i m getting this error in module 3
i have tried all solutions on forum but still it shows this error
i have done “sudo chown root vsftpd_v1.conf” also but still error is there pls help !!!

Aren’t you missing somethin? you should use the binary file and the configuration file.

Please check again your command is right or not google it that on which files we can use ./

i used
sudo ./vsftpd_v1.conf vsftpd_v1
in QBox directory
still the same error

Refer to the synopsis section in this page to understand how to use vsftpd.
