Einleitung 2 System Administration: It’s a dirty job, but someone said I had to do it. Aufgaben eines Sysadmin gestern und heute: Früher Heute − Einrichten von neuen Nutzern Auch heute gibt es neue User per Hand mit Scripte, Oberflächen automatisiert − Druckermanagment Tonerpatrone Wechseln, Druckerjobs canceln, Drucker reaktivieren, Nutzer beruhigen, Das ist immer noch so. "Der Drucker druckt nicht, ich habe nichts gemacht." − Fragen beantworten: "Wie kann ich ....?" Die Nutzer lesen immer Das "Dialog−Manual" noch keine Manuals. − Prozesse killen Auch heute sollen Prozesse noch endlos laufen. 12/04/13 1. Einleitung 3 Früher Heute − Prozesse/Daemone nach Möglich, aber es gibt Absturz neu starten auch Überwachungstools − Tastaturen aktivieren kommt seltener vor − Backups veranlassen Die Datenmengen sind (zeitzyklisch, häufig) nur viel größer. − Restore von Files Auch heute löschen Nutzer ihre Files unabsichtlich. − "Mein Rechner macht nichts mehr!!!!" Passiert seltener, da die Monitoring/Tracing Rechner schneller sind und mehr Prozessoren haben, gibt es dieses Problem nicht so oft. − Rebooting von Systemen Alle zwei bis drei Jahre kommt bei Fehlern so etwas noch vor. − Speicherplatz auf Platten schaffen Jeder erfüllte Wunsch erzeugt Hilferuf: "Ich kann nichts mehr viele neue kleine Wünsche speichern!!!!" − Sicherheitslöcher finden und Schlimmer als je zuvor, beseitigen, Einbrecher suchen dank Internet und verfolgen 12/04/13 1. Einleitung 4 Früher Heute − Passwörter prüfen Nicht mehr nötig dank neuer Technologien − Programme installieren Es soll auch heute noch neue Programme geben. Einheitliche Verfahren erleichtern aber die Arbeit. − Betriebssystemupdates Vereinfacht. − Konfiguration des Rechnernetzes ja − Installieren neuer Rechner.

  • Comparing UNIX with Other Systems
    Comparing UNIX with other systems Timothy DO' Chase Corporate Computer systems, Inc. 33 West Main Street Holmdel, New Jersey he original concept behind this article was to make a grand comparison between UNIX Tand several other well known systems. This was to beall encompassing and packed with vital information summarized in neat charts, tables and graphs. As the work began, the realization settled in that this was not only difficult to do, but would result in a work so boring as to beincomprehensible. The reader, faced with such awealth ofinformation would be lost at best. Conclusions would be difficult to draw and, in short, the result would be worthless. Mtertearfully filling my waste basket with the initial efforts, I regrouped and began by as­ king myself why would anyone be interested in comparing UNIX with another operating system? There appears to be only two answers. First, one might hope to learn something about UNIX by analogy. IfI understand the file system on MPEN and someone tells me that UNIX is like that except for such and so, then I might be more quickly able to under­ stand UNIX. This I felt was an unlikely motivation. After all, there are much simpler ways to learn UNIX. Instead, the motivation for comparing UNIX to other systems must come from a need to evaluate UNIX. Ifwe are aware of the features or short comings ofother systems, then we can benefit by evaluating UNIX relative to those systems. Choosing an operating system or computer is a major decision which we can benefit from or be stuck with for a long time.

  • Operating System Selection
    EARTH STATION CONTROL COMPUTER - OPERATING SYSTEM SELECTION D. Varney and L. D'Ad.dario June 11, 1991 Abstract This report describes a survey of real-time operating systems that may form a suitable platform for construction of the control software for the Green Bank OVLBI Earth Station. After considering the performance requirements, desire for standardization, hardware and software costs, and several other factors, we have selected Venix, by VenturCom, Inc. This includes a fully-preemptable real-time kernel that is compliant with UNIX interface standards, including SVID, Posix 1003.1 and 1003.4, and ABI/386. It runs on 80386 processors in the IBM-AT architecture. 1 Introduction The software requirements for the OVLBI Earth Station control computer were outlined in OVLBI- ES Memo No. 8. In the present memo, we discuss the implications for the choice of operating system (OS), evaluate several candidate OS's, and report the final selection. This will have a strong effect on the choice of hardware platform, which will be discussed in a subsequent memo. The main requirements on the OS are (1) that it provide good real-time performance for time- critical tasks, including predictable interrupt response and task switching times regardless of system loading; and (2) that it provide good support for networking, both local-- and wide-area, including the protocols commonly used at the NRAO for remote access and file transfer, namely TCP/IP. To this we add a desire for good debugging facilities to ease development, especially for real-time tasks. UNIX has become the most standard and portable operating system available.

    Oh, the Places UNIX'll Go! (With apologies to Dr. Seuss) Oh the places UNIX'll go we'll start from its birth A replacement for MULTICS, a system of great girth The UNiplexed Information and Computing Service (UNICS for short) A programmer's workbench, not much of import It started off life on the PDP-7 Unnamed 'till it reached the PDP-11 With 16bit “mostly orthogonal instruction set” This little-used machine did UNIX beget The system grew to fit several needs Research, Word Processing, and Space Travel deeds The system took form on the PDP-11 (The oldest machine to run UNIX V7) But assembly code is hard to maintain And with UNIX came something to ease that pain “Complex systems must use assembly for everything” they cried But The C Programming Language cast that claim aside UNIX was written in C by v8 And with it the chance for UNIX to migrate Ritchie and Thompson presented UNIX to all in 1973 But Bell couldn't monetize it because of a 1956 consent decree So UNIX was shipped on magnetic tapes And all sorts of media of all sorts of shapes The souorce was available on an “as-is” basis Find a copy of “Lions'” and we're off to the races UNIX for teaching and educational use Version 6 set UNIX's commercial side loose Development was quick and the patches released Sometimes without letting the attorneys say their peace UNIX was on DEC but Bell Labs felt restricted Bell bought an Interdata 8/32 to see DEC evicted And then UNIX ran as a VM/370 guest UNIVAC 1100 and Intel 8086 (custom MMU blessed) Near the end of the '70s UNIX showed up in places It even brought smiles to ARPA's faces But the 1980s would start UNIX's spiral For that is when plucky UNIX went viral Oh, the places UNIX'll go, to thousands of sites They even were noticed by the magazine BYTE Companies "may support other [operating] systems”, it's true “but a Unix implementation always happens to be available".

PREFACE Page 1 PREFACE Kermit is the name of a protocol for transferring files from one computer to another over ordinary asynchronous terminal connections. Kermit programs have been written for many different computers, and in general any two computers that have Kermit programs can exchange sequential files correctly and completely. This manual gives a brief and general overview of what Kermit is and how to use it, but consists mostly of detailed instructions for use and installation of specific Kermit programs. For a more detailed introduction to Kermit, complete with illustrations, diagrams, and tutorials, consult the book Kermit, A File Transfer Protocol, by Frank da Cruz, Digital Press, Bedford MA (1987), ISBN 0-932376-88-6, DEC order number EY-6705E-DP (phone 1-800-343-8321). The Kermit book describes Kermit in detail, from the points of view of the beginner, the user, the computer professional who must install Kermit programs or support their use, and the programmer who wishes to write new Kermit implementations. Also included are general introductions to computers, data communications, and file organization, plus a detailed troubleshooting guide, bootstrapping hints, and various appendices and tables. The latter half of the book is taken up by a complete description of the Kermit file transfer protocol, with programming examples in the C language, plus some analysis and comparisons of Kermit with other popular protocols such as Xmodem.
