Limit receiving message size using filter
For limiting a receiving message size on cPanel servers we can
make use of account level exim filters .
You will need to edit them manually as there is no option for
limiting size of the message through cPanel interface.
Following filter script has been tested and it worked
successfully.
Edit file /etc/vfilters/yourdomain.com and paste the following
rule :
Code:
# Exim filter
#Rule1
if
$message_body_size is above 3M then
mail
to $sender_address
from bounce@yourdomain.com
subject “RE: $header_subject:”
fail “Your message was over 3MB size limit and so it was not delivered.”
seen finish
endifSave changes and exit.
# Exim filter
#Rule1
if
$message_body_size is above 3M then
to $sender_address
from bounce@yourdomain.com
subject “RE: $header_subject:”
fail “Your message was over 3MB size limit and so it was not delivered.”
seen finish
endifSave changes and exit.
Now edit /home/username/.cpanel/filter.yaml and paste the
following rule :
Code:
—
filter:
-
actions:
-
action: fail
dest: Your message was over 3MB size limit and so it was not delivered.
filtername: Rule1
rules:
-
match: is
opt: or
part: “$message_body_size:”
val: 3MSave changes and exit.
—
filter:
-
actions:
-
action: fail
dest: Your message was over 3MB size limit and so it was not delivered.
filtername: Rule1
rules:
-
match: is
opt: or
part: “$message_body_size:”
val: 3MSave changes and exit.
You can now send a test email of size more than the specified
limit in the filter , here it is 3M and then send it to the emailuser set under
yourdomain.com (example : receiver@yourdomain.com).
The exim logs will show the following message :
Code:
2010-07-20 18:00:00 1ObGml-0007Q6-BJ ** receiver@yourdomain.com R=central_filter: Your message was over 3MB size limit and so it was not delivered.And the sender will receive the mail delivery failed message :

Ntsysv : Linux /
Unix Command
NAME
ntsysv – simple interface for configuring runlevels
SYNOPSIS
SYNOPSIS
ntsysv [--back] [--level ]
DESCRIPTION
DESCRIPTION
ntsysv is a simple interface for configuring runlevel services
which are also configurable through chkconfig. By default, it configures the
current runlevel. If the user would like to configure other runlevels, those levels
can be specified on the command line by listing the levels after –levels,
without any spaces. For example, the option –levels 016 edits runlevels 0, 1,
and 6.
A service is considered to be started in the runlevel set if it is started in any of the runlevels which are being edited.
A service is considered to be started in the runlevel set if it is started in any of the runlevels which are being edited.
The ntsysv window normally contains a Cancel button. If –back is
specified, a Back button appears instead.
RETURN CODES
ntsysv returns 0 on success, 2 on error, and 1 if the user
cancelled (or backed out of) the program.

How To Find Out If Harddisk Failing
There are a few ways to check for signs of drive failure on a
CentOS/Cpanel server. The easiest is as root user run the command
“/scripts/smartcheck”. This will check the disk for errors using Cpanel’s built
in script if there are no errors returned here no further investigation is
required. If an error is returned the command to investigate further is
“smartctl -a /dev/[disk]” were [disk] is the disk with the reported error. If
the server is using a RAID array the first command listed will not work. The
only way to check for errors on a RAID array server is the smartctl command but
the syntax is different. The command for RAID array servers is “smartctl -a
/dev/twa0 -d 3ware,[X]” or “smartctl -a /dev/twe0 -d 3ware,[X]” were [X] is a
number 0-3. The number represents the disk in order from p0 to p3.
The smartctl command presents a lot of information and the
values it shows can vary depending on the drive. For more information on the
SMART values wikipedia has a lot of good information about each one.

How To Completely Clean Your Hacked WordPress Installation
Note : Here we are reinstalling the wordpress.
1. Backup The Site And The Database.
Even a hacked copy of your blog still probably contains valuable
information and files. You don’t want to lose this data if something goes wrong
with the cleanup process. Worst case scenario you can just restore things back
to their hacked state and start over.
2. Make A Copy Of Any Uploaded Files, Such As Images,
That Are Referenced.
Images are generally exempt from posing a security risk, and
ones that you uploaded yourself (as opposed to ones included with a theme, for
instance) will be harder to track down and replace after things are fixed
again. Therefore it is usually a good idea to grab a copy of all the images in
your upload folder so as to avoid broken images in posts later. If you have any
non-image files that could potentially have been compromised, such as zip
files, plugins, or php scripts that you were offering people, then it is a good
idea to grab fresh copies of those from the original source.
3. Download A Fresh Version Of WP, All Of The Plugins
You Need, And A Clean Template.
Using the WordPress automatic upgrade
plugin does make it easier to upgrade every time a new version comes out.
However, it only replaces WordPress specific files, and does not delete
obsolete ones. It also leaves your current themes and plugins in place, as is.
This means that if used to upgrade a blog that has already been compromised, it
can very well leave the attackers a way back in. It is best to start over from
scratch as far as the files portion of your installation goes. Note that if you
use the EasyWP
WordPress Installer script
that I wrote it saves you from having to download, unzip, and then upload all
of the core WordPress files, although you will still need to grab fresh copies
of the themes and plugins that you want to use.
4. Delete All Of The Files And Folders In The WP
Directory, Either Through FTP (Slower) Or Through CPanel’s File Manager
(Faster).
Now that you have fresh copies of all the files you need, and
copied all of your uploaded images, completely delete the entire directory
structure your blog is in. This is the only surefire way to completely remove
all possibly infected files. You can do this through FTP, but due to the way
that FTP handles folder deletion (ie. it walks the directory structure, stores
each and every file name that needs to be deleted, and then sends a delete
command for each one), this can be slow and in some instances cause you to get
disconnected due to flooding the server with FTP commands. If available it is
much faster to do this through either cPanel’s File Manager, or via command
line if you happen to have shell access.
5. Re-Upload The New Fresh Copies You Just Grabbed.
This step should be self explanatory,
but I would like to mention that if your FTP client supports it (I use FileZilla, which does) and your
host allows it, then increasing the number of simultaneous connections you use
to upload can greatly reduce your overall transfer time, especially on servers
or ISP’s where latency is more of an issue than bandwidth. In FileZilla this
setting is found by going to “Edit -> Settings -> File transfer settings”:
Also, if not using the EasyWP
WordPress Installer script,
don’t forget to edit and rename your wp-config.php file (when freshly unzipped
this is named wp-config-sample.php).
6. Run The Database Upgrade (Point Your Browser At
/Wp-Admin/Upgrade.Php).
This will make any necessary changes to your database structure
to support the newest version of WordPress.
7. Immediately Change Your Admin Password.
If you have more than one admin
(meaning any user with editing capabilities), and cannot get the others to
change their passwords right then, I would change their user levels until they
can change their passwords as well. If there is anyone in your user list that
has editing capabilities, and you do not recognize them, it’s probably best to
just delete them altogether. If changing passwords is something you hate doing,
then maybe my new memorable password generator can make that a little less stressful
for you. 
8. Go Through The Posts And Repair Any Damage In The
Posts Themselves.
Delete any links or iframes that were inserted, and restore any
lost content. Google and Yahoo’s caches are often a good source of what used to
be there if anything got overwritten. The following query run against the
database can help you isolate which posts you want to look at:
SELECT * FROM wp_posts WHERE post_content LIKE '%<iframe%'
UNION
SELECT * FROM wp_posts WHERE post_content LIKE '%<noscript%'
UNION
SELECT * FROM wp_posts WHERE post_content LIKE '%display:%'
If you did not change the default prefix for WordPress tables,
than you can copy and paste that directly into a query window and run it, and
it should pull up any posts that have been modified to hide content using any
of the methods I have come across so far (iframes, noscript tags, and
display:none style attributes). To get to a query window in cPanel, you would
click on the MySQL® Databases icon, scroll to the bottom of the page, and then
click on phpMyAdmin. Once the new window or tab opens, you would click on the
database in the left hand side that your blog was in, and then in the right
side at the top click on the SQL tab. Then just paste the query into the large
text area and hit the Go button.
Note, however, that there may be other types of injected content
that I haven’t seen yet, and that a manual inspection looking for the types of
patterns that first alerted you to the fact that your blog was hacked is always
a good idea.
UPDATE: 9. If You Are Having Issues Cleaning The
Installation Yourself
When I wrote this post back in 2008 I
intended it to be a do it yourself guide for the non-techie. However, I do
realize that some people would still rather a professional programmer perform
many of the steps I outlined here. If anyone has had their WordPress
installation hacked, and either is uncomfortable attempting to clean it on
their own, or has tried to do so with no success, I am available on a case by
case basis. Most cleanings can be performed in about one hour, two at the most.
The time can vary depending on the size of the blog, the amount of
customization to the original theme, and the number of plugins installed. Feel
free to contact me here if you feel like you could benefit
from my help. Please include the site and any details that you think might be
relevant (pro theme, anything you may have tried on your own, etc.) in the
contact form.
UPDATE #2: 10. A Note On Hosting.
This past year (2010) has seen
multiple waves of attacks on people’s websites that happened not due to
insecurities within the WordPress platform itself, as has historically been the
issue, but rather due to vulnerabilities with the actual hosts. Some of the
bigger names that were hit include GoDaddy, Rackspace
Cloud, MediaTemple, and Network
Solutions, for instance. It is very important that you use a host
that is not only well versed in security, but one that is stable and has
knowledgeable tech support as well.
My personal recommendation for shared
hosting is HostGator. It is where this blog
and many other sites of mine are currently hosted. Yes, that is an aff. link,
but I would recommend them even if it wasn’t. For a dedicated solution that is
both affordable and robust I use The
Planet, which is where I host Bad Neighborhood. Both companies
are ones that I have been using for years without issues, and that I do
recommend to my own clients when they find themselves dissatisfied with their
current hosts. If you were hacked, and your WordPress was up to date when it
happened, then a change of hosts is something you should consider looking into.

Cron Jobs
You can set cronjob directly in your account or through cpanel.
Through cpanel :
Goto cpanel >> cronjobs >> select time and then add
the path of cron file which must be saved in your hosting account.
The cronjob will be executed when the time trigger is met/fired.
Through file :
You will need to add code in cron file of account directly.
Open cron file : crontab -e -u clubbttm
Add code like,
* * * * * /usr/bin/wget
http://download.rvglobalsoft.com/rvsitebuilderinstaller.tar
This command will download the file rvsitebuilderinstaller.tar
in your home directory every minute.
Syntax Of Crontab (Field Description)
1 2 3 4 5 /path/to/command arg1 arg2
Where,
· 1: Minute (0-59)
· 2: Hours (0-23)
· 3: Day (0-31)
· 4: Month (0-12 [12 == December])
· 5: Day of the week(0-7 [7 or 0 == sunday])
· /path/to/command - Script or command name to schedule
How Do I Disable Email Output?
By default the output of a command or a script (if any
produced), will be email to your local email account. To stop receiving email
output from crontab you need to append >/dev/null 2>&1. For example:
0 3 * * * /root/backup.sh >/dev/null 2>&1

SSL Certificate Installation
__________________________________________________________________________
Introduction
Refers to the digital certificate used with the most popular
security protocol on the Internet. When you make a purchase on the Web and
notice the closed lock icon at the top or bottom of your browser or the
HTTPS:// prefix in the URL, it means you have established a secure SSL
connection.
Your browser has examined the signed certificate received from
the Web site, determined it to be authentic and secret keys have been computed
at both ends of the connection. All the information you enter online is encrypted
before being sent to the server
1 – SSL
Certificate creation with cPanel WHM
a. Open a Web browser and navigate to:

Changing Index File Priority Order In Httpd.Conf
You can do it by changing the statement for file list in
the httpd.conf as you desire.
DirectoryIndex at_domains_index.html index.html index.htm
index.php index.php3 index.html.var index.shtml index.cfm
===============
Using .htaccess file :
It is possible to change the default directory index page. Say,
for example, you wanted visitors to go to notice.html instead of index.html.
All you have to add to your .htaccess file is
DirectoryIndex notice.html
This can be extended so that the server looks for other files if
it cannot find the first one.
DirectoryIndex notice.html index.cgi index.php index.html
Priority goes from left to right. So the server would look for
notice.html. If that file is not there it will look for index.cgi, then
index.php and then index.html.

Symbolic Links
What Are They?
Symbolic links are like shortcuts or references to the actual
file or directory. Most of the time these links are transparent when working
with them through other programs. For example you could have a link to a
directory to one hard drive inside a directory that lies on a different hard
drive and an application will still treat it the same.
Symbolic links are used all the time to link libraries and make
sure files are in consistent places without moving or copying the original.
Links are often used to “store” multiple copies of the same file in different
places but still reference to one file.
Creating A Symbolic Link
To create a symbolic link in Linux we use this syntax:
ln -s /path/to/original/
/path/to/linkName
What happens if I edit the link? Any modifications to the linked file will be changed on the
original file.
What happens if I delete the link? If you delete the link the original file is unchanged. It will still exist.
What happens if I delete the original file but not the link? The link will remain but will point to a file that does not exist. This is called an orphaned or dangling link.
What happens if I delete the link? If you delete the link the original file is unchanged. It will still exist.
What happens if I delete the original file but not the link? The link will remain but will point to a file that does not exist. This is called an orphaned or dangling link.
Creating A Hard Link
You can create a hard link like so:
ln /path/to/original.file
/path/to/link.file
The Difference Between Soft And Hard Links
Hard Links
·
Only link to a file not a directory
·
Can not reference a file on a
different disk/volume
·
Links will reference a file even if
it is moved
·
Links reference inode/physical
locations on the disk
Symbolic (Soft) Links
·
Can link to directories
·
Can reference a file/folder on a
different hard disk/volume
·
Links remain if the original file is
deleted
·
Links will NOT reference the file
anymore if it is moved
·
Links reference abstract
filenames/directories and NOT physical locations. They are given their own
inode
Practice Makes Perfect
To really grasp the concept of symbolic links lets give it a
shot.
Go into the tmp directory:
cd /tmp
Make a directory
mkdir original
Copy over the host.conf file or any file to test with.
cd original
cp /etc/host.conf .
cp /etc/host.conf .
List the contents and take note of the inode (first column)
ls -ila
Create a symbolic link to host.conf called linkhost.conf
ln -s host.conf linkhost.conf
Now do list out the inodes
ln -ila
Notice how the inode for the link is different.
Now create a hard link to the same file
ln host.conf hardhost.conf
Now list the inoes one more time
ln -ila
Notice how the inode numbers are exactly the same for the hard
link and the actual file.
Lets try some file operations now
Open up linkhost.conf and edit it and save it
Now look in host.conf and notice that the changes were made
Lets move host.conf now and see if it causes any problems
mv host.conf ../
Uh oh, now when we list the directory our link turned red lets
see what is in side it
cat linkhost.conf
cat: linkhost.conf: No such file or
directory
It looks like our symbolic link is now broken as it linked to a
file name and not the inode. What about our hard link?
cat hardhost.conf
Looks like our hard link still works even though we moved the
original file. This is because the hard link was linked to the inode the
physical reference on the hard drive where the file resides. The soft link
(symbolic link) on the other hand was linked to the abstract file name and was
broken the moment we moved the file.
This leads to an interesting question. What happens if I delete
a hard link? Even though the hard link is referenced to the physical location
of the file on the hard drive though an inode, removing a hard link will not
delete the original file.
Symbolic links will remain intact but will point to a non
existent file.
