Check if the cPanel Ports are Open

Posted by: admin  :  Category: cPanel & WHM, Linux Server Hosting, Tips & Tricks

As experienced by some of our clients, most especially those students who are working behind a network that utilizes web filtering softwares, the non-standard HTTP ports cPanel works with causes them minor headaches. Usually cPanel can be opened from:

  1. http://yourdomainname.com/cpanel
  2. http://yourdomainname.com:2082
  3. http://cpanel.yourdomainname.com

 

At times, local firewalls allow only access to sites on port 80. If that will be the case, use the last URL. Note that the third address is a web-based proxy which provides you with the option to access your cPanel via the default HTTP port 80. This helps if your Internet Service Providers (ISP) blocked ports 2082 and 2083.

You may check if the ports are blocked executing the following commands:

If you are running Windows do the following:

  1. Click Start
  2. Click Run
  3. Type cmd
  4. Type telnet yourdomainname.com 2083
  5. Type telnet yourdomainname.com 2082

If you are running Linux do the following:

  1. Start your Linux/Mac OS console terminal
  2. Type telnet yourdomainname.com 2083
  3. Type telnet yourdomainname.com 2082

If the port is not blocked the results should look like the following one. Trying IP_of_the_server ( 10.10.10.10 for an example )…

Connected to servername.com.
Escape character is ‘^]’.

Different result will means that the port is blocked.

For Windows 7 users:

Telnet is rarely used these days, thus by default, it was activated in Windows 7 (same goes with Windows Vista). As Telnet is very insecure and whenever you have the choice, you should always use SSH. You may,however, re-activate Telnet by following these steps:

  1. Start
  2. Control Panel
  3. Programs and Features
  4. Turn Windows features on or off
  5. Check Telnet Client
  6. Hit OK

After that you can start Telnet via Command Prompt.
