Infrastructure of OSGeo System Administration Committee (SAC)

For emergency plans see: SAC:Admin and Troubleshooting


Servers at OSL

Open Source Labs - 4 physical machines containing x virtual machines.


Logging into Physical Machines

Currently we have osgeo6 and backup.osgeo.osuosl.org that are physical machines under LDAP control.

Note this does not apply to osgeo3, osgeo4, osgeo7, osgeo9 lxd hosts. Refer to those sections for instructions on logging in. If hanging, see OSL for how to open a ticket with OSUOSL's support.

This section currently only applies to osgeo6 and backup.

All SAC administrators have LDAP auth to the OSL Machines.

To ssh into a server using your LDAP account, you can do the following replacing your_osgeo_login with your OSGeo login and vmname with the vm name of the server at OSL. 

 ssh your_osgeo_login@servername.osgeo.osuosl.org

When prompted for password, use your OSGeo Login password.


SAC:Primary Administrators also have ssh key access in case LDAP is down and that will also apply to the physical machines. Worst case scenario use the information on Open Source Labs to file a ticket (SAC members only). Direct connection to virtual machines is by appending it's vm alias to .osgeo.osuosl.org.

Logging into LXD Hosts

OSGeo3, OSGeo4, OSGeo7, OSGeo8, and OSGeo9 are all Ubuntu 20.04 servers running LXD. LXD is a management system for LXC containers and QEMU VMS. LXD has a channel that covers its features.

To directly access the host, you go thru port 2222 

  ssh tech_dev@server_name.osgeo.osuosl.org -p 2222

Only SAC:Primary Administrators have their ssh key installed under that account. In order to access via KVM of these in event servers do not come up on a reboot, you need to go thru OSU OSL OpenVPN. To get an OpenVPN account, you need to put in a support ticket to support@osuosl.org. In order to qualify for an OpenVPN account, you need to be an OSGeo SAC administrator. You will also need to install OpenVPN client) to use your OpenVPN account.

Each host on the private KVM side is named https://osgeo8.osuosl.oob -- where replace osgeo8 with the relevant host. The .oob is the private network, so doesn't work unless you are connected to via OpenVPN.

The browser interface is sometimes clunky, so you might want to use ipmitool installable on linux/unix or wsl using relevant package manager. KVM passwords are stored in SAC password-store.


A convenient block to add to your ~/.ssh/config to easily login to osgeo's LXD hosts follows: 

   Host osgeo?
     User tech_dev
     HostName %h.osgeo.osuosl.org
     Port 2222

Then you would be able to log into those hosts with commands like: 

   ssh osgeo7

Logging into LXD Containers and VMs

A convenient block to add to your ~/.ssh/config to easily login to osgeo's LXD hosted containers and vms is the following: 

  Host osgeo*-*
    ProxyCommand ssh hop.$(sed -e "s/-.*//" <<< "%h").osgeo.org -W $(sed -e "s/^osgeo[^-*]-//;s/$/.lxd/" <<< "%h"):%p
    # this is only needed if you you use different private keys for different servers
    IdentityFile "path/to/your/private/key"

Then you'll be able to access a LXC Container or QEMU VM on machine `osgeo3` with: 

  ssh osgeo3-matrix

And one on machine `osgeo7` with: 

  ssh osgeo7-secure

Note you still need to know where each LXC host is hosted... See successive sections to know what's on which machine.

pretalx

Ubuntu 20.04 with OSGeo LDAP and Docker installed. pretalx software runs in Docker. https://talks.osgeo.org - for OSGeo Talk collection and voting See Pretalx

wiki

(wiki.osgeo.org) - debian10 lxd container with ldap/ssh (MediaWiki 1.34, 10.3.22-MariaDB, PHP 7.3)

Note that this is a rebuild of wiki.osgeo.org that used to be on osgeo7 old-wiki container. Move 2020-05-22 Setup steps are at wiki container setup

osgeo 7

Server added June 2018. Intended to replace osgeo3 and old osgeo4 (before reformat). Configuration Details

Container setup of all the osgeo7 servers is located in https://git.osgeo.org/gitea/sac/osgeo7/wiki/_pages

Running LXD 3 snap based container management -- LXD version 3.17 as of 2019-09-15

Accessing osgeo7 containers via ssh

Only the download.osgeo.org is directly exposed ssh via port 22. To access the other containers, you can tunnel thru download.osgeo.org -- You need to be in the shell group to be able to access download and the other servers. If you are not already put in a SAC Ticket Request. You also need to have your public key registered. To do so edit your profile [1] (and put in your public key)

A convenient block to add to your own `.ssh/config` file follows: 


Host osgeo7-*
  ProxyCommand ssh your_osgeo_id@hop.osgeo7.osgeo.org -W $(sed -e "s/^osgeo7-//;s/$/.lxd/" <<< "%h"):%p
  IdentityFile "path/to/your/private/key"

With the above in place, you can connect to any container using: 

 ssh your_id@osgeo7-<container_name>

Troubleshooting: In case of "Permission denied (publickey)." after an update to a modern openSSH version, it might well be that your ssh key (RSH key) is disabled in your client in favour of more modern cyphers.

Ugly workaround: add one line `PubkeyAcceptedKeyTypes ...` in `.ssh/config`, to re-enable RSA keys for now (consider to generate a new key): 

 vim .ssh/config
 ...
 Host *
    ...
    PubkeyAcceptedKeyTypes +ssh-rsa

... but better read e.g. here!


Services on osgeo7

Download

In order to be able to log in or sftp

  • You must be a member of the OSGeo shell group which can be granted from another person in shell group - Shell
  • Once you are in shell group, go to https://id.osgeo.org/ldap/edit and put in your public key.

You should then be able to log into download (and all other hop servers on the other hosts) with your private key.

You can put in a ticket to request such access.

nginx

Proxy that routes all http/https traffic for the other containers (can be accessed via osgeo7 host lxc or ubuntu@osgeo7-nginx if your key is installed on ubuntu user). The nginx container holds the letsencrypt https SSL certs for all the containers and handles the renewal of the letsencrypt certs using certbot renew cronjob. Prometheus server to collect all monitoring logs from OSGeo7 (only accessible by OSGeo3), these get queried via monitor.osgeo.org (running on osgeo3) via grafana server.

  • See SAC:Backups for details.

osgeo4

osgeo4 is a real server managed by OSUOSL - can be access via ssh tech_dev@osgeo4.osgeo.osuosl.org -p 2222 (only people with their access keys installed can log in and doesn't allow password access) - password for tech_dev is in the secure container (on osgeo7) / access folder.

In August 2019 the server had new power supply put in and replacement disks. It was reformatted with Ubuntu 18.04.3 to serve as secondary LXD host to osgeo7 zfsutils-linux was installed so lxd can use zfs for storage.

sshing into osgeo4 containers

Note that all the containers are closed off from direct ssh access except for the hop.osgeo4.osgeo.org. To access the other containers, you need to hop through hop. hop container has port 22 open but requires ssh access so users who’ve been granted rights can hop thru it to other containers using hop.osgeo4.osgeo.org as name.

A convenient block to add to your own .ssh/config file follows where your_id could be your osgeo id or a local account on that container 

Host osgeo4-*
  ProxyCommand ssh your_osgeo_id@hop.osgeo4.osgeo.org -W $(sed -e "s/^osgeo4-//;s/$/.lxd/" <<< "%h"):%p
  IdentityFile "path/to/your/private/key"
  User your_id

Then to access say the wordpress-dev container, you'd do the below 

ssh osgeo4-wordpress-dev
