trying a quick experiment with ACI to see if I can use it to host iperf3 for some on demand network performance testing. The docker image is https://hub.docker.com/r/netgio/iperf3server/
I can get the container up and running but when I try to connect to it the iperf client gives me the error "iperf3: error - control socket has closed unexpectedly"
I was hoping this would be a simple, single port, single instance use case. are there any specifics related to socket connectivity into ACI instances that would affect this?
EDIT:
iPerf3 defaults to TCP port 5201 so to ensure ACI port mappings are working as expected I created an nginx docker image configured to listen on port 5201 and deployed to ACI. This worked as expected (I could access the default home page at http://:5201). So the issue seems to be specific to whatever iPerf3 is doing with its sockets.
Note the error happens almost immediately at launch of the client iperf3 process.

I am very new for F5-LTM configuration.Any help related to below requirement will be vary much appreciated.
I have my application on Weblogic-11g server running on managed server at port number : 8001.
Now as my user count has increased i have created one more managed server at port number : 9001
Previously all my request were coming on http://ip_address:8001/login.html
now still i want all request should come from same but they redirect to both http://ip_address:8001/login.html and http://ip_address:9001/login.html
Note : i would also like to inform that in my application i have many other servlet also running so i want request forwarding based on http://ip_address:port_number/servlet
Any body who know How i can achieve my above request forwarding configuration in F5-LTM.
Thanks Again.

I don't think you need a different port and redirection.
You can still run the app on your second server on port 8001. Then you can add both the server under one virtual pool which will be under a virtual IP. Then the user can go to the app by using http://virtualIP:8001/login.html.
When a request is received by the virtual IP it can load balance the request between the two servers which are running the app on the same port 8001.
This is a good documentation in case are interested :

I am working on an angular app using the angular cli to set things up. Running the ng serve command spawns a server at this address <my_ec2_host_name>:4200. When I try to access the page on the browser it doesn't work (connection timed out error). I believe this is because of security reasons so I added the following rule to my security groups for the ec2 instance:
Port 4200 should now be accessible but I still can't get the page to load. Can someone think of how to get this to work?
Start angular with below command.
ng serve --host=0.0.0.0 --disable-host-check
it will disable host check and allow to access with IP
You can set up the host option like this:
ng serve -host 0.0.0.0
The steps you are doing are correct for opening a port via Security Groups in the EC2 console. Make sure you are modifying the correct security group, and make sure that your changes have been saved.
Your container may have additional firewalls in place, so you will want to check the OS documentation. For Example, RHEL uses iptables as a further security measure: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Security_Guide/sect-Security_Guide-IPTables.html.
That looks correct. Are you sure that your server is running and listening for connections?
You should ssh to that server and verify that the page can be loaded locally. Eg:
curl http://<YOUR HOST IP ADDRESS>:4200
eg: curl http://54.164.10.123:4200
You should be careful to use the public ip address (eg: IPv4 Public IP when you're in the EC2 console). I've run into problems in the past where I've got a server listening on one IP address (often localhost) and not the public ip address.
Also maybe a problem: Is your host inside a VPC of some sort?
It's easy to change the port of the application using the launcher. Go to Edit>>Application Settings (or alternatively Ctrl+i) and change the port. Since I was getting an error similar to the one given below, I changed the application port from 8080 to 48080. Unfortunately, I am not able to change the admin port from 8000 to 48000, because of which I am getting the following error.
google.appengine.tools.devappserver2.wsgi_server.BindError: Unable to bind localhost:8000
I also tried the method illustrated in the following image (my reference being this link):
Regardless of what I try, my web-browsers (Chrome and Firefox) return a message similar to This webpage is not available. Any ideas are appreciated.
I have seen this before, when I had a crashed instance running on the port. You may have a frozen Python script running on that port. On a Mac, I can go to Activity Monitor and kill the process. Not sure if you can do that via task manager in Windows. You may need to restart machine.
My WCF Service is hosted under net.tcpbinding and in case it is not running when client makes a call to its methods but let me tell you our some of clients get access and some of not. i even check antivirus setting and firewall setting for each client but haven't came up with right answer , client gets the EndpointNotFoundException with this message:
There was no endpoint listening...
i have check the path of service there is no mistake in path. and in my nettcp service based on window credential type and enabletcpportsharing is also on.
Still searching for right solution.
Thank you!
After trying telnet (IP Address of app server) Port. so i can understand it's blocking by window firewall or router firewall. if telnet open window from client machine that's mean its working and if not opening in window then call Network administrator to open that port
Eg. telnet xxx.xx.xx.xx 80 in command prompt
I need one server to receive ip requests from clients(there are not in the same intranet), and I can
route all the response packets to a special gateway server, and then I send the response packages to
clients after some processing. it is like VPN, but I want to do some development based one
opensource project, so i can control it myself.
any suggestion? thanks!
There is OpenVPN which is as the name already suggests open source.
You could set up the server on the local one as a kind of proxy (or reverse-proxy depending on your viewpoint) and have the clients connect to it.
It depends what protocol you're using, maybe it has explicit proxy capability or you can get an existing proxy program, or just proxy it using a simple socket forwarder program.
