Multicast DNS

August 8, 2026 ยท View on GitHub

By default, the xpra server will advertise the session it creates on the local network using Multicast DNS.

To turn off this feature, use the mdns=no option.

Usage

To view the list of sessions, run:\ `xpra list-mdns`

To use the GUI mdns session launcher, run:
xpra mdns-gui

The user interface should look like this: mdns gui

And you should be able to connect to those sessions simply by pressing the "connect" button.

Limitations

* some features are only available in newer versions * some platforms may not have the required libraries * IPv6 addresses are published since version 5.0, with the exception of the IPv6 loopback address which `python-zeroconf` does not support - see [#1345](https://github.com/Xpra-org/xpra/issues/1345). \ It can be enabled at your own risk with `XPRA_ZEROCONF_IPV6_LOOPBACK=1`
