Changing the DNS server for ESX hosts?

Our network administrator will change the IP address of the DNS server.  In this way, we will change those corresponding to ESX hosts.

We would like to know

(1) can we change the DNS server on execution of the ESX hosts without going into maintenance mode?

(2) under what circumstances the ESX host will do use DNS servers?

(3) memory, we should add all the IP addresses of ESX host in the hosts file in the Service Console, where is this hosts file located at?

Thank you

Tony,

Use "service network restart" command to restart the network service

Do not forget also that...

Very dependent on DNS HA, HA will not work without the correct DNS configuration. The servers ESX and vCenter server must be able to resolve the name (FQDN full) / IPs in both feel to get a working HA.

  • Change the DNS server, but consider e-mail to Office 365

    I now have a customer who wants his site softdanmark.dk moved and accommodated with catalyst for business as the new design I've done for the company by muse and previewed as: softdanmark.businesscatalyst.com.

    I've already added the domain name to Business Catalyst and gave him the dns data, but he still wants the email (MX) belong to the TDC, where he has his Office 365.

    Is it possible to only move the DNS server and keep the MX record at the old company?

    10.10.5 Yosemite

    My ISP has provided DNS servers are terrible and I still get messages "site is not reachable. I'd like to change the DNS from Google or Open DNS servers

    In SYSTEM preferences > network > DNS tab I delete 2 default entries & entry "8.8.8.8" & "8.8.4.4" (google dns)
    In the "areas of research" box, there are 2 entrances & I can't delete them.

    I click OK & apply - when I go back to the DNS tab, it was the old DNS.

    What should do?

    May be a corrupt .plist.

    Make a backup, preferably 2 backups on 2 separate drives.

    Quit the application.

    Go to Finder and select your user folder. With this Finder window as the windshield, select Finder/display/display options for presenting or order - J.  When the display options opens, check "show the library folder. This should make your visible user library folder in your user folder.  Select the library. Then go to Preferences/com.apple.systempreferences.plist.  Move the .plist on your desktop.

    Restart your computer, open the application and test. If it works fine, delete the plist for the office.

    If the application is the same, return the .plist where you got it, crushing the latest.

  • Change the DNS server automatically when switching to WiFi network?

    I am usually connected to one of the two wifi networks, one I have control on and I'm not. When I am connected to that I have no control over, I usually spend my DNS settings of the network server (which often breaks down) to a third party one, but I end up having to do this every time. Is there a way so that it would automatically change my DNS server whenever I connect to this network? I am running Windows Developer Preview

  • Change the path information for ESX ESXi hosts to access

    Hello all! I hope you guys can help me.

    I have about 47 hosts that I need to change it Round Robin storage path information. If I make the change in vCenter and restart the host it again changing fixed. So, I thought that I should change it to the level of the host through esxicli.

    I have about twice as many LUNS of the Hitachi SAN. I'd like to see if it is possible to make the change in all areas, in some way, or I need to make the change by host? Also, is there anything that I need to change sides San so that it works or not.

    I saw this VMware KB: modification of path information for ESX/ESXi hosts to access and assume that it is the best plan? But did not know of all put into custody, if necessary, that everyone ran to when doing this?

    You will need to make the change by the host and the KB you'll find is the right method.

  • Change the DNS settings in the Pool of IP network

    Hello

    Due to a migration of our DNS servers, I have to change the IP addresses of the DNS servers defined in the (currently used) our BDE server IP pools. There is a Hadoop cluster with a large amount of data running using this pool and I do not have to deploy the cluster again. Restart of the cluster is not matter, so I planned the settings DNS for the cluster nodes have to change after reboot. Unlikely, I could not change the DNS settings. Is there a way (perhaps non-elegant) change those settings for the pool?

    See you soon,.

    Dustin

    Hi Dustin,

    BDE provides the interface to change the DNS server in the network added to the BDE.  You must change the BDE database to do.  Here is the solution:

    1 Server BDE connect you as user serengeti

    2. run this command: echo ' network dns1 set update = 'the_new_dns_server_ip' where name = 'the_network_name '; \q" | psql

    3. apply the new DNS server. There are two approach. You can choose one.

    (a) connection BDE CLI and run "cluster stop - name...". ' and 'start cluster - name... '. "to restart the virtual machines in the cluster, then the new DNS server will be applied.

    (b) on BDE server, run "serengeti - ssh.sh cluster_name " sudo sed-i of | nameserver. * | nameserver the_new_dns_server_ip| ' g' / etc/etc/resolv.CONF. The new DNS server should take effect immediately.

    Thank you for using BDE.

  • DNS server for the WRT54GS v6 problem

    This router running for 2 years without any problem (even on Windows7 since las year), recently it wont let me conect to the internet, network and say sharing that the configuration of the computer center are good but no response from the DNS server is present.

    (Windows 7 RTM Ultimate x 86, Bellsouth / AT & T ISP in Florida.) Conexion ADSL, nine cables ethernet and material held in the best conditions, the network card: Realtek RTL8102E/RTL8103 Family PCI - E Fast Ethernet NIC (NDIS 6.20) (v7.2)

    ================================================================================

    What I tried:

    Reset the router or modem (connected to a Westell 6100), in order to define the default settings and (based on the Web reset and reset buttons)

    Flushing IP in CMD

    Make the web based configuration for my WRT54GS v6, releasing DCHP, renewing, defaults, etc...

    Upgrade the firmware to v1.52.7 (latest) nothing helps, dating back to 1.52.6 original.

    Shows Device Manager hardware works correctly.

    Windows 7 show me a link to view the properties of my WRT54GS when I right click on it, I also see the "Enable" option, but every time I use it I get "Connection Failed!"

    ===========================================================================================

    I'm not much of a tech guy, and read the forum does not help me a lot, so I ask for help please.

    PS: CD installed by default for her with her old EasyLink Advisor without success, tried also the last 2 Lela EasyLink Advisor, nothing helps.

    In addition, there is no default gateway glancing an IPCONFIG in CMD and now there is (192.168.1.1), which I use to enter its web-based configuration.

    That your ISP is a DSL provider, most of the DSL Modem has a DHCP server on them, so they act as a router. From now you the type of connection is NAT behind NAT.

    Order for your Linksys router to work with a DSL Modem. Connect to the Linksys router and on the Configuration tab configuration page, you must modify the "local IP address" to 192.168.2.1 and click on save settings...

    Once the settings are saved, unplug the power to the router and Modem, wait 30 seconds and then plug in the power to the Modem, and once all the lights are cover then you can connect the power supply to the router and check if you are online.

  • What are the technical requirements for web hosting server?

    Does anyone know what are the technical requirements for web hosting server? I couldn't find anything!

    THX!

    It is not really all of the requirements. All web servers that support the HTML will work. You would have a very hard time finding a host that will not work. It's just straight HTML, CSS and JavaScript. However, if you plan to use forms or in the browser edition you will need a server that supports PHP. But again, it is pretty well 99.9% of Web hosts.

  • Static IP address of WiFi requires the DNS server

    I was able to confirm this on two separate MacBook Pro (various models) the two Yosemite running 10.11.4.

    After assigning a static IP address to the wireless network interface, the MacBook ping to a address beyond the gateway by default unless there is also a DNS server on the wireless interface. I wouldn't need a public IP address ping DNS server.

    For example:

    This method works.

    But it does not work:

    At least I have change the DNS like this:

    Then it starts working again.

    I tried to initiate a capture of packets and the MacBook is not even send ping on the wireless interface requests unless there is a static DNS server assigned.

    Can anyone other confirm/deny this behavior for me?

    Thank you

    Rob

    What exactly are you trying to do?

    You try to assign a Mac with a LAN IP address? If so, do it in the router by selecting an IP address on the local network to use with the Mac Machine (MAC address). This assumes that your router is your DHCP server. Otherwise, you need a DNS server that is running on your local network to be able to distribute IP of DHCP addresses.

  • How to manually change the DNS zone files?

    I'm running OS X version 10.11.2 (El Capitan) and using App Server version 5.0.15 on a Mac Mini.

    I need to change the DNS Zone files manually because the DNS Server App Manager does not provide a U / I in order to add some elements (such as adding a delegation, etc.).  I use TextWrangler (5.0.2) as editor-in-Chief.

    I found an old post on how to do this here, but the information listed it seems obsolete.

    I was able to find the zone files to:

    / Library/server/name

    as:

    CBI .

    When I try to save or overwrite the db. files, or try to save all the files in that directory, I get an error indicating that:

    "Save the authenticated for this file failed (error application code: 20004).

    Since a window Terminal, if I go to that directory and type:

    Echo hello > temp.txt

    I get:

    Permission denied

    I am logged in using an administrator account.

    Before editing the db. files, I turned off the DNS in the App Server, then exit the server application server.

    What should I do to manually update the db. files?

    These files are protected from root.  You need to elevate your permissions to be able to change them.

    Probably you use a text editor like vi, nano or pico command line.  sudo vi/path/to/file for example.

    Back up the files first to protect against error.  In addition, be aware that Apple can run on some of your changes if you change the.app areas.
