Thanks again, Scott:
I am working through your suggestions.
> *1.* May I suggest on Ubuntu you edit ~/.ssh/config and add an entry like:-
I am using Ubuntu 12.04 LTS. But in my "~/.ssh/" directory is only the
text file "known_hosts". Its content appears to be encrypted.
> Replace $PhoneNickname with a nickname for your phone (e.g. p)
> Replace $FQDN with the fully qualified domain name of the phone (see /etc/hosts on Ubuntu for the name)
In my "/etc/" directory is a file called "hosts". It lists the IP
addresses of localhost and my PC and phone nicknames.
> Once that's done you can just use the nickname to ssh/scp etc.
Yes, I thus (by nickname) SSH into the phone.
> *2.* May I also suggest using a private key instead of insecure password logins?
I feel clueless (lacking confidence) on this subject. Please suggest a
beginner's on-line reference.
> If you have ssh always listening on port 22 *and* allow both root logins and password authentication you should at least configure port knocking or fail2ban to stop brute force attacks.
I feel ignorant here! So again I ask for referral to an introductory
on-line explanation!
> (but given that most people leave the PIN for their voice mail set to the default last 4 digits of their phone number I may have unrealistic expectations)
Long ago, people working on computers had doctoral degrees. Then
marketing expanded the number of machines beyond four!
> To check what port the phone uses run either of the following on the phone:-
> echo ${SSH_CLIENT##* }
The result was null.
> cat /etc/ssh/sshd_config | grep -v "^#" | grep -i ^"port "
I got a file not found error. So I looked in in the phone's "/etc/"
directory. But it didn't have an "ssh" subdirectory!
> *3.* If you find working in a single session frustrating may I suggest "screen"?
It's installed--though I don't know how to use it! Can you recommend a
tutorial?
> Add the following to ~/.bashrc
My default shell is fish.
> Lots of tutorials on screen at the Google University
I am wallowing in need-to-know!
