Where to start
Baby steps
Context of Terminology
Simple connection
Complex, multi-hop connection
Essential Terms
- local - local computer, computing device or computing system the user is initiating connection or is connecting from
- remote - remote computer, computing device or computing system the user is connecting to
- gateway - intermediary computer, computing device or computing system the user is using to connect from local system to remote system
- client - software client (program) the user is using on local system to connect to remote system
- server - software server (service, program) the user is connecting to on remote system
More Terms
- localhost - networking terminology where a computer system refers to itself with it
- local host != localhost :: for local host localhost means local host, for remote host localhost means remote host
Secure Shell
SSH? Wait, Secure Shell??
Yes, the ubiquitous three-letter acronym SSH means Secure Shell, the computer program one can use to securely connect to a remote host command line.
Secure Shell comes in a variety of looks and flavours, from a simple command line utility to bells'n'whistles packed graphical user interface.
To list a few:
- OpenSSH SSH client, the native Linux command line utility (CLU) OpenSSH
- Cygwin SSH client, the same as above but compiled for Windows and distributed as Cygwin subpackage Cygwin
- SSH Secure Shell, the ancient original SSH, now replaced by Tectia Tectia
- Putty, SSH functionality packaged into GUI for Windows with less bells and whistles Putty
- Bitvise SSH client, SSH that comes with GUI for Windows Bitvise
- Termius, iOS applet for iPhone & iPad
We'll be getting in touch with 3 of the above: native Linux CLU and Cygwin CLU for operating at a command line interface (CLI) and Bitvise SSH client for working under Windows when there is no Cygwin available.
Setting up passwordless access to remote host
Remote desktop client
Is host localhost local or remote, after or before gateway (and where do ports fit in)?
Depends on point of view
