I synchronizes with a time server.

218.59.75.203 is an address on the on Shandong Provincial Network in Beijing. It apparently has no time server.

203.181.37.152 is one of the addresses returned by 0.asia.pool.ntp.org.

Code:
#dig 0.asia.pool.ntp.org
lists eight different addresses. All of them are name servers since that is what ntp.org does.

what problem do you exactly mean?? the last post from george?? if so, in my config i also have no opts. ntpd is started as root.

Code:

# /etc/conf.d/ntpd

# Options to pass to the ntpd process
# Most people should leave this line alone ...
# however, if you know what you're doing, feel free to tweak
NTPD_OPTS=""


i have installed 4.2.4_p0 on an amd machine.

Yes, I mean the last post from george. If I add NTPD_OPTS="-u ntp:ntp -s" in /etc/conf.d/ntpd, ntpd can't be start.

Anyone here have the same problem as george?


And anyone here know this error:
# /etc/init.d/ntpd start
* Starting ntpd ... [ ok ]
# ntpq -p
ntpq: read: Connection refused

/etc/ntp.conf:
server pool.ntp.org
logfile /var/log/ntpd.log
driftfile /var/lib/ntp/ntp.drift


Thank you kindly.

hi!

look at the postings above:

Code:

...
error messages:
# /etc/init.d/ntpd start
 * Starting ntpd ...
/usr/sbin/ntpd: invalid option -- u
usage: ntpd [-dSs] [-f file]
 * Failed to start ntpd 
...


the -u option is no longer valid. so u only can add -s to your NTPD_OPTS.

#man ntpd
-u string, --user=string
Run as userid (or userid:groupid).

Specify a user, and optionally a group, to switch to. This option is only
available if the OS supports to run the server without full root privileges.
Currently, this option is supported under NetBSD (configure with --enable-
clockctl ) and Linux (configure with --enable-linuxcaps ).

There is no invalid info?
If -u is invalid, do you know how to run on droproot?

thank you.

Hi snIP3r


I find where's the problem.
In Geoge's setup: net-misc/ntp-4.2.4-r1 USE="caps openntpd ssl -debug -ipv6 -parse-clocks(-selinux)
There is oponntpd in use flags, so the ntpd is openntpd's ntpd not ntp's ntpd.
In openntpd there is no -u option and the config file should be ntpd.conf not ntp.conf.
Openntpd will spawn a process using ntp:ntp user.
So now I just use openntpd, comparing with ntp there are many advantages.

Thank you kindly.
