É imprescindível para o bom funcionamento de um ambiente de rede a existência de um mecanismo para monitorizar o desempenho fornecendo dados confiáveis para uma atuação do administrador. As plataformas de gerência e administração de redes UNIX comerciais e acadêmicas existentes possuem vantagens e deficiências, muitas vezes preteridos por comandos e utilitários isolados devido a sua rapidez e agilidade. Idealmente, tal ferramenta deve ser simples, fácil de usar, de baixo impacto na máquina e na rede, portátil, capaz de traduzir informação de alta qualidade e de fácil extensibilidade para os requisitos locais, automatizando portanto algumas ações do administrador.SIMON (Sistema de Monitorização), apresentado nesta dissertação, obtém um bom compromisso entre tais qualidades, utilizando uma interface Java para fornecer os dados coletados de maneira mais amigável, otimizando assim o desempenho de ambos, rede e administrador. / Abstract: Due to the existence of several variants of the UNIX operating system and to the increasing hardware diversity, administering networked systems is a continuous, most1y complex, task. For good working conditions in a networked environment, it is a necessary requirement the availability of a mechanism to monitor performance and to supply reliable data for the administrator' s actions. Current commercial and academic platforms for UNIX network management and administration have both advantages and drawbacks, at times being overlooked in favor of more simple commands and utilities for their quickness. The ideal tool should be simple, easy to use, of low impact on both the machine and the network, portable, able to convey high quality information and easily extendable to cover local requirements, thus automating some of the administrator' s actions. SIMON, presented in this dissertation, yields a good compromise from the above mentioned features; it uses a Java interface to supply collected data in a more mendly way, thus optimizing the performance of both the network and the administrator. / Mestrado / Mestre em Ciência da Computação

Different computer systems have their own ways of representing, storing and managing files. One approach to facilitate file transfers among systems in a heterogeneous networked environment is for each system to locally map files for transfer onto a virtual filestore (VFS). Conceptually, a virtual filestore provides a universal model for describing files and how they can be manipulated. The ISO File Transfer, Access and Management (FTAM) protocol offers one such virtual filestore model. This thesis reports on the prototype implementation of a useful subset of the ISO FTAM protocol for the UNIX 4.2 BSD¹ file system. We call this implementation ubcFTAM. UNIX files, ordinarily regarded as unstructured, can be endowed with some internal structure thereby allowing the transfer of selective portions of a file. Furthermore, the implementation offers several file attributes not supported by UNIX. ubcFTAM runs on several Sun Workstations² interconnected by a 10 Mbps Ethernet. Some performance data of ubcFTAM are also presented. This thesis also identifies several aspects of the specifications that are ambiguous or that are inadequate, warranting further studies. Resolutions for these issues are discussed. We hope this experience will be useful to others planning to implement FTAM for UNIX systems. ¹UNIX is a registered trademark of American Telephone and Telegraph Bell Laboratories.

Berkeley UNIGRAFIX is a graphics system that runs under the UNIX operating system. It comprises a collection of rendering programs and scene generating programs. Scenes of objects are described in a terse, human-readable format called the UNIGRAFIX descriptive language. In order to display parametric curves and surfaces using UNIGRAFIX, we developed a scene generator called UGTRACE. It traces a set of parametric equations and generates a scene file written in the UNIGRAFIX format. Two tracing modes as well as two displaying modes were designed. The Berkeley UNIGRAFIX system was installed in the McMaster environment. For our purpose, we also modified the various device drivers of UGDISP, the latest version of the renderers. Available output devices include the AED colour graphics terminal, the IMAGEN laser printer and the IBM PC emulating a Tektronix 4010 terminal. UGDISP is used to display scene files generated by UGTRACE. / Thesis / Master of Science (MSc)

Visando estudo do método de sísmica multicomponente (3C) na investigação rasa, foram adquiridos dados em duas áreas urbanas da cidade de São Paulo, Brasil, com características geológicas diferentes: Campus da Universidade de São Paulo (USP), situado na zona oeste do município e área da estrutura de Colônia, situada na região de Parelheiros, na zona periférica do município. Na aquisição foram empregados geofones de 3 componentes com frequência natural de 10 Hz e, como fontes sísmicas, o compactador e o impacto de uma marreta. Para realizar o processamento dos dados foi utilizado o pacote Seismic Unix (CWP/SU). Foi observada uma marcada diferença nas respostas dos subsolos entre os dois sítios. Nos dados adquiridos no Campus da USP foram observadas tanto as ondas PP como as ondas convertidas (PSv), no entanto, nos dados obtidos em área de Colônia, não foi possível visualizar as ondas convertidas. A partir das secções da onda PP e da onda PS foi estimada a razão Vp/Vs assim como o coeficiente de Poisson para a área da USP. / In order to study the multicomponent seismic method (3C) to shallow investigation, two data sets were acquired in urban areas of São Paulo city, Brazil, with different geological characteristics. The area of the Campus of São Paulo University (USP) is located in the western part of the city and the area of the structure of Colônia is located in the region of Parelheiros, a peripheral zone of São Paulo. For the data acquisition, it were employed 3C-geophones of 10 Hz and, as seismic sources, hand-operated surface compactor and sledge hammer. For processing were used the Seismic Unix package (CWP / SU). It was observed a marked difference in the subsoil responses between the two sites. In the data acquired in the Campus of USP, both PP waves and converted waves (PSv) was observed; however, in the data obtainedin the Colônia area, it was not possible to visualize the converted waves. For the USP area, the Vp / Vs ratio and Poisson ratio were estimated.

Syftet med detta arbete har varit att utforma enlaborationsinstruktion som förmedlar teori och kunskap omframförallt Kerberos, ett autentiseringssystem, och LDAP, enkatalogsystem. Arbetet försökte även bena ut vilka LDAPservrarsom är de vanligast förekommande bland företag ochorganisationer. Rapporten börjar med att behandla den teorisom krävs för att kunna implementera ett system somautentiserar användare via Kerberos och som tillhandahålleranvändarinformation via LDAP samt hur dessa kan kopplastill olika tjänster.Med hjälp av teorin implementerades ett system i virtuellmiljö med Ubuntu och utifrån denna implementation samtteorin utformades en laborationsinstruktion kring ämnet. Enenkät kring vilken LDAP-server som används på detillfrågades företag skapades och skickades ut tillslumpmässigt utvalda företag och visade att alla de tillfrågadeanvände sig av Microsofts Active Directory. Den visade ävenatt en tredjedel av de tillfrågade använde sig av Open Sourcevarianterav LDAP som just detta arbete fokuserar på.Slutligen konstateras att LDAP är den huvudsakligafokuspunkten för teorin och att om studenterna får grepp omLDAPs utformning och struktur faller många av de övrigabitarna på plats och underlättar förståelsen när de senareimplementerar systemet i praktiken. / The aim of this work has been to design a laboratoryassignment that conveys the theory and knowledge ofparticularly Kerberos, an authentication system, and LDAP,a directory system. The work also tried to sort out whichLDAP servers that are the most common among businessesand organizations. This work begins with treating the theoryrequired to implement a system that authenticates the uservia Kerberos and provides user information via LDAP andhow these can be linked to different services. With thisknowledge I implemented a system in a virtual environmentwith Ubuntu and based on this implementation as well astheory, designed a laboratory assigment on the subject. Aquestionnaire on which LDAP servers that are used by thequestioned companies were created and sent out torandomly selected companies and showed that allrespondents used Microsoft Active Directory. It also showedthat one third of respondents used the Open Source versionsof LDAP that this report focuses on. Finally the the reportconcludes that LDAP is the main focal point of the theory,and that if the students get a grip on LDAPs layout andstructure many of the other pieces will fall in place andfacilitate understanding when they later implement thesystem in practice.
