NTP CONFIG

All,

I have a config NTP work but all my time on all my routers is off due to DST. I am on the side is. Is it possible to configure the ntp config to include daylight saving time?

Mario

I think that the answer you are looking for in the NTP config is not a command of the clock. Try this:

clock to summer time EDT recurring

I guess that your config probably includes:

clock timezone IS - 5

that establishes that you are in the Eastern time zone. Otherwise, the time must appear as UTC.

  • ASA5505 NTP Config

    Hello

    We have hosts autonomous (not on a main domain controller) behind an ASA 5505 and we want to set their clocks to synchronize with an external NTP source. I wasn't sure if I could configure the ASA to use external sources of NTP and then point the hosts to synchronize clocks with clock of the SAA. What is a good implementation?

    Thanks in advance.

    Best, ~ zK

    The ASA can act as an NTP client, not as a server.

    He just point the hosts to an external NTP server and let them to synchronize. If you have an access list on your inside interface (restrict the outbound traffic from your LAN), then just add a statement of license to ntp (123/udp).

  • Single ESXi NTP config

    There is a lot of discussion about it in other communities, but I need to make sure I'm set up correctly for my environment.

    I have no internal NTP servers, so I put the date and the correct time (my time zone) in the BIOS of my server. What about Setup NTP on ESXi I thought use pool.ntp.org. I've never used this before, but a lot of people here seem to use it.

    My time zone is UTC/GMT + 2 hours (Sweden) and in looking at pool.ntp.org servers:

    0.se.pool.ntp.org

    1.se.pool.ntp.org

    2.se.pool.ntp.org

    3.se.pool.ntp.org

    My simple question is should I enter all four in the NTP configuration, and I should also synchronize time from the BIOS of the server?

    With regard to my VMs, I guess that I would like to use VMware Tools synchronize to the ESXi host and automatic time updates disable Windows, correct?

    Thank you

    Not much you can do. ILO takes that is the hallmark of the system clock or an ILO agent running on the host operating system. In this case, ESXi uses offsets from GMT and resets the clock of the host at the time GMT. Might be worth pointing out to HP for CIM providers could communicate from zone information to the ILO?

  • Automatic installation using KS.cfg

    I created the KS.cfg file using the GUI installation. I want to be able to install this for about 20 ESX host. I am familiar where to modify the partition information and server name and IP address for each server. My question is to know how to add this to the installation on USB it will not because it's a server blade at the remote location. Installation will be done remotely through the ILO. I saw where someone suggested inserting this ISO file with magic ISO. How would this work for 20 servers since I assume that your will need a KS.cfg file for each server. Also, what people add to the post installation script? NTP Config, Virtual Switch configuration, configuration of firewall?

    Thank you

    Mike

    msemon1 wrote:

    So if I have 20 ESX host I have to inject 20 KS.cfg files into ISO and choose which on startup?

    Indeed, all 20 must be injected into the ESX installation media.  Mounting the isolinux.cfg lets just arrow down to them.  Very easy installation.

  • ESXi host does not synchronize with NTP - causes HA config failures?

    Hello

    We are currently implementing some Cisco UCS systems. We using blades Cisco UCS B200 M1 (x 5670, 48 GB of RAM)

    Everything seems to work fine except these little things, which seems to be related.

    1 NTP synchronization is not happenning, or happening very slowly.

    2. a 10 cluster host, when it is configured for HA, has many guests who fail to be configured for HA (for example we had only 2 guests get properly configured for HA out of 10).

    Initially, I thought REP 1 and 2 were not related, but then I remember reading somewhere that the ESXi host must have simultaneously for HA to work.

    On question No. 1:

    10 guests have a difference of 5-6 minutes between them. Curiously, the first hosts that are connected to a HA cluster, if their duration is similar, they wil work.

    But others are more than 1 to 2 minutes off, they will fail. Our NTP is configured on 2 internal NTP servers, which syncs with the outside world - the 2

    NTP servers are:

    The default gateway of each ESXi

    The network Core switch

    We know that the NTP servers work correctly because our advertising is synchronized with them and we checked on our domain controller local time main external time source.

    Debug information

    Everything has been configured through the GUI, I show the output of ntp.conf for confirmation.

    We tried to restart the hosts (without success).

    Everyone knows what we can do to solve this?

    Thank you

    You tried to restart NTP.

  • NTP and config of time

    I read somewhere that it is best to set your BIOS to UTC clock on your physical hosts and use NTP to synchronize... is this true?

    In addition, when you use the public ntp servers, I can't tell if I have to use

    pool. NTP.org

    or

    0.pool. NTP.org

    1.pool. NTP.org

    2.pool. NTP.org

    ESXi uses UTC and if I remember will define the clock machine to stop. Each of the pool.ntp.org references are very good but it it is useful to use something more high in the chain. In North America using the 0.north - america.pool.ntp.org can get you less crowded but servers geographically close times more.

    0.North - america.pool.ntp.org

    1.North - america.pool.ntp.org

  • Cutting of NTP on specific interfaces

    Hello

    I want to be able to use our HQ Internet like NTP source router for the rest of our network equipment - including other Internet routers at remote sites. It is all set up and everything works fine, but I would like to disable NTP on external face interfaces for remote sites...

    In my view, that which will achieve...

    config t

    int g0/0/0 (interface in the face of Internet)

    Disable NTP

    !

    In this way, I'll still be able to get my info the Inter HQ routers IP MGMT NTP.

    But,

    for the HQ Internet router, I need to be able to access the Internet NTP servers we get our clock info from. On this router 'disable ntp' on the interface-oriented Internet break NTP. What do I need set up on the router internet HQ-oriented interface Internet to stop the router from a source to anyone on the Internet, but still be able to get info of the clock of the Internet and act as a source for the rest of our network equipment?

    I thought it would work "no source ntp interfaceinterface", but the command is not supported on the 4400 s I guess that.

    Thank you, Pat

    Your configuration looks good. Access group "peer", it's the only one that actually allows a router to BE synchronized, so to speak, that is, influenced by other devices. The "serve only" allows (HQ router in your case) to update others, but not BE updated or influenced by others. Who is?

    So that the router HQ to reject applications for IPs defined Internet, but always to accept updates from these IPs, the group 'serve only"access must be configured on the routers of the Internet. Think about it, it is almost certain that these routers have configured this anyway, because they won't have their time synchronized with you, or any other customer endorsement.

  • Review of the ASA 5510 Config

    Hi all, I'm about to replace an existing a new ASA 5510 firewall.  The environment is pretty simple, just an external and internal interface.  I put in correspondence configs as much as possible, but I'd like to see if there are obvious problems.  I am concerned mainly with my NAT statements.  Nothing in the following config (sterilized) seems out of place?  Thank you!!

  • Configuring NTP on IDS4215

    Hello

    I'm new in the environment of the IDS, we are planing to configure the NTP server on the case IDS 4215.

    I have a completed order for the same ones mentioned below.

    probe # configure terminal

    host service Sensor (config) #.

    NTP-option enable Sensor(config-HOS) #.

    Sensor(config-HOS-ENA) # ip_address key id ID ntp servers

    now the problem for me is that I don't have the key id & key-value for my ntp server.

    Can someone help me NTP configuration with the key - id information.

    Unfortunately 8,0000 E3 is quite old and does not support unauthenticated ntp.

    The train of 5.1 was end of Saled and is approaching quickly end of life / end of Support of Signature:

    http://www.Cisco.com/en/us/prod/collateral/vpndevc/ps5729/ps5713/ps2113/end_of_life_notice_c51-468830.html

    Last date for Signatures for version 5.1 is on 24 October of this year.

    If you only 4 months rest before you would have to spend to 6.0 to continue to get the updates of the signature.

    The 4215 is also end of Saled, but it is end of Signature support is not until July 29, 2011.

    http://www.Cisco.com/en/us/prod/collateral/vpndevc/ps5729/ps5713/PS4077/ps5367/end_of_life_notice_for_cisco_ids_4215_sensor.html

    Version 6.0 is the latest version supports ID-4215, Signature updates to 6.0 for the IDS-4215 will continue at least until July 29, 2011.

    So if you upgrade to 6.0 now, you always 2 years more signature updates before that you have to purchase a new sensor.

    Version 6.0 (5) E3 supports the option of ntp unauthenticated.

    So, you will want to plan for an upgrade to 6.0 some time in the next four months.

    In the meantime, you'll need to use authenticated ntp keys.

    If you have access to a router you can try to use the router as a server temporary inbetween.

    The router would be configured to get its time for your ntp server. Talk to your administrator network on how to implement.

    Then configure the router to also be a server with a key of authenitcated.

    Here is a section of the CLI Guide explaining how to set up the router as key authenticated ntp server:

    http://www.Cisco.com/en/us/docs/security/IPS/7.0/Configuration/Guide/CLI/cli_setup.html#wp1035649

    The sensor would be configured to use the router as ntp server by using this key.

    This would be a temporary workaround until you can get upgraded to 6.0.

According to the command reference the 'indicates if Cisco Fabric Services (CFS) is enabled or disabled for the purposes of NTP and know if a fabric lock is in place, because a configuration is in progress'. NTP distribution is discussed in the Distribution of NTP CFS of the configuration guide.

    Concerning

  • EZVPN leak netflow and ntp to ISP

    I have a G 881 with a cellular modem from verizon with EZVPN in network Extension mode. This config is running Netflow packets directly on the cell interface. I want them to go to my IPSEC tunnel to my internal Netflow collector. Same thing is happening to NTP. Because these packages have (10.x.x.x) private IP addresses to the source field that Verizon maintains close the cell interface. I tried natting and ACL, but because these packages are generated by the router, it allows to circumvent these mechanisms.

    Does anyone have a work around for this problem.

    Have you tried your traffic NTP and Netflow how to associate a specific interface on your router? These interfaces include your field of encryption.

    Examples:

    IP flow-export Loopback0 source

    source NTP Loopback0

  • Access to the administration via VPN to 887 after config setup pro

    Hi all

    Ive just made a three 887w for a client in a few branches, and as this is the first time I have deployed these devices, I decided to go with the GUI (downloaded config pro 2.3) to get the configuration made that I had some constraints of time to get them in place (sometimes I go with the graphical interface first and then look back at the CLI to see what as its been) (, then hand it in Notepad to get a better understanding of the new features of the CLI may be gone and allowed).

    One thing I again, that I was going to do face was my first experience of the firewall IOS area type of config...

    At this point, I'm still unclear on the config (where why Im posting here I guess!) - but the main problem I have at the moment is with managing access to devices.

    Particularly with regard to access to the administration of headquarters inside the IP address of the branch routers.

    I should mention that the branch routers are connected to Headquarters by connections IPSec site-to-site VPN and these connections are all very good, all connectivity (PC server, PC, printer, etc.) is very well... I can also send packets (using the inside of the interface as a source) ping from branch routers to servers on the headquarters LAN.

    Set up access to administration using config pro to allow access to the router on the subnet headquarters (on its inside interface), as well as the local subnet and also SSH access to a specific host from the internet - the local subnet and the only host on the internet can access the router very well.

    I'm not sure if the problem is with the ZBF config or if its something really obvious Im missing! -Ive done routers branch several times previously, so with this being the first config ZBF I did, so I came to the conclusion that there must be something in the absence of my understanding.

    Any help greatly appreciated... sanitized config below!

    Thanks in advance

    access-list 103 allow ip 192.168.16.0 0.0.0.255 host 10.0.0.1

    This should take enable access to this IP address for hosts using ssh and https. Try this out and let me know how it goes.

    Thank you and best regards,

  • ESXi 5.1 configured as a NTP server, do not sync with the Local PC

    I have a 5.1 ESXi server configured as an NTP server and a Windows Server 2008 R2 local PC that are not sync.  I understand well, it is not recommended for ESXi, but I read [1] [2] that, whenever an ESXi server is running as a client, it also acts as a server, so I enabled as a NTP client in vSphere by ticking the NTP client, adding some servers to the server list, and then click on run, and I also activated the 123 incoming/outgoing port by adding the shell of ESXi firewall settings.

    I'm pretty sure it isn't a firewall problem.  I completely disabled the firewall on my local PC.  Running "w32tm keyboardists computers: - IP address of the server -" give me the time of the server and running the software NTPQuery gives me an answer back on port 123 of the server time.

    I tried:

    - Date/time settings (right-click on notification area-> set date/time-> Internet time-> set as the IP address of the server) - sync fails (* an error has occurred while Windows timed with - server IP-*)

    - Group Policy Editor (Computer Configuration\Administrative Templates administration\systeme\service Time Service, currently disabled but because I heard this causes problems) - synchronization fails

    - The registry editor (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\W32Time\settings) - synchronization fails

    - Command prompt, using:

    w32tm /config /manualpeerlist:-IP of server- /syncfromflags:MANUAL /reliable:yes /update
net stop w32time && net start w32time
w32tm /resync /rediscover

    This updates the registry properly, but the outputs "the computer did not resync because no time data was available."  And when I use the command "w32tm/query/source" the source is always "The local CMOS clock."

    Here is the output from w32tm/query /configuration

    Any ideas?  Thanks in advance.

    Your ESXi server response shows that the leap indicator is 3 and the server stratum is 0.

    This means that ESXi NTP server is synchronized and unable to provide a valid reference time to customers.

    We recommend that you configure your ESXi host with valid upstream NTP servers such as:

    0.vmware.pool.ntp.org,1.vmware.pool.ntp.org and 2. VMware.pool.ntp.org

    as described in the KB article or alternatively your internet service provider NTP servers.

    Although not recommended, you can configure ESXi to allow a reference time by using the own system clock

    If you can not configure ESXi to synchronize to external NTP servers upstream.

    UI, tab Configuration, using software (time setting), properties, Options, and NTP settings.

    Specify "127.127.1.0" as your single NTP server. Don't forget to check the box "restart NTP service to apply the changes.

    then click OK twice to close the dialog boxes. Wait a few minutes for NTP sync, then try your test.

    According to RFC 4330, NTP-SNTP (Simple) customers must not use time in a package of NTP response if the

    stratum returned is 0 (and the leap indicator is 3). Apparently, your client Windows NTP Simple is more

    the RFC.

  • Daily ESXi NTP healthcheck service

    Hello

    We have the need to monitor the config and status of our ESXi hosts the NTP service and tried some of the solutions mentioned on this blog. The last one I tried was posted by "jaydo123" but seems to be for a single post.

    Our goal is to interview guests and view state on a web page that could be controlled by our events team

    Example of the info we need.

    Hostname, NTPservice State, NTP server and the current time on the esxi host.

    We will have the page to refresh every hour.

    Has anyone ever had the need to do and if so any suggestions on getting this right.

    Thank you

    Johan

    Take a look on Script: check the status of ntp and time on your ESX Servers.

    It requires the use of plink to retrieve the current date of the ESXi servers.
