Linux Network Administrators Guide
Chapter 21. C News One of the most popular software packages for Netnews is C News. It was designed for sites that carry news over UUCP links. This chapter will discuss the central concepts of C News, basic installation, and maintenance tasks. C News stores its configuration files in /etc/news, and most of its binaries are kept below the /usr/lib/news/ directory. Articles are kept below /var/spool/news. You should make sure that virtually all files in these directories are owned by user news or group news. Most problems arise from files being inaccessible to C News. Use su to become the user news before you touch anything in the directory. The only exception is the setnewsids command, which is used to set the real user ID of some news programs. It must be owned by root and have the setuid bit set. In this chapter, we describe all C News configuration files in detail and show you what you have to do to keep your site running. Chapter 21. C News 402 21.1. Delivering News Articles can be fed to C News in several ways. When a local user posts an article, the newsreader usually hands it to the inews command, which completes the header information. News from remote sites, be it a single article or a whole batch, is given to the rnews command, which stores it in the /var/spool/news/in.coming directory, from where it will be picked up at a later time by newsrun. With any of these two techniques, however, the article will eventually be handed to the relaynews command. -

The Design, Implementation and Operation of an Email Pseudonym Server
The Design, Implementation and Operation of an Email Pseudonym Server David Mazieres` and M. Frans Kaashoek MIT Laboratory for Computer Science 545 Technology Square, Cambridge MA 02139 Abstract Attacks on servers that provide anonymity generally fall into two categories: attempts to expose anonymous users and attempts to silence them. Much existing work concentrates on withstanding the former, but the threat of the latter is equally real. One particularly effective attack against anonymous servers is to abuse them and stir up enough trouble that they must shut down. This paper describes the design, implementation, and operation of nym.alias.net, a server providing untraceable email aliases. We enumerate many kinds of abuse the system has weath- ered during two years of operation, and explain the measures we enacted in response. From our experiences, we distill several principles by which one can protect anonymous servers from similar attacks. 1 Introduction Anonymous on-line speech serves many purposes ranging from fighting oppressive government censorship to giving university professors feedback on teaching. Of course, the availability of anonymous speech also leads to many forms of abuse, including harassment, mail bombing and even bulk emailing. Servers providing anonymity are particularly vulnerable to flooding and denial-of-service attacks. Concerns for the privacy of legitimate users make it impractical to keep usage logs. Even with logs, the very design of an anonymous service generally makes it difficult to track down attackers. Worse yet, attempts to block problematic messages with manually-tuned filters can easily evolve into censorship—people unhappy with anonymous users will purposefully abuse a server if by doing so they can get legitimate messages filtered. -

A Proposed Technique for Tracing Origin of Spam on the Usenet
A proposed technique for tracing origin of spam on the Usenet by Dirk Bertels, BComp A dissertation submitted to the School of Computing in partial fulfillment of the requirements for the degree of Bachelor of Computing with Honours University of Tasmania June 2006 This thesis contains no material which has been accepted for the award of any other degree or diploma in any tertiary institution. To the candidate’s knowledge and belief, the thesis contains no material previously published or written by another person except where due reference is made in the text of the thesis. Signed Dirk Bertels Hobart, June 2006 Abstract The Usenet, a worldwide distributed decentralized conferencing system, is widely targeted by spammers who use a variety of techniques in order to obscure their identity. One of these techniques is called path preload, in which the path header is spoofed by means of attaching a false section at the beginning of this path. The process of detecting and confirming path preload is laborious and requires a thorough understanding of the Usenet. A technique which downloads a particular article from several servers, and compares their path headers is explored as to its usefulness regarding path preload detection. This document begins with a general background on the Usenet, highlighting those aspects that are relevant to the research, especially the topics of Usenet headers and spam. This leads to a description of the proposed technique and the development of a tool capable of implementing this technique. The tool essentially downloads a spam article from different servers, and analyses their headers.
