This article explains how to configure tcpwrappers and ssl for use with the Uptime Infrastructure Monitor Linux agent and assumes that you have already installed the utilities on your Linux system.

Before configuring the agent, record the IP address of the monitoring station.

Open the /etc/hosts.allow file in a text editor and add the following line:

uptmagnt : <monitoring station IP address>

Open the file /etc/hosts.deny in a text editor and add the following line:

uptmagnt : ALL


Additional Information

On some systems, to enable the agent to work properly, you may need to add the hosts.allow file even if you do not have a hosts.deny file.

Download, install and configure the Stunnel software, which enables you to encrypt arbitrary TCP connections inside SSL.

Review the tcpd manpage, which explains how to use the access control facility for Internet services.
