I am trying to transfer using the below command line.
Both sender and receiver are using the same version
Local FDTVersion [0.26.2-2017-08-08], Remote FDTVersion [0.26.2-2017-08-08]

java -jar fdt.jar -noupdates -nbio -v -p "customport" -c "serverip" -fl "filelist.txt" -d /destination/directory/

See the below in the reciever logs before FDT stops.

I switched to an older version of FDT and it worked like a charm
[0.24.0-2015-12-04]

Worth noting that the source is Linux and the destination is Windows.
Wondering if PR #40 would fix this

I can confirm that PR #40 fixes the issue for transfer port switching to 0. I am running windows for server and client. The current master branch 'as is' does not work for me since the port switches to 0 from the assigned port. Merging PR #40 locally allows it to send files as expected.
