I'm trying to connect to wamp from other computer.
I have a tp-link TD-8811. Is there any way to open my localhost from out
also i dont have a static IP.
A quick look at the specs for your TP-link device show that it is capable of DMZ and Virtual Server configurations. Please see here for a Step-by-Step: http://www.tp-link.com/en/article/?faqid=205 I input your model number in the search and came up with this article. I hope this helps.
There are many options for accessing a dynamic IP from outside.
Almost all services that do CNAME aliases for dynamic IPs offer both free and paid services. I never felt the need to pay for a service that i only used occasionally... The paid packages are usually geared to make your life easier.
Look at: no-ip.com -or- dyndns.com -or- google: "connect to dynamic ip address" and take your pick from the results.
After all of this is done, I'd seriously consider setting up (as an absolute minimum) a quick and dirty encrypted channel for your security. Your Router does not support IPsec/VPN, but that doesn't mean that you cannot ssh to your computer (regardless of host/client OS). There are also port-knocking methods to "speak" to your PC's firewall and instruct it to open your desired data port. You'll need to forward a few more ports from your router to get this set up, but if you'll achieve a closed system that you can open and close again on demand.
Apologies for the non-howto style of this answer, I hope it helps.

So I'm trying to deploy a Ghost blog into a Google Cloud vm instance and I can't get it to work. Part of the problem, I think, is that I haven't set up the DNS correctly. I bought farodefe.org via Google Domains and I tried to configure it following this tutorial, and it worked... partially. I used DIG in Ubuntu to try and verify that my DNS configuration. Here are the results:
enter image description here
As seen in the image above, when I do:
dig farodefe.org
and/or
dig www.farodefe.org
I do receive an answer to my query.
But then I do dig http://www.farodefe.org and I receive nothing.
enter image description here
Why is this happening and how can I fix it?
Thanks in advance!
But then I do dig http://www.farodefe.org
But this does not mean anything, or at least certainly not what you think. The DNS has no concept of URLs, only names.
So you are doing here a query for the name http://www.farodefe.org (which is possible in the DNS, but not just for an A record type which is the default one used by dig), which is certainly not what you had in mind.
Part of the problem, I think, is that I haven't set up the DNS correctly.
Don't think, test. If you are not familiar with DNS, use good online troubleshooting tools, like DNSViz. If you see any red things in the output, your DNS configuration needs to be fixed. Alternatively, your DNS provider should be able to help you.
DNS wise, you first need to understand the difference between authoritative and recursive nameservers and service, and hence when doing tests you need to first send your queries to the authoritative nameservers (which is what DNSViz does) and only when that is ok and you still have problems, then you query recursive nameservers as needed.
If you want to understand more, also learn about the OSI/Internet layers, and how HTTP is layered on top of TCP and IP, which are some protocols among others, and how the DNS (a service itself using TCP and UDP) is used to map data, and in a web setting, to map a given hostname (website) to one or more IPv4 or IPv6 addresses, for an HTTP client (like a browser) to be able to initiate its TCP/IP connection.
I have an ASP.NET web application that has been hosted in IIS local Machine.
My Question is :
Is there any free or paid method that allows browsing this web
application from the internet as Host Server ?
Thanks
The easiest way to to publish it directly onto the internet. You do run the risk of attackers then being able to attach your machine, so you will need to brush up on your security skills. It might be worth looking into one of the free hosting options from AWS, Azure or Google Cloud.
To use your local machine as a web server, first, configure it to use a static IP. Its been a while since I've done it on windows, but this looks about right http://www.howtogeek.com/howto/19249/how-to-assign-a-static-ip-address-in-xp-vista-or-windows-7/.
Next you will need to configure port forwarding on your model. You want to send all traffic on port 80 to your machine, using its new fixed IP address. If your using HTTPS as well, configure port 443 to go to your machine. There are too many different modem brands, all of which handle this slightly differently, to consider offering any more help on this. You will need to do some reading up on your particular modem for step-by-step instructions.
If your internet connection is using a fixed IP, then you can stop here.
If not, or if you just want a domain name, then its worth signing up for a dynamic dns service. I use No-ip, its free, it integrates with my modem and I haven't had any problems with it in the last few years. Once this is in place, you will be able to hit your webserver just like a real one. Using something like "http://mypc.no-ip.biz/mydemoapp/
But again, be warned about exposing your machine on the internet. There are nasty people out there who love to hijack other peoples computers.
Update:
This should give you some guidance on port forwarding
http://www.howtogeek.com/66214/how-to-forward-ports-on-your-router/
Try http://www.noip.com I just logged in and it seemed happy. Otherwise, have a click through all the settings in your modem looking for ddns or dynamic DNS. There is usually a drop down of all the providers that it will talk to. And some providers have apps that you run on your PC , which is easier that working with the modem for some. (Or for models that don't support ddns.)
My college has different proxies for accessing Internet like 192.168.0.2/3/4 and also a specific port number.What is the advantage of using this ? I also would like to know what exactly happens there.I also heard that my institution has different ISP connections shared over the same network. What is the role of proxy there?
It will be very easy to know if you understand what proxies do and why they are used generally. Which could be found on a magical website called www.google.com. By using a proxy, you get more control over the network because all request go through there.Your school may want to do stuffs like traffic shaping, content filtering etc. Using the proxy server will make sure all request to the internet are routed there first.
Proxies are good for a few things:
Filtering. By using a proxy, your college can filter out viruses, porn, Facebook or torrent downloads.
Logging. By requiring a username and password, the college can track what you do with your internet time, and can tell you off if you go somewhere you shouldn't or help you be allowing them to do traffic shaping, or other network maintenance.
Line Bonding. For example, if you have two ADSL lines of 5Mb, you can bond those to get a 10Mb line (normally this is done at the gateway stage, and not the proxy, but it is possible to do it at this stage of the network)
Failover. Again, this would normally be done at the gateway/router stage. This detects which lines are active and routes your traffic to those lines.
Network Connectivity. If your college is in-turn part of a bigger academic network, this could allow crossing those network boundaries to get internet access.
Although those are valid possibilities, it's probably just for Filtering...
In the wider internet, proxies are in use for allowing access to blocked content - like giving China access to Google...
I have some servers in my workplace and they are accessible via Intranet, I want to allow people from external network to access the gateway and all resources in that gateway.
Is there any way to do that without any special hardwares???
I tried installing Hamachi LogMEin ( Gateway Network ) but, it is taking too much time to connect using RDP.
I tried Insta Safe, they are charging bit high!
Although this is not programming related, I thought I would provide you with a solution which should help resolve your issue using OpenVPN and a Dynamic IP address.
Please follow this URL
Snippet:
As Chris mentioned, should you need further assistance, please try an alternative website, perhaps the suggested networkengineering would suffice.
I have 50 machines in a LAN and each of these have internet access. Can a program be developed using vc++ which will tell what are all the websites which is being opened by users in each machine?
You can easily accomplish this by writing an application which captures packets outbound on port 80 (and the associated DNS information). The problem is that this application must run on every client computer which you want to trace. The easier method, as stated by others, is to take advantage of your network architecture and tunnel all traffic through a central proxy which can record the same information.
There are many-many enterprise tools suited for just this task in the latter instance.
Route your internet traffic through a centralized proxy and monitor the traffic from proxy say using Fiddler, or something else. In case proxying is not possible, use Fiddler to generate data at known location and then collate it at required intervals.
Install a firewall, if you don't already have one, and use it to log connections.
