Software :: Slackware 13 - NTPD Sets Its STRATA Too High
Mar 25, 2010
I have recently installed Slackware 13 (64bit) (Kernel 2.6.29.6) on an Acer Veriton M series with AMD Athlon cpu. I have started ntpd server and from it's log file it seems to be synchronising to each of the three stratum 2 servers specified in the ntp.conf file.

25 Mar 18:33:08 ntpd[4542]: synchronized to 130.88.200.4, stratum 2

25 Mar 18:58:57 ntpd[4542]: time reset +2.147508 s
If I invoke ntpdate from another linux machine, that ntpdate reports that the stratum of the ntpd server is too high and won't use it.

I have run ntpd on another platform with Slackware 12 (32bit) and never had any problems.

I used Ubuntu 10.10 (64 bit) on IMac i7. As far as, I remember, after installing Pulse-Audio Equalizer, for each restart of the system, after login screen, system sets volume to maximum value. What can I do?

I'd like to get the 13.0 "synchronized to <time server>, stratum <stratum>" messages back on 13.1.
- On 13.0, running ntpd 4.2.4p8, reassuring messages appeared in /var/log/messages like "synchronized to 211.233.84.186, stratum 2".
- On 13.1, running ntpd 4.2.6p1, there are no messages in /var/log/messages to confirm that time is being synchronised.
rc.ntpd on both starts ntpd with the same options. /etc/ntp.conf is identical on both, a "get it working and then make it secure" version:
Code:
cat /etc/ntp.conf | grep -E -v '^$|^#' cat /etc/ntp.conf | grep -E -v '^$|^#'
server in.pool.ntp.org
server asia.pool.ntp.org
server 127.127.1.0
fudge 127.127.1.0 stratum 10
driftfile /etc/ntp/drift
According to Linux Home Networking, synchronization can be checked using ntpq -p. This shows synchronization is working. I would prefer to see that confirmation in /var/log/messages without having to run a command manually to check it. How to get the old messages back?

When I installed Slackware, I deselected a few software sets like KDE and TCL, but now I would like to install KDE (btw, what is TCL for? Is it something important that I should have installed, or is it something like "if you don't know, you don't need it"?). What would be the best way to install the KDE software set and even have a menu to deselect a few packages I know I won't use?produces a list of kde packages (including the kde language packages), but I don't know if that's everything in the kde set. It seems like it's not, since it's transcending the software set boundaries to provide options for the internationalization packages, too.

During Slackware 13.1 setup, I chose the hostname stella-sl2. This hostname is also the one that the system is displaying before I configured network access. After configuring wired network access to my Apple Time Capsule, my hostname suddenly changed to INTERFACE='eth0'. As a result I'm noticing some very strange things, like the login prompt which has become "INTERFACE='eth0' login: ".
After configuring wireless network access to the Time Capsule, the hostname changed to "INTERFACE='wlan0'". Note that, during boot, wlan0 is brought up AFTER eth0.
Also strange is this:
bash-4.1$ cat /etc/HOSTNAME
INTERFACE='eth0'.DNSSERVERS='10.0.1.1'
bash-4.1$ /bin/hostname
INTERFACE='wlan0'
bash-4.1$
Until now, it was only a minor annoyance, it didn't prevent anything from happening, internet connection was not affected. But now I'm configuring sendmail which needs to talk to a relay SMTP server, and sendmail "HELO"'s itself using the bogus hostname:
>>> HELO INTERFACE='wlan0'
<<< 501 HELO requires valid address
554 5.0.0 Service unavailable
Probably this is caused by the Time Capsule not adhering to standards. However, the Time Capsule's firmware is the latest version, so I cannot fix this. Is there a way to prevent dhcp from changing the hostname? How can I make sure that the hostname that I configured during setup remains active?

For some reason after I close firefox , firefox-bin keeps running and it eats more cpu than when firefox was open, a lot more. Same thing with seamonkey, seamonkey-bin keeps running after it is closed.
Attached are two pictures ,
1) While firefox is running: notice the low CPU usage
2) Firefox closed, CPU is almost 50%

My laptop has a very high consumption when running on idle (I mean nothing that write on the disk or video etc..). I read on lenovo forums that people could get 10-12W and I can hardly get lower than 20W. My cpufreq is set to powersave and my cpus are always at the lowest scale.
configure my laptop to save some power. It used to last almost 7h on battery (sadly I don't remember the consumption) on Ubuntu and now it can barely last more than 3h with slackware.
My config is:
T400 intel duo core 3,06ghz
14.1" TFT display with 1440x900 (WXGA+) resolution with LED backlight
Switchable Graphics with Intel GMA 4500MHD and ATI Mobility Radeon HD 3470 (256 MB)
320GB 7200rpm 2.5" SATA HDD
Intel Wifi Link 5300 (AGN)
9 cells battery

I'm running Slackware 13 with a custom kernel based off of 2.6.32.3. I tend to leave my system on 24/7, as well as my web browser. Originally it was Firefox and now it is Google's Chrome. Usually about a day of leaving the web browser open my HD activity spikes so high that I can barely do anything on the system until I kill the web browser. This has been happening with both Firefox AND Chrome! As soon as the browser processes are killed, the system returns back to normal.

Kernel 2.6.21.5, slackware 12.0
When you do 'man bash', you'll see some words are highlighted. I'll say that the video card has used high intesity in these instances. How do I disable this video card capability? Can this only be done by recompiling the kernel? Of course, I am talking about the text consoles, i.e., the video card in text mode.

I am rebuilding / updating my internal server. It is strange to me that 11.0 will not install on this ASUS M3A78 MB but 11.2 will go through. I am setting up the ntp server and run into new things, ntpdate is not used anymore so you have this long string : sntp -P no -r pool.ntp.org which does the same thing or a couple of other calls that may work. It seems that pool.ntp.org will not work however so I switched to another time server.
pool.ntp.org does work on 11.0 however, it still uses ntpdate atm.
I can use ntpdate to my server from other clients and get the time but I can't use Yast to set it up, it hangs (or maybe it will eventually time out) when you test the server in the gui tool. rcntp ntptimeset comes back with no server reached on the ntp server machine so I am not confident that it will auto update itself, which I think is an issue, the server will not respond to client queries after a day or two.

I have a Windows 2003 server that runs a Win32 time server which synchronizes with off site time sources. I have a CentOS 5.4 server which I just configured and installed NTP on. For some reason, I keep getting time discrepancies even after the server is (apparently) synching with my local NTP server on the Windows box.
Hwclock is set to UTC true/etc/localtime is properly symlinked to appropriate /usr/share/zoneinfo fileNTPD is setup as a service which loads on startupNTP.conf is configured to only retrieve from my local Windows 2003 time serverntpq -p seems to verify that the system is indeed synching up properlyThe problem is, whenever I run the 'date' command it is displaying my system time in (presumably) UTC. That is, even though my the CentOS box appears to be synching up to the local time, it's not translating it into my proper time zone. Consequently, the date is always at -6 hours from the actual local time. It was my understanding that the hwclock is fine to remain at UTC as ntpd should be synching with my local Windows 2003 time server periodically and updating it, and the system time should be getting translated to my localtime.
what I do, after rebooting the box the hwclock and system clock display the improper time.Maybe I just have a fundamental misunderstanding of how this is supposed to operate.Update: I'm not sure why, but after I commented out the other servers and added a fudge declaration for my internal server and rebooted, everything is working as it should and the time is correct.I'm still not really sure if it was adding the "fudge <hostname> stratum 2" declaration that corrected things, or commenting out the additional hosts, so I'll leave this open if anyone cares to comment or contribute.

I can compile and run ntpd 4.2.6p2, but after a while the reach indicator falls back from 377 to 0 and then the ntpd is in an unsynced state for a while. So far I haven't seen any indication why we have this.

I am trying to synchronize the time of my VM server with ntpd. I have the following configuration. And in the /etc/ntp.conf, I have the following line:
restrict default ignore
restrict 127.0.0.1.
server time1.server
server time2.server
Whenever I have this line, the erver is not able to synchronize its time... So far as I understood, this line prevents other servers using this machine as a time server. And the second line says to allow localhost to use as time server. But why do I need to use its own time server when I have specified to use time1.server and time2.server ? ( firewall for tcp and udp ports 123 is open)
However, when I replace the first line of the configuration with the following line, it works. restrict default kod nomodify notrap noquery But with this, i am allowing other servers to use this server a ntp (which I wouldn't like to). Why this machine tries to use ntp server of its own (to snyc time) and why it is not working though i have the entry "restrict 127.0.0.1" ??

I have a problem with a server with os Linux RedHat Enterprise AS 4.7:
when the server boots both ntpd and rpc.statd fail to start.
looking into /var/log/messages I found:
and
For ntp, when the server completed the boot process, altough it seems ntpd started, no external server is used for syncronization. The rpc.statd does not start at all and it doesn't appear if I issue a rpcinfo -p
The strange thing is that at this point if I manually start or restart /etc/init.d/ntpd and /etc/init.d/nfslock both services start with no errors. Another strange thing is the timestamp for messages into /var/log/messages. How could it be possible to have a line with a certain timestamp and the following with a timestamp 30 seconds before?
The kernel version in use is 2.6.9-55.0.12.ELsmp #1 SMP x86_64

Can I do this with Ubuntu's software raid?

I'm trying to sync my clock. I think I would like to do this by the "ntpd" daemon running. I think it should start up on boot, but it doesn't.
I have the following in my /var/log/syslog:
Jul 18 23:44:14 neo ntpd[1780]: ntpd 4.2.6p2@1.2194-o Sun Oct 17 13:45:13 UTC 2010 (1)
Jul 18 23:44:14 neo ntpd[1781]: proto: precision = 0.634 usec
Jul 18 23:44:14 neo ntpd[1781]: unable to bind to wildcard address 0.0.0.0 - another process may be running - EXITING
Jul 18 23:44:14 neo ntpdate[1194]: step time server 72.26.125.125 offset -0.505108 sec
Other posts say if ntpd and ntpdate run too close together, they cause one to think the other is locking a resource. It works to type "ntpdate pool.ntp.org" to manually update the clock. My Debian version is squeeze (6.0.2)
It works to start the ntpd daemon manually:
... sudo /etc/init.d/ntp start
... Starting NTP server: ntpd.

I am having a situation with an NTPD server.
Code:
remote refid st t when poll reach delay offset jitter
plesk2.datacent .INIT. 16 u - 64 0 0.000 0.000 0.000
91.198.87.118.b .INIT. 16 u - 64 0 0.000 0.000 0.000

178-26-105-100- .INIT. 16 u - 64 0 0.000 0.000 0.000
and it remains so no matter how long I wait...
Hoping to get better results with ntpdate, I stopped NTPS and tried :
Code:
# ntpdate ntp.skynet.be
29 Mar 09:12:26 ntpdate[4715]: no server suitable for synchronization found
# ntpdate -ud ntp.skynet.be
29 Mar 09:14:02 ntpdate[4814]: ntpdate 4.2.4p4@1.1520-o Sun Nov 22 16:14:35 UTC 2009 (1)
transmit(195.13.23.5)
receive(195.13.23.5) .....
I am running Debian Lenny 64b, and every packages are totally updated. I have 25 identical servers. And there is just one giving me this problem. From what I see, it is not a connection/FW issue since ntpdate get replies from the ntp server (ntp.skynet.be is my isp's stratum 2 ntp server).
