  • Probable problems

    Error uploading file:

    permission denied

    1. Consider whether it's selinux or not. Try disabling selinux
    2. Maybe the folder of ftp does not have write permission, confirm the permission of the directory
    3. Change the permissions in the configuration file to YES (refer to the configuration file above)

    Could not create file

    Specify file name: put/home/user/share/Kvm.mdHome/eric/tmp/Kvm.md
