To Check Apache Version:

By default, Apache will send version and modules information like mod_php, mod_perl, mod_ssl in every HTTP header.

If you want to view Apache web server version and sofware of a remote server, follow this procedure.

# telnet example.com 80

Trying example.com...
Connected to example.com.
Escape character is ‘^]'.
HEAD / HTTP/1.0 <- after this press 2 times ENTER


HTTP/1.1 200 OK
Date: Sun, 07 Oct 2012 12:57:57 GMT
Server: Apache/2.2.21 (Unix) mod_ssl/2.2.21 OpenSSL/0.9.8e-fips-rhel5 mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 JRun/4.0

In the above example it is showing all the details about your web server and php this is not recommended for security reasons.We need to hide this information with the following procedure.


To Hide Apache Information:


To hide the information, add the following two apache directives in Apache configuration file, (httpd.conf or apache2.conf)

ServerTokens ProductOnly

ServerSignature Off

# /etc/init.d/httpd restart

Now the output for apache header looks like below

Server: Apache


To Hide PHP Version Details

Locate php.ini  loaded in the server.

Change the following option in php.ini

expose_php On

to

expose_php Off

# /etc/init.d/httpd restart


To Hide BIND Version


You can check the Bind version of a server by using the following command.

# dig +short @XXX.XXX.XXX.XXX -c CH -t txt version.bind
    "9.3.6-P1-RedHat-9.3.6-20.P1.el5_8.4"

To hide your version of bind, change the version value in named.conf as like the following.
You can give any string for the version.

options {

directory "/var/named";

version "We Just Hide It";

};

# dig +short @XXX.XXX.XXX.XXX -c CH -t txt version.bind
   "We Just Hide It"

Error Log of FTP access at the time of Block

libwrap refused connection to ftp (libwrap=pure-ftpd) from xx.xx.xx.xx
FAIL: ftp libwrap from=xx.xx.xx.xx


You can check the IP block as follows.

3. You can see a search bar there. You can search for the IP xx.xx.xx.xx  there.

4. You can select the IP by marking it and you can enter the button Remove to remove the IP block.

There is also an option for a whitelist the IP.

First of all check whether there is a cPanel script for installing ImageMagick available in the server or not. If yes,

# /scripts/installimagemagick

   -This will install ImageMagick automatically.

If not, follow the steps given below to install ImageMagick.

Install ImageMagick

1. # cd /usr/local/src/

2. # wget ftp://ftp.imagemagick.org/pub/ImageMagick/ImageMagick.tar.gz

3. # tar -xzvf ImageMagick.tar.gz
         -To download the ImageMagick setup compressed file and extract it.

4. # cd ImageMagick-*

    # ./configure

    # make
        -To configure and make ImageMagick from the source.

5. # make install
        -To install ImageMagick if the make process is successfully completed.

6. # make check

         -It will check the installation of ImageMagick. If  the installation completed successfully check will give a positive result.

7. # php -m | grep imagick

        -To check whether the  imagick module is loaded or not.

8. # /etc/init.d/httpd restart

Bind ImageMagick Into PHP

For your new ImageMagick installation to work with your web php scripts, you now need to bind it into PHP. To do this, just follow the steps below.

1. Login to WHM and navigate to the “Module Installers” option under “Software” in the left hand menu

2. On the following page, select the “Manage” link beside the PHP Pecl language option

3. Enter imagick into the “Install a PHP Pecl” field and then click the install button.

4. # /etc/init.d/httpd restart

Note 1:- Put a php info page and verify whether ' imagick ' is loaded or not.

<?php phpinfo(); ?>

Note 2:- You can install other php modules using Module Installers. The list of available php modules which can be installed using this cpanel feature is in the following url. There is no need to run easyapache to install those modules listed in this.
http://pecl.php.net/package-stats.php

Error:

Error: LogFile parameter is not defined in config / domain file

('/home/{user}/tmp/awstats/awstats.{domain.com}.conf' file, web server or permissions) may be wrong.

See AWStats documentation in 'docs' directory for informations on how to setup awstats.

Initial Checking:-

# ls -ld /home/{user}/tmp
    -Permission should be 700.

# cat /home/{user}/tmp/awstats/awstats.{domain.com}.conf
    -In some cases this file will be empty, it will cause the above error. This file must contain awstat configration.

Solution:

Usually the above error means one of the following ...

1. The /home/{user}/tmp doesn't have the correct permissions, you can fix this withthe following command.
     
 # chmod 700 /home/{user}/tmp
    -For one user

 # chmod 700 /home/*/tmp
    -For all users in the server.

2. The account has exceeded their disk quota and the awstats.domain.com.conf file cannot be created/updated.
      The stats will not run until the disk quota has been increased for the affected accounts.
You also might have to wait up to 24 hours for logs to run again, or you can force logs to run.

To run the webstats for one account:

 # /scripts/runweblogs {user}

To run the webstats for all accounts in the server.

 # /scripts/runlogsnow


 # cat /home/{user}/tmp/awstats/awstats.{domain.com}.conf
    -Check whether this file is emty or not. The file must contain the configration of awstat. If it is empty there will be some other issues.
