We have one user created let's called it "USER_a" which is used to perform FTP command "get" files from other system into a directory, let's called it "Directory_a". We need the files permission that transferred into "Directory_a" to be change to "644" in order for the group member and others can read it. I have been told this can be done in vsftpd.conf but I have no experience in doing so. So can someone give me some guidance how to start? Because currently the files permission will be "600" when the "get" command complete.

Thank you
