For the installation of a LiveConfig client you need:

  • “root access” at the server to be installed (via console or SSH)

  • about 15 MB free disk space

  • a running LiveConfig server for the client to connect to

  • a license key for the LiveConfig client (standard license)

Please also check for:

  • correct time: you need the correct time on your server - otherwise you might experience problems with SSL certificates, outbound e-mail and validity of the LiveConfig license. We recommend to install the package ntp (Network Time Protocol).

  • valid host name & reverse DNS: the server requires a valid host name. Using the command hostname -f you’ll see the complete (fully-qualified) name. This consists of a host name and a domain name.

    Example: for a web server with the name, the file /etc/hostname should contain only www; in /etc/hosts there should be a line with <IP address>  <complete name>  <hostname>, in this case ##.##.##.##  www. If everything is configured correctly, the command hostname (without any options) will return just www, and hostname -f will return

    A valid reverse DNS name is especially important if you want to send e-mails with your server. Most mail servers check if the name of the peer mail server matches its reverse DNS name.

File system quota

If you want to use the server for webspace, it’s recommended to enable file system quota. This is required to limit and to check the disk space used by webhosting subscriptions.

See the Knowledge Base for details on enabling file system quota.

Firewall settings

The LiveConfig client does not require any firewall settings for incoming connections; only outgoing connections to the following destinations must be allowed:

  • TCP port 788 to the LiveConfig server (for LCCP connections)

  • TCP port 443 (HTTPS) to the LiveConfig license server (

  • optionally: TCP port 443 (HTTPS) to the update server ( for installing web applications, as well as port 80 or 443 to the download server of the respective application.

The LCCP port settings of the LiveConfig server can be changed in the configuration file.
