OpenWRT: ftp installation and configuration (vsftpd)

1 open holes in the firewall

Use OpenWRT's web interface (luci): open tcp:20 and tcp:21 for plain old unencrypted ftp.

2 install vsftpd

opkg update
opkg install vsftpd

3 create the ftp directory

mkdir -p /home/ftp_user/storage
chown ftp_user /home/ftp_user/storage

Note: Don't chown the ftp_user dir, because later we will jail the user.

4 add the user to the system

Add a user by editing /etc/passwd, useradd doesn't add a shell, so don't use it.

"/bin/false" - no ssh login possible

ftp_user:x:1000:55::/home/ftp_user:/bin/false

then

passwd ftp_user

to change the password of that user

5 configure vsftpd

Config, add these to /etc/vsftpd.conf, so the anon user points to the right location

anonymous_enable=YES
anon_root=/home/ftp_user/

6 jail the user

chroot_local_user=YES

7 start and enable

to start and make it autostart at boot:

/etc/init.d/vsftpd start
/etc/init.d/vsftpd enable

Basically OpenWRT has issues in terms of scripts and commands, but it's amazing how many things are already implemented.
