QUESTION

How to allow web applications from different Azure accounts (company) to allow mutual access over the Internet?

Asked 2022-Jan-24 at 02:59

I want my web app to be able to send requests to another web app, I have added the (Outbound) Public IP of the web apps to the mutual access restriction. In Kudu Console, I use "tcpping" to test that the hostname of his web app is connected (443port). But I execute my web app with postman and my web app is getting "Forbidden". Later, when I executed curl in the Kudu Console of my web app, I also received 403 Forbidden. And the Kudu Console of the other party's web app executes curl and displays 401, In addition to Access Restriction, do I need to confirm any settings?

“Error 403 - This web app is stopped.”, when browsing Azure website.

“HTTP 403 : IP forbidden“, states that the client IP browsing the App is not allowed to access that App service , “IP restrictions” have been explicitly configured on the App service. You can check the list of blocked IP addresses from the portal .

There are many reasons that can cause this error .

Check if the web app is running or stopped in the portal.
The site might have reached billing limit and your site has been disabled.
The Azure Website might have reached a resource quota limit , applies to either Free or Shared scale modes.

401 Error

Check if you have enabled Authentication / Authorization in the portal?
Enable Application Logging -> Filesystem to Verbose from the Diagnostic Logs blade. Navigate to D:/home/Logfiles/Application directory to find the logs generated .
These logs should provide you a verbose output of the authentication process and what is failing. You can access the logs using FTP or using kudu (yourappname.scm.azurewebsites.net/DebugConsole - replace yourappname with your app's name)

Please refer Authentication & Authorization for more details.

How do I get a multi-node Keycloak cluster running with docker containers (no k8/swarm/etc)?

Asked 2022-Jan-20 at 22:26

I have three EC2 instances in AWS:

It is most usually caused by the server not being able to run some process necessary to support your session.
Your SSH server, may not be able to access the server key files, due to an incorrect permissions.
Always try to connect with another SSH (FTP) client to find, if it is server or client related problem.
Verify the connectivity between your Azure Web App and the on-prem FTP server

Trying to use TCPPING for JGroups in a Infinispan env fail as address is Transport.getAddress() is null

Asked 2021-Sep-22 at 10:09

I am trying to setup a replicated Infinispan embedded cache.

When using the demo code for programatically setup the cache, everything works, as expected (https://github.com/infinispan/infinispan-simple-tutorials/tree/main/infinispan-embedded/cache-replicated)

Now, I want to configure it to use a defined list of initial hosts.

So, I changed slightly the code to be :

Your configuration is too minimalist :)

Infinispan requires JGroups Group Membership and Reliable Transmission to work properly.

Also, failure detection may be useful to have if you don't want to lose data on nodes crashing.

Hibernate with infinispan invalidation cache in a cluster

ANSWER

Answered 2020-Nov-06 at 09:08

The problem is using JCache - the table assumes InfinispanRegionFactory instead of JCacheRegionFactory.

It seems that Infinispan does not have a module to support Hibernate 5.4 explicitly - I would guess that modules to support Hibernate 5.3 should work even with Hibernate 5.4, though, since there hasn't been much changes in the second-level-cache land in Hibernate 5.4.

I am surprised that 2LC works with JCache at all with replicated/distributed caches - I would be pretty sure that it does not work 'reliably' (transactionally, covering edge cases etc.) anyway.

SQL Azure database connection issue

My problem is, I am getting below error when I try to connect the SQL Azure database by using SQL authentication from the Azure VM. The problem is interesting because I can connect same database from different Azure VM. SQL Server has a firewall and both VM IP addresses are whitelisted. I tried to make tcpping to SQL destination from both VM works fine. Unfortunately, I don't have access to grab the azure diagnostic log from the destination SQL Server.

Congratulations that you resolved the issue:

"Yes, I was able to resolve the issue by moving VM to another vnet. It was using private IP even though it has public IP, I believe because of subnet service endpoint configuration"

As a result, when I put the machines under an ELB, the login doesn't work. I have tried TCP and UDP for IP casting. Tried using TCPPING instead of MPING (although not sure whether I used them correctly). Infinispan is being used for distributed caching. Here is the default configuration, followed by the changes I had made:

Answered 2020-Jul-13 at 12:36

This is how I debugged it:

Make sure that jgroups-tcp and jgroups-tcp-fd is listening to public interface, and not private interface. These properties are in standalone/configurations/standalone-ha.xml.
While starting the the instances of your cluster via bin/standalone.sh | bin/standalone.bat make sure you pass -b and not 0.0.0.0 (all interfaces). To find the public interface IP, run the following command:

ifconfig eth0 | grep -i mask | awk '{print $2}'| cut -f2 -d:
When you start the first instance (should be the instance you passed in initial_hosts property; you can try telnet 7600 to test if your TCPPING is working or not. It should work for cluster discovery.

Current transaction was aborted (probably due to a timeout, but maybe as a consequence of delivery failure). You need to rollback current transaction and start new.

However let me note that 5.3 was released 2013/06/26 - you're using almost 7 years old version. If there is a bug, no-one will even try to check it out.
