vsftpd: 500 OOPS: vsftpd: refusing to run with writable root inside chroot () error solution
Since 2.3.5, vsftpd has enhanced security checks. If the user is restricted to its home directory, then the user’s home directory Can no longer have write permissions! If the check finds that there is still write permission, the error will be reported.
Use the command chmod aw /home/user to remove the write permission of the user's home directory. Be careful to replace the directory with your own. Or add in the configuration file of vsftpd:
allow_writeable_chroot=YES
The source of the following figure: vsftpd configuration: detailed explanation
of chroot_local_user and chroot_list_enable Access control to the corresponding IP:
tcp_wrappers=YES
/etc/hosts.allow
Access to users:
# You may specify an explicit list of local users to chroot() to their home
# directory. If chroot_local_user is YES, then this list becomes a list of
# users to NOT chroot().
# (Warning! chroot'ing can be very dangerous. If using chroot, make sure that
# the user does not have write access to the top level directory within the
# chroot)
chroot_local_user=YES
#chroot_list_enable=YES
# (default follows)
#chroot_list_file=/etc/vsftpd/vsftpd.chroot_list
Error: such as: vsftpd: 500 OOPS: bad bool value in config file for:. . . .
The reason is that there are more spaces at the end of the configuration file line.
