  • Pembuatan Ftp Server Pada Server Redhat 4 Dengan Vsftpd
    Media Informatika Vol.13 No.1 (2014) PEMBUATAN FTP SERVER PADA SERVER REDHAT 4 DENGAN VSFTPD Hendy Djaja Siswaja E-mail : [email protected] Sekolah Tinggi Manajemen Informatika dan Komputer LIKMI Jl. Ir. H. Juanda 96 Bandung 40132 ABSTRAK FTP merupakan salah satu dari protokol pada jaringan komputer yang memiliki fungsi untuk memberi akses upload dan download file antar komputer yang terhubung dalam suatu jaringan komputer. FTP disukai karena mudah untuk dibuat dandapat dengan mudah untuk diakses dengan menggunakan web browser pada komputer. FTP paling banyak digunakan pada sistem operasi berbasis Linux, bahkan banyak distro-distro Linux yang menyediakan layanan FTP sebagai sarana bagi para user-nya untuk mendownload sistem operasi, update,aplikasi atau repositori lainnya. Kata kunci : ftp, VSFTPD, protokol, linux, jaringan komputer. 1. PENDAHULUAN Dalam setiap jaringan komputer, selalu muncul suatu kebutuhan dalam membagikan file-file komputer dari satu komputer ke komputer yang lain dan kebutuhan ini dapat dikatakan sebagai sesuatu hal yang bersifat primer (mendasar). Mengirimkan dan menerima file komputer mungkin merupakan suatu hal yang sederhana, bisa saja seseorang membagikan file komputer yang dimilikinya tanpa melalui jaringan komputer, misalnya melalui media perangkat penyimpanan sekunder seperti CD, DVD atau flashdisk. Namun cara seperti ini memiliki kekurangan terutama untuk file komputer yang sifatnya dinamis (sering mengalami perubahan) atau ketika pengirim dan penerima berada pada tempat yang berjauhan, misalnya berbeda kota maka pemindahan file dari satu komputer ke komputer yang lain dengan menggunakan media penyimpanan sekunder akan membutuhkan waktu cukup lama. Berangkat dari kebutuhan inilah maka para ahli jaringan komputer memikirkan suatu protokol yang memungkinkan satu komputer mengirimkan dan atau menerima data dari komputer yang lain melalui jaringan komputer sehingga kekurangan 44 45 Hendy Djaja Siswaja/ Pembuatan FTP Server pada Server Redhat 4 dengan VSFTPD dalam pembagian file melalui media penyimpanan sekunder dapat teratasi.

  • An Overview of Red Hat Linux
    Chapter 1 An Overview of Red Hat Linux In This Chapter • Introducing Red Hat Linux • What is Linux? • Linux’s roots in UNIX • Common Linux features • Primary advantages of Linux • What is Red Hat Linux? • Why choose Red Hat Linux? • The culture of free software Linux was a phenomenon waiting to happen. The computer industry suffered from a rift. In the 1980s and 1990s, people had to choose between inexpensive, market-driven PC operating systems from Microsoft and expensive, technology-driven operating systems such as UNIX. Free software was being created all over the world, but lacked a common platform to rally around. Linux has become that common platform. For several years, Red Hat Linux has been the most popular commercial distribution of Linux. With the latest versions of Red Hat Linux (reflected in the Fedora Core and Red Hat Enterprise Linux distributions), Red Hat, Inc. has taken steps to offer both free-flowing community versions and well-supported commercial versions of Red Hat Linux. NOTE: Because of significant overlap between Fedora Core and Red Hat Enterprise Linux, I use the term Red Hat Linux to refer to technology in both distributions. If software I describe is missing (primarily from Enterprise, which doesn't include many games and personal software), you can add the software later. Check your CDs, then check yum repositories described in Chapter 5 to find software RPMs. Introducing Red Hat Linux With the recent split between community (Fedora) and commercial (Red Hat Enterprise Linux) versions of Red Hat Linux, Red Hat has created a model that can suit the fast-paced changes in the open source world, while still meeting the demands for a well-supported 4 Part I: Getting Started in Red Hat Linux commercial Linux distribution.

  • Service-Fingerprinting Mittels Fuzzing (Mai 2009) 1
    Service-Fingerprinting mittels Fuzzing (Mai 2009) 1 Service-Fingerprinting mittels Fuzzing Michael Hanspach1 · Ralf Schumann1 Stefan Schemmer2 · Sebastian Vandersee2 1Fachhochschule der Wirtschaft FHDW, Bergisch Gladbach 2rt-solutions.de GmbH, Köln Zusammenfassung Für die Durchführung effektiver Penetrationstests ist die Identifizierung von Diensten (Services) und Applikationen auf den Zielsystemen, das sogenannte Service-Fingerprinting, von zentraler Bedeutung. Ziel dieses Beitrags ist es, mögliche Verbesserungspotentiale bestehender Fingerprinting-Tools zu beleuchten. Dies soll durch Einsatz von Mutation-Based Fuzzing zwecks einfacher und automatischer Erzeugung von Fingerprints erreicht werden. Durch Versenden der so präparierten Anfragen an bestimmte Dienste und Dienstversionen sollen subtile Unterschiede in den Antwortnachrichten erfasst werden, die Identifizierungs- und Unterscheidungsmerkmale bilden. Für den Nachweis der Praxistauglichkeit des Fuzzing-basierten Ansatzes und zum Vergleich mit bereits bestehenden Methoden und Tools wird eine Implementierung zum Fingerprinting von FTP- Servern vorgestellt. Im Ergebnis dieses Beitrags wird aufgezeigt, dass Fuzzing als Grundlage für das Service- Fingerprinting geeignet und sogar in Teilen den bestehenden Ansätzen, insbesondere bei der Unterscheidung von Versionen einzelner Dienste, überlegen ist. 1 Einleitung Im Hinblick auf die IT-Compliance von Unternehmen kommt der Informationssicherheit eine herausragende Bedeutung zu. In diesem Kontext stellen Penetrationstests eine wichtige Maßnahme

  • Linux Administration Time : 2½ Hrs.] Prelim Question Paper [Marks : 75
    T.Y. B.Sc. (IT) : Sem. V Linux Administration Time : 2½ Hrs.] Prelim Question Paper [Marks : 75 Q.1 Attempt any TWO: [10] Q.1 (a) Explain Linux distributions. [5] (A) Linux Distributions Although there is only one standard version of Linux, there are actually several different distributions. Different companies and groups have packaged Linux and Linux software in slightly different ways. Red Hat Linux [Any five distribution 5 marks] Red Hat Linux is currently the most popular Linux distribution. As a company, Red Hat provides software and services to implement and support professional and commercial Linux systems. Red Hat freely distributes its version of Linux under the GNU Public License. Red Hat generates income by providing professional level support, consulting, and training services. Red Hat originated the RPM package system used on several distributions, which automatically installs and removes software packages. Red Hat maintains an extensive library of Linux documentation that is freely accessible online. On its Web site, you can link to its support page, which lists the complete set of Red Hat manuals, all in Web page format for easy viewing with any Web browser. Red Hat offers several commercial products and services for business and e- commerce solutions. Mandrake Mandrake Linux is another popular Linux distribution with many of the same features as Red Hat. It focuses on providing up-to-date enhancements and an easy-to-use installation and GUI configuration. SuSE Originally a German language-based distribution, SuSE has become very popular throughout Europe and is currently one of the fastest growing distributions worldwide.

  • An Introduction to Securing Linux with Apache, Proftpd, and Samba by Zach Riggle
    Originally published in issue 1 of (IN)SECURE Magazine, get it for free in PDF format at www.insecuremag.com An Introduction to Securing Linux with Apache, ProFTPd, and Samba by Zach Riggle While the vast majority of Linux users are hard-core techies, some may be using Linux because they want to try something new, are interested in the technology, or simply cannot afford or do not want to use Microsoft Windows. After becoming acquainted with the new interface of Linux, whether KDE, Gnome, or another window manager, users may begin to explore their system. Many machines come with default installations of Apache and Samba, and a few others even include a FTP daemon. While these services may be disabled by default, some users may be inclined to use these programs. This article is a brief, but in-depth tutorial on how to keep these applications up-to-date and secure. 1. Installation First off, we’ll help out those that do not have the proper software installed. Your particular distribution of Linux may include a software management system that allows for easy installation of new software (i.e. YaST for SuSE, RPM for RedHat, and Slackpkg for Slackware). Many others feel more comfortable compiling software. Compiling is the feeding of programming code to a compiler program, which in turn creates the actual programs, or binaries, that the user actually runs. If you feel more comfortable using your Linux distribution’s custom software management, then feel free to get the software that way. If it is either not offered, or you wish to try your hand at or already know how to compile, read on.
