I am trying to check if the content type of the resource on my server at s3 has a valid image/jpeg content type. I used the code fromhere but I keep getting the:
Errno::ECONNREFUSED:
Connection refused - connect(2) for nil port 80
The link to my s3 image is as:
https://s3-us-west-2.amazonaws.com/cu-prototype-content/course-content/user-profile-images/BillSKenney-128.jpg
Is there something I need to change in my code?

I have tried changing the port the database (Which I think it’s what it’s trying to connect to) from port 5432 to 5488 but I get the same error. I have read other stack-overflow posts on this error message but they haven’t worked either.
I have also tried to speak with the company that made this project but as is understandable since this is an open source project of theirs from which they make no money it is not in their priorities to fix this issue.
So hopefully one of the brilliant minds roaming this site can help me out.
If you want more info on what the repo is for
Bringing data from wearables and medical IoT devices to FHIR solutions
I see container_name: timescaledb in docker-compose file. Hence host will be timescaledb and default port 5432 if you are trying to connect from another container in same network

I am working on chef(devops) where I have a helper library with the following code in it

message << "Chef run failed on #{node_name}\n"
Net::SMTP.start('localhost', 25) do |smtp|
smtp.send_message message, 'chef#chef.io', 'xyz#test.com'
end
end
end
end
But whhen I run the recipe I get

I tried changing port to 90 and some other options I keep getting same error.There are some solution available on few posts on stackoverflow already but all of them are talking about some other .rb files which is not present on my dev environment.

You would need to have an actual SMTP server listening on localhost and I'm guessing you don't have one. Without more information it's hard to say though. If you don't want run your own relay server, you can find instructions all over the internet for setting up outbound SMTP via GMail, Amazon SES, Sparkpost, Sendgrid, and may more.
While attempting to open a TCP connection to graph.facebook.com, I receive the following error:
Failed to open TCP connection to graph.facebook.com:443 (getaddrinfo:
Name or service not known)
TCPSocket.open(conn_address, conn_port, #local_host, #local_port)
rescue => e
raise e, "Failed to open TCP connection to " +
"#{conn_address}:#{conn_port} (#{e.message})"
end
}
Help me with this error
I'm using omniauth with Rails 5.0.0.beta3
Start by checking your network configuration.
Run this command on your terminal:
dig +short graph.facebook.com
If you do not get any IP address, your system don't know how to resolve this and the problem is not related to Ruby.
In addition to that as mentioned by Dawood Awan in his comment, opening a TCP connection to the port 443 is usually not a good idea, I am pretty sure facebook is excepting an HTTPS Connection.
I have been using flume for a while now, I have got agent and collector running on same machine.
Configuration
agent: exec("/usr/bin/tail -n +0 -F /path/to/file") | agentE2ESink("hostname", 35855)
collector: collectorSource(35855) | collector(10000) { collectorSink("/hdfs/path/to/sink","name") }
Facing issues in the agent node:
2012-06-04 19:13:33,625 [naive file wal consumer-27] INFO debug.InsistentOpenDecorator: open attempt 0 failed, backoff (1000ms): Failed to open thrift event sink to hostname:35855 : java.net.ConnectException: Connection refused

I dont understand why the connection is refused. Are there any system level changes that needs to be done ?
Note: the collector is listening to the port but agent is unable to send data through the 35855 port.
Can anyone help me with this problem.
Thanks
If you are running both the agent and the collector on the same box, you should be using localhost as the address.
agentE2ESink("localhost", 35855)
