Is Just-in-time (JIT) VM access under Fortigate Firewall is available in Azure

I was going through this article : Just-in-time (JIT) VM access for Azure Firewall is now generally available and Understanding just-in-time (JIT) VM access
My questions are :
Is Just-in-time (JIT) VM access using Key Vault for Fortigate Firewall is available in Azure? - Nothing found from search. If its available, how to implement that? So that, users can access VMs behind the firewall.
Thanks
It is not available for FortiGate firewall.
You can find the available options here https://learn.microsoft.com/en-us/azure/security-center/just-in-time-access-usage?tabs=jit-config-asc%2Cjit-request-asc

Running infinispan in docker on windows 10

I am trying to run the infinispan docker image on a Windows 10 machine with docker desktop for windows.
I wrote a small test Java program that connects to localhost:11222 using hotrod and accesses a cache.
The problem is that after the initial connect the client receives from the server a new address 172.17.0.3:11222 and it fails connecting to this address because this is a docker internal one and
docker desktop for windows cannot route messages directly to an internal container address.
Is there any workaround available in infinispan or on the windows machine ?
The simplest solution is to disable the handling of topology updates in your Hot Rod client:
infinispan.client.hotrod.client_intelligence=BASIC
More information about client intelligence here.
Note that this is not recommended in production: the client will ignore new servers coming up and it will keep trying to contact the servers in the initial server list long after they stop.

Jenkins ssh why it shows this error com.jcraft.jsch.JSchException: channel is not opened?

I know I posted a question that was bogging me for days but found a solution for it just 5 minutes after posting so I am posting about this problem that I get ever since 2 hours, anyway, I have a job in Jenkins that executes a series of commands remotely via SSH but before there is a connection establishment it throws me this error: com.jcraft.jsch.JSchException: channel is not opened, on my topology I have the Jenkins server in my main pc and I want to communicate with a CentOS 7 VM, on my jenkins I have configured everything (the SSH agent on global configuration for example), on my CentOS 7 VM I don't think that there's a need to open the port 22, my expected results are obviously the possibility to execute the script (let's begin by connecting), my VM has the ip of 192.168.127.129, if you want another information you can ask me by commenting, thanks in advance
I did not resolve the problem, however my VM was in host only connection, I changed it to NAT and problem solved but it isn't a permanent one nor best practice, now my VM is connected to the internet and is exposed to all of its dangers

gRPC Name Resolution Failure

While trying to run tensorflow-serving with docker, I am getting the following error issuing a client request using gRPC with following code:
`python client.py --server=172.17.0.2/16:9000 --image=./test_images/image2.jpg
debug_error_string = "{"created":"#1551888435.208113000","description":"Failed to create subchannel","file":"src/core/ext/filters/client_channel/client_channel.cc","file_line":2267,"referenced_errors":[{"created":"#1551888435.208109000","description":"Name resolution failure","file":"src/core/ext/filters/client_channel/request_routing.cc","file_line":165,"grpc_status":14}]}"`
Information about my environment:
OS: macOS virtual env.: Anaconda 3 Python 3.6 gRPC/tools 1.19
Would you please help me in resolving the issue?
This happens when the channel is in TRANSIENT_FAILURE and the load balancing policy can't find any ready backend to send the request.
Please file an issue on https://github.com/grpc/grpc/ detailing what you did, hopefully with more log/tracing context, so that we can better help you.
The IP Address, 172.17.0.2/16, which looks slightly different seems to cause the problem. You can use localhost instead.
So, the command for running the client.py can be
python client.py --server=localhost:9000 --image=./test_images/image2.jpg

Delphi - Firebird - Vista access to socket denied

I am facing problem with my delphi application connecting to firebird database on Port 45000:
If I try to connect as Localhost/45000:C:\DBNAME.fdb its giving below error
Can't format message 13:98 -- message file C:\firebird.msg not found. Unable to complete network request to host "localhost". Failed to establish a connection. An attempt was made to access a socket in a way forbidden by its access permissions.
I don't understand what is this error tried changing port cheked free ports using netstat command no use.
Any help will be highly appreciated
Thanks in Advance
I think I had the same problem in the past.
Re-installing Firebird helped.
Issue Sorted out.
Thanks to those who gave some suggestions.
It was Windows One Care firewall service which was blocking all the ports in the vista system.
I could not find it because it was visible only in the services and not anywhere else.
Read the entire Configuring Firebird. Create an alias of your database.
Also take a look on the Installing Notes. Add exception to the windows firewall. If still encountering problems take a look on the http://www.gradiencesupport.com/entries/20932048-Gradience-Pro-Enterprise-Unable-to-connect-to-your-Interbase-Firebird-Server
