There is utility in logging traffic statistics that occurs at the physical layer. That is, in order to send packets virtually to a particular tailscale IP address, what physical endpoints did we need to communicate with? This functionality logs IP addresses identical to what had always been logged in magicsock prior to #5823, so there is no increase in PII being logged. ExtractStatistics returns a mapping of connections to counts. The source is always a Tailscale IP address (without port), while the destination is some endpoint reachable on WAN or LAN. As a special case, traffic routed through DERP will use 127.3.3.40 as the destination address with the port being the DERP region. This entire feature is only enabled if data-plane audit logging is enabled on the tailnet (by default it is disabled). Example of type of information logged: ------------------------------------ Tx[P/s] Tx[B/s] Rx[P/s] Rx[B/s] PhysicalTraffic: 25.80 3.39Ki 38.80 5.57Ki 100.1.2.3 -> 143.11.22.33:41641 15.40 2.00Ki 23.20 3.37Ki 100.4.5.6 -> 192.168.0.100:41641 10.20 1.38Ki 15.60 2.20Ki 100.7.8.9 -> 127.3.3.40:2 0.20 6.40 0.00 0.00 Signed-off-by: Joe Tsai <joetsai@digital-static.net>
Tailscale
Private WireGuard® networks made easy
Overview
This repository contains all the open source Tailscale client code and
the tailscaled daemon and tailscale CLI tool. The tailscaled
daemon runs on Linux, Windows and macOS, and to varying degrees on FreeBSD, OpenBSD, and Darwin. (The Tailscale iOS and Android apps use this repo's code, but this repo doesn't contain the mobile GUI code.)
The Android app is at https://github.com/tailscale/tailscale-android
The Synology package is at https://github.com/tailscale/tailscale-synology
Using
We serve packages for a variety of distros at https://pkgs.tailscale.com .
Other clients
The macOS, iOS, and Windows clients use the code in this repository but additionally include small GUI wrappers that are not open source.
Building
go install tailscale.com/cmd/tailscale{,d}
If you're packaging Tailscale for distribution, use build_dist.sh
instead, to burn commit IDs and version info into the binaries:
./build_dist.sh tailscale.com/cmd/tailscale
./build_dist.sh tailscale.com/cmd/tailscaled
If your distro has conventions that preclude the use of
build_dist.sh, please do the equivalent of what it does in your
distro's way, so that bug reports contain useful version information.
We require the latest Go release, currently Go 1.19.
Bugs
Please file any issues about this code or the hosted service on the issue tracker.
Contributing
PRs welcome! But please file bugs. Commit messages should reference bugs.
We require Developer Certificate of
Origin
