Why doesn't my D-link router allow entering a port range for port forwarding?
Ok... I got it this time. Follow these instructions: Go back to your settings in the DLink. Click on the Advanced tab. On the left of the screen click the Firewall option. You should be able to open a range from there. If you have any difficulty opening them from there or if it doesn't have a place to do it there let me know what it looks like. We'll get it one way or another. Omg that sux..... I'm assuming it wasn't reset or any cables unplugged during the up/down grade. Dang. I'm really sorry man. You can still call Dlink support and see if they *might* be able to help you. I've never heard of a router that gives any kind of interface screen that can't be fixed. Have you tried logging into it through a telnet session? You might have a little more luck with it that way. I'm not sure DLink routers are accessible through any port besides 80, though. To find out go to Start-> Run and type in "cmd". Click ok and in the prompt window type "telnet 192.168.0.1". If you're lucky you can get in. Let me know and I'll start finding some Dlink commands.
What is port 8080 used for?
Right now, your computer has 65535 potential ports to use over the internet. What's a port, right?Think of a port, like a porthole in a ship. It is a window or point of access to a specific place. You can redirect them in a router, take something sent to one port and alter the path to another. POP3 email programs, like Outlook or Thunderbird, send and receive email through specific ports.... 110 and 995 for receiving email, ports 25, 2525, and 443 for sending email, and ports 143 and 993 for connecting to IMAP servers. VNC servers typically accept connections on 5900, while pushing the java client on port 5800.Your web browser works on port 80. Port 8080 is typically used for a personally hosted web server, when the ISP restricts this type of usage for non-commercial customers. If you were going to host your own website from your computer, you would prefer to be able to do so on port 80, since this would mean that anyone connecting to your computer wouldn't have to add a port number to the end of the WWW address you paid for. They could just connect to it, or to your specific IP address, and they'd have the website visible in their browser, while being served from your desktop or laptop.Some ISPs want to avoid people paying for a cheaper home connection, but using it for commercial webservice. So, they restrict access on port 80. To get around this, you can use whatever port you like. You could use port 12345 if you wanted to. Port 8080 is the just the default second choice for a webserver.
What are TCP, UDP, Proxy, port, local host, ip address?
TCP and UDP are simply put two ways of sending data from one place to another. TCP ensures that the data you get is always right, so it does a lot of checks for you. That makes TCP connections a bit slow. UDP tried to make the data reach you as fast as possible. It sometimes makes small mistakes because of being in such a hurry I would suggest that if you are downloading text documents like ebooks etc. use TCP If you are listening to songs, use UDP (you will not even notice the difference of sloppy delivery) Proxy (Server) is a large computer that does the surfing for you. So assume that you want to go to yahoo.com, yahoo will find it very hard to handle all the people who want to see yahoo.com at the same time. A proxy server can then visit it for say 100 people and next time, if you ask for yahoo.com, it can send you the page all by itself (so yahoo is not overloaded) and you think the service is faster. IP address is a way all the computers connected in the internet identify themselves. Each computer is given 1 unique IP address (much like we all have postal addresses). So if you know the IP address of each computer, its easier to reach that computer, rather than meander arounding asking people whether they know where this computer is connected. An IP address looks like 192.168.12.234 Port is like an electric socket at your home. Assume that you hv two TVs at your place, and both are tuned to different channels. So even if the channels knew that they are broadcasting the stuff to the same house (or IP address), they know that eventually it goes to two different sockets (or ports). Your computer has one IP address, but multiple ports. These port are numbers like 80, 3012 etc I am simplifying all these terms for you to understand. I will recommend that you talk to your ISP or a local "computer-expert" to help you identify the exact proxy, IP address, port etc for you. All the best!
How do I access the wamp server (localhost) page of my computer, from my android mobile browser?
Configure ApacheNow Apache needs to know what to do with these IP addresses, so find the httpd.conf file first, mine was here:C:\wamp\bin\apache\Apache2.2.11\conf\httpd.confFind the line:Listen 80and change it to add your IP addresses with the port:Listen 192.168.2.100:80Listen 192.168.2.110:80Further down in this file you need to configure the access to the directories that host your sites, like this:
How can I ping a specific port?
On windows you can use telnet. You can install it by going to Control Panel -> Programs and Features (formerly add/remove programs) -> Turn on windows features -> scroll down to telnet client. click the box. click ok.Now open a command prompt and type :telnet [server name or IP address] [port number]For example:telnet mymailserver.mylocaldomain.com 25will open up a connection on port 25 (SMTP). If it's successful, with SMTP at least, it will give you a message from the SMTP server and you can send commands back and forth, even send mail to people. With other protocols it's a bit spottier. Often you'll just see a black screen with a cursor and if you press something it will return to the command prompt. With HTTP sometimes it will display a web page (the HTML of it, at least). If it definitely doesn't work it will give you an error. It is prone to false positives, however.
What is SSH? Do I access it using FTP and do I need a password to access SSH or does protect my FTP password?
SSH or Secure Shell has nothing to do with FTP. Unless you are running Linux or Mac OS X you will need to download PuTTy which is a SSH client for windows. here is the link and yes you need a password and username. to ssh another machine you would type ssh user@domain.or.ipaddress and press enter You will then be prompted for a password. I am assuming you are trying to access you webhosting server. You will also need to know some *nix commands. Typing dir will not get you a directory. For the directory you would type "ls" if you do a search for Linux or Unix shell commands you can get a full list.
How do you access Localhost (XAMPP) from another computer over the internet?
In computer networking, localhost is a hostname that means this computer. It is used to access the network services that are running on the host via the loopback network interface. Using the loopback interface bypasses any local network interface hardware.The local loopback mechanism may be used to run a network service on a host without requiring a physical network interface, or without making the service accessible from the networks the computer may be connected to. For example, a locally installed website may be accessed from a web browser by the URL http://localhost to display its home page.The name localhost normally resolves to the IPv4 loopback address 127.0.0.1, and to the IPv6 loopback address ::1Basically it is like saying “My House” or “My Computer” and is specific to the individual making the statement. Me saying “my house” talks about a completely different location than my neighbor saying “my house”. And it is not possible for me to say my house and refer to a different house other than mine. Does that make sense?To refer to a different house I need the address, or in the case of computers I need the IP address that the internet sees the computer to be located at. And there we start to get into how your computer is connected to the internet. Many computers are not directly connected to the internet but share an IP address of the local modem/router that they connect through. How you would connect to the computer is going to depend on are you connecting from another computer that is behind the router or are you connecting from the internet. And I am going to leave that discussion to a time that the question is specifically asked.
How can I make my tomcat local server public?
Hi! How can I make my tomcat local server public? So that other people can run my web-application I don't need domain name or smth like this, I just need to make a person run my application to check whether it works correctly. Is this possible? I installed "No Ip" to get a full-time address to access my PC (because i have dynamical IP..) also i opened the 8081 port in firewall.. When i run it like http://localhost:8081/application It works well.. But when i try to run it as http://My_Address:8081/application It doesn't connect. What else I should do? Are there any easy ways to make people run web-application on my local server? I thought it should be easy with Tomcat... My knowledges in networks are very poor yet. Hope u can help me Thx a lot :)
How do I map a domain name to a node.js web application running on windows server port 3000?
Your question made me curious to see if this could be done by editing the host file - and yes it totally can! While port numbers aren’t normally supported by the host file, you can take advantage of the windows functionality netsh.Example from Stack Overflow illustrating this:Overviewexample.app:80 | <--Link by Hosts File +--> 127.65.43.21:80 | <--Link by netsh Utility +--> localhost:8081ActionsStarted my server on localhost:8081Added my "local DNS" in the hosts file as a new line 127.65.43.21 example.app Any free address in the network 127.0.0.0/8 can be used. Note: I am assuming 127.65.43.21:80 is not occupied by another service. You can check with netstat -a -n -p TCP | grep "LISTENING"added the following network configuration with netsh command utility netsh interface portproxy add v4tov4 listenport=80 listenaddress=127.65.43.21 connectport=8081 connectaddress=127.0.0.1I can now access the server at http://example.appNotes:- These commands/file modifications need to be executed with Admin rights- netsh portproxy needs ipv6 libraries even only to use v4tov4, typically they will also be included by default, otherwise install them using the following command: netsh interface ipv6 installYou can see the entry you have added with the command:netsh interface portproxy show v4tov4You can remove the entry with the following command:netsh interface portproxy delete v4tov4 listenport=80 listenaddress=127.65.43.21Links to Resources:Using NetshNetsh commands for Interface IPNetsh commands for Interface PortproxyWindows Port Forwarding Example
