"500 OOPS: vsftpd: refusing to run with writable root inside chroot()" - login failed on Debian

Solution 1:

I searched for it toooooooooo much, and I really mixed up, so I decided to change vsFTPd to SFTP or something else, till I found a link about this bug.

Then I found out this problem was solved in vsFTPd version 3. So I searched how to upgrade it and could find to add the jessie repository to my Debian 7.3 installation and upgrade it so:

echo "deb http://ftp.us.debian.org/debian jessie main contrib non-free" >> /etc/apt/sources.list
aptitude update
aptitude upgrade vsftpd
echo "allow_writeable_chroot=YES" >> /etc/vsftpd.conf
service vsftpd restart

Now it works correctly for me.

Solution 2:

Just add

seccomp_sandbox=NO

to the configuration and restart the service with service vsftpd restart

Then "allow_writeable_chroot=YES" will work also with newer vsFTPd versions (found in 500 OOPS: vsftpd: refusing to run with writable root inside chroot() Keep user jailed).
