Leginon

Hi Anchi et al.-

I came back after being out of town excited to fix my silly pixel size error (oops). However, some sort of problem had occurred which resulted in me having to restart our K2 and K2 computer.

After doing so, Leginon was unable to load camera settings or take images, although it was still capable of connecting to the K2 computer client.

The issue appears to be with dmsem.py making a connection on the local computer, as the following test fails:

import pyscope.dmsem
k=pyscope.dmsem.GatanK2Counting()

Traceback (most recent call last):
File "<pyshell#1>", line 1, in <module>
k=pyscope.dmsem.GatanK2Counting()
File "C:\Python27\lib\site-packages\pyscope\dmsem.py", line 50, in __init__
self.camera = connect()
File "C:\Python27\lib\site-packages\pyscope\dmsem.py", line 35, in connect
gatansocket.myGS = gatansocket.GatanSocket()
File "C:\Python27\lib\site-packages\pyscope\gatansocket.py", line 139, in __init__
self.connect()
File "C:\Python27\lib\site-packages\pyscope\gatansocket.py", line 175, in connect
self.sock = socket.create_connection(('127.0.0.1',self.port))
File "C:\Python27\lib\socket.py", line 571, in create_connection
raise err
error: [Errno 10061] No connection could be made because the target machine actively refused it

As best I can tell the firewall on the K2 computer is entirely disabled, and it was working correctly before restarting the machine. It seems quite strange that it would still accept network connections (i.e. test1.py test2.py work), but not local connections. The SERIALEMCCD_PORT environment variable is set to 53333, and is read correctly by os.environ.

I was wondering if you had ever seen something similar, and if it is indeed some sort of security setting on the K2 windows computer...

Thanks,
-Greg
