Sometimes QNAP changes file owner to
admin:administ (actually to
admin user in
administrators group) which may cause some troubles on certain FTP operations when you're logged in to QNAP's FTP server with user different than
admin (using this user to operate on FTP is a quite great mistake and you should always use other, less privileged user for this).
chown command you can easily fix this.
General command pattern is:
chown [username]:[group] [filename]
chown guest:everyone temp.file chown trejder:everyone temp.file chown wife:family temp.file
You can use wildcards instead of filename:
chown wife:family *
Above will change file owner of every file in current directory to
wife user and
You can also use
-R switch to change all files in current directory and recursively all files and folders in all folders below it:
chown -R trejder:everyone *
List of all current users and groups is in
/etc/group file which you can list by calling:
Similar list is also in QNAP's Control Panel, in Privilege Settings > Users and Privilege Settings > User Groups.
