Free eye of horus software for linux

The Eye Of Horus is a monitoring and alerting tool for computers. Its mainly useful for monitoring network services (eg, HTTP or SMTP servers) and the internal status of Unix servers (eg, load, disk usage, process counts).

In that respect, its a lot like Nagios, but in my opinion its better. It lacks a few features Nagios has, but it is a very simple architecture to which they can easily be added.

Its a flexible thing made from independent modules with well-defined interfaces, making it easy to customise and extend, but out of the box itll monitor your servers and produce a nice HTML summary of their status - OK, the looks need a bit of work, but that will come soon, and it can optionally integrate with the excellent (and I mean excellent) RRDTool to store logs of statistics (response times, number of packages with known security holes, etc) - and link from the status page to nice graphs of the historical behaviour of these statistics.

HOW IT WORKS

The core of the system is horus-check.py, a Python script which reads a configuration file (specified on the command line). The configuration file specifies a list of services - either network services, in which case the host to run the check from and the host to run the check at are specified, or local services, in which case only the host to run the check from need be specified. In either case, if the host to run the check from is not specified, then it defaults to the local host.

The service types reference definitions in a file which is referenced from the configuration file. In the service definitions file, a shell command to check the service is given; this command must output service status in a defined format, as a single-line YAML list. The list must contain, at least, a single-word status (OK, WARNING, FAILURE, or UNKNOWN), then optionally numeric statistics, then optionally a status message. For example:

[OK]
[UNKNOWN]
[OK, { load: 0.5, users: 3 }]
[WARNING, { load: 3, users: 30 }]
[FAILURE, { load: 95, users: 300 }]
[UNKNOWN, { }, Could not find AWK executable]

When a check is to be performed from a remote host, Horus opens an ssh connection to that host. It is assumed that the user horus is run as will have an ssh key set up to enable it to ssh to all such hosts without requiring a password.

Having performed the checks, horus-check.py then:

Reads in the status database named in the configuration file
Updates the status database with the new status of hosts
Computes an overall system status (the worst non-unknown status of any checked service)
Examines the service dependencies, and marks any service whose state is no worse than might be expected (eg, no worse than the worst state of a service it depends upon) are automatically marked as quiet
Computes a list of differences between the old and new status (services added, services removed, services whose status has improved, services whose status has worsened)
If there are any differences, invokes a notification script (named in the configuration file) with them, along with the overall status
Invokes a logging script (named in the configuration file) with the new value of every statistic reported by the service checks; I will soon provide a sample logging script that uses RRDTool to generate nice graphs.

The status database (which is written in YAML, so easily accessible to user scripts) can then be used to generate HTML status report (see status.cgi).

Hammer of Thyrion is a port of Ravens Hexen2 source code and is based on the original Linux Hexen II project, Anvil of Thyrion.

HoT includes many bugfixes, improved sound and video modes, opengl improvements and documentation among many others.

Whats New in This Release:

General:
--------
- The engine version is now at 1.19 for Hexen II and 0.19 for HexenWorld.
- Added support for 64 bit architectures: The crashes on amd64 are fixed.
- Added support for protocol 18: Hammer of Thyrion is now fully network-
compatible with Ravens 1.11 windows version, as it has been with other
Hexen II ports.
- The net compatibility works both ways: When H.o.T is run as a client,
it can connect to Raven-1.11 servers and can play just fine. On the
other hand, if a 1.11 client wants to connect to a H.o.T. server, the
server must be started with "-protocol 18" command line argument.
- You can also load and play games saved with the 1.11 windows version and
can playback the demos recorded with the 1.11 version.
- Fixed and improved parsing of puzzles.txt: This fixes the bug where the
names used to be listed as Unknown in the puzzle pieces inventory display
(you can access the puzzle pieces inventory display using a key bound to
the +showdm command, the default is q).
- Updated the loading of strings.txt, infolist.txt and puzzles.txt.
- Updates to SDL input code. Added the Shift-Escape key combination as a
new means for opening the in-game console.
- Fixed many printf format string errors.
- Revised pak data checking.
- Added experimental support for using unpatched, off-the-cdrom 1.03 version
pak files as a compile time option. Disabled by default.
- Several cvar tweaks.
- Made the load and connect commands to get rid of the menu or the console.
- Fixed multiplayer episode selection in the menu system.
- Updates to zone memory usage: a 256 KB secondary zone for static textures
(sec_zone) is now initialized, which is especially useful for the software
renderer and have its merits for the opengl version, too.
- Revised several unsafe LoadStackFile and LoadBufFile usage.
- Removed the useless net_vcr facility.
- Tweaked the init sequence.
- Changed the remnants of malloc usage into hunk or zone allocations.
- Mac OS X: Ensured that the basedir always stays the same (fix was added
in 1.4.1-rev1).

Gameplay:
---------
- The gamecode is now at version 1.19.
- Origin fixes for tomed fires of vorpal sword and purifier: paladin used
to fire them always from the non-crouched eye position, and it was even
the worst when he was looking up (and down). You wont be shooting your
back again when standing just in front of a wall and fire your tomed
purifier to the sky, from now on ;)
- Fixed an obscure bug where the assasin with her 4th weapon uses the tome
of power and cant fire it (gamecode version 1.16a, the fix was added in
1.4.1-rev1).

Console:
--------
- Added prefix matching support to the maplist command.
- A duplicate name detection bug in the maplist command was fixed.
- Updated and sanitized the command lister procedures.
- Added a -developer command line argument which sets the developer cvar to
1 during the init phase (ie. before the config is read).
- Consolidated all Con_Printf and Sys_Printf family of procedures into a
single flag based procedure. Added macros for compatibility with the old
api.
- Revised the logging system, made all Con_Printf and Sys_Printf output to
be written into the logs from the start. Added a -devlog command line
switch to enable logging of developer message even when the developer cvar
isnt set.

Server:
-------
- Fixed the mission packs doWhiteFlash server message: it used to affect the
local client only. Naturally, the recorded demos didnt carry the message
and the flash didnt appear, either. It works properly now.
- Made the Hexen II dedicated server to exec not hexen.rc or config.cfg, but
server.cfg if available. As an alternative, any config file can be execed
when starting the server, such as: "h2ded +exec myconfig.cfg"
- Hexen II dedicated server now starts the demo1 map, if the server is still
not active when initialization is complete.
- Fixed net driver checks in Hexen II dedicated server: It was broken in the
1.4.1 release and works properly now.

Video:
------
- Added apply changes and reset changes items to the video options menu.

Software Renderer:
------------------
- Added ability to load external wal texture files instead of internal pixel
data of the brush model (depends on the new r_texture_external cvar).

OpenGL Renderer:
----------------
- Some speed-ups in the alias model drawing.
- Fixed RGBA lighting.
- Fixed bug that the array size for playertextures must be MAX_CLIENTS, but
was hardcoded as 16.
- Added ability to load external wal texture files instead of internal pixel
data of the brush model (depends on the new r_texture_external cvar).

Sound:
------
- Added external music file support via SDL_mixer as an extra patch.

CDAudio:
--------
- Updated the volume setting procedures.

HexenWorld:
-----------
- OpenGL: Fixed bug that netgraphtexture was not reset during reinitializa-
tion of the draw subsystem (used to affect the packet loss status graph by
r_netgraph).
- OpenGL: Fixed bug that dynamic lights had a problem with RGBA lightmaps
(such as torches didnt illuminate) but luminance mode was fine. Lightmaps
in RGBA mode are working now.
- OpenGL: Added colored dynamic lights and extra dynamic lights (stuff copied
over from hexen2). The gl_colored_dynamic_lights and gl_extra_dynamic_lights
cvars and their menu entries are functional now.

Launcher:
----------
- Added integrated ability to patch the pak files.
- The launcher now scans the installation directory against known game versions
for pak file health, and pops up the patch window with a short report if it
finds something bad. It now disables the mission pack or hexenworld options
according to the results it took from the installation scanning.
- Many clean-ups. Incremented the version number to 1.0.0.

Utilities:
----------
- Added the bsp2wal tool which extracts all texture data into hwal files.
- Added the lmp2pcx tool which converts hexen2 texture data into pcx and tga.
- Fixed the broken project path decision in qbsp. it doesnt scan for a maps
directory anymore.
- Added a findfirst/findnext implementation to the common library.
- Several fixes in dcc.

Other:
----------------------
- Imported the latest xdelta-1.1 sources into the tree.
- Started a large scale attempt at improving const-correctness.
- Updated inline commentaries.
- A lot of code clean-up all over the tree.

This is a play-thing, requested by a few people on the forum, and definitely not for the average user. In other words, Linux commandline nerds only! OneBone does not have any X GUI applications.

It does have Elinks web browser, Ytree file manager and MP text editor. The Lucent and SmartLink modem drivers are included. There are lots of text-mode applications out there and a very interesting flavour of Puppy could be created, based on this starting point.

Puppy Linux is an evolutionary operating system, based on GNU Linux. Whats different here is that Puppy is extraordinarily small, yet quite full featured. Puppy Linux can boot into a 64MB ramdisk, and thats it, the whole caboodle runs in RAM.

Unlike live CD distributions that have to keep pulling stuff off the CD, Puppy in its entirety loads into RAM. This means that all applications start in the blink of an eye and respond to user input instantly.

Puppy Linux has the ability to boot off a flash card or any USB memory device (flash-Puppy), CDROM (live-Puppy), Zip disk or LS/120/240 Superdisk (zippy-Puppy), floppy disks (floppy-Puppy), internal hard drive (hard-Puppy).

pretrace is a preload library that allows specified (dynamically linked) applications to always be executed under a debugging environment.

pretrace library allows you to specify the percentage of invocations which will be traced, to help you "keep an eye" on applications without bringing the machine to its knees.

To start using pretrace, add libpretrace.so to your /etc/ld.so.preload.

root# echo /lib/libpretrace.so >> /etc/ld.so.preload

You can now specify applications to trace in /etc/pretrace.conf, the format is one application per line, if you would like to specify a debugger append a colon, then the full path to the debugger and any arguments you would like to pass. If you do not specify a debugger, you get the default, strace, which saves the output to .logfile in the current working directory.

An optional number can be appended in the format %N, eg %50, to specify what percentage of invocations should be traced.

# this is a comment
/full/path/to/application[%percent][:/full/path/to/debugger [arg1 arg2 ...]]

An example pretrace.conf is provided with this distribution.

After modifying pretrace.conf, you should execute ptgenmap to generate a new map file, this is used to quickly parse the configuration file with minimal impact on initialisation time.

libpretrace is designed as a debugging utility for developers and auditors, and should not be used in a production environment.
