I am trying to test which server serves a request however the setup has a load balancer between the server and client. How would i go about getting the IP address of the server rather than the load balancer. So far on the local machine i have tried although i know the middle two are for the client ip
ip1 = #env['REMOTE_ADDR'] -- returns 127.0.0.1:3000
ip2 = request.ip -- returns 10.0.2.2
ip3 = request.host_with_port -- returns 10.0.2.2
ip4 = Socket.gethostname -- returns precise32 (vm name)
Don't want to test this live until i am sure. Apologies if there's any detail lacking. If any more information is required just say the word.
Unless the server sets an HTTP header with the information you can't. That's the whole point of the load balancer, right?

When I store IP of client using req.ip and req.remote_ip then it showing different result when request twice using same device and internet connection.
for first req it returns:-
2402:8100:3092:16f4:1:1:cd28:307f
for second request it returns
27.97.134.92
which is ipv4.
Is there any way to get either only ipv6 or only ipv4 address?
I used symfony 1.4 to create my application.
I'd like to get the IP adress of the current server to put it within soap request
So, how can i get the IP address of the current server?
For most situations, using $_SERVER['SERVER_ADDR']; will work. If that doesn't work you can try $ip = gethostbyname(gethostname());
If you have access to the $request object and it is a sfWebRequest (typical request from a browser) you can use:
$request->getPathInfoArray()['SERVER_ADDR']
Premise of the following method: your domain name has only one IP resolution
Using PHP:
gethostbyname($_SERVER['SERVER_NAME'])
$_SERVER['SERVER_NAME']will generally return your domain name (server_name / ServerName is configured in Nginx / Apache server), and then use gethostbyname().
About $_SERVER['SERVER_ADDR'], it often return a LAN IP address (I only have one server, one domain name, no reverse proxy; cloud server).
About gethostname()
In the test, it returns the name of the server (host name, not the domain name you use), and then uses gethostbyname(), will return a LAN IP.
More can be used https://checkip.amazonaws.com/ Get the current IP.
I am working on a project whereby we have sites (developed with ruby on rails) hosted on an Ubuntu server using tomcat. We want these sites to make HTTP calls to a service developed using Nancy. We have this working locally whereby the service is hosted on a machine that we can call within our network. We cannot however get it working when live. Here is an example call:
def get_call(routePath)
started_at = Time.now
enc_url = URI.encode("#{settings.service_endpoint}#{routePath}")
uri = URI.parse(enc_url)
http = Net::HTTP.new(uri.host, uri.port)
req = Net::HTTP::Get.new(uri.request_uri)
resp = http.request(req)
logger.bench 'SERVICE - GET', started_at, routePath
return resp if response_ok?(resp)
end
When working locally the settings are as follows:
settings.service_endpoint = http://10.10.10.27:7820
routePath = /Customers
When we upload it to the server we use the following:
settings.service_endpoint = http://127.0.0.1:24099
routePath = /Customers
We currently get the following error:
SocketError at /register
initialize: name or service not know
with the following line being highlighted:
resp = http.request(req)
Are we completely wrong with the IP being called. Should it be 127.0.0.1, localhost. 10.10.10.27 or something entirely different? The strange thing is we can do a GET call via telnet in our Ubuntu server (telnet 127.0.0.1 24099) so that must mean the server can make the calls but the site hosted on the server cannot. Do we need to include a HTTP proxy (have read some reference to that but dont really know if its needed).
Apologies if its obvious but we have never tried anything like this before so its all very perplexing. Any further information required just let me know.
We changed the service_endpoint to localhost and it worked. Not sure if this is because it didnt like "http://" or some other reason. Any explanation as to why this is the case would be much appreciated, just so we know. Thanks!
I have a rails application that makes calls to another server via net::http to retrieve documents.
I have set up Nginx with secure_link.
The nginx config has
secure_link $arg_md5,$arg_expires;
secure_link_md5 "$secure_link_expires$uri$remote_addr mySecretCode";
On the client side (which is in fact my rails server) I have to create the secure url something like:
time = (Time.now + 5.minute).to_i
hmac = Digest::MD5.base64digest("#{time}/#{file_path}#{IP_ADDRESS} mySecretCode").tr("+/","-_").gsub("==",'')
return "#{DOCUMENT_BASE_URL}/#{file_path}?md5=#{hmac}&expires=#{time}"
What I want to know is the best way to get the value above for IP_ADDRESS
There are multiple answers in SO on how to get the ip address but alot of them do not seem as reliable as actually making a request to a web service that returns the ip address of the request as this is what the nginx secure link will see (we don't want some sort of localhost address).
I put the following method on my staging server:
def get_client_ip
data=Hash.new
begin
data[:ip_address]=request.ip
data[:error]=nil
rescue Exception =>ex
data[:error]=ex.message
end
render :json=>data
end
I then called the method from the requesting server:
response = Net::HTTP.get_response(URI("myserver.com/web_service/get_client_ip"))
if response.class==Net::HTTPOK
response_hash=JSON.parse response.body
ip=response_hash["ip_address"] unless response_hash[:error]
else
#deal with error
end
After getting the ip address successfully I just cached it and did not keep on calling the web service method.
How to get my own IP address with Rails?
When I do it like this I got: 127.0.0.1
#ip = request.remote_ip
Is there any way to get the Public IP?
Try:
require 'socket'
ip=Socket.ip_address_list.detect{|intf| intf.ipv4_private?}
ip.ip_address if ip
I believe request.env['SERVER_NAME'] works, if you want to reflect the server base address back
Call the page using your IP, not localhost. I.e, 192.168.2.9:3000 in case of the default development environment would yield:
request.env['REMOTE_ADDR']
#=> 192.168.2.9
or:
request.remote_ip
#=> 192.168.2.9
As your request is local to the server, it returns the "localhost" address, i.e. 127.0.0.1.
If you request it from a machine hosted on the internet, it will give you a static IP of the remote server.
If you want the static IP of own internet then visit http://ping.eu and you can see your public IP.
Try this:
request.env['REMOTE_ADDR']
This does not answer this question. I think someone else can find this answer helpful.
Problem:
I am developing a mobile app. So, When I debug/hot reload/live reload the app in real mobile device. Images url does not work with localhost:3000.
Images works with ip like this: http://192.168.0.102:3000/user/1/profile-223hfkj33.jpg
Problem is Every time I turn on laptop and connect to wifi router, laptop ip changes. So, every-time I need to change asset_host in environments/development.rb file.
Looking at previous answers I found a solution:
Solution:
in environments/development.rb I write this code:
server_address = "#{Socket.ip_address_list.detect(&:ipv4_private?).try(:ip_address)}:3000"
config.asset_host = server_address
puts "Server address: #{server_address}"
# when I run `rails s`, this line prints server address in console
So, It sets asset_host like this: 192.168.0.102:3000
And when I turn on laptop, laptop gets new ip address and it works.
