#FAQ

Why can't I SSH in as root?

By default Photon does not permit root login to ssh. To make yourself login as root using SSH set PermitRootLogin yes in /etc/ssh/sshd_config, and restart the sshd deamon.

Why is netstat not working?

netstat is deprecated, ss or ip (part of iproute2) should be used instead.

This Guide guide depicts the most common examples.

Assuming you have the Ubuntu development environment setup and got the latest code pull into /workspace. Lets assume your package name is foo with version 1.0.

I just booted into a freshly installed Photon, why is docker ps not working?

Make sure the docker daemon is running, which by design is not started at boot time.

What is the difference between the Micro/Minimal/Full installations of Photon?

Micro is the smallest version of Photon, under 220MB (as of 03/30) to be used as base for customization.

Minimal is Micro plus Docker and Cloud-init packages.

Full contains all the packages shipped with ISO.

What packages are included in Minimal?

See packages_minimal.json for Minimal packages.

Why is vi/vim not working in a Minimal installation of Photon?

We have nano installed by default for file editing in Minimal. Use tdnf to install vim.

We are working on supporting some standard options. Currently we recommend using sshfs for file sharing between hosts and Photon.
