Why the Internet Lives on a Few White Lies
In computer on June 30, 2009 at 16:01The addressing terminology that we now take more or less for granted is a
relic of the early 1990s. At the time, commercialization of the Internet had
just started, and somebody started calculating the number of computers that
would connect to the Internet if commercialization continued. The numbers
were staggering.
Packet Filter
In computer on June 30, 2009 at 15:57You have come here because you have
heard about the networking product called
PF, and you are most likely reading this post
because you want to learn what it’s all about. It’s
probably useful to start by spending a few moments
looking at the project’s history in order to put things
in their proper context.
Detecting and Protecting
In computer on June 30, 2009 at 15:51Because attackers also use network scanning, you must detect when your organization is a target and protect against network scanning activity. Monitoring for port scans can be a tricky task. You must find the right balance between performance and security. For example, it would not be effective to monitor for SYN scanning by alerting on every SYN packet.
Evasion and Spoofing
In computer on June 30, 2009 at 15:49A secure network blocks scanning techniques and alerts when a scan is detected. Firewalls block scanning attempts or drop responses to request packets. Intrusion detection systems (IDS) monitor network and host activity and create alerts when traffi c matches predefined signatures. Most scanning techniques are easy to detect and will easily trigger IDS alarms. Attackers therefore use a variety of techniques to scan in stealth mode to evade
fi rewalls and IDSs, including the following:
Port and Service Scanning
In computer on June 30, 2009 at 15:47Once you have identifi ed an active host you can attempt to identify the ports and services running on that host by performing port scanning. When an attacker performs port scanning, it is often compared to a burglar checking for unlocked doors and windows on a house. Knowing the open ports and services helps attackers further investigate vulnerabilities that can be possible entry points into the system. Port scanning sends a request to solicit a reply from ports on a target computer. There are many different
types of port scanning techniques. Most of them can be loosely categorized as the following:
Delete An “undeletable(error)” Files in windows :P
In computer on June 25, 2009 at 11:38once a time, you got something error windows when you are copying, cut, or paste your file with file manager (windust explorer maybe…). thus, what we used to fix this? in this post, i’ve been write about things to do when it happened. let’s say the solution is deleting a file. but,if you delete manually, you’ve got error message or bad redundancy file. let’s check now!here is to do.

something you should know about security …
In computer on June 25, 2009 at 11:31You may not realize it, but your computer and your motorcycle have something in common: they both need regular maintenance. No, you don’t need to change your computer’s oil. But you should be updating your software, keeping your antivirus subscription up to date, and checking for spyware,etc. Read on to learn what you can do to help improve your computer’s security.

something you must know about internet
In computer on June 25, 2009 at 11:22Why do I want to talk about InterNet? Well, because it is a prime
example of a TCP/IP network, better known as a WAN (Wide-Area-Network).
Now, mainly you will find BSD systems off of the Internet, or SunOS, for
they are the most common. They may not be when System V, Rel 4.0, Version
2.0 comes out. Anyway, these BSDs/SunOSs like to make it easy to jump
from one computer to another once you are logged in. What happens is
EACH system has a “yellow page password file”. Better known as yppasswd.
Hack and 0wn3d !
In computer on June 25, 2009 at 11:11The first step in hacking a UNIX is to get into the operating system
by finding a valid account/password. The object of hacking is usually to
get root (full privileges), so if you’re lucky enough to get in as root,
you need not read anymore of this hacking phile , and get into the
“Having Fun” Section. Hacking can also be just to get other’s accounts also.

this is unix means… :P
In computer on June 25, 2009 at 11:05This phile is geared as an UNIX tutorial at first, to let you get more
familiar with the operating system. UNIX is just an operating system, as
is MS-DOS, AppleDOS, AmigaDOS, and others. UNIX happens to be a multi-user-
multi-tasking system, thus bringing a need for security not found on MSDOS,
AppleDOS, etc. This phile will hopefully teach the beginners who do not have
a clue about how to use UNIX a good start, and may hopefully teach old pros
something they didn’t know before. This file deals with UNIX SYSTEM V and
its variants. When I talk about unix, its usually about SYSTEM V (rel 3.2).
Where Can I be found? I have no Idea. ![]()

bandwith is?
In computer on June 25, 2009 at 10:59BandWidth Explained
Most hosting companies offer a variety of bandwidth options in their plans. So exactly what is bandwidth as it relates to web hosting? Put simply, bandwidth is the amount of traffic that is allowed to occur between your web site and the rest of the internet. The amount of bandwidth a hosting company can provide is determined by their network connections, both internal to their data center and external to the public internet.
own a root … ?
In computer on June 25, 2009 at 10:50if you have try everything you knew, and got nothing…
well,
You’ve been at it for all night. Trying all the exploits you can think of. The system seems tight. The system looks tight.
The system *is* tight. You’ve tried everything. Default passwds, guessable passwds, NIS weaknesses, NFS holes, incorrect permissions, race conditions, SUID exploits, Sendmail bugs, and so on… Nothing. WAIT! What’s that!?!? A “#” ???? Finally! ![]()
After seeming endless toiling, you’ve managed to steal root.
Now what? How do you hold onto this precious super-user
privilege you have worked so hard to achieve….?

Protect your private wireless network from unauthorized use using PF (Packet Filter)
In computer on June 24, 2009 at 12:09The abundance of 802.11 wireless networks has raised an important question. How can you secure a wireless network so that only recognized systems can use it?
What Are Server Holes?
In computer on June 24, 2009 at 12:07A server vulnerability or hole is really just an application of previous ideas
touched upon in previous chapters, applied to applications that can be
reached on a remote machine. It may take the form of a remote buffer overflow.
It could be a poorly written cgi-bin script, a coding mistake in an authentication
daemon, or even a parsing error in reading incoming data. Server
vulnerabilities do not represent a class of vulnerabilities unto themselves, but
instead a means for conducting attacks discussed at length in prior chapters
of this review.

backup with rsync? or steal with rsync? :P~
In computer on June 24, 2009 at 12:04Think of rsync as simply a copy command that can copy between systems. It’s most like rcp in its syntax, but it’s also like the Windows copy command to some degree. However, it has gone beyond a simple copy program by adding features such as the following:
Copies links, devices, owners, groups, and permissions
Nmap for Newbie
In computer on June 24, 2009 at 12:00this is written for total newbies (Like myself) and talks about
the Hackers favourite target discovery tool “Nmap” coded by Fyodor.
Now If your like me, I like my programs to be quick, reliable and accurate
and Nmap is just that. Also if your a programmer (Like myself again) then
your get a kick out of viewing snippets of source code from these type of
programs (Open-Source) and Nmap again is just that ![]()

Distributed password cracking with Condor and John the Ripper
In computer on June 24, 2009 at 11:53Username/Password pair is commonly used method for user authentication. Password is a word that consists of letters, numbers and special characters. When registering to system, user chooses the password and system stores it in a safe manner. Systems must provide sound password storing mechanism in order to prevent unauthorized access to the system. Usually, systems use some hashing algorithm (e.g.MD5, SHA1) for storing passwords. On the other hand, it is the responsibility of users to choose reasonably complex passwords. Otherwise, the security of whole system can be compromised. Administrators usually define rules for creating passwords and insist on periodical password changing. In some cases, administrators choose to check quality of stored passwords. Password cracking is a process of recovering passwords from the safe system format. It consists of guessing the password, converting it to the stored format and comparing with stored value. There are several techniques for cracking passwords: guessing, dictionary attack and brute force
. Guessing approach uses information about users, such as birthday and login name to guess the password.
4 site a month !
In computer on June 22, 2009 at 12:28this month, i build 4 web site already. with the cpanel or else. and i building them with one work with CMS (cause i’m bored of coded !
) so, i’m install it and trying to secure it as i can. creating web with CMS is more fun to me because the GUI helps me to configure it most easily. i’m choose Joomla for my web. i know joomla just because my friends is the one of developers of joomla Content Management system. first i’m install of my server’s and voila! joomla was installed correctly and i just have to sets the templates and plugin installed. one think of my head is joomla have an huge developer and forum spread of the worlds!. my friend, be called w0rm_hack tells me many coders in Indonesian used the joomla’s work to re-coded their web without no credits to Joomla (its so bored! lazyness coder!and just copycat). 2 days later i know one site using the Joomla framework with re-coded version and sell sell it $250. woow…is very expensive to me. i earned $80-$120 with one site i’m coded. but this lil more more crazyness.
don’t let …
In me on June 22, 2009 at 12:25don’t let peoples give you a lots of problem
i’m the one person who let people to begin blame me. but, this day i willn’t let them to blame anymore. they always telling about me. why my life’s goes on. and how my family’s here to see me. if there is some serious problems bite me because of them, i give an apologize of them all. but, i’ll never to revenge them very much. i think if Alloh may be give them any chance,last chance
just another share … :P

first step
In computer on June 22, 2009 at 12:11hello, this is first time i’m post on my lanememory blog (and or may be the last?
). i’m confused if you really like my blog. this is just we made about this blog surely. and we only talks about: me, computer, and my LOVELY Reggy. Now, Reggy is my girlfriend, and someday she will marry me (we hope so). nothing of my blog post already available of answer, but if you really enjoy my post, you have mail me as possible. and this is my mail (dangerousboylearnhack@yahoo.com). so, i have to starting the daemon.
(be relax of my blog, and we will give it more!)
hello world! :P
