RFC 868 udp 37 time-udp

gpl · 03-30-2005, 01:33 PM

hi , I'm using SuSe 9.0 linux and I have some problems starting eey /etc/xinedt.d/time-udp service , I have configured this file as you can see below :

# default: off
# description: An RFC 868 time server. This is the udp version.

service time
{
type = INTERNAL UNLISTED
id = time-dgram
socket_type = dgram
protocol = udp
user = root
wait = no
disable = no
port = 37
}

is this a correct way or I have still to make some changes , on this way when I try to start this service i got this message :

gpl:/etc/xinetd.d # /etc/xinetd.d/time-udp start
/etc/xinetd.d/time-udp: line 4: service: command not found
/etc/xinetd.d/time-udp: line 6: type: =: not found
/etc/xinetd.d/time-udp: line 6: type: INTERNAL: not found
/etc/xinetd.d/time-udp: line 6: type: UNLISTED: not found
Try `id --help' for more information.
/etc/xinetd.d/time-udp: line 8: socket_type: command not found
/etc/xinetd.d/time-udp: line 9: protocol: command not found
/etc/xinetd.d/time-udp: line 10: user: command not found
/etc/xinetd.d/time-udp: line 11: wait: `=': not a pid or valid job spec
/etc/xinetd.d/time-udp: line 11: wait: `no': not a pid or valid job spec
disable: Operation failed: client-error-not-found
/etc/xinetd.d/time-udp: line 13: port: command not found

Thanks in advance

This file isn't an executable startup script, it is a config file for xinetd, which is an internet superdaemon that starts up other services when they are needed. Xinetd is always running on your computer, your next step should be to tell it to use the script you made to start the time server when it is needed.

What you should do is once you have your /etc/xinedt.d/time-udp file set up you need to open the config file for xinetd (I think it should just be /etc/xinetd.conf?) and set the lines for time-udp. I don't have a SUSE based distro to look at for an example, but my Slackware inetd.conf has a line:

Code:

time    dgram   udp     wait    root    internal

Yours will look somewhat similar, it's possible to find the exact syntax by examining other entries in the file or looking at:

Code:

man xinetd.conf

Once you have the config file for xinetd set up, you simply need to restart the xinetd service. There are likely specific instructions for this at the top of the configuration file, but if not you can:

Code:

ps -ef | grep xinetd
kill -HUP {PID number of the xinetd service from the ps command above}

first of all thanks a lot , after I've posted these problem I saw that this file isn't executable cuz i got a message like "bad format file not execute" , but I wanna ask you a questions for xinetd.conf file right now i have in this condition:

#
# xinetd.conf
#
# Copyright (c) 1998-2001 SuSE GmbH Nuernberg, Germany.
# Copyright (c) 2002 SuSE Linux AG, Nuernberg, Germany.
#

defaults
{
log_type = FILE /var/log/xinetd.log
log_on_success = HOST EXIT DURATION
log_on_failure = HOST ATTEMPT
# only_form = localhost
instances = 30
cps = 50 10

#
# The specification of an interface is interesting, if we are on a firewall.
# For example, if you only want to provide services from an internal
# network interface, you may specify your internal interfaces IP-Address.
#
# interface = 127.0.0.1

and you've told me as far as I understood to edit these lines :

code:

time dgram udp wait root internal

if so , should I delete first the lines which are currently in xinetd.conf or I should put them below or my questions has not to do with it : D

and for the end I can see now with netstat -uln the port udp 37

thanks again
