I’d like to know how to configure my DNS to be able to use a wildcard for my domain and an MX record together. Here is what I’ve done:

@   IN SOA dns100.ovh.net. tech.ovh.net. (2012052100 86400 3600 3600000 300)
              IN  NS     ns100.ovh.net. 
              IN  NS     dns100.ovh.net. 
              IN  MX 1   mail.gestixi.com. 
              IN  A      91.121.39.211 
*             IN  CNAME  gestixi.com. 
www           IN  CNAME  gestixi.com. 

The problem is that when I check my DNS, I get this error:

MX records shall not point to an alias defined by a CNAME

Because of this error, it look like I can’t send my from some internet providers.

mail.gestixi.com needs to be an A record, instead of getting caught by the wildcard CNAME.

If it’s on that same server, then just give it an A record:

mail          IN  A      91.121.39.211

I’m not sure how strictly relays actually enforce this part of the standard, since it just causes some extra lookups, but it’s better to be on the compliant side!

I have a wildcard Cert from godaddy that is installed in our network on a 2008 R2 server running IIS. I have several windows servers now using this wildcard cert and importing into IIS was very straight forward.
My Issue is that I now have a windows 2008 R2 server running JBoss as its webserver and i need to import this wildcard cert into this webserver. I am unclear which steps to take next.
Can someone provide help in importing my wildcard cert into my 5.X JBoss server

Well, for one thing, the biggest difference is that JBoss reads the cert from a JKS keystore. So, for your first step you probably need to import your certs into a JKS keystore. See the JBOSS server.xml and there is a config section for the keystore in the SSL connector.

Now that I think about it, you’ll need to import the signed cert into the very same keystore (forming a chain) that you used to generate a CSR from when you initially bought your certificate.

There might be another way to do it but that is my experience.

I have an ASP.NET MVC app which offers wildcard domains to my users to personalize their login urls.

I’d like to host this on Windows Azure. But is it possible to keep the wildcard domains?

I’ve already found a blog article showing how to do this with CNAME aliases, but that does not seem to work with wildcard subdomains.

Is there some other way? Preferably one that does not require a redirection for each and every request to the server?

Also, what about the root domain (mydomain.com)?

Thanks,

Adrian

It seems that, while DNS standard does not explicitly permit CNAME wildcard entries, it does not forbid them either. So there are actually DNS servers that offer wildcard CNAME entries. Aparently BIND does, for instance.

CNAME based php hostingI have an application that lets users get a *.onemobi.net account (ex. bob.onemobi.net). Now what I would like to do is give the user the option of being able to use their own subdomain to point to their page (ex. bob.hisdomain.com => bob.onemobi.net). I have setup the server and bob.onemobi.net works as expected. I have added a CNAME entry for bob.hisdomain.com => g.onemobi.net (A record on my DNS server) but when I visit bob.hisdomain.com I automatically get redirected to www.onemobi.net. The default behaviour when a site does not exist is to show a page saying “Site does not exist” without any redirections.

I can’t seem to be able to figure out what is causing this. I have tried looking around to see what could possibly be causing this but I’m lost as to what to search for. I’m hoping I can get some guidance from this community.

I think you are missing the ServerAlias directive for the bob.hisdomain.com, it should look something like this;

<VirtualHost *:80>ServerName bob.onemobi.net
ServerAlias bob.hisdomain.com
...</VirtualHost>

basically, because apache doesn’t recognise the bob.hisdomain.com as explicitly aliased to some NameVirtualHost it falls through to the default *:80 NameVirtualHost which is presumably www.onemobi.net

We are trying to set up Windows DNS for our nameservers ns1.sitegen.co and ns2.sitegen.co.

Is is possible to catchall domain names using those nameservers in Windows DNS instead of creating individual forward lookup zones for every domain we wish to host in IIS.

Update:

If you’re DNS servers are not authoritative name servers for the domains you host web sites for, you don’t need to worry about DNS.

All you need to do, is configure an A record (aka. Host record) for www.domain.com and point it to the public IP of the web server.

I’m not sure I understand your question. If you are setting up DNS servers for internal use (answering lookups from local machines with internet access), this is what you need

1. Create forwarders on each DNS Server.
2. Check “Disable Recursion” if you want all queries forwarded (instead of root hint lookups).

Now, all queries for domains for which you do NOT have a forward lookup zone OR a conditional forwarder, will be forwarded to the “default” servers configured in step 1

I’m trying to move my development stuff over to a small local Debian based server running ispconfig, and need to basically make it so that *.dev is routed to a specific IP. So for example I went to http://some-site.dev it would go to 192.168.0.150

Is there any way of doing this without a fancy/expensive router?

Thanks

In Windows, I would say ‘modify your hosts file’. It turns out that my answer is exactly the same for Mac. The link will show you how to modify the HOSTS file in OSX, allowing you to resolve specific hostnames (such as http://site-name.dev) on a network where you have no DNS server.

Since my answer was downvoted, I figured I might as well expand on WHY I think this is the best option for you. Here’s a Microsoft article explaining the concept of hosts files (it also touches on the idea that *nix-based systems have the same file) and here’s a great blog post touching on the same thing, with the content focused on Mac’s.

Before DNS was prevalent, the hosts file was the way to go for specific name resolution. Since you do not have a DNS server (and building one can be a PITA, and overkill for what you explained you needed) just use the hosts file.

I am trying to set up a site which uses code cloned from http://usesthis.com/

My site is at http://hackingtheuniversity.net/

You’ll see that each interview post on the site, uses the following URL syntax

http://firstname.lastname.hackingtheuniversity.net

The creator of the original site uses Nginx and has offered the following for how he achieves this syntax

https://gist.github.com/1840543

I’ve set up wildcard DNS and a ServerAlias of *.hackingtheuniversity.net, but I’m struggling to understand (and find examples) how to port the Nginx rules to modrewrite rules and would appreciate some help.

Thank you.

Something like:

RewriteCond %{HTTP_HOST} ^([0-9a-z+.-]+).hackingtheuniversity.net/?$ [NC]
RewriteRule (.*) /interviews/%1.html [L]

should do the trick.

From a directory of dozens of files, is it possible to GET or PUT two files at once using SFTP?

I do not want to use a wildcard because I don’t necessarily know the names of all the files and don’t want to affect other files.

I’m hoping there’s something like:

get javascript.gs,stylesheet.css

From Google searching and looking on various Stackexchanges, it doesn’t look like this is possible.

Does anyone know for sure?

you can do:

sftp user@host << EOF!
get /path/to/file1
get /path/to/file2
EOF!

But personally I prefer to use scp in such cases.

i have a project where i need to use dynamic subdomains for each user account over https, lets say:

https://username.mydomain.com

So as long as i understand i should buy a Wildcard SSL certificate, i was doing that on rapidSSL but before i buy it I read on some forums that it requires a unique IP for each subdomain, that is impossible for me since i will have thousands of thousands of users.

This is true? what should i buy? this will work for me:?

Yes, wildcard SSL certificates are real thing, it will work. See on the apache wiki how to configure it.

We are looking to set up a service where multiple boxes, in different data centers, would allow HTTPS access. We are looking to set to buy a wildcard SSL cert to handle any number of vanity sub domains.

We are primarily looking at goDaddy’s wildcard SSL cert. Has anyone set up anything similar to this? We have looked at Digicert’s offering but we want to look for cheaper options.

We use GoDaddy’s wild card certs for most of our sites. All our sites are hosted by multiple servers. After you install the cert on the server that creates the CSR export the cert to a PFX file and import it to the other server. The clients won’t know the difference.

GoDaddy knows we do this, and they haven’t ever questioned us about it.
