Assistance with DNS/FQDN

I am having trouble setting up my DNS for hosting my domain/website on the internet. As I am faily new to DNS settings, any assistance would be greatly appreciated. My settings are listed below;
NAME TYPE VALUE
0.168.192.in.addr.arpa. Reverse Zone -
192.168.0.195 Reverse Mapping svr.khnum.ca
195.0.168.192.in-addr.arpa. Reverse Zone -
192.168.0.195 Reverse Mapping svr.khnum.ca
khnum.ca Primary Zone -
svr.khnum.ca Machine 192.168.0.195
web (http.tcp) Service khnum.ca:80
** I am currently behind a D-Link router/firewall using DHCP to assign network addresses. I have reserved the IP address for the server on the router.
My IP address from my ISP is 2*.110.115.9, subnet mask is 255.255.255.192, default gateway is 208.110.115.1, primary DNS is 209.53.200.3, and secondary DNS is 66.51.128.241.
** I am used to using Windows, the OS X environment is a tad new.
** When I run a tracert on my FQDN khnum.ca I get 206.12.82.193, which seems to be the company I registered with.
Thanks.

What are you trying to do?
The simplest is to draw a line (at your firewall) between the public DNS domain and the public network, your private DNS and private IP addresses, and use NAT to bridge that line. Basically leave your external DNS names alone, and use NAT to go from your public IP address to your internal IP address. Set up a parallel DNS inside using a subdomain of your registered domain, a different registered domain, or a made-up domain.
Then (for details) [read this|http://labs.hoffmanlabs.com/node/1436] for more details.
And get out of 192.168.0.0/16, and over into 172.16.0.0/12 or 10.0.0.0/8 while you're setting stuff up. Get into a different subnet, and well clear of 192.168.0.0/16 that everybody uses. That change makes (future) VPN routing easier going forward.

  • Assistance with DNS - RFC 1918 response from internet

    Hello - I recently noticed some errors in my DNS log. I looked into the errors and it seems that I do not have any empty zones setup. Everything is right in SA, however it does not seem to be correct in the actual config. files. The following is a sample of my log. Does anyone have an idea what's going on/what i need to do to resolve this issue. Any help is greatly appreciated.

    No, you're still not (quite) getting it.
    The addresses in the log are from computers in our network
    You mean the client address, right? not the address of the host that was being looked up.
    . If I am reading the log right, our clients are querying a root server when they should be querying the local DNS
    No, that's not what it's saying.
    Given the log line:
    15-Mar-2010 09:19:49.130 client 192.168.89.254#3054: view com.apple.ServerAdmin.DNS.public: RFC 1918 response from Internet for 10.141.168.192.in-addr.arpa
    This means that the client (on your network) at 192.168.89.254 asked your server for the reverse DNS lookup for 192.168.141.10.
    Since your server doesn't know anything about 192.168.141.10 it queried the root server and got back an RFC1918 response (because no public server should ever respond to a query for a 192.168.x.x address).
    The point is that your server queried the root server, not the client on the network. This is exactly the same as if the client requested a name lookup for a domain that the server didn't know about - it would query the root servers to find out where to get the answer. At no point, though, does the client query the root server and, indeed, since you're seeing this log entry it means the client is correctly configured.
    I have no idea where to troubleshoot,
    What's to troubleshoot? As long as you don't expect to be authoritative for 192.168.141.x there's no issue here (other than maybe why the client requested that address in the first place). In short, this kind of thing happens all the time and I wouldn't think twice about it as long as 192.168.141.x is not one of your networks. If it is then clearly your machine isn't setup to handle that zone which might be something to address. You haven't yet stated whether you expect to resolve 192.168.141.x addresses or not.

  • Global Loadbalancing with DNS

    Hi
    In the CSS Global load balancing I was going through the description of using the setup desribed, but I am confused about the following statements
    "An application session is configured between two CSS switches in two different geographic locations. There is no requirement for a point-to-point link joining the sites; the only requirement is that the two sites can route to each other.
    Using the CSS switches DNS capability, a higher level DNS server (in this example, the one authoritative for yourdomain.com) will be configured to use both CSS' circuit VLAN address as NS records for a sub-domain called www.yourdomain.com. Whichever CSS is referred to by the higher level DNS server will then resolve that a record request with the IP address of the DNS content rule on the CSS.
    The primary site will be preferred through a combination of using an ACL on the secondary CSS, an application session between the two CSS switches, and configuring the above mentioned NS records on the higher-level DNS server"
    Here are we only using the DNS feature of the CSS or another external DNS as well.
    The information was obtained from the URL
    http://www.cisco.com/en/US/products/hw/contnetw/ps789/products_configuration_example09186a00801dcd75.shtml
    Any assistance would be extremely helpfull
    Thank you
    Regards
    Aiyappa

    there is always an external DNS due to the protocol nature.
    If you have a DNS server for your domain, say cisco.com, you will create an entry on this dns server to point www.cisco.com to the 2 CSS.
    When a client does a domain name resolution for www.cisco.com they will first query the .com server, that will redirect the dns request to your server .cisco.com that will redirect the request to www.cisco.com which will be a CSS that can answer the DNS request with the VIP address.
    If you don't have a dns server, for your .cisco.com network yet, you can contact the .com authorities and ask them to register one or to register the CSS directly [really not recommended as the CSS is very limited it what it can do with DNS].
    So, to answer your question, no an external dns server is not required [you can test this function in a lab without dns server] but in a production environment you will need one.

    Gilles.

  • Problem with DNS - ping/Safari cannot resolve, but host/dig work OK

    Hi All,
    Have a weird problem with DNS which is a bit similar to the following ones:
    http://discussions.info.apple.com/thread.jspa?threadID=2190208
    http://forums.macrumors.com/showthread.php?t=337942
    I connect with remote internal network via OpenVPN and from time to time (yes, intermittent problem :)) internal DNS names cannot be resolved.
    When it happens I can still resolve names using host or dig utilities, but applications (like Safari) and ping cannot resolve them.
    resolv.conf has proper DNS server set:
    *$ cat /etc/resolv.conf*
    *# Mac OS X Notice*
    *# This file is not used by the host name and address resolution*
    *# or the DNS query routing mechanisms used by most processes on*
    *# this Mac OS X system.*
    *# This file is automatically generated.*
    *domain openvpn*
    *search openvpn*
    *nameserver 10.0.0.1*
    More than that - it can resolve those internal names when queried directly, for example using host:
    *$ host YYY.XXX.ru 10.0.0.1*
    *Using domain server:*
    *Name: 10.0.0.1*
    *Address: 10.0.0.1#53*
    Aliases:
    *YYY.XXX.ru has address 192.168.x.y*
    but at the same time ping reports "*Unknown host*":
    *$ ping YYY.XXX.ru*
    *ping: cannot resolve YYY.XXX.ru: Unknown host*
    I tried "*dscacheutil -flushcache*" and it did not help. Also tried to comment out domain and search directives in resolv.conf and it did not help as well (and actually it should not matter).
    Any ideas why this can happen and what else can I check when it happens again?
    Thanks!

    I have the same issue. It cropped up after I installed updates to MS Office 2008 and Firefox in which I also saw issues with the icons disappearing in the dock of the applications that were open when I started the Office update. I rebooted to try to get them back, but ended up deleting them and restoring from the Applications folder. I don't know if that's a red herring or not, but I generally try to figure out what has recently changed that may cause something to suddenly start failing.
    I'd been working successfully all morning before it started acting up. Switching from wifi to cat5 had no effect.
    @realaaa, were you able to resolve without a major undertaking, like reinstalling your OS?

    Hi Bala,
    I want to configure my Database with & without DNS. (Will try both installation in different servers)I think, you have already received a link on very good article about Oracle RAC installation without DNS and DHCP (I mean Jeffrey Hunter's article).
    There is one more about Oracle RAC installation with DNS and DHCP (http://gjilevski.com/2011/10/05/build-two-node-oracle-rac-11gr2-11-2-0-3-with-gns-dns-dhcp-and-haip/).

  • Upgrading: Migration Assistant with FireWire or Time Machine Restore?

    Hello,
    I recently ordered a new Black Penryn MacBook to replace my 17" iMac. Would you recommend using the Migration Assistant with FireWire or a Time Machine restore in order to copy all of my data to the MacBook? I have the option to do both, but am unsure of which would be the best. Is the time machine restore more suited to restore a failed drive as opposed to facilitating a data transfer between two machines? Finally, regarding either of the transfer options, will there be any issues with keychain or application data that I should be aware of? Thanks for your help!

    Those are two of the option presented by Migration Assistant. I think the end result will be the same. If I was doing it, I'd use the FireWire method, just because it's coming directly from the source instead of through a backup archive structure.

  • Please note that i am seeking some assistance with adding the followng resource: A maximum of 4 resources can be added at an additional cost of $500 per day per resource.

    Hi, Please note that i am seeking some assistance with adding the following resource to a task in Microsoft Project 2010:
    A maximum of 4 resources can be added at an additional cost of $500 per day per resource.

    Hi Clemence,
    Your post has quite little details, but as far as I understand, you want to add 4 resources on a task, each resource costing 500$ a day. Since it is not mentionned if it is generic resources (skill or role) or named resources, I'll assume that it is generic
    resources. Based on this understanding, here is a proposal:
    Go to the resource sheet,
    Create a work generic resource ("type" field set to "work", "generic" field to "yes"), typing in the resource name field the skill name,
    In the max unit field, enter 400% for 4 resources (for just 4 if  your Project 2010 is configured to display units in decimals),
    Since the rate is an hourly rate, make the calculation : 500$ per day / 8 hours a day = 62,5$ per hour,
    Go back to the Gantt Chart, split the window (click "detail" in the view tab of the ribbon),
    Select your task and assign the newly created resource with a given % units.
    Hope this helps.

    Need assistance with Windows 2008 R2 server BSOD - ATTEMPTED_EXECUTE_OF_NOEXECUTE_MEMORY (fc)
    I have a Windows 2008 R2 server which is experiencing random BSOD during the night. This is occurring maybe once or twice a week. I have gathered two Memory crash files. This server is running Citrix XenApp 6.5 but nothing else is reporting an issue except
    for the memory dump. I’m looking for assistance in reading crash file and finding the cause.
    I’ve spent over a week going through articles trying to learn and trouble shoot the BSOD but no closer to understanding the WinDbg 6.3.9600 report.
    This is a production server and I have verified that Windows Updates has updated the server with latest releases. I’m hoping that the crash file will show something before I have to run the Driver Verifier.

  • Need Installation Assistance with Photoshop CS6

    Hi there,
    I am trying to install Photoshop CS6 on my Mac Pro running OS X 6.8 using the same installation CD I just used to successfully load it on my new MacBook Pro. The installation quits - tried it three times after restarting twice - and I get the below error message. I would appreciate your assistance with how to address this error and then get the software installed. Thanks! Bruce
    Exit Code: 34 -------------------------------------- Summary -------------------------------------- - 1 fatal error(s), 0 error(s), 0 warning(s)  FATAL: Payload '{9FC6805B-9FD9-410A-A620-51D58644999D} Camera Profiles Installer_7.1_AdobeCameraRawProfile7.0All 6.0.98.0' information not found in Media_db. -------------------------------------------------------------------------------------
    System Requirements

    Thanks for pointing me in that direction. I actually spent over two hours on the phone with tech support this morning and finally got the installation to work. I had to ultimately delete everything Adobe related from my Mac before the install worked.
    Much appreciated!
