Someone has sent this file to me and telling me that something is wrong with this file, the file name is winmail.dat. I was wondering what's is contained in the file and as usual I check on the file type -
winmail.dat: Transport Neutral Encapsulation Format
I haven't seen this file type before, while I'm wondering why, wiki seems to answer my question in pretty details -
Okay, so I have never been a Outlook user, now I need to look at how to decode the file properly, I found this simple trick using tnef,
Available versions: 1.3.3 1.3.4 ~1.4.3
Installed: 1.3.4(18:07:41 02/22/07)
Description: Decodes MS-TNEF MIME attachments
Eix is gentoo tool that similar to debian apt-cache which allows you to search for the applications in the portage, installing it is pretty quick -
shell>emerge -v tnef
Once it is installed, I can easily list the attachment in the TNEF file -
shell>tnef -f winmail.dat -t
To extract the attachment and save the message in the body into the desired directory, I just need to run -
shell>tnef -f winmail.dat --save-body -C tnef-dir/
shell>/tnef-dir $ ls -al

Here's the partial contents in css.php that looks interesting -
passthru("perl /tmp/nst_perl_datapipe.pl &");
passthru("perl .nst_datapipe_tmp/nst_perl_datapipe.pl &");
I just learned the new file format and the way to read TNEF file without using Windows, have fun!
