• Ubuntu Server

sudo apt install 'vsftpd'

• 990/tcp is for FTPS

sudo ufw allow '20'/'tcp' && sudo ufw allow '21'/'tcp' && sudo ufw allow '40000':'50000'/'tcp'

sudo systemctl enable 'vsftpd' --now

sudo -e '/etc/vsftpd.conf' && sudo systemctl restart 'vsftpd'

• Be sure to get the PARTUUID towards the end of the line, and not UUID

sudo blkid

• Change the x in PARTLABEL=
• This expects 1 drive each with a XFS partition

sudo mkdir -p '/srv/ftp/nas1' && sudo -e '/etc/fstab'

# NAS
PARTUUID=x /srv/ftp/nas1 xfs defaults 0 2

sudo mount --all && sudo systemctl daemon-reload && sync

sudo chown --recursive 'espionage724':'espionage724' '/srv/ftp/nas1' && sync

• 664 makes sense here, but FileZilla is unable to traverse directories. TODO: Figure this out

sudo chmod --recursive '774' '/srv/ftp/nas1' && sync
