Flaskr didn't pose any significant issues, for which I am grateful.
My Ubuntu instance is a VM running on the iMac in my office. In class and from home, I remote into the instance via ssh or VNC.
There are a number of steps to get there:
1) connect via the VPN
2) ssh -XC to the instance
3) run flaskr in the background - (so I don't need to open another window) via 'nohup python flaskr.py &'
tonight I got an error:
socket.error: [Errno 98] Address already in use
Let's troubleshoot:
$ sudo netstat -ap | grep 5000
[sudo] password for pcolar:
tcp 0 0 localhost:5000 *:* LISTEN 21798/python
Oops, my detached process was still running from Monday.
sudo kill 21798
the 'sudo' was not strictly needed, since the process was running under my ID.
OK, back to the assignment!
