Jenkins does not save any configuration when I make changes and click on "Save". I loaded the page on Firefox with Firebug, and I see that my postBacks are being aborted. I tried it on Chrome, and I get a "No data received". What am I doing wrong?
I installed Jenkins on an EC2 instance, and configured it to listen on port 8888. I opened the port on the EC2 console, as well as in iptables.
I then installed Apache2 and used it to provide a Proxy on port 9001, and opened that port as well, both in the EC2 inbound rules and in iptables. (When the setup starts to work, I'll close one of these ports.)
Jenkins is accessible through both ports.
Edit: I've also tried disabling iptables, the problem persists.
Edit: I've realized that the problem is with accessing Jenkins from outside. I logged in via SSH and accessed the site using elinks, and everything worked fine. However, elinks, being a text-browser, is a pain to use, and not all of the site is really usable this way.
After trying for several hours, I decided to try doing this on a different internet provider. Voila, things started working. I assume this is a problem with my Internet Service Provider, as this works perfectly on my work network.

I want to make my phone a Linux web server, by using the userLand application which gives you the ability to use ubuntu distribution on Andriod.
I already installed Django and ran my server on port 8080 since port 80 is busy (seems logical that android is using it)
and everything is good, it works when I try to access the website from another device on the local network.
so I proceeded to the next step which is making the website accessible from all over the internet then I found that you need to make a port forwarding on the router to allow devices from outside the local network to access a device in the localnetwork .
I followed the following steps :
made the phone's IP static locally
added the configuration needed for the port forwarding (phone's ip, port 8080, etc... )
found the public IP for my phone and used it and with port 8080
it is still not working:
I can access the website locally but can't access it through the internet.
I tried another method by using an already working server from the "AWebServer" application on google play
but still the same problem.
I tried temporarily to disable the firewall on the router but still the same problem
and finally, I tried to open the port on my laptop with OS: Windows 10
instead of the phone OS: Android, and checked with port checker but the port is closed and still the same problem.
I have been trying to solve this for a whole day)), I would be very happy if someone helped me.
thanks

Your ISP might have put you under a NAT, in that case port forwarding might still not work.
Your best bet is to use some sort of SSH Tunnels.
You can try with ngrok.
This will give you a URL to access your application from public internet.
Only caveat here is that ngrok is not free. They have a subscription based model. In the free tier, you can use ngrok but the link url changes after few hours.
If you want to, you can also implement something like ngrok for yourself. Read about ssh tunneling more. This will help you.
Apologies if this isn't the right place to post this question but I have a Jenkins container running on an ec2. Both listen on 8080. I have an NLB that listens on 443. When I log into to my https://jenkins.xyz.com, it redirects to http://jenkins.xyz.com. I get an error as nothing is listening on 80. If I manually change http to https after logging in, I'm in and just it works fine, although I get "reverse proxy is broken" error in Configure Jenkins. Tried a different container but still the same issue. Any help will be greatly appreciated.
Was able to solve my issue following the instructions in this article:
http://code.haleby.se/2016/01/22/enable-ssl-in-jenkins-in-docker/
Just had to give the jenkins user (UID) permissions to the directory containing the cert on the host (which I didn't see in the article but might be mentioned).
I have a test server that I can ping successfully although I'm not able to see a hello world test page I've created and mapped in IIS. I've also created an Inbound rule in the windows firewall. Is there something else I'm missing? I'm browsing http://x.x.x.x:888
Any advice greatly appreciated.
Many thanks,
Update
This is a AWS server
Have tried telnet from a client machine but I get Operation timed out
Nothing in IIS logs (C:\inetpub\logs\LogFiles\xxx)
Port 888 is what I assign the test website to in IIS
Have also moved the test file (index.htm) into the default website within IIS and tried browsing http://x.x.x.x:80/index.htm but I get This site can’t be reached
browsing http://localhost on the server displays the 'hello' message test page.
In windows explorer I've gone to the security settings by right clicking on the website folder and allowing 'everyone' read access
Firewall screen shot
Important update
the IP http://x.x.x.x:888 is the public IP within AWS for the server, not the interal IP of that actual server
On windows 10, I found a firewall issue for my testing server, this worked for me: go to Windows Firewall -> Advanced Settings -> Windows Firewall properties and set a public profile to allow incoming connections.
I'm trying to create a web app on AWS and I'm running into port issues. I would like to have multiple apps providing different services on different ports. I've created a website (on the same instance) to receive a text query and pass it to my app on port 3000. The app listening on 3000 is written in CherryPy.
We are using a VPN to provide security for the AWS instance. When logged into the VPN, everything works fine. The web page loads, the query returns the correct data. When I disconnect from the VPN, or someone else goes to the page, the page still loads, but queries to the service time out.
I've used netstat to make sure the service is listening but I'm not sure what could be blocking traffic. I've worked through the CORS issues as evident by the fact it works when I'm signed into the VPN.
What can I check now?
When I disconnect from the VPN, or someone else goes to the page, the page still loads, but queries to the service time out.
My assumption is that the web server and the app are on the same server.
It sounds very much like the connection from web server to app is happening via a routed IP address rather than localhost. In addition to being slower, it's also hitting your firewall rules.
Configure the web server to access your app on localhost:3000 and the issue should clear up.
I actually got it working. I have an AWS instance with nginix and CherryPy. When the user goes to a web address, the nginix page loads with a form for a query string. When they submit a string, the string is POSTed to a CherryPy service running on port 3000. The CherryPy service does some computations and returns a result via JSON.
I thought I had opened up everything completely for testing, but I was having so many issues. It turned out that having CherryPy set
"Access-Control-Allow-Origin" = "*"
wasn't working, instead I needed to specifically set the origin of the calling page.
CFHTTP on my new CF 9 server is failing. I get back "408 Request Time-out" when attempting to connect to the test page on the server via its internal or external IP. I am not using SSL and using the standard port 80.
My old CF 9 server can connect to itself fine but it also fails if attempting to connect to the new server.
If I RDP into the server, I am able to pull up the same test page via a web browser or via telnet to that ip port 80.
I suspect that this is a firewall issue. I'd like to know how CF makes an HTTP request under the hood before I talk to the hosting team. What service is making the call? What port is it running under, etc.
You don't say what operating system you are running under, but if it is Windows, I'd take a look at the Windows Firewall settings on your new machine, and disable the firewall. That will allow you to check if indeed it is the Firewall in the way.
If that works you can then try and add a firewall exception for the application, i.e. JRun.
Hope that helps.
