Networking for Systems Administrators

Networking for Systems Administrators

Stop waiting for the network team!If basic TCP/IP was hard, network administrators couldn't do it. Servers give sysadmins a incredible visibility into the network-once they know how to unlock it. Most sysadmins don't need to understand window scaling, or the differences between IPv4 and IPv6 echo requests, or other intricacies of the TCP/IP protocols. You need only enough to deploy your own applications and get easy support from the network team.This book teaches you* How modern networks really work*The essentials of TCP/IP*The next-generation protocol, IPv6* The right tools to diagnose network problems, and how to use them*Troubleshooting everything from the physical wire to DNS* How to see the traffic you send and receive* Connectivity testing* How to communicate with your network team to quickly resolve problemsA systems administrator doesn't need to know the innards of TCP/IP, but knowing enough to diagnose your own network issues will transforms a good sysadmin into a great one.Fungi are among the most networked creatures in the world. If a mushroom can do it, so can you!

TCP/IP Network Administration

Help for Unix System Administrators

TCP/IP Network Administration

This complete guide to setting up and running a TCP/IP network is essential for network administrators, and invaluable for users of home systems that access the Internet. The book starts with the fundamentals -- what protocols do and how they work, how addresses and routing are used to move data through the network, how to set up your network connection -- and then covers, in detail, everything you need to know to exchange information via the Internet.Included are discussions on advanced routing protocols (RIPv2, OSPF, and BGP) and the gated software package that implements them, a tutorial on configuring important network services -- including DNS, Apache, sendmail, Samba, PPP, and DHCP -- as well as expanded chapters on troubleshooting and security. TCP/IP Network Administration is also a command and syntax reference for important packages such as gated, pppd, named, dhcpd, and sendmail.With coverage that includes Linux, Solaris, BSD, and System V TCP/IP implementations, the third edition contains: Overview of TCP/IP Delivering the data Network services Getting startedM Basic configuration Configuring the interface Configuring routing Configuring DNS Configuring network servers Configuring sendmail Configuring Apache Network security Troubleshooting Appendices include dip, ppd, and chat reference, a gated reference, a dhcpd reference, and a sendmail reference This new edition includes ways of configuring Samba to provide file and print sharing on networks that integrate Unix and Windows, and a new chapter is dedicated to the important task of configuring the Apache web server. Coverage of network security now includes details on OpenSSH, stunnel, gpg, iptables, and the access control mechanism in xinetd. Plus, the book offers updated information about DNS, including details on BIND 8 and BIND 9, the role of classless IP addressing and network prefixes, and the changing role of registrars.Without a doubt, TCP/IP Network Administration, 3rd Edition is a must-have for all network administrators and anyone who deals with a network that transmits data over the Internet.

Principles of Network and System Administration

Principles of Network and System Administration

Burgess approaches both network and system administration from theperspective of principles and ideas which do not change on aday-to-day basis. A great deal of attention is paid to the heuristics of systemand network administration; technical and sociological issues aretaken into account equally and are presented thoughtfully with aneye to teaching not what to do as a system or networkadministrator, but how to think about problems that arise inpractice. As a result, the author keeps the reader looking forwardto what comes next and how to implement what he or she haslearned. The focus is on strategic issues, how to keep systemsmaintainable and how to manage configuration files across anenterprise. During the 80s and most of the 90s the frontiers ofsystem administration were about understanding what the jobentailed and building tools in order to manage networks moreefficiently. The next phase is about standardization ofmanagement and practice, making system administration more formaland less ad hoc, and Burgess' book is one of the first tobegin to push into this area.

Handbook of Network and System Administration

Handbook of Network and System Administration

System administration is about the design, running and maintenance of human-computer systems. Examples of human-computer systems include business enterprises, service institutions and any extensive machinery that is operated by, or interacts with human beings. System administration is often thought of as the technological side of a system: the architecture, construction and optimization of the collaborating parts, but it also occasionally touches on softer factors such as user assistance (help desks), ethical considerations in deploying a system, and the larger implications of its design for others who come into contact with it. This book summarizes the state of research and practice in this emerging field of network and system administration, in an anthology of chapters written by the top academics in the field. The authors include members of the IST-EMANICS Network of Excellence in Network Management. This book will be a valuable reference work for researchers and senior system managers wanting to understand the essentials of system administration, whether in practical application of a data center or in the design of new systems and data centers. - Covers data center planning and design - Discusses configuration management - Illustrates business modeling and system administration - Provides the latest theoretical developments
