ssh-base

This is the base image of ssh server, bundled with systemd.

By default, UsePAM and PasswordAuthentication are both set to no.

The Dockerfile contains an alternative way to setup sshd, which could leave UsePAM set to yes.

The following fixes are included:

1. /etc/pam.d/sshd fix

   pam_loginuid.so is set to optional, otherwise user will be kicked off after login.

2. /run/nologin removed

   Prevents ssh login from printing System is booting up. Unprivileged users are not permitted to log in yet. Please come back later. For technical details, see pam_nologin(8).

3. systemd-logind.service fix

   ProtectHostname is set to no. This fixes 25 second of hang up every login.
