• Why is BIND giving me a SERVFAIL in this case? (Notes inside)

  - by imaginative

  Woke up this morning to a bunch of the following: root@foo:/etc/bind# dig @1.2.3.4 foo.example.com ; <<>> DiG 9.6.1-P2 <<>> @1.2.3.4 foo.example.com ; (1 server found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 36121 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;;foo.example.com. IN A ;; Query time: 0 msec ;; SERVER: 1.2.3.4#53(1.2.3.4) ;; WHEN: Thu Apr 1 09:57:59 2010 ;; MSG SIZE rcvd: 31 Some background on the fictitious "1.2.3.4". It's a slave name server in my nameserver "farm". Technically I have ns1 (being the master) and ns2/ns3. Currently ns1/ns2 are down for maintenance, so I left ns3 at it serving live traffic. That's the point, DNS is supposed to be resilient. Now the odd part is, "1.2.3.4" was serving requests for example.com just fine for the last 4-5 days. This morning I get a phone call that it's non-responsive. After investigation I see the message you see above, SERVFAIL. I looked into the zone file and saw the following: example.com IN SOA ns1.example.com. hostmaster.mail.example.com. ( I wondered if at this point that the nameserver thought it was not authoritative over example.com and adjusted it to the following: example.com IN SOA ns3.example.com. hostmaster.mail.example.com. ( After that, it started responding again for all authoritative queries for example.com. I have no idea why. I thought these things were supposed to be normalized upon zone transfer from ns1 - ns3? Can someone please example why this happened and how to prevent it from happening in the future? I've never had a similar problem, and because I don't understand it well, I might be missing some critical information in this question. So please let me know if I can further add any detail to make things clearer as well. One more thing to note: I have other domains that I'm authoritative for that have their SOA still saying ns1.example.com. and not ns3.example.com. Those domains are serving requests just fine! Is it a matter of time before they stop also and I have to change SOA to ns3.example.com? Is this also only required because ns1 and ns2 are currently offline?

• Reliable access to Internet but not local network (not DNS or proxy issues)

  - by Ian Goldby

  I'm looking for help with a Vista Home Premium laptop that has trouble accessing any resource on our home network, but accesses the Internet just fine. The set-up is this: The Vista laptop and a MacBook Pro connect wirelessly to the router-modem. A Synology DS212j NAS drive has a wired connection to the router-modem. Devices on the local network are always referred to by IP address, so this cannot be a DNS issue. The MacBook Pro connects reliably to the NA via AFP (network shared folders), SMB (network shared folders) and HTTP. The Vista laptop connects to and browses sites on the Internet without any problems. It can log into the NAS via SMB and list the shared folders (so there is nothing wrong with the log-in credentials), but when it tries to open any of the folders Explorer just hangs with the spinning cursor for several minutes and then says "\192.168.1.64\shared\Photos is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions. The specified network name is no longer available." It can ping the NAS successfully. If I try to open the NAS drive's web interface, the browser just hangs. This is the same with IE, Firefox and Chrome. (There is no proxy.) I can log into the NAS drive with FTP and navigate directories, but when I try to list the contents of a directory with more than a handful of entries, the ftp client hangs. I set up a website on the MacBook. The Vista laptop was able to load some of the pages, but loading any of the images was very hit and miss. Images embedded in HTML pages never worked no matter how many times I reloaded the page, but when I linked directly to the image it did load (though several attempts were sometimes needed). I tried all of this with the Windows Firewall turned off, and with AVG turned off. That made no difference. I'd really appreciate any suggestions anyone can make. The fact that the Vista laptop has trouble with HTTP and FTP as well as SMB connections suggests to me that this is a problem at the TCP level or below. But don't forget it accesses sites outside the LAN with no problems.

• Single domain name potentially resolving to multiple servers

  - by Jace

  first time here at Server Fault, and I apologize in advance that this domain stuff is not really my strength. Any and all suggestions are much appreciated. I am completely lost and incredibly tired! I've inherited an incredibly convoluted system from my predecessor, and I'm trying to find a way to solve it - or I need to be told that it just isn't possible. I've got an old site on ServerA (some kind of Linux distribution), with the domain SomeDomain.com There is a new site sitting on ServerB (Ubuntu), with the intention of having SomeDomain.com to serve it in the future (it is replacing the old site) ServerA also has a web app that is currently in use by other departments within the company (accessible at SomeDomain.com/web-app/) The goal: To have SomeDomain.com and all extensions of this domain name (sub-domains, URL's etc.) serve the new site on ServerB. BUT, the URL SomeDomain.com/web-app/ must serve the Web App on ServerA. The Catch: The ServerA is a shared server with a hosting company with VERY limiting restrictions in place - I cannot adjust DNS settings (apart from Name servers - but cannot set A records or anything, I have full access to ServerB to do as I wish). Therefore the web-app MUST be served from SomeDomain.com/web-app/ and not from a sub-domain or anything. These limitations make migrating the web-app from Server A to Server B rather undesirable, AND this web-app will be replaced in the near future, so it isn't worth the effort right now. Therefore, ultimately I will want 1 domain name to resolve to Server B's IP address most of the time, but in the event that the URL is SomeDomain.com/web-app/, it should resolve to Server A's IP. Note: The domain names don't, technically, have to resolve to one IP or another - but ultimately the URL's must stay consistent Some things I have tried: I've looked into mod_rewrite and .htaccess to try and achieve this effect, but it doesn't look like it's going to work for me - but I may have done it wrong (On Server B, I just checked if the request URI was /web-app/ and tried to serve the /web-app/ folder on Server A) I do have the ability to modify the name servers on both servers I am not able to make a sub domain on Server A that points back to Server A (I assume because the hosting company's servers use the URL to determine what site the serve). I figured this could be good as I'd could set an A record on Server B to point to the web app on Server A - but alas, Server A requires SomeDomain.com. If there is any more information I can give, please let me know. I need a nudge in the right direction, ideas or a solution.

• Email forwarding from my domain to gmail - FAIL

  - by pitosalas

  [There are numerous similar questions on ServerFault but I couldn't find one that was exactly on point] Background: I use Gmail for my email client. My email is [email protected]. However the email that people communicate to me with is [email protected]. I run the server that hosts www.example.com and other domains, at ServerBeach. Up to yesterday, I had SENDMAIL painlessly just forward emails to [email protected] to [email protected] and everything was fine, for several years in fact. Suddenly my email stopped working - that is, my gmail account stopped receiving emails via the forward from my server. Looking into it I found a bunch of emails sitting on my server with content like this: ... while talking to gmail-smtp-in.l.google.com.: RCPT To: <<< 450-4.2.1 The user you are trying to contact is receiving mail at a rate that <<< 450-4.2.1 prevents additional messages from being delivered. Please resend your <<< 450-4.2.1 message at a later time. If the user is able to receive mail at that <<< 450-4.2.1 time, your message will be delivered. For more information, please <<< 450 4.2.1 visit xxxxxx://mail.google.com/support/bin/answer.py?answer=6592 u15si37138086qco.76 [email protected]...

But I don't know really what's going on nor do I see whatever emails might be involved. I've read stuff on zoneedit.com that sounds like they might have a solution in their service for what I am trying to do. I also read a lot about admining DNS and SENDMAIL and tried various things, but nothing works. Can you tell from my description what is going on that caused GMail's server to stop accepting email from my server and is there a way to stop it? What is the 'correct' way to configure things so that emails to [email protected] behave as if they were sent to [email protected]? Thanks so much!

• Too many Bind query (cache) denied, DNS attack?

  - by Jake

  Once Bind crashed and I did: tail -f /var/log/messages I see a massive number of logs every second. Is this a DNS attack? or is there something wrong? Sometimes I see a domain in logs like this: dOmAin.com (upper and lower). As you see there is only one single domain in the logs with different IPs Oct 10 02:21:26 mail named[20831]: client 74.125.189.18#38921: query (cache) 'ns1.domain2.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 192.221.144.171#38833: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 74.125.189.17#42428: query (cache) 'ns2.domain2.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 192.221.146.27#37899: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 193.203.82.66#39263: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 8.0.16.170#59723: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 80.169.197.66#32903: query (cache) 'dOmAin.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 134.58.60.1#47558: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 192.221.146.34#47387: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 8.0.16.8#59392: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 74.125.189.19#64395: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 217.72.163.3#42190: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 83.146.21.252#22020: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 192.221.146.116#57342: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 193.203.82.66#52020: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 8.0.16.72#64317: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 80.169.197.66#31989: query (cache) 'dOmAin.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 74.125.189.18#47436: query (cache) 'ns2.domain2.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 74.125.189.16#44005: query (cache) 'ns1.domain2.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 85.132.31.10#50379: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 94.241.128.3#60106: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 85.132.31.10#59118: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 212.95.135.78#27811: query (cache) 'domain.com/A/IN' denied /etc/resolv.conf ; generated by /sbin/dhclient-script nameserver 4.2.2.4 nameserver 8.8.4.4 Bind config: // generated by named-bootconf.pl options { directory "/var/named"; /* * If there is a firewall between you and nameservers you want * to talk to, you might need to uncomment the query-source * directive below.

• 1 domain.. 2 server and 2 applications

  - by basit.

  i have a site like twitter.com on server one and on server two i have forum, which path is like domain.com/forum on server one i wanted to implement wild card dns and put main domain on it. but on server two i wanted to keep forum separate, i cant give sub-domain forum.domain.com, because all its links are already put in search engines and link back to domain.com/forum. so i was wondering, how can i put domain and wild card dns on server one and still able to give path on server 2 for domain.com/forum (as sub-folder). any ideas? do you think htaccess can do that job? if yes, then how?

• How would I / could I obtain an reasonably comprehensive list of domain names?

  - by Simon

  I know that domain names are constantly changing, and I know there are a lot of them, but there is clearly a region of the domain name space which is stable. How would I go about getting a list, even a very big one? Such a thing must logically exist, even if it is in a distributed form, because the web's DNS servers resolve names to IP addresses. So in theory if I could poll all the DNS servers in the world at a moment in time I would have the complete list of mapped names. Is there a practical way of doing that? As an aside, does anyone have any good estimates of how many domain names exist at the moment?

• Future proofing client-server code?

  - by Koran

  Hi, We have a web based client-server product. The client is expected to be used in the upwards of 1M users (a famous company is going to use it). Our server is set up in the cloud. One of the major questions while designing is how to make the whole program future proof. Say: Cloud provider goes down, then move automatically to backup in another cloud Move to a different server altogether etc The options we thought till now are: DNS: Running a DNS name server on the cloud ourselves. Directory server - The directory server also lives on the cloud Have our server returning future movements and future URLs etc to the client - wherein the client is specifically designed to handle those scenarios Since this should be a usual problem, which is the best solution for the same? Since our company is a very small one, we are looking at the least technically and financially expensive solution (say option 3 etc)? Could someone provide some pointers for the same? K

• Adding an host programmatically (name resolution under Windows)

  - by Tanelorn

  I would like to programmatically add to Windows a name / IP association so that this name can be resolved locally. This does not have to be persisted between reboots. The only way I now is to add an entry to the "hosts" file, but this feels hacky especially since I would like to automate this. Is there any way to do this using a command-line tool or a Win32 API? Perhaps by addind an entry to Windows DNS cache or something similar? Oh, and please state if this solution is Vista-compatible. Regards. Edit : Thanks, guy. Sadly, all of your answers indeed involve DNS or other servers. I was looking for a purely local solution which would work on a "standard" Windows installation. Such a thing does not seem to exist, though.

• NServicebus DNS Entry for Machine location

  - by Paul Oakham

  Hi Guys, I am trying to use a DNS entry for my NServicebus queue endpoint but no messages are being sent. It works fine when I enter the computer name or an IPAddress. I can ping the record and it resolves correctly so i'm wondering if it is possible to use a DNS record? Here is my config: <MessageEndpointMappings> <!--These are the messages which need to be sent to the BusService --> <add Messages="BusCommon.BusHeartBeatMessage, BusCommon" Endpoint="[email protected]" /> </MessageEndpointMappings> Thanks

• How to host a naked domain on a CDN?

  - by rjw79

  If I have a domain that I wish to serve "naked" eg http://examp.le/, and efficiently with a CDN, what are my options? The issue is that the CDNs I looked at all want you to use a CNAME so that they can do geo ip lookup. CNAMES are not meant to be served at the same level as other records, and this apparently breaks some dns resolvers. You at least need SOA and MX records at the same level for a naked domain. The only solutions are: having A records in your own dns, thus skipping the geo ip, or finding a cdn who will allow delegation of the whole domain so they can do geo ip things for the A record directly. I've tried googling and can't find any Cdn who offers this. Any ideas? I looked closely at Amazon cloudfront and rackspace cloudfiles. I couldn't work it out for those.

• cannot access a site from Mac OSX Lion but can from other machines on network?

• Messenger Thinks My Ip is Invalid

  - by Umut Benzer

  Hello. I am using Windows Live Messenger 2009 on Windows 7. I am using a 3G modem (ZTE Propietary USB Modem) I connect to the Internet using a software my ISP provided me. In last three days, my Messenger started to disconnect. Here is what I observed and tried to do: 1- I can browse web, can do FTP transfer etc. and obiviously have a valid IP. 2- I can sign in to Messenger (appear offline) but when I change my status to anything other then appear offline, Messenger says my connection to service has been lost. (However, it exists.) 3- When I run, MSN Connection Troubleshooter, it says my IP is invalid. When I click repair, it says repaired and just after that, I run the troubleshooter again, and it says my IP is invalid again. (However, it is valid and I am browsing the net.) 4- If I connect the Internet through eterhet or wireless there is no problem at all. 5- I re-installed Messenger (deleting all settings manually through registry and folders), re-installed all drivers and software related to USB 3G Modem. It doesn't work. And then, I took a full backup then formatted entire computer, installed a fresh windows 7, after 5 minutes, the same problem occured. What do you recommend? What can I do? Addition As seen on screenshot, it says Server IPv4 adress is 0.0.0.0 It seems like a problem, I don't know if it is. If it is, how can I solve it? Here is what I get, when I netstat.

• WCF client endpoint identity - configuration question

  - by Roel

  Hi all, I'm having a strange situation here. I got it working, but I don't understand why. Situation is as follows: There is a WCF service which my application (a website) has to call. The WCF service exposes a netTcpBinding and requires Transport Security (Windows). Client and server are in the same domain, but on different servers. So generating a client results in the following config (mostly defaults) <system.serviceModel> <bindings> <netTcpBinding> <binding name="MyTcpEndpoint" ...> <reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="false" /> <security mode="Transport"> <transport clientCredentialType="Windows" protectionLevel="EncryptAndSign"/> <message clientCredentialType="Windows" /> </security> </binding> </netTcpBinding> </bindings> <client> <endpoint address="net.tcp://localhost:xxxxx/xxxx/xxx/1.0" binding="netTcpBinding" bindingConfiguration="MyTcpEndpoint" contract="Service.IMyService" name="TcpEndpoint"/> </client> </system.serviceModel> When I run the website and make the call to the service, I get the following error: System.ServiceModel.Security.SecurityNegotiationException: Either the target name is incorrect or the server has rejected the client credentials. ---> System.Security.Authentication.InvalidCredentialException: Either the target name is incorrect or the server has rejected the client credentials. ---> System.ComponentModel.Win32Exception: The logon attempt failed --- End of inner exception stack trace --- at System.Net.Security.NegoState.EndProcessAuthentication(IAsyncResult result) at System.Net.Security.NegotiateStream.EndAuthenticateAsClient(IAsyncResult asyncResult) at System.ServiceModel.Channels.WindowsStreamSecurityUpgradeProvider.WindowsStreamSecurityUpgradeInitiator.InitiateUpgradeAsyncResult.OnCompleteAuthenticateAsClient(IAsyncResult result) at System.ServiceModel.Channels.StreamSecurityUpgradeInitiatorAsyncResult.CompleteAuthenticateAsClient(IAsyncResult result) --- End of inner exception stack trace --- Server stack trace: at System.ServiceModel.AsyncResult.End[TAsyncResult](IAsyncResult result) at System.ServiceModel.Channels.ServiceChannel.SendAsyncResult.End(SendAsyncResult result) at System.ServiceModel.Channels.ServiceChannel.EndCall(String action, Object[] outs, IAsyncResult result) .... Now, if I just alter the configuration of the client like so: <endpoint address="net.tcp://localhost:xxxxx/xxxx/xxx/1.0" binding="netTcpBinding" bindingConfiguration="MyTcpEndpoint" contract="Service.IMyService" name="TcpEndpoint"> <identity> <dns /> </identity> </endpoint> everything works and my server happily reports that it got called by the service account which hosts the AppPool for my website. All good. My question now is: why does this work? What does this do? I got to this solution by mere trial-and-error. To me it seems that all the <dns /> tag does is tell the client to use the default DNS for authentication, but doesn't it do that anyway? Thanks for providing me with some insight.

• Repeated host lookups failing in urllib2

  - by reve_etrange

  I have code which issues many HTTP GET requests using Python's urllib2, in several threads, writing the responses into files (one per thread). During execution, it looks like many of the host lookups fail (causing a name or service unknown error, see appended error log for an example). Is this due to a flaky DNS service? Is it bad practice to rely on DNS caching, if the host name isn't changing? I.e. should a single lookup's result be passed into the urlopen? Exception in thread Thread-16: Traceback (most recent call last): File "/usr/lib/python2.6/threading.py", line 532, in __bootstrap_inner self.run() File "/home/da/local/bin/ThreadedDownloader.py", line 61, in run page = urllib2.urlopen(url) # get the page File "/usr/lib/python2.6/urllib2.py", line 126, in urlopen return _opener.open(url, data, timeout) File "/usr/lib/python2.6/urllib2.py", line 391, in open response = self._open(req, data) File "/usr/lib/python2.6/urllib2.py", line 409, in _open '_open', req) File "/usr/lib/python2.6/urllib2.py", line 369, in _call_chain result = func(*args) File "/usr/lib/python2.6/urllib2.py", line 1170, in http_open return self.do_open(httplib.HTTPConnection, req) File "/usr/lib/python2.6/urllib2.py", line 1145, in do_open raise URLError(err) URLError: <urlopen error [Errno -2] Name or service not known>

• Website hosting from home - IIS6 [closed]

  - by Paul

  I'm wanting to host a few websites from home, primarily because I'm using some BETA Microsoft software (.NET 4 and EF) and don't want to install it on my production server which is hosted at eukhost.com. Basically, I'm completely new to this sort of thing. So far, here is what I've done: Registered the domain name at namecheap.com (let's call it mydomain.com) Gone to "Nameserver Registration" in the panel and entered my IP address for the NS1 and NS2 records (let's say the IP is 0.0.0.0). Gone to "Domain Name Server Setup" and entered ns1.mydomain.com & ns2.mydomain.com Forwarded requests from port 80 to my internal IP (let's say 192.168.1.254) Created the website in IIS (I'm just testing with a single website so far, so have not created any host header values) Now, if I type in the IP address (http://0.0.0.0) I get the site as expected. However, if I enter http://www.mydomain.com I get an error saying "DNS Error - Cannot find server". I'm aware that there is a service from DynDNS that will automatically change the IP if I have a dynamic address, however my IP has remained static since I installed the ISP (since October) so I don't need this. Is there any way that I can get the DNS to work just by configuring IIS or something in Windows? I don't really want to have to pay for any 3rd party service. Thanks,

• iptables is not allowing me to contact my dns nameservers

  I have the follwing iptables rules: Chain INPUT (policy DROP) target prot opt source destination ACCEPT tcp -- anywhere anywhere tcp dpt:ssh ACCEPT tcp -- anywhere anywhere tcp dpt:http ACCEPT tcp -- anywhere anywhere tcp dpt:https ACCEPT tcp -- localhost.localdomain anywhere tcp dpt:mysql ACCEPT tcp -- anywhere anywhere tcp dpt:14443 ACCEPT tcp -- anywhere anywhere tcp dpt:ftp ACCEPT tcp -- anywhere anywhere tcp dpt:ftp-data ACCEPT tcp -- anywhere anywhere tcp dpt:xxxxxxx Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination When I turn off iptables I am able to use wget and all other commands. When these rules are enabled I cannot connect to any address. Any idea why this would be?

• How do I install and use the cli53 tools on Windows?

  - by pavlos

  I'm trying to find the simplest way to import a large number of BIND zone files in to Route 53. I've had a quick look at the AWS CLI and AWS Tools for Windows PowerShell but they don't seem to include a zone file import option like the AWS Route53 GUI does. The cli53 utility on the other hand does, but is written in Python and appears to have a series of pre-requisites to get going which I'm having troubles working out for Windows. I can find plenty of examples of setting it up under Linux but only one reference to a PowerShell example here, but it doesn't explain how to install cli53 in the first place. The other option I'm exploring is to use the BIND to Amazon Route 53 Conversion Tool perl script to first convert the zone files to the Route53 CreateHostedZoneRequest XML format and then use the AWS New-R53HostedZone PowerShell cmdlet to import the zones. After the zones have been imported I'll be looking at running a script to validate what has been created in Route53 matches with the existing nameserver prior to updating each domains nameserver records - I was planning on whipping something up using the new PS4.0 Resolve-DnsName cmdlet, but let me know if you have any better suggestions. Any assistance would be greatly appreciated - thanks. (By the way, I had more reference links in my post but ServerFault won't allow me to post more than 2 links being a new member; and for this same reason I also can't comment on Vasili's example in the other linked thread)

• Getting mydomain.com/subdomain to resolve to subdomain.mydomain.com

  I have content on subdomain1.mydomain.com which can't reside on mydomain.com/subdomain1. Nevertheless, all my other content resides in folders of the mydomain.com/subdomain* type. For the sake of consistency, I'd like the content actually located at subdomain1.mydomain.com to appear as if it were on mydomain.com/subdomain1 — Is there any way, using .htaccess, that I can achieve this, bearing in mind that: (1) the subdomain itself also has a nested permalink structure, meaning that there are additional folders in the directory structure of the subdomain; (2) I want the browser to display the address as mydomain/subdomain1 after the redirect.

• Hosting 2 Sites Under 1 DiscountASP.Net Hosting Account

  - by Gav

  I've currently got an ASP.Net site hosted with DiscountASP.Net what I would like to do now is put a second site in a subdirectory of this original site and register a new domain to point at the subfolder, so to the end user its 2 completely seperate sites. I've asked DiscountASP support if they could do this and they just say they dont support it and wont help. If I registered the second domain with someone like 123-reg is it possible to make that domain point to a subdirectory in my main site? If not I may have to put some sort of redirect on my route index page that sends you to the right page based on the URL you requested but I would really rather not have to go there. I don't want to buy an additional account as the second site is just a bit of a side project that may well go no where.

• What's required for a nameserver to be registered?

  - by Lin

  I'm trying to change nameservers for some of my domains at GoDaddy, but I occasionally run into "Nameserver not registered" problems, and then I'm not allowed to set the nameservers. Here are the cases I've tried, and I still don't understand what it takes to have a registered nameserver. With ns1 and ns2 pointing to my nameservers, I can set the nameservers successfully when I set up domains as follows: Host Summary entries for ns1 and ns2 at GoDaddy .co.cc domains with A records for ONLY ns1 and ns2 Hosted with other nameservers. Have only A records for ns1 and ns2 But these do NOT work (nameserver not registered error): .info domains at GoDaddy with A records for ONLY ns1 and ns2 Hosts with dyndns.org that point to IP of nameservers Also, when I dig any domains hosted at my nameservers using any of the above, I get the correct response. So what's the deal here? Why do the last two cases get "nameserver not registered errors"? Thanks!

  Hello, I'm currently in need to have xxx.one.com load the content of yyy.two.com. That means that when someone will enter xxx.one.com they'll actually see the content of yyy.two.com (URL in the browser won't change and will remain xxx.one.com). The domains are hosted on separate hosting company. yyy.two.com is on a cPanel and xxx.one.com is on an unknown hosting plan, though I can get its details. yyy.two.com have the same IP of www.two.com and this cannot be changed (as the hosting company told me). Any ideas on how do I tackle this issue? Thanks, Roy
