I am trying to access localhost by my ip address. My ip address is/was (It is set to be automatically assigned so it keeps changing).

When I enter http://localhost/ into the browser I get the xampp homepage.

However when I enter into my browser I get the following message:

The server requires a username and password.

User Name:

How do I get the username and password?

To access the server from itself, use http://localhost/ or

To access the server from a separate computer on the same network, use http://192.168.X.X where X.X is your server's local IP address. You can find the sever's local IP address (assuming it's Linux) by running hostname -I.

1 works on this computer but it does not work on other computers. works on any computer in my network but requests username and password... ;( Sorry for taking so long. I hadn't expected answers this quickly. :D – Malte Werschy Dec 5 '10 at 6:29
Problem solved. I can access the computer by using :D Thanks for all the help! :D – Malte Werschy Dec 5 '10 at 7:28
@Malte Werschy: Sorry, I must have missed your reply until now. I've updated my answer with information about local IPs (192.168.X.X) which should hopefully allow you to bypass whatever security policy is denying you access. – Zaz Dec 31 '10 at 19:45

Do you have a Modem/router type device to connect to the internet? It sounds like you are connecting to the configuration interface for this.

Alternatively: On what platform do you use XAMPP? Could you post the output of ipconfig in Windows or sudo ifconfig in Linux/MacOS?

--- Edit

OK, so with the info you gave here, it is now clear what the problem is (and that this belongs on instead of Serverfault).

When you try to connect to your public IP address, you are in fact reaching your router, not your XP box. If you really would want to connect to the XAMPP server with this public IP address, you would need to configure your router to forward port 80 to your XP machine so that it is accessible from the outside (you will find how that is done in the routers documentation). However, this is a terrible idea if you just want to test things and don't need others to access it. Instead, you would either use, which would only work on your XP box, or, which would be accessible from any computer in your home LAN.

Could you edit your original question and tell us why you want to use the IP address instead of http://localhostin the first place?

NB: The info you gave on the router/modem stated that it's firewall is deactivated. This is normally a really bad idea, I would strongly recommend turning it on. How this is done will also be explained in the documentation.

Yes I do have a modem. The ip address of the modem is The data report of the modem is: System Type: SpeedStream 6520 Series DSL Connection Information: UP Router IP Address: WAN IP Address: Firewall: Off Config Part #: 003-a193-G02 Firmware Part #: 004-E752-A64 MAC Address: 00:13:A3:D0:FB:2A Up Time: 0 days, 21 hours, 6 minutes, 36 seconds I use xampp on windows xp. the output of ipconfig is: Windows IP Configuration Ethernet adapter Local Area Connection: Conection-specific DNS Sufix . : domain.invalid Continued in next post. – Malte Werschy Dec 5 '10 at 6:41
What is it with this formatting? Am I doing something wrong? How do I get {enter_key}? Anyway continued report is: IP Address: Subnet Mask: IP Address: fe80::203:dff:fe44:41df%4 Default Gateway: Ethernet adapter Wireless Network Connection: Media State: Media disconnected Tunnel adapter Teredo Tunneling Pseudo-Interface: Connection-specific DNS Sufix: {Continued} – Malte Werschy Dec 5 '10 at 6:49

Malte, I edited my answer with some more infos. Also, it should be possible for you to edit your question to append infos like the above. Doing this in the question instead of a comment makes it easier to format and easier to find. – Sven Dec 5 '10 at 12:14

http://localhost is NOT the same as

The localhost address is 99.999% of the time mapped to the IP address and is totally inaccessible from anywhere except your local machine

What you're finding when you're entering is that your modem/router device owns that IP address, so you're getting the login screen for it.

So i need the password of the modem? – Malte Werschy Dec 5 '10 at 6:58
@Malte - no, you clearly didn't read what I wrote. You don't want to use - you want to use If you're trying to get other people to see your site (you don't mention this in your question), then this is another matter alltgoether. – Mark Henderson Dec 5 '10 at 9:26

It sounds like you are trying to connect to your modem. That means you havent made your router configiration in your modem for your static ip...if you dont have an static ip, you cant make route to port 80 with this ip adress...and this shows, you cant log in to localhost with this ip...use to connect localhost instead of this, if you dont have an static ip and if you havent made config of your router...
