How do I connect to the database geoip Haproxy?
an example.
Haproxy decides at ip country and city, and modifies http headers for transmission to the backends:
reqadd X-Country:\ Country
I think what you want is something you should look for in a dynamic dns, like route53 where it can detect the ip and route to the closest load balancer. You can however setup acl requests in haproxy. More in section 7 of the man pages: http://haproxy.1wt.eu/download/1.5/doc/configuration.txt

I have a Go service, deployed on Heroku, which pulls the IPv4 address from the request header successfully.
ip := net.ParseIP(strings.Split(r.Header.Get("X-Forwarded-For"), ",")[0]).String()
I have deployed the identical code as a service to Google Cloud, and the IP addresses are frequently IPv6 in about 25% of the time. After examining the full Request Header, there is no IPv4 address available anywhere, only IPv6.
Heroku's Request Header X-Forwarded-For ALWAYS contains the IPv4 address, yet Google Cloud doesn't. Does anyone know a way to force the IPv4 format for Request Headers in Google Cloud?
Clients can connect via IPv4 or IPv6 but not both. Only one address family will be used by the client and only one IP address will be recorded by the proxy.
Additional information:
Heroku does not support IPv6 so clients are forced to connect using IPv4. reference
If you only want IPv4 connections, do not enable the IPv6 frontends. However, I recommend using IPv6 where possible.
There might be a post which I am looking for. I have very limited time and got requirement at the last moment. I need to push the code to QA and setup elasticsearch with admin team. Please respond me as soon as possible or share the link which has similar post!!.
I have scenario wherein I will have multiple elasticsearch servers, one is hosted on USA , another one in UK and one more server is hosted in India within the same network(companies network) which shares same cluster name. I can set multicast to false and unicast to provide host and IP address information to form a topology.
Now in my application I know that I have to use Transport cLient as follows,
Settings settings = ImmutableSettings.settingsBuilder()
.put("cluster.name", "myClusterName").build();
Client client = new TransportClient(settings)
.addTransportAddress(new InetSocketTransportAddress("host1", 9300))
.addTransportAddress(new InetSocketTransportAddress("host2", 9300));
Following are my concerns,
1) As per the above information, admin team will just provide the single ip address that is load balancer ip address and the loadbalancer will manage the request and response handling .I mean the loadbalance is responsible to redirect to the respective elasticsearch server . Here my question is, Is it okay to use Transport client to connect to the host with the portnumber as follows ,
new TransportClient(settings)
.addTransportAddress(new InetSocketTransportAddress("loadbalancer-ip-address", “loadbalance-port-number”)) ;
If loadbalancer will redirect the request to elastcisearch server what should be the configuration to loadbalancer like, we need to provde all the elasticsearch host or ipaddress details to it? so that at any given point of time , if there is any failure to the master elasticsearch server it will pick another master.
2) What is the best configuration for 4 nodes or elasticsearch servers like, shards , replicas and etc.
Each node will have one primary shard and 1 replicate ? which can be configured in elasticsearch.yml
Please replay me as soon as possible.
Thanks in advance.

We've been recently getting hammered by this Firefox plug-in. It sends a fake IP in the headers so when our nginx web server picks up the IP it is a fake one.
Is there any way to get a real IP address or block out requests that have this plug-in installed?
There is actually no client IP entries in any HTTP Headers. There are only some un-official proxy headers which are added to a request, so that a proxy server can tell you the real ip of the connecting client (since the tcp socket will only reveal the IP address of the proxy server).
The plugin you linked to adds those proxy headers, to "fake" a proxy request, by adding a X-Real-IP: 1.2.3.4 or X-Forwarded-For: 1.2.3.4 header to the request. But no one forces you to use that IP address (which can be fake, like the 1.2.3.4 example here), you can always use the IP address of the socket that initiated the connection - which will be the client's real IP address if he uses the mentioned plugin.
Within the location section of your nginx configuration, you get the socket IP address through the $remote_addr variable. To retrieve the "fake" IP address, you can use $http_x_forwarded_for or $http_x_real_ip variable.
If you are using any application/cgi backend, you usually can examine the full headers and the socket IP address (i.e. in PHP you should check $_REQUEST and $_HEADERS variables)
The title says almost everything. I want to use apache under windows and then redirect one or more domains to my computer using a service like No-IP. Is it possible?
Yes you just need to set port forwarding to your local machine (PORT 80 for HTTP, 443 for SSL, 21 for FTP ( if you want to run a ftp server aswell)) on your router, and set a dynamic dns there that points to NO-IP. Most likely you can add one DynDNS entry.
Yes.
You don't even need a Dynamic DNS service (like no-ip) if you have a static IP address. In that case, just register a domain name and create two DNS records -
NAME TYPE VALUE
example.com. A public.ip.address.here
www.example.com. CNAME example.com.
Most ISPs now assign static IPs (even if they claim otherwise), and if not, you can get one for a small fee ($5/month extra). Or upgrade your account to business class.
This way you don't have to introduce another layer (Dynamic DNS) into your set up.
Then install a WAMP such as - xampp (really popular here) - UniformServer -
Wamp-Developer Pro (the one I use) -
WampServer (another good one)
You'll also need to port-forward your router (ports 80 and 443) to the LAN IP, and create two rules in the Windows Firewall to unblock incoming port 80 and 443 requests.
The only thing that can go wrong is if your ISP blocks incoming port 80 (http) and 443 (https) requests. You can call and get them to unblock that, or again, update the account to business class to remove all the headaches.
I need to get the ip address of the users of my website, because I need to present localized content according to country.
I have a load balancing server and because this I use the HTTP_X_FORWARDED_FOR to get the ip address, its ok, but since I set the HTTPS for the entire site I cannot get the HTTP_X_FORWARDED_FOR data, it returns empty, and only can get the REMOTE_ADDR, but this returns the Load Balancing Server ip address and not the user ip address.
How I can get the user's ip address when using load balancing and HTTPS?
I'm using ASP.NET 2.0
I just discovered that I'm having the exact same problem. In this question they suggest to use HTTP_CLIENT_IP. I haven't tested it myself, let me know if this works.
