![]() ![]() ![]() Tailscale manages key distribution and all configurations for you. To connect devices using Tailscale, you install and log in to Tailscale on each device. Every pair of devices requires a configuration entry, so the total number of configuration entries grows quadratically in the number of devices if they are fully connected to each other. It’s straightforward, particularly for a VPN. The configuration includes information about the device (port to listen on, private IP address, private key) and information about the peer device (public key, endpoint where the peer device can be reached, private IPs associated with the peer device). To connect two devices, you install WireGuard on each device, generate keys for each device, and then write a text configuration for each device. ![]() WireGuard is typically configured using the wg-quick tool. configuring and running WireGuard directly. You might decide to use WireGuard directly, without Tailscale. We designed Tailscale to make it easier to use WireGuard to secure your network connections. Tailscale is built on top of WireGuard we think very highly of it. With a large network it could cause thousands of database queries for the initial recovery.Should I use Tailscale or WireGuard® to secure my network? The answer is yes! Clearing the cursor is an alternative way to recover the lost addresses without a server restart but has the effect of increasing load on the database. ![]() The only way to restore the lost addresses is to stop and start the servers from the web console which will cause the entire pool to clear. The servers remain in the running state even when the Pritunl service is restarted. The TTL index should be removed after the recent updates allowing the system to function. Those removed IP addresses would be lost and eventually no dynamic addresses would be available. This caused the IP documents to be removed by MongoDB after the client disconnected and the timestamp was not updated. The problem occurred when a TTL expiring index was left behind from a previous design. If none are found additional IP addresses are added starting at the cursor. On future connections the server first attempts to find and update an existing IP that contains null user fields. Once a client disconnects the IP address remains in the database, the user and connection ID that was using the address is cleared from the IP document. What can be the source of the problem and how should I avoid this? There seems to be no mongodb issue (from the rvice and mongodb log I can tell).Īfter I re-started the pritunl server via web UI, the symptom was gone and started to work well. This is the snippet of the log, which denies the second connection of a user: Unable to assign ip address, pool full When there is no connection from a user (so the web UI says offline) it accepted one connection but not more. The pritunl server suddenly denied all multiple-device connection of any user, including newly-created one, making an error "unable to assign ip address, pool full". We have been running a single pritunl server (now v.68) on ubuntu 20.04.3 machine, where dozens of clients can connect, with multiple device feature enabled. Hi, first of all many thanks to your great programs. ![]()
