1 Frequently Asked Questions (FAQs)

1.1 Which platforms are supported?

Windows (all versions), Linux (CentOS, Debian, SuSe, Redhat) and Mac (Leopard or higher). All the agents have the same features across all platforms. We have also experimental support for raspberry embedded linux devices.

1.2 What user limitations are there?

There are no limitations. You can use OpGuardian for client support, with friends or for your own setup. You can use it in any situation: professional, educational or personal.

1.3 Can I reuse a previous configuration of a Pandora FMS agent installed on a server?

Yes. Check the configuration file of an OpGuardian installed agent, and check the server IP address and group name, put these parameters on your existing pandora fms agent, enable the remote configuration and that agent will be integrated in your OpGuardian account as a monitoring node.

1.4 What about hacks?

The local agent can be password protected. The password won’t be stored on our servers, only on your agent. The password is necessary to connect to your agent at all times. Even if someone gained access to our database they would be unable to find out your local passwords.

Apart from the local password, you can activate privacy mode which triggers a popup requesting authorization in case of anyone trying to connect locally (via LAN).

To increase security, a two-factor authentication protocol can be activated, requiring a physical token plus a password.

All data passing from your browser to our server is SSL-encrypted, as is the data passing from the agent to our server.

1.5 Which ports does OpGuardian use?

The agent installed on the servers does not listen to any ports; instead, it connects to our servers. Your client (browser) connects to two servers, both via port 443.

For OpGuardian to work, you need an internet connection on the servers with OpGuardian agent installed, and which is configured to output at port 18080/tcp and 41121/tcp. If you need to output via a proxy, this can be configured on the agents.

Please consult the relevant documentation for more information.

1.6 Speeding up the remote desktop

Activating the local connection in an agent creates a direct connection between your browser and the remote device, cutting out our servers and making the connection faster.

You can install a driver on Windows which speeds up the remote device by 30%.

You can find more info at Documentation in the downloads area.

1.7 Keyboard shortcuts don't work on on the shell

Contact us through our forum.

In this case, please write to us at our forum. We have not tested all the possible combinations of languages and browsers. Please indicate the sequence of commands/characters, the language, the browser and the SO.

1.8 Can I run eHorus at the same time as Logmein or Teamviewer?

Of course, without any problem.

1.9 What if I need to speak to someone?

Get in touch via the eHorus forum, in English or Spanish. We will be happy to help.

1.10 Why does the connection sometimes break down?

The agent will cut the connection with the client if it detects more than five minutes of inactivity in order to avoid blocking the connection.

1.11 The agent is down and I can't connect to the remote device

The agent will try to connect to the server every time the connection is lost, so if your internet connection is interrupted it is not a problem. The agent will reconnect by itself.

If the server appears as down, it may be because it is saving energy and network functions are sleeping. In this case you may need to reconfigure it to so it does not enter sleep mode, or that only the monitor enters sleep mode.

1.12 How much bandwidth does the eHorus remote desktop consume?

It’s difficult to put a number on it because a desktop with a resolution of 800×600 and 256 colors isn’t the same as a desktop with a resolution of 1920×800 with millions of colors. You could average it out at a bandwidth consumption of 5Kbytes/sec (40kbps) under standard conditions.

1.13 I am having trouble typing in the terminal on an Android device.

Predictive text can interfere with OpGuardian. Disable it and try again.

1.14 Can I mix remote monitoring and local monitoring in the same node/agent?

No, local monitoring (based on agents) and remote/network monitoring must be one in different nodes.
