Access a local port in my Ubuntu VM from the Windows Host

[szlamany]

Wow - I'm way outside my comfort zone.

I created a little SOCKET app with C++ in my Ubuntu VM running on my MS Surface Pro 7 in vmware

I've got a server and client app that runs in the VM properly - just sending a little test response.

How do I allow access to the port inside the linux VM from the Windows side?

I do not have ufw "active" - I just did a "sudo ufw status" and it's inactive.

Thanks! Steve

I can only answer how i do it in VirtualBox (no idea about vmware):
think of it the hosting software (VirtualBox, vmware) is kind of like a router: you want to „forward“ the port of the guest-os to the outside world, the host-os.

IIRC, there should be config-options available in the hosting software.
i remember defining port 5678 to map to port 3306 (MySQL) running in the guest.

hope you understand what i mean

You should be able put the VM on the same network as the host machine. From there you treat the Linux instance as if it were just another physical computer on your network. That basically what I did here for me to be able to connect to the webserver inside the Linux instance. You can see about half way through the video that I compiled the WebServer, copied it to Linux, ran it and just connected to it from a web-browser in the host with no problems.

Niya is right, but there are basically two ways:
what Niya said (same network), which in VirtualBox is called a LAN-Bridge,
or with a NAT-Connection.
It was with the second that i could remap a different port

i‘d look for those two in vmware

Try using a NAT network connection. After obtaining the IP address of the Ubuntu VM, you can access the local port from the Windows host by launching a web browser or any other network application and entering the IP address of the Ubuntu VM along with the port number. For example, if your Ubuntu VM's IP address is 192.168.0.100 and your server application is active on port 8080, you can access it from the Windows host by entering "http://192.168.0.100:8080" in the web interface browser.
