Hi my mbp is showing under system profiler that the EFI file system is MS-DOS FAT 32 . is that normal ??

Also in memory is system profiler its displaying ecc memory is turned off is that normal for a 2017/MBP

And wondering how I turn off passive FTP ?
 
On GPT . Apple usually adds an EFI partition. It's usually empty and used for things like bootcamp usually to save the windows bootloader etc AFAIK.

And ECC memory . I don't think consumer grade items have ECC memory in them . Atleast for 2017 MBP

And passive ftp idk. Never heard of it. Need someone else to chip in on that part..

basically if you choose active mode, then the data channel will normally be FTP port 20. But if you choose passivemode, then the port that will be used will be a random port.

open a terminal and open an ftp connection:

ftp what.ever.adress.the.ftp.server.has

after establihing the connection type passive inside the ftp session. You should see something like below. Repeating the passive command turns the mode off.

ftp> passive Passive mode on. ftp> ls 550 Permission denied. Passive mode refused. ftp> passive Passive mode off. ftp> ls 200 PORT command successful. Consider using PASV. 150 Here comes the directory listing. -rw-rw-r-- 1 503 503 0 Oct 30 2020 files1 -rw-rw-r-- 1 503 503 0 Oct 30 2020 files10 -rw-rw-r-- 1 503 503 0 Oct 30 2020files2 226 Directory send OK. ftp>

If I remember right, Filezilla or Cyberduck provide a switch in their interface.

I don't actually know address it is connecting to. Although net stats showing some strange stuff.
System profile is showing that it's on
Can I turn it off without connecting to a ftp server. ?
 
you want to deactivate ftp in general? What MacOS are you running?
Active or passive command switches the mode of/for a ftp connection. It’s an “old” protocol, if anything one should use sftp.

correct. Big Sur , so how do i deactivate it in general. ? do pkg managers ie like homebrew let you remove mac system packages ? how do you completely remove stuff on mac like you do in linux ?

You cannot remove macOs system packages. You cannot make macOs into Linux. If you want to customize the kernel and remove everything and get a 100mb install like you can on Linux - use Linux.

Paste a screenshot of your system profile where it shows FTP on in passive mode.

Yeah, makes sense to use the Mac for stuff like Adobe's software. It's just never going to be like Linux, so no point expecting that. Just as Linux is not good at some stuff - horses for courses.

AFAIK the ftp server functionality is not included with Big Sur (actually it’s gone since High Sierra/Mojave and it was pulled to instead emphasize SFTP usage). Anyway, an outgoing sftp/ftp is something you (or some program you have installed) have to initiate.
If your find that on your system an unwanted outgoing passive ftp connection is initiated (there are various ways to do that e.g. from terminal ps -e | grep ftp; modify the grep search according your needs or use e.g. less to display and scroll trough all active processes), first step then would be to kill the process (having obtained the process id from the previous command use kill process-ID).
Theren a next step I would try to identify which program from your startup items initiates it.
If you have installed programs and other packages using Homebrew, well there is an additional source to check for processes called on startup.
Of course you could just block port 20, so passive ftp connections will not work, here is some guide on how to use pfctl.

What you want to achieve and why?
