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 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.

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@vmname.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, and OSGeo7 are all Ubuntu 18.04 servers running LXD. Note that OSGeo3, OSGeo4, and OSGeo7 are all LXD Hosts running (at this moment all LXC containers). These instructions therefore apply to OSGeo3, OSGeo4, and OSGeo7 Hosts. 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 VPN -- details in osgeo7-secure container for each.

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 successiv section sto know what's on which machine.

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 will need an ssh key on download already to do so. If you do not already have a key installed, put in a SAC Ticket Request

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!

This is new home of download.osgeo.org, it's a debian 9 container (now locked down to only allow ssh key access / ldap auth) for ssh. It is running nginx instead of apache that the old ran. It has webdav with single local htaccess account geotools for geotools bot use.

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 with your private key.

You can put in a ticket to request such access.

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 

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"

Then to access say the wordpress-dev container, you'd do the below where your_id could be your osgeo id or a local account on that container 

ssh your_id@osgeo4-wordpress-dev

osgeo3

osgeo3 physical server was rebuilt March 2020 with new disks and power supply, as an Ubuntu 18.04 with LXD. It will be used to run production, but moderately risky things. Refer to SAC:Old-osgeo3 for past history before osgeo3 was rebuilt. osgeo3 is a hosted by OSUOSL - can be accessed via ssh tech_dev@osgeo3.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.

sshing into osgeo3 containers

Note that all the containers are closed off from direct ssh access except for the hop.osgeo3.osgeo.org. To access the other containers, you need to hop through hop.osgeo3.osgeo.org. hop container has port 22 open but requires ssh access, you need to be added to shell group and have your ssh keys registered on your profile https://id.osgeo.org/ldap/edit). Users who’ve been granted rights can hop thru it to other containers using hop.osgeo3.osgeo.org as name. Other containers may or may not allow password access. It's up to the those who manage the internal containers.

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

# this is only needed if you you use different private keys for different servers
Host hop.osgeo3.osgeo.org
  IdentityFile "path/to/your/private/key"

Host osgeo3-*
  ProxyCommand ssh your_osgeo_id@hop.osgeo3.osgeo.org -W $(sed -e "s/^osgeo3-//;s/$/.lxd/" <<< "%h"):%p
  IdentityFile "path/to/your/private/key"

Then to access say the nexus container, you'd do the below where your_id could be your osgeo id or a local account on that container 

ssh your_id@osgeo3-nexus
