Also note that the file RFC2030.TXT is +David Mills's copyright and not the author's - it is just a copy of the RFC +that is available from so many Internet archives. + +RFC 1305 (Network Time Protocol - NTP) is an attempt to provide globally +consistent timestamps in an extremely hostile environment; it is fiendishly +complicated and an impressive piece of virtuosity. RFC 2030 (Simple Network +Time Protocol - SNTP) which supersedes RFC 1769 describes a subset of this that +will give excellent accuracy in most environments encountered in practice; it +uses only the obvious algorithms that have been used since time immemorial. + +WARNING: the text version of RFC 1305 is incomplete, and omits the tables that +are in the Postscript version. Unfortunately, these contain the only copy of +some critical information. + +The canonical NTP code for Unix is the xntp suite, and is as complicated as +would be expected from reading RFC 1305. While its code is moderately clean by +Unix and C standards, version 3-5.86 is over 80,000 lines and unavoidably +system-dependent. A worse problem is that it is so badly fouled up by its +configuration mechanism that ab initio porting could be several weeks' work, +even if the new system has all the necessary facilities and is bug free! + + +SNTP Servers - Some Little-Known Facts +-------------------------------------- + +RFC 2030 states that SNTP clients should be used only at the lowest level, +which is good practice. It then states that SNTP servers should be used only +at stratum 1 (i.e. top level), which is bizarre! A far saner use of them would +be for the very lowest level of server, exporting solely to local clients that +do not themselves act as servers to ANY system (e.g. on a Netware server, +exporting only to the PCs that it manages). + +If the NTP network were being run as a directed acyclic graph (i.e. using SNTP +rather than full NTP), with a diameter of D links and a maximum error per link +of E, the maximum synchronisation error would be D*E. Reasonable figures for D +and E are 5 and 0.1 seconds, so this would be adequate for most uses. Note +that the fact that the graph is acyclic is critical, which is one reason why +SNTP client/servers must NEVER be embedded WITHIN an NTP network. + +The other reason is that inserting SNTP client/servers at a low stratum (but +not the root) of an NTP network could easily break NTP! See RFC 1305 for why, +but don't expect the answer to stand out at you. It would be easy to extend +MSNTP to a full-function client/server application, thus making it into a true +alternative to xntp, but this incompatibility is why it MUST NOT be done. + +The above does not mean that the SNTP approach is unsatisfactory, but only that +it is incompatible with full NTP. The author would favour a complete SNTP +network using the SNTP approach, and the statistical error reduction used in +MSNTP, but it actually addresses a slightly different problem from that +addressed by NTP. TANSTAAFL. + +FINAL WARNING: do NOT use this program to serve NTP requests from outside the +systems that you manage. If you do this, and manage to break the time +synchronisation on other people's systems, you will be regarded very +unfavourably. Actually, this should be possible only if their NTP client is +completely broken, because MSNTP does its damnedest to declare its packets as +the lowest form of NTP timestamp. + + + +MSNTP and its Assumptions +------------------------- + +MSNTP is intended to be a straightforward SNTP daemon/utility that is easy to +build on any reasonable Unix platform (and most near-Unix ones), whether or not +it has ever been ported to them before. It is intended to answer the following +requirements, either by challenge and response or the less reliable broadcast +method: + + A simple command to run on Unix systems that will check the time + and optionally drift compared with a known, local and reliable NTP + time server. No privilege is required just to read the time and + estimate the drift. + + A client for Unix systems that will synchronise the time from a known, + local and reliable NTP time server. This is probably the most common + one, and the need that caused the program to be written. + + A server for Unix systems that are synchronised other than by NTP + methods and that need to synchronise other systems by NTP. This is + the classroom of PCs with a central server scenario. It is NOT + intended to work as a peer with true NTP servers, and won't. + + A simple method by which two or more Unix systems can keep themselves + synchronised using what is becoming a standard protocol. Yes, I know + that there are half-a-dozen other such methods. + + A base for building non-Unix SNTP clients. Some 3/4 of the code + (including all of the complicated algorithms and NTP packet handling) + should work, unchanged, on any system with an ANSI/ISO C compiler. + +There are full tracing facilities and a lot of paranoia in the code to check +for bad packets (more than in xntp) which may need relaxing in the light of +experience. Unfortunately, RFC 1305 does not include a precise description of +the data protocol, despite its length, and there are some internal +inconsistencies and differences between it and RFC 2030 and xntp3-5's +behaviour. + +WARNING: MSNTP has not been tested in conjunction with xntp broadcasts or xntp +clients, as the ability to do so was not available to the author. It is very +unlikely that it won't work, but you should check. Much of the paranoid code +is only partially tested, too, because it is dealing with cases that are very +hard to provoke. + +It assumes that the local network is tolerably secure and that any accessible +NTP or SNTP servers are trustworthy. It also makes no attempt to check that +it has been installed and is being used correctly (e.g. at an appropriate +priority) or that the changes it makes have the desired effect. When you first +use it, you should both run it in display mode and use the date command as a +cross-check. + +Furthermore, it does not attempt to solve all of the problems addressed by the +NTP protocol and you should NOT use it if any of those problems are likely to +cause you serious trouble. If they are, bite the bullet and implement xntp, or +buy a fancy time-server. + + +Building SNTP +------------- + +The contents of the distribution are: + +README - this file +Copyright - the copyright notice and conditions of use +Makefile - the makefile, with comments for several systems +header.h - the main header (almost entirely portable) +kludges.h - dirty kludges for difficult systems +internet.h - a very small header for internet.c and socket.c +main.c - most of the source (almost entirely portable) +unix.c - just for isatty, sleep and locking +internet.c - Internet host and service name lookup +socket.c - the Berkeley socket code +msntp.1 - the man page +RFC2030.TXT - the SNTPv4 specification + +All you SHOULD need to do is to uncomment the settings in file Makefile for +your system or to add new ones. But real life is not always so simple. As +POSIX does not yet define sub-second timers, Internet addressing facilities, +sockets etc., the code has to rely on the facilities described in the +ill-defined and non-standard 'X/Open' documents and the almost totally +unspecified 'BSD' extensions. + +Most hacks should be limited to the compiler options (e.g. setting flags like +_XOPEN_SOURCE), but perverse systems may need additions to kludges.h - please +report them to the author. See Makefile and kludges.h for documentation on +the standard hacks - there only 6, and most are only for obsolete systems. +But, generally, using the generic set of C options usually works with no +further ado. + + +Sick, Bizarre or non-Unix Systems +--------------------------------- + +A very few Unix systems and almost all non-Unix systems may need changes to the +code, such as: + + If the system doesn't have Berkeley sockets, you will need to replace + socket.c and possibly modify internet.h and internet.c. All of the + systems for which the author needs this have Berkeley sockets. + + NTP is supposedly an Internet protocol, but is not Internet specific. + For other types of network, you will need to replace internet.c and + probably modify internet.h. + + If the system doesn't have gettimeofday or settimeofday, you will + need to modify timing.c. If it doesn't have adjtime (e.g. HP-UX + on PA-RISC before 10.0), you can set -DADJTIME_MISSING and the code + will compile but the -a option will always give an error. + + If the system has totally broken signal handling, the program will + hang or crash if it can't reach its name server or responses time + out. You may be able to improve matters by hacking internet.c and + socket.c, but don't bet on it. + + If the the program won't be able to create files in /etc when + updating the clock, you can use another lock file or even set + -DLOCKFILE=NULL, which will disable the locking code entirely. On + systems that have it, using /var/run would be better than /etc. + + If the the program hangs when flushing outstanding packets (which + you can tell by setting -W), it may help to set -DNONBLOCK_BROKEN. + This seems needed only for obsolete systems, like Ultrix. + + If the system isn't Unix, even vaguely, you will probably need to + modify all of the above, and unix.c as well. + + Note that adjtime is commonly sick, but you don't need to change the + code - just use the -r option whan making large corrections (see below + for more details). + +Any changes needed to header.h or main.c are bugs. They may be bugs in the +code or in the compiler or libraries, but they are bugs. Please prod the +people responsible and tell the author, who may be able to bypass them cleanly +even if they aren't bugs in his code. The code also makes the following +assumptions, which would be quite hard to remove: + + 8-bit bytes. Strictly, neither ANSI/ISO C nor POSIX require these, + and there were some very early versions of Unix on systems with other + byte sizes. But, without a defined sub-byte facility in C, .... + + At least 32-bit ints. Well, actually, this wouldn't be too hard to + remove. But most Unix programs make this assumption, and I have very + little interest in the more rudimentary versions of MS-DOS etc. + + An ANSI/ISO C compiler. It didn't seem worth writing dual-language + code in 1996. Tough luck if you haven't got one. + + Tolerably efficient floating-point arithmetic, with at least 13 digits + (decimal), preferably 15, in the mantissa of doubles. Ditto. If you + want to port this to a toaster, please accept my insincerest sympathies + and don't bother me. + + A trustworthy local network. It does not check for DNS, Ethernet, + packet or other spoofing, and assumes that any accessible NTP or SNTP + servers are properly synchronised. + + +Warnings about Installation and Use +----------------------------------- + +Anyone attempting to fiddle with the clock on their system should already know +how to write system administration scripts, install daemons and so on. There +are a few warnings: + + Don't use the broadcast modes unless you really have to, as the + client-server modes are far more reliable. The broadcast modes were + implemented more for virtuosity (a.k.a. SNTP conformance) than use. + In particular, the error estimates are mere guesses, and may be low + or even very low. And even reading broadcasts needs privilege. + + The program is not intended to be installed setuid or setgid, and + doing so is asking for trouble. Its ownerships and access modes are + not important. It need not be run by root for merely displaying the + time (even in daemon mode). + + The program does not need to run at a high priority (low in Unix + terms!) even when being used to set the clock or as a server, except + when the '-r' option is used. However, doing so may improve its + accuracy. + + Unlike NTP, the SNTP protocol contains no protection against + client-server loops. If you set one up, your systems will spin + themselves off into a disconnected vortex of unreality! + + It will get very confused if another process changes the local time + while it is running. There is some locking code in unix.c to prevent + this program doing this to itself, but it will protect only against + some errors. However, the remaining failures should be harmless. + + Don't run it as a server unless you REALLY know what you are doing. + It should be used as a server only on a system that is properly + synchronised, by fair means or foul. If it isn't, you will simply + perpetrate misinformation. And remember that broadcasts are most + unpopular with overloaded administrators of overloaded networks. + + Watch out for multi-server broadcasts and systems with multiple ports + onto the same Ethernet; there is some code to protect against this, + but it is still easy to get confused. + + Don't put the lock file onto an automounted partition or delete it by + hand, unless you really want to start two daemons at the same time. + Both will probably fail horribly if you do this. + + The daemon save file is checked fairly carefully, but should be in a + reasonably safe directory, unless you want hackers to cause trouble. + /tmp is safe enough on most systems, but not all - /etc is better. + + +Installing and Using the Program +-------------------------------- + +Start by copying the executable and man page to where you want them. If you +want only to display the time and as a replacement for the rdate or date +commands, the installation is finished! + +You can use it as a simple unprivileged command to check the time, quite +independently of whether it is running as a time-updating daemon or server, or +whether you are running xntp. You can run it in daemon mode without updating +the clock, to check for drift, but it may fail if the clock is changed under +its feet. Unfortunately, you cannot listen to broadcasts without privilege. + +If it is used with the -a option to keep the time synchronised, it is best to +run it as one of root's cron jobs - for many systems, running it once a day +should be adequate, but it will depend on the reliability of the local clock. +The author runs it this way with -a and -x - see below. + +If it is used with the -r option to set the time (instead of the rdate or date +commands), it should be used interactively and either on a lightly loaded +system or at a high priority. You should then check the result by running it +in display mode. + +You are advised NOT to run it with the -r option in a cron job, though this is +not locked out. If you have to (for example under HP-UX before 10.0), be sure +to run it as the highest priority that will not cause other system problems and +set the maximum automatic change to as low a value as you can get away with. + +WARNING: adjtime is more than a bit sick on many systems, and will ignore large +corrections, usually without any form of hint that it has done so. It is often +(even usually) necessary to reset the clock to approximately the right time +using the -r option before using the -a and -x options to keep it correct. + +It can be started as a time-updating daemon with the -a and -x options (or -r +and -x if you must), and will perform some limited drift correction. In this +case, start it from any suitable system initialisation script and leave it +running. Note that it will stop if it thinks that the time difference or drift +has got out of control, and you will need to reset the time and restart it by +hand. + +In daemon mode, it will survive its time server or network disappearing for a +while, but will eventually fail, and will fail immediately if the network call +returns an unexpected error. If this is a problem, you can start it (say, +hourly or nightly) from cron, and it will fail if it is already running +(provided that you haven't disabled or deleted the lock file). + +If it is used as a server, it should be started from any suitable system +initialisation script, just like any other daemon. It must be started after +the networking, of course. To run it in both server modes, start one copy with +the -B option and one with the -S option. + + +Simple Examples of Use +---------------------- + +Many people use it solely to check the time of their system, especially as a +cross-check on xntpd. You do not need privilege and it will not cause trouble +to the local network, so you can use it on someone else's system! You can +specify one server or several. For example: + + msntp ntp.server.local ntp.server.neighbour + +You can use it to check how your system is drifting, but it isn't very good at +this if the system is drifting very badly (in which case use the previous +technique and dc) or if you are running xntp. You do not need privilege and it +will not cause trouble to the local network. For example: + + msntp -x 120 -f /tmp/msntp.state ntp.server.local + +More generally, it is used to synchronise the clock, in which case you DO need +root privilege. It can be used in many ways, but the author favours running it +in daemon mode, started from a cron job, which will restart after power cuts +with no attention, and send a mail message (if cron is configured to do that) +when it fails badly. For example, the author uses a root crontab entry on one +system of: + + 15 0 * * * /bin/nice --10 /usr/local/bin/msntp -a -x 480 ntp.server.local + +If you have a home computer, it can be set up to resynchronise each time you +dial up. For example, the author uses a /etc/ppp/ip-up.d/msntp file on his +home Linux system of: + + #!/bin/sh + sleep 60 + /bin/nice --10 /usr/local/sbin/msntp -r -P 60 ntp.server.local + +-a would be better, but adjtime is broken in Linux. + + +Debugging or Hacking the Program +-------------------------------- + +Almost everybody who does this is likely to need to modify only the system +interfaces. While they are messy, they are pretty simple and have a simple +specification. This is documented in comments in the source. This is +described above. + +The main program SHOULD need no attention, though it may need the odd tweak to +bypass compiler problems - please report these, if you encounter any. If +something looks odd while it is running, start by setting the -v option (lower +case), as for investigating network problems, and checking any diagnostics that +appear. Note that most of it can be checked in display mode without harming +your system. + +The client will sometimes give up, complaining about inconsistent timestamps or +similar. This can be caused by the server being rebooted and similar glitches +to the time - unfortunately, there is no reliable way to tell an ignorable +fluctuation from a server up the spout. If this happens annoyingly often, +the -V option may help tie down the problem. In actual use, it is simplest +just to restart the client in a cron job! + +If it needs more than this, then you will need to debug the source seriously. +Start by putting an icepack on your head and pouring yourself a large whisky! +While it is commented, it is not well commented, and much of the code interacts +in complex and horrible ways. This isn't so much because it lacks 'structure' +as because one part needs to make assumptions about the numerical properties of +another. + +The -W option (upper case) will print out a complete trace of everything it +does, and this should be enough to tie down the problem. It does distort the +timing a bit, but not usually too badly. However, wading through that amount +of gibberish (let alone looking at the source) is not a pleasant task. If you +are pretty sure that you have a bug, you may tell the author, and he may ask +for a copy of the output - but he will reply rudely if you send thousands of +lines of tracing to him by Email! + +Note that there are a fair number of circumstances where its error recovery +could be better, but is left as it is to keep the code simple. Most of these +should be pretty rare. + + +Changes in Version 1.2 +---------------------- + +The main change was the addition of the daemon mode for drift correction (i.e. +the -x option). The daemon code is complex and has a lot of special-casing for +strange circumstances, not all of which are testable in practice. + +A lot of the code was reordered while doing this. The output was slightly +different - considerably different with -V. + +The error estimation for broadcasts was modified, and should bear more relation +to reality. It remains a guess, as there is no way to get decent error error +estimates under such circumstances. + +The -B option is now in minutes, and has a different permissible range and +default value. + +The argument consistency checking for broadcasts was tightened up a bit, and a +few other internal checks added. These should not affect any reasonable +requirement. + +A couple of new functions were added to the portability base, but they don't +use any non-standard new facilities. However, the specification of the +functions has changed slightly. + + +Changes in Version 1.3 +---------------------- + +The main change was the addition of the restarting facility for daemon mode +(i.e. the -f option), which is pretty straightforward. + +There were also a lot of minor changes to the paranoia code in daemon mode, to +try to separate out the case of a demented server from network and other +'ignorable' problems. These are not entirely successful. + + +Changes in Version 1.4 and 1.5 +------------------------------ + +There turned out to be a couple of places where the author misunderstood the +specification of NTP, which affect only its use in server mode. The main +change is to use stratum 15 instead of stratum 0. + +And there were some more relaxations of the paranoia code, to allow for more +erratic servers, plus a kludge to improve restarting in daemon mode after a +period of down time has unsynchronised the clock. There is also an +incompatible change to the debugging options to add a new level - the old -V +option is now -W, and -V is an intermediate one for debugging daemon mode - but +they are both hacker's facilities, and not for normal use. + +Version 1.5 adds some very minor fixes. + + +Changes in Version 1.6 +---------------------- + +The first change is support for multiple server addresses - it uses these in a +round-robin fashion. This may be useful when you have access to several +servers, all of which are a bit iffy. This means that the restart file format +is incompatible with msntp 1.5. + +It has also been modified to reset itself automatically after detecting an +inconsistency in its server's timestamps, because the author got sick of the +failures. It writes a comment to syslog (uniquely) in such cases. + +The ability to query a daemon save file was added. + +Related to the above, the -E argument has been redefined to mean an error bound +on various internal times (which is what it had become, anyway) and a -P option +introduced to be what the -E argument was documented to be. + +The lock and save file handling have been changed to allow defaults to be set +at installation time, and to be overridable at run-time. To disable these +at either stage, simply set the file names to the null string. + +And there have been the usual changes for portability, as standards have been +modified and/or introduced. + + +Future Versions +--------------- + +There are unlikely to be any, except probably one to fix bugs in version 1.6. + +I attempted to put support for intermittent connexions (e.g. dial-up) into the +daemon mode, but doing so needs so much code reorganisation that it isn't worth +it. What needs doing for that is to separate the socket handling from the +timekeeping, so that they can be run asynchronously (either in separate +processes or threads), and to look up a network name and open a socket only +when prodded (and to close it immediately thereafter). So just running it +with the -r option is the current best solution. + +I also attempted to put support for the "Unix 2000" interfaces into the code. +Ha, ha. Not merely do very few systems define socklen_t (needed for IPv6 +support), but "Unix 2000" neither addresses the leap second problem nor even +provides an adjtime replacement! Some function like the latter is critical, +not so much because of the gradual change, but because of its atomicity; +without it, msntp really needs to be made non-interruptible, and that brings in +a ghastly number of system-dependencies. + +Realistically, it needs a complete rewrite before adding any more function. +And, worse, the Unix 'standards' need fixing, too. + + + +Miscellaneous +------------- + +Thanks are due to Douglas M. Wells of Connection Technologies for helping the +author with several IP-related conventions, to Sam Nelson of Stirling +University for testing it on some very strange systems, and to David Mills for +clarifying what the NTP specification really is. + +Thanks are also due to several other people with locating bugs, finding +appropriate options for the Makefile and passing on extension code and +suggestions.

Maclaren + Copyright (C) 1996, 1997, 2000 The University of Cambridge + +This is a complete SNTP implementation, which was easier to write than to port +xntp to a new version of Unix with any hope of maintaining it thereafter. It +supports the full SNTP (RFC 2030) client- and server-side challenge-response +and broadcast protocols. It should achieve nearly optimal accuracy with very +few transactions, provided only that a client has access to a trusted server +and that communications are not INVARIABLY slow. As this is the environment in +which 90-99% of all NTP systems are run .... + +The specification of this program is: + + msntp [ --help | -h | -? ] [ -v | -V | -W ] + [ -B [ period ] | -S | -q [ -f savefile ] | + [ { -r | -a } [ -P prompt ] [ -l lockfile ] ] + [ -c count ] [ -e minerr ][ -E maxerr ] + [ -d delay | -x [ separation ] [ -f savefile ] ] + [ -4 | -6 ] [ address(es) ] ] + + --help, -h and -? all print the syntax of the command. + + -v indicates that diagnostic messages should be written to standard error, +and -V requests more output for investigating apparently inconsistent +timestamps. -W requests very verbose debugging output, and will interfere with +the timing when writing to the terminal (because of line buffered output from +C); it is useful only when debugging the source. Note that the times produced +by -V and -W are the corrections needed, and not the error in the local clock. + + -B indicates that it should behave as a server, broadcasting time packets +at intervals of 'period' minutes. Acceptable values of 'period' are from 1 to +1440 (a day) and the default is 60. Naturally, this will work only if the +user has enough privilege. + + -S indicates that it should behave as a server, responding to time requests +from clients. Naturally, this will work only if the user has enough privilege. + + -q indicates that it will query a savefile that is being maintained by +it being run in daemon mode. + + The default is that it should behave as a client, and the following options +are then relevant: + + -r indicates that the system clock should be reset by 'settimeofday'. +Naturally, this will work only if the user has enough privilege. + + -a indicates that the system clock should be reset by 'adjtime'. +Naturally, this will work only if the user has enough privilege. + + -x indicates that the program should run as a daemon (i.e. forever), and +allow for clock drift. + + -4 or -6 force dns resolving to ipv4 or ipv6 addresses. + + The default is to write the current date and time to the standard output in +a format like '1996 Oct 15 20:17:25.123 + 4.567 +/- 0.089 secs', indicating the +estimated true (local) time and the error in the local clock. In daemon mode, +it will add drift information in a format like ' + 1.3 +/- 0.1 ppm', and +display this at roughly 'separation' intervals. + + 'minerr' is the maximum ignorable variation between the clocks. Acceptable +values are from 0.001 to 1, and the default is 0.1 if 'address' is specified +and 0.5 otherwise. + + 'maxerr' is the maximum value of various delays that are deemed acceptable. +Acceptable values are from 1 to 60, and the default is 5. It should sometimes +be increased if there are problems with the network, NTP server or system +clock, but take care. + + 'prompt' is the maximum clock change that will be made automatically. +Acceptable values are from 1 to 3600, and the default is 30. If the program is +being run interactively, larger values will cause a prompt. The value may also +be 'no', and the change will be made without prompting. + + 'count' is the maximum number of NTP packets to require. Acceptable values +are from 1 to 25 if 'address' is specified and '-x' is not, and from 5 to 25 +otherwise; the default is 5. If the maximum isn't enough, you need a better +consistency algorithm than this program uses. Don't increase it. + + 'delay' is a rough limit on the total running time in seconds. Acceptable +values are from 1 to 3600, and the default is 15 if 'address' is specified and +300 otherwise. + + 'separation' is the time to wait between calls to the server in minutes if +'address' is specified, and the minimum time between broadcast packets if not. +Acceptable values are from 1 to 1440 (a day), and the default is 300. + + 'lockfile' may be used in an update mode to ensure that there is only +one copy of msntp running at once. The default is installation-dependent, +but will usually be /etc/msntp.pid. + + 'savefile' may be used in daemon mode to store a record of previous +packets, which may speed up recalculating the drift after msntp has to be +restarted (e.g. because of network or server outages). The default is +installation-dependent, but will usually be /etc/msntp.state. Note that +there is no locking of this file, and using it twice may cause chaos. + + 'address' is the DNS name or IP number of a host to poll; if no name is +given, the program waits for broadcasts. Note that a single component numeric +address is not allowed. + +For sanity, it is also required that 'minerr' < 'maxerr' < 'delay' (if +listening for broadcasts, 'delay/count' and, in daemon mode, 'separation') and, +for sordid Unixish reasons, that 2*'count' < 'delay'. The last could be fixed, +but isn't worth it. Note that none of the above values are closely linked to +the limits described in the NTP protocol (RFC 1305). Do not increase the +compiled-in bounds excessively, or the code will fail. + +The algorithm used to decide whether to accept a correction is whether it would +seem to improve matters. Unlike the 'xntp' suite, little attempt is made to +handle really knotted scenarios, and diagnostics are written to standard error. +In non-daemon client mode, it is intended to be run as a command or in a 'cron' +job. Unlike 'ntpdate', its default mode is simply to display the clock error. + +It assumes that floating-point arithmetic is tolerably efficient, which is true +for even the cheapest personal computer nowadays. If, however, you want to +port this to a toaster, you may have problems! + +In its terminating modes, its return code is EXIT_SUCCESS if the operation was +completed successfully and EXIT_FAILURE otherwise. + +In server or daemon mode, it runs for ever and stops with a return code +EXIT_FAILURE only after a severe error. Commonly, two server processes will be +run, one with each of the -B and -S options. In daemon mode, it will fail if +the server is inaccessible for a long time or seriously sick, and will need +manual restarting. + + +WARNING: this program has reached its 'hack count' and needs restructuring, +badly.
