23/03/2003 - 2.60

   - sm_io was broken on sparc64
   - ntohq functions were not detected for big endian machines
   - c_config.sh broke on nfs mounts and pfsync
   
   All: thanks to Henning Brauer

26/02/2003 - 2.59

   - mbuf probe (Daniel Hartmeier; depends on 3.2)
   - example configuration is now installed in to symon/examples +
     better conflicts in port's PLIST (Christian Weisgerber)

24/01/2003 - 2.58

   Gustavo Chamone helped find a rare bug in symon/sm_io.c. strsep()
   would clobber stream information and make the first stream in the
   configuration file disappear.

   Daniel Hartmeier patched symon/sm_pf.c to deal with changes pf. His
   patch should also work for previous versions of pf.

10/01/2003 - 2.57

   Christian Weisgerber reported that netinet/ip_ipsp.h already defines
   htonq - fixed. Will Wainwright reported 1) a small bug in
   test_config.php - fixed, 2) that I left out some files
   (class_proc.inc and class_debug.inc) from the PLIST files.

29/12/2002 - 2.56

   Added proc and debug symon2web frontends. Debug has limited
   useability, you are better off defining one for yourself.

14/12/2002 - 

   Added the proc module. This can be used to retrieve accumulated
   information about processes with the same name. A proc(httpd)
   statement in symon.conf, for instance, will result in the reporting
   of the number of processes called "httpd" and the amounts of cpu and
   memory that they take.
  
   Added em device to c_smrrds.sh - thanks to Jung.  Fixed typo in
   SymuxClient.pm - thanks Tobias Gresch.  c_config.sh did not deal with
   type mfs devices - thanks Dom De Vitto.

29/11/2002 - 2.55

   Markus Friedl reported that unresolvable ip addresses cannot be used
   in the configuration file - fixed.

   Overhauled the networking code. Everything is now ip6 aware. This
   does mean that the ':' is no longer a keyword in the lexer;
   i.e. '<host>:<port>' statements should now be written as '<host>
   <port>' or '<host> port <port>'.

   Added the debug module. This can be used to retrieve debug0
   ... debug19 variables from the kernel.

08/11/2002 - 2.54

   Added a perl module that allows ppl to connect to symux and do
   something with the measurements as they come in. (I plan to drive an
   LCD using this, but it could also be used to get, say, daily
   bandwidth usage)
 
   Clients of symux would not sleep after they had read and relayed data
   symux gave to them. This could lead to one child eating up multiple
   'semaphore slots' and starvation in other clients - fixed.

25/10/2002 - 2.53

   Henning Brauer suggested a datadir statement for symux configuration
   - added.

   Henning also reported that c_smrrds.sh cannot create vlan10 and
   up. c_smrrds.sh now has a special case for pseudo-interfaces (bridge,
   enc, faith, gif, ppp, sppp, strip, tun, vlan)

   Nick Nauwelaerts helped improve dependency definitions in the port
   Makefile.

18/10/2002 - 2.52

   Julien Touche reported that symon/symux do not report initial cfg
   errors on the commandline - fixed.

   Reinhard Sammer, Julien and Henning Brauer all noticed that the php
   code needed globals - fixed. Passing by reference at call time
   resulted in php warnings - fixed.

   Henning thought it was nice to see a single machine at a time. Julien
   wanted clickable magnification for individual graphs. Both options
   can now be configured in datasources.inc.

   Resolved a bug reported by Vincent Kessler (who also provided the fix
   - cheers mate) in the rrdupdate call in symux - optind needs to be
   cleared ahead of the getopt call in rrdupdate.

   The Makefile.inc no longer overwrites CFLAGS. Configuration
   directories are now taken from the environment as expected by the
   openbsd ports system. (Thanks to Nick Nauwelaerts for pointing this
   out)

   Installation of symon now also generates a default symon.conf file if
   the system does not already have one.
   
   Someone at www.deadly.org pointed out that symon is no longer
   compatible with OpenBSD 3.0 - removed claim from the website.

   Added -f <file> switch to symon.

   The lexer started parsing from character position 1 instead of 0.

   symux would bomb out after a hup - fixed.

14/09/2002 - 2.51 

   Steve Shockley reported that the port Makefile did not install rrd
   tool. (Which is required for compilation of symux)

13/09/2002 - 2.5 - kvm gone, renamed mon to symon

   Rewrote io.c to obtain information via sysctl only. All kvm code is
   now gone.

   Renamed mon to symon, monmux to symux and mon2web to symon2web. I
   liked mon better, but that name is already taken.

   Cleaned up webpages to be XHTML 1.0.

10/09/2002 - 2.4

   Added some example pf graphs. This data is hard to plot, ideas are
   welcome. Added better port support.

09/09/2002 - Towards a better port makefile

   Reworked port Makefile. It now generates a number of packages that
   can be used to just install mon, monmux or mon2web. The KVM stuff has
   become a special flavor of the monitor package.

06/09/2002 - Cosmetics again

   monmux/c_monrrds.sh:
     - Added RRD_ARGS support. All created rrds have
       start=epoch. Incoming data from hosts may be from an earlier time
       than rrd creation now.

   mon2web/class_[io|if|mem|cpu].inc, index.php:
     - Rewrote argument representation of the graphs to be the same as
       how it is configured in the configuration files.

   mon2web/class_pf.inc, graph_pf.php:
     - Initial pf support.

01/09/2002 - Internal cosmetics - not released

   mon/mon.c: 
     - mon packetsize is still limited by size of struct monpacket in
       data.h:79. All other limits have been removed.

   lib/data.c mon/monnet.c monmux/muxnet.c:
     - header structure is now safely transported across the network.

   lib/data.c
     - added streamtypes b(yte) and s(hort) in preparation for new
       streams.

31/08/2002 - 2.3

    Makefiles, mon/mon.c: 
     - Environment variable KVM will enable the building of a setgid
       kmem version of the monitor. If this environment variable is not
       present, a non priviledged monitor will be built. (Note that all
       kvm dependant modules will fail during operation)

       After today's changes, only the io probe needs kvm.

    mon/if.c:
     - obtain ifdata as per h1kari's suggestion.

    mon/pf.c: 
     - global naming in sync with other probes
     - repeated initialisation would eat up fds

    Jan Sipke van der Veen
     - version number inconcistencies (main pkg/syslog)

    Daniel Hartmeier
     - shmat usage in monmux/share.c != 64 bit safe
     - some cpp macros missed precendence parenthesis


29/08/2002 - 2.2

    Merged contributions by Daniel Hartmeier:
     - cpu probe had a nasty va_arg bug that only showed up on
       big-endian machines.
    
29/08/2002 - 2.1

    Merged contributions by Daniel Hartmeier:
     - pf probe
     - changes to make mon compile on macppc and sparc64

28/08/2002 - released 2.0

    monitoring behaviour (mon) separated from storage/forwarding
    (monmux) and picture display (mon2web). Only mon has to run with
    kmem priviledges because of the if and io probes. Although the
    entire package was built with portability to other OpenBSD
    architectures in mind, it was never tested.

==== unreleased ====

25/07/2002 - rewrite stringptr functions in monmux to snprintf ones
           - package it for openbsd
           - added a crc32 algorithm in netmon and netmux
           - added DEBUG handling in Makefiles
           - removed a bug in monmux that made it reprocess already processed data.

22/06/2002 - added shared code, upgraded networking code

04/04/2002 - changed mon/monmux.conf format
	     written manual pages
             look at mon/cpu.c/percentages, give appropriate people credits.

01/04/2002 - changed all memsets into bzero
             all output messages have the same format now
             write pids in /var/run 
             SIGHUP = reload configuration

31/03/2002 - cleaned up source

             added error reporting routines. 

29/03/2002 - mon and monmux no use monpacket to communicate with each
             other. This format defines: version, lenght and crc of the traffic
             exchanged.

             mon no longer connects. monmux and mon can be started and stopped
             independently.

             monmux now checks if incoming traffic is allowed from a certain host.             

             added rrd write support to monmux

             made c_monrrds.sh determine what files to build from environment

             got mon2web up to date with mon1. changed interface layout to
             have output as a negative area - i'm not finished with this.

22/03/2002 - Added get/set preamble, still tinkering with those s(u)(n)pack
             functions. Added one that translates it into text.

06/01/2002 - Removed init and get functions from the monlib. (init functions
             were also required in non-mon applications, not like it is
             supposed to be :)

             Next step is to rewrite the get functions into using the pack
             function.

05/01/2002 - Wrote spack and sunpack; endianess agnostic values to bytestream
             (and back) functions. The packet format has almost been defined
             now.

24/11/2001 - Rewrote lib to KNF, OpCodes removed
03/11/2001 - Added datatypes and rewrote readconf to use SLISTs.
01/10/2001 - Mon configuration is read from a mon.conf. 
29/09/2001 - Lexer had trouble dealing with ip-addresses. Cleaned up the number	
             parsing code and removed a second comment reader.
