Cloud9 paid plan - More than one external port? - cloud9-ide

Does cloud9 give access to more than one external port with their paid plan? I know that free plan only has one but i am wondering about the paid one.

EDIT: Workspaces now have 3 external ports, released a few days ago but not yet documented.
They have 8080 (the default), 8081 and 8082. To access them simply append the port number to your preview url (eg. http://projectname-username.c9.io:8081) and it will connect to whatever is running on port 8081.
These ports have some small issues with https which we'll improve over the next few days but http works fine.

socks5 proxy: enable for only certain IPs

I have a webpage and a little game server running on my own machine that is located at my work office.
The problem is that some people can't reach the webpage and game server, because of some network issues. The reasons are not the key, just take it (for almost all my community all things works fine, there just some troubles for a specific group).
So,
I have set up the test Droplet on Digital Ocean, with socks5 proxy installed.
https://github.com/hensly/socks5
And it all worked :) Clients that are restricted to connect directly are just using my proxy server to connect to the webpage or game server.
.
So my questions come up:
How can I limit my proxy to work only with certain IPs? Actually, I need only one IP - the IP of my server-pc, and that's it (the reserved (white) IP and domain name attached to it). Is there a way of such limitation on the proxy side? I just don't want them to use proxy for everything (mostly because there is not an unlimited Bandwidth and it could cost some extra).
Thanks <3
p.s. if you know other, more convenient ways to solve my problem, I'd appreciate it if you share your thoughts.

How can you share the same port between two apps in Windows?

On a Windows machine, I need two apps (specifically, IIS and OpenVPN) to make use of port 443 simultaneously. I know it can be done in Linux, but is there a way to do that in Windows?
Here is what I have tried:
I tried TCP port split software, but it did not work out for me.
I tried using .net port sharing, but that seems limited to WCF apps and will not work in my scenario.
Tried to find ways to separate HTTP traffic from anything else, and send those to OpenVPN (but could not find any good apps for that so far).
In short, how can this be solved? For instance, could we write a WCF application that would forward traffic to OpenVPN and IIS?

Cannot Access XAMPP Web Server From External Network

I currently have 4 websites running off my home desktop PC using XAMPP. They are running on ports 80, 81, 7733, and 25293.
The first three run fine when accessed from an external network, however the last (25293) won't load. (This site can't be reached. ERR_CONNECTION_FAILED)
I am port forwarding all 4 ports the exact same way. Just as soon as I'm not on my local network, the page stops loading.
I attempted to open up the port in my firewall as well however that achieved nothing. What can I do to resolve this?
The error I receive upon visiting the port on an external network:
This might be a common issue because you are using 5 digits port number, you may need port validation.
For example this was known issue for Drupal:
https://www.drupal.org/project/link/issues/182916
Are you running Linux, or Windows server?
Do you have another computer on the same network? If so, can that computer access your webserver? Try, because that must be your first step, then worry about being visible to the outside world.
I just saw this link and this one. Try to see if it solves your problem.

Is it possible to install localhost server in one pc and to access on multiple computers on a same network.?

We are building php web application while i am a designers and my friend is developer we work on different pcs we want to test the file by runnig on localhost on both of our pc how can we reach it. I have gone through some of concepts in internet but didn't get proper info.
Yes. You need to create a firewall rule to allow access through whatever port you are serving on, probably 8080.
Here is how to create an inbound port rule in windows
Then they should be able to access your server by simply using your ip

I know how to set up a local webserver using xampp on windows... I enter my alias and target on the hosts file (c:\windows\system32\drivers\etc\hosts) and then add a respective entry on my apache vhosts config file. This way, assuming that my webserver is listening to port 80, I can for example map example.com to my local webserver.
I've always entered the whole domain name (that is e.g. example.com) in my hosts file and any requests on that name would be directed to localhost.
Now I was wondering if there's a way to only forward example.com on a certain port (for example only example.com:8080) to the local webserver, and leave example.com (on the default port 80) alone, so that it would still go to my live production website.
As far as I understand this might not be possible using only the hosts file (I tried adding the port :8080 to my domain names - didn't seem work ;-) )...
I really don't know much on this topic so any ideas, insights, links, reading material, tools are welcome.
Edit:
Arnout's reply answers the question I've asked above but doesn't solve my actual problem. Rerouting example.com:8080 to localhost:80 does work and if I access example.com it loads up the frontpage of my local version, but all links on that page of course don't know about the port number and therefore point to the production version... The actual solution to my problem seems to be to bite into the sour apple and fix my application (following Rob's suggestion) and remove all hardcoded urls, so that it works on any domain...
Internet Junkbuster (a proxy server) can do this using its forwarding functionality.
Just add a line like
example.com:8080 localhost:80 . .
to sforward.ini, and uncomment the forwardfile line in junkbstr.ini. Now configure your browser to use a proxyserver running at port 8000 of localhost, and you're set.
I'm sure other proxy servers have a similar feature — I just like Junkbuster since it's a simple standalone executable.
You are playing in the area of domain name services (DNS). Technically, with an advanced DNS configuration (which can include remapping ports), what you propose is possible and it is done routinely on the Internet. However, it is unlikely that you would want to go to that much trouble and expense locally.
On the other hand, I suspect that your real issue can be addressed more easily. Why would you want to have "example.com" resolve to your local web server? You can already reference your local web server as "localhost", as "127.0.0.1", and via its assigned machine name "workstation-x".
The only reason that I can think of, and that I have seen, for wanting to reference your local web server with the same host name as your production web server is due to hard-coding the server host name into your links within your application's web pages. If that is the case here, the answer is simple: don't! You should ALWAYS implement your web applications so that they reference everything (other pages, CSS, JS, images, etc.) relative to the deployed server. If you deploy across multiple servers, then your references must be absolute based on configurable server host names. This is easy to do, and there is no reason not to do it.
If this is not the case, then please explain what you are trying to achieve and what motivates you to try.
EDIT: Since you have confirmed my guess that the problem is hard-coded references to the production host name in the web pages, let me simply add that I have ALWAYS, WITHOUT EXCEPTION, found that it is cheaper to fix the real problem than to accumulate workarounds (such as your attempt to remap ports). I have never encountered an author who has argued the opposite.
Fixing the pages should be little harder than a global search & replace, especially with a decent text editor. Even writing a simple script to change the source files would be vastly cheaper and easier than your attempts at a workaround.
Regardless, best wishes to you, and let us know how it turned out.
Can you confirm if 8080 port is listening on webserver? use the command "netstat -na" to see if the port 8080 is listening.
Did you add 8080 port on apache config file as the same as the default 80 port?
Once you add port 8080 on apache config file to make it listen and double check if 8080 port is listening on webserver, then you will be able to access the page using port 8080. like http://mytestwebserver:8080/index.html or something like this....
