

One of the hardest problem was broken code in dff-api/search/CMakeLists.txt file . It does not install __init__.py file if TRE library not found. That breaks the tool (does not start) and it took me awhile to figure it out ..

[noraj]

@jarylc : I commented your AUR package: https://aur.archlinux.org/packages/dff-git/#comment-578098

Install successfully from an up-to-date system.

But some (non-blocking) python import error when launching dff-gui:

libpng warning: iCCP: known incorrect sRGB profile
ImportError: No module named pyregfi

  File "/usr/bin/dff/api/loader/loader.py", line 239, in __load
    module = imp.load_module(modname, file, pathname, description)

    from hive import RHive

  File "/usr/lib/python2.7/site-packages/dff/modules/databases/winreg/hive.py", line 15, in <module>
    import pyregfi

You are missing reglookup (and may be others). See my ebuild.

P.S. I'm working with reglookup upstream on Scons improvements, see pentoo/pentoo-overlay#145

[jarylc]

@noraj1337 @blshkv

Also Reglookup on the AUR currently only installs for Python 3, we need to copy the site-packages over to Python 2 libraries for support.

I have no control over that package as it's maintained by someone else. I could make python2-reglookup, but that would be redundant. I'll wait for the maintainer's reply or action to my comment.

@blshkv I'm not sure if what you are pushing to Scons repo would fix this as I've not read it yet. Will take a look later.

@noraj1337 Look at my reply and pinned comment on the AUR on how to fix this.

[blshkv]

Ha! I didn't realise that this old (2011) tool supports python3 as well. Thanks, fixed!

[noraj]

I see dff is included in blackarch now : https://blackarch.org/forensic.html

But both dff from blackarch and from git doesn't work now. There is a segmentation fault.

$ dff-gui
libpng warning: iCCP: known incorrect sRGB profile

And I have some python errors when asking help:

update: this is DFF 1.4.0 - dff-183.d40d46b-1

[jarylc]

@noraj1337 oh DFF got updated to 1.4.0? Seems like I need to recreate the patch files again if changes were made.

edit: oh, I don't think it was a DFF update that caused it because it wasn't updated... Probably a new update to either python 2, qt4, swig or any other build tool that caused it... I'll check it out when I have the time.

EDIT: I found some problems regarding the latest version of python2-pyqt4. Reference http://stackoverflow.com/questions/37604532/python-2-7-11-importerror-cannot-import-name-qtwebkit-kali-linux-debian-8#37616466

I'll need to find time to perform the hard fix.

Hi guys!

Sorry for this long delay but we had lots of "business" stuff to manage and as you may have seen we are currently closing ArxSys. However, that does not mean it's the end of the development of DFF. We will soon release everything on github and there will be huge changes which may resolve your issues. We are going to work on this merge during the following days.

[noraj]

@udgover Good news for DFF and sorry for ArxSys.
