 Posted: Sun Jan 01, 2006 9:28 am Post subject: ntp won't work (address family not supported by protocol) |
 |
|
Following the wiki HowTo for ntp I got stuck pretty early in the process. Ntpdate won't work properly. Using
| Code: |
netselect -s 3 de.pool.ntp.org
|
I found the IP addresses of three German ntp servers to use; my /etc/conf.d/ntp-client now looks like this (comments removed):
| Code: |
NTPCLIENT_CMD="ntpdate"
NTPCLIENT_OPTS=" -b -u 62.206.253.10 80.190.252.238 81.169.136.18"
NTPCLIENT_TIMEOUT=30
|
The -u parameter was in there by default, it is not in the Wiki article and I have tried both versions with the same result. When trying to run the client I get:
| Code: |
/etc/init.d/ntpd-client start
* Setting clock via the NTP client 'ntpdate' ...
/etc/init.d/ntp-client: line 34: 5854 Getötet ${NTPCLIENT_CMD} ${NTPCLIENT_OPTS} >/dev/null
* Failed to set clock
|
('Getötet' means 'killed')
If I run ntpdate with the above parameters or for instance de.pool.ntp.org instead of the IPs, I get
| Code: |
ntpdate -b de.pool.ntp.org
1 Jan 10:20:54 ntpdate[5911]: poll(): nfound = 0, error: Address family not supported by protocol
|
I am using a router to connect to the internet, and it has an in-built firewall, but I have set it to forward port 123, both UDP and TCP, to my internal IP.
Does anyone have an idea what I could try next?

Not needed as long as you use -u.
I would check whether ntpdate (package ntp) was compiled with the right protocol(s).
As a first test, run it with the -4 option to force ipv4 addresses.
Why ever use IP addesses anyhow ?
Just use de.pool.ntp.org as your server; that picks a random one from that pool (as it is intended to be used).
There are over a dozen servers in the pool.

Using de.pool.ntp.org doesn't change the problem. I've tried -4, too, and it still doesn't work; moreover, when I use -6 just to check I get an immediate error:
| Code: |
Error : No address associated with hostname
1 Jan 17:29:21 ntpdate[5944]: can't find host de.pool.ntp.org
1 Jan 17:29:21 ntpdate[5944]: no servers can be used, exiting
|
The original error appears after timeout only.

Does your machine resolve any DNS addresses correctly? Can you ping a remote hostname or use dig to get a dns record

I can ping de.pool.ntp.org ok, and other DNS resolutions work, too - I can use a browser, emerge etc.; though I do have problems with the ftp servers for emerge occasionally and emerge sometimes tries its way through a number of them with timing out. I put that down to holiday traffic ... (?) I've only been on Gentoo for a week, so I don't know whether that's going to be a constant problem. There might be something wrong with my net setup, but not in a way that it is completely broken.
| Code: |
ping de.pool.ntp.org

Have you turned off the port forwarding on your router?
Are you able to run the ntpdate command directly with -d to see if it gives any more data. |

The router does not have an option for turning off port forwarding altogether; you can only open individual ports. The -d parameter doesn't change anything, the error output is still the same.

| Try emerging a masked version of bind (I've happily used both 9.2.5-r6 and 9.3.1-r8 ), and ensure it's emerged with safe CFLAGS. |

I have emerged 9.3.1-r8; no change.

Can't really put 'solved' in the topic line, but using chrony works for me. That's good enough.

ancient thread but i just ran into this issue. in case someone else hits this i had a incomplete /etc/shadow.
running "pwconf" and /etc/init.d/ntpd restart fixed it for me. |
