Has anyone tried using SilentEye on Slackware?

DarkReZus · 08-25-2011, 01:35 AM

cmake v2.8.5 is required to find zlib and other dependencies. Debian/Ubuntu distribution just change path "/usr/lib/" to "/usr/lib/i386-linux-gnu/". So if slackware didn't change libraries folder cmake 2.8.3 is enough ^^

Ponce, "Selected media doesn't have enough space to encode your message!" means that your image (2d01dda.jpg) doesn't have any pixel to hide your message. According to log you can use 9 embedded bits per pixel (3bits per color). Just try with a bigger image or a shorter message to hide.

EDIT: after some initial self-caused trouble, all ok with a bigger image

spudgunner, can you try if this works for you?

I was pondering about the file positioning of the resulting package

Code:

/usr/share/silenteye/silenteye
/usr/share/silenteye/version.xml
/usr/share/silenteye/modules/
/usr/share/silenteye/modules/libsecryptoaes256.so
/usr/share/silenteye/modules/libseformatwav.so
/usr/share/silenteye/modules/libseformatjpeg.so
/usr/share/silenteye/modules/libseformatbmp.so
/usr/share/silenteye/modules/libsecryptoaes.so
/usr/share/silenteye/libsef.so

following other packages organization, would be nice if we can have something like this (instead of the setup in a folder), maybe also (but not essential) with a make install DESTDIR=$PKG, for packaging

Code:

/usr/bin/silenteye
/etc/silenteye/version.xml
/usr/lib$LIB_SUFFIX/silenteye/modules/
/usr/lib$LIB_SUFFIX/silenteye/modules/libsecryptoaes256.so
/usr/lib$LIB_SUFFIX/silenteye/modules/libseformatwav.so
/usr/lib$LIB_SUFFIX/silenteye/modules/libseformatjpeg.so
/usr/lib$LIB_SUFFIX/silenteye/modules/libseformatbmp.so
/usr/lib$LIB_SUFFIX/silenteye/modules/libsecryptoaes.so
/usr/lib$LIB_SUFFIX/silenteye/libsef.so

Wow, nice work. I didn't need it THAT badly, more curiosity than anything, but I'll take it.

Pounce, the slackbuild you've made seems to build properly, however, when I try to start silenteye from the terminal, this error comes up:

Code:

bash-4.1# silenteye
**
GLib-GIO:ERROR:gdbusconnection.c:2279:initable_init: assertion failed: (connection->initialization_error == NULL)
Aborted

I'm using Slackware -current with rworkman's xfce 4.8 packages in a VM. I will try this out on a real computer tonight sometime and see if anything different happens.

EDIT: Apparently I spoke too soon. After posting this, I went to close my terminal and shut down my VM and realized I was still root in my terminal. I exited from root and tried it again and it worked. However (and I don't think this is pounce's fault, but some of the other problems people were reporting about the project being 'young'), the program doesn't encode and/or decode messages when trying to used the 'compressed data' setting and it doesn't decode 100% accurately. My test phrase was "Will this decode properly?" and I got back "Vill this decode prop".

Excellent job on the slackbuild though!

@Ponce, i will work on the packages organization (make install) next week :-) next step will be to include your slackbuild in "install/linux/slackbuild" of the poject's source.

@spudgunner, can you give me your configuration in order to track the bug :
* original image dimension (width,height)
* plugin : BMP/JPEG?
* advanced plugin options
* log file for encoding and decoding process in debug mode
(could you create a new issue at http://forge.silenteye.org/projects/stegano/issues? registration needed)

But yes, project is young and I need to make a lot of code optimization. Thanks for your help :-)

ponce · 08-25-2011, 03:35 PM

I'll surely modify it after the addition of the make install routines, so maybe it's better to include it later

spudgunner · 08-25-2011, 03:42 PM

I will try to get that done tonight (if not tonight, over the weekend for sure). I want to test it out on a proper computer too, altough it should work fine in the VM.

spudgunner · 08-28-2011, 09:14 AM

So I've signed up and submitted the bug report as request. I discovered some interesting things when I ran this on an actually computer (vs a VM).

I've been doing my small amount of testing using a jpeg image with the jpeg encoding format with default settings (one of which is to use compression). Everything works with different phrases except the phrase "Will this be decoded properly?". I tested this and a couple of other phrases using uncompressed data and it worked fine.

All related files (picture, log files, terminal output) can be found at the project website for those interested.

DarkReZus · 08-29-2011, 01:49 PM

New implementation is available on svn branche, you can now change all application paths (see README_UNIX) :

Code:

$root> ENABLE_PACK=1 ENABLE_MODULE=1 LOGPATH_USERHOME=1 CONFPATH_USERHOME=1 ENABLE_GNOMEMENU=1 cmake .
$root> make
$root> make install
or
$root> make install DESTDIR=$PKG

Thank you

Otherwise have you tried to increase "k" value ?

ponce · 08-30-2011, 11:52 AM

tried now revision 151 and all it's pretty much ok

applied just a small patch to CMakeLists.txt or I got "make install" get between the package files also

Code:

/root/
/root/.silenteye/
/root/.silenteye/silenteye.conf

this way a default configuration file is installed in /etc (or in CONFPATH_VALUE, if specified) when selecting CONFPATH_USERHOME=1

this is the package content. As you can see the slackbuild got pretty much cleaner too

Thanks a lot DarkReZus!

Thanks ponce!!
Your build worked perfect!!

system:
Slackware64-Current Multi-Lib

DarkReZus · 08-30-2011, 03:32 PM

r152 committed with your small patch (a little modified).
also push "install/linux/slackware" with your contribution. I will update it for official 0.4.2 release. Keep you in touch.
good job
