former QueSO home page <URL:http://www.apostols.org/projectz/queso/>: How we can determine the remote OS using simple TCP packets? Well, it's easy, they're packets that don't make any sense, so the RFCs don't clearly state what to answer in these kind of situations. Facing this ambiguous, each TCP/IP stack takes a different approach to the problem, and this way, we get a different response. In some cases (like Linux, to name one) some programming mistakes make the OS detectable. QueSO sends: 0 SYN * THIS IS VALID, used to verify LISTEN 1 SYN+ACK 2 FIN 3 FIN+ACK 4 SYN+FIN 5 PSH 6 SYN+XXX+YYY * XXX & YYY are unused TCP flags All packets have a random seq_num and a 0x0 ack_num.

ubh - the Usenet Binary Harvester - is a GPL'ed Perl console application which automatically discovers, downloads, and decodes single-part and multi-part Usenet binaries. Automatically assembles multi-part binaries. Provides searching via Perl regular expression syntax. Also provides a pre-selection capability whereby the user can interactively choose which binaries to download. Uses a standard .newsrc file to control which groups and articles to process. Runs anywhere Perl runs. Tested under Unix-based Perl, Active Perl on Win32 platforms, and Mac OS X. Requires Net::NNTP and News::Newsrc (which itself requires Set::IntSpan), MIME::Parser, MIME::Base64, IO::Stringy, and MailTools (distribution).

If PDF is electronic paper, then pdftk is an electronic staple-remover, hole-punch, binder, secret-decoder-ring, and X-Ray-glasses. Pdftk is a simple tool for doing everyday things with PDF documents. Keep one in the top drawer of your desktop and use it to: Merge PDF Documents Split PDF Pages into a New Document Decrypt Input as Necessary (Password Required) Encrypt Output as Desired Burst a PDF Document into Single Pages Report on PDF Metrics, including Metadata and Bookmarks Uncompress and Re-Compress Page Streams Repair Corrupted PDF (Where Possible) Pdftk is also an example of how to use a library of Java classes in a stand-alone C++ program. Specifically, it demonstrates how GCJ and CNI allow C++ code to use iText's (itext-paulo) Java classes.

Orthanc aims at providing a simple, yet powerful standalone DICOM server. It is designed to improve the DICOM flows in hospitals and to support research about the automated analysis of medical images. Orthanc can turn any computer running Windows, Linux, FreeBSD or OS X into a DICOM store (in other words, a mini-PACS system). Its architecture is lightweight and standalone, meaning that no complex database administration is required, nor the installation of third-party dependencies. What makes Orthanc unique is the fact that it provides a RESTful API. Thanks to this major feature, it is possible to drive Orthanc from any computer language. The DICOM tags of the stored medical images can be downloaded in the JSON file format. Furthermore, standard PNG images can be generated on-the-fly from the DICOM instances by Orthanc. Orthanc lets its users focus on the content of the DICOM files, hiding the complexity of the DICOM format and of the DICOM protocol.

HDF5 is a completely new Hierarchical Data Format product consisting of a data format specification and a supporting library implementation. HDF5 is designed to address some of the limitations of the older HDF product and to address current and anticipated requirements of modern systems and applications. HDF5 includes the following improvements: - A new file format designed to address some of the deficiencies of HDF4.x, particularly the need to store larger files and more objects per file. - A simpler, more comprehensive data model that includes only two basic structures: a multidimensional array of record structures, and a grouping structure. - A simpler, better-engineered library and API, with improved support for parallel I/O, threads, and other requirements imposed by modern systems and applications.

Kst is a fast real-time large-dataset viewing and plotting tool with basic data analysis functionality. Kst contains many powerful built-in features and is expandable with plugins and extensions. Features of Kst include: - Robust plotting of live "streaming" data. - Powerful keyboard and mouse plot manipulation. - Large selection of built-in plotting and data manipulation functions, such as histograms, equations, and power spectra. - Color mapping and contour mapping capabilities for three-dimensional data, as well as matrix and image support. - Monitoring of events and notifications support. - Built-in filtering and curve fitting capabilities. - Convenient command-line interface. - Powerful graphical user interface. - Support for several popular data formats. - Extended annotation objects similar to vector graphics applications. This port provide Kst 2, which is based on Qt4. It still lacks scripting support and backward compatibility with Kst 1.x series (you can't open kst-1 files in Kst 2).

TinyCA is a simple graphical userinterface written in Perl/Tk to manage a small CA (Certification Authority). Currently TinyCA supports the following features: * unlimited number of CAs * support for creating and managing SubCAs * Creation and Revocation of x509 - S/MIME certificates * PKCS#10 Requests can be imported and signed * RSA and DSA keys can be generated and used * Servercertificates o Certificates can be exported as: PEM, DER, TXT and PKCS#12 o Certificates may be used with e.g. Apache, Postfix, OpenLDAP, Cyrus and FreeS/WAN * Clientcertificates o Certificates can be exported as: PEM, DER, TXT and PKCS#12 o Certificates may be used with e.g. Netscape, Konqueror, Opera, Internet Explorer, Outlook (Express) and FreeS/WAN * Certificate Revocation List o CRLs can be exported as: PEM, DER and TXT

viewglob is an utility designed to complement the Unix shell in graphical environments. It has two parts: 1. A tool that sits as a layer between the shell and X terminal, keeping track of the user's current directory and command line. 2. A graphical display which shows the layouts of directories referenced on the command line (including pwd). The display reveals the results of file globs and expansions as they are typed (hence the name), highlighting selected files and potential name completions. It can also be used as a surrogate terminal, where keystrokes typed in the display are passed to the shell. Files and directories can be double-clicked to insert their names and/or paths into the terminal.

clone is a file tree cloning tool which runs 3 threads - a scheduler (main), a reader, and a writer thread. Reading and writing occurs in parallel. While this is most beneficial for copying data from one physical disk to another, clone is also very well suited for cloning a file tree to any place on the same disk. Cloning includes the whole directory hierarchy, i.e. sub-directories, files, hard links, symbolic links, attributes (modes, flags, times), extended attributes and access control lists. clone is useful for cloning (thus backing-up) live file systems, and it can also be used in incremental and synchronization mode. clone works on FreeBSD and Mac OS X. clone is very fast, for example, cloning a whole UFS2 file hierarchy on FreeBSD 9.1 of in total 2.3 TBytes of data from one hard disk to another took 7.5 h, so the average transfer rate for all kind of files (very small up to very big ones) was about 89 MByte/s.

powerman is free Unix/Linux software that controls (remotely and in parallel) switched power distribution units. It was designed for remote power control of Linux systems in a data center or cluster environment, but has been used in other environments such as embedded management appliances, home automation, and high availability service management. powerman can be extended to support new devices using an expect-like scripting language. It communicates with devices natively using telnet, raw socket, and serial protocols. It also can drive virtual power control devices via a coprocess interface. The coprocess mechanism has been used to extend powerman to communicate with devices using other protocols such as SNMP, IPMI, Insteon, X-10, and VXI-11. powerman can control equipment connected using any combination of the above methods and provide unified naming for the equipment and parallel execution of control actions.
