I'm using RasDial (in managed C++) to dial out a VPN connection. The connection doesn't go through, and I was looking at the GUI interface in Windows's connections list. When I look at properties\networking to see the list of components (aka, where you go to set an IP address), I see that neither "Internet Protocol Version 4" or "Internet Protocol Version 6" are checked. What does it even mean for RAS to be trying to connect without IP? How do I make RAS use IPv4?
On the RASENTRY you create to setup the phonebook, set dwfNetProtocols=RASNP_Ip. (in case you want IPv6, just set it =RASNP_Ipv6; of course I only finally figure it out after asking for help)

Briefly question. As the title shows of, Im searching for a possibility to config openWRT so that only one client connection will be allowed over an access point. Further connection trials should be rejected if one client is connected already. Is this possible by configuration only within the openWRT config?
I think you need to set the maxassoc option in the wifi-iface section. Setting it to 1 should do it.
The option is described here: https://openwrt.org/docs/guide-user/network/wifi/basic#common_options1
I know in airports, for example, I've connected to their AP, and it pops up a browser window to log in on my device. Is it possible to do so with NodeMCU in lua, or even with c firmware?
This can accomplished by setting the DNS server for a connecting client [via DHCP] to a sort of DNS proxy. It doesn't need to be a fully featured DNS server, it only needs to be able to either return a static DNS answer for any host name query or forward the request to a real DNS server, to resolve host names as usual.
The static answer effectively hijacks web requests at the DNS level, by forging the DNS answer, causing all host names to resolve to the IP address of a local web server. That local web server ignores any Uri details and serves a login prompt for every request. It must also maintain a list of client MAC addresses that have authenticated.
NodeMCU does have a built-in DHCP server, as part of it's built-in WiFi AP, but running both a web and a DNS proxy in ESP8266's limited memory would be a hell of a trick. I think that two of them working cooperatively, interfaced using the SPI bus might be workable... maybe even three of them, one dedicated to maintaining the list of authenticated MACs, expiring them, etc.
Note that the only part of this I have done on an ESP 8266 is some very simple web server functionality, so it's mostly theory. If you try it I'd be very interested in hearing about it. :-)
You might want to try out CaptiveIntraweb project (https://github.com/reischle/CaptiveIntraweb) which is based on NodeMCU.
There is also thread (http://www.esp8266.com/viewtopic.php?f=32&t=3618) on ESP8266 community forum that discusses the solution details.
I have installed Plastic SCM server in one of my PCs at home (Windows 7 - Home Prem). The server is accessible from the clients residing inside my home network. It is resolved using the home network PC name as the server address / visible name.
However, I would like to be able to have access to the server from outside the home network. Ideally, I would like to use the IP that has been assigned to the PC, by the ISP, where the server resides. I can deal with the intermittent IP address changes. The PC is just a regular, personal use PC (i.e. not configured as a server).
A couple of questions: Is this possible to access Plastic SCM server from outside the home network using the IP address that the ISP assigns to the PC where PSCM-Server resides?
Second, the server config tool automatically displays as the visible name of the PC, the name assigned in the home network. It does not allow me to enter an IP address. If the answer to the first question is yes, how can I enter the desired IP address?
Are there any configurations that must be in place on Windows 7 (Home Premium), perhaps?
Any suggestions would be appreciated.
Plastic SCM servers listens in two ports: a SSL one and an plain TCP one. I'd strongly recommend you to set up an SSL connection if you're going to open up the port on the internet.

In order to configure your PC:
As you pointed you'll need to redirect the traffic from your router to your PC
The "redirection" must go from a public port to the Plastic SCM port (the TCP or the SSL ones)
Your PC should have the firewall configured to allow incoming traffic to the Plastic SCM port
Regarding your question about "the server configuration": no, it just shows you the name, you can't set the IP since it simply takes the IP/name from your server. It wouldn't work otherwise, unless you mean you've a multi-IP machine. Is that the case? Do you have more than one network card in your PC? If that's the case, there's a way to specify where to listen, but let's confirm first your scenario.
I'm making the assumption that you are using Plastic 4.x (I don't know how similar the 3.x version is to this)
The answer to your first question is YES. I frequently connect to my home plastic server from my work machine to view or grab projects/tools that I need.
Your second question is not technically accurate - what you need is the CLIENT tool to access your server IP address - and that IS possible.
To answer your final question - how to do it: start the Client Configuration tool on this "external" PC.
On the third page of the CLIENT configuration tool, it asks for the Plasti SCM server selection - it gives you an entry for the server address, and an entry for the port.
You most likely have set up the username/password access type on the server, but you could also have used Local users - be sure to select the appropriate log-in type you configured your server for on the final page.
Your only other consideration is the Firewall on Win7 (and as pointed out by Pablo, your router config to 'point' to your server machine on the desired ports (8087/8088) need to be forwarded) must allow those ports to be accessed. (I believe 3.x used different ports)
What i want to do is to set xampp so that when i give my ip to someone they can access my site. The reason for me to find something like this is cause i want to embed paypal testing to my site and it is needed to set a URL for the customers to return to my site when they complete their transactions... I run XAMPP 1.7.7 and my modem is a siemens. Also is there any free way to get a url ie blahblahblah.net or something like this?
In order to do this you will need to set up port forwarding on your router to your web server on your machine (you will have to look at your Siemens router documentation on how to do this). You will only be able to do use a custom URL if your router suports dynamic DNS, which most modern routers do. This required because probably the way you access the Internet your IP address can change each time you log in. If this is the case, you can get one free domain for this purpose at DynDNS.
I have a Ruby on Rails application running on localhost:3000. I would like to make it available world-wide, using x.x.x.x:3000 (my IP address).
I'm on Windows XP SP3.
Disable your firewall(s)
Ensure you have port forwarding for your computer enabled in your router (if present)
Thats all! ;)
The key is to run it on the internet facing network adaptor, which might already be doing. You then need to to set up port forwarding on your ADSL or cable modem, if you are behind one (or a similar NAT device). Finally, get a friend to attempt to connect to you.
You might want to use a DNS service to alias your IP address, so people don't have to type it in by hand.
If you specifically need "localhost:3000", then go for #Joe answer, but if you do not care about the URL, you can use https://ngrok.com/.
Simply download it, then run ngrok localhost:3000 in terminal.
You would probably want to ensure that you have a static IP address to start with. You can apply to your ISP for one of these.
You then want to ensure that you have adequate security in place...there are tons of books etc about hardening your server.
If you have a static IP address, you'll need to turn off your firewall and you should be able to reach your machine. (Turning off your firewall isn't really a good idea, but that's a different question.)
If you have a dynamic IP address (you probably do if you're not sure), you need to look into something called "Dynamic DNS", as this will allow our computer to have a constant name, even if the IP address changes. Note that with all the technologies at play these days, your IP address locally is usually not the same one you see publicly. This can be a bit confusing if you're not sure what's going on.
All that being said, most people would opt for some sort of external hosting. This is much better from a security standpoint. Look at heroku for rails hosting. Their free option may be exactly what you need.
If you are running Apache on Windows, there is a button in the Apache tray icon. I can not recall the name but is something like ''go live''. And of course you have to set up the firewall or port forwarding on your router.
You answered your own question. IP addresses are unique over the internet. Just type in the x.x.x.x:3000 and you're there. If you want a human-readable address like yahoo.com, look into dyndns.com or other free domain-name services.
