Server replied: 110 Can’t open SMTP stream

Written by AlanV on October 15, 2008 – 5:22 am -

This error occurs most of the time on cPanel servers while sending an email from Squirrelmail.

Error: Server replied: 110 Can’t open SMTP stream

Open the file /usr/local/cpanel/base/3rdparty/squirrelmail/config/config.php and change

$useSendmail = false;

to:

$useSendmail = true;

Save and exit this file. You will be able to send emails from Squirrlemail

mod_limitipconn on cPanel

Written by Pravin on October 14, 2008 – 9:45 am -

This installation is for Apache 2.x

Download mod_limitipconn & untar the file. Compile mod_limitipconn with apache using following command.

/usr/local/apache/bin/apxs -cia mod_limitipconn.c

Add following line to /usr/local/apache/conf/httpd.conf, inside a virtual host:

<IfModule mod_limitipconn.c>
<Location />
MaxConnPerIP 5
# exempting images from the connection limit is often a good
# idea if your web page has lots of inline images, since these
# pages often generate a flurry of concurrent image requests
NoIPLimit image/*
</Location>
</IfModule>

Example:

<VirtualHost 192.168.2.5:80>
ServerAlias example.com
ServerAdmin webmaster@example.com
DocumentRoot /home/example/public_html
BytesLog domlogs/example.com-bytes_log
User iowncail
Group iowncail
<IfModule mod_php4.c>
php_admin_value open_basedir “/home/example/:/usr/lib/php:/usr/local/lib/php:/tmp”
</IfModule>
<IfModule mod_php5.c>
php_admin_value open_basedir “/home/example/:/usr/lib/php:/usr/local/lib/php:/tmp”
</IfModule>
ServerName www.example.com
<IfModule mod_limitipconn.c>
<Location />
MaxConnPerIP 3
# exempting images from the connection limit is often a good
# idea if your web page has lots of inline images, since these
# pages often generate a flurry of concurrent image requests
NoIPLimit image/*
</Location>
</IfModule>
User example
Group example
CustomLog /usr/local/apache/domlogs/example.com combined
ScriptAlias /cgi-bin/ /home/example/public_html/cgi-bin/
</VirtualHost>

Then restart apache service.

The biggest problem here is that when easyapache will be done in the server, the above changes will be overwritten. To avoid this you will have to do following changes.

mkdir -p /usr/local/apache/conf/userdata/std/1/example/example.com

Make a file called custom.conf and in it add.

<Location />
MaxConnPerIP 3
# exempting images from the connection limit is often a good
# idea if your web page has lots of inline images, since these
# pages often generate a flurry of concurrent image requests
NoIPLimit image/*
</Location>

Then run

/scripts/ensure_vhost_includes –user=example

Where example is the account username and example.com is the account example name. Then restart apache.

VPS vs Shared Hosting

Written by Swapnil on September 25, 2008 – 10:44 am -

Why most of the users prefer VPS and Not Shared Hosting….

VPS provides some interesting feature which are also available with Dedicated servers.

* Full Root Access & ability to install customized script.
* Define the server environment for customer.
* Isolated and protected from other domain on the server which may be abusing the server or overusing server resources.
* Dedicated mail, MySQL, FTP, http server.
* Dedicated Outgoing MailServer IP.

We can consider SHARED HOSTING is like living in an apartment building and sharing your neighbours’ problems. You hear their music through the wall. If one of them leaves the main door open, your security is at risk.

On a shared server, all the website hostings share the operating system and resources. Problems with your neighbours’ website hostings can slow down the server performance or require it to be shut down while the problem is being fixed. The slowdowns may also resulted from having too many website hostings on a server. Your site’s security depends in part on decisions made by your web host and, perhaps, your neighbours too.

Depending on your neighbours and, to a larger extent, your web host, you may have few or no problems with a shared hosting account. By sharing the resources, the cost is more economical than a VPS Hosting. Furthermore, for a basic website hosting, you require little or no technical knowledge to maintain your website hosting.

The majority of website hostings are on shared servers.

Where VPS Hosting HOSTING is more like living in a townhouse with your own private yard, and without ever hearing your neighbours. The only common area you share is the parking area and entrance; all traffic goes through one network port. In contrast to apartments or shared hosting accounts, you pay more for a VPS Hosting, but you can do what you want with the space, and your neighbors’ problems aren’t your problems.

VPS Hosting gives you the features and functionality of a dedicated server without the cost of building and maintaining one. If you need to host unlimited domains, have complete control of your environment and run your own applications, then you will benefit from having a VPS Hosting. In addition, a VPS Hosting provides the ability to manage your dedicated environment directly through SSH or Remote Desktop Connection. In addition, you can add a control panel like cPanel to our Linux VPS Hosting Plus plan. The control panel enables the administrative user to perform actions to their VPS Hosting immediately, without having to contact support to have a technician to complete any necessary requests.

Migrating Cpanel Servers

Written by Swapnil on September 17, 2008 – 1:52 pm -

Moving all the accounts between two Servers that host the same control panel is usually not a very difficult process.

You need to move all domains from the present server to the new server. At the same time, you need the whole move done perfectly and with zero downtime for all domains. In addition, you need to move even your nameservers between two different datacenters. Its pretty complicated.
