Example:
If 10.180.18.222 is my server's ip address.

# ftp 10.180.18.222
Connected to 10.180.18.222.
220 TomcatServer FTP server (Version 5.60) ready.

GSSAPI accepted as authentication type
GSSAPI error major: Unspecified GSS failure. Minor code may provide more information
GSSAPI error minor: No credentials cache found
GSSAPI error: initializing context
GSSAPI authentication failed
334 Using authentication type KERBEROS_V4; ADAT must follow

Above output shows that ftp is running on 10.180.18.222 .

To Disable the ftp you need to edit gssftp file under
/etc/xinetd.d directory.

You should modify disable parameter to yes.

# cat gssftp
# default: off
# description: The kerberized FTP server accepts FTP connections \
# that can be authenticated with Kerberos 5.
service ftp
{
flags = REUSE
socket_type = stream
wait = no
user = root
server = /usr/kerberos/sbin/ftpd
server_args = -l -a
log_on_failure += USERID
disable = yes
}

Once you have modified the file you should restart xinetd
#/etc/rc.d/init.d/xinetd restart


To check FTP is running or not:

# ftp 10.180.18.222
ftp: connect: Connection refused
