I need a Server 2016 Tech Preview 5 that is a VM in Azure to connect to a VPN using PPTP to access an internal website and a file share. Azure does not support GRE so we need to figure out a way around this and changing the current PPTP protocol isn't an option. Maybe we can have the 2016 Server connect to something else that has GRE before it connects to the VPN server and then have that connect using GRE. Please don't apply if you don't have a solution.

We have an existing dedicated server running LAMP (Ubuntu 14.04.3 LTS & Webmin/Virtualmin) which serves CMS/PHP websites, client portals, email and mysql etc. We have 1 spare dedicated serve which is the same hardware and has Ubuntu 16.04.1 installed but is currently blank and unused. We're looking for a solution so that when Server 1 (the dedicated server already in use) needs maintenance, updates or if it fails then the second spare server detects this and takes over and serves the websites and other services. When Server 1 is then back online, Server 2 would then detect its presence again and sync any updates, file changes/emails or websites changes back to Server 1 again and then switch back so that Server 1 is serving the content again. We only have these two server available for this and no other hardware. The other problem is that we don't think we can use block level mirroring/DRDB or similar due to not having the right partitions setup already on the server in use. We're open to ideas and solutions on this but just need a simple and cheap solution that is reliable and won't corrupt or lose any data. We've already found a couple of potential guides to Heartbeat, corosync, pacemaker and keepalived but are unsure how to best use them and set them up without causing too much downtime on the active Server 1. This guide also mentions using rsync and looks reasonable and fairly simple but misses a couple of the requirements needed and also we're unsure if it is the best solution being a 6 year old post: We'd also need details of what is implemented and how to make sure it can be recreated in future if we add further servers or if we have a problem and need to reconfigure things. Thanks for any options on this.

【BACKGROUND INTRODUCTION】 Have you ever thought about "cracking" the visa/ticket application system using your technique? Do you see a huge and profitable market in it? Many people in developing countries chase after popular visas in developed countries. However, places for some are limited. Take Silver Fern Visa in NZ, for example -- only 300 places each year. Such visas are great opportunities for those who want to migrate to another country. They snap up sought-after visas once the applications are opened. The ones who do faster in the applications win at last. That's why there is a great opportunity in it. You must apply for a place on Embassy's website, and machine is no doubt faster than applicants themselves. What if you develop a software to help them with the applications? What if a software takes care of everything by automatically filling in information, proceed and submit the applications? You can earn a lot just by selling the places you grab. People are willing to pay, as long as you secure them a place under the quota. Some companies are already doing this job. The price for one place varies from 800 USD to 3000 USD. A lucrative business, isn't it? Imagnie that you have 100 customers... 【WHO WE ARE, WHAT WE WANT】 We are a startup based in Hong Kong. We have a great marketing and sales team. We are looking for a partner who can develop a program, e.g. a software, to help our customers grab places for these visas! 【REQUIREMENT】 1. Proficiency in coding, software developing and network operation. 2. Fast learner. 3. English literacy. Good communication skills. 4. Sense of responsibility. 【PAY】 AT LEAST 7000 USD for the first term (Australia visa system. September 2016, 20 customers). We expect three terms until Feb 2017. This is a long term cooperation -- the more systems you "crack", the more you earn. You can organize your own tech team, if necessary. 【HOW TO APPLY】 Please apply through Upwork. Tell us why you are a good candidate.

I need a c++ application written with QT5 framework to directly access the MT4 server of a broker and retrieve Forex-currency quotes. This must handle multiple brokers at once. For example: Pepperstone FX broker (demo IP = Setup direct TCP connection and retrieve the data the same way that MT4 terminal would do it. I don't want a bridge between terminal and c++. The task is to make an independent QT5 C++ application (MSVS2013 project) without the need of any MT4 software required to be installed.
