Free photo viewer software for linux

php syslog viewer is a free web application written in PHP for viewing and searching system logs stored in a MySQL database.
Good system administrators review the logs from each system they administer. As the number of systems gets bigger, this becomes a more complex and time consuming task. Eventually the system administrator would like a way to combine the log messages from all of the systems into one central location, but that is not enough. Without a good search facility, finding the information the system administrator needs is like finding a needle in a haystack.
This is where php syslog viewer comes to the rescue. Using a few common Free Software tools (syslog-ng, stunnel, MySQL, apache, and php), php syslog viewer provides a total solution for centralized logging and log management. Client systems send their log files to a server which stores them in a database. php syslog viewer provides the system administrator with a view into that database. php syslog viewer also includes a tool for optimizing searches and archiving older data so that it takes up less room on the disk.
php syslog viewer is Free Software licensed under the GNU GPL (version 2 or later) as published by the Free Software Foundation.

Conntrack-Viewer is a perl script to view the masquerading connections with iptables, it uses /proc/net/ip_conntrack
With ipchains, it was extremely easy to view the masquerading connections, netstat -M or netstat --masquerade gave you the result right away.
But since iptables, if you try this you will get: "netstat: no support for `ip_masquerade on this system.". With iptables, the informations regarding the masquerading connections are accesible via /proc/net/ip_conntrack wich is extremely hard to read
This is why Conntrack-Viewer is so helpfull, it make those criptic results a lot more legible.
Enhancements:
- changed the service detection to use distant AND source port

tc-viewer provides the ability to watch current transfers that take place in HTB and HFSC traffic shaping classes on specified interface.

tc-viewer reads output from: tc -s class show dev iface, and analyzes (for each class) values in lines like this one :

Measured speeds may little vary from the real ones.

Mesh Viewer is an easy to use lightweight application to display triangular meshes from a variety of file formats (see 3D formats).
Mesh Viewer uses the OpenGL API to render the models. The program was born under the need for quickly displaying reconstructed triangulated meshes. The Mesh Viewer based on an idea and an early elementary implementation from Craig Robertson.
The current version was developed by Helmut Cantzler. Triangular meshes can be displayed texture mapped (optional with bilinear filtering), solid or as a skeleton (full or just the front lines).
The surface normals of the triangles can be displayed optionally. Features (from a different data file) like edges and points can be displayed into the mesh. Loaded models can be rotated, translated and scaled (all done with the mouse). The model is lighted by multiple light sources.
Viewpoints can be saved. Screenshots of the model can be taken (as BMP, JPEG, PNG and so on). The program is able to calculate the texture map for the 3D model (experimental!).
It can read:
- PMesh files (used at the Vision group of the University of Edinburgh)
- GTS files (from the Gnu Triangulation Library)
- Geomview files (only format "OFF")
- PLY files (only ASCII format)
- VRML 1 files (no texture mapping)
- VRML 2 files
- Feature file
- List file
File format descriptions:
The PMesh format begins optional with a header. The first header line consists of "#pmesh". The header ends with the first line not starting with a "#". The data starts with nv lines of the format "v float float float" for the vertices. Follows nf lines of the format "p 3 int int int" for the triangles. Each line contains the three indices of the vertices. The index of the vertices starts at one.
The GTS format is describe shortly. The first line contains three unsigned integers separated by spaces. The first integer is the number of vertices, nv, the second is the number of edges, ne and the third is the number of faces, nf. Follows nv lines containing the x, y and z coordinates of the vertices. Follows ne lines containing the two indices (starting from one) of the vertices of each edge. Follows nf lines containing the three ordered indices (also starting from one) of the edges of each face.
The Geomview formal starts with a header consisting of the format line "OFF" and a second line with three integer numbers. The first integer is the number of vertices, nv, the second is the number of polygons, np, and the third number is typically "0". Following are the nv lines of vertices (each consists of three floats). The other part of the file are np lines of polygons. The first number of each line stands for the size of the polygon. Mesh Viewer just reads polygons consisting of 2 or 3 vertices. Following are a number of indices of the vertices depending on the size of the polygon. The index of the vertices starts at zero.
VRML is only supported partly. The Mesh Viewer extracts only vertices and triangles from VRML files and ignores all other shapes. Shapes in VRML 2.0 are rotated, scaled and translated if necessary. The file name for JPEG texture and texture coordinates are read from VRML 2.0 files if existent.
The Feature file is used to store vertices and edges. A feature file can be loaded beside the mesh to display vertices or edges into the mesh. The first header line consists of "#list". The header ends with the first line not starting with a "#". The lines consists of either vertices or edges. A vertex line consists of the format "fv float float float". A edge line starts with "fe" followed by the x, y and z coordinates for the start and the end vertex.
The List file is only a text file listing n mesh files, which a loaded subsequently as different shapes into one mesh. Lists are useful for displaying a segmentation of a mesh. The first header line consists of "#list". The header ends with the first line not starting with a "#". The following n lines consists of the names for the mesh files (one per line).

frob 3D viewer project is a 3D object point/wireframe/polygon viewer - called frob3dv for lack of a better name.

I wrote this version mainly to learn c++. Also it was the first program I wrote after I got a PC (and put linux on it), but it has a long history. Many years ago I wrote a few stacks in Hypercard (on a Mac SE) for editing and displaying 3d shapes. I then ported it to modula-2 , using the free MacMETH compiler, then MOPS, a great free object-oriented programming language and application framework for the mac.

That is where it got most of its current class hierarchy. At that stage it was still only a wire-frame viewer. I then ported it to c++ for the macintosh using the Macintosh Programmers Workshop. When I wiped Windoze off my PC and put an operating system (linux) on it, I ported it to X and added the polygon drawing.
