TCP/IP Network Administration

This complete guide to setting up and running a TCP/IP network is aimed at network administrators, as well as 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 (RI Pv2, 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. The book 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, this third edition contains: overview of TCP/IP; delivering the data; network services; getting started; 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 edition also 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.
