Re: PoE HAT - USB Ports not working - over-current

I initially tested both of my PoE hats with a USB hard drive with two USB connectors for adequate power and didn't have any issues. Today I brought one into work and tried to power it over PoE and had it actually throw over-current errors with just a keyboard and mouse in the two ports beside the NI...

Re: subdomains

Another good alternative for providing better security and that is light on system resources is HAProxy. If you're running multiple web servers behind it, you only need to expose it and it will provide a reverse proxy. The nice part of it is if you're using SSL/TLS you can update it without affectin...

Re: Raspberry Pi and Webservers

Have you looked at learning to use Ansible? It allows you to create scripts (called "playbooks" in Ansible lingo) that will repeat the script on however many machines you need to update. It connects via SSH and SFTP to the stations you are managing-both of which are what you should be using in a hea...

Re: i'm about ready to throw in the towel

A standard 104 key US layout keyboard features those characters on a dedicated button below the backspace. Every full-sized keyboard I've owned had them. The pipe ( | ) is heavily used in PowerShell on Windows and forward slash ( \ ) is critical to file paths in Windows-so I'm not sure why a manufac...

Re: Docker on Arch Linux

Aaaaand the cliche response fixed it. I rebooted it and then 443 started working.

Go figure.

Thanks for your help!

Re: Docker on Arch Linux

I don't think so? IPtables has nothing in it but docker exceptions and I don't see anything about a default firewall in the Arch documentation... It's really odd.

Re: Docker on Arch Linux

I used -p 80:80 -p 443:443 so it is bound to 0.0.0.0 for both. Port 80 does redirect to 443-but 443 says I can't route to it.

Thanks!

Re: Docker on Arch Linux

I installed netstat and confirmed docker was the only thing on port 443. Using curl, I can connect to 443 on 127.0.0.1 and on the container IP. It's like something else on the system is blocking it-but I've only installed VIM and Docker on this Pi prior to installing net-tools. Installing HAProxy I ...

Docker on Arch Linux

Hi All, My first question post! I've got Docker running on Arch Linux on 2 of my Pi 2Bs. I'm trying to set up HAProxy on one Pi from within a Docker Container with ports 80 and 443 on it. The issue: If I let Docker set the ports (which are non-standard when it does) everything works beautifully, but...

Re: Setting up a Web Server to host multiple Web sites

This may be a little late... But specifically you will want to look at setting up virtual hosts for each student's website if using Nginx or Apache (this gives you the separation of the URLs used so the web server can tell which URL that is sent to it should be served which website) and either local...
