They are internal to my owner, er, employer, McKesson Corp; they are taught by ACC Learning Solutions. Took Linux Fundamentals last week. Scheduled Linux System Adminstration for next week if my boss will let me go. Might need to cancel, though. Have real work to do, though the Linux stuff is both useful and relevant to my current job.
YOu should try to get them to send you for RHCT/E training..
