WSLHostPatcher was running fine until this morning. After some digging around I found that it seems my current version of wsl2 is using wslrelay.exe instead of wslhost.exe to take care of port listening on windows side, which I think cause current version of WSLHostPatcher stop working.

I'm on windows 10 22H2，and my wsl2 version is 1.1.60_x64 (at least base on the binary path). Here's a segment of netstat -anob command output related to wsl. Hope this can help fixing the code.

  TCP    [::1]:22               [::]:0                 LISTENING       17584
 [wslrelay.exe]
  TCP    [::1]:80               [::]:0                 LISTENING       17584
 [wslrelay.exe]
  TCP    [::1]:6379             [::]:0                 LISTENING       17584
 [wslrelay.exe]

First i would like to say that this was the only thing that helped me to access wsl2 localhost:8080 from mobile...
But now im not using router anymore, only hotspot from my mobile... in theory it should not matter, as outside wsl2 i can open webpack express server running on windows, but not in wsl2... im very tired of this journey!... actually im writing this issue for you to help us, but already installing git to work locally instead wsl2...
Im not sure if the hotspot thing interfered or if it´s just some windows 11 update who knows...

At first stance i´ve tried to stick using only ngrok... but for some reason ngrok doesn´t full reload, i think it reloaded in the past im not sure... (hot false, neither hot true, i use false i prefer full reload)... also the performance of acessing it direcly via localhost seems superior

First of all... thanks for this!

Unfortunately only half my issue is solved. It appears UDP doesn't work. Is that expected?

This project is awesome and could benefit from an open source license. If you have some time, could you select one that makes it easier for contributions? It's entirely possible that Win 11 won't have resolved the network bridging issue, and we'll need a straightforward app like this to continue patching instances.

How to apply a LICENSE file to the repository

Excuse me.Can this work in win 11?

Hello,

Recently I upgraded my WSL2 to latest stable version, and unfortunately I found that WSLHostPatcher no longer works with latest version.

WSL version： 2.0.9.0
Kernel version： 5.15.133.1-1
WSLg version： 1.0.59
MSRDC version： 1.2.4677
Direct3D version： 1.611.1-81528511
DXCore version： 10.0.25131.1002-220531-1700.rs-onecore-base2-hyp
Windows version： 10.0.19044.3693

Although there is no error message, no port can be accessed from remote host.

# WSLHostPatcher.exe
Dll path: C:\Portable Softwares\EXE\WSLHostPatch.dll
Found 5 WSL host

Is there any idea to deal with this?

I'm pretty sure it's something very obvious.. but I don't see the executable anywhere.
Do I have to generate it somehow?
Thanks!

Just wanted to say thank you for this awesome tool. Now I can finally use WSL2 for cross-network server development.

Hi, thanks for this tool!

I'm not exactly sure how to put it in .profile?
Is WSLHostPatcher.exe executed in Powershell/cmd aka "outside" of WSL2 or inside of WSL2?

I have a web server running in WSL2 in ubuntu. I'm using postman in windows GUI. If I try to send a GET request to http://127.0.0.1:3001 it never makes a connection.

However if I use http://localhost:3001 it works just great. Any ideas?

Thanks for the great tool. It works as expected when using a nodejs express server, but when I try to setup a UDP socket in c++ it doesn't seem to work. Is UDP not supported at all with this workaround?

hostpatcher will cause the IP address of all network requests sent to WSL to become localhost.

所有来自远程的请求，其ip地址都变成了localhost

I am trying to use WSLHostPatcher for HomeKit accessory. This utility doesn't work because I need to be able to broadcast Bonjour or CIAO packets from WSL. Is there a way to have this do that or no?

Hi! I tried your solution as it seems the cleanest approach, but so far I haven't had any luck. Maybe you have an idea what might be happening.

sshd is running on WSL2 instance and I tried from the windows host and I can do ssh to linux fine

No luck from other machines on my network though, I disabled the firewall on Windows just in case but still the same

This is the output that I get from netstat, shouldn't this be listening on 0.0.0.0:22

netstat -an | grep :22
  TCP    127.0.0.1:22           0.0.0.0:0              LISTENING
  TCP    [::1]:22               [::]:0                 LISTENING

After reading some of the issues, I wasn't sure where to run the patch, windows or wsl, but it seems that doesn't matter I get the same output, although nothing seems to work

Dll path: C:\bin\WSLHostPatch.dll
Found 2 WSL host
Patched 2

The README says "Run WSLHostPatcher.exe after WSL2 started," but there is no such file (nor any exe) in the repo... not even in the exe folder.

How to install?

I've been using wslhostpatcher successfully for a while to get access to my locally running Rancher-Desktop from an Domain from outside (only for development purposes).

Setup:

• Windows 10 Enterprise
• Rancher Desktop 1.6.2
• WSL 2 1.0

My workflow was:

• start Rancher Desktop
• run wslhostpatcher.exe
• restart Rancher Desktop

Since the last WSL2 update it stopped working, the applications running in Rancher Desktop are no more available from outside.

Unfortunately it is very uncomfortable without wslhostpatcher to make applications available which are running in the WSL2.

Is there any help? Any new version of wslhostpatcher?

I started using this since a month ago. Suddenly our Cybersecurity pinged me mentioned that they received an alert from my machine as they have seen a potential malicious file in my system. I have uninstalled it. Here is the report
