Server WRT1900AC DNS (?) Questions

It is a separate, but related to the thread - question WRT1900AC DHCP do not distribute the specified static DNS entries

I have not seen this documented function of anywhere, but it seems that the WRT1900AC has an internal DNS server? The router is set to dhcp clients local (front & reverse) on my local network with DNS suffix that is issued by my ISP (via external DHCP). Accordingly, it is causing conflicts on my network name resolution.

Example: My router receives its external address via DHCP from my ISP (WebPass). The optional parameter "domain name" is not editable (see screenshot)

Now, when a dhcp client internal registers on the network with a name in conflict (for example, the www host name) it will cause a DNS conflict on the LAN:

Nslookup www.web-pass.com

Server: 172.16.1.1

Address: 172.16.1.1 #53

Name:www.web-pass.com

Address: 172.16.1.110

where it should resolve correctly to 184.106.186.186. In addition

Don't get me wrong, I'd like a DNS local on my router - but for it to be functional and conflict prevention, the following must be done:

  1. Allow editing of the "Domain name" field to create a distinct and not conflicting namespace.
  2. Allow the ability to add static DNS for non-dhcp clients
  3. Leave the option to disable the local DNS server, for those who use & prefer their own internal DNS server
  4. Fix the bug (DHCP/DNS) mentioned at the beginning of the wire

If anyone has thoughts, observations, any other solution to workaround it please feel free add on this thread.

Linksys support reached out for me and I got a call with one of its engineers (Julie Louh - which was very useful) on this subject. It also has the problem of DHCP/Static DNS (mentioned at the beginning of the original post) of design to allow the IP address of the router to resolve the site of smart wifi Linksys (Cloud / anywhere configuration). She confirmed that the router uses IP addresses is entered in the static DNS config for DNS lookups.

On the DNS server issues described in this post, it should present the following feature requests:

  1. Allow editing of the "Domain name" field to create a distinct and not conflicting namespace.
  2. Allow the ability to add static DNS for non-dhcp clients

Of course, these feature enhancements will move up the chain of management for approval. But I think that if these 2 are implemented it will solve the main problems described here.

On a separate note, I was very pleased with the customer service and the reaction of Belkin/Linksys. The personal reachout to a technical support technician really shows that they are determined to make this powerful router and feature rich as they promised it would be.

    I've shot down the forums and the Web and cannot find a match. The nugget only that I can add, it's that I use JDeveloper with the extension of the OA framework. I've been successful creation of pages with the OA Framework and execution of their. Y at - it an incompatibility with OA and ADF framework?

    Any help is greatly appreciated!

    Mchrist,

    You may not use download OA Framework to develop applications of the ADF.

    I create two batch/command files: in each of them, the JDEV_USER_DIR value and other environment variables to point to a suitable location and run the JDeveloper.

    Just unzip JDev and OA Framework to separate places and make sure that the user for each directory is in a separate location as well.

  • Router (wrt300n) acting as a forwarder/server/resolver dns, why/how?

    Hello

    Modem speedtouch 516 defined as = bridge

    Router = linksys wrt300n, made the pppoe dsl connection

    OS = vista 64-bit, also have test with computer laptop linux clean/white

    By making a few landmarks on the dns servers, a tested program 192.168.1.1.

    This made me nervous and start questioning why is this and is there a problem of problem/vulnerability/security/etc.

    192.168.1.1 is my default gateway so my router.

    Do a "nslookup - 192.168.1.1' (temporary use this specific ip address as a server) and then by typing a url returns a response.

    According to tech-live chat, this router does not have dns forwarding nor made any linksys router.

    If the router doesn't do not dns forwarding how is, I get dns results when you do a nslookup or change the dns at 192.168.1.1?

    On some tests (dnsbench of grc.com) 192.168.1.1 is faster than dns servers that my ISP router forwards/gives. If the router was dns, it would normally use the dns ips he has in his list given to him by my ISP, right? So 192.168.1.1 and ISP - dns speed should be the same speed, no?

    Am I lack/misunderstanding something?

    Help. Thank you

    1. If the beneficiary address DNS server to the client is 192.168.1.1 router must do DNS redirection. Otherwise the customer could not resolve host names. There is no other way to do this if the client knows nothing but 192.168.1.1.

    2. the router uses the servers DNS ISP as shown on the router status page. Here are the only addresses that the router knows.

    3. the router is probably a DNS caching, also, so the router's responses are faster if the result is in the cache.

    4. as it is a redirector is also vulnerable or not vulnerable to the poisonings and other things your ISP DNS server.

    5. you can not handle. This is a redirector maybe with a bit of cache memory.

    6. If you set like him your other DNS server on your customers or in the DHCP server.

  • RT 8 Windows Server 2008 newbie question

    Hi guys,.

    Just saw a difference between server 08 & 08 RT server is that RT is only 64-bit. Is this to say that the server is accessible only by the 64-bit systems?

    Also, I'll be able to connect to the server with older versions of windows / other operating systems?

    Thank you!

  • Recurring Server primary DNS does not.

    My PC (Windows 7 x 86) problems of connection to the internet. It connects for a few hours, but sometimes it disconnects for a few hours due to a problem with the communication with the server DNS - principal.

    netsh int ipv6 reset reset.txt

    ipconfig/flushdns

    ipconfig/release

    I connect to internet after these, but a few seconds the ping (ping 125.5.6.1) becomes the request timed out.

    I tried already several such as Google and OpenDNS DNS servers and yet, nothing helps, same case my ipv4 and ipv6 DNS can also be programmed to automatically get.

    TL; DR

    Do you have all the commands and even changed DNS. Works for a few seconds but disconnects after a few seconds anyway.

  • UCS C200 Server Power Supply Question

    We make some changes in our data center and which involves electric grid.  We had to replace our Dustribution of power rack and to respond to the charge, we moved 208V, 3 phase power distribution.  Read the literature, I see that the power supply to the UCS C200 servers can operate 115V to 230V AC.

    My questions are: is it everything I have on power supply from 120V AC 208 v power supply power supply power supply?  Can I have a power running at 120 v and the other operating at 208V?  I try to avoid the closure of the server.

  • IP name-server and dns server

    Hello world

    Could someone tell me the difference between the two commands please?

    IP-name server

    (in DHCP pool installation)

    DNS server

    I don't understand if I need two of them, or what you do.

    Thank you

    Triet

    Triet,

    The name-server ip x.x.x.x is for the "router" to reslove DNS queries.

    In the DHCP pool, the x.x.x.x dns server is for the DHCP client to use for DNS queries.

  • Upgrade of the VCSA Server 6.0 question

    So I've published partially in another thread, but now think it's worthy of its own question and explanation.

    I have 2 sites with a 5.5 VCSA deployed to everyone and now you can add vRA to the environment before adding I want to back to 6.0.  What I see is a general idea that when there is doubt separate the PSC to vcenter.  So, how do VCSA 5.5 6.0 VCSA with external PSC?  I saw a mention of the change in the environment before moving on to 6, but I think it's all installations of windows based; as I can't find any external sso type unit for version 5.5 (identity server has failed).  I decided to try and deploy to 5.5 and 6.0 PSC vcsa then cross the vm KB 2094888 but no luck there.  I try not to use inventory backup / restoration of the tool, but it's the only option that I can find.

    So, to sum up how to 5.5 VCSA VCSA with external PSC 6.0?

    Offers built-in level only vCenter Server Appliance U3 5.1 or newer and 5.5 with SSO are supported. vCenter Server Appliance 5.1 U2 or more don't are not supported. vCenter Server Appliance U3 5.1 or newer and with external SSO 5.5 are not supported. A supported upgrade path is planned for a future release.

    Please, go through vSphere 6.0 Documentation Center to learn more about VCSA upgrade and started upgrading to vCenter Server 6.0 recommended (2109772) section of the knowledge base.

  • DNS question... Help, please. Cannot join the client to the domain.

    I played with workstation 10 for about a day now.

    I'm pretty green when it comes to the DNS configuration. The reason for it, for the experience.

    I created a Virtual Server R2 of 2012 and a VM 7 Win machine. I'm trying to join the VM 7 Win the field laboratory.
    I've already promoted the server to be a domain controller.

    The error I get is:

    An attempt to resolve the DNS of a domain controller in the domain being joined has failed. Please check that this client is set to reach a DNS server that can resolve DNS names in the target domain.

    Not sure what is the cause.

    In the IPV4 properties, I changed the DNS server to use the IP address of the domain controller that I read but still no luck.

    Also how can I set up the network for the VM?

    Thank you

    Jason

    Come on come on client machine Winodows 7 > network and sharing Center > adapter set it > right click Local area connection and click Properties

    Double-click PTC/IPv4

    In the preferred DNS server, type the IP Address of the domain controller and see if that helps the problem.

    Also check if the firewall is blocking communication. Disable the firewall and check.

  • Easy VMware vCenter Server for Essentials Question

    Hi all

    We are looking to buy VMware vSphere Essentials for use in our Test/development environment and had a question about vCenter Server for Essentials. I know this is a light version of the 'standard' vCenter, but is there any reason that I could not run this version in a VM to manage the node 3 environment "Essentials" like I do in my "regular vSphere cluster?"

    TIA,

    -Jason

    I see no problem at all with your server vCenter Server running as a virtual machine. In addition, it is fully supported.

  • Migration to SQL SERVER 2008 for questions of Oracle 10 g.

    Hello

    I'm trying to migrate from SQL Server 2008 to Oracle 10 g and I end up with a few problems that I wanted to ask you some info about it.
    First of all, I followed a tutorial
    http://St-curriculum.Oracle.com/OBE/DB/hol08/sqldev_migration/MSSQLServer/migrate_microsoft_sqlserver_otn.htm
    and and in the latest version of Oracle SQL developer, I downloaded, I found not the Output of the Script of Capture of database load option.
    My first question is how can I add either this option or y at - it a new way to load the script to capture?
    Can I use the migration wizard and after all, I had the full message of migrating the application.
    When I tried to open my connectionss, he told me version 11.2 is necessary. Does this mean that developer Oracle SQL 3 only
    perform the migration of oracle 11g? And if I tried the previous versions, it does not support SQL server 2008.
    What should I do in this case?

    Thank you!

    The output of the Script Capture charge of database can be found in the tools of-> Migration section.

    You have already discovered the "create data base Capture Scripts" in tools-> Migration menu and you have run the script that generated the DAT files.
    Now click on tools-> option-> Migration migrate, choose your repository, add a project, and then on the next page you must choose between ONLINE and offline mode. When you use the DAT files, please choose the offline mode and add the * ocp file with the subdirectories that contains the DAT files.

    SQL Developer is able to connect to Oracle 10.2 db as well. Can you please be more specific about the second question and provide more details the steps that you did?

  • NAC Guest server - time for questions

    Hi all

    I'm having trouble with our NGS. He used the 2.0.0 version but only tha start-end type according to time worked with this version. We decided to upgrade to version 2.0.1.

    We now have other types of the function of time and that they are working correctly but start and end time profiles stopped at woking. New users cannot be created using these profiles of time because the month field is empty and impossible to select the month. If the date is selected using the calendar, the month field is left blank. Creating user can be started, there is no error message but the END does not create the user and the page expires.

    I tried to restart the server, but the problem remains.

    Has anyone seen this problem? Any solution or workaround?

    Hello

    You might be hitting CSCsz80188. Please see the bulletin which. He planned to be fixed in 2.0.2, but workaround listed too.

  • ISE with DNS question

    Hello Techies,

    I'm challenge when configuring ISE to join AD. Domain name lookup fails. DNS works perfectly well;

    nslookup works fine on ISE for simple domain names, but domain names long he fails all by throwing the following error;

    ;; Truncated, retrying in TCP mode.

    ;; connection has expired; no servers could be reached

    While searching on google, threads can discuss it delivers a common with linux, when several IP is returned by the DNS query. Solution is to make static entries

    /etc/resolv.conf

    Not able to find it at ISE, such that it does not provide access to the operating system. I'm running on VMware.

    Looking forward for your valuable contributions to solve this problem.

    Thank you

    Hello

    You need to work it with TAC for that matter, I'm not aware of any bugs on reach AD due to a long suffix, but it would be something to work with them on. Also are there any ACL or firewall blocking DNS environment ISE tcp ports?

    Also, check to see if you can resolve the hostname of the ise and its ip address (front and rear).

    Thank you
