I'm very new to Jupyter notebooks and recently setup a dev instance with a basic password for external access. While this works fine, I need to tie it into LDAP or PAM authentication on my RHEL server.
As I started reading about this, it appears JupyterHub is the way to go with but I'm running into some issues with that setup. I did some basic configuration and I can login fine via PAM, but it says "Spawn failed" after the login page.
Ideally I'd like to stick with just notebooks + LDAP auth if possible to make things simpler. If that is not possible, can anyone help me out with what type of configuration I need for hub to frontend notebooks and just forward to the existing setup I have?
Hub is currently running on :8000
Notebooks is currently running on :8888
I also have custom themes on Notebooks that I want to keep, even if I have to use Hub.
Any help would be greatly appreciated.
Instead of using Hub, I ended up just using Apache to front end the connection and then proxy to 127.0.0.1:8888 localhost.
This allowed me to utilize LDAP auth as well as the certificates that I'm already utilizing with Apache.

I have an old ASP.NET 4.6.1 app running in a VM on Azure.
I’m trying to create messages in an Azure Storage Queue and nothing is happening when I run it on production VM. However, on my dev machine, it works fine and I can create messages in the same queue that I’m trying to access from the production VM.
The call to the queue is within a try catch block and it’s not throwing any errors.
Another important point is that I had use the old/deprecated WindowsAzure.Storage NuGet package as that’s the one that seems to work on this ASP.NET MVC 4.6.1 app.
Any idea what could be the issue here? Because I don’t see any errors, I’m not sure how to go about fixing this problem.
According to MS Docs, one troubleshooting option you can try is "Redeploy Windows virtual machine to new Azure node"
The doc says,
If you have been facing difficulties troubleshooting Remote Desktop
(RDP) connection or application access to Windows-based Azure virtual
machine (VM), redeploying the VM may help.
Source: https://learn.microsoft.com/en-us/azure/virtual-machines/troubleshooting/redeploy-to-new-node-windows
See also additional troubleshooting steps:
Restart the virtual machine
Recreate the endpoint / firewall rules / network security group
(NSG) rules
Connect from different location, such as a different Azure virtual
network
Recreate the virtual machine
There are various reasons when you cannot start or connect to an application running on an Azure virtual machine (VM). Reasons include the application not running or listening on the expected ports, the listening port blocked, or networking rules not correctly passing traffic to the application.

This might be network Firewall issue. Open azure portal from production vm machine. You can even try to manually see the storage and upload files from web.
Is there a way to access the Meteor server logs on a production server? All I needs is something that records what I'd see as the server console output on my dev machine, in a log file on the server. I would have expected Meteor to log them somewhere by default but I can't find anything.
I'm running Meteor 1.6 on a Digital Ocean droplet, Ubuntu 16.04.3. Deployed with Phusion Passenger.
I've hunted around and there are a bunch of logging packages for Meteor but I can't figure how to use any of them; there don't seem to be any basic examples or instructions.
This must be a really common requirement - anybody know how to do this? Thanks!
Remember that Meteor runs on Node.js. Therefore, many things valid for Node.js is also valid for Meteor like location of the default root folder of the built-in web server. You should check the path "/var/www/html", first for the server logs.
I created a new app repository in Github, built on the Meteor platform. I am having significant difficulty deploying the app to my DigitalOcean droplet, however. I am trying to connect my Github repository to the droplet and to deploy that to my domain. I am trying to do this in SSH using puTTy; however, after setting up a root account and password, I am unable to log in through SSH. I receive the following error: disconnected: no supported authentication methods available (server sent:publickey)
Does anyone know why this error is coming up? I have looked through more tutorials for deploying a meteor app on digitalocean than I care to admit, but they all seem to take different approaches and many are outdated. Any advice would be greatly appreciated!
Thank you
I reckon the easiest way is to use meteor up. It's a very simple process, and you don't need to be continually sshing into your target server, with all the hassles involving ssh keys.
In my experience, once you have it set up, it's a very painless process, and you can deploy with a simple command each time.

It looks after the following:
Setting up your server with docker instances
Creating SSL certs using Let's encrypt
Building your app, bundling it, transferring it
Starting the app
Rolling back if it doesn't work
There is some trust involved, but it's worth it for a seamless deployment scenario
I have successfully installed Apigility to a remote CentOS server. It tell me to go to http://localhost:8888 to access the admin panel. This server does not have a GUI installed so I don't have the ability to remote in to use a web browser. Is there a workaround to access the Apigility interface remotely, possibly restricting access to my IP address? If not do I have to install it on my local machine and then deploy my work to the remote server?
You could add a .htaccess
file
to set a password on it
If you're deploying to AWS you should be able to configure your SecurityGroup to only allow request to your installation if you're trying to access it.
if you want to develop your application right now I would recommend to have a local installation in a docker container or so to perform your changes. If you're going live you shouldn't change anything in the admin surface either.
centOS server using terminal if i am right. The best way to do this with centOs server in terminal is to open port 8888 to the public and access the server from another system serverIP:8888 (using tools like firewalld in the centOs server. U will have to install firewalld) https://www.rootusers.com/how-to-open-a-port-in-centos-7-with-firewalld/
I have several domains on Digital Ocean hosting which runs behind Nginx server. I am using it mainly for python aps, but I would like to setup them with PHP as well.
Python apps run behind Gevent middleware. Now I need a control panel to make some upgrades via GUI such as :
- mail server installation and management
- web stats installation and management
- Wordpress/Magento installation and management
Please help me to chose control panel which is convenient for installation behind already running Nginx server. Thank you
I don't think that is something which will fulfill your expectation, and I'm pretty certain.
But closest to your needs seems to be Ajenti / Ajenti V control panel.
