how to access localhost using ip of pc? - apache

I am trying to run my local host app using my system ip but its not working.
http://localhost/bootstrap/bs1.html - working
http://xxx.xxx.xx.xx/bootstrap/bs1.html -not working
using ipconfig command I got the ipv4 .
how to make it?

As you are using IPConfig, I assume you are using Windows as well.
Open notepad as administrator, navigate to Windows\System32\drivers\etc and open hosts file (Windows 10).
Uncomment or add a new line with following entry:
127.0.0.1 localhost
Then flush your DNS cache in your terminal with command:
ipconfig /flushdns
You might experience browser caching at this point, close and reopen browser if needed.
This is for localhost only, so host machine and guest machines (if any).
If you want to give an access to your server externally, like for anyone over the internet, this is much more complicated tasks and would require port forwarding.
But there is simpler solution and workaround for doing it and I recommend using Ngrok which is super simple CLI tool that will do work for you.
It's a secure solution as you are not exposing anything on your computer directly but instead it uses a secure tunnel to provide your localhost on *.ngrok.com/* link.

Accessing localhost (xampp) from another computer

First, I already searched stack overflow and followed the suggestions in previous answers, such as How do I connect to this localhost from another computer on the same network?
I have created a PHP/MySQL application for a client. The want to host it locally on that server.
The machine in question is running an application written in another langauge (I'm not sure which one) and running Tomcat on port 8080.
They also do not have separate staging/production environments, so this is not ideal.
Their other web application needs to remain running while I also port over the new app. I installed XAAMP onto their system and got the app running locally using Apache HTTP. However, they want other computers both within and outside their networks to be able to connect to the Windows server as well. They are already doing this for the previously created app that is running on Tomcat.
Ports 80 and 8080 are already being used, so the firewall was updated to allow my application to run on port 8086.
I used ipconfig to the find the local IPv, and then tried updating the http.conf and vhost file and am listening to the IP on port 8086. However, going to the IP/foldername doesn't resolve on another computer in the network. As a test, I also just typed in the IP of the windows machine, and it never resolves.
I generally don't implement of windows; until now, all of my production applications have run on some flavor of unix. Their other application is live and I don't want to disturb it. They access it by going to {servername}:8080. I tried server:8086 to see if my app could be accessed that way, but it can't.
I confirmed that localhost/foldername resolves.
Here are the exact steps that I have taken. I tried two different solutions.
Solution 1, using How do I connect to this localhost from another computer on the same network? as a guide:
Make sure firewall allows port 8086 access
I modified the C:\xampp\apache\conf\extra\httpd-vhosts.conf file to include a virtual host for the application:
DocumentRoot "C:/xampp/htdocs/{foldername}"
ServerName dispatchserver
Went to the Windows host file located at \Windows\system32\drivers\etc\hosts and added the following:
192.xxx.x.xx dispatchserver
From a computer outside the network, tried to go to the following URLs (non resolved):
http://192.xxx.x.xx
http://192.xxx.x.xx:8086/
http://192.xxx.x.xx/foldername
http://dispatchserver
http://dispatchserver/foldername
Since they didn't work, I tried a solution using this older stack overflow answer: Accessing localhost (xampp) from another computer over LAN network - how to?
Made sure firewall allows port 8086 access
XAMPP control panel > Config > Service and Port Settings > Apache > Changed main port to 8086.
XAMPP control panel > Apache > Config > http.conf
Searched for "Listen 80" and replaced with Listen 8086
Right above that, added Listen 192.xxx.x.xx:8086 (I used the IPv4, but don't want to include full address for security reasons). I added this line with hashtag at first (#192.xxx.x.xx:8086) and then without hastag after that didn't work (192.xxx.x.xx:8086).
Searched for and set this up as the directory statement:
AllowOverride All
Require all granted
Restart Apache
What steps can I take to allow the new webapplication I installed via XAMPP to be accessible to other computers?
In that case it's a little different if you want to web enable this. You need to set up your router to port forward to your server (app)so that the other network can reach it from the internet. Your router blocks incoming requests by default so a port forwarding rule using the port you mentioned will work. You should also put your server computer (the one with the app) on a static ip address to make things easier. Then for the user to see your app you need to give them the ip address of your internet connection (seen via sites like ipchicken.com) and the port number in the url.
Normally you just need to open the ports in the windows firewall on both computers (inbound and outbound) for the ports your application is using and then connect to the other machine via ip address and port number if they are on the same network.

How can I open a web browser on a server that I can connect to through ssh?

I'm in a computer science program at my university (Ryerson) and I'm learning perl programming.
The way we're learning is by hosting perl scripts on our university's server and doing stuff with them.
I'm away from the university and the university's server is very strict about which IP's can use the www2 subdomain (which is the subdomain that runs perl scripts). And the IP I'm working from gets me the error:
Forbidden
You don't have permission to access /~w3dixon/cgi-bin/lab4.cgi on this server.
Apache/2.2.22 (Debian) Server at www2.scs.ryerson.ca Port 80
Here's the link, if you want to try to access the script yourself.
So I'm being blocked. Normally I'd contact the sys admin and get them to unblock me, but a working perl script is due tonight. (I also tried using a VPN, it was blocked as well).
My solution was to SSH with terminal on my mac and/or Putty on my PC into Ryerson's server and use the unix command 'lynx' to run my scripts (since they aren't blocking their own IPs).
I was having some success, until I tried to use the perl get method from an html form (I copy pasted a script from https://www.tutorialspoint.com/perl/perl_cgi.htm just to get started, to see if syntactically correct code would work properly with my lynx strategy).
So when I was working on my script using a terminal at the university (with google chrome), my scripts worked fine.
Ryerson (my university), doesn't have a remote access program set up (other than ssh), but is there a way to access my webpage through their servers on a GUI browser installed on my machine?
An SSH tunnel is most likely the most feasible and easiest way to do what you want. Set up the tunnel like this:
ssh -L8080:www2.scs.ryerson.ca:80 username#www2.scs.ryerson.ca
If the www2 server is not the host you SSH to, simply replace the second instance of it in the command with the SSH server.
I use port 8080 here, as that alleviates you from needing root privileges.
Now, on your local workstation, in your browser, browse to:
http://localhost:8080

Start ipython cluster using ssh on windows machine

I have a problem setting up a ipython cluster on a Windows server and connecting to this ipcluster using a ssh connection. I tried following the tutorial on https://ipython.org/ipython/doc/dev/parallel/parallel_process.html#ssh, but I have problems to understand what the options mean exactly and what parameters are to use exactly...
Could anyone help a total noob to set up an ipcluster? (Let's say the remote machine has ip 192.168.0.1 and the local machine has 192.168.0.2)
If you scroll roughly to the middle of the page https://ipython.org/ipython-doc/dev/parallel/parallel_process.html#ssh you will find this:
Current limitations of the SSH mode of ipcluster are:
Untested and unsupported on Windows. Would require a working ssh on Windows. Also, we are using shell scripts to setup and execute
commands on remote hosts.
That means, there is no easy way to build an ipcluster with ssh connection on windows (if it works at all).
Do you really need to connect the machines with an ssh connection? I guess it's possible with a ssh client on each windows machine, but if you are in a trusted local network you can also decide not to use the loopback interface and just expose the ports...
Sure you can start controller and engine separately! For further examples about ports (if you have problems with firewalls) see also How to setup ssh tunnel for ipython cluster (ipcluster)

Hosting site using xampp server from local network without port-forwarding

I want to make my site available world wide. Im using xampp server for hosting. I have no access to any kind of servers and modems. Situation is shown below:
My site server has local ip assigned by wifi router and it runs Windows 8.
Remember I have no access on any kind of servers and modems so port port-forwarding is impossible (out of my scope).
Its actually difficult, but not impossible.
One way, I would approach this is:
I would host a page on internet.
Then take request and store it in database.
One of my program will always be running from my computer.
Then check for request and curl the request to localhost. For this you may use Node.js (taking data from database using GET method and curl it to localhost).
This is the best I could think of. And I am working on it, when the code is ready I'll make it open source and notify you :)
But still, it's difficult, as you need to put user's request to sleep for 2 seconds and then transferring it.
Its slow, but may work out for you.
Disadvantages:
Program will be very slow and memory usage will be more.
Breaking may happen many times.
High bandwidth wastage
If not encrypted, MIM (Men in Middle) may possible.
Advantages:
Indirect method of hosting
Need not to worry about your code being lost.
I am looking forward for a better alternative and I would like to keep this question for bounty once again.
If you cannot open the necessary ports within your LAN you will require access to an external server. However, the external server does not need to host any code, e.g.
Create a Linux based ec2 instance using Amazon's free tier.
Install a package to redirect remote to local ports:
a. using socat:
Install socat using your distributions package manager
Connect via SSH: ssh -N -R 42500:127.0.0.1:80 -o ServerAliveInterval=60 ubuntu#xxx.xxx.xxx.xxx -N -R 8080:localhost:80 "socat TCP-LISTEN:8080,fork TCP:127.0.0.1:42500"
b. using a webserver and reverse proxy:
Install apache or nginx and any required reverse proxy modules and configure your VirtualHost to proxy requests to a local port, e.g. :8080 -> 127.0.0.1:42500
Connect via SSH: ssh -N -R 42500:127.0.0.1:80 -o ServerAliveInterval=60 ubuntu#xxx.xxx.xxx.xxx
Your machine is now reachable via the ec2 instance http://xxx.xxx.xxx.xxx:8080/.
I occasionally use this technique when debugging web service callbacks.
Update 17-02-2014
If you are a Windows user you will need to install a third-party tool to support ssh. Options include:
cygwin
git bash
PuTTY
PuTTY is the easiest choice if you are not familiar with *nix tools. To configure remote port forwarding in PuTTY expand the following setting: Connection -> SSH -> Tunnels. Given the previously described scenario, populate Source port as 42500, Desination as 127.0.0.1:80 and tick the Remote option. (You may also need to add the path to a PuTTY compatible private key in the Connection -> SSH -> Auth tab depending on your server configuration.
To test you have successfully forwarded a port, execute the command netstat -lnt on your server. You will see output similar to:
tcp 0 0 127.0.0.1:42500 0.0.0.0:* LISTEN
Finally you can test with curl http://127.0.0.1:42500. You will see the output of your own machines web root running on port 80.
if you don't have a public IP address and cannot use port forwarding it is impossible to host the site
As people have said you need a public IP address. However, even if you did you should not use xampp as a public server, as it is designed for development and therefore has some security settings disabled.
I would recommend buying some shared web hosting, and uploading it to that. (you can get cheap hosting if you google 'shared web hosting', plus free .tk domains are avaliable: http://www.dot.tk/)
Do your company has any vpn network?
If it does and you have access to the vpn network, you can include your server to the vpn network and your guest will only need to login to your company vpn network then access your site like in a local network without using port forwarding. And since your data is very confidential, I assume that using vpn will also help to increase the security of your data.
Please correct me if I'm wrong.
Thank You.
What you are asking is not possible without port forwarding.
Lets break it into steps.
To host your site locally you will need a IP that is static so that
users can access it specifically.
You will need a domain so that it can be converted into user friendly name.
A 24x7 Internet Connection is must! You added a Wifi Router in your Diagram and most of today's router are capable of port forwarding.
What i will do in your scenario is:
Instead of using XAMP, i will install WAMP because i am more familiar with it and easy to configure.(totally personal preference)
Then i would set my server "ONLINE".(Google how to set WAMP server online)
Forward port "80" from router settings to my local computer ip address.(mostly it is tagged as "Virtual Server","Firewall","Port Forwarding",etc vary router to router in settings)
Suppose you have a local ip "192.168.1.3" and global/router IP "254.232.123.232" then you would redirect all the HTTP request done towards router to your local IP.
[[[[254.232.123.232]]]] --+ :80 +-- --------->192.168.1.3
That is good for now, but then you will need to tackle dynamic IP problem of router. But don't worry, thanks to some free sites that will be easy!
Go to no-ip.org -> Setup Account -> and create a entry, just a subdomain for now to test whether everything is working fine.(subdomain like mysite.no-ip.org, later purchase a real Domain)
Input your IP address there(Router IP) and download its application which will automatically update their server if your local IP changes.
Wait for some minutes and Voila! Your site is live.

How to access Solr from an external IP address?

I have Solr running on my server on localhost in the Jetty container.
This seems like an obvious question, but how do I access the web interface from outside the server itself, like from an external IP address? Obviously, authentication will be important as part of any solution.
I am also running Apache2 on the server, if that is a good solution. I'm surprised I can't find anything about this.
I finally stumbled upon an answer to this. I don't really need persistent access to the Solr admin panel, so I can easily access it using local port forwarding in SSH.
All I had to do was run the following from a terminal on my local machine:
ssh -L 8983:localhost:8983 mlissner#IP-OF-SERVER-RUNNING-SOLR -N
And then open my browser to http://localhost:8983/solr/
Much easier than setting up an Apache config, doing proxies, and whatever else.
It depends on your Jetty ContextPath. For example:
....
WebAppContext explorerWebapp = new WebAppContext();
explorerWebapp.setContextPath("/solr");
....
and then just navigate to your index:
http://localhost:PORT/solr/
