I just installed VSFTPD on my Ubuntu system, but it doesn't seem to work properly.
In the config file i only changed the "local_enable", "write_enable" and "listen" to YES.
When I use "netstat -tanp" or similar commands they only show me "22:sshd" but nothing on port 21.
I tried restarting VSFTPD and i tried restarting my whole VPS. Reinstalling VSFTPD didn't help either.
The weird thing was: Before i restarted my VPS for the first time it was listening on IPv6 Port21, but now it doesn't even listen on that anymore.
I tried everything that google told me but nothing works. It's a fresh installation of ubuntu 16.04.4, and vsftpd is version 3.0.3
(when i try to just type "vsftpd" into my console, it tells me "500 OOPS: ruin two copies of vsftpd for IPv4 and IPv6)
TL;DR: VSFTPD not listening on Port21, any tips why?
