Termux use of experience: Termux installed on android phone can set up a simple Linux server, but function more restrictive, and the real SSH server is quite different; In addition, Termux basis installed Ubuntu, the need to log Termux every time a user runs Ubuntu startup script, also cut version of Ubuntu, and not be able to run multi-user like a real person as Ubuntu server.
