How to fix 421 unable to read the indexed puredb file error?
421 Unable to read the indexed puredb file (or old format detected) - Try pure-pw mkdb
Have you installed pure-ftpd on your server, but are still receiving an error message despite entering the correct username/password? Here are some solutions.
Wrong config configuration and suggestions.
Open the configuration file with the following code.
nano /etc/pure-ftpd/pure-ftpd.conf
Make sure the following settings are correct in your config file.
TLS 1
PassivePortRange 30000 50000
#PureDB @sysconfigdir@/pureftpd.pdb
PureDB /etc/pure-ftpd/pureftpd.pdb
One of the most common mistakes is that @sysconfigdir@ is perceived by users as a template/syntax/variable, but it is not, you need to make sure that there is a correct file path in this field.
After adjusting these settings, restart pure-ftpd service.
systemctl restart pure-ftpd
We wish you success! 🐧
