memperbaiki unable to lock the list directory" di Ubuntu

Pertama-tama ingin nyoba nginstall aplikasi di linux menggunakan perintah :

apt-get install


Ternyata saat saya coba malah muncul :
E: Couldn't find package


Tanpa basa-basi langsung meluncur ke Mbah Google kenapa ini bisa terjadi. Setelah muter-muter jalan yang dikasih ama Mbah akhirnya nemu, katanya harus di update dulu menggunakan perintah
apt-get update


saya juga tidak mengetahui untuk meng-update apa perintah itu , karena saya masih newbie di linux alias baru pakai linux kemaren-kemaren.
Setelah dicoba perintah update diatas eh masalah baru muncul :
E: Unable to lock the list directory


tanpa basa - basi untuk kedua kalinya langsung aja nanya lagi ke Mbah Google, akhirnya dapet perintah :
fuser -vki /var/lib/apt/lists/lock


Ternyata masalah ini karena ada apt-get yang dulu saya pernah jalankan namun saya cancel di tengah jalan. Jadi untuk mengatasinya bisa juga dengan perintah :


apt-get autoremove

Setelah meng-eksekusi perintah di atas akhirnya perintah apt-get update dan apt-get install sudah berjalan dengan lancar lagi dan tentunya untuk meng-update harus ada koneksi internet

How apt-fast

Matt Parnell of a geek who is well known, makes the syntax for the install process from the server to be faster, view of the increasing number of users in Indonesia, which has a low bandwidth, this method may be very useful.

But to be able to use it would be maximal if mated with axel download accelerator, how to just type the command:

code:
$sudo apt-get install axel

okay immediately wrote .. how do I install it? only 3 lines of command ...

$sudo add-apt-repository ppa:tldm217/tahutek.net $sudo apt-get update $sudo apt-get install apt-fast

The above commands can be used to install like (apt-fast update, apt-fast upgrades, apt-fast dist-upgrade, apt-fast-install), you try to update it ...

Instalation Ubuntu or Linux for Flashdisk

In this tutorial I want to explain a tutorial on how to install Linux using a flash. This method is claimed to be easier and faster than if we install Linux using a CD or DVD media. Almost all kinds of Linux distributions also support the installation using the flash.
Before that you need a minimum of 1GB of flash size. You also need the UNetbootin for Linux iso extract files into flash.
In addition, your PC or laptop must support booting from flash.

To download the UNetbootin you can click here. UNetbootin is available for Windows and Linux.

Various Linux distributions you can download the iso file it here.

Once everything is prepared, you can begin to install Linux using the flash.

Open the UNetbootin application you have downloaded.

Select diskimage.

Then search for Linux iso file that you downloaded earlier.



In the Type field select the USB Drive, in column Drive select the drive letter you want to install flash.

The installation will last for approximately 10 minutes, depending on the speed of transfer of your flash.
After clicking Reboot to start installing Linux.



When the computer restarts do not forget the BIOS settings for your laptop or PC can boot from flash. Usually by pressing F1, F2, F12, ESC, or backspace.

Port Scanner NMAP

Actually this tutorial long time ago I made .. tp klo does not hurt my posts in my blog, who knows could be useful for teman2 in need.

www.insecure.org
~ ~ ~ ~ Fydor

at this time I will explain the basis and concept of the use of nmap (port scanner) to find out how many are open port2 on the target. If there are no errors kesalahan2 writing or description, please in the correction ya .. because I am also still in the learning stage. for teman2 who already understand yes please add more of his articles, can let our deeper understanding in the use of nmap.

[-1. Is nmap it?
nmap port scanner is a very famous in the world of hacking. and many are used to audit a system, where to find open ports allowing those ports can be exploited by the intruder. msh many more besides NMAP port scanner in the Internet world, such as: superscan, THC, BluesPortTool, etc..

[-2. Explanation
nmap in the latest version now already has a feature that is very good at all, can even be said complete. This is very helpful at all when we start scanning or start a "peek" open port on the target computer. NMAP has a lot in terms of sanning techniques, such as: UDP, TCP Connect (), TCP SYN (half open), ftp proxy (bounce attack), ICMP (ping sweep), FIN, ACK sweep, Xmas Tree, Null scans, etc is .. NMAP also has the advantage to know what OS is used by the target .. Mmm .. Cool it! that not less mantepnya, in the latest version can spoof our IP and MAC. Begh ... Mantep Coy! This is useful for IP and MAC we can not know (anonymity network).
In practice I use nmap on windows, but in windows there are some functions that can not be executed but can be run on Linux: (. I also use ZA firewall (to view the log by an intruder), and sometimes I turn off the firewall (to view ports which benar2 open on my computer). because if we use a firewall, there are special port2 that he block and the lid is logical by the firewall.
"Woi!, Game tutorials dong .. even ngebacot again!" Ok .. Ok ... wait, yes, a little more direct koq practice. hehehehe ...: D

[-3. Supported platforms NMAP
Linux, Microsoft Windows, FreeBSD, OpenBSD, Solaris, IRIX, Mac OS X, HP-UX, NetBSD, Sun OS,

[-4. Depedencies on penginstall NMAP
if we want nmap running on windows we have to require that his name WinPcap. Download and install on your computer. can be downloaded at the link below:
http://www.winpcap.org

Download nmap on the link below. the installation directory, it's up to you routed .. tp klo may be yes in "C: \ nmap" let the easy access to it through cmd. : D
http://www.insecure.org/nmap/nmap_download.html

Performance of nmap can be found on his website. Tp, When I try on Linux, nmap faster process than in windows. That's according to me seh .. there may be an opposite.

[-4. Basic Scanning
If you want to see help from nmapnya
C: \ nmap> nmap-h

Example 1: You want to know what ports are open from ports 1-65535 and the OS is used by the target.
C: \ nmap> nmap-v-sS-p1-65 535-O 192.168.1.2

mean:
-V = verbose
-SS = stealth scan
-P = port scans
-O = OS detection
192.168.1.2 = target

Well, already you can see it port2 are open and what OS is running the target .. O yes, to run-sS (stealth scanning) you must have permissions as an admin. Um .. Gaining want that computer? Difficult Boy ..! Hehe .. Advanced ah ..

Example 2: The above his cuman only port and its service information .. now we will see the service and the version of the open port2. keep your eyes with me!

Well, now saw versionnya. : D

example 3:
When we do the scanning, we recorded real IP in the firewall log or if you use snort snort. Nah, klo dah caught .. Game Over dech ... dah dong is not fun anymore .. stay waiting in the target samperin aja ama. : D
Now as never before is how we maintain the anonymity of our footprinting nmap IP or during scanning. The concept we can do decoy or deception of a source (check me if i wrong). Oh no, kyanya confused neh. we immediately practice dech .. Here we use the IDS. Oh yeah, our computer with IP 192.168.1.1 and 192.168.1.2 target
C: \ nmap> nmap-v-sV-p 22-O 192.168.1.2
when we do the scanning .. snort logs record like this:

Hehe .. Our IP is not listed .. "Said the attacker, U can not get me."

Alhamdulillah, finally arrived at the end of this tutorial .. Hopefully useful tutorial .. yes actually there's still plenty more to be clarified .. tp klo mostly lazy to read it again instead Ntar ..

Prozilla

This time I discussed about the download manager again, and this difference as a download manager JDownloader previous. Unlike JDownloader, prozilla is lighter because they do not GUI based, which means to run it must use the terminal. To download acceleration equal to the IDM in windows (with the same internet connection) it can support even prozilla resume downloading are in IDM.

Some of his fiture include:

1. Supports FTP and HTTP
2. Supports Resume Download
3. Multiple connections and configuration of connections
4. Support for FTP search and choose the fastest server automatically
5. Used restricted maximum bandwidth (bps / bytes per second)

Instalasinya cukup mudah, langkah-langkahnya sebagai berikut :
Buka terminal, lalu ketikkan ( copy paste perintah ini juga bisa )

$wget http://old-releases.ubuntu.com/ubuntu/pool/universe/p/prozilla/prozilla_1.3.7.4-1_i386.deb

next:

$sudo dpkg -i prozilla_1.3.7.4-1_i386.deb

Once completed installed we can arrange a place / file that is downloaded is in prozilla.conf

$sudo gedit /etc/prozilla.conf

Find the lowest writing (mainoutputdir), and content suitable location that you want an example. Do not forget to delet a # before mainoutputdir

mainoutputdir = /home/panji/downloads

Save and exit. Prozilla you're ready to use. Emmm how how?

Previously there are several options when you akanmendownload file:

-R: used for files that you download can diresume (depending on the download from where)
-K = 10: sample mean in addition to the downloaded file will be divided into 10 connections.
-Max-bps = 30 000: these options are used for bandwidth becomes 30KBps melimit

For example, suppose we will medownload a file

proz -r -k=4 http://www61.indowebster.com/70e4b074f3fcc96647f20ac60f3e01a4.rar


Good Luck ^_^..

TuxCut = NetCut in Linux

TuxCut, an application that can be used to cut off Internet access at hotspots, or a PC LAN workgroup from client to server or vice versa by using the ARP protocol. This program is used by network users are impish and want to take a quota of bandwidth for his own use. Tuxcut PyQt made of language, for more details can directly visit the official website at

http://bitbucket.org/a_atalla/tuxcut/src/

In the feature bundle Tuxcut been created to protect us for our internet connection can not be dicut or in pieces by other users. In addition, there are features for scanning and MAC MAC changer, too. In contrast to Netcut, so we are protected from mischievous users who use Netcut, we have to install the program again the AntiNetcut (although netcut always more advanced than the anti netcut).

For how to uninstall it, here I use the Ubuntu Linux-based operating system.
1. Download TuxCut, because we want to install in kubuntu, we downloaded the debian package in

http://bitbucket.org/a_atalla/tuxcut/downloads/TuxCut-3.2_all.deb

2. Before installing TuxCut, we need to install arp-scan arp-tables and dsniff (requires Internet connection for kebih easily install it in the process)
a. Install with the command arp-scan

$ sudo apt-get arp-scan

b. Install dsniff with the command

$ sudo apt-get install dsniff

c. Install arptables, download the latest version of arptables

http://sourceforge.net/projects/ebtables/files/arptables/
The command:

tar zxf arptables-v0.0.3-3.tar.gz cd arptables-v0.0.3-3 make && make install

3.Install TuxCut with the command

$ sudo dpkg -i TuxCut-3.2_all.deb

* /If there are errors because the libraries are still lacking, they can apply the following command: apt-get install-f*/

initial appearance on tuxcut:


penggunaanya hampir sama dengan netcut pada sistem operasi windows
Good Luck ^_^...

Anti-Firesheep Trick Protects Linux Users

The Firesheep plug-in for Firefox has done an admirable job of illustrating the insecurity of public Wi-Fi, just as its creators intended. Now that it's out there in the wild, however, the question for users is how to protect their sensitive information.

On the Windows side, pretty much all we've seen so far have been tools that simply alert you when Firesheep is being used on the network you're connected to. Unfortunately, they don't go beyond that to actually protect your data.
For Linux users, however, the situation is better. A free new solution from security firm Sophos lets users of the open source operating system "browse over unencrypted Wi-Fi access points with no more risk than you'd browse at home," according to its blog post from earlier today.
It takes only 60 seconds to set up, even for users on the road, and it works even if you're already working over unencrypted Wi-Fi, the company says.
Remote Browsing
Sophos's solution centers on a 120-line Python http proxy hosted at a URL in Japan. Users begin by visiting that URL and then cutting and pasting the proxy into an editor and saving it, resulting in a 4500-byte file.
Next, users secure-copy that file onto the shell server on their home network so they can run the proxy remotely, away from the insecure Wi-Fi network. They then start that proxy with an encrypted SSH tunnel so they can send and receive the http content securely from that insecure Wi-Fi network to their home network, where the browsing requests will actually take place.
Users then simply tell their browser that they're going to surf over that SSH tunnel to the remote proxy, effectively allowing them to browse the Web from the airport or wherever via the security of their home network.
A YouTube video demonstrates the process involved, including the specific commands and Firefox settings.
The Linux Advantage
Linux users already enjoy many widely acknowledged security advantages over their Windows counterparts, so it's nice to see one more such benefit in the world of Wi-Fi.
As for Windows users? They'd probably do well to consider Wi-Fi alternatives such as tethering or MiFi, at least when dealing with sensitive data.
