Software :: Convert An MD5 Hash Into Shadow Format?
Nov 28, 2010I am trying to use John the Ripper but it doesn't take regular MD5 hashes, only shadow MD5 hashes. For example this hash: 900150983cd24fb0d6963f7d28e17f72 (which, decrypted, is 'abc') within a text file, John the Ripper does not detect because it is not shadow format. How can I convert this MD5 hash into shadow format?

Sep 24, 2009I am trying to write a remote access module. Is there any function in linux where I can give string (password entered by user) and compare it with the actual user password stored in /etc/shadow.

Aug 11, 2010i need to change a binary file, let's say to find and replace username:
find string: "/home/name/bla-bla-bla/ "
new string: "/home/anewname/bla-bla-bla/ "
i can do it, for example, in emacs (hexl-mode), but interesting in writing a script instead. it will be much more better for me if i could do it automatically. is there an analog of: sed 's/string1/string2/g' ? P.S. the best way is to recompile the binary files i have, but there are no sources available.
Programming :: Replace 2nd Occurrence Of A String In A File - Sed Or Awk?
Apr 5, 2010I know how to replace a particular instance (say 3rd one) of a word in a line using sed based on the sed one-liners. However I would like to replace a particular instance of a word in the entire file.
For example, here is a file:
Code:
John
Betty
Jack
Ron
Jack
Paul
So now I would like to replace the second instance of Jack (in red color) with "Rob" (for example). Not quite sure how to do that? I tried couple of things from here but they did not work.

Programming :: Sed Doesn't Accept Variables To Replace In File
Mar 17, 2011[code]...
The variables are clean and available in my script. No prob. $old is an IP-address of a server, $new as well. replacement-file is an xml-file (the ip-address to be changed is within an xml-tag). It should be trivial, but it isn't. I spent the last 3 hours reading about the problem, trying several different 'solutions' or workarounds. It should work, the '"' should take care that the variables get expanded, but whatever I try the old server IP isn't replaced.

Feb 25, 2011Code:
#!/bin/bash
VARR=`cat /proc/asound/cards | grep HDMI | cut -c 1-2`
VARX="defaults.ctl.card $VARR"
VARY="defaults.pcm.card $VARR"
FILE1="alsa"
FILE2="alsa.new"
echo $VARX
echo $VARY
sed "s/defaults.ctl.card*/'$VARX'/g" $FILE1 > $FILE2
This is what I have right now. Well, I thought I knew sed, and apparently I don't... I tried writing this for someone else, and this has given me trouble, so since the user pretty much figured it out on his own, here it goes.
Say VARR=1, so VARX and VARY contain the above text, appended by 1.
What I am trying to do is replace the text "defaults.ctl.card 0" by VARX and "defaults.pcm.card 0" by VARY. The contents of FILE1 is the file being used to search for both text fields, and FILE2 is the output file. I tried using single quotes, double quotes, and a mixture of both, and no go whatsoever. So my question... What is the proper way of searching for text within a file and replacing with a variable?
