I have a website that holds my database and it's been down for about a month and I need it back up asap. Apparently, two of my Instances were compromised and I asked Amazon to give me clear instructions for a new developers that I hire. I am not technical so I need you to help. Please quote me on how long it will take you to accomplish this and get my site back up and running. This job will not be complete until my website is back online. More info upon awarding you. Here's what I got from Amazon support. Step 1. Building a secure foundation for your website with a custom security group: Your two most recent instances have been blocked from communicating with the outside world due to abuse reports. All servers or instances have ports they use to communicate with the outside world. There are 65,535 ports, although not all of those are used, the most commonly used ones tend to be within the first thousand. Websites use ports 80 and 443 to talk to people browsing the internet - it...

Sample application needs to use them for RTSP as done by C++ desktop application -Client implements real-time streaming protocol (RSTP) -Server application captures the server machine desktop, encodes it in FFMPEG/AMF format and writes the stream in...

I'd like to test this tcp/ip stack,   [obscured]  /ejip/index.jsp   [obscured]  /doc/ejip.pdf on an arduino. I'm not very familiar with java but it doesn't seem like the code is inextricably tied to java (use of java specific features, garbage collector, library, etc).. so perhaps its relatively simple for someone who knows both languages, to convert the dozen or so java files to something c compatible.

The perfect candidate should be familiar with installing and maintaining SQL server express 2012, and also be familiar with basic windows tasks like opening firewall ports and starting and stopping services.

You will be expected to call clients and schedule times and then use GoTo Meting or TeamViewer to perform a SQL Server Express 2012 install and also run some proprietary MSI installs. Successful candidate must answer these questions in his cover letter: 1) You have installed a sql server on the server computer, the program client works great on the server. However, the other client computers cannot talk to it. They can however see a UNC path on the same network, where might you look to see why SQL server cannot be reached by the client computers although they're on the same network? 2) The app quits suddenly and throws an error that says "...

My MS Access front-end is getting time out issue with MS SQL Server Login error. I have attached the messaging that we get. I'm trying to work with IT to resolve the issue since I'm a vendor without success. It normally happens at the "busy" time of the day 11am - 3pm (not sure why) but they do not get this message. Especially any documentation that you may have on this issue since it takes an Act of Congress to get anything done with the government agencies.

Hey, we are looking for a very knowlegable network security expert. we host Minecraft Servers (TCP-Gaming Traffic) and want to secure them from DDoS attacks. Right now we use a reverse proxy mitigation service that adds lags to our gameplay. That is why we want to build our own solution. We need to deal with 5-6 GBit/s of TCP traffic and if there's an attack up to obviously a lot of incoming traffic (maybe 15 Gbits). My idea is to have one powerful server that access as a reverse proxy for our applications. We need I guess a hardened kernel and a powerful firewall that stops syn flooding, ack flooding etc. UDP Traffic will be blocked out in the backbone since we don't need it. Also all other ports and typical vulnerabilites should be closed. I'm looking for someone who has experience in this field and can propose a setup and help create it. It is important that the system runs lag-free and unnoticable to players. First step would be to configure the hardware, wait for the har...
