Typically occurs when a user logs on. It means that the user's root directory does not exist.

Check the user carefully to see if the corresponding role is configured. It is obviously problematic if the role does not exist. Then check the FTP root settings in its corresponding role to see if the path that is filled in is present on the FTP server. If there is generally no problem. Pay attention to three points:

1 After you modify the role settings to restart the SERVU will not take effect.

2 If the path is on an NTFS-formatted disk, make sure that the FTP server has access to the path.

3 If the local Directory security key is set. The path must be within the path set by the security directory.

10, Permission denied

Typically, the permissions for the path access rule are not set correctly, first check the user's role name, and then check the settings of the role to see if the group number for the path access rule is set. Then check the path Access rule group for the corresponding group number to see if you added access rights to the FTP root directory. Sometimes you can try the English path name because of the database cause of the Chinese character error. Note Modifying these settings requires restarting the serv-u.

The above mainly introduced serv-u and cuteftp common problem solution, I hope to help you solve the FTP problem you are encountering.
