VSFTPD installed, but I can't restart/stop it

Question

I've installed VSFTPD on my VPS running Ubuntu server 10.04. When connecting using FTP clients such as Filezilla it's working perfectly. However when I use my Drupal's native FTP client to update the modules and the core installation my "working" login credentials are not working.

So after searching the internet, there are some configurations that should be changed on "vsftpd.conf" which I followed and those instructions say that I should restart my VSFTPD.

So after trying these commands

sudo /etc/init.d/vsftpd restart
service vsftpd restart

Both results to *respectively

sudo: /etc/init.d/vsftpd: command not found
service vsftpd restart

Then there's another weird thing that went out when trying to find out the problem my self

When I type

ls -l /etc/init.d

It results to

.
.
.
lrwxrwxrwx 1 root root    21 Oct  2 06:29 vsftpd -> /lib/init/upstart-job

What could be wrong?

Any help would be GREATLY appreciated. Thanks in Advance!
