Confusion with DNS setup on IPv6

We finally got our IPv6 (dual-stack) circuit installed, so now the real fun begins!
We have IPv6 configured inside (on Fa0/0) and out (Serial0/3/0).  No problems here.
SLAAC works fine as any workstation I plug on the inside network (attached to Fa0/0) autoconfigs itself, just like it should.  If I change the network on the inside interface, the new network (slowly) gets propogated to the workstations--as it should.
So my question is...how are workstations, which SLAAC themselves on the internal LAN, supposed to get DNS server information?
Do I have to manually configure DNS servers on each device?  Seems like a backwards approach -- make getting an IP easier (via SLAAC), but not I have to manually configure DNS on each device.
Can I run DHCPv6 and SLAAC RA concurrently?
I tried to enable DHCPv6 just to hand out name servers, but neither workstations pick up it, and I'm not seeing any DHCP traffic reach the workstations (via tcpdump on the linux workstation).
What does everyone else do?
For the record...I have two workstations in the IPv6 lab; 1) Windows XP, and 2) CentOS 5.5
Thanks.

Russ,
Not sure what your current config is. And I don't want to start a holy flame war of SLAAC and DHCPv6.
One of the approaches is to push either all or some info from DHCP.
Things you should be aware of regarding DHCP/ND/DNS interaction is the O and M flags in ND.
You need to specify to hosts what parameters they should get from DHCPv6.
CA(config-if)#ipv6 nd ?(...)  managed-config-flag     Hosts should use DHCP for address config(...)  other-config-flag       Hosts should use DHCP for non-address config
Not sure if this is something you already have in your config ;-)

  • Help with DNS setup for LAN only

    I have a Mac Mini SNS 10.6.8 as our company's local standalone fileserver.
    Everything has ran great for the past year (still is), but now I want to try and setup DNS for more control and services.
    The server host name is servername (no FQDN), which shows up in Server Admin as servername.local.
    I read and followed Hoffman Labs great step-by-step, but must have missed something, since I still cannot get DNS resolution.
    Here is a brief summary of the Server Admin settings:
              Host Name                    servername
              Host (Server) IP          192.168.4.2
              Router IP (also default public DNS IP) 192.168.4.1
              Bonjour                    Wide Area  =  Not enabled
              Settings                    Accept recursive queries  =  localnets
              Settings                    Forwarder IPs  =  8.8.8.8  &  8.8.4.4  (Google Public DNS)
    now...          Zones                              1 Primary Zone  =  companyname.net (we own the domain)
                                            Primary Zone Name  =  companyname.net
                                            Nameserver Zone  =  companyname.net
                                            Nameserver Host Name  =  servername.companyname.net
                                            2 A Records:
                                            servername          192.168.4.2
                                            user1                    192.168.4.3
                                            Reverse mapping - automatic - OK
    Testing          Ran sudo changeip -checkhostname
                        Results:
                                  Primary address          =          192.168.4.2
                                  Current hostname          =          servername
                                  The DNS hostname is not available. Please repair DNS and re-run this tool.
    I must be doing something wrong, but I don't know what it is.  Please help.

    Did you intend to have both "example.com" and "example.net" listed there?  Are those domains really different?  I'm going to assume that was an obfuscation error.  (This is part of the "fun" of obfuscation, unfortunately.  Of having to differentiate errors in the actual configuration from errors that were introduced during the obfuscation.)
    >Oddly, even though I had manually assigned our Comcast gateway's DNS to Google DNS IPs, the gateway summary still shows up as Comcast's DNS server IPs.  So I removed the manually assigned Google DNS IPs from the gateway.
    The gateway (or whatever you're using as your DHCP server) should be configured with the DNS server address of 192.168.4.2.  All other hosts on your network (if you're planning to use your local DNS everywhere on your LAN) should also reference 192.168.4.2, either through an explicit static configuration, or as the address that was received from the DHCP server.
    And as for IP routing, are all your hosts, network printers, network gateways, DHCP servers, etc., all in the range of 192.168.4.1 to 192.168.4.254?  (They should be, if you're using a /24-class 255.255.255.0 subnet mask.)
    But then I don't know where this configuration has gone off the rails...  (Over the years, I've seen and have made my own configuration errors, I've been "bagged" by DNS caches, and I've hit various bugs in DNS implementations.)  What you have stated here should work.
    I'd start at the top of the DNS configuration article, and not stray from what is written there.   That there has been Google DNS and have had ISP DNS configured at the gateway does mean there were some areas that have strayed from the article.   I'd suggest following the DNS server configuration directions exactly.
    Setting up DNS services with OS X Server isn't difficult, but it can be a little fussy. 
    If you don't understand something that's written in that article -- or if you believe you need to enter something different than what's listed there -- then please stop and ask about it.  Either ask here, or ask over there.  (This feedback also helps improve that article.)
    Straying from what's written in that article is certainly and entirely feasible, but that's something best left until after the adminstrator is more familiar with running a DNS server.  Once you know how and why and where you can stray, there are all sorts of things you can do within a DNS configuration.

  • Multiple Leopard Servers - DNS Setup

    Hi guys,
    Just wandering what I need to do when setting up more than one server on the network with my DNS settings.
    I already have a leopard server box, running advanced with DNS setup and working correctly. How do I setup the second server?
    Do I create a machine record on the original server, as if the new server is just another network device, and not turn on dns on the new server?
    Thanks,
    Nige

    "If you like you can add a NS record for the new machine/DNS name, set the new machine up as a secondary/slave DNS and allow for zone transfers in the first primary/master one. "
    hmm, I think I follow.
    "The second one should use the same forwarders as the first one (both machines should only use itself as the DNS in Network prefpane) and also the LAN reverse zone (*.in-addr.arpa.) should be zone transfered to the secondary DNS."
    Are there instructions on setting up a secondary DNS?
    "In DHCP setup also add the second machine/DNS IP so clients can use either/both."
    I'm not running DHCP on the server, so I'm not sure what I can do here.
    I guess I'll need to do a similar thing with directory as a well, so that both servers have the same users and groups.

  • I need help with proper DNS setup for 10.5.8 Server

    I'm administering a 10.5.8 server that I sold and setup about a year ago. I'm experiencing issues with getting iCal server to be happy. All of the clients are running 10.5.8, but I'm running 10.6.1. I've heard from others that connecting iCal in 10.6 to a 10.5 iCal Server should be no problem.
    I'm beginning to think that I have DNS issues. Probably because I'm not and never have been 100% certain how to set it up completely correctly. I used to be able to get Kerberos tickets, but now I can't. With the new "Ticket Viewer" in 10.6, it asks for two bits of information. First is "Identity" where I'm guessing I should put [email protected] and then password. When I do this I get an alert dialog that says "Kerberos Error -- cannot resolve network address for KDC in realm example.com"
    The server is a Mac Pro tower with two Ethernet ports. En2 is connected directly to the Internet and has a static IP with a domain name assigned to it. We'll call it "example.com" for the purposes of the discussion. The En1 is connected to the network switch and has a static LAN IP of 192.168.1.250. All clients inside and outside are able to reach the server via domain name for WWW & AFP, no problem.
    nslookup on the static IP address returns "example.com" and nslookup on "example.com" returns the correct static IP address. Open Directory is running and happy including Kerberos. The LDAP search base is "dc=example,dc=com". The LDAP search base is a concept I haven't quite grasped, so I'm just going to assume it's correct.
    The domain name is hosted outside by a service provider that forwards all "example.com" requests to the server with the exception of mail.
    In DNS, I have three "sections" that look like this:
    Name Type Value
    1.168.192.in-addr.arpa. Reverse Zone -
    192.168.1.250 Reverse Mapping example.com.
    000.000.00.in-addr.arpa. Reverse Zone -
    000.000.000.000 Reverse Mapping example.com.
    com. Primary Zone -
    mail.example.com. Alias mail.our-email-isp.com.
    example.com. Machine Multiple values
    www.example.com. Machine Multiple values
    NOTE: the zeros aren't actually zeros, they are the static IP assigned to the server/domain
    When I select the top element "1.168.192.in-addr.arpa." down below "Allows zone transfer" is NOT checked. Nameservers shows the zone as "1.168.192.in-addr.arpa." and the Nameserver Hostname as "ns.example.com."
    When I select the next line down "192.168.1.250", Resolve 192.168.1.250 to: example.com.
    When I select the "000.000.00.in-addr.arpa." element, it has the same settings -- nameservers "000.000.00.in-addr.arpa." and "ns.example.com."
    When I select the next line down (our static IP), Resolve 000.000.000.000 to: example.com.
    When I select "com." the admin email is populated with a valid email address, Allows zone transfer is NOT checked. In nameservers, Zone is "com." and Nameserver Hostname is "example.com." The mail exchangers are mail2.our-email-isp.com. priority 10 and mail.our-email-isp.com. and priority 20.
    When I select the machine "example.com." it shows both the real-world static IP and the 192.168.1.250, same with "www.example.com.".
    Am I doing something wrong with this setup? Should "com." be the primary zone or should that be "example.com." ???
    I've been thinking about getting rid of the DNS entry for the 192.168.1.250 address altogether, but will the clients in the office suffer performance issues??? I do not think that the client workstations are configured to get DNS from the server anyway. Should the "www.example.com." record be a Machine record or should it be an alias record?
    Any help you have to offer is greatly appreciated! Thanks!
    In the meantime, I'm going to look around and see if I can understand "Allows zone transfer" and LDAP Search base a bit better.

    Okay, I found a lovely article at the following address which I think helps me to clarify what I'm doing wrong. Despite that, I'd still like to have any feedback you have to offer.
    http://www.makemacwork.com/configure-internal-dns-1.htm
    Also, when editing DNS entries, Server Admin likes to set the nameserver to "ns." -- whatever your domain is. Should I be overriding that and if so, replace it with what?

  • Help with Proper DNS Setup for Leopard Standard Server Setup

    Hello All,
    Problem Description-
    I was reviewing some training today on DNS setup and checking for proper setup with the sudo changeip - checkhostname tool and I seem to have an incorrectly configured DNS setup. So I need some help on correcting it. When I go to the "Server Preferences" tool I cannot log in using apple.ourdomainname.com instead in order to use the tool I have to input localhost as the server name. Now I just thought that the system was broken or something and with the help of my training I now see it's a DNS problem. I thought I had everything proper since I followed the steps of creating proper DNS/RDNS entries with my ISP. Now I am stuck wondering what else isn't working properly due to the DNS issue. Thanks in advance.
    Technical Info-
    My ISP provides us with 5 static IP's and we have asked them to create entries and verified the setup of apple.ourdomainname.com = x.x.x.x which is one of our public IP's assigned currently assigned to the WAN port of our Apple Airport Extreme. We have also had them create a PTR record which also is present, verified and functional. Our MacMini running 10.5.5 is connected directly to one of the ethernet ports on our Apple Airport Extreme which is our NAT/Firewall for the LAN. So during the setup of the Standard Server install the OS configured the Airport with the required ports for chat/web/vpn. And mobile Mac's can VPN in and gain folder access and web works fine too. We don't use the e-mail portion so I can't say how that works. The server is using the DNS of 10.0.200.1 which is the IP of the Airport and the airport is programmed with the DNS of OpenDNS servers 208.67.222.222 and 208.67.220.220. The reason for this whole long shpeal is that I want to give as much technical background as possible for the best possible help.
    Thanks

  • WRT610N incorrect DNS setup using DHCP with 1.00.03.15

    I just noticed this last night and probably could explian my poor network performance since upgrading to firmware 1.00.03.15.
    All of my computers using DHCP, both wired and wireless, Vista & Linux, show DNS1 as 192.168.1.1 or the routers IP address.  I know that 1.00.03.15 fixed a DNS vulernability, but I can't believe this is by design.  Looks like another bug to me. 
    I reverted back to 1.00.2.10 for now, problem goes away.  Hopefully the performance will improve.
    Anyone else experience this?

    Spoke too soon.  Firmware 1.00.02.10 also experiences incorrect DNS setup when using DHCP.  I upgraded back to 1.00.03.15 and set the static DNS ip address on the main router setup page.  Seems to be working.  Hopefully Time Warner doesn't change there DNS ip address that often.

  • 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.
    Regards,
    Gilles.

  • Web access grinds to a Halt with DNS

    Hi
    I have an issue on two site sites now so I know it is something I have or have not done.
    Running OD and DHCP and DNS
    10.5.3 but was happening on 10.5.2
    The clients first port of call is the server itself for DNS requested then external. In the DHCP setup it dishes out the ip address of the server first then the external DNS.
    The web access gets slower and slower then stops and then after about 2 mins speeds up again. the router is the same as before and the only thing that has changed is the DNS setup.
    help please as I have two unhappy servers.
    only two mobile accounts running so not overloading it. G5 dual 2.8ghz with 4gb ram
    many thanks

    Hi Charles!
    First you have no idea what a life saver you will be for me this weekend! I am in LA and the client is in NYC (working remotely obviously) and I've managed to mess things up a bit more since my last post.
    One issue I had with changing the port order is that I loose connectivity to the server and then cannot reboot -- I had my business partner in NYC there to do that for me but he is now gone for the day. Is there a way to avoid this problem? Also, just FYI, I had my partner leave the install DVD in the Xserve drive just in case I needed to do a complete reinstall.
    Now I will also try to answer your questions as best I can:
    Has the server been set up as an Open Directory Master yet?
    Yes it has.
    Hopefully it says dc=server,dc=businessname,dc=pri If not or if it says something like dc=<bonjour-servername>,dc=local.
    It says:
    dc=server,dc=businessname,dc=pri
    Hopefully you haven't already created a bunch of users in Work Group Manager in the LDAP domain
    I have set up users in Work Group Manager but I can easily re-create them. In fact one issue is that they cannot login to AFP services (after I started messing around today), getting SACL membership failures.
    Have you already run the Gateway setup assistant
    I haven't yet but the person that first set up the server may have way back when.
    From your posting I'm assuming the clients will be using internal IP addresses in the 10.10.10.(2-254) range. Correct?
    DHCP clients are currently set in the .100 - .200 range.
    Is this server going to also be the DHCP server for the subnet?
    Please forgive my ignorance but I don't (I know I should) understand the question. Can you explain?
    What all services will this server be providing for the internal network?
    They are: AFP, DHCP, DNS, Firewall (which I'm sure could be better configured), FTP, NAT, OD, SMB and VPN.
    Currently, all clients can access the Internet though cannot access the Server itself (again, probably due to my mucking around today) via AFP or SMB. I do, however still have VPN access.
    Also, FYI, apparently a virtual port was configured also on en0 (I believe the Virtual port was there because at one point both the new and old server were active at the same point and the port forwarded requests to the new server so that we didn't have to change anything on the client side). Anyway, here is the System Profile for both ports on en0:

  • DNS Setup for Lion.

    I'm a little confused with the DNS setup for Lion Server.
    My scenario is this.
    I have a router, IP 10.0.0.1.
    Server running DNS is manually set to 10.0.0.253.
    FQDN for the server is server1.mycompany.net (it is proper registered and live domain name I have used)
    Externally I use Dyndns to point external folks to mycompany.net, and through the correct ports I can hit the router/gateway with the URL. This confirms that Dyndns is working.
    I have forwarded POrt 80 on the router to 10.0.0.253.
    Currently I have set DNS to have a zone of mycompany.net. Within the zone I have a machine record server1.mycompany.net set to 10.0.0.253
    I think I have set the reverse lookup correctly, but the way it is shown in the DNS record looks strange (IP address looks backwards and says something about ARPA.
    Web Server is running on the server.
    Currently if I go to a web browser inside the LAN and use either www.server1.mycompany.net or www.mycompany.net (or the same without the www) I get an error message. The same occurs outside the lan on an internet connected machine.
    If I enter 10.0.0.253 from inside the lan, I get the Mac WebServer default screen, showing the server is working fine.
    I'm guessing I have made a mess of setting up DNS.
    I'm looking at some point set up a small website, just to prove to myself I can get this working, but I can't work out what I have done wrong.
    Can anyone suggest where to look?
    TIA

  • DNS Setup/View external website internally

    Greetings all - trying to set up a Mac server from scratch for the first time. Been managing one for a while but didn't actually set it up myself.
    I have the beginnings of DNS setup all squared away, but am still looking to figure out how to properly set up my website. Here's my setup. We used to have a joint Windows 2003/10.5 server environment. Windows handled Exchange and DNS, the Leopard box handled everything else (DHCP, web, file sharing, etc). We're transitioning everything to the Mac box in preparation for setting up Kerio MailServer and just to ditch the windows box.
    I own companyname.net - that domain is hosted externally by Network Solutions. It's forwarded to my static IP.
    Our old internal DNS was hosted by a Windows 2003 box - it had zones for companyname.ltd (the private internal domain) and companyname.net. companyname.ltd was the nameserver. There were two A records handling the website for internal clients - one with a blank name, and one with www. Both pointed to the IP of the Mac server (the current box that I'm transitioning everything to). Everything was hunky dory - internal pings to the web address went to the internal ip, externally it went to the external IP, and everything worked just great.
    So in setting up the new DNS on the Leopard box, here's what I have so far.
    Primary zone: companyname.net
    A Record: macpro : 192.168.1.3 (this is the name of the server)
    A Record: mail : 192.168.1.2 (our mail server)
    Alias : ichat : macpro.winstongroup.net
    The checkhostname thing works fine, Kerberos is up and running, as is Open Directory.
    Now, I do not know how to set up our website so that internal clients can view the external website. I tried creating an A record to the server for www, but then that overrides the macpro A record that is the host of the whole thing. I also tried creating A records to the external IP, but then when I pinged it just pinged once, then it seemed like the firewall kicked in and stopped it. I tried creating aliases to companyname.net but every time I did that, Server Admin kept adding on an additional companyname.net to the end of the name (so it would read like companyname.netcompanyname.net). That didn't make much sense to me.
    I'm sure there's other people who can view internally hosted sites from the lan - so any help would be very much appreciated!

    One minor other question. I prefer the url of our site to be companyname.net instead of www.companyname.net. So now, while www is set up as a server alias, it wouldn't direct to companyname.net, even though that URL was set up in the web services panel in Server Admin. I then created a new alias that was "companyname.net", without the trailing period so it was not a FQDM, directed it at the same web server, and everything seemed to work. Does that seem right - it's working, so it seems to be somewhat right at least!

  • Applications sending ipv6 dns queries, but ipv6 is disabled

    Hi,
    I had some problems with dns lookups a long time ago and so I followed every hint I could find here in the forums and the wiki, like disabling ipv6, installing dnsmasq, and so on. Firefox and other typical internet applications worked like a charm after that.
    Pacman instead took a long time to lookup the ip for the chosen mirror url, but I didn't bother to look deeper into this issue, until now.
    Wireshark revealed that the dns query that is sent by pacman (and some other console applications like w3m, wget, but not lynx ...) is an AAAA query for an ipv6 address. In spite of ipv6 being disabled.
    Additionally my router (which is added in /etc/resolv.conf) ignores the query, it times out, and after 5 seconds, the AAAA query is sent again.
    This happens 4 times and then a query for the A record is sent which is answered promptly.
    (A simple "w3m google.com" takes up to 1min 20sec with all the lookups following the 301 and 302 answers...)
    Well, a workaround for this is obvious. I could use a nameserver that answers the AAAA query, which I already tried with the opendns server.
    But the question that I have is: Why are some applications sending dns queries for ipv6 addresses although ipv6 is disabled?
    Regards,
    Marc

  • Basic DNS Setup

    Heya Guys,
    I'm new to server and in need of a little bit of help.
    What I want to do is run a mail server (kerio) on my Mac Mini which is now running 10.5 server. I need to configure my server to run DNS but I'm not to sure on how to do it.
    My setup is,
    Static IP - Netgear Router - Mac Mini (DNS & Mail Server)
    Is someone able to out line a basic DNS setup for me so I know what I'm doing? Maybe using my domain name as example.com
    Cheers,
    Dave.

    Hello Tim
    +" . . . why would you use kerio mail server when leopard server includes a Mail server? . . ."+
    One reason is the built in Mail Service is not everyone's cup of tea. If you want to effectively use it you have to use to command line. Not everyone wants to do that. If you want out of office replies you have to bolt on something else. Same with an effective backup. If you want to use a unified address book and calendar you have to bring other applications into play. There is nothing wrong with any of that but if you want simplify ease of use and provide something that is an all-in-one solution then Kerio is pretty hard to beat.
    One of Kerio's features is its ability to remotely wipw mobile devices (Blackberries etc) if they have been lost or stolen. I can't find that feature anywhere in the Mail Service. It literally takes only an hour (including download) to get it secured and running all from an extensive but user friendly interface that works. If a group member receives a reply the other members in the group get to know and therefore have no need to reply in turn. I could go on. OK it can start to get expensive as you add more users and also because of the virus subscription, but it can be made to use OSX Server's built in AV and Anti-Spam filters. Neither do you don't need to install it on a Server box. Any client OS will do. All of its features can be accessed using the built-in webmail client supported by all the main browsers. For PC users in a mixed platform environment it behaves in the same way an Exchange Server does.
    It has its own built-in Archive and Backup Feature that does not involve stopping the Mail Service in any way. Its pretty good when you need to restore as well. From an administrative point of view it is as close to click and forget as you can get.
    Don't get me wrong I like Apple's Mail Server - I like the challenge. But given the choice and budget I would go for Kerio every time.
    Just an opinion.

  • E4200v2 on .37 firmware bricked by setting new port address with DNS off

    I hooked up my E4200v2 with the intention of replacing another router, with DNS off. While everything else was disconnected, I used a wired interface to change its address to 192.168.0.1 on the first setup page.  As soon as I pressed "Save Settings", the darned thing turned off all of its ethernet ports and lay dead.  I performed a 30on-30off-30on reset, but the darned thing wouldn't wake up.  I let it sit for a half hour and tried again, with no luck.   I tried again an hour later, and suddenly the Cisco light began to blink. I quickly hooked up my PC to the wired local port, and set my PC's wired interface statically to the new subnet. No luck. Then I tried the original subnet. No luck.  Then suddenly the ports went dead again, never to return to life, despite patient waiting followed by another attempt to 30on-30off-30on reset.  What gives?  Is there some fatal firmware flaw?  Has no one out there done this before?  This router is only about 4 months old.  Is there another reset mode?  It's like the settings poisoned it.  The Cisco light is on solid, but no recovery.

    You can hard reset the router. Try isolating it using a loop back test or use another Ethernet cable if necessary. If LAN status says, media disconnected then I think you can call tech support for replacement.
