At script writing

I have doubt about script writing that in one of the vsftpd_versions it takes lot time to transfer file so do I have to wait for that or terminate that transfer?

At all times during module 4 you need to remember that some versions are faulty. Therefore, what to do in situations like these is up to you, keeping in mind the aforementioned fact.

each version acts differently, Some take less time to transfer and some take more time to transfer
