System: I have 2 Debian 9 clean installs with Bind9 on both.
Problem: I am not sure if this is a issue or not but what is happening is ns2 is being queried before ns1.
Domain: intelacyber.com
Question: Is this normal and if not how can I fix this?
If you need any other information please just let me know, thank you!
In this situation the problem was that I had a A record type that pointed to the ip address of ns1 in the ns1 record but not the ns2 record.

I am trying to setup monitoring in local as mentioned in https://cadenceworkflow.io/docs/operation-guide/monitor/#instructions
Having these errors for http://host.docker.internal:9098/metrics, http://cadence:9090/metrics as shown in below image.
Can please let me know how we can resolve this, Thanks
Endpoints state
9090 is Prometheus itself. Are you configuring a different port? https://github.com/uber/cadence/blob/68fb2e60d1a2bff77c66acf60c954c9d19f9e5f5/docker/docker-compose-es-v7.yml#L14
But anyway, this is not something important so if you like, you can ignore this error.
9098 is the client sdk . The doc is assuming that you are setting it up correctly: https://github.com/uber/cadence-java-samples/blob/cdd43b6a65bf537ef6c77262a56cd22308d75e06/src/main/java/com/uber/cadence/samples/hello/HelloMetric.java#L53

Just realized that geoip was present by default within the nginx-ingress in the context of kubernetes; that is, looked around, being new into nginx geoip, I don't have much clue about how to benefit from this
Firstly, is there any declarative setup to effectively have it working ? A configmap setup, or so ?
Secondly, how such info is passed from the nginx-ingress to an app ? Is the info present in the headers ? is there any extra setup to apply ?
thanks a lot for any experienced input; best
Find usefull documentation about how to configure Geoip2 for nginx ingress kubernetes deployment.
Example Nginx Configuration ConfigMap
You will find the expected ConfigMap name at the nginx controller container entrypoint or environment variables. Furthermore you can override this name, the way to do so will depend on your nginx installation/deployment method.
ConfiMap Nginx supported configurations
You will find there a listed all the supported configs/properties plus a sort description about them and how to use them.
For this specific question, the property to configure Geoip2 is "use-geoip2" (link below)
Enable GeoIP2
remark: you will need a license and add a flag at nginx entry command providing it
The nginx_http_geoip_module module creates variables with values depending on the client IP address, using the precompiled MaxMind databases.
This module is not built by default, it should be enabled with the --with-http_geoip_module configuration parameter.
The module analyze headers, next connect to defined database, fetch the localization information and offers a variables regarding to them like
country or city of connection origin. Some examples:
$geoip_country_code - two-letter country code
$geoip_city - city name
$geoip_postal_code - postal code
I'm a newbie in domain names, DNS etc.
I'm using surge.sh for deploying my app. Now I want to add a custom domain, that I registered using transIP, and I can't get it working. I set the IP address to 45.55.110.124, as they explain here. All together, I entered the following settings:
Name: *
TTL: 1 min
Type: A
Address: 45.55.110.124
And another one, exactly the same but then using name #:
Name: #
TTL: 1 min
Type: A
Address: 45.55.110.124
I created a test page that contains hello domain, inside a simple html file. Now, I deployed the page by moving to the folder that contains the html file and doing: surge ./ mydomain.io.
I waited over 5 minutes and nothing is changing.
Now, my questions are:
What am I doing wrong?
My domain provider suggests that I also use an IPv6 address, but which one should I use for Surge?
Why is there an option of setting TTL longer than 1 minute, who wants to wait longer before their deploy comes online?
For starters, you want to use the CNAME instead of A record if possible. The reason for this is that their IP address can possibly change out from under you when infrastructure changes / updates / re-deploys. If possible, remove the A records and create CNAME records pointing to na-west1.surge.sh. instead.
Next, assuming that they want you to point to the same IP as na-west1.surge.sh resolves to, that IP is different from the documentation (possible even due to my previous explanation). You can ping the domain or use the host utility to get the current IP address:
$ host na-west1.surge.sh
na-west1.surge.sh has address 138.197.235.123
Armed with this information, try changing to CNAME records first. If this isn't possible, then use the updated IP address that you get from resolving the their CNAME.
I am trying to use the ElasticSearch module (https://github.com/cleverage/play2-elasticsearch) with my Play 2 application. In the readme, it says I should add the following to my application.conf:
## define local mode or not
elasticsearch.local=false
## list clients
elasticsearch.client="192.168.0.46:9300"
# ex : elasticsearch.client="192.168.0.46:9300,192.168.0.47:9300"
What is local mode? What is my client URL supposed to be? I can not find any information on what these options should be. With my current options, I get a NoNodeAvailableException.
Some people suggest:
elasticsearch.local=false elasticsearch.client=mynode1:9200,mynode2:9200
But what is mynode1 and mynode2? It doesn't work with my application. Can anyone help? Thanks
What is local mode?
If elaticsearch.local=true, a elasticsearch node is started in your application ( embedded )
What is my client URL supposed to be?
It's your host:port, but the port is the tcp transport define on your elasticsearch node.
By default, the port start on 9300 ( http://www.elasticsearch.org/guide/reference/modules/transport.html )
I can not find any information on what these options should be. With my current options, I get a NoNodeAvailableException.
I think you have a problem on port number.
mynode1 and mynode2 are elasticsearch nodes.
Do you have any Elasticsearch node running?
On which IP address?
Can you try to connect on these nodes using curl, for example:
curl localhost:9200
Or
curl YOURIPADDRESS:9200
If one of this is successful, then configure your play app using YOURIPADDRESS:9300 as Nicolas Boire wrote before.
If no one is successful, check that you have installed Elasticsearch and launched it before.
HTH
I've just had the same problem, be sure that you respect the version requirements written in the table : https://github.com/cleverage/play2-elasticsearch
At the beginning, I set up the latest version of the plugin 0.8.1 but my ElasticSearch version was 1.0.2.
By starting ES with version 0.9.13, it worked.
I have an HAProxy install which was configured by someone who left the company. It runs on Ubuntu 10.04 and it seems to use 3 configuration files in the directory /etc/haproxy
haproxy.cfg
haproxy.http.cfg
haproxy.https.cfg
I don't see the point in using the haproxy.https.cfg file as I believe (in our configuration) it can all be configured from a single haproxy.http.cfg file but when I remove that httpS file it complains bitterly and refuses to run. My question
Is this the standard configuration haproxy uses or if not, I can't find a reference to the "S" file anywhere. Can anyone suggest how HAProxy concludes it should use it?
Thanks
The very answer to your question: your haproxy is simply launched with those three config files ( -f haproxy.cfg -f haproxy.http.cfg -f haproxy.https.cfg, maybe from /etc/init.d/haproxy but mileage varies depending on your distribution ).
If you remove the file, of course it will complain.
This is not particularly standard, but ain't bad either, it helps structuring the conf rather than having a very long file.
The task of the .https version will certainly be to redirect the https traffic towards a service that can handle HTTPS (stunnel or nginx usually), since haproxy cannot terminate ssl connections. (stunnel has to be patched, see on the haproxy page)
If you want you can merge those files into one or two, just find out how haproxy is launched (check for init.d or let us know which distribution) and fix it appropriately.
I believe that it is only /etc/haproxy/haproxy.cfg that is used by default.
This may be of use to you (1.4 configuration reference):
