If your school or organisation uses web filtering/blocking, it may be a good idea to manually whitelist the domains PiNet needs to access to install and build the Raspbian chroot.
If you are unable to whitelist these domains, consider doing the initial installation on an unfiltered internet connection. It is recommended that you connect your PiNet server to an internet connection with access to these domains at least once every 3 months for updates.
We have a simple testing tool that you can use before installing PiNet to check if any of the sites required are inaccessible.
To use it, open a terminal (on a computer running Linux, with Python 3 installed) and enter
wget https://secure.pinet.org.uk/downloads/checkInternet.py && python3 checkInternet.py
You should see an output similar to the screenshot below. If any of the sites show false beside them, then that may be an issue, especially the Critical and Highly Recommended sites.
Many schools and organisations use proxies to route the web traffic through a filter. Although proxies are not officially supported with PiNet, it is easy to manually add them to Raspbian and Ubuntu.
In Ubuntu, search for
proxy and select
Then enter your network settings and click
Apply system wide.
Adding proxy settings into Raspbian is a little more complicated. Make sure to read over the Editing outside guide as it includes a little more information about directly editing the Raspbian chroot.
sudo ltsp-chroot --arch armhfto enter the Raspbian chroot.
nano /etc/apt/apt.conf.d/10proxyto create a text file there and open it with the nano text editor.
Acquire::http::Proxy "http://username:[email protected]_server_address:port";where you have changed the details, for example
Acquire::http::Proxy "http://username:[email protected]:8080";
Some applications ignore this and for those, you may need to search the web for an answer.
