Installing Zimbra

Post-Installation Steps

Now that our Zimbra Collaboration Suite server has been configured and installed, there are a few post-installation steps we will need to complete before moving on. We will be using Red Hat Enterprise Linux 4 to make these changes, however, you could just apply these steps to your operating system. The first step will be to enable our firewall so our server is protected.

Configuring the Firewall

As you will recall, we disabled the firewall when installing our operating system. With Zimbra installed, we can now open up just the ports necessary to successfully use our collaboration server:

1.First, we must login as root on our server by typing su – at the shell prompt.

2.Next, we will open up the firewall configuration tool by typing:

system-config-securitylevel

3.This will open up the Security Level Configuration Tool as shown on the next page. Here we will need to enable the firewall and select the checkbox next to

SSH to allow for remote access to the server (and self access for mail queues management). We will also need to open up the following ports by typing them into the Other ports text box:

•https:tcp

•3930:tcp

•pop3:tcp

•imap:tcp

•imaps:tcp

•ldap:tcp

•pop3s:tcp

•7025:tcp

•5800:tcp

•5900:tcp

•7071:tcp

•3895:tcp

•3894:tcp
