Elsewhere on the forum it was established, that it is not possible to read files longer than 4096 bytes. It’s rather sad, as I need to download and import a file with static dns (/ip dns static add), which is longer than 4096 bytes. On schedule.
I’d like to confirm that there is still no solution to this problem.
I’ll probably have to put up a web service somewhere which will download, and chop the file for me and serve it in smaller chunks. If anyone can think of a better solution, please let me know.
