Central Server (Bumblebee)

Part of the LENSS project requires a central server to collect, sort, store and present all data gathered from the sky sensors.

The base for our server is the computer used to host the old StarsBase. It is a computer from around 2010 sporting an AMD Athlon x2 2.0GHz CPU and 2GB of RAM.

CentOS 7

Ethernet Issue

The server is currently operating with a copy of CentOS 7. One issue with this distribution is the outdated NVIDIA CK804 LAN chipset as outlined in this CentOS forum post. To get LAN to work, install the attached kmod-forcedeth package:

• Navigate to the directory containing the kmod-forcedeth package.
• Run sudo yum install kmod-forcedeth-0.64-3.el7_5.elrepo.x86_64.rpm to install the driver.

Once the driver is installed, follow this guide to setup a network connection.

After installing the package and verifying ethernet is working, install the ELRepo repository following their guide here to be sure the package continues to get updates.

Connecting to the Server

Connections are currently made with SSH. The server's current IP is 192.168.1.10, the external port is 426, and the M.A.C. address is 00:14:85:38:63:01.

Standard SSH format ~$ ssh <username>@<device_ip>

Connecting remotely ~$ ssh -p <external_port> <username>@glasoffice.ddns.net
