ABSTRACT THINC: A Virtual and Remote Display Architecture for Desktop Computing and Mobile Devices Ricardo A. Baratto THINC is a new virtual and remote display architecture for desktop computing. It has been designed to address the limitations and performance shortcomings of existing remote display technology, and to provide a building block around which novel desktop architectures can be built. THINC is architected around the notion of a virtual display device driver, a software-only component that behaves like a traditional device driver, but instead of managing specific hardware, enables desktop input and output to be intercepted, manipulated, and redirected at will. On top of this architecture, THINC introduces a simple, low-level, device-independent representation of display changes, and a number of novel optimizations and techniques to perform efficient interception and redirection of display output. This dissertation presents the design and implementation of THINC. It also intro- duces a number of novel systems which build upon THINC's architecture to provide new and improved desktop computing services. The contributions of this dissertation are as follows: • A high performance remote display system for LAN and WAN environments.

Palvelimilla suoritettavat ohjelmat hyödyntävät laitteistoresursseja tehokkaasti ja työasemina voidaan käyttää iäkkäitäkin tietokoneita. Tässä opinnäytetyössä tutkittiin mahdollisuutta muuttaa tehdasympäristössä Windows XP -työasemat Linux-pohjaisiksi MS Remote Desktop Services -päätteiksi. Muutoksen tuli olla käyttäjille huomaamaton. Tärkeimpänä tavoitteena oli vähentää työasemien ylläpitoon kuluvaa aikaa. Tätä varten päätejärjestelmässä oli oltava mahdollisuus hallita työasemien asetuksia keskitetysti. Eri toteutustapoja arvioitiin näitä vaatimuksia vasten ja rakennettiin vaatimukset täyttävä päätejärjestelmä. Kutakin päätejärjestelmää testattiin ensin virtuaalisesti. Näin pyrittiin löytämään ja ratkaisemaan mahdolliset ongelmat ennen varsinaista koekäyttöä. Tehtaassa tapahtunutta koekäyttöä varten perustettiin tarpeelliset palvelimet ja otettiin päätejärjestelmät käyttöön yhdessä tai useammassa työasemassa. Saatujen kokemusten perusteella arvioitiin järjestelmien käyttökelpoisuutta. Työn lopputuloksena syntyi ohutpääteratkaisu,

PySAL is open source under the BSD License. Contents 1 pysal Documentation, Release 1.14.3 2 Contents CHAPTER 1 User Guide 1.1 Introduction Contents • Introduction – History – Scope – Research Papers and Presentations 1.1.1 History PySAL grew out of a collaborative effort between Luc Anselin’s group previously located at the University of Illinois, Champaign-Urbana, and Serge Rey who was at San Diego State University. It was born out of a recognition that the respective projects at the two institutions, PySpace (now GeoDaSpace) and STARS - Space Time Analysis of Regional Systems, could benefit from a shared analytical core, since this would limit code duplication and free up additional developer time to focus on enhancements of the respective applications. This recognition also came at a time when Python was starting to make major inroads in geographic information systems as represented by projects such as the Python Cartographic Library, Shapely and ESRI’s adoption of Python as a scripting language, among others. At the same time there was a dearth of Python modules for spatial statistics, spatial econometrics, location modeling and other areas of spatial analysis, and the role for PySAL was then expanded beyond its support of STARS and GeoDaSpace to provide a library of core spatial analytical functions that could support the next generation of spatial analysis applications.

PRODUCTS COMPANY PARTNERS CUSTOMERS SUPPORT Home > Blog > SysKit Monitor > CredSSP required by server – Solutions CredSSP required by server – Solutions Published: May 16, 2017 Published in: SysKit Monitor Author: Silvio Rahle Failed to connect, CredSSP required by server is an error line returned when trying to connect remotely to a Windows machine using RDP version 6 or newer with the Rdesktop client. It represents a frequent problem for Windows and Linux administrators alike. Rdesktop client is UNIX based client software for Microsoft’s Remote Desktop Protocol. It is commonly used on ReactOS and Linux installations to connect to Windows machines running Remote Desktop Services, which often leads to the CredSSP required by server error. Why does it happen? All Windows clients have a credential cache used for authentication against services in a network called NTLM or Windows NT LAN Manager. RDP supports SSO (single sign-on) authentication enabling a user to log in with a single ID and password to gain access to a connected system. However, Linux clients do not support this type of authentication and they require that credentials are provided, either via a Rdesktop command line or via a login window when initiating the remote session.

    Courtesy of SAMAG, 11-2005 (http://www.samag.ru) Anton Borisov Тонкий клиент - шаг к “мэйнфреймам”? Когда-то терминалы подключались к мощным серверам и обработка информации происходила на мэйнфреймах. Затем появились достаточно мощные ПЭВМ и информация стала обрабатываться на рабочих местах. Похоже история любит повторяться, но сегодня уже в зеркальном отражении - становится опять экономически выгодно использовать “мэйнфреймы” с подключением легких терминалов - тонких клиентов. Как показывает практика, чем сложнее становится система, тем больше усилий требуется на поддержание ее в рабочем состоянии. В то же время, становится очевидной специализация тех или иных бизнес-процессов. Можно уже четко определить, какие конкретно ресурсы требуются определенным пользователям для решения их бизнес-задач. Исходя из указанных предпосылок данным пользователям следует выделить необходимый конкретно им инструментарий, но не более того. Кроме этого, установку (а в дальнейшем и обновление) пакетов прикладных программ, хранение электронной документации также рациональнее вести в одином месте – на производительном терминальном сервере. Таким образом, проведя анализ потоков данных и выяснив структуру документооборота, предприятие может попробовать преобразовать структуру рабочих мест. Из названия следует, что ориентир сделан на создание тонких клиентов, т.е. создание ПЭВМ, которые отображают выполнение програмного обеспечения на серверной стороне, при этом, будучи клиентской частью, могут быть совершенно облегченными. Под облегченностью понимается как использование

  • Установка И Настройка Rtorrent+Rutorrent+Nginx+Php-Fpm В Arch Linux 1 / 9
    УСТАНОВКА И НАСТРОЙКА RTORRENT+RUTORRENT+NGINX+PHP-FPM В ARCH LINUX 1 / 9 Установка и настройка rtorrent+rutorrent+nginx+php-fpm в Arch Linux Предыстория Для работы с торрентами я достаточно долго использовал ktorrent. Сей клиент мои потребности в удобном управлении закачками удовлетворял полностью, пока я не заметил, что на популярных торрентах загрузка процессора доходила до 50% (а с uTP — ещё больше), а потребление памяти в и без того жирном KDE стало неприятно бросаться в глаза. Было решено сменить KDE на xfce (это отдельная история), а программу для торрентов подобрать с хорошим функционалом и удобным управлением. Перепробовав transmission, deluge и rtorrent, я остановлися на последнем. О том, как настроить rtorrent+rutorrent+nginx+php-fpm, и будет под катом. Почему так? Сразу хочу ответить, почему выбраны именно означенные инструменты. Arch Linux. Об этом дистрибутиве можно говорить достаточно долго, мне нравится его организация и философия в целом, и я могу его использовать для себя с максимальной эффективностью. Кому интересно более детально прочитать о нём, смотрите сюда и сюда. nginx.

Чтобы установить веб-часть связки, выполняем команду: sudo pacman -S nginx php-fpm rtorrent и librtorrent я рекомендую устанавливать с AUR'а, там есть замечательный PKGBUILD под названием rtorrent-color, делающий скучный консольный интерфейс более приятным (если будете им пользоваться), и libtorrent-extended, имеющий дополнительные патчи.

  • Master's Thesis
    MASTER'S THESIS Analysis of UDP-based Reliable Transport using Network Emulation Andreas Vernersson 2015 Master of Science in Engineering Technology Computer Science and Engineering Luleå University of Technology Department of Computer Science, Electrical and Space Engineering Abstract The TCP protocol is the foundation of the Internet of yesterday and today. In most cases it simply works and is both robust and versatile. However, in recent years there has been a renewed interest in building new reliable transport protocols based on UDP to handle certain problems and situations better, such as head-of-line blocking and IP address changes. The first part of the thesis starts with a study of a few existing reliable UDP-based transport protocols, SCTP which can also be used natively on IP, QUIC and uTP, to see what they can offer and how they work, in terms of features and underlying mechanisms. The second part consists of performance and congestion tests of QUIC and uTP imple- mentations. The emulation framework Mininet was used to perform these tests using controllable network properties. While easy to get started with, a number of issues were found in Mininet that had to be resolved to improve the accuracy of emulation. The tests of QUIC have shown performance improvements since a similar test in 2013 by Connectify, while new tests have identified specific areas that might require further analysis such as QUIC’s fairness to TCP and performance impact of delay jitter. The tests of two different uTP implementations have shown that they are very similar, but also a few differences such as slow-start growth and back-off handling.

  • Bittorrent's Been Around for a Whopping Ten Years, but It Continues to Evolve and Remains One of the Best File-Sharing Tools Available
    BitTorrent's been around for a whopping ten years, but it continues to evolve and remains one of the best file-sharing tools available. If you really want to make your downloads soar—and keep Big Brother out of your business—this guide's for you. We showed you how to get started sharing and downloading files with BitTorrent a few years ago, and most of that still applies, but if you're looking to up your BitTorrent skills, things have changed a lot since then. In fact, some of you may find BitTorrent a bit old school for your tastes. Sure, the ISPs are cracking down and throttling peer-to-peer users, and you have other great file-sharing alternatives like Usenet, but that doesn't mean BitTorrent doesn't still have a place in your routine. It's pretty easy to ward off prying eyes with today's BitTorrent clients, and while Usenet is certainly great, BitTorrent is still more widespread. As such, it tends to have a better selection on certain things, and is at the very least a good fallback method for when you don't find what you're looking for elsewhere. After all, there's no reason you have to be loyal to only one file-sharing protocol. This intermediate guide to BitTorrent is designed to help you do three things: jack up your speeds (without consuming your bandwidth) and keep unwanted snoopers from seeing what you're doing. We've divided them up into three sections: * Increase Your Speed and Privacy with a Few Easy Settings * Keep That Newfound Speed from Hijacking All Your Bandwidth * Really Hide Your Traffic with External Solutions For the purposes of this guide, we're focusing on two BitTorrent clients: uTorrent for Windows and Transmission for Mac OS X.
