I am using an app called SelfControl. It blocks all Internet traffic as not to distract me, but the app allows you to make a whitelist of sites or services that can be accessed. However, although sometimes the IP range is mentioned on an app's website, this is not always correct, and the app is still blocked.
So, using Terminal or any other default program, how do I find the exact stream URL or IP address a particular app is using (for instance Drive or Spotify)?
PS. I considered SuperUser, but as the solution may involve a few lines of code I thought SO was more appropriate.

I am trying to host a website from my house. (It does not have to be very reliable and consistent, hence I'm hosting from my house from a Raspberry Pi).
My website is obviously working fine locally. I tried to configure port forwarding on my router. It did not work. I then realized that my IP address on https://www.whatismyip.com/ and my router IP address is not the same. After reading up I am suspecting that I am behind another router. That would make sense since I'm living in an estate/housing complex and one ISP provides internet to all units. I can't access the next router (probably due to security reasons from my ISP).
My question is, is there any way around this? Would an ISP in general perhaps grant me a port if I ask them?
P.s. I am using phpmyadmin with my website and I am using Java on a cron-job to execute a program every 2 minutes which changes the DB. So I am not sure website hosting on a third party site would be trivial in my case.
it works now. I emailed my ISP to ask about the situation. Without further questions they assigned me a public IP address. I configured port forwarding and it works. Seems like you only get a public IP if you ask for one.
I am writing a django based application with docker where there are 3 projects apps running in different containers. All django applications run at 0.0.0.0:8000.
But when I check the ip address of containers to browser the application in browser, they all run at different ip addresses:
project1 runs at 172.18.0.10:8000 can be accessed at: 172.18.0.10:8000/app1
project2 runs at 172.18.0.9:8000 can be accessed at: 172.18.0.9:8000/app2
project3 runs at 172.18.0.7:8000 can be accessed at: 172.18.0.7:8000/app3
which makes the hyperlinks of my app unusable. How do I run all the containers at one single ip, 'localhost:8000'?
Any suggestions where I am going wrong?
You are wrong in the design, mapping multiple containers to one ip+port is simply impossible. One port on one ip is always one application that listens, no matter if it is container application or not.
Simple prove: And who would then decide to which container to send the request? To all of them? Then who would decide which response is the correct one? That's what are ip addresses and ports for, to be able to send request to specific aplications on specific machines.
I think you should reconsider whatever you are doing, and do a bit more research on networking. There are several online courses on that. (I don't want to discourage you in any way, just aim you the right direction)
Simple solution without redesign you app, is putting in front of your app reverse proxy (e. g. nginx). That's the response to my rhetorical question. Reverse proxy can be a middle man that can decide to which application send the request based on something else then ip/port. Reverse proxy listens on some specific port and then by rules you provide to it (e. g. path based), can proxy the request to specific app/ip/port and proxy the response back.
But reverse proxy in this case is more a hack than proper solution, keep that in mind.
I want to retrieve IP address of my computer (same as I get on http://www.whatsmyip.org/)
I have a win32 project.
This is the code that I am using, as I didnt find any tutorial on this, I could get following info, but not the IP address which I saw for my computer on the whatsmyip.org :(
The IP I got on whatsmyip.org starts with 116.x.x.x
Your code gets adapter addresses, which are local. If you want your Internet address, you need to use the Internet, not your local network. You need to replicate the functionality of asking an external site what IP it sees you connecting from. See here for some suggestions for how to do that.
Retrieving http://icanhazip.com will do it. You can use whatever HTTP library you like.
The IP which assigned to your machine is not necessarily the IP that you see outside of your local network (e.g. in whatsmyip.org).
Your machine is not directly connected to the Internet with a valid and static IP. Maybe you are behind a NAT. So you can not determine your valid IP over Internet by listing your local assigned IPs in many situations.
To findout what IP address you have in Internet, you can do two ways. Ask from someone over Internet (for example, using whatsmyip.org). Or, query your local network recursivly (which is not easy task)
We're building a web service which users will subscribe to, and we were thinking of authenticating users based on their IP address.
I understand that this creates some hassle, eg, if a client's IP changes, but I wanted to know from a security point of view if this was safe? I'm not sure how hard it is to spoof IP addresses, but my thinking is that even if that happened we wouldn't end up sending data back to the attacker.
Any thoughts?
Thanks!
I'd say this would be very risky. Hackers use a number of IP spoofing tools to avoid detection, and there are legitimate anonymity uses. Check out IP onions via the Tor network (used extensively by wikileaks folks, for example) http://www.torproject.org
That said, if your data isn't sensitive AT ALL, like you want to guess their location to show the local weather, you can certainly use IP blocks to roughly locate people. If that kind of thing is all you're after, check out: http://www.hostip.info/dl/index.html
Think about proxies and VPN's.
And what if an user would like to use your site from an other PC?
You might want to use browser fingerprints (together with IP) it's safer, but then they must always use the same browser...
Conclusion: not a good idea.
I created a web app with Django and I have it running on localhost (http://127.0.0.1:8000/), my question is, how can I make it available to the world, using Mac OS X's web sharing or something?
Thanks!
While you start the server specify the public ip or for any ip use 0.0.0.0
Example:
sudo python manage.py runserver 0.0.0.0:80
If you start your application without ip and port its bind only for loopback which is 127.0.0.1 and will not accessible in your network.
First off, I would strongly suggest you not to serve a website from your Mac. It's a really bad idea™. Both Mac OS X web sharing and Django's included http server (which I assume you're using) are intended for testing purposes only, for a number of reasons concerning speed, security et al. which is frankly too long to post here (but I hope that someone will :)
Second, it's already open to the world: anyone can connect to your computer using your IP address instead of the loopback 127.0.0.1 (unless you're NATted). This, again, is quite useful to test it (and have your friends/colleagues/boss) test it temporarily, but again is not fit for production use. Really.
It depends what your real purpose is, what you mean by "available to the world...or something". If you do want it to be permanently accessible from the web, you need to host it on a server (be it shared or dedicated), you won't keep your Mac turned on forever, will you? :)
For hosting Django on shared hosting - I'd recommend webfaction, step-by-step tutorials on setting up Django project can be found in their screencasts and forums (9.50$ per month for basic plan, with two months money-back guarantee, which actually works, tried myself:). More options in Djangofriendly.com
For dedicated server, ask yourself if you favor managing whole server(OS, web server, database server, memcache, firewall, backups...)yourself. If the answer is "yes", check out Linode, Rackspace, or Slicehost or even amazon web services, but bear in mind it's more expensive, it's way more complicated, but that's what gives you the ultimated flexibility. Once you are ready to try - this is one of the best tutorials i've found in net for a given subject.
If all you need is a proof of concept, that "whatever i can access from my web browser, should be accessible from anywhere in the world", ask your ISP if you are given the private IPaddress. If not, hm, better go for options mentioned above :) If you do, then find out what IP it is by visiting whatismyipaddress.com. Then start the web server as Prashanth suggested, and enter the IP address from whatismyip.org in your browser. Get nothing? a)turn off firewall of MacOSx. still nothing? b)connect your Mac directly to ethernet cable your ISP provides, without router in between. Retry entering your ouside IP in the browser. Works? great, go google "Port forwarding ", this will tell you have to configure your router to have the same effect when router is being used. Doesn't? Ask separate question in stackoverflow and provide as much details about what you are doing as you can.
Mac os Web sharing is uselless if the packets aren't routed correctly to reach your computer on a network. I guess all it can do is start apache, and open some ports in a firewall. But if your personal router or ISP wont forward external packets to your computer - you won't get what you want.
Good luck!
