Disable FTP Service.

This can be done by loging into the server or any other machine connected to server.All you need to do is type a command called.


If is my server's ip address.

# ftp
Connected to
220 TomcatServer FTP server (Version 5.60) ready.
334 Using authentication type GSSAPI; ADAT must follow
GSSAPI accepted as authentication type
GSSAPI error major: Unspecified GSS failure. Minor code may provide more information

GSSAPI error: initializing context
GSSAPI authentication failed

Name (

Above output shows that ftp is running on .

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
ftp: connect: Connection refused
