When trying to watch a short film clip or a short video, my computer stops showing the film, because the buffer cannot keep up . It may stop 6 or 7 times on a short clip.If I pause it long enough to let it...


your pc sounds really good... unfortunately, it sounds like your internet speed leaves a lot to be desired... or you need to upgrade your video card... if you have another computer and it does the same thing then its your internet speed... if another computer works great then try right clicking on video and adjusting buffer size to infinity and if that doesn't work then you need to upgrade video card...

Now, what do we do with this IP Address. Well first ping the IP Address to make sure that its alive. In otherwords online. Now at the bottom of this document ill include some links where you can obtain some key tools that may help on your journey through the electronic jungle. So we need to find places to get inside of the computer so we can start trying to find a way to "hack" the box. Port Scanners are used to identify the open ports on a machine thats running on a network, whether its a router, or a desktop computer, they will all have ports. Protocols use these ports to communicate with other services and resources on the network.

1) Blues Port Scanner - This program will scan the IP address that you chose and identify open ports that are on the target box.

Example 1:
Idlescan using Zombie (192.150.13.111:80); Class: Incremental
Interesting ports on 208.225.90.120:
(The 65522 ports scanned but not shown below are in state: closed)
Port State Service
21/tcp open ftp
25/tcp open smtp
80/tcp open http
111/tcp open sunrpc
135/tcp open loc-srv
443/tcp open https 1027/tcp open IIS
1030/tcp open iad1
2306/tcp open unknown
5631/tcp open pcanywheredata
7937/tcp open unknown
7938/tcp open unknown
36890/tcp open unknown


In example 1 now we see that there are a variety of ports open on this box. Take note of all the ports that you see listed before you. Most of them will be paired up with the type of protocol that uses that port (IE. 80-HTTP 25-SMTP Etc Etc...) Simply take all that information and paste it into notepad or the editor of your choice. This is the beginning of your targets record. So now we know what ports are open. These are all theoretical points of entry where we could wiggle into the computer system. But we all know its not that easy. Alright so we don't even know what type of software or what operating system that this system is running.

2) NMAP - Port Scanner - Has unique OS fingerprinting methods so when the program sees a certain series of ports open it uses its best judgement to guess what operating system its running. Generally correct with my experiences.

So we have to figure out what type of software this box is running if we are gonna start hacking the thing right? Many of you have used TELNET for your MUDS and MOOS and weird multiplayer text dungeons and many of you havent even heard of it before period. TELNET is used to open a remote connection to an IP Address through a Port. So what that means is we are accessing their computer from across the internet, all we need is their IP Address and a port number. With that record you are starting to compile, open a TELNET connection to the IP Address and enter one of the OPEN ports that you found on the target.
So say we typed 'TELNET -o xxx.xxx.xxx.xxx 25' This command will open up a connection through port 25 to the IP xxx.xxx.xxx.xxx. Now you may see some text at the very top of the screen. You may think, well what the hell, how is that little string of text going to help me. Well get that list you are starting to write, and copy the banners into your compilation of the information youve gathered on your target. Banners/Headers are what you get when you TELNET to the open ports. Heres an example of a banner from port 25.


220 jesus.gha.chartermi.net ESMTP Sendmail 8.12.8/8.12.8; Fri, 7 Oct 2005 01:22:29 -0400


Now this is a very important part in the enumeration process. You notice it says 'Sendmail 8.12.8/8.12.8' Well what do ya know, we now have discovered a version number. This is where we can start identifying the programs running on the machine. There are some instances in which companies will try and falsify their headers/banners so hackers are unable to find out what programs are truly installed. Now just copy all the banners from all the open ports *Some Ports May Have No Bannners* and organize them in the little record we have of the target. Now we have all the open ports, and a list of the programs running and their version numbers. This is some of the most sensitive information you can come across in the networking world. Other points of interest may be the DNS server, that contains lots of information and if you are able to manipulate it than you can pretend to hotmail, and steal a bunch of peoples email. Well now back to the task at handu. Apart from actual company secrets and secret configurations of the network hardware, you got some good juicy info. http://www.securityfocus.com is a very good resource for looking up software vulnerabilities. If you cant find any vulnerabilities there, search on google. There are many, many, many other sites that post vulnerabilities that their groups find and their affiliates.

At SecurityFocus you can search through vendor and whatnot to try and find your peice of software, or you can use the search box. When i searched SecurityFocus i found a paper on how Sendmail 8.12.8 had a buffer overflow. There was proof of concept code where they wrote the shellcode and everything, so if you ran the code with the right syntax, a command prompt would just spawn. You should notice a (#) on the line where your code is being typed. That pound symbol means that the command prompt window thats currently open was opened as root. The highest privilage on a UNIX/Linux Box. You have just successfully hacked a box. Now that you have a command shell in front of you, you can start doing whatever you want, delete everything if you want to be a ******* ****, however I dont recommend that. Maybe leave a text file saying how you did it and that they should patch their system.....whoever they are. And many times the best thing you can do is just lay in the shadows, dont let anyone know what you did. More often than not this is the path you are going to want to take to avoid unwanted visits by the authorities.

There are many types of exploits out there, some are Denial of Service exploits, where you shut down a box, or render an application/process unusable. Called denial of service simply because you are denying a service on someones box to everyone trying to access it. Buffer Overflow exploits are involved when a variable inside some code doesnt have any input validation. Each letter you enter in for the string variable will be 1 byte long. Now where the variables are located at when they are in use by a program is called the buffer. Now what do you think overflowing the buffer means. We overflow the buffer so we can get to a totally different memory address. Then people write whats called shellcode in hex. This shellcode is what returns that command prompt when you run the exploit. That wasnt the best description of a buffer overflow, however all you need to remember is that garbage data fills up the data registers so then the buffer overflows and allows for remote execution of almost every command available. There are many, many other types of attacks that cannot all be described here, like man-in-the-middle attacks where you spoof who you are. Performed correctly, the victim will enter http://www.bank.com and his connection will be redirected to your site where you can make a username and password box, make the site look legit. And your poor mark will enter their credentials into your site, when they think its really http://www.bank.com. You need to have a small script set up so it will automatiically display like an error or something once they try and log in with their credentials. This makes it seem like the site is down and the victim doenst give it a second thought and will simply try again later.

So as a summary of how to 0Wn a box when you only have an IP Address
Method Works On BOTH *Nix and Windoze

****You can do the same with domain names (IE google.com) than what you can with IP Addresses. Run a WHOIS Lookup or something along those lines. Or check up on InterNIC you should be able to resolve the domain name to an IP address.****

- Port Scan The Address And Record Open Ports
- Telnet To Open Ports To Identify Software Running On Ports

3) netcat - Network swiss army knife. Like TELNET only better and with a lot more functionality. Both can be used when you are trying to fingerprint software on open ports

- Record Banners And Take Note Of The Application Running and The Version Number
- Take A Gander Online At SecurityFocus.com or Eeye.com. If you cant find any vulnerabilities then search google.
- Make a copy of some Proof-Of-Concept code for the vulnerability.

*Read the documentation if there is any, for the proof-of-concept code you will be using for your exploit*

- Run The Exploit Against The Victim.
- Reap The Cheap-Sh0t Ownage

So guys...i hope you now know how to hack into a computer using a known IP Address. Once you get IP Address of the victim, you are able to access and hack the computer remotely as described in the post.\
i can & i will post more tricks
but first vote for me!

Adobe flashplayer makes buffering downstreaming videos on mediapl


buffering is a normal process..
it depends upon the size/content or connection speed..

In computing, a buffer is a region of memory used to temporarily hold data while it is being moved from one place to another. Typically, the data is stored in a buffer as it is retrieved from an input device (such as a keyboard) or just before it is sent to an output device (such as a printer). However, a buffer may be used when moving data between processes within a computer. This is comparable to buffers in telecommunication. Buffers can be implemented in either hardware or software, but the vast majority of buffers are implemented in software. Buffers are typically used when there is a difference between the rate at which data is received and the rate at which it can be processed, or in the case that these rates are variable

Buffer Override Detected


Try starting in safe mode and restore your PC to a date when it was working properly. Then increase the page files allotting it to all partitions, such that its now 3 times that what it was.These page files will be used from your HDD as if it were an extension of RAM. This should prevent any buffer over-run problems that you are facing now....sodeep
PS also clean your C drive if junk files, cookies & stored internet pages(History), defragment your HDD to improve performance.

This is the vendor driver/support page for your unit. The only driver they have is for 98SE which usually means that the card reader should be plug n play in Windows. You may want to try the card reader in another usb slot and put a memory card into it so Windows can better identify it. Post your results back here.

A buffer is a place to store data. You have a buffer overrun when to much data is sent to that place. It is used a lot by people who write virus programs and try to start a virus. It would be a good idea to check your entire drive for virus. The above link explains the same thing.

My windows xp when on yahoo watching my videos it is buffering and I can't see my videos can please help.


If its buffering the video is not playing yet. It is trying to store enough information so the video plays smooth. If the video stops buffering and it still does not show, try to update flash first then make sure you have the correct codecs installed.

Flash can be updated by going to www.adobe.com/support/flash/downloads.html
