Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

By using VX ConnectBot (which, unlike other versions of ConnectBot, allows special linux characters, such as % $ *; also I generated the public keys with Irssi ConnectBot) I can connect my new android tablet to my amd64 debian servers. Tablet and my servers are at a Zyxel router, identified as indicate with commands below; I have no domain, simple ADSL, that is, my "servers", no matter how big, should be better identified as workstations). However, although VX CB should also allow scp file transfer, I am unable to get that.
ssh Connection is obtained as follows:
ssh firstname.lastname@example.org (where 36 is one of my servers)
scp filename 192.168.1.33:/ (where 33 is my tablet)
ssh connect to host 192.168.1.33 port 22: Connection refused
scp -P 2211 filename 192.168.1.33:/
ssh connect to host 192.168.1.33 port 2211: Connection refused
I did not manage to get root privilege with android (I am not interested other than in file transfer between my tablet, my servers, and the mainframes at the supercomputer center, as a low-cost connection)
I can also connect to the supercomputer center, launch jobs, etc, however unable to get scp working for unspecified reasons.
Working with VX ConnectBot and the supercomputer it seems that the problem is permission on the android side
scp user@host:myfile /Download (which is a folder used by android to download from the web with kindle or other app)
/Download: Permission denied (same issue wherever I tried on the tablet)
Should permissions be changed for the tablet folder? If so, does it require root privilege, how? That means that I have no interest in android except downloading and uploading with my servers and the supercomputer.
Permission under Android can be a bit tricky. basically i isn't expecting you to access these things outside of apps - which are strictly controlled in their accesss to file systems.
If you have an SD card (aka TF card) try copying to that instead. My cheapo Chinese Android tablet has limited internal storage so I regularly copy to the external SD card - although I don't bother with scp for it.
Incidentally, did you come across a (free) app called Terminal IDE? Gives you a bash-like shell, vi etc (courtesy of busybox) and allows you to telnet into your tablet over wifi
