Others are just papers that I think are interesting. Enjoy--most are classics. <UL> <LI>Borman, D. A. 1997, "<A HREF="borman.97jan30.txt"> Re: Frequency of RST terminated connections</A>," end2end-interest Mailing List, Jan. 30, 1997. A note that the upper limit of port 5000 for the ephemeral port numbers was a typo that occurred around 1986 right before 4.3BSD was released. The upper limit was meant to be 50,000. <LI>Borman, D. A. 1997, "<A HREF="borman.97jun06.txt"> Re: SYN/RST cookies</A>," tcp-impl Mailing List, June 6, 1997. A note that the concept of the listen() backlog is a limit on the number of established connections. The purpose of this limit is to prevent TCP from accepting new connection requests when the application is not accept()ing them. <LI>Braden, R. T. 1993, "<A HREF="tcplw-extensions.txt"> TCP Extensions for High Performance: An Update</A>," Internet Draft, June 21, 1993. Unfortunately this Internet Draft expired quite a while ago and was never published as an RFC. Nevertheless, the ideas in the draft appear in all current implementations of RFC 1323. <LI>I have always been a fan of Richard W. Hamming. I did not keep very many of the textbooks that I acquired in graduate school, but kept all four of his books (along with all my Knuth, Kernighan, and Kleinrock books). Here is a wonderful <A HREF="papers.others/hammingbio.ps">biography and obituary</A> of Hamming (6 pages of PostScript), which includes a nice summary of his major accomplishments. <A HREF="gifs/hamming.html">Here</A> are the three photos that go with the biography. I will never forget having learned about digital filters from the classic Digital Signal Processing books of the 1970s (Oppenheim and Schafer, etc.) and then finding Hamming's <A HREF="http://www.amazon.com/exec/obidos/ISBN=048665088X/wrichardstevensA/"> Digital Filters</A> book, and wondering why all the classic texts made the topic so hard to understand when Hamming could make it so easy to understand. Some readers have told me that they find that my books make a complicated subject (such as network programming) easy to understand--if that is true, then it is due to the influence of writers like Richard Hamming and Brian Kernighan. <LI>Jacobson, V. 1987, "<A HREF="vanj.87jun15.txt"> Re: Interpacket Arrival Variance and Mean</A>," June 15, 1987. An explanation and example C code for estimating the mean and variance of a series of measurements. <LI>Jacobson, V. 1987, "<A HREF="vanj.87nov16.txt"> Re: Your congestion scheme</A>," Nov. 16, 1987. An early email on slow start and congestion avoidance. <LI>Jacobson, V. 1988, "<A HREF="vanj.88feb11.txt"> Dynamic Congestion Avoidance / Control</A>, Feb. 11, 1988.

These overheads contains additional details about the changes described in [Partridge 1993] and [Jacobson 1993]. Note that despite the title, these changes never made it into the 4.4BSD release. <LI>Jacobson, V. 1993, "<A HREF="ftp://ftp.ee.lbl.gov/talks/vj-nws93-1.ps.Z"> Some Design Issues for High-Speed Networks</A>," Networkshop '93, Melbourne, Australia, Nov. 1993.

A note that 4.4BSD intended to incorporate a lazy accept for TCP. <LI>Jacobson, V. 1999, "<A HREF="papers.others/vanj.99feb08.txt"> Re: traceroute history: why UDP?</A>," Usenet, comp.protocols.tcp-ip Newsgroup, Message-ID: &lt;79m7m4$reh$1@dog.ee.lbl.gov&gt;, Feb. 8, 1999. People have wondered why traceroute uses UDP probes instead of ICMP echo probes (which apparently Microsoft traceroute uses). Here is the answer from the original author. <LI><A HREF="http://www.cs.bell-labs.com/who/bwk/index.html">Brian Kernighan's</A> home page contains some classic software along with the source code for the one true awk. (I am a big fan of awk, and use it a lot.) <LI>Readers (and copy editors) are occasionally surprised by my use of compound words, instead of using either the open or hyphenated form. That is, I write filesystem instead of either file system or file-system. The Chicago Manual of Style acknowledges this trend (Section 6.38). Don Knuth has a wonderul <A HREF="papers.others/knuth.email.html">paragraph</A> about why we should write email instead of e-mail and just accept the fact now that it will become a compound word. <LI>Lanciani, D. 1996, "<A HREF="lanciani.96apr10.txt"> Re: sockets: AF_INET vs. PF_INET</A>," Usenet, comp.protocols.tcp-ip Newsgroup, Message-ID: &lt;3561@news.IPSWITCH.COM&gt;, Apr. 1996. Contains a copy of the 4.1cBSD manual page for the original socket() function, showing why the PF_ constants existed, independent of the AF_ constants. <LI>Libes, D. 1990, "<A HREF="libes.timers.txt"> Implementing Software Timers</A>," C User's Journal, Nov. 1990. A handy set of C functions to implement any number of software timers in a process using a single timer signal. <LI>Maslen, T.

An interesting history of the development of the Solaris gethostbyXXXX_r() functions. <LI>Mogul, J. 1992, "<A HREF="mogul.92mar02.txt"> Re: Holy Turbocharger Batman, (evil, cheating) NFS async writes fly</A>," Usenet, comp.protocols.nfs Newsgroup, Message-ID: &lt;1992Mar2.191711.9935@PA.dec.com&gt;, March 1992. <LI>Muuss, M. J., "<A HREF="http://ftp.arl.mil/~mike/ping.html"> The Story of the PING Program</A>." A history of the PING program, by its original author. There exists a children's book <A HREF="http://www.amazon.com/exec/obidos/ISBN=0140502416/wrichardstevensA/"> The Story About Ping</A>, that, sadly, is not about this command. Nevertheless, a funny <A HREF="papers.others/ping.amazon.html">review</A> of this book was posted to Amazon in March 1999. Amazon promptly removed the review (no sense of humor?), then put it back. <LI>Partridge, C. 1993, "<A HREF="vanj.93sep07.txt"> Jacobson on TCP in 30 Instructions</A>," Usenet, comp.protocols.tcp-ip Newsgroup, Message-ID &lt;1993Sep8.213239.28992@sics.se&gt;, Sept. 1993. <LI>Partridge, C., and Pink, S. 1993. "<A HREF="fasterudp.ps"> A Faster UDP</A>," IEEE/ACM Transactions on Networking, vol. 1, no. 4, pp. 429-440 (PostScript, 148K). <LI>This is a summary of the accidental priority inversion that occurred with the Mars <A HREF="papers.others/pathfinder.html">Pathfinder</A> mission in July, 1997. This summary is by Mike Jones, dated December 7, 1997, and was then widely circulated after it appeared in Peter G. Neumann's moderated Risks Forum (comp.risks) on December 9, 1997 in issue RISKS-19.49. <LI>Paxson, V. 1995, "<A HREF="paxson.95sep29.txt"> Re: Traceroute and TTL</A>," Usenet, comp.protocols.tcp-ip Newsgroup, Message-ID &lt;48407@dog.ee.lbl.gov&gt; Sept. 1995. 30% of measured Internet routes are asymmetrical.

Whenever I teach RPC I always mention that it is a controversial topic. This is a collection of eight postings by some knowledgeable people on the topic of RPC, some pro, some con. This discussion was generated by the proposal from Sun to publish their RPC specifications as RFCs (which were published as RFCs <A HREF="ftp://ftp.isi.edu/in-notes/rfc1831.txt">1831</A>, <A HREF="ftp://ftp.isi.edu/in-notes/rfc1832.txt">1832</A>, and <A HREF="ftp://ftp.isi.edu/in-notes/rfc1833.txt">1833</A>, preceded by the agreement detailed in RFC <A HREF="ftp://ftp.isi.edu/in-notes/rfc1790.txt">1790</A>). <LI>Torek, C. 1994, "<A HREF="torek.94dec31.txt"> Re: Delay in re-using TCP/IP port</A>," Usenet, comp.unix.wizards Newsgroup, Message-ID &lt;199501010028.QAA16863@elf.bsdi.com&gt;, Dec. 1994.

(1.4 Mbytes PostScript, 185 pages.) This paper and the next two are the only publicly available documentation that I am aware of for the System V Release 4 STREAMS interfaces to the datalink layer, network layer, and transport layer.

"<A HREF="papers.others/rfc707.txt"> A High-Level Framework for Network-Based Resource Sharing</A>," RFC 707, Dec. 1975. This is probably one of the first papers describing RPC (remote procedure calls). Most RFC indexes list this RFC as not being on-line, but someone found a copy of it for posterity. This paper also appeared in the Proceedings of the National Computer Conference in June 1976, and that is how it is normally referenced in RPC papers and texts. </UL> <HR> <H2><A NAME="typesetting">Typesetting</A></H2> This section contains some notes on how I write books. <UL> <LI><A HREF="pagelayout.html">Page layout</A>. <LI><A HREF="indexing.html">Indexing</A>. <LI><A HREF="chartjunk.html">Chartjunk</A>. </UL> <HR> <H2><A NAME="sources">Miscellaneous Source Code</A></H2> <UL> <LI>This used to be a tar file containing the Posix.1g <TT>getaddrinfo()</TT> function that supports both IPv4 and IPv6.

(1978) and Ph.D. (1982) in Systems Engineering (image processing major, physiology minor) from the University of Arizona. I have had many lives as a programmer. After getting my B.S.E. I spent 2 years writing operating systems in assembler, 7 years in the astronomy world (at Kitt Peak National Observatory in Tucson, doing real-time data acquisition and image processing), then 8 years as Vice President of a health-care software startup in Connecticut (Health Systems International). Since 1990 I have been self-employed, living in Tucson, writing books full-time with occasional teaching of classes based on the books. In what seems to be a previous life (1970s) I was a flight instructor, although most of my flying these days is in the back of a commercial airliner or down the steeps at Taos Ski Valley. I am willing to admit that my first programming language was Fortran, that I once programmed in Forth and Cobol, and that I still have (from my undergraduate years) both my IBM green card and my slide rule (which Kelly Johnson calls a "Michigan calculator"). Here is a <A HREF="bio1.html">longer biography</A>, mainly about how I got into computers and Unix. Here is a chronological list of the various <A HREF="bio3.html">computer systems and programming languages</A> that I have used. <H2>Where are you from?</H2> Chronologically and geographically I have lived lots of places. When someone asks me "where are you from?" or "where did you grow up?" my reply begins with "it's a long story". <UL> <LI>1951: I was born in Luanshya, Northern Rhodesia (now Zambia). My father (an American, although he had spent much of his youth in Southern Africa and Tasmania) was working at the Roan Antelope Copper Mine, where he had worked as a metallurgical engineer since graduating from Columbia University in 1937. My mother (also an American) had gone to Northern Rhodesia to visit her brother (another mining engineer from Columbia), met my father, got married, and stayed 16 years longer than planned. <LI>1956-1960: Salt Lake City, Utah. My father was working for Kennecott Copper Corp. (Bingham Canyon). <LI>1960-1964: Hurley, New Mexico. My father was working for Kennecott Copper Corp. (Chino Mines). <LI>1964: Washington, D.C. My father was at the Brookings Institution for 6 months. <LI>1964-1971: Phalaborwa, South Africa. My parents went to South Africa for the development and opening of the new Palabora Copper Mine in the northeastern Transvaal. (Phalaborwa is one of the gates into the Kruger Game Reserve.) <LI>1964-1968: Waynesboro, Virginia. When my parents moved to South Africa I was about to start high school, and had my choice of a boarding school in the U.S. or an English-style boarding school in South Africa. I chose the former and attended Fishburne Military School for 4 years, going "home" to South Africa each summer. <LI>1968-1973: Ann Arbor, Michigan, attending the University of Michigan. <LI>1969: Sallisaw, Oklahoma. I had a summer job with Bechtel Corp. at the construction of the Kerr McGee uranium treatment plant in Gore, OK. <LI>1971, 1972: Carrollton, Georgia. I had summer jobs with the Southwire Corp., the first summer as a computer operator, and the second summer as a programmer. <LI>1973-1975: Santa Ana, California. After graduating from Michigan, I worked for 2 years at Singer's M & M Computer Division as a programmer. <LI>1975-1982: Tucson, Arizona. I worked full-time for Kitt Peak Observatory and attended graduate school at the University of Arizona. Yes, it is possible to obtain a Ph.D. while working full-time, although you don't have much free time. <LI>1982-1990: New Haven, Connecticut. I worked for Health Systems International. <LI>1990-present: Tucson, Arizona. </UL> <HR> <A HREF="http://www.bsdi.com/"> <IMG SRC="http://www.kohala.com/start/gifs/bsdi400x80.gif" ALIGN="LEFT" ALT="powered by BSDI logo" WIDTH=400 HEIGHT=80> </A> <A HREF="http://validator.w3.org/check?uri=http://www.kohala.com/start/index.html"> <IMG BORDER=0 SRC="http://www.kohala.com/start/gifs/vh40.gif" ALIGN="RIGHT" HEIGHT=31 WIDTH=88 ALT="Valid HTML 4.0!"> </A> </BODY> </HTML>
