openntpd: sendto permission denied

[Bateleur]

Hi,

I just installed and configured openntpd and the daemon is complaining:

ntpd[1040]: sendto permission denied

Note that my system time has been updated correctly for Summer time and I did not configure openntpd to listen to port 123. My /usr/local/etc/ntpd.conf file looks like this:

# sample ntpd configuration file, see ntpd.conf(5)

# Addresses to listen on (ntpd does not listen by default)
#listen on *

# sync to a single server
#server ntp.example.org

# use a random selection of NTP Pool Time Servers
# see http://support.ntp.org/bin/view/Servers/NTPPoolServers
#servers pool.ntp.org
server 0.ca.pool.ntp.org
server 1.ca.pool.ntp.org
server 2.ca.pool.ntp.org
server 3.ca.pool.ntp.org

Is there a permission I need to set or changes I need to make to my config file?

Thanks!

Check firewall usually its firewall's rules.

Hi!

Ok, it would seem the firewall is causing the error. What port (UDP vs TCP) and port number does OpenNTPD use?

Cheers!

123.

[od@meh ~]$ more /etc/services | grep ntp
nntp		119/tcp	   usenet	#Network News Transfer Protocol
nntp		119/udp	   usenet	#Network News Transfer Protocol
[B]ntp		123/tcp	   #Network Time Protocol
ntp		123/udp	   #Network Time Protocol[/B]
nntps		563/tcp	   snntp	#nntp protocol over TLS/SSL
nntps		563/udp	   snntp	#nntp protocol over TLS/SSL
sntp-heartbeat	580/tcp
sntp-heartbeat	580/udp

Only udp/123 is in actual use for ntp.

Thanks to all!

There was a typo in my firewall rule file at the line enabling udp 123. I fixed it and things work now.
