 Posted: Sun Mar 14, 2004 2:44 am Post subject: NTPD: Bug?? |
 |
|
Hello,
After lots of playing around I have got ntpd working: synchs to stratum 2 server and synchs local winxp machines.
I did notice a problem: I dont know if this is a bug or a configuration error.
| Code: |
silent-srvr:> /etc/init.d/ntpd start <---- works fine
silent-srvr:> /etc/init.d/ntpd stop <---- stops fine
silent-srvr:> /etc/init.d/ntpd start <--- fails!!!
|
Same results for:
| Code: |
silent-srvr:> /etc/init.d/ntpd restart <----- stops fine then fails on restart
|
It appears the lock file is not removed when ntpd exits and then ntpd refuses to restart since it finds a lock file...
So to restart I need to :
| Code: |
silent-srvr:> /etc/init.d/ntpd stop
silent-srvr:> rm /var/run/ntpd.pid
silent-srvr:> /etc/init.d/ntpd start
|
Okay.... Whats up? Why is this not working...
In the init.d script it is using start-stop-daemon. I thought this was supposed to automaticly make and remove lock /pid files.
Thanks....
BRENT |

What happen if you comment out NTPCLIENT_CMD?
BTW, are you using 4.2? IME, ntp 4.2 didn't work. I've reverted back to 4.1.1b and it fixed all my problems. |

Im running the following version:
| Code: |
silent-srvr root # ntpd --version
ntpd: ntpd 4.1.2@1.892 Fri Mar 12 23:05:15 PST 2004 (1)
|
Opps... The NTPCLIENT_CMD="ntpdate" came from /etc/conf.d/ntp-client.
I edited previous post to make correct. |

| Do you have a stale ntp process running? Try "killall ntpd" as root. |

It appears that the /etc/init.d/ntpd script is not shutting ntpd down.. The question now would be why?

I think the question is "why is your box running 4 instances of ntpd?"
All my boxes show only ONE process. Can you please run: | Code: | | # /usb/sbin/ntpd -d -n -p /var/run/ntpd.pid -U ntp |
and watch its output? BTW, what does /var/log/ntpd.log says? |

I believe I had four running probably because I didnt realize that when I was running "/etc/init.d/ntpd stop" it wasnt really stopping ntpd. So then I would "rm /var/run/ntpd.pid" and then "/etc/init.d/ntpd start" and would end up with multiple instances.... Sound about right correct?
Now when I do:
| Code: | silent-srvr root # ps aux | grep ntpd
ntp 26933 0.0 0.4 2312 2304 ? SL 12:32 0:00 /usr/bin/ntpd -p /var/run/ntpd.pid -U ntp
silent-srvr root #

It appears to be stopping ok... But it still leaves the ntpd.pid file and then I cannot restart unless I first remove the pid file.
| Code: | silent-srvr bin # /etc/init.d/ntpd stop
* Stopping ntpd... [ ok ]
silent-srvr bin # ps aux | grep ntp
root 14359 0.0 0.0 1512 440 pts/0 S 13:25 0:00 grep ntp
silent-srvr bin # /etc/init.d/ntpd start
* Starting ntpd...
* Failed to start ntpd [ !! ]
silent-srvr bin # rm /var/run/ntpd.pid
silent-srvr bin # /etc/init.d/ntpd start
* Starting ntpd... [ ok ]
silent-srvr bin # ps aux | grep ntp
ntp 12603 0.0 0.4 2312 2304 ? SL 13:26 0:00 /usr/bin/ntpd -p /var/run/ntpd.pid -U ntp
root 3149 0.0 0.0 1552 440 pts/0 S 13:26 0:00 grep ntp
silent-srvr bin #

For what it's worth, I'm having exactly the same problem.  |

Hi all
I just emerged ntp and I got exactly the same problem for restarting
Does this mean that next time I reboot ntp will not start? |
