Looking for someone with knowledge with GPO, registry edits, and other ways to have a windows 8 system use a minimalist IT policy. Giving only the minimum access to do the job. The wanted outcome is to be able to add the desktop to any domain and give a manual IP to the system. From there the local machine will only have access to chrome and internet explorer and only be able to access certain websites. I plan on taking an image of the final product to duplicate over multiple devices. I do not want to do this with active directory because I want the system to be restricted in case the system is not added to a domain.

Looking for an experienced sysadmin that can handle a vps servers (actually more). I have an application (website) that is developed in php using mongodb and many web services for getting data (mostly on request data). The system administrator should have strong knowledge in: - linux server administration (vps) - cloud vps - horizontal scaling - experience in setting up and maintaining apache server - experience in setting up and maintaining php5.6 and php7 - experience in setting up and maintaining mongodb with sharded cluster - experience in setting up and maintaining a git service - experience in setting up and maintaining a dns service - experience in setting up and maintaining an cloud email service - http/https security - other related things like: linux user rights, monitoring (disk and memory) The application has several zones for back office, mid office and front end over the same mongodb that should be sharded cluster. The developers should have access (read-and/or-write) only on the project that they are assigned to. I need to know that an account have access only to the zone that is assigned. I need backups for the application and for the database. I am looking and I need someone that is looking for a long term relationship. I know that there are setup costs and monthly maintenance costs (that I am very glad to pay), but this person should be there when needed (because I have had very bad experience with people that are not the when needed, like when the server is down or even when some critical functions are not working). PS: Right now we are using Aruba Cloud for VPS testing.

We currently have 2x Mikrotik CCR routers that are connected to a BGP provider each. We are having problems with some VPS' on our platform causing/being targeted by UDP flood attacks, etc. We would like someone to mitigate this problem by integrating a solution that can automatically resolve those issues: 1) Use FastNetMon (or any other open source DDoS protection tool) to monitor traffic from CCR (preferably using traffic flows, flexible on this). 2) Set it up in "watch" only mode to alert via PagerDuty if an issue occurs 3) After a week, if everything is okay, we will switch it into blocking mode, you'll have to configure ExaBGP integration so it can announce /32 prefixes to a BGP peer which will block all incoming traffic at our transit provider AND automatically blackhole in mikrotik 4) Slack notifications once something gets blocked! Thank you.

I have a Windows Server 2016 Technical Preview 5 in Azure that seems to time out after a certain period of time. You attempt to RDP in and you're unable to. It seems as if it went to sleep, which it didn't. The only way to regain access is to stop and restart the instance via the Azure Portal.
