I want to find out a person's ip address who is abusing me on facebook. Whenever I log into facebook he shows up in the chat and threatens me. I am kinda hacker but how can I find his ip address in chat using wireshark or something. He is really starting to piss me off. Please HELP.
Wireshark is a fantastic tool but will only be able to monitor network traffic passing through your own network - in this instance, you would be able to monitor your own side of the Facebook Messenger conversation.
There is no direct TCP/IP connection from this person's computer to your computer involved. Both they and you connect to Facebook's web servers and messages are sent and received using HTTP protocol and AJAX.
Most communication services operate in this way these days, partly to protect the privacy of its users, partly for improved performance and reliability, and partly for regulatory compliance. Possible solutions normally include:
Reporting abuse to the service provider and in most cases they will be pleased to investigate it for you;
Blocking the person from contacting you in future using the tools built-in to the service;
Reporting abuse to your local Police, who can legally obtain the IP address and login history from Facebook. They will not pass this information onto you for retribution but if sufficient evidence is available the person bothering you could be arrested and charged for harassment, malicious communications, defamation and/or breach of peace, depending on the local laws where you/they live.

I want to make links for people to email me in github pages but I don't want them to know my actual email. I noticed that username#github.com may be a valid email address. But when I tried emailing that address, I got this:
How do I modify the organisational settings to allow users to email me in Github. If not possible, how do I set up an email for my github page such that it becomes email#azlancoding.github.io
GitHub doesn't provide email address services for users. The domain github.com is used for GitHub staff and company usage, and GitHub doesn't offer email for github.io domains, either. Email is a service that requires extensive abuse management, both incoming and outgoing, and most sites don't want to provide that service as a result.
You can always set up an additional account, either on your own domain or elsewhere, that forwards to your real account. How to do that is probably more on topic for SuperUser, assuming you're setting up the software yourself.

Have you heard about Russia blocking IPs of Amazon’s servers (millions of them) in order to block messenger Telegram? There are a lot of cases when people are saying that their unrelated to Telegram applications, but located on Amazon servers, laid down as well as a consequence.
I was wondering if this teqnically possible situation. If I, for example, use Amazon’s server for my app, do I share an IP with others? Does it mean that if somebody blocks this IP to block another app, then I screw up as well? Or these are all fake sayings, and block is targeted enough to avoid this?
Is it possible to share IP on server among multiple applications?
Definitely. This is why transport protocols like TCP and UDP use port numbers. These port numbers serve as sub-addresses for the IP.
Some application protocols can even share the same IP address and port combination, like HTTP. An HTTP vhost (or a proxy) can direct the request to the desired server instance depending on the URL parameters.
So, when Internet censorship is applied on the IP address basis, it's not uncommon to filter more than intended.

I’m setting up a server on openshift. I’m on the Bronze Plan and have a pretty common setup, I assume. Tomcat 7 with a MySQL database, scalable cartridge, so nothing fancy. I’ve been able to setup the custom domain and I am aware of the missing SSL certificate. That stuff is pretty well documented.
But I could not figure out how to get mails working. I’m not talking about sending mails from the application itself, I’ve seen questions covering that topic. I mean mail in general, all mails from and to the domain (I’m more concerned with to the domain for now). I for example need a working info#speedapp.io mail address.
Sorry if that is bluntly obvious to anyone else. But I’m coming from a shared Tomcat hosting provider, where the web frontend for mails was already configure.
You need to sign up for email services at a third party host, you can not use OpenShift to host your email.

I'm going to create a game.
At first it will be the browser game.
Later it will be APP (Android, iPhone game).
At the server side I use nginx, apache, php.
=================
I need to inform online players about different events.
For example: one user is attacked by another one. I should inform him about that immediately.
Classical AJAX can't wrong there. I've read some about comet, web sockets and some other technologies.
But I still can't understand, which solution is the best for me?
Please, help me with the decision.
WebSocket should be the preferred option. It is a broadly supported technology.
It is a persistent, full duplex connection, compatible with all major browsers http://caniuse.com/websockets
maybe you could try Server Sent Events.
with SSE, a constant connection is maintained, until the page is unloaded, if something goes wrong with the connection or if you close the connection manually.
everytime something happens, e.g. a player is being attacked, you send an event command to the client, which then takes action depending on the event data.
although it does not work in every browser yet, it is a technique you could try
http://www.html5rocks.com/en/tutorials/eventsource/basics/ gives some further explaination on SSE and on how to set it up
Go with WebSocket. Using this, you can handle both the data sent from client browsers to the server (e.g. "user A attacks user B") and data sent from the server over a single channel. This saves server resources - and having a single technology is better than two separate ones (AJAX + something for the back channel).
Additionally, there are libraries for WebSocket for Android and iOS, so you could also attach native clients there in the future.
Since you'll need to distribute events to multiple clients at once, using something like Publish & Subscribe on top of WebSocket would make sense.
I suggest taking a look at Crossbar.io - it's an open source application router which does Publish & Subscribe out of the box.
Full disclosure: I work for Tavendo, the originators of the Crossbar.io open source project.

When I browse my home network with a bonjour browser, I see this _acp-sync._tcp bonjour service beeing advertised by all my AirPort base stations. Can anyone give me any insights on what this is for?
The only likely reference I can find for an ACP protocol is in the man page for natutil:
natutil uses the ACP protocol to detect, configure, and extract status information from Internet gate-way gateway way devices (IGDs) (such as AirPort Base Stations) on the local network.
I doubt you'll find out much further about it without firing up a packet sniffer as the dearth of information about it is a good indicator that Apple want to keep it proprietary.
Of course, I'd quite forgotten about that feature of Server. And Lion now contains the natutil(8) utility in the client, with more documentation (but inaccurate control of Airport base stations). _airport._tcp uses same port number (5009). Sadly, the IANA registry contains very sparse information on the formats of the TXT records in either case, so we lose beyond this point. :-(
