NWG/RFC# 752 MRC 2-Jan-79 01:22 nnnnnA Universal Host TableNetwork Working Group Mark CrispinRequest for Comments 752 SU-AINIC nnnnn 2 January 1979A Universal Host TableABSTRACT: The network host table in use at MIT and Stanford is described.This host table is superior to the NIC and Tenex host tables in severalways. A binary file, compiled from this host table, is also described.This file is used by subsystems on MIT's ITS and Stanford's WAITStimesharing systems for efficiency in host and network lookups.HISTORY: As with many other sites on the Arpanet, we found the NIC's hosttable unsuited to our needs. Part of the problem was because the NIChost table was often inaccurate and all too often failed to includeseveral nicknames in common usage in our communities. In addition, theNIC host table's format was awkward for user programs to use, especiallythose which wanted to have the host table mapped into memory in somesort of structured binary form for efficient lookups. Finally, the NIChost table neglects to include some essential information. The ITS host table was originally designed to be compiled alongwith a network handling program (MIDAS, the PDP-10 assembler used, has apseudo-op to insert a file into an assembly). In order to make the hosttable palatable to the assembler, every comment line began with asemicolon, and every actual data line began with the word HOST. Eachprogram which used the host table defined HOST as an assembly macrobefore inserting the host table into the assembly. This worked well for a long while, but as the network grew, hostschanged their status more frequently and more network programs requiredreassembly when the host table was updated. If the appropriate personfor a particular subsystem was not around, it could be a while beforethat subsystem updated its host table. In the spring of 1977, design started on a binary file which wouldbe placed on a system directory and which all subsystems which wanted toaccess host table information would read in. The format was carefullydesigned to be general enough to satisfy the needs of all the diversesubsystems. All of these subsystems required modification to use thenew format but these modifications turned out to be trivial compared tothe benefits from not having to recompile every subsystem. Later the host table and binary file were imported to the WAITSMark Crispin [page 1]
NWG/RFC# 752 MRC 2-Jan-79 01:22 nnnnnA Universal Host Tablesystem at Stanford, where it eventually replaced the former host table.Recently, support for multiple networks has been added, includingallowing hosts to be on more than one network, and a more flexiblecompiler than assembler macros was written (the program which generatesthe binary file now does the compiling).THE HOST TABLE: In the descriptions below, angle brackets and lower case are usedas a meta-linguistic device. It should be noted that spaces and tabsare often ignored and may be used freely in the source format, whilecommas are always explicit delimiters. In addition, semicolon alwaysbegins a commentary and everything after the semicolon on the line isignored; however, any text before the semicolon on the line is processedas usual. The syntax rules should be obvious by examining the text ofthe host table in the appendix. Names are alphanumeric strings,consisting of the set (A-Z, 0-9, and - (i.e., dash)). Quoting is usedto separate examples from the text and is not part of the example. The host table consists of commentary and two types of text lines.The commentary lines begin with a semicolon and are ignored by thecompiler. They are intended to provide information for a human readeror editor of the host table. The commentary lines may be in mixed case,however the text lines are by tradition entirely in upper case. Thereare two kinds of text lines: host and network. Network text lines begin with the word "NET" followed by a space ortab. These specify a network name and the network number (as assignedby Postel) for that network. As there currently are no officiallyassigned network names, suitable names were assigned more or less basedon the English names in Postel's "Assigned Numbers",RFC 750. Thesenames may be changed in the future (however, some software has come todepend on the names ARPA, CHAOS, and DIAL for the ARPANET, Chaos net,and Dialnet). The format of a network text line is:NET <name>,<decimal-number> For example, the ARPANET's entry would look something like:NET ARPA,10 Host text lines begin with the word "HOST" followed by a space ortab. These specify a host name, a host address list, whether this hostis a "user" or a "server", the name of the host's operating system, thename of the host's machine type, and a nick name list. The operatingsystem, machine type, and/or nick name list may be omitted, in whichcase they default to unknown or null.Mark Crispin [page 2]
NWG/RFC# 752 MRC 2-Jan-79 01:22 nnnnnA Universal Host Table The host name is a unique name string for that host. For ARPANETsites, it is the official name for that host as assigned by the NIC.For other networks, it is whatever name is in common use on thatnetwork. So far there haven't been any naming conflicts onmultiple-network hosts. The host address list is either a single host address, or a list ofhost addresses in square brackets and delimited by commas. A hostaddress consists of a network name, a space, and the host's address onthat network. If the network name is not specified, it defaults to ARPA(i.e., "ARPA 0/11" and "0/11" are equivalent). Different networks parsehost addresses in different ways: ARPANET addresses are in BBN-style host number slash IMP number notation, with both numbers being decimal. Hence host 2 on IMP 6 is represented as "2/6". Of course, this format is backwards, but it has become enough of a network standard to force its use. Old-style octal addresses are allowed (e.g. "206" for "2/6") but are no longer used or supported. CHAOS net addresses are a single octal number, e.g. "CHAOS 2026", and specify the host's address on the CHAOS net. Dialnet addresses are a ten-digit decimal number, and specify the TelCo (phone) number of the host's Dialnet port. The definition of user vs. server is generally taken to mean"according to the NIC" for ARPANET hosts. A server is considered to bea host for which making a connection to a remote service is a meaningfuloperation. For some hosts with limited servers, the definition often ischanged from the official one, depending upon the individualcircumstances. For example, "users" who have an FTP server andoccasionally a TELNET server may be called "servers". On the other handa "server" which does not accept MAIL and rejects MAIL in a pathologicalway (e.g. by hanging) might be labelled a "user". The name of the host's operating system is a string much as thehost name is, such as "ITS", "TOPS-20", or "MULTICS". Some subsystemsuse this information to predict certain behavior of the remote server.For example, a MAIL user subsystem knows that for operating system"MULTICS" it has to log in as user NETML before attempting to deliverthe mail. The name of the host's machine type is a string as well. For theconvenience of several subsystems, all DEC "PDP-n" machines are enteredwithout the dash, and all PDP-10 like machines (e.g., KL-20, MAXC, etc.)are considered to be PDP-10's, which by the way gets entered as "PDP10"since that is a single 36-bit word in 7-bit ASCII. Like the operatingsystem name, several subsystems use this information as well. Forexample, a PDP-10 FTP user process will try to negotiate 36-bit imageMark Crispin [page 3]
NWG/RFC# 752 MRC 2-Jan-79 01:22 nnnnnA Universal Host Tablemode with another PDP-10; or a Tenex or Tops-20 site will try tonegotiate paged transfers with another Tenex or Tops-20. The nick name list is in square brackets and consists of a seriesof names delimited by commas. There may be any number of nick names. The format of a host text line is:HOST <name>,<address-list>,<status>,<system>,<machine>,<nickname-list> For example, an entry might look something like:HOST MIT-AI,[ARPA 2/6,CHAOS 2026],SERVER,ITS,PDP10,[AI,MITAI]this entry describes a host named "MIT-AI" on two networks (ARPANET andCHAOS net), with ARPANET address "2/6" and CHAOS net address "2026". Itis a server site, running an operating system called "ITS" on "PDP10"hardware. It has two nicknames, "AI" and "MITAI".THE HOST TABLE BINARY FILE: The host table binary file is a 36-bit data file; consequently itprobably is only of interest to PDP-10 sites. The format of the fileis: FILE HEADER:word 0 The name of this file in SIXBIT. Currently HOSTS2.word 1 The name of the source file in SIXBIT. Always HOSTS.word 2 The version of the source file in SIXBIT if compiled on an ITS site, otherwise the name of the site in SIXBIT.word 3 The directory name of the source, usually in SIXBIT.word 4 The name of the site in SIXBIT.word 5 The user name who compiled the file, usually in SIXBIT.word 6 Date of compilation as SIXBIT YYMMDD.word 7 Time of compilation as SIXBIT HHMMSS.word 8 Address in file of NAME table.word 9 Address in file of SITE table.word 10 Address in file of NETWORK table. <words after this are reserved for future use> NETWORK table:word 0 Number of entries in table.word 1 Number of words per entry, currently 2. entry word 0 Network number assigned by Postel. entry word 1 Left half: Address in file of name of network in ASCIZ. Right half: Address in file of network's ADDRESS table (zero means no ADDRESS table, i.e. no hosts).Mark Crispin [page 4]
NWG/RFC# 752 MRC 2-Jan-79 01:22 nnnnnA Universal Host Table ADDRESS table (one per network):word 0 Number of entries in table.word 1 Number of words per entry, currently 2. entry word 0 Network address of this entry, including network number. For ARPANET addresses this is in the format: xxx000,,000000 Network number 000xxx,,xxx000 IMP number 000000,,000xxx Host number Each number is right justified. For CHAOS net addresses it is an octal number. For Dialnet addresses it is the address in the file of the TelCo number in ASCIZ. entry word 1 Left half: Address in file of SITE table entry. Right half: Address in file of next ADDRESS table entry for this site (zero means end of list). SITE table:word 0 Number of entries in table.word 1 Number of words per entry, currently 3. entry word 0 Left half: Address in file of official name in ASCIZ. Right half: Address in file of first ADDRESS table entry for this site. entry word 1 Left half: Address in file of operating system name in ASCIZ (zero means unknown). Right half: Address in file of machine type in ASCIZ (zero means unknown). entry word 2 Left half: Flags. The 400000 bit means a server site. Right half: reserved NAMES table:word 0 Number of entries in table.word 1 Number of words per entry, currently 1. entry word 0 Left half: Address in file of SITE table entry for this host. Right half: Address in file of host name in ASCIZ.CONCLUSION: A host table capable of supporting the full host addressing of theARPANET and additional networks has been presented, along with a binaryfile format for efficient manipulation of this host table data. We are documenting this format in order to present it to theoutside world as a suggested replacement for the current host table.The advantage of our host table is that it has already been implementedand is in use at MIT and Stanford. We have established some conventionsMark Crispin [page 5]
NWG/RFC# 752 MRC 2-Jan-79 01:22 nnnnnA Universal Host Tablefor network names, as there are currently no network names assigned. Sothis RFC is also a request for some discussion about getting some namesassigned for the networks for the benefit of host tables. Anybody who is interested in importing our host table to their ownsystem should contact David Moon (MOON@MIT-MC) or me (MRC@SU-AI) formore information.ACKNOWLEDGEMENTS: Many people have been involved in the design and implementation ofthe current host table. They include, in no particular order, RichardStallman, David Moon, Ken Harrenstien, and Mark Crispin. I won't botherto list the contributions individually, since it's hard to determine whodid what and that sort of stuff is boring to read anyway.Mark Crispin [page 6]
NWG/RFC# 752 MRC 2-Jan-79 01:22 nnnnnA Universal Host Table APPENDIX The host table as of this writing is listed in this appendix.; ITS/SAIL Host Table; Last updated: MRC 1/2/79; Although the file <NETINFO>HOSTS.TXT at SRI-KL is the; official NIC host table, it is occasionally delayed in; reflecting actual network status, and does not include; colloquial-usage nicknames, operating system names,; machine types, or networks...; Hence this file, which is manually updated as necessary.; The "official" version is maintained as AI:SYSENG;HOSTS >; and copies are kept on SYSENG;HOSTS > on the other ITS; systems. SAIL's version is kept on HOSTS.TXT[NET,MRC].; Modifications should be made to the AI file and a note of; the change sent to Info-Hosts@AI and Info-Net@SAIL. If; you're going to modify it, you should warn MRC@SAIL and; SWG@DM, who normally maintain it, to avoid timing errors.; The easy way to compile the binary file and install it is; to run the batch command files:; :XFILE SYSENG;HOSTS XFILE at AI or; .BATCH /NOW @HOSTS.[NET,MRC] at SAIL.; If you want to do it the hard way, read those files.; The network table is in the format of one line entries looking like:; NET <name>,<network #>; sorted alphabetically by network name. All fields should be; in upper case. The fields are:; <name> official name of this network (whenever such; names get assigned; currently whatever sounds; good).;; The convention I have established is to; abbreviate "packet radio network" to "-PR".; "NET" is generally not part of the name unless; it is a proper name. The three networks; currently used by MIT and Stanford don't have; "NET" in them.Mark Crispin [page A-1]
NWG/RFC# 752 MRC 2-Jan-79 01:22 nnnnnA Universal Host Table; <network #> A single network number, in DECIMAL. These; numbers are assigned by Jon Postel.; The host table is in the format of one line entries looking like:; HOST <name>,<host #s>,<status>,<system>,<machine>,[<nicknames>]; sorted alphabetically by host name. All fields should be; in upper case. The fields are:; <name> official name of this site according to the; NIC.; <host #s> A single <host #> or a list of them in; brackets and separated by commas, with no; spaces in between.;; A <host #> is an OCTAL number, optionally; preceded by a network name (ARPA, CHAOS, DIAL); and a space. The default network name if none; is supplied is ARPA.;; Arpanet host numbers are represented in; BBN's backwards host slash IMP notation with; both numbers in DECIMAL. This gets compiled; into the 1.1 through 1.8 bits being the host; number, and the 2.1 through 3.7 bits being; the IMP number. For example, MIT-AI (host 2; on IMP 6 or 2/6) is compiled as 6002. Note; that the 1.9 and the 3.7 through 4.9 bits are; always zero! The HOSTS1 program compiles; into the old style 8 bit format (1.1-1.3 for; host number, 1.4-1.8 IMP number) whenever; possible; HOSTS2 and future programs only use; the new format.;; Chaosnet host numbers are in octal.;; Dialnet host "numbers" are really pointers to; an ASCII string. In the source, they are; represented as a 10-digit TelCo number.; <status> whether USER or SERVER. This is usually the; status "according to the NIC".; <system> operating system name (e.g., TENEX, ITS,; MULTICS, etc). Many elves actually have; other systems behind them; if possible, the; system behind the ELF is used rather than; the ELF. Also, TOPS-10 is used rather thanMark Crispin [page A-2]
