  •  Thanks to Ray Davis at Hewlett Packard for access to a hpux machine

  •  bug found in dns caching code which would handle invalid hostnames
	  improperly, causing core dumps
Changes for 0.78
	
  •  "config logging none" to not syslog stuff
	
  •  config noheartbeat to not send heartbeat packet
	
  •  moved most config.h options to config file
	
  •  added some memory leak debugging code
	
  •  multiple clients allowed at once!!! :)
	
  •  fixed a bug where multiple clients at once would cause a double
	  free() and kill the program
	
  •  periodic re-page option added, config pageinterval 33 where 33 is in
	  minutes
Changes for 0.77
	
  •  integrated some fixes from those great folks at ebone that keep me
	  on my toes with the code. (Steen.Linden@ebone.net)
	
  •  removed the passing of client_socket all about to use a structure
          that will later be expanded to do the multiple clients at once
	  stuff.

	  version on bootup for statistical purposes, never called again
	  no other data passed on.  You can #undef this in config.h
	
  •  added new config option for syslog to get out of config.h
	
  •  fixed single fd leak when loading config file :/
	
  •  fixed bug in snapshots of syslog not always logging stuff due to

	  more for it to be useful

  •  fixed some udp bugs
	
  •  various cleanups and runtime debugging started to be implemented
	  properly.. (sorta)
	
  •  syslog cleanup
	
  •  if syslog defined, it logs where client connections come from.
	  -- do we want rfc1413 (ident) support to be added?  blocking issues
	  with it.. etc..?
Changes for 0.76-beta3
	
  •  config numfailures support fixed
	
  •  curses client fixed (hopefully)

  •  pop3 config file options fixed
	
  •  overlapping internal variable problem fixed
	
  •  bug in non-blocking code that caused possible infinate loops and
	  slow checks to be performed, and possible bad data to be returned
	
  •  fix in some of the timer code
	
  •  TCP connection timed out sensing code fixed
Changes for 0.75.7
	
  •  several changes were done since the last version, not all were
	  documented.  They are listed here:
	
  •  imap support finished
	
  •  pop3 support finished

  •  redundant code elimiated
	
  •  filedescriptor leak found and plugged
	
  •  modularized the code a fair amount more in preparation for 
	  sending out checks in parallel
	
  •  testpop3 and testimap programs added to the suite, to test the
	  individual services.  There should be a sysmond -s option soon to
	  test them internally via command line before adding them to the
	  config file
	
  •  a few new parts of the data structure added for later expansion to
	  the parallel checking services.
Changes for 0.75.5
	
  •  fixed another little memory leak in the ping() function
	
  •  hacked on making all connections to block as little as possible
	  at all in this world without threads
	
  •  hacked on icmp.c a lot
	
  •  hacked on talktcp.c a lot
	
  •  made icmp.c not use signals to check for data anymore

	  Response
	
  •  made the "block" program take the argument of the hostname to
          check blocking on instead of it being hardcoded

Changes for 0.75.3
	
  •  fixed several blocking issues
	
  •  fixed a few more problems with client/server interaction
	
  •  fixed nntp checking so it won't mailbomb folks

Changes for 0.75.2
	
  •  more client fixes (of course -- the client sucks)
	
  •  fixed some inconsistencies in talking to sockets
	
  •  put in news server monitoring stuff.  Check sample config file
	  for an example
	
  •  added -d flag (no fork) to daemon (useful for debugging)
	
  •  added -v flag (prints version) to daemon and exits
	
  •  added -p flag (changes listening port number)
	
  •  added signal handling to properly exit if we've gotten something
	  ugly
	
  •  removed lotsa redundant code
Changes for 0.75.1
	
  •  little fixes in client
	
  •  now builds under Solaris x86 properly

Changes for 0.75 (YAY, the 
  • FINALLY RELEASED VERSION
  • )
	
  •  syswatch now forks() and leaves a daemon around unless -d (debug)
	  is specified on command line
	
  •  client is now in place and can request updates from the syswatch
	  daemon. (client hostname [portname]
Changes for 0.74beta5
	
  •  Fixed code so it would work without NICEINTERFACE defined
	
  •  Did some code cleanups, and more comments
	
  •  Fixed a few problems with portability
	
  •  Tested under NetBSD Alpha
	
  •  Started listening on port 1345 for client connections, but
	  don't do anything with them yet.
	
  •  mailing list created (syswatch@puck.nether.net)
Changes for 0.74beta3
	
  •  fixed bug with ping() with counting icmp echo responses
	  incorrectly if they came from another ping/monitor process
	  on the same host.  Reproducable using ping -f to another host
	  on an ethernet, then running the monitor program.. it would think
	  everything was down.
	
  •  Noticed code broken if NICEINTERFACE isn't defined
Changes for 0.74beta2
