Spurious CFDP transaction finished event when sending a batch of files
-
bpcp leaves a file remnant on remote machine
-
As of 4.1.4, the temporary file only remains if the filestore command did not complete. This happens when a file with the same name already exist in the destination folder. In that case the file is saved as cfdp.x.y where x is the source node number and y is the a monotonically increasing number. The pair x.y is the transaction id. This is not an issue. We believe leaving the file in place, identifiable by the transaction ID is sensible for users who wants to retrieve the file if needed. Closing...
-
Need documentation on Windows Installation Instructions and Dependencies

Windows installation instruction has been added to ION 4.1.3s. Since then ION team is no longer actively supporting Windows. But users are encouraged report compilation and test failures to the GitHub site.

Better control over interactive mode
-
Closing for now. This is tracked under GitHub and will not be address in the near term. We want to better understand the requirements before adding features. The actual human-flight configuration may be simpler or more complex, depending on the human interface design. So we will not commit resource until we are clear. But this is important.

Aditya Rewanshete posted a comment on discussion ION Configuration and Usage
Hello everyone, I am tring to use ION for simulating connectivity between multiple LEO satellite nodes and ground stations. By default ION only accepts range values in light seconds, and assumes that this distance is not changing within 1 light second. Which is very true for Deep space networks, but in the case of LEO satellites (or any satellite network around earth for that matter), the distance is much less and the default assumption of range not changing within one light second does not fit well...
