I would like to know that how to delete a user in proftpd created with command:
adduser username-GroupManager --in group ftpusers --home /home/username/somewhere/
I have not found anything on the web.
vi /servers/proftpd/etc/passwd
shift + /meteo - search file for user meteo
dd - delete line
esc + !wq + enter
I hope this helps.
