NTP on Netra X1
NTP can't synchronize some of my Netra's X1.
It seems that there is an hardware problem.
There is an interesting thread there :

<<The behavior you observe is exactly what happens with the Blade 100 and also with some Ultra 10s. It has nothing to do with NTPv4. There are at least two bug reports to Sun, one of them from here, that point out a 1000-PPM frequency error in the clock frequency of these machines. A patch is apparently in the works, but for now there is nothing we can do about it.>>
This answer comes from NTP's house, udel.edu.
Any patches available ? I can't have a DNS primary server which lose 10 seconds/day.
Someone has run into the same problem ?
tnx.
s.
I'm planning on driving down to the server and simply trying a few things to see if anything looks like its going to work. Is there any way to determine ahead of time if it can be booted from USB, and if not, how would I go about attempting to boot it from a USB drive once I'm there? Something like 'boot /dev/sdb' from the ok prompt in lom? I'm going to take an old IDE CDROM there as well, how would I get it to boot from that?
At this point its looking like this thing may become a fancy paperweight. I don't understand the design decision to not at least put a CD/DVD ROM in it.

Xntpd on Solaris 10 gets synchronised with a higher stratum NTP server
The Solaris 10 machine has the following configuration in etc/inet/ntp.conf
server 10.24.179.33 prefer
server 127.127.1.0
fudge 127.127.1.0 stratum 8
The Linux Fedora Core 4 test machine(10.24.179.33 ) configured as NTP server running ntpd V4 has the following configuration
server 127.127.1.0
fudge 127.127.1.0 stratum 10
The solaris 10 xntpd get synchronised to Linux NTP server even though it is at a higher stratum level.
# ntpq -p
remote refid st t when poll reach delay offset disp
==============================================================================
*10.24.179.33 LOCAL(0) 11 u 18 64 77 2.04 0.084 376.68
LOCAL(0) LOCAL(0) 8 l 17 64 77 0.00 0.000 385.01
The expectation was the solaris machine should not consider the server at a higher stratum level(11) for synchronistation. It should have got synchronised to the Local clock which is at stratum level 8.I now tried waiting for an hour, but the xntpd id still synchronised to the higher stratum clock from the NTP server 10.24.179.33. Please verify the logs below.
Does the prefer keyword in line "server 10.24.179.33 prefer" has anything to do with this behaviour ?
What does the RFC1305 say on process of selecting a synchronisation source ?
My understanding was that xntpd should not be synchornising with a higher stratum clock from the NTP server (which is at stratum 11) when it already has as another server(here the local clock) which is at a lower stratum (we have simulated this by fudging the local clock to stratum 8).
Please correct me on this.
You have mentioned that "Stratum number is not absolute for choosing a clock. A higher stratum may be preferred in some situations."
Could you explain me more on these situations and I also want to know the rules used by xntpd to choose a clock?
Or you could provide any links where I can read more on this aspect.

# @(#)rules 1.12 94/07/27 SMI
# The rules file is a text file used to create the rules.ok file for
# a custom JumpStart installation. The rules file is a lookup table
# consisting of one or more rules that define matches between system
# attributes and profiles.
# This example rules file contains:
# o syntax of a rule used in the rules file
# o rule_keyword and rule_value descriptions
# o rule examples
# See the installation manual for a complete description of the rules file.
# RULE SYNTAX:
# [!]rule_keyword rule_value [&& [!]rule_keyword rule_value]... begin profile fi
# nish
# "[ ]" indicates an optional expression or field
# "..." indicates the preceding expression may be repeated
# "&&" used to "logically AND" rule_keyword and rule_value pairs together
# "!" indicates negation of the following rule_keyword
# rule_keyword a predefined keyword that describes a general system
# attribute. It is used with the rule_value to match a
# system with the same attribute to a profile.
# rule_value a value that provides the specific system attribute
# for the corresponding rule_keyword. A rule_value can
# be text or a range of values (NN-MM).
# To match a range of values, a system's value must be
# greater than or equal to NN and less than or equal to MM.
# begin a file name of an optional Bourne shell script

# Notes:
# 1. You can add comments after the pound sign (#) anywhere on a line.
# 2. Rules are matched in descending order: first rule through the last rule.
# 3. Rules can be continued to a new line by using the backslash (\) before

It seems to me that you have not created a proper sysidcfg file. From your post, it looks to me like your sysidcfg contains no entries. This is why it prompts you to enter the kernel path. Look on docs.sun.com for a guide to creating the sysidcfg file . -
NTP sets SMB clients to wrong time
Hi
The Server (Mac OS 10.6 server) is set as a time server for the domain but from yesterday reset most of the Windows clients that logged on via SMB to about 3/4s hr fast with the result that IP address's were dropped (Lease expired) and software relying on a network connection failed, time stamps of saved files were wrong and emails had the wrong time. In one case the month was changed to October so the guy went on holiday! Seriously, this is a big problem.
I've tried resetting the time locale, NTP time server and got rid of "LocalTime" which was a folder instead of a simlink but clients are still reporting time anomalies.
Thanksntp isn't particularly related to smb/cifs/samba, nor to dhcp, and ntp doesn't implement local time; ntp uses utc/gmt as the time base, and the local boxes adjust their time and timezones based on the client-local timezone definitions.
It could be that ntp is misconfigured, that something has gone seriously wacky with the ntp time base (hardware error? software error? network error? time-based attack? etc), or there's a rogue ntp server running.
Have a look at the ntp chatter in the system.log console log on the ntp server as a starting point, and at whatever passes for logging on the ntp clients, and at the settings for ntp. Out-of-the-box, there can be the requirement to tweak the ntp client or daemon configuration via the /etc/ntp.conf file, for instance. -
New to Solaris...need help with netra T1
I want to learn a form of Unix and thought Solaris would be a good place to start. I purchased a netra T1 in a package deal with some other equipment and am having a learning experience. The box came with Solaris 9, currently running 5.8. I can get the LOM interface up...I can get to the lom> prompt and the $ prompt but can't get any commands suggested by the install manual to work. The Netra T1 has a CDROM so I am trying the boot cdrom command...following is the sequence of events:
$boot cdrom
boot: not found
Any suggestions or links to documentation is appreciated.
BrittanOn the Netra you have three levels - lom (Lights out managment) is the 'bottom' level. From here you can control power to the box, etc
The next level is the OBP (Open Boot Prom) - This is the one you need to be at in order to do your boot cdrom
The top level is the OS running - if you've got a $ prompt, then chances are you're logged in as someone other than root on the server with the OS running.
To get to the OBP you'll want to be root. Assuming you know the root password type su -
supply the root password when prompted. Your $ will now change to a # this indicates you are now the superuser (root).
Now you can issue commands such as shutdown, halt, etc
shutdown -g0 -y -i0 (those are both zero) will tidy shutdown the box to the OBP
alternatively, if you're going to reinstall the OS anyway, you don't really care about a tidy shutdown and halt will do the trick
you're now at the OBP prompt ( ok> )
from here you can type boot cdrom
cdrom is an alias setup on the system and should be set to point to the CDROM device on your Netra -
How to sync clock of Cisco ASA 5505 from NTP Server on internet
Hi there!
i've setup a site, with cisco ASA 5505. It has public ip also.

How to set up loopback# as source fro NTP and/or built-in DNS server ?
I have created a loopback# interface which I would like to be used as the router source interface for the NTP client and/or built-in DNS server so everything originating whithin the router has only one and unique IP address (such as: logging source-interface Loopback#)
The documentation explains how to create virtual interfaces but I cannot find how to associate them to the mentioned services except logging.
IOS is 12.4.15T.9For DNS, maybe this would do the trick:

The thing is that XR ntp clock selection is a bit different then iOS and follows the specs very closely which results in this erroneous loss behavior.
For instance, you could also see this issue with a sync loss if the update time is only 500msec off what it was before and that will result in a ntp sync loss rather then adjusting to it.
Also I wanted to mention that the ntp prefer is a bit of a misnomer in XR (since it follows the specs differently then IOS) and this knob was taken over from IOS really.
You might get some joy if you set it to one server only and see if that helps?

Above script is to set the default permission of /tmp & /var/tmp while rebooting if it found any inconsistencies. I changed the file permission of /tmp and rebooted my server. As the above scripts are not running, it shouldn't change the file permission to default. But the file permission changed after reboot.
Please let me know is there any other service running related to this in my server. Was this script incorporated in SMF facility, if so whats that service name?
Thanks,

To run shell script from Oracle Forms, I used the following host('/bin/bash /u01/compile.sh') and it works well
Now, I need to run unix command something like
host('mv form1.fmx FORM1.FMX') but it's not working
I tried to append the command mv form1.fmx FORM1.FMX' to the compile.sh shell script but also it's not working although the rest lines of the shell script is running well -
Slow logins to domain, several event ID errors (group policy, netlogon, NTP errors)
We have a laptop user who was experiencing slow logons in a remote office. (Remote office has 100 users, only 1 is reporting the issue). Helpdesk swapped computers to give the user brand new hardware. The new laptop worked
fine while in the IT department in the main office, the user returned to their desk in their remote office after replacing the laptop and logged in and experienced the same slow logon issues as the older laptop.
Logons take up to 45 mins to process. (Login script hangs and does not process). During the process, you can check IPConfig and it received the proper DNS settings. you can ping the authenticating server by name. We have scanning
on our local copiers setup to scan to the users desktop, and this errors out. DNS on the AD controller shows the proper IP address for the machine and you can ping the machine by name.
System Event log is loaded with errors:
Event ID 5719 - Netlogon, computer not able to setup a secure session with a domain controller in the domain
Event ID 1129 - Group Policy, processing of Group Policy failed because of lack of network connectivity
Event ID 129 - Time Service, NTP Client was unable to set a domain peer to use as a time source
Event ID 5783 - NetLogon, The session setup to the WIndows NT or 2000 domain controller (xxx) for the domain is not responsive. RPC call cancelled. (NOTE - you can ping this domain controller by name and by IP with no issues)
Event ID 130 - Time-Service, NTP client unable to set a domain peer
All these seem to point to RPC errors timing out because they cannot communicate to the network resources. The problem happens on wired or wireless connections. We had the user move to a different network connection (one we know is working for
another user) the problem persists. The problem was on the original computer and continues to happen even after replacing the hardware with a brand new laptop.
I have tried running the following hotfix. Which does not resolve the issue:
http://support2.microsoft.com/kb/2459530 which technically this shouldn't be an issue because we use DHCP off the 2003 AD domain controller.
I have checked the domain controller, AD Replication is processing with no issues. DNS is working. The local DHCP server has no issues or events related to this account and neither does the local DNS server or the authenticating server (which
is in another remote office).
Hi,
As we know, most of the time error event 5719 is caused by network connectivity issues or name resolution issue, I suggest you refer to this link to make a further analysis

Oracle VM Server 2.2 Linux Guest cannot ntp to server properly
Hi All,
I have installed a VM guest Oracle Linux Enterprise 5U6 in Oracle VM server 2.2. I follow below procedure to config NTP in VM server.
https://blogs.oracle.com/virtualization/entry/configuring_ntp_services_for_oracle
However, when I apply the NTP configuration with VM server itself on the Guest, it detects the NTP server in high jitter value. Even though the stratrum is lower than the local host, It still cannot use that server as NTP source. Here is some information about the NTP debug and IP address.
IP Address:
Oracle VM Server: 172.16.8.100
VM Guest: 172.16.8.102

JackyHi Avi,
Thanks for your reply. Due to we do not have Oracle VM Manager, I did configure the VM guest to point the internal NTP server (172.16.90.1) which is mapped by Oracle VM server, but the high jitter is still existed while the guest can ntpq the NTP server. Thanks.

Solaris 8 on netra T1 error - drive not ready
Hi I am hoping someone can help shed light on a problem we have encountered. I inherited a couple of very old netra t1 with solaris 8 on them. We had a major power outage whcih resulted in an issue with this server coming backup. On first looking at it i was able to get into the server via lom command prompt, i ran the power down command to gracefully shutdown and reboot but on starting backup the server is reporting 'drive not ready' and just hangs at this point.
apologies but i am a solaris novice, any help would be much appreciated. I am hoping this is something trivial....
thanks.Just to update we suffered another power outage and returned to look at hte server to find different error messages appearing, this time the server was giving me the option to try and boot or go into single user mode, which i did and ran the metastat and got the following:-

Hi, all.
I get a couple of netra t1 105, and I'thinking about install Solaris 8 02/02.
Does the netra support that release?.
If so, need I patch them?.
Where can I get information about hardware platforms witch support Solaris 8. I didn�t find any about this in sunsolve.com
Any info is welcome.
Thanks all.The SunSolve System Handbook will show you minimum OS requirements for any Sun machine. The sun4u architecture (includes Netra t1 105) is in no danger of going End Of Life any time soon as it is supported in Solaris 9 and future Solaris 10. The support for sun4d architecture (SPARC Center 1000 & 2000) got dropped in Solaris 9. sun4m architecture (SPARC 5, 10 & 20) may get dropped in Solaris 10 but the sun4u architecture will be around for a while. There hasn't been a new architecture released since sun4u so there's nothing to worry about for quite a while.See:

Network Booting Solaris 10 on Netra T4 - scratch memory overflow error
Hi,
I recently got a hold of a Netra T4 server, and am now trying to install Solaris 10 on it. Since the server can DVD-driveless, I had to resort to booting it over the network from a boot server. I have progressed through a series of errors, from not configuring the NFS correctly, to making sure the RARP was on as well.
The current issue that I am having is when i start the boot (boot net -v install), it begins to load the image, and then haults when it reaches:
Rebooting with command: boot net -v install
Boot device: /pci@8,700000/network@5,1: File and args: -v install

I'm not exactly sure why this is occuring, or what I can do to resolve this. Has anyone else come across this scenario? Judging from google searches, I haven't found anything that can help me fix this. Hopefully someone can.
Thanks a ton,
Kyleas well, I have tried using various directories to install from, all coming to the same result.

Use of NTP pool in NTP configuration
I had the following queries with respect to the use of NTP pool in the NTP configuration on RHEL:
1) I see the following public servers from the pool.ntp.org project in the default /etc/ntp.conf file.
server 0.rhel.pool.ntp.org
server 1.rhel.pool.ntp.org
Would using these servers be fine or are there servers specific to India as we are located in India?
2) Time to be taken from the public servers above may not be ideal, I was wondering how much could the difference in time be say over a 1 month period?
I hope, my question is clear.
Please revert with the reply to my query.

Use the <n>.in.pool.org servers because they are much closer to you.
2) Time to be taken from the public servers above may not be ideal, I was wondering how much could the difference in time be say over a 1 month period?
How long is a piece of string? Your question is unanswerable. Syncing with external clock references is fine because you can use as many reference clocks as it takes you to feel comfortable; I'd suggest 4 or 5, and also turn on the local software reference clock.
