JAVA Internet Proxy Server

Start Up of the PServer application

Windows Start Up

First you must start up your connection to your Internet Service Provider if not yet connected. This applies to all types of connections: DialUp, DSL, ISDN, T1, etc.
Second you must have created a configuration file called "pserver.data". You can copy the supplied sample "pserver.sampdata" and make any changes you may need. If you attempt to start up without specifying a configuration file or have an invalid or corrupted configuration file then the application will immediately terminate and post an error message.

From a "command screen" the PServer application can be started by changing your directory to pserver and then executing the pserver batch command:

 
             cd C:\pserver 
             pserver  pserver.data 

                         ,where pserver.data is the name of the configuration file.

The contents of the psetup.bat file look as follows:

 
 @ECHO OFF
 @ECHO Initiating the PServer Internet Proxy Server Application...
 DOSKEY
 SET PATHOLD=%PATH%
 SET CLASSPATHOLD=%CLASSPATH%
 SET mypathname=C:\pserver
 SET PATH=%mypathname%;%PATH%
 SET CLASSPATH=%mypathname%\NetRexxR.jar;%mypathname%\pserver.jar;%CLASSPATH%
 java -ms64M -cp %CLASSPATH%  PServer %1
 SET PATH=%PATHOLD%
 SET CLASSPATH=%CLASSPATHOLD%
 @ECHO OFF

Linux Start Up

You must have created a configuration file called "pserver.data". You can copy the supplied sample "pserver.sampdata" and make any changes you may need. If you attempt to start up without specifying a configuration file or have an invalid or corrupted configuration file then the application will immediately terminate and post an error message.

Now acquire "root" access and change directory to /usr/local/pserver/

Type

 
             pserver  pserver.data 

                         ,where pserver.data is the name of the configuration file.

The contents of the pserver script file look as follows:

 
#!/bin/bash
#
 echo "...Executing PServer Internet Proxy Server..."
 javalib="j2sdk1.4.2"
 myclasspath=/usr/local/pserver/NetRexxR.jar:/usr/java/$javalib/jre/lib/rt.jar:/usr/local/pserver/pserver.jar
 echo "JAVA Lib is "$javalib
 echo "CLASSPATH is "$myclasspath
 echo "PATH is "$PATH
 echo "Parameters "$1 $2 $3 $4  

 java -ms64M -cp $myclasspath PServer $1 $2 $3 $4  

 echo "...PServer Internet Proxy Server has terminated..."
 exit 0

Note that the configuration file "pserver.data" is taken as an argument (%1). The JAVA virtual machine allocates 64 Megabytes of storage (java -ms64M ...). The CLASSPATH is set to access both supplied JAR files containing executable code.

Upon invocation of psetup, the main graphical window will open and cause the PServer program to engage.

Go to the "Daemons" panel to check the port listening assignments. Change if necessary, should you need to select a different port assignment or disable a protocol.

Go to the "Event Logging" panel and select your file and console logging if desired. Also, you may set the tracing levels to be recorded in the log file.

Next, go to the "Tuning" panel to check your multitasking levels and buffer sizes. The defaults are displayed. You may want to change these in the future to accommodate a higher level of traffic and number of client computers in your network.

Now use the "Service" pulldown and choose "Start". The proxy will initialize and is now ready for work.
