I am trying to set up an internal Jenkins server for our QA team and facing some issues with the server URL. This is inside a corporate network and all sort of firewall and proxy settings are in place, however we need to access the server only with in our internal network. This server runs from a Mac Mini. I was able to install and access the server without any issues using localhost:8080.
I tried to set a custom URL (something like testjenkins.local:8080)under the Manage Jenkins option and never was able to access the server. The only option worked for me is with the IP address (IP:8080). I was able to access the server from other machines in the network using this URL.
The real problem with the above setup is that the machine IP changes(I am not able to make it static), and hence wont be able to get an always working URL.
Highly appreciate if any one guide me in the wright direction.
Given you have a dynamic IP on your server, a good alternative would be using ngrok. Ngrok can expose the port 8080 of that server to the internet via secure tunnels, and you can access it via an URL, so changes in the IP won't affect it.
However, ngrok exposes the server to the whole Internet. To make it accessible only for your team you can add authentication in both ngrok tunnel and Jenkins server (would it work for you?).

I've created a service inside minikube (expressjs API) running on my local machine,
so when I launch the service using minikube service wedeliverapi --url I can access it from my browser with localhost:port/api
But I also want to access that service from another device so I can use my API from a flutter mobile application. How can I achieve this goal?
Due to small amount of information and to clarify everything- I am posting a general Community wiki answer.
The solution to solve this problem was to use reverse proxy server. In this documentation is definiton what exactly is reverse proxy server .
A proxy server is a go‑between or intermediary server that forwards requests for content from multiple clients to different servers across the Internet. A reverse proxy server is a type of proxy server that typically sits behind the firewall in a private network and directs client requests to the appropriate backend server. A reverse proxy provides an additional level of abstraction and control to ensure the smooth flow of network traffic between clients and servers
Common uses for a reverse proxy server include:
Load balancing
Web acceleration
Security and anonymity
This is the guide where one can find basic configuration of a proxy server.

I'm trying to create a Test automation Pipeline to run my selenium scripts, I installed Jenkins in windows Remote Server 2012. Used following cmd($ java -jar jenkins.war) to start jenkins. It is working fine in Remote server with url:http://localhost:8080/
But when I'm trying to access it outside Remote server(my local machine) it is not working. am getting error message "This site can’t be reached"
My local laptop and Remote server is under the same proxy org network.
Can someone help how to resolve this issue , so that other folks can access it and run jobs when required from their laptops
Thanks in advance
Access Windows Firewall.
Add an inbound rule to allow port 8080 and
try accessing the url from any machine in the network.
you could allow/restrict access to all IPs, range of IPs or allow all. But to nullify the issue and confirm if its an issue with whitelisting IPs, I'd first allow access from all IPs with the wildcard *
for Debugging if its a port whitelisting issue, you could also telnet from the machine that you are trying to access this machine -
try
telnet remote machines IP Port
note: do not use a colon for port input just use a space
I have ssh'd into my rasberry pi and built a rails application.
Now how do I load the rails app from another machine?
I have tried IP:port in a web browser, but this fails.
Can I use ssh from a web browser to load the rails server process?
Are there gems I need to install to do this?
Is there any good documentation that I have missed?
SOLUTION
use ngrok to tunnel https://medium.com/#karimbutt/using-ngrok-to-create-a-publicly-accessible-web-facing-raspberry-pi-server-35deef8c816a#.sraso7zar
Maybe the problem is with the IP address you're trying to use. Servers don't necessarily forward their public IP traffic to localhost automatically.
Perhaps you could configure the IP address somehow, I don't know (others might?). Alternatively, you have a use a "local tunnel" service like ngrok or localtunnel. What these do is create a public URL for your localhost (i.e. your "loopback" address), so anyone can access it.
I spoke with a Ngrok author via email. He ensured me that I shouldn't need to expect any downtime from the service or to have to manually restart it. Although keep in mind that if you're on the free plan, whenever you restart Ngrok you're going to get a different URL. He also described it as kind of like a "souped up SSH -R"
I am running standalone neo4j database server at localhost:7474 on a linode instance.
Is there any way to view this in the browser?
If you have SSH access to the Linode instance then you can run ssh -L 7474:localhost:7474 youruser#123.123.123.123 which will tunnel the remote port 7474 to localhost 7474. In your browser you can now use http://localhost:7474 to see the remote server without opening anything to the world.
You want what's called a "reverse proxy". Outside of your box, you can't talk about localhost:7474 as a hostname. So you want an external facing web server that "proxies" requests and sends them to localhost:7474.
One such option is Apache mod_proxy used as a reverse proxy. Examples on how to use it are behind the link. In general it's going to boil down to a configuration directive that looks something like:
ProxyPassReverse /neo4j http://localhost:7474
You also really want to read the documentation on securing the neo4j server.
WARNING - neo4j's web interface will let you do just about anything without authentication, including delete all of your data, change it, put new data in, and so on. It is a very bad idea to expose that functionality to the entire internet. So if you use a reverse proxy as suggested above, make sure you add some authentication layer (again you can do this with apache and mod_proxy) to permit just any random person from connecting to your instance and optionally deciding to trash it.
working under linux server Centos remotly in local network, my rails server working there too. How can I enable remote web access? And if so how can I enable only couple of ip addresses for web access?
You should check on which addresses the server applications binds. If it has no external IP-Address then it wont be possible to access it directly from the internet. Then it is possible to use port forwarding to forward your application over your router. If you havent any access to the router you should ask the administrator of your network to forward it for you.
Another possibility is to plug a VLAN to a secound interface but you should think about security when you have a server that is connected to your NATed network and the internet directly!
if its only rails production server setup then you can try with this:
http://www.leonardteo.com/2012/11/install-ruby-on-rails-on-ubuntu-server/
it uses https://github.com/ballistiq/ruby-passenger-nginx-installer and they are maintaining the installer. I found its very helpful. it works like no-pain
