to be honest, Im not experienced in networking and I need your help. What's the problem?
I have a domain, which should pointing to IP Address, where is the application (orangescrum) running. This was set by our IT Department.
Firstly, Im a little bit confused, because when I ping this domain, I expect to get the IP address of my centos machine, but the IP Address is different. (centos machine has a private IP, I receive another public IP address).
Thats the first issue, which I dont understand.
The second problem is, that when I open the domain in browser, I get the application, but without some images, javascripts, which should be included in application folder. I think, that the database doesnt work as well (I cant log in to the application).
Application worked very well on my localhost, but as I pointing the domain to this ip address, there are a lot of think, which are not working.
I know, that I didnt explain the issue very well, so feel free, if you need to specify anything about the set up.
Thank you so much in advance for any idea.
You need to route your machine if you want to access as public static IP or Private add to your DHCP web router if you got admin access http://192.168.1.1 or http://192.168.1.254 debian of ISP try too.
sudo ifconfig
In a intranet context you can add to your hosts the ip_lan domain.lan.com
on linux : sudo nano /etc/hosts
on windows : cmd as admin
notepad c:\\windows\System32\drivers\etc\hosts
the first may be solve the second problem, if no, just look on the code source looking for your "localhost" domain writed on the code source to changing/adding as a variable global and only one reference domain, simple for editing in the future.

So I run a semi-private website for myself, locally hosted on my network, and port forwarded to the web. I changed from using one computer to another to host it, and whilst my public IP address correctly points to the new computer, the subdomain I'm using to access it doesn't.
From what I've gathered so far, this is only an issue on the old host computer, when I dig the subdomain, I get a reply from that localhost saying the subdomain points to localhost, but everywhere else the new subdomain points to the public IP. If I dig and ask even my router for the correct IP it points to the public one.
I've tried to flush the dns cache, but that didnt change anything.
I'm running Ubuntu Linux, and really confused.
I found it, it was set in my /etc/hosts file, I must've done that and forgotten about it
I am aware that this question does not really pertain to programming but I have now resorted to using you guys, so please help!
So I believe my problem resides in the DNS region, I am hosting a web server on my raspberry pi and am trying to use it to host my website(codetendency.com), I bought my domain from godaddy.com and I pointed "#" to my raspberry pi's IP address and when I try to access my website at home through my home network it works out, but when I tried to access it from my phone on my mobile data, the server doesn't respond.
I would greatly appreciate any help you guys could give me.
The name codetendency.com resolves to the IP address 192.168.0.201. That address is part of the private address space (see RFC 1918), which is not routed on the public Internet. If you want your server to be visible on the public Internet, you must provide a real IP address.
Perhaps someone has some help? I am running dnsmasq on Ubuntu 12.04 LTS. This server's address is 192.168.15.3. My gateway's DNS is 192.168.1.254, that takes me out to the Internet. I also have a special-purpose DNS at 192.168.15.2. So I wanted to give those 3 name servers to DHCP clients. This is my dnsmasq.conf server= section:
server=/localnet/192.168.15.3
server=/localnet/192.168.15.2
server=/15.168.192.in-addr.arpa/192.168.1.254
However, when I look at the DHCP allocation on a client, I see only 192.168.15.3 as the sole DNS server. Clients cannot access the Internet (the NIC on .3 is configured correctly and can access the Internet from its console login).
Granted, the first server= line is probably not necessary, but I added it thinking it may help, didn't.
What am I doing wrong? Thanks for your help!
OK, after MUCH experimentation, I found I had to push the option manually. In the dnsmasq.conf file, I added the following line:
dhcp-option=6,
like so:
dhcp-option=6,192.168.15.3,192.168.15.2,192.168.1.254
This served the correct list of name servers to DHCP clients.
The server lines are configuration for dnsmasq's own DNS server, about where it should forward DNS requersts that it receives in order to be able to resolve (and cache) them.
Only the dhcp-options are part of the DHCP configuration that get passed to DHCP clients - so, the accepted anser is correct, but I wanted to share why.
Hi I have a Huawei ADSL modem with a dynamic IP. I set up a dynamic dns with freedns and I can easily access my Virtual host on apache from outside my private network, from internet.
So trying to access it from a local network I get a modems login page.
I have the rule in my modems NAT to connect port 80 to my server but it seems it doesnt work from internal net.
My server hosting the virtual host is 192.168.0.1 , the modem has the 192.168.0.254 address.
I tried to put my external domain name into the /etc/hosts file, but if I do that then asterisk server gets confused.
What could be the cause of the problem ? And what would be the best solution to this problem ?
Should I set up a caching DNS on the private side of the net ?
Hugger is half right... Its because your router is blocking loopbacks. The easiest way around this is to edit the hosts file (See the Wiki page) on the computer that is behind the network to see the local IP of the computer as the virtual host your going for. For example if your server is on 192.168.0.1 and the virtual hostname is www.imrad.com then insert
192.168.0.1 www.imrad.com
into your hosts file. If your computer leaves the local network (like a laptop you take to work) and joins a network not behind your router you need to comment out the line in the hosts file.
well actually to access that you must find the local ip address of the server by going into command line/prompt and typing ipconfig /all then you will find ipv4 address. Take note of that.
Go to another computer and your that ip and it will show.
The reason that was happening is because the router/modem knows you are in its network so it will think you ar trying to go top the login page of it. That happens to me too.
I've been developing locally on a little ubuntu netbook with xampp for about 7 months. Two weeks ago I got a computer I'd like to use as a server. I've installed the latest Ubuntu distribution and xampp, moved all my files over, and forwarded port 80. I've also got a domain name from dyndns.com which is being updated by a client which runs in my router (a Netgear WGR6154 v8).
Now, when I try to access my server by typing in the address I got from dyndns.com the browser loads until it timesout. I can access everything locally using localhost as the address so I believe xampp is running, just unable to connect with the internet.
In order to be able to view my files over the internet what should I do next?
Thanks to all in advance...

You have a combination of issues here, and that is something of a problem. Each issue is complex in an of itself. Here is what I would recommend to get you going for certain.
First verify that you can surf the web from your server. This will confirm that you have a working ethernet interface.
Step 1 make sure that XAMPP, and your files are viewable from your home network. I assume you are using something like 192.168.1.X for your network and perhaps your server is 192.168.1.10
Go to another computer in your house and type http://192.168.1.10/ and see if you can see your files. If you can then you know that the server is properly configured and XAMPP is working.
Then add an entry to your hosts file to resolve yourdnsrecord.com (or whatever your dyndns record is) to your private ip address. Then when you type yourdnsrecord.com into a browser from that computer you should still get your files. This will rule out your server being improperly configured to listen for that domain name.
Next you need to test to see if there is a firewall problem. To simplify this, first remove your home router from the equation. Instead, place your new server directly onto your internet connection. (assuming you can). This way, you do not need to have NAT or firewalls properly configured. Your dyndns name should map to a public IP and your server should then have that IP and be connected directly to the Internet. If you have your server directly connected, and the command ifconfig from the root prompt returns the same public IP address that your dynamic dns record is point to, then it should work.
It will make your life easier if you have an iphone or some other way to test how your network is seen from the Internet.
If your public IP as shown by ifconfig is different than the IP record in your dyndns account, then your dynamic dns update script is broken. manually set the IP, and see if things work.
It is very possible that this will not work. Some ISPs firewall port 80 preventing their subscribers from hosting servers. Once you have your server directly connected to the internet you can test this (even if your dns is not working) by using the public IP address. As root, type ifconfig from the command prompt to get your public ip address. Then type the command tcpdump -i eth? port 80 from the root prompt. eth? needs to be the same interface that you saw had a public IP address from the ifconfig command. usually this is eth0 but it might be wire0 or something like that.
This command will show you all traffic coming on port 80 to your server.
From an iphone (or whatever second Internet connection you have) browse to the IP address that you got from your ifconfig command. If you see something on your server (and it is directly connected to your ISP) then your ISP is not firewalling you.
If you can get to your server, when it is directly connected to the Internet, either by IP address or by DynDNS address, then your ISP is OK and it is time to debug your firewall.
Two things need to work for your firewall to be configured NAT, where the public address that your router gets from your ISP is converted into your private network and a firewall rule which permits that traffic. If you get this far, then you know your firewall is the problem and then it is just a matter of getting its configuration correct. There are far to many home routers to document here, but you usually can find how-to instructions for your router for this task from the manufacturers website (usually it is part of the manual)
If you follow these instructions exactly you will get your system working. Make comments on the process and I will be happy to modify this to make it clearer.
HTH,

You should make sure your xampp is not listening to only the localhost.
to do so edit your apache configuration file and check and search for Listen directive
you should be able to know also by analysing the output of netstat -a.
After that make sure your router is forwarding properly, using tcpdump would help.
drop me a comment if you need more help.
