Hi Everyone,
I would like some help on a project please.
If I have 2 servers in different countries, both have SQL server express 2014 installed.
I would like to view a remote server connection between the two servers.
Will the connection be possible if I allow remote connections on both servers, or do I have to use a VPN between the two servers?
Thanks a lot for your help.

A VPN would be recommended.
SQL Server is usually only approachable from the local network. If it is approachable over the internet, you are taking a rather big risk.

i have one site with asp.net coding and Hosting plan (silicon House) Linux Base ...
so it's possible to hosting asp.net site with linux base server ///??
if yes then ... How....??

If mono is installed on that Linux server, things might work. Read ASP.NET | Mono[^]. (Note: I have never done that, and cannot provide further help.)

If you've written your site in .NET Core[^], then yes, you can host in on Linux.
If you've written your site in ASP.NET MVC 5 or earlier, then you can probably migrate to .NET Core, so long as you haven't used any features that are no longer supported:
Migrating From ASP.NET MVC to ASP.NET Core MVC — ASP.NET documentation[^]
If you've written your site in WebForms (.aspx), then you'd have to completely re-write it in .NET Core, or use Mono[^].

I want to build a cluster, functions like an ordinary cluster takes in requests and distributes the load among the connected computers. How to I begin a project..How to code it, Basic instinct is to use a lower level language such as C, but that seems a lot of work, Even if I use C I don't know how to handle the networking part or connecting computers. How must I begin and the steps I must take for completion of the project.
Thanks in advance

The construction of the cluster will depend on the problem domain.
e.g.
If you have a high volumes of small tasks e.g. a giant web server, then you should employ a load balanced cluster with an array of stateless web servers behind it.
If you have small volumes of very large tasks then you should implement an MPI solution which splits the task into pieces, shares the load across the cluster and then assembles the final result from the processed pieces. This is ideal e.g. for video rendering or large amounts of mathematical computation, data mining etc, deep learning etc.
Can you provide some information about your use case, and then I will be able to offer some additional information.

Is there one entry that will replace these 3 lines with 1 line for whitelisting in the local.cf file for SpamAssassin?
whitelist_from *@craigslist.org
whitelist_from *@reply.craigslist.org
whitelist_from *@sale.craigslist.org
Not sure how to do it, or if it can be done.

I just found the answer after searching for days. The format is:
whitelist_from *.craigslist.org
This is replace the 3 lines and be more efficient.

Hello,
I am using PC Helpware and VNC to connect remote desktops of client PC’s. I have set repeaters for that in my Web Server. I have set to ports say ‘X’ and ‘Y’ to Helpware and VNC respectively. Now the repeater ports are closing randomly.
I notice this problem when clients are unable to connect to the server. I don’t know why it is happening.
If I close and open the running repeater exe and then I can connect to clients without any problem.
Can anyone help me to solve this problem ?

I've setup a server I need to manage to allow RDP over the Internet. I would like to use this server to access and manage some of the other servers on my local network (ESXi 6.0 host). For some reason when I RDP over the Internet to my Win 2012 server I'm unable to putty from that server to other local servers.
Are there security settings that I'm missing?
Thanks,

I need to move a set of databases from a Windows 2008r2 server to a new Windows 2012 database server. I have looked at several articles but have not found the best one listing all of the complete steps in doing this the in a way that seems to have the complete process. Can someone direct me to a good article for me to follow in doing this?

Backup, copy, restore. What's the issue?
There are only 10 types of people in the world, those who understand binary and those who don't.

I understand what your saying about it being very easy but the main issue is we are creating a 200Rr2 server from scratch and want to ensure everything is done right. This includes server setup, settings, etc.

There is no way to know without doing it. I assume you are also upgrading SQL from 2008 to 2012? If so, it depends on if you are using anything in sql 2008 that is no longer supported in sql 2012.

Thank you for your advise. I will look further into our situation and try to get a better understanding of all of the moving parts before we even start with the database copying.

Hello!
Suppose you purchase a piece of server software and install it on a machine. Now, ideally I would like to tie it to the underlying machine, but it may not be a machine at all, it may be a VM.
Now, if you want to start up a second instance, I want to ensure that you are paying for that second instance.
Because of this, I need to find a way to distinguish them even though the underlying hardware may be the same.
I thought of using the PC name, but even that may be problematic because I can't be totally sure that *ALL* cloud vendors (hence, not just the VM vendors, but also their customers who, in turn, become sellers to my customers) will allow to change it.
Suggestions?
Thanks!

Hey
The common way to implement such a thing is using some unique data from the server to identify it.
For example, you can check the server MAC address when your software start, send it to your management server and find out if this server allowed to run your software or not.
You can also check if there more than one server with this MAC address, so on, but this is just an example nothing more.
Most software using this principle but real implementation can vary.

I'm a freelance, junior sys-admin who is currently tasked with setting up the hardware for a tech startup. We're hosting a software service and need a system solution that makes sense within our budget and requirements.
The ideal goal would be n + 1 design, high security, long-term high availability without breaking the bank. Budget is ~6k for initial round of investment towards gear only. Additionally funds will be allocated for a year of quarter rack space in a datacenter local to my location.
I'm a bit over my head with my current knowledgebase, and intend to bridge the gap with a lot of pre-planning over the next 60 days. I figure 60 days before ordering any gear, 30 days to have it all come in, and get it initially configured at the datacenter, then 90 days to build out our hosting interface and properly test the system before going production. 6 months would be nice, but 8 months is being allocated for project.
Okay, so onto the gear and setup:
(2) Cisco SG-300-10 Switches, 1 wired & active, the second rack-mounted ready for wiring in case of failure.
PFSense:
Primary <> Secondary
With heartbeat in load-balancing + fail-over mode
Nginx Load-Balancers:
Primary <> Secondary
Configured in PFsense for failover
App/Data Servers:
A 4:1 ratio of active to failover App/Data Servers. I think failover can be configured with the Nginx Load-Balancer else PFsense.
Initial deployment is the two firewalls, two LBs, and 4+1 App/Data servers, with expectations to grow more App/Data as demand increases.
The service runs on LEMP stack. A master to master MySQL link between each A/D and the failover exists on separate partitions, separate instances of MySQL. It continuously synchs database with each active A/D, ready for activation in the event a LB declares an active dead. Higher resources in the form of more memory, higher thread count CPU, and n(A/D) hard disk space is allotted for failover.
Additionally, I plan to use an Anycast DDos prevention serviced by my colocation provider. I am wondering what drawbacks there are to my model.
The first 3-4 months is designing and deploying the system, the next 3-4 is linking the system to the software with the developers so that we can auto-provision services. I plan to utilize scripts heavily for this.

Hi,
Scenario: There are two isolated networks A and B with systems and applications (all Windows environment)
Network A
- Client AC1
- Server AS1
Network B
- Server BS1
"AC1" initiates a VPN-like connection and connects to Network B.
"AC1" then connects to a web application hosted on "BS1"
"BS1" in turn needs to connect to a Web Service hosted in "AS1" using Network A credentials of user on "AC1".
Is this possible? What do we need to ask the Network team of A and B to do in order to achieve this?
Thanks in advance.
