Following exception was thrown while trying to execute $facebook->api('/me')
Uncaught CurlException: 6: Could not resolve host: (nil); Host not found thrown in C:\wamp\www\demo\php-sdk\base_facebook.php on line 1027
I figured out that my localhost was unable to resolve graph.facebook.com because my localhost runs on machine connected to my college network which is behind a proxy server.
One of the solutions I thought of that I need to forward all the requests made by my web application to my localhost to the network proxy server and then retrieve and process the result at localhost.
Kindly suggest how to proceed.

I have this server, client code in which we run the server as a subprocess in py.test and create a client object and connect it with client.
But I am getting the Connection Refused error, when I am tracing it to open() function wherein the socket is trying to connect to ip and port.
There a comment is mentioned that For Connection refused errors, work around startup races.
What are the different ways, I can fix the startup race issue?

"psql: could not connect to server: Connection refused" Error when connecting to remote database
The oc port-forward command is forwarding from only your loopback interfaces.
If you are running your client on the same machine where the cluster is running, then use localhost as your "Host".
If you are running your client on a different machine, they you need more network redirection to get this to work. Please see this post for more information as well as work-arounds for your problem: Access OpenShift forwarded ports from remote host
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.

So I have this problem where my node application that is ran by Docker in elasticbeanstalk cant establish a connection with mongoDB instance that is in another elasticbeanstalk environment under the same application(it deployed and ran with Docker aswell).
I have made sure that both of them are in the same VPC and that the mongoDB instance accepts inbound connections from the security group that the node application is under(inbound connections are accepted on port 27017).
Node application uses mongoDBs private IP in the connection string. Should work because they are in the same VPC.
Somehow the node application cant connect to the mongoDB instance and it throws the same error always.
*** DATABASE ERROR: MongoNetworkError: failed to connect to server [private-ip-here:27017] on first connect [MongoNetworkError: getaddrinfo ENOTFOUND private-ip-here private-ip-here:27017] ***
Can anyone give me advice what am I doing wrong ?
Most likely reason would be not configuring mongod.config file in etc directory.
There would be something like :
net:
bindIp: 127.0.0.1
Comment the bindIP or replace it with your server's IP Address.
I'm getting the following error when trying to deploy a ZIP file to a remote FTP server. I tried connecting to the server using an FTP client (filezilla) and all goes well.
Also, when connecting to a public ftp like ftp.belnet.be connections work fine.
I'm trying to send the file to a VSFTPD server behind a router using port forwarding. Again, this works fine from any location using Filezilla, phing is not connecting though...
BUILD FAILED
/deployment/build.xml:60:12: Could not connect to FTP server x.x.x.x on port 21: Connection to host failed

this was a firewall issue that has been resolved.
