How to update port number vsftpd_v1.conf file only showing boolean options not showing numerical options. i used chmod 777 file as well but this operation is not permitted . How to change listen_port to 8081?? tried to change it manually as well by opening the file vsftpd_v1.conf file
use sudo nano <file_name>
@gouravsardana Yes its allowing me to update the file. So i write at the bottom listen_port=8081.But it didn’t change .
also after restarting its showing: Failed to restart vsftpd.service: Interactive authentication required.
