I was getting CUPSD errors when trying to use my Laser Brother HL 2040 printer. But, you can install Brother HL-2040 by going to the brother website and downloading the linux drivers located here:
http://welcome.solutions.brother.com/bsc/public_s/id/linux/en/download_prn.html#HL-2040
I just installed the lpd driver using the command as follows:
$ sudo dpkg -i brhl2070nlpr-2.0.1-1.i386.deb
When printing now, just select local lpd and then select brother-HL2070 printer from the list (the drivers for both versions are same).

If this is the error you are getting then one of the solutions is to reset your root password on the MySQL database server.

$ pkill mysql
$ sudo mysqld --skip-grant-privileges
$ mysql

At this point you get the mysql command shell. You will need to update the root password and flush the table when you reset the password.

mysql> set UPDATE mysql.user SET Password=PASSWORD('YOUR_NEW_PASSWORD') WHERE User='root';
mysql> FLUSH PRIVILEGES;

Now that you’ve flushed your passwords, just restart your mysql daemon.

$ sudo pkill mysqld
$ sudo /etc/init.d/mysqld start
$ mysql -u root -p
Enter Password: YOUR_NEW_PASSWORD
mysql>

You should be all set now!

I’ve been a Batman fan since the time my father took me to watch the first Batman movie starring Michael Keaton. The latest addition to the Batman series is Christopher Nolan’s Batman Begins. The film is an excellent depiction of Batman and his rise as the caped crusader in Gotham City. The story is a prequel to the Batman movies which we have seen in the past.
The remaining cast is also well studded with some of the best actors of Hollywood like Michael Caine (Alfred) and Morgan Freeman. Katie Holmes also has done a good job of acting. But I still think that Michelle Pfeiffer is yet to be beaten in looks in the entire Batman series.
Overall, the movie is excellent with everything about Batman being explained and I think it’s a must watch for any Batman fan!

People tend to think that gone are the days when the “RPM Hell” used to exist. We have yum, aptitude and what not! If you install linux on a PS3, I’d like to bring you back to reality, especially like me when you have yellowdog 5.0 installed on a first gen PS3.
What is interesting is that all these package managers rely on repositories in /etc/yum.repos.d/*.
If you do not have the good repositories then you can kiss goodbye to installing the Cell Broadband Engine SDK provided by IBM. This SDK has the spu-gcc, spu-g++ which is the right set of compilers if you want to use the 1 master processor (Power Processor Element – PPE) and the other six SPE (Synergistic Processor Elements – SPEs) …think of these as slaves. You might wonder where’s the 7th of the cell processor, well, you cannot access it because it is used internally by the PS3 for virtualization.
So I got a yellow dog 5.0 iso image from here. I followed the instructions for installing it from here. I did this almost a year ago! Yes…I did actually keep it dead for a while! Then I installed gcc and compiled John the ripper! To my utter disappointment, there was no performance benefit!
Then Marc Bevand told me at Toorcon X that I needed spu-gcc to compile JTR on PS3 to get the benefits. So I got the cell sdk ISO from here. I then mounted the ISO.
mount -o loop cellsdk11.iso /mnt/disk
cd /mnt/disk
cd software
./cellsdk install
I got bunch of errors. It wanted me to install freeglut-devel and tk-8.4.*.
Thus began my journey of 10,000 steps to get the dependencies resolved and I burnt my fingers, keyboard, brains, etc….and although I realized that everyone in the US and the world had found hope…things were not looking bright for me! Until I bumped into this fantastic repository here. Trust me it took me about 8 hours of incessant installing and compiling (almost 120 odd different files) and scores of google searches to land me into this. I installed the glut, libx11, tk, tcl, libtcl, glut-devel, libstdc++, libstdc-so7, and many other packages that I cannot even recall now to get the cellsdk to work! And even though I did, I still couldnt get ./cellsdk install to work! After about 8 hours of effort and being so close to success just seemed evil. Then I realized that all the packages needed were related to the PPC64 simulator (libx11.ppc64, libtcl.ppc.64, etc.)…a quick look into the readme told me that I could neglect that using the –nosim directive to make it work.
Finally,
./cellsdk install –nosim
worked!!!!!
A small step for mankind but a giant step for me!

I have used Michal Zalewski’s Ratproxy on Google code. I like it a lot. But I also like to have it on Windows. But it seems that the makefile that comes with ratproxy is not really compatible with cygwin.
If you have the gcc, make, openssl, openssl-dev packages installed on cygwin, all you need to do is remove the -Wno-pointer flag from the CFLAGS entry from the Makefile.
So my Makefile’s CFLAGS line looks like:

CFLAGS  = -Wall -O3 -D_GNU_SOURCE

I also replaced $(CC) with gcc just because I felt like it. 🙂
Compile it with make command.
Do not forget to dos2unix the ratproxy-report.sh otherwise you will get some errors with ‘\r’ and some other random stuff when you run the report generator shell scripts.
Run ratproxy as :
c:\tools\ratproxy>ratproxy.exe -p 8000 -v c:\testdir -w ratlog -d example.com -extifscfjmXCk
Once you have the log to generate a nice looking pretty report:
bash$ ./ratproxy-report.sh ratlog >reportname.html

Update 06/20/2012:
If you get the error shown below:
ratproxy.c: In function `listen_loop':
ratproxy.c:1635:5: error: incompatible type for argument 2 of `waitpid'
/usr/include/sys/wait.h:43:7: note: expected `__wait_status_ptr_t' but argument
is of type `unsigned int *'
Makefile:30: recipe for target `ratproxy' failed
make: *** [ratproxy] Error 1

Do the following:
1. Go to line # 1635 and change the line to while (waitpid(-1,(int*)&x,WNOHANG) > 0);
2. Goto the command line and type

make

You should be able to compile ratproxy.

I will be speaking in Prof. Sengupta’s class at John Jay College of Criminal Justice at the City University of New York on Oct 28, 2010.  The topic of discussion will where does Digital Forensics fit in the big picture of organizations.  The talk will introduce the students to a variety of topics including choosing a career as a digital forensics investigator, their duties as an investigator, being successful as an investigator, case studies and real-life problems faced by the computer forensic investigators.

Finally, the CSCI 599 course on Search Engines concluded. The presentation went off pretty well.
The worst part was that an effort of 5 straight days went down the drain trying to go through the Nutch code. I think the Nutch developer community needs to get a little more matured and help newbies like me else new people would not join the movement! Eventually, I had to make my own focused crawler, query interface web data crawled and query interface.
I also got my CSCi558L scores which were ok…94,99,100 so things look ok so far but now the main effort is just starting off to get the Worm fingerprinting with ITrace going. Let’s hope things turn off well.
