OpenVPN is our server->server VPN solution. It is deployed in a routeless manner and uses puppet managed keys for authentication. All hosts should be given static IP's and a hostname.vpn.fedoraproject.org DNS address.
Contact Information
Owner: Fedora Infrastructure Team
Contact: #fedora-admin, sysadmin-main
Location: Phoenix
Servers: bastion (vpn.fedoraproject.org)
Purpose: Provides vpn solution for our infrastructure.
Add a new host
Create the keys
From puppet1 check out the private repo:
git clone /git/private chmod 700 private cd private/vpn/openvpn
Next prepare your environment and run the build-key script. This example is for host "proxy4.fedora.phx.redhat.com"
. ./vars ./build-key $FQDN git add . git commit -a git push
Create Static IP
Giving static IP's out in openvpn is mostly painless. Take a look at other examples but each host gets a file and 2 IP's. Also make sure to restart puppet on bastion *before* pushing changes out to hour new node.
git clone /git/puppet vi puppet/modules/openvpn/files/ccd/$FQDN
The file format should look like this:
ifconfig-push 192.168.1.314 192.168.0.314
Basically the first IP is the IP that is contactable over the vpn and should always take the format "192.168.1.x" and the PtPIP is the same ip on a different network: "192.168.0.x"
Commit and install:
git add . git commit -m "What have you done?" git push
Create DNS entry
After you have your static IP ready, just add the entry to DNS:
From your puppet checkout, run:
vi modules/bind/files/master/vpn.fedoraproject.org git commit -m "What have you done?" git push
Wait for bastion and ns1/2 to get updated, then restart /sbin/service openvpn on the new machine.
TODO
Deploy an additional VPN server outside of PHX. OpenVPN does support failover automatically so if configured properly, when the primary VPN server goes down all hosts should connect to the next host in the list.
