Download and install Microsoft .Net Framework 3.5 SP1. And Windows Installer 4.5. before installing SQL Express 2008

Download Link : SQL Express 2008

Download Copssh from http://sourceforge.net/projects/sereds/files/Copssh

Install  Copssh

After the installation you have to assign user to access the serve

Select “Active a user”

Select the User and click next

Enter Password for above user

Click OK

Now you can access your Windows server using SSH.

Service name : OPENSSHSERVER

It is possible through a Port forwarding.

We have tested this in a ubuntu Host With Windows Xp guest OS. Here we will access Remote desktop of the XP ( Guest OS ) from the network.

IP : 192.168.0.1

When we try Remote desktop to 192.168.0.1 it will not connect to XP. Just drop the packet from Host OS ( Ubuntu ). We can do pot forwarding with following three commands.

|

VBoxManage setextradata “XP Test” “VBoxInternal/Devices/pcnet/0/LUN#0/Config/rdp/Protocol” TCP
VBoxManage setextradata “XP Test” “VBoxInternal/Devices/pcnet/0/LUN#0/Config/rdp/GuestPort” 3389
VBoxManage setextradata “XP Test” “VBoxInternal/Devices/pcnet/0/LUN#0/Config/rdp/HostPort” 3389

|

You have to change the following according to your need,
Windows Remote desktop Port : 3389
Host OS name : XP Test
Service : RDP

Now restart the Sun Virtual Box and Start the Guest OS

Port forwarding is enabled, when you Access Remote Desktop to 192.168.0.1 it Host OS will forward port 3389 to the Guest Os. and you can access XP Desktop.this port forwarding is happening on virtual box Layer

Tip 1:  Java Version

Typically, many performance optimizations are always being incorporated in newer releases of Java SE.  Whenever possible, it is a good idea to upgrade to  the latest version of Java SE Platform-to take advantage of these optimizations

To change Java version, edit the $GLASSFISH_HOME/config/asenv.conf.
Change the property called “AS_JAVA” to point to the desired Java version.

Tip 2:  Java Settings

By default, the GlassFish application server is configured to use the client VM (GlassFish application server is installed in developer profile). For better performance,  it is recommended to change this to “-server”.

Java Heap Size and other settings

-Xms and -Xmx

The size of the heap is determined by the Java options -Xmx (maximum) and -Xms (minimum).  While a larger heap can contain more objects and reduce the frequency of garbage collection, it may result in longer garbage collection times  especially for a full GC cycle. The optimum value for Xms and Xmx can be determined by the following points

initial and maximum heap sizes are

• Initial heap size of 1/64th of the physical memory, up to 1GB. (Note that the minimum initial heap size

is 32MB, since a server-class machine is defined to have at least 2GB of memory and 1/64th of 2GB is

32MB.)

• Maximum heap size of 1/4th of the physical memory, up to 1GB.

-XX:NewRatio

–XX:NewRatio=n 8 on server JVM

Ratio between the young and old generations. For example, if n is 3, then the ratio is 1:3 and the combined size of Eden and the survivor spaces is

one fourth of the total size of the young and old generations.

-XX:MaxPermSize

-XX:MaxPermSize=256m

-XX:+UseParallelGC

By default, the serial collector is the default garbage collector and is typically used for single processor machines and a small heap.  However, on server-class machines with more than one processor, parallel GC is the default. Ensure that parallel GC is being used (-XX:+UseParallelGC) for multithreaded machines which uses multiple threads for minor collections.  Major collections are the same as serial collector.

This  options can be set via Administration console:
1. Use the web browser URL:  http:<yourhostname>:4848 (the default
admin port)
2. Login with administrator user and password
3. Click on Application Server node on the left hand side, JVM settings
tab on the right hand side, then JVM options.
4. Edit the desired JVM option (or add New) in the textbox.
5. Click Save on the right hand side

Tip 3 – HTTP acceptor threads

HTTP acceptor threads accept new incoming connections and schedule new requests for the existing connections.  The default number of acceptor threads is one.  It is recommended to have 1 thread per 1-4 core, although experimentation may be necessary to find the optimal number.

This  options can be set via Administration console:

1. Login at the administration URL:  http://<yourhostname>:4848
2. Expand the node on the left hand side by clicking on Configuration –>
HTTP Service –> HTTP Listeners
3. Click on http-listener-1.
4. Edit the “Acceptor Threads” field under the Advanced setting.

Tip 4 – HTTP request processing threads

This pool of threads retrieve and process incoming HTTP requests.  The default
number of request processing threads is 5 but a starting rule of thumb is to tune
the number of HTTP request processing threads to the number of CPUs on the
SUT.  If you application is I/O bound, you can start with double the number of
CPUs.  Increase this number of threads until your throughput starts to decline.  At
the point when your throughput starts to suffer, the request processing threads
are starting to contend for CPU resources so some experimentation will be
necessary to find the sweet spot.

via Administration console:
1.  Login at the administration URL:  http://<yourhostname>:4848
2. Expand the node on the left hand side by clicking on Configuration –>
HTTP Service
3. Click on RequestProcessing Tab on right hand side.
4. Edit the text box beside Thread Count.
5. Click Save and restart.

Tip 5 -  Default-web.xml

The default-web.xml file defines features such as filters and security constraints that apply to all web applications.  The parameter, development=true, (the default value for developer profile) enables changes made to JSPTM – code to be  instantly visible to the clients. However, there is a cost associated with this. To avoid the cost of checking whether the JSP code  has been modified and hence its recompilation, the first parameter, development=false, can be used to set development to false since this scenario is unlikely in a production system.  This check affects application scalability when multiple users request the same JSP class. The second parameter, genStrAsCharArray=true, changes the way the JSPs are generated by generating char arrays for every static strings in the JSP class like for example, the HTML tags.  By default, the JSPcode  writer must call the toCharArray() on every String on every invocation of the JSPclass.

Settings in  default-web.xml.  ($GLASSFISH_HOME/domains/domain1/config/default-web.xml)
<init-param>
<param-name>development</param-name>
<param-value>false</param-value>
</init-param>
<init-param>
<param-name>genStrAsCharArray</param-name>
<param-value>true</param-value>
</init-param>

The more  configuration optimization can be done using the document from SUN you can download it here

Download – OptimizeGlassFishPerformance.pdf

Run following command to find the Process ID from port number

root@server:~ # fuser -n tcp 80

Now you can see the Process IDs associated with this service

80/tcp:               2584 15941 15943 15944 15945 16332 16333 16880 16881 16882 16899

Run the following command to find the service name from process ID

root@server:~ # ps -ef | grep 2584

root      2584     1  0 Apr01 ?        00:00:08 /usr/sbin/apache2 -k start

In these situations we have to find out which application is running on a particular port. Here is the step by step to find out this.

First identify the listening ports in your Server

Go to command prompt and type

Netstat –ano | find “0.0.0.0”

You can see the list here

Find out the corresponding Process ID from the line

Now open the task manager

Go to “View” and “Select Columns”

Put a Tick mark on “PID (Process identifier)”

Now you can see the application with process ID.

Here Port 80 is used by Apache ( httpd.exe )

Download KeyTool IUI :  Here

Create a keystore file

1. Select window’s task Create empty keystore

ie. if not visible, use in the menubar:

View | Select task | Create | Keystore

give password changeit that is the default password of glassfish keystore.jks, it will be easy if you give the same password.

1. Fill in the fields by clicking the respective icon buttons
   ==> once all required fields are filled, Action button (located at bottom) becomes enabled
2. Click Action button

Create a private key (keypair) entry, then save it in an existing keystore:

Trusted CA, private key (keypair) entry

ie. private key of type RSA.

This is done in 3 steps.

Step 1/3: create private key entry

1. Select task Create RSA private key entry

View | Select task | Create | Keystore’entry | RSA Private key with vers, with #1 cert

1. Fill in the fields
   ==> once all required fields are filled, Action button becomes enabled
2. Click Action button
   ==> A dialog shows up, containing the table of all available entries of the selected KeyStore
3. At the bottom of the dialog, enter new alias, enter password, confirm password

give alias name as s1as and password changeit this is the default alias name and password in glassfish, if you change the alias name and password the necessary changes has to be made in glassfish.

1. Click OK button

Step 2/3: export CSR

1. Select task Export certificate from private key entry as CSR file

View | Select task| Export | Certificate | CSR from private key entry

1. Fill in the fields
   ==> once all required fields are filled, Action button becomes enabled
2. Click Action button
   ==> A dialog shows up, containing the table of all available entries of the selected KeyStore
3. Select the alias pointing to the right private key (the one that was created in step 1/3), enter the respective password
4. Click OK button
   ==> This will generate a CSR file in PKCS#10 format. Submit this file to your CA (look for a CA that provides code signing certificate).

Step 3/3: import trusted certificate

Once your trusted certificate has been approved by the CA, you should receive it in PKCS#7 format (otherwise convert the one you get).  Copy the content(response conent which you receive in your mail) to a file and give extension .p7b (ex-:response.p7b)

Important

We also need to integrate intermediate certificate from the CA,otherwise some browsers (firefox 3.5) will show error during validation and say it is not a trusted certificate. We can download the intermediate from the CA’s site (for example verisign intermediate can be found in https://www.verisign.com/support/ssl-certificates-support/install-ssl-certificate.html). Copy the intermediate certificate and merge it with the response file, and then import to the keystore

How to

1. create file response+intermediate.p7b

2. Open response+intermediate.p7b file in vi, notepad or any other file editing tools

3. Copy the response file content send by your CA and paste it to the file (response+intermediate.p7b)

4. Copy the intermediate file content from CA site and paste it in the file (response+intermediate.p7b)

5. Now the response+intermediate.p7b file will be having two set of key’s, one is the response given the CA and the Intermediate taken from the CA website

6. Continue to the next step to import the response+intermediate.p7b file to keystore.jks

1. Select task Import CA certificate reply to private key entry

View | Select task| Import | Certificate | CA cert. replay to private key entry

1. Fill in the fields
   ==> once all required fields are filled, Action button becomes enabled
2. Click Action button
   ==> A dialog shows up, containing the table of all available entries of the selected KeyStore
3. Select the alias pointing to the right private key entry (the one that was created in step 1/3, and used in step 2/3), enter the respective password
4. Click OK button
   ==> This will import your trusted CA in the respective private key entry.

Now your keystore file is ready to deploy in glassfish. Copy the keystore file to server SDK/domains/domain1/config folder

restart the glassfish server, and take the url

copy, delete, change alias or/and password, …

1. Change keystore’s password,
2. Change secret/private key entry’s password,
3. Change entry’s alias,
4. Delete entry,
5. Copy entry,
6. View trusted certificate entry,
7. View private key entry’s certificates chain,
8. View secret key entry’s infos.

==> Open up KeyStore manager.

ie. from the menubar:

Tools | Keystore manager| [keystore-type] (JKS keystore)  keystore … (file name)

1, Install Debian lenny

Download link :  http://www.debian.org/releases/stable/

2, Install Following applications

Root@server # apt-get install openssh-server openssh-client apache2 libapache2-mod-php5 php5-cli php5-common php5-cgi  mysql-client mysql-common mysql-server php5-mysql php5-sqlite php5-gd phpmyadmin

3, Configure /etc/default/syslog-ng

Root@server # vi  /etc/default/syslog-ng

CONSOLE_LOG_LEVEL=1
case “x$KERNEL_RINGBUF_SIZE” in
x[0-9]*)
dmesg -s $KERNEL_RINGBUF_SIZE
;;
x)
;;
*)
echo “KERNEL_RINGBUF_SIZE is of unaccepted value.”
;;

4, Configure /etc/syslog-ng/syslog-ng.conf

Find following line  and remove the comment

Change  # udp();  to udp();
Change use_dns(no);    to  use_dns(yes);
add dns_cache(yes);

5,  Downloaded and extract PHP Syslog NG to /var/www

Source : http://sourceforge.net/projects/php-syslog-ng/

6, Move Log from /var/log/syslog to MySQL

Add following script to the file

Root@server # vi /etc/syslog-ng/syslog-ng.conf

destination d_mysql {
pipe(“/var/log/mysql.pipe”
template(“INSERT INTO logs
(host, facility, priority, level, tag, datetime, program, msg)
VALUES ( ‘$HOST’, ‘$FACILITY’, ‘$PRIORITY’, ‘$LEVEL’, ‘$TAG’, ‘$YEAR-$MONTH-$DAY $HOUR:$MIN:$SEC’,
‘$PROGRAM’, ‘$MSG’ );\n”) template-escape(yes));
};

log {
source(s_all);
destination(d_mysql);
};

7,  Create a  script to run in the start-up

root@Server # vi /etc/syslog-ng/syslog2mysql.sh

#!/bin/bash
if [ ! -e /var/log/mysql.pipe ]
then
mkfifo /var/log/mysql.pipe
fi
while [ -e /var/log/mysql.pipe ]
do
mysql -u root –password=YOUR_PASS syslog < /var/log/mysql.pipe >/dev/null
done

8, Give execute permission to /etc/syslog-ng/syslog2mysql.sh

root@Server# chmod +x  syslog2mysql.sh

9, Put this script to Startup

Create file /etc/rc2.d/S99syslog2mysql

And add following line in that file

/etc/syslog-ng/syslog2mysql.sh

Now run following command to make it as executable

root@Server# chmod +x /etc/rc2.d/S99syslog2mysql

10, Create a Database named SYSLOG

root@Server # mysql -uroot -p syslog /var/www/install/sql/dbsetup.sql
Give write access for file /var/www/config/config.php
root@Server # chmod 777 config/config.php

Now we have too configure the PHP syslog ng, for that access your server via web browser ( http://youripaddress/install/install.php ) and follow the steps. after the installation you can access your server via web ( http://youripaddress/ )
