Setup

As of 2021-03 the ssh port of the main host (the physical server) is 2222 and there is only one non-root account on it and can only be accessed via key access. Keys are deployed using AnsibleDeployment repo of gitea

It has an LXD installed from snap.

So to SSH - ssh tech_dev@osgeo3.osgeo.osuosl.org -p 2222

It has 2 public ips:

140.211.15.26 ( osgeo3.osgeo.osuosl.org ) = not currently mapped to anything aside from 2222 ssh) planned for disaster should say osgeo7 go down and all need to be remapped
140.211.15.6 web-osgeo3.osgeo.osuosl.org

For console access, you need to have OpenVPN installed and vpn config for OSUOSL. Once connected it can be accessed via:

``` apt install ipmitool ipmitool -I lanplus -H osgeo3.osuosl.oob -U tech_dev -P passwordhere sol activate ``` or web interface:

http://osgeo3.osuosl.oob

Some configurations of this machine are deployed using AnsibleDeployment It was upgraded in 2021 from Ubuntu 18 to Ubuntu 20.04.
