I am trying to use Plesk’s ODBC function to connect to my personal database and am unable to do so. I keep getting the error that the server cannot be found. I have allowed access to remote connections, created login credentials, and updated the firewall to allow connections through port 1433. I also tired using port forwarding through Cox Wi-Fi.
I can connect to my personal database from my own, separate server using both the name of my computer or the private IP address. However, when trying to connect from Plesk, I am unable to connect when trying the computer name, private IP, private IP with specifying the port, public IP, and public IP when specifying the port. Nothing seems to work.
Any help is greatly appreciated.

Is there any way for me to connect to a VPN without having it use my DNS? My internet provider where im connected can only use the DNS to connect to a separate server, which then connects to the internet as the router only interacts with that server, so if I change my DNS, my connection instantly stops working.
Is there any service that connects to a server without DNS as a VPN, or even some way to set up a proxy to go to another server after it interacts with my DNS?
Tried Changing DNS, no connection using cloudflare or google DNS servers (1.1.1.1, 8.8.8.8), Hotspot Shield VPN wouldn't connect, VPN from my home network wouldn't connect.
So, your ISP allows DNS traffic only to its server. And you want to by-pass this limitation.
Solution 1: SSH Proxy
ssh -D 5000 user#host
Now, you can set your applications to use proxy on socks5://localhost:5000
You must set "Proxy DNS on socks5"
This proxy goes throught the SSH server
Of course you need SSH server somewhere to connect to.
Solution 2: DNS over HTTPS
https://en.wikipedia.org/wiki/DNS_over_HTTPS
https://manpages.ubuntu.com/manpages/bionic/man1/dnss.1.html
It should work because your DNS packages go as HTTPS packages.
Solution 3: VPN or other services like nordvpn
It should work also since packages go encrypted to the VPN.
Actually, VPN should work without your ISP DNS as long as you connect to the VPN IP address instead the hostname.
Finally
Solution 2 seems to be the only one you are able to perform without external services.
I'm trying to connect to a remote Firebird database "test" (alias already added). It is not an embedded server, and is installed on VM with IP 192.168.1.147.
Here is my connection string:
User=sysdba;Password=masterkey;Database=test;DataSource=192.168.1.147
However I got an error:
FirebirdSql.Data.FirebirdClient.FbException (0x80004005): Unable to complete network request to host "192.168.1.147". ---> Unable to complete network request to host "192.168.1.147".
I've done some research on that but haven't got a clue yet. Some help needed. Thanks
My IP address is 192.168.2.108, and I can ping that server IP successfully
Make sure that
Firebird is running
Firebird is listening on port 3050 on the specified IP (or on 0.0.0.0)
Your firewall allows access to port 3050
You're using the correct host name
For Linux, the Firebird port is closed by default. You need to modify RemoteBindAddress in /etc/firebird/2.5/firebird.conf from
RemoteBindAddress = localhost
to
RemoteBindAddress =
and restart service.
Make sure you have excluded tcp port 3050 in VMs' firewall.
Ok. I think your connection to firebird is faililing because the firebird client looks up the network service file by name and does not find gds_db in the services file.
If your connection string refers to the host by using IP, the Client might fail to identify it because it gethostbyname() and not by IP
Manually include this in the file and you should be fine.
C:\windows\system32\drivers\etc\services
following scenario with a firewall inbetween this PCs:
Client PC
IP 10.10.140.100
Subnet 255.255.0.0
Gateway: 10.10.0.254
Server PC
IP 10.40.140.100
Subnet 255.255.0.0
Gateway: 10.140.255.254
The communication itself is already working (ping, using a WebClient) so don't worry too much about that.
I'm facing a connection problem connecting to a named instance (in this case "WINCC") from the Client PC to the Server PC(SQL Server 2008 R2) using the following connection string in the application (Database name is correct, have checked that!):
strserver = "10.40.140.100"
strConnectionString = "Provider=SQLNCLI10.1;Integrated Security=SSPI; Persist Security Info=False;Initial Catalog=" & Database & ";Data Source=" & strServer & "\WINCC"
Circumstances:
Microsoft SQL Server 2008 Native Client is installed on the Client PC
The windows user used on the Client PC is existing on the Server PC and part of the necessary User Group (in this case SIMATIC HMI Group because of WinCC)
I have looked up the dynamic port used by the sql server which is 49181 and the port was opened in the firewall of the network
This has worked in every other network environment till now but something is still somehow blocking the access in the network
The script is crashing with the following error:
"SQL Server Network Interfaces: Error locating Server/Instance Specified [xFFFFFFFF]" when attempting to establish the connection to the database (.Open command).
I'm 99% sure it has to do something with a port not opened. I have seen several times that the UDP Port 1434 of the Sql Browser service has to be open for . Is this also relevant when using the SQL NAtive Client Provider? Or should I try to name the port specifically in the connection string? (Like "10.40.140.100,49181/WINCC"?)
Any comment is appreciated, thanks!
Best regards,

Using a Dynamic port can often cause issues. If you have an App server connecting to the SQL server inside your network I would suggest using a Static IP on the SQL server and then route it through the firewall as defined. Also as you said I would define the TCP/IP port in your connection string.
This would be set up in SQL Server Configuration manager under SQL Server Network Configuration. Select Protocols for . Right click TCP/IP and select the IP Address tab. Make sure all TCP Dynamic Ports are set to 0. Under IPALL, set the TCP Port to the static IP address. Once that is done, you will need to restart the SQL server service.
i am trying to set up a site with xampp. i have succesfully connected to the instance via remote desktop and installed xampp and python (needed for my php script). now i am trying to find a way to connect to the instance's localhost via a browser in my local computer with the provided private and elastic IPs but no succefull attempt yet. i would like to configure that with a static IP or domain name (i suppose the elastic or private IP?) because my site will be used for http requests.
did you allow port 80/443 in your security group?
did you start the xampp server?
when logged in via remote desktop, are you able the open 'http://localhost' in a remote browser?
your elastic IP is the address reachable from public
private IP is the address reachable from within the availability zone
So I have this issue. The issue is I am unable to connect to my red5 server from a remote client. I also have not found any tutorials on how to install red5 so that remote clients can connect to it. However, here is what I have done...
Inside My MXML Flex File I try to connect to the computers IP that the server is running on(My Server is running from within Eclipse). The line for connecting looks like this netConnection.connect(rtmp://192.168.2.12/myApp, true);
All that happens is after a lot of minutes go by, I just get NetConnection.Connect.Failed and there is no log being output by Eclipse. Almost like it never even registers the connection that the remote client is trying to make.
The other interesting thing is that I am ABLE to connect to my Red5 Server using a different computer within my local home network just fine. But only when it is remote I am unable to connect.
I have changed my Red5-web.properties file and added this...
webapp.contextPath=/myApp
webapp.virtualHosts=*, 127.0.0.1, localhost, 192.168.2.14, 174.122.104.3
The 174 one is my website where the Flex Swf Resides on.
I think maybe somehow my computer is not setup or configured to allow these remote connections and is rejecting them or something, I'm not quite sure why a remote client can't connect. Does anyone have any idas?
Your help is greatly appreciated.
You may uninstall the red5 and reinstall it.
When it ask you the server ip address type your server's LAN adress (192.168.2.* or 10.0.0.* whatever). This solved my problem.
In my opinion, if you have at least one domain name that you own, the best way for you to go is to set up an Apache Http Server to your server machine, and create subdomains for both red5, rtmp and rtmpt. Make the Apache handle your incoming requests, and decide their correct routing there.
In case you don't own a domain, or the previous way is too time-taking to set up and get it work, you should just make sure that the ip address you're trying to connect to is not an internal IP.
In your example above you are trying to connect from the client to a 192.168... address. If you try to connect to it from within your LAN, it works, since that ip there is registered to your machine.
But when you take your notebook to your neighbor, and using his internet connection to access your site and connect to red5, the client (flex application) will also try to connect to that 192.168..., and your neighbor's router has no idea about your LAN, probably it doesn't have such an internal IP address either, but SURELY cannot connect to your server.
So instead of using 192.168... in your connection string, you should try using your external IP address (the 174... one):
netConnection.connect("rtmp://174.122.104.3/myApp", true);
This will work always, as far as you have a static IP address.
Also make sure, that your red5 server is accessible over the 80 port, or if it's not, specify the correct port number there.
For that you can do following thing...
These steps I took and it's solved my problem...
1.During the installation, you must have given ip 127.0.0.1 (localhost) and port :5080
2.firstly open the port (5080 and 1935) on firewall.
Visit http://windows.microsoft.com/en-in/windows/open-port-windows-firewall#1TC=windows-7
3.Now to go red5->conf->red5.properties and open this file in notepad++. (or any other editor)
4.repalce http.host and rtmp.host ip with your ip address (ipv4)
5.start the red5 service.
6.Now check http://yourip:5080
It will start working, and you can access it from other system also (in the same network Obviously )
