If you run fix-splash on a backtrack installation and get:
$ sudo fix-splash

I am too lazy to restore the old version of this file from my old website (it was hosted for years on mambo and I am just too lazy to do the db conversion). Anyways, this website serves a couple of purposes, first is to keep some of my own notes handy and second to help others. With that in mind, here is a collection of tips on using john the ripper:
Prepare Linux Shadow Passwords
umask 077
./unshadow /etc/passwd /etc/shadow > mypasswds
Lets face it, John the Ripper has been around a long time and the reason its been around a long time is because its damn good at cracking passwords. Yea, hashcat and oclhashcat are great for gpu cracking, but it doesn’t support as many algorithms as JTR. So, imagine my surprise when I fire up John The Ripper on backtrack 5 64 bit and find out it is using a single CPU. That is letting a potential 75% of my system sit there wanting to do something. Luckily the fix is easier than fixing a sandwich.
If you already have jtr installed, you may want to see my john tips article.
First, lets grab the jumbo sourcecode….
I created this because I always forget the command to enumerate snmp and I am often too lazy to read man pages

read SVRIP

# This fixes dropbox sync issues on linux

# fix the permissions
sudo chown -R $USER ~/Dropbox

sudo chown -R $USER ~/.dropbox
sudo chmod -R u+rw ~/.dropbox
# remove any conflicting files from the file list above step 1
grep -v -e "conflicted copy" -e "Case Conflict" /tmp/dropbox_files-`date +%Y%m%d` > /tmp/dropbox_files-`date +%Y%m%d`.txt
# set the executable permissions back
for files in `echo /tmp/dropbox_files-\`date +%Y%m%d\`.txt` ; do chmod u+x "${files}" ; done
# remove any files that are in conflict
find ~/Dropbox -type f -name \*"conflicted copy"\* -exec rm -f "{}" \;
find ~/Dropbox -type f -name \*"Case Conflict"\* -exec rm -f "{}" \;
# remove temp files
rm -f /tmp/dropbox_files-`date +%Y%m%d`
rm -f /tmp/dropbox_files-`date +%Y%m%d`.txtAnyways, this script will fix the problems. Make sure you adjust the path if your linux install does not have dropbox at ~/Dropbox.
One of the easiest ways to set up a subversion server that is lightweight is to use an existing linux server with sufficient free space available to hold your repositories. This is much more lightweight because it really doesn’t require any additional software or services, outside of subversion which is likely already installed if you use the svn client; and ssh which is probably already installed and running.
I will give the steps I used for centos, but it will work with other linux distributions if you apply the correct package management steps (pacman, apt-get, yum, emerge, etc):
First, make sure we have subversion and openssh installed:
yum install subversion openssh-server
So, I use linux exclusively….for everything except my photography post-processing. I don’t care about the rants and raves people give me about gimp, my workflow has included photoshop since Photoshop v3.0 (like mid-1990′s), and its just too hard to switch…..so I keep one windows machine around just to do photoshop tasks.
Now that I have my fluxbox bliss on my 16GB Quad-core machine dual booting with the factory Windows 7….I thought it would be nice to be able to run windows 7 inside of Linux. In the past, I always did the “virtualbox from new installation”. Its kind of a pain in the ass and a huge waste of disk space.
Doing some quick research, I found several articles on booting the physically installed windows in virtualbox and after many trials and errors, I found a simple solution that works.
Here is how I set it up…..
I have set up many laptops and netbooks with linux and have always used either full-disk encryption or ~/ encrypted. Its really easy to do and ANY laptop/netbook/tablet/pad/whatever_next mobile device should be encrypted. I won’t get into the mechanics of why, just do it. The last article I wrote about this is no longer online (Maysville Linux Users Group, circa 2007) and it was much harder to accomplish back then, often requiring custom kernels to be compiled, etc. Backtrack has “nearly” everything it takes right on the live cd.
Prerequisites
I have been using cluster ssh on and off for some time now but I have never written about it. So first, let me tell you what my definition of it is……a huge time saver for multiple like tasks that need completed across many servers or systems.
As an example, lets say a critical update comes in and it affects 25 web servers, a lot of people will log into each web server, perform the update, log out, go to the next one, etc until completed. That’s a huge waste of time….assuming it takes 5 minutes to log in, run the update, log out, log into the next one….that is 25 x 5 or roughly 125 minutes, slightly more than 2 hours.
I am finally going to add this to an article, even though I have had this 1rst generation ipod touch since release day and have used it with Linux since day 1……
To use your ipod with fluxbox requires three packages.
sudo apt-get install gtkpod libimobiledevice-utils libimobiledevice1You then have to mount your ipod touch and since fluxbox doesn’t really have a way to do that….I made a script:
#!/bin/bash
#
# mount ipod touch script by ed wiget
sudo /usr/local/sbin/usbmuxd -v -u &
DETECTED="echo -e `ideviceinfo` | wc -l"
#echo -e "is it ok to continue with the mount command?"
#read answer
#if [ $answer == 'y' ]
if [ ${DETECTED} -ge 1 ];
then
echo "ipod detected...mounting"
ifuse /media/ipod
else
echo "ipod detection failed....exiting"
exit
fiAfter it is mounted, you can then run gtkpod and it should auto detect it. It will create a database of the song hashes.
During usage, if you receive an error with gtkpod during song export that says:
CRITICAL **: transfer_track_glist_between_itdbs: assertion `!new_tracks' failed
Segmentation faultRestart gtkpod, select the playlist you were exporting and on the export dialog box, uncheck “Check for duplicates”. Now exporting will work.
