is there any way to tell what services can be controlled by xinetd?

this is what i got in my current /etc/xinetd.d/ directory:

chargen cups-lpd daytime-udp echo-udp rsync sgi_fam tftp time-udp
chargen-udp daytime echo ktalk services swat time

Im running fedora core 2. I tried to write a vsftp file in there, contents:

service ftp
{

disable = no
socket_type = stream
wait = no
user = root
server = /usr/sbin/vsftpd
nice = 10

}

I reloaded xinetd, stop vsftp service.. when i ftp to my pc it comes up with this error msg:

[fireice@toys /]$ ftp 192.168.1.2
Connected to 192.168.1.2 (192.168.1.2).
500 OOPS: could not bind listening IPv4 socket

So, I wanna know if its possible to run vsftp under xinetd and how do we know what other services we can run as well...am i even suppose to create a config file like what i did to try run vsftpd? Pls explain...thank you.

make sure in the vsftpd config file you have "listen=NO" if you want to launch it using xinetd instead of standalone.

As to how to find out whether a daemon supports xinetd/inetd, you have to read the documentation.
