mDNS does not work with mirrored network mode

[lprobsth]

Windows Version

Microsoft Windows [Version 10.0.22631.3880]

WSL Version

2.2.4.0

Are you using WSL 1 or WSL 2?

• WSL 2
• WSL 1

Kernel Version

5.15.153.1-2

Distro Version

Ubuntu 22.04

Other Software

No response

Repro Steps

• Install WSL2 with Ubuntu
• Enable mirrored network mode:

# Settings apply across all Linux distros running on WSL 2
[wsl2]

networkingMode=mirrored

• Ping a device in the same network as the computer with its local hostname:

ping server.local

Expected Behavior

WSL2 should correctly resolve the local / mDNS hostname to the correct IP address:

$ ping server.local
PING 192.168.178.53 (192.168.178.53) 56(84) bytes of data.
64 bytes from 192.168.178.53: icmp_seq=1 ttl=64 time=3.98 ms
64 bytes from 192.168.178.53: icmp_seq=2 ttl=64 time=2.20 ms
64 bytes from 192.168.178.53: icmp_seq=3 ttl=64 time=2.81 ms

Actual Behavior

The mDNS hostname is not resolved:

ping: server.local: Name or service not known

Same issue here WSL2 Ubuntu

[Emaro]

I have the same issue. A fix would be appreciated.

[CatalinFetoiu]

thanks for reporting the issue

we have updated the docs to include details about how to resolve .local names in WSL. Please refer to https://learn.microsoft.com/en-us/windows/wsl/troubleshooting#resolve-local-names-in-wsl

let us know if you have any questions

[lprobsth]

I tried the configuration with libnss-mdns and nsswitch.conf from the docs but it does not work. Is there something else I can provide?

[CatalinFetoiu]

@lprobsth thanks for following up
please make sure you are using latest WSL build (2.3.17)
I recommend also confirming that mirrored mode was successfully enabled - you can do this by running "wslinfo --networking-mode" in your distro

if you still encounter issues after confirming the above, please collect networking logs using instructions at https://github.com/microsoft/WSL/blob/master/CONTRIBUTING.md#collect-wsl-logs-for-networking-issues

[lprobsth]

I have installed WSL build 2.3.17. The problem seems to persist.

Here is the log file. The networking log script did not create an archive - so I zipped the output from the log directory. I hope this is correct.

@lprobsth thanks

the logs don't show mdns traffic being sent by Linux

could you please collect and share the output of "sudo strace ping server.local" ? that might give us a hint on why no mdns requests are sent

[johnp789]

I'm using systemd and systemd-resolved in my Ubuntu WSL2 distribution, and resolvectl showed that mDNS is disabled for the eth0 interface. As a workaround, I did this:

cat  << EOF | sudo tee /etc/systemd/network/10-eth0.network
[Match]
Name=eth0

[Network]
MulticastDNS=true
EOF

sudo networkctl reload

[wesgeorge]

I'm running into a similar issue.

$ wslinfo --wsl-version
2.3.26
$ wslinfo --networking-mode
mirrored

I also tried disabling dnsTunneling in .wslconfig.

libnss-mdns is installed, and the nsswitch.conf file exists (I didn't put it there), though I note it has a slightly different configuration than the referenced link- it uses mdns4_minimal instead of mdns_minimal.

$sudo apt install libnss-mdns
