I uploaded a cakephp based application on new server. But, dns is not defined for that IP. When I try open website by IP address directly it shows Error 404. Can anyone please suggest me that how can I open website on browser?
Thanks
Most likely the webserver isn't configured to accept connections using the direct IP. If you're using a apache webserver, you should most likely change the virtual host. More information here: http://httpd.apache.org/docs/2.2/vhosts/
Nginx has a similar system which is explained here: http://httpd.apache.org/docs/2.2/vhosts/
Most web servers have some similar system. This makes it possible to host multiple websites with several DNS on one physical computer. If you can't access the configuration files yourself, you should contact your host.

I encountered a very strange issue I've seen more often but could workaround. A VPS with Windows Server 2012 on it and IIS installed is unable to access its own webpages by its public IP.
When I open up Internet Explorer on the VPS and goto localhost, I see the default IIS page. Whenever I try the public IP, it times out.
If I access the same IP from another PC, I can also see the IIS page.
I've tried pinging to my public IP from the VPS, this works. I then tried to disable my firewall all to no avail.
Has someone encountered this before? And more importantly: Did you manage to fix it and if so, how?
Most likely then this is a NAT issue caused by how the NAT gateway/router is configured your connections go via. I'd recommend talking to your host and confirming whether this is the reason and if they are willing to do anything to resolve it. That might be difficult if it is a limitation of the router or done for security reasons that they are unwilling to change.
Running some Wireshark traces should be able to confirm what is happening.
You may be able to resolve it your self with Split DNS and the use of a domain name rather than direct to an IP address. Why do you need to use the IP specifically?

I'm building a Node app and need to put it online so my team can access it. We are concerned about the content of the app leaking and need some security.
Is a VPN the best way? Could I set one up easily on Digital Ocean or elsewhere? I have only set up a VPN for tunnelling before, and don't have a local computer or server that is always on.
I first thought about putting it on a randomly generated subdomain on my regular domain, or controlling it with .htaccess and password, but I'm not sure if this is doable with Node.
EDIT: what about just setting up with pptp and then editing the hosts file to point my-temporary-domain.com to localhost?
This problem is relevant because you don't have a local area network that your team all has access to. The way I've solved this in the past is to set up your application listening on the 127.0.0.1 on a server that is accessible to the internet. Allow your team to have SSH access, and set it up so they forward localhost and port 80 on their local machine to whatever port your application is listening on. You can do this with openssh and putty.
I have a slight problem bit of the back story. recently ive been trying to test out univention which is a linux distribution with the goal of being able to replace Microsoft active directory.
I tested it locally and all went reasonably well after a few minor issues i then decided to test it remotely as the company wants to allow remote users to access this so i used myhyve.com to host it and its now been setup successfully and works reasonably well.
however
my main problem is DNS based as when trying to connect to the domain the only way windows will recognize it is by editing the network adapter and setting ip v4 dns server address to the ip address of the server hosting the univention active directory replacement. although this does allow every thing to work its not ideal and dns look up on the internet are considerably longer. i was wondering if any one had any ideas or have done something similar and encountered this problems before and know a work around. i want to avoid setting up a vpn if possible.
after initially registering the computer on the domain i am able to remove the dns server address and just use a couple of amendments to the HOST file to keep it running but this still leads to having issues connecting to the domain controller sometimes and is not ideal. any ideas and suggestions would be greatly received.

For the HOST entries, the most likely issue is, that there are several service records a computer in the domain needs. I'm not sure, whether these can be provided via the HOST file or not but you'll definitely have authentication issues if they are missing. To see the records your domain is using issue the following commands on the UCS system.
/usr/share/univention-samba4/scripts/check_essential_samba4_dns_records.sh
For the slow resolution of the DNS records there are several points where you could start looking. My first test would be whether or not you are using a forwarder for the web DNS requests and whether or not the forwarder is having a decent speed. To check if you are using one, type
ucr search dns/forwarder
If you get a valid IP for either of the UCR Variables, dns/forwarder1, dns/forwarder2 or dns/forwarder3, you are forwarding your DNS requests to a different Server. If all of them are empty or not valid IPs then your server is doing the resolution itself.
Not using a forwarder is often slow, as the DNS servers caching is optimized for the AD operations, like the round robin load balancing. Likewise a number of ISPs require you to use a forwarder to minimize the DNS traffic. You can simply define a forwarder using ucr, I use Google on IPv4 for the example
ucr set dns/forwarder1='8.8.8.8'
The other scenario might be a slow forwarder. To check it try to query the forwarder directly using the following command
dig univention.com #(ucr get dns/forwarder1)
If it takes long, then there is nothing the UCS server can do, you'll simply have to choose a different forwarder from the ucr command above.
If neither of the above helps, the next step would be to check whether there are error messages for the named daemon in the syslog file. Normally these come when you are trying to manually remove software or if the firewall configuration got changed.

I have developed an intranet site using nodeJS and it is running successfully on one of the Windows servers in our office and am now ready to deploy.
At the moment the only route to access is ip:port (192.168.1.88:8888 for example)
I would like for the local users on the network to just type 'intranet' into their browsers and be forwarded to this location. I have tried modifying the system32\drivers\etc\hosts file (with 127.0.0.1 intranet), but it 404'd, telling me that index was not found, so maybe it's trying to serve the application statically with a different web server (IIS is installed on the machine, although it's not running?)
Is there any way to achieve this "shortcut" at network level? It must also work for external visitors to the site so I've ruled out any local solutions.
I am aware that this information already exists online, however I find it is above my knowledge level as a humble javascript developer and seems to strafe into network administration territory. I wonder if anybody could provide a lay mans write up.
I currently have one .local address (Bonjour) pointing to my mac in my intranet, mbp.local, configured in system preferences with the computer name. I use this to send my boss links to demos on my local server (he sits in a chair behind me : >).
I'd like to be able to create new .local addresses to send different demos to my boss (demo1.local, demo2.local, etc) so that I can switch to different working copies to do other work while the demos are still live.
I'd know how to setup Apache to route these requests to the right places, but am unsure if it's possible to make new addresses that point to my mac (I think this has to do with multicasting?).
I have a dynamic IP in my intranet but would be able to setup a static IP if required.
Are you talking about web site demos? I'm not sure I understand the problem. If they're web sites, I'm sure you already know you can simply use a single address with different urls, eg, http://mbp.local/demo1, http://mbp.local/demo2, etc. If it is something else entirely, you can use the Mac's local host file to point multiple fqdns to a single IP address on your local network, but it would be best to have a static IP. Alternatively, you could edit your DNS or WINS server to do the address translation.
I haven't done this myself, but I wonder if you could use what's documented here to start. The difference would be that you'll send your boss links to http://demo1.mbp.local and so on.
I found more about this on this thread on SuperUser.
