install mod ssl on apache

May 19th, 2010

Aneesh

I am going to give you the steps to install mod_ssl on an Apache server by compiling the source.

Download the following packages

1. apache_1.3.14.tar.gz http://www.apache.org

2. openssl-0.9.6.tar.gz http://www.openssl.org

3. mod_ssl-2.7.1-1.3.14.tar.gz http://www.modssl.org

I have created a folder called /downloads/src and downloaded all packages here

Go to Apache source files and compile it as shown below

# ./configure –enable-module=so –enable-module=ssl –enable-module=mod_rewrite

Youc an add whatever module you needed

Now go to openssl folder and compile and install ( you can do this same by using yum or apt-get command)

To compile and install OpenSSL do the following commands

# sh config -fPIC
# make
# make install

At this time you can compile your PHP also. To do that run following commands

# ./configure –with-apache=../apache_1.3.41 –with-gd –with-zlib-dir –with-jpeg-dir –with-png-dir –with-freetype-dir –enable-gd-native-ttf –with-freetype-dir=/usr/lib/ –with-ttf –with-mysql=/usr/local/mysql –with-curl –disable-soap –with-openssl –with-xmlrpc –enable-ftp –with-xsl –with-mysqli=/usr/local/mysql/bin/mysql_config

# make

# make install

Compile Apache and install

Go to the apache Directory and runn following commands

# ./config.status
# make
# make certificate ( This step will be asked some inputs from you for your self signed SSL certificate)
# $ make install

Now you have installed the apache server with a self signed SSL certificate. Now it is the time to add the location of the .CRT file and .KEY file in your apache configuration file. From the above steps you can see the location of these files. Copy those paths.

Now open your httpd.conf file and add the following line

Listen 443

Now create a virtual directory which will listen the port 443

<VirtualHost XXX.XXX.XXX.XXX:443>
ServerName www.example.com
SSLEngine on
SSLCertificateFile /usr/local/apache/conf/ssl.crt/server.crt
SSLCertificateKeyFile /usr/local/apache/conf/ssl.key/server.key
</VirtualHost>

Now save the file and restart your Apache server

# apachectl stop

# apachectl startssl

Enjoy

skype automatically sends messages to all contacts

April 28th, 2010

Aneesh

Recently we have faced a Skye virus attack on a LAN. One of the users received a message

Do you think this is the definition of SEXY? I do.
http://www.xxxxxxxxxx.com/uploads/94603/NewPicture004.JPG.zip

Now the same message was started to send from this machine to all his skype contacts. Also sent email through email client. In a couple of minutes all systems were infected. We have done the following steps to fix it

1. Cleaned the hosts file
We have noticed that the hosts file located in c:\windows\sysetm32\drivers\etc\ was edited by the virus and it added many lines to the file at the very bottom. We scrolled down to the end and removed all unwanted entries. Remember this file is read only and you need to change the file attribute to save it.

2. Cleaned the System using ComboFix

Download this and run the file. Follow the instructions and complete the steps. In some cases you need to do with something on the Network Card. Go to Device manager and you will find two copies of the same network card. One with an Yellow color and other is normal. Now remove the Normal card and click on Scan for hardware changes and your card will be automatically installed. Note that you may also to set the IP address if you are using static IP address

3. complete System scan using a good Anti Virus

Use any good anti virus program to do a full system scan. I recommend Avast Antivirus and do a boot time scan with that
