Dear Jeff,

I encountered a problem.
I tried to run test_2_mac_receive_images.py on Windows 7 , test_2_rpi_send_images.py on Raspberry Pi, but server site no response.

on the Raspberry Pi site, ran "lsof |grep 5555" will show a lots of these messages
python3 658 672 python3 pi 14u IPv4 16265 0t0 TCP 192.168.34.143:54214->192.168.34.93:5555 (SYN_SENT)
python3 658 673 python3 pi 14u IPv4 16265 0t0 TCP 192.168.34.143:54214->192.168.34.93:5555 (SYN_SENT)
python3 658 674 python3 pi 14u IPv4 16265 0t0 TCP 192.168.34.143:54214->192.168.34.93:5555 (SYN_SENT)
python3 658 675 python3 pi 14u IPv4 16265 0t0 TCP 192.168.34.143:54214->192.168.34.93:5555 (SYN_SENT)

on Windows 7 site, ran "netstat -an| grep 5555" , just showed only
TCP 0.0.0.0:5555 0.0.0.0:0 LISTENING

Can you tell what is these problem?

I found out that Anaconda will add an InBound block rule for Python with connections from public networks.

That's the root cause.

I don't use either Windows or Anaconda, so I'm afraid I can't be much help in resolving this. But please continue to add anything you learn if you come up with a solution that works for you. Thanks.

Dear Jeff,
Yes, the solution is to change the inbound block rule to let any connections can go through the port 5555.
After that, everything will be fine.
