Cannot Establish Connection to Server using the Web Browser

zahian84 · 11-26-2018, 06:04 AM

Hi all,

I am using centos 7 in VMWare. I want to use Snort IDS console and successfully installed Snort, Aanval and all the requirements in my centos. After the installation, I suppose to go to Aanval authentication page by typing 10.1.1.164 at my web browser. However, the web browser cannot establish the connection to the specified server.

Please help me.

Have you installed a web server on the VM?

Yes, I already installed Apache web server.

Let's do a steeplechase. But before we start, please ensure that the Snort IDS console uses default web server port 80.

First hurdle: To check if the server is running at all, access its address from the command line in the VM:

Code:

curl 10.1.1.164 
curl localhost

Next hurdle: Centos implements a very strict firewall that doesn't permit access to any network port except 22 (for SSH). On the VM, open the firewall for web services:

Code:

firewall-cmd --add-service http   # I hope that is correct - use the man page to check

Third hurdle: It might be that VMware prevents you from accessing the VM. I can't help you with that though.
