[125003480050] |It doesn’t have the menus, toolbars and other accoutrements of a traditional web browser. [125003480060] |An SSB also offers tighter integration with the operating system and desktop than a typical web application running through a web browser. [125003480070] |Applications running in an SSB are therefore able to benefit from many of the advantages of the desktop and of the web at the same time. [125003480080] |Benefits [125003480090] |Separate process: Web apps can hog memory or processor cycles or even bring down the whole browser in extreme cases. [125003480100] |By running each app in its own process, we minimize the impact of any mishaps. [125003480110] |We can also benefit from operating system tools that less us view the memory/CPU consumption of a specific application. [125003480120] |Minimal user interface: A general-purpose browser UI is not necessary or appropriate for most web apps. [125003480130] |It is more efficient to provide a UI that is specific to the application. [125003480140] |This also cuts down on UI clutter (hence the term distraction-free browser). [125003480150] |Basic desktop integration: Support of desktop features can make using the app more natural and convenient for end users. [125003480160] |This includes the ability to create desktop shortcuts, to place the application icon in the tray or dock and to display pop-up notifications. [125003480170] |Customization: Apps can be run using a shared browser runtime and customized using client-side script (similar to Greasemonkey). [125003480180] |Custom stylesheets can be used to tweak the UI. [125003480190] |Available Prism Packages in Ubuntu 8.04 [125003480200] |prism-facebook prism-google-analytics prism-google-calendar prism-google-docs prism-google-groups prism-google-mail prism-google-reader prism-google-talk prism-twitter [125003480210] |Install Prism packages for google using the following command [125003480220] |sudo aptitude install prism-google-talk prism-google-mail prism-google-docs prism-facebook prism-google-analytics [125003480230] |You can install all the packages menctioned above.This will complete the prism packages installation.

[125003500030] |In fact my Network Manager is intermittently buggy, connecting sometimes and not others. [125003500040] |This guide benefits all users in case the GUI tools are not working, and is useful for testing a wireless connection during initial installation of wireless drivers since it provides for good debugging output. [125003500050] |Unencrypted/ WEP / WPA connections will be covered in this guide [125003500060] |Pre-requisites [125003500070] |1. Properly installed network driver -- This guide can be used to troubleshoot driver installation to see if it is properly functioning [125003500080] |2. The ESSID of your router must be broadcasted and not hidden [125003500090] |3. Knowlege of your wireless cards driver (please see Prerequisite #4 to determine driver). [125003500100] |Those using the r8187/r818x driver please see the end of the guide [125003500110] |4. Knowledge of your wireless card’s Interface Name - The user must know the proper interface of the wireless connection (wlan0, eth1, rausb1, etc). [125003500120] |To discover this information, at command line type [125003500130] |lshw -C network [125003500140] |There may be multiple interfaces listed, however look under the section appropriate to your wireless device for the line labeled logical name.

I will refer to the interface name throughout the rest of this guide as [interface]. [125003500180] |For people first setting up their connection, please note that the above also lists the driver used for the network card. [125003500190] |In the example above, the driver used is ndiswrapper. [125003500200] |If your network device comes back UNCLAIMED or there is no driver listed, then you have not correctly installed the driver for your device. [125003500210] |You must review the procedures for installation of your wireless driver.

[125003630030] |It is able to crack password protected zip files with brute force or dictionary based attacks, optionally testing with unzip its results. [125003630040] |Install fcrackzip in Ubuntu [125003630050] |sudo aptitude install fcrackzip [125003630060] |This will complete the installation. [125003630070] |Fcrack Syntax [125003630080] |fcrackzip [-bDBchVvplum2] [--brute-force] [--dictionary] [--benchmark] [--charset characterset] [--help] [--validate] [--verbose] [--init-password string/path] [--length min-max] [--use-unzip] [--method name] [--modulo r/m] file. [125003630090] |fcrack Options [125003630100] |-h, --help Prints the version number and (hopefully) some helpful insights. -v, --verbose Each -v makes the program more verbose. -b, --brute-force Select brute force mode. [125003630110] |This tries all possible combinations of the letters you specify. -D, --dictionary Select dictionary mode. [125003630120] |In this mode, fcrackzip will read passwords from a file, which must contain one password per line and should be alphabetically sorted (e.g. using (1)). -c, --charset characterset-specification Select the characters to use in brute-force cracking. [125003630130] |Must be one of [125003630140] |a include all lowercase characters [a-z] A include all uppercase characters [A-Z] 1 include the digits [0-9] ! include [!:$% /()=?[]+*~#] : the following characters upto the end of the spe- cification string are included in the character set. [125003630150] |This way you can include any character except binary null (at least under unix). [125003630160] |For example, a1:$% selects lowercase characters, digits and the dollar and percent signs. [125003630170] |-p, --init-password string Set initial (starting) password for brute-force searching to string, or use the file with the name string to supply passwords for dictionary searching. -l, --length min[-max] Use an initial password of length min, and check all passwords upto passwords of length max (including). [125003630180] |You can omit the max parameter. -u, --use-unzip Try to decompress the first file by calling unzip with the guessed password. [125003630190] |This weeds out false positives when not enough files have been given. -m, --method name Use method number “name” instead of the default cracking method. [125003630200] |The switch --help will print a list of available methods. [125003630210] |Use --benchmark to see which method does perform best on your machine. [125003630220] |The name can also be the number of the method to use. -2, --modulo r/m Calculate only r/m of the password. [125003630230] |Not yet supported. -B, --benchmark Make a small benchmark, the output is nearly meaningless. -V, --validate Make some basic checks wether the cracker works. [125003630240] |fcrackzip Examples [125003630250] |fcrackzip -c a -p aaaaaa sample.zip [125003630260] |checks the encrypted files in sample.zip for all lowercase 6 character passwords (aaaaaa …abaaba …ghfgrg …zzzzzz).

[125003710040] |What is tdbsam ? [125003710050] |Samba can store user and machine account data in a “TDB” (trivial database). [125003710060] |Using this backend does not require any additional configuration. [125003710070] |This backend is recommended for new installations that do not require LDAP. [125003710080] |As a general guide, the Samba Team does not recommend using the tdbsam backend for sites that have 250 or more users. [125003710090] |Additionally, tdbsam is not capable of scaling for use in sites that require PDB/BDC implementations that require replication of the account database. [125003710100] |Clearly, for reason of scalability, the use of ldapsam should be encouraged. [125003710110] |The recommendation of a 250-user limit is purely based on the notion that this would generally involve a site that has routed networks, possibly spread across more than one physical location. [125003710120] |The Samba Team has not at this time established the performance-based scalability limits of the tdbsam architecture. [125003710130] |There are sites that have thousands of users and yet require only one server. [125003710140] |One site recently reported having 4,500 user accounts on one UNIX system and reported excellent performance with the tdbsam passdb backend. [125003710150] |The limitation of where the tdbsam passdb backend can be used is not one pertaining to a limitation in the TDB storage system, it is based only on the need for a reliable distribution mechanism for the SambaSAMAccount backend. [125003710160] |The high growth rates projected are a good reason to use the tdbsam passdb backend. [125003710170] |The use of smbpasswd for the backend may result in performance problems. [125003710180] |The tdbsam passdb backend offers features that are not available with the older, flat ASCII-based smbpasswd database. [125003710190] |Install Samba Server in Ubuntu [125003710200] |Use the following command to install samba packages [125003710210] |sudo aptitude install libcupsys2 samba samba-common [125003710220] |This will complete the sama installation. [125003710230] |Configuring Samba in Ubuntu [125003710240] |First you need to Edit the smb.conf file using the following command [125003710250] |sudo vi /etc/samba/smb.conf [125003710260] |In the global section, remove the “;” at the front of the line security = user so it looks like this [125003710270] |security = user [125003710280] |to enable Linux system users to log in to the Samba server.

[125003720030] |As the name implies, this is a very simple, concise and easy to use backup application that uses the renowned and proven dar (Disk ARchive) to do the actual archiving. [125003720040] |Emphasis has been on providing true and reliable progress indication throughout all operations, as well as the ability to cancel any operation at any given point. [125003720050] |HUBackup mainly concerns with backing up your home folder data, allowing you to restore it in case of data loss.
