One thing you could do is to apply von Neumann de-biasing to convert a
string of output bits from your biased PRNG to an unbiased string, and
test the de-biased output. If such tests pass I don't know that you
can be satisfied thaty your biased PRNG is close to a theorieical
biased random bit stre

I tried the written Python code but it needs to insert a username and
password so it's a different service than TFTP but maybe there's also a
code to do it in Python! ;

But, is it that difficult on doing this simple thing?

It's a whole different protocol. TFTP is simplified to the point it
will fit on embedded devices which don't need security (the assumption
being that one has the embedded device physically present, FTP assumes
distributed networks).

I never used TFTP so
The Python code you showed was implementing an FTP server. That's a
completely different protocol from TFTP. There are TFTP
implementations for Pythong. This one works well:

I didn't know the difference of FTP and TFTP so... I thought TFTP was
just a FTP witho

Hi there
I might shortly be posting about a specific issue with imaplib/poplib,
but, thought would first introduce myself.
I am 100% blind, but, among other forms of assistive technology
software, I use windows PC's with the NVDA screenreader, which itself is
written in python, but, beside
