It is not recommended to take the backup of the large MySQL database from PHPMyAdmin because there is a risk that it doesn't take the full backup of your database due to large size. You will need to take the backup from command line.

Generally it downloads the incomplete database due to time out in the PHP script.

Quote from: "Alex"Hi,

What are the recommended Wordpress plugins for search engine optimization and which plugins are you using in your Wordpress blog ?

I am using two plugins for Search Engine Optimization. They are as follow:

[1] All in one SEO plugin.
This plugin rewrite the URL as well as you can add your blog name in title of each post.

[2] Google sitemap generator
This plugin generates the sitemap whenever there is a change in the blog (new post, comments, post updates or edit etc.) It also pings to Google, Yahoo, MSN, Ask whenever it generates the sitemap.

Yes, you can install ISAPI rewrite software provided by HeliconTech. It is IIS module and ISAPI filters for URL rewriting. There is free and paid version available for this software. For more details, visit their web site http://www.helicontech.com/.

You do not need to assign the dedicated IP address of your each sub-domain. You just need to assign the dedicated IP address to your main domain.

It is essential that you have been notified whenever someone login to your server. On the server, you can set an email alert when someone login to your server as root.

[1] Login to your server as a root user.

[2] Type the below command:
pico /root/.bashrc

[3] Scroll down to the end of the file and add the following line:

echo 'Root Shell Access on your [ServerName] on:' `date` `who` | mail -s "Alert: Root Access from `who | cut -d"(" -f2 | cut -d")" -f1`" <a href="mailto:[email protected]">[email protected]</a>

[4] Save the file and exit from SSH. Now login to your server and check whether you are receiving the email alert or not.

[1] To check the running processes:
top
Description: This command will display the current running processes on the server. This will help to monitor the current running processes. For more options of this command go through the manual of this command.

man top
[2] To list the files and folders:
ls
Description: This is command will list the files and folders which are in current directory. For more options of this command go through the manual of this command.

man ls
[3] To check running process by particular user:
ps
Description: By adding some parameters to this command you can grep the processes owned by particular user:

Hi Ramesh,

Thanks for sharing it.

It is a good idea to disable root login via SSH. It reduces the security risk. It is also recommended to use SSH protocol 2 and disable SSH protocol 1. SSH protocol 2 is more secure than SSH protocol 1. Following are the steps to disable direct root login and to disable SSH protocol 1:

[1] Login as a 'root' to your server.
[2] Open /etc/ssh/sshd_config file.

Quotepico -w /etc/ssh/sshd_config

[3] Find the below text within file:

QuoteProtocol 2, 1

[4] Uncomment the above line and change it as follow:

QuoteProtocol 2

[5] Now, search the below text:

QuotePermitRootLogin yes

[6] Uncomment the above line and set as follow:

QuotePermitRootLogin no

[7] Save the file and restart SSH service using the below command:

Quote/etc/rc.d/init.d/sshd restart

Now, no one will be able to login as root directly. They have to use su - to get the root access. You will need to add your user to wheel group in cPanel otherwise you will not be able to use su command.

Go for Smartermail 5.5.X which has better anti spam solution as well as you will get good statistics of your server in Smartermail.

Kevin

Smartermail 5.5.X is now out.

Kevin

Smartermail 5.5 is now available which has better anti spam capability then Smartermail 4. If you want to integrate any other third party anti spam solution then I would suggest Declude with Smarter as it is easy to integrate it with Smartermail. Please note that such anti spam software require high resources on the server and it may slow down the performance if you have low configuration server.

Hi,

Sometime you may need to redirect your html or htm (static pages to another URL). You can do this using the META tag redirection. you just need to add the following code in your code to redirect the page:

<META http-equiv="refresh" content="1;
             URL=http://www.webhostingdiscussion.net">

I think the below steps will help you to fix the problem:

1) Install spamd and spamc:

cd /usr/local/directadmin/scripts
./spam.sh
2) Start the spamd:

/usr/bin/spamd -d -c -m 15
3) In order to get exim to use the spamd program, you'll need to make some changes in your /etc/exim.conf. Change:

# Spam Assassin
#spamcheck_director:
#  driver = accept
#  condition = "${if and { \
#      {!def:h_X-Spam-Flag:} \
#      {!eq {$received_protocol}{spam-scanned}} \
#      {!eq {$received_protocol}{local}} \
#      {exists{/home/${lookup{$domain}lsearch{/etc/virtual/domainowners}{$value}}/.spamassassin/user_prefs}} \
#      {<{$message_size}{100k}} \
#    } {1}{0}}"
#  retry_use_local_part
#  transport = spamcheck
#  no_verify
to

# Spam Assassin
spamcheck_director:
  driver = accept
  condition = "${if and { \
      {!def:h_X-Spam-Flag:} \
      {!eq {$received_protocol}{spam-scanned}} \
      {!eq {$received_protocol}{local}} \
      {exists{/home/${lookup{$domain}lsearch{/etc/virtual/domainowners}{$value}}/.spamassassin/user_prefs}} \
      {<{$message_size}{100k}} \
    } {1}{0}}"
  retry_use_local_part
  transport = spamcheck
  no_verify
4) Restart exim:
Redhat:

/sbin/service exim restart
FreeBSD:
/usr/local/etc/rc.d/exim restart
The global spamassassin config file is in /etc/mail/spamassassin/local.cf

You'll want to make sure that you have the correct call to spamc in the spamcheck transport in your exim.conf:

transport_filter = /usr/bin/spamc -u ${lookup{$domain}lsearch*{/etc/virtual/domainowners}{$value}}
If you run debian and are missing perl or some pm files, type:

apt-get install perl-base perl-modules

One of the common error in cPanel after installation is:

/usr/bin/crontab permissions are wrong. Please set to 4755

An easy fix for this error is:

- Login to your server via SSH and shoot out the following command:
- chmod 4755 /usr/bin/crontab

Please note that you will require root access to the server to change the permissions of crontab.

Hi,

Are you referring to maximum file size upload limit (upload_max_filesize) in php.ini or maximum allowed packet for mysql (max_allowed_packet)?

To increase the file upload limit for php, just edit your php.ini and set the desired value for upload_max_filesize. You may need to restart Apache or IIS after modifying the php.ini file. To know the php configuration path, just create a new file with .php extension and write the below code:

<?php
phpinfo();
?>Look at the path set for "Loaded Configuration File".

And to increase the MySQL packet, edit your my.cnf (Linux server) or my.conf (windows), and set the desired value for max_allowed_packet. You will need to restart mysql after making the changes.

It is simple process to install PHPMailer on Windows server. You just need to upload PHPMailer class file inside the 'includes' folder of your PHP installation. Generally the include folder in locate inside your PHP installation directory (c:\php\includes). Make sure you have added this include path in your php.ini files.

That's it.

That's great news. Now, if you do not have credit card then also you can make the payment using 2checkout.

Many host allow to update the Awstats of the domain from 'Update Now' link on Awstats page.

[1] Login to your WHM.
[2] Go to Tweak Settings.
[3] Uncheck the option "Allow users to update Awstats from cPanel" and save it.

There is a function available in PHP to send a mail via PHP script. The function is mail(). However, it is advisable to disable PHP mail() function on the shared hosting server to prevent spamming from the server and allow only SMTP authentication to send the emails via PHP script.

[1] Login to your WHM.
[2] Go to Tweak Settings.
[3] Select the option "Prevent the user "nobody" from sending out mail to remote addresses (PHP and CGI scripts generally run as nobody if you are not using PHPSuexec and Suexec respectively.)" and save it.
