Comfort and peace, I wish you.
I provide a free Solaris 10 account. Terms and conditions of usage are in the message of the day, and on the website listed here. This account includes root access to Solaris 10. There is no charge. Further information is not unavailable at:
essentially, telnet to: trainingzone.getmyip.com
This may not be a bad way, to, understand Solaris and Linux equivalent commands.
