5.1 – Installation Directories

This section identifies all standard files and directories of a normal IPS installation, as well as describes their contents and which platform they are designed for.

Path

Description

Platform

ips\

This is the IPS root directory. It consists of IPS's subdirectories and a couple of IPS's core files.

(directory)

ips\file_id.diz

Standard archive description file.

-

Small text file that redirects the reader to read the documentation\readme.txt and documentation\index.html files.

-

ips\binaries\

This directory contains all executables needed to run IPS and use all of its features. You should never run any of these programs directly.

(directory)

ips\binaries\ips2cgi.exe

IPS executable used to run CGI sessions.

OS/2

ips\binaries\ips2old.exe

IPS Server executable used before last update.

OS/2

ips\binaries\ips2srv.exe

IPS Server executable currently in use.

OS/2

ips\binaries\ips2upd.exe

Icon for IPS folders.

OS/2

ips\binaries\ico\ipsfldr2.ico

Icon for IPS folders.

OS/2

ips\config\

All IPS configuration files (CFs) are located in the directory tree beneath this directory. Each subdirectory will contain one site personality.

(directory)

ips\config\ips.cfg

The main IPS configuration file. This file is actually not a very interesting one. It isn't a configuration file for site personalities, but rather a config file for IPS internals.

-

ips\config\<site>\


(directory)

ips\config\<site>\<site>.cfg

A site personality configuration file (CF). Each one of these files defines a site personality's security, VFS tree and the services that run as part of that personality. IPS ships with one default site personality called "main", which is stored in ips\config\main, and defined in that directory's main.cfg file.

-

ips\documentation\

IPS documentation and default configuration directories are stored in this directory.

(directory)

ips\documentation\index.html

Main documentation entry point. If opened in a web browser, a convenient web-based interface to view IPS documentation can be used.

-

ips\documentation\*

All other directory entires are either documentation files or sub-directories containing default configuration directories.

-

ips\log\


(directory)

ips\log\ips2.log


OS/2

ips\log\ips32.log


Win32

ips\log\*.log

Service log files, whose files defined in the site personality CFs. Format is <site>-<service>.log!

-

ips\log\ips*.trc

Trace log files.

-

ips\log\<yyyymm>\


(directory)

ips\log\<yyyymm>\<datetime>.zip

The log file archive. All files in the parent directory are automatically archived into this zip file, whenever IPS is started up or restarted. The date and time are combined in a string of numbers to make up the filename. This makes it easy to locate a log that ends at a given point in time. The logs are easier to read since they're more compact than a single, monolithic log file. Format is <yyyymmdd>-<hhmmss>.zip!

-

ips\messages\ftp\

Multiple response message files and online help files for the FTPd service are placed in this directory.

(directory)

Please see ipsHookInterface.pas and ipsHookExample.pas for information about DllHooks.

5.5.2 – External Password Authentication

IPS can be configured to authentication the passwords for incoming connections from any external sources. This is implemented by developing a .dll with a special function exported which performs the password authentication.

The .dll must be named ipsauth.dll, and it must export the function ipsAuthenticate . In addition to this, the Password field in the user file must be set to <external>.

This function is called with two zero terminated string pointers using the default OS calling convention and should return a 32-bit integer value of 0 for successful validation or any other error value to deny password authentication.

5.5.3 – HTTP Plug-Ins

Please ask for information about this through the mailing list.
