Is it possible to have a ethernet port and open a socket port where a PC can send/receive a stream of data with the ARM processor?

How should I do this? Do you have a tutorial/sample for me?

Thank you

You need a TCP/IP protocol stack. A lightweight one like LwIP might suffice. Google around a bit and find one that fits your needs/costs.

Do you think I can setup a socket and send/receive stream of strings data using that?

Thank you

I can't speak to your skills to implement/port code, but most of the STM32 Ethernet TCP/IP examples come with a simple HTTP web server which clearly demonstrate an ability to send/receive data via sockets. The professionally written/licensed solutions are likely to come with more clean/clear examples.

Look for one of the many STM32 Development Kits with Ethernet, and demo applications.

How familiar are you with socket programming in general? For example have to implemented a HTTP client/server, POP or SMTP?

Here's an OS example of FTP
