I am trying to connect to sftp server via ruby console.
Code snippet:::
Net::SFTP.start(IP, USERNAME, password: PASS) do |sftp|
.....
end
It throws the following error::::

I tried using Net::SSH as well.. Got same error.
But when i do sftp USERNAME and then it prompts for password. It connects properly when i give the password in terminal. But cant connect via ruby code alone.
Can someone throw some light on it?
Finally found the reason.. I was giving wrong parameter. it was user#host. My parameter was incorrect.
Thanks guys
Hello developer community,
I'm using AWS Cloudsearch (API version: 2011-02-01) and trying to upload and search from an app living on heroku, which means i need a proxy with a static ip so that i can whitelist it, but i'm having problems...
I'm using a Heroku add-on called Proximo. Here's Heroku's code example for setting it up with RestClient:
require "rest-client"
RestClient.proxy = ENV["PROXIMO_URL"] if ENV["PROXIMO_URL"]
res = RestClient.get("http://api.someservice.com/endpoint")
puts "status code", res.code
puts "headers", res.headers
I'm using the aws_cloud_search gem which uses Faraday to make requests, and im struggling to get a proper response from CloudSearch with my patch
# aws_cloud_search.rb
def self.create_connection(url, aws_access_key_id=nil, aws_secret_access_key=nil)
options = ENV['PROXIMO_URL'] ? { proxy: ENV['PROXIMO_URL'] } : {}
connection = Faraday.new url, options do |builder|
builder.use AWSCloudSearch::HttpCodeResponseMiddleware
builder.use FaradayMiddleware::EncodeJson
builder.use FaradayMiddleware::ParseJson
builder.adapter Faraday.default_adapter
builder.proxy ENV['PROXIMO_URL'] if ENV['PROXIMO_URL']
end
connection.headers['User-Agent'] = "AWSCloudSearch-Ruby-Client/#{VERSION}"
connection
end
I've tried many combinations of patch work seen here (among other places) to no avail. When i set up a proxy with the ip address provided by Proximo with port 80 (as they suggest), I get the following:
Faraday::Error::ParsingError: 757: unexpected token at 'invalid'

=> "http://nn.nnn.nn.nn:80" (i've obscured my ip address)
I take this to mean that the actual key being parsed is 'invalid', and i get this on search and document (i'm not using ssl). (i get html with 403 Forbidden without the proxy). I've attempted to print out the response body but I think the error is occurring before I can even print it out (as with the 403).
Anything obvious that I haven't tried or problems with my approach?
Thanks
The aws-sdk-core gem now supports the CloudSearch domain APIs (Search, Suggest, UploadDocuments). You should be able to install the gem and configure the client with a proxy:
require 'aws-sdk-core'
client = Aws::CloudSearchDomain::Client.new(
endpoint:'http://...',
http_proxy: 'http://...')
The client API reference can be found here:
http://docs.aws.amazon.com/sdkforruby/api/Aws/CloudSearchDomain/Client.html

Because of Vagrant's read-only file system you need environment set the variable SPRING_TMP_PATH to somewhere outside of the /vagrant directory
run this at the command line
mkdir ~/spring_tmp; export SPRING_TMP_PATH=/home/vagrant/spring_tmp
spring start
then run
spring status
if spring is now running then add the following line to ~/.bashrc
export SPRING_TMP_PATH="/home/vagrant/spring_tmp" # Temp PATH for spring

I got this error with RSpec. I had to mount /windows via SMB (cifs) from a shared folder. I also had to change the permissions on the shared folder to grant write access. You can either grant Full Control to Everyone, or Full Control to your Windows user, but then you have to mount with permissions.
mount -t cifs //10.0.2.2/aidc /windows -o credentials=/etc/samba/credentials,uid=500,gid=500
You also have to install Samba (cifs?) too in your Virtual Box.
I heard vboxfs is really bad and doesn't handle a large number of files.

It was working fine before, but this is a larger job I'm running. Is there some timeout that I need to set?
Thanks!
OK the problem was that the delayed_job timed out. I had to up the time limit with:
Delayed::Worker.max_run_time = 48.hours #2 days
in app/config/initializers/delayed_job_config.rb
I have a Ruby on Rails application that I am deploying on a computer running Mac OS X 10.6. The code where the problem arises is run by a delayed_job. The problem only occurs when it is run through delayed_job. If I run it within a console (rails console production) or call the API directly through cURL, it works without any problems. Also, the entire process works without issue in my development environment.
Basically, the code works in one place, but for some reason, fails where it has to work. I've searched and found a few resources, but none of the suggestions apply or make any difference. When I log into the server and run the commands, everything works. But for some reason when they are run/started by Capistrano, it doesn't work.
Any help is greatly appreciated.
Important notes:
Ruby version: 1.9.2-p0
Rails version: 3.0.1
delayed_job version: latest (from collectiveidea/delayed_job)
rest-client version: 1.6.1
Code:
class CallApi < Struct.new(:num)
def perform
log "Entering perform"
apinum = num || 5
log "ApiNum = #{apinum}"
results = attempt(2,10) do
ActiveSupport::JSON.decode(RestClient.get(API_URL, {:params => {:apinum => apinum}}))
end
log "Results retrieved. (count: #{results.count})"
end
def log(message)
Delayed::Worker.logger.info "[CallApi] #{Time.now} - #{message}"
end
end
Environment Config (note: the url is fake, but of the same form as the real one):
API_URL = "http://api.example.org/api_endpoint"
# Originally, I had "http://" before the beginning, but found a
# post mentioning that Net::Http.start didn't like that.
# So I tried it both ways.
# The same error occurs regardless of if the "http://" is there.
Call where the error happens:
RestClient.get(API_URL, {:params => {:apinum => apinum}})

The error occurs when the DNS resolution fails. Check if you can wget (or curl) the api url from the command line. Changing the DNS server and testing it might help.
I ran into a similar situation today - deploying an app to a mac os x server, and receiving the 'getaddrinfo' message when I tried to access an external api. It turns out that the error occurs when the ssh session that originally launched the app is no longer active. That's why everything works perfectly if you ssh into your server and run commands manually (or launch the server manually) - as long as you keep your ssh session alive, this error won't occur.
Whether this is a bug or a quirk in OS X, I'm not sure. Here's the page that led me to the solution - http://lists.apple.com/archives/unix-porting/2010/Jul/msg00001.html
All I had to do was update my capistrano task to launch the app using 'nohup'. So changing
run "cd #{current_path} && RAILS_ENV=production unicorn_rails -c config/unicorn.rb -D"
to
run "cd #{current_path} && RAILS_ENV=production nohup unicorn_rails -c config/unicorn.rb -D"
did the trick for me.
Hope this helps somebody - it was quite a pain to figure out!
I fixed this problem simply by closing and reopening the Terminal.
rest-client's RestClient needs the http: scheme when resolving the URL. It calls Net::HTTP for you, which doesn't want the http: part, but rest-client takes care of that.
Is the URL the actual one you are attempting to reach? example.org is a valid domain used for testing and documentation and is reachable; I'd expect the "api" and "api_endpoint" parts to fail and see that when I try to reach them.
require 'socket'
IPSocket.getaddress('example.org') # => "2620:0:2d0:200::10"
IPSocket.getaddress('api.example.org') # =>
# ~> -:7:in `getaddress': getaddrinfo: nodename nor servname provided, or not known (SocketError)
# ~> from -:7:in `<main>'
Here's what I get using Curl:
greg-mbp-wireless:~ greg$ curl api.example.org/api_endpoint
curl: (6) Couldn't resolve host 'api.example.org'
greg-mbp-wireless:~ greg$ curl example.org/api_endpoint

I got the same error when I check the localhost is set in hosts file it is somehow not set. Setting localhost to 127.0.0.1 solved it.
sudo vi /etc/hosts
>>
127.0.0.1 localhost
I restarted my computer (Mac Mountain Lion) and the problem fixed itself. Something having to do with the shell thinking it was disconnected from the internet I think.
Restarting your shell in some definite way may solve this problem as well. Simply opening up a new session/window however did not work.
To avoid this problem, we can bind to 127.0.0.1 instead of localhost:
bin/rails server -b 127.0.0.1
I was seeing this error unrelated to rails. It turned out my test was trying to use a port that was too high (greater than 65535).
This code will produce the error in question
require 'socket'
Socket.getaddrinfo("127.0.0.1", "65536")
For me, I had to change a line of code in my local_env.yml to get the rspec tests to run.
I had originally had:
REDIS_HOST: 'redis'
and changed it to:
REDIS_HOST: 'localhost'
and the test ran fine.
In my config/application.yml
I have changed this
redis:
url: "redis://redis:6379/0"
to this
redis:
url: "redis://localhost:6379/0"
and it works for me
I got the error while trying to develop while disconnected to the Internet. However, the website I was working on needs to be able to talk to some other websites, so it choked when it couldn't do so. Connecting to the internet fixed the error.
If all of the above fails, try to convert to UNIX Line Endings, or do:
brew install dos2unix
sudo dos2unix -c mac /private/etc/hosts
Maybe the hosts encoding is wrong.
hope this helps
I had this problem running rake db:create. This page clued me into the DNS issue. I checked my VPN connection and found it was disconnected for some reason. I reconnected and now rake worked without a hitch.
