Disclaimer: I'm not an expert.
If proftp is being started by inetd (I believe this would be the default) I think it should be as simple as editing /etc/inetd.conf and changing the following lines:
Code:
# Very Secure File Transfer Protocol (FTP) server.
#ftp stream tcp nowait root /usr/sbin/tcpd vsftpd
#
# Professional File Transfer Protocol (FTP) server.
ftp stream tcp nowait root /usr/sbin/tcpd proftpd
#
to this:
Code:
# Very Secure File Transfer Protocol (FTP) server.
ftp stream tcp nowait root /usr/sbin/tcpd vsftpd
#
# Professional File Transfer Protocol (FTP) server.
#ftp stream tcp nowait root /usr/sbin/tcpd proftpd
#
and then running:
Code:
/etc/rc.inetd restart
