Ranked in these QuestionsQuestion Ranking
Pro De facto standard client for SSH, Telnet and Rlogin
Pro Source code available
Full source available. Compile and modify it yourself.
Pro Runs Pre-configured virtual machines
Allows you to run your virtual machines pre-configured by you or others.
Virtual Box versions for:
-- Windows 7/8/10
-- All Linux installations
-- MAC OS x
-- Solaris 10/11
Virtual OSs include:
-- Oracle Linux 5/6/7.x (RHEL clones)
-- Occassionally a Windows Beta
Oracle itself provides many free VMs, pre-configured with various software stacks and hands-on lab materials for learning, geared toward. These have helped me earn three of my Oracle certifications:
-- Oracle Database development
-- Oracle DBA
-- MySQL development
-- Java Standard/Enterprise development
-- Big data
-- Webcenter portal & others
Pre-installed software in or more of the various stacks includes:
-- Oracle Database 11/12
-- Enterprise Mgr
-- Cloudera, etc.
Pro Supports modern shells
Whether you prefer zsh, bash, or fish, Linux will support it.
Pro Isolated from Windows
VirtualBox provides almost total isolation from Windows running underneath it, removing a lot of security issues.
Pro Free / Libre Software
While the OS underneath it is proprietary and does spy on you or actively violate your freedom, so to speak, you can still have a little piece of mind knowing that VirtualBox (your Linux distro and shell of choice) as well as Terminator are all FOSS.
Con Lacks features
It is JUST an SSH client. There are many other options with built in X-servers, Multitabbing, etc.
Con Can not save passwords
Anyway, you can use "PuTTYgen" to generate a key pair, then use "Pageant" to do a password-less SSH remote login.
Con Tedious logging/tracing
Its tedious to set up logging and tracing (e.g. for serial connections).
Con No global settings
If you want to change a setting for all your connections, you'd have to do it individually.
Con No login scripting
Con Install a whole operating system for one program
You would need to install the entire Linux distribution just for one single program.
Con Slightly slower than just running Linux
The Windows + VirtualBox layer introduces some overhead that wouldn't be present if Linux were installed directly on the machine.
