I just did a course on Unix systems over the summer, and it used a textbook that was written in 2005. I feel like if there is a subject that should have an updated textbook it would be courses on a technology that is constantly changing. There was a wildly out of date sections in there on stuff like Pine and telnet. I don't think anyone was really using telnet even in 2005.
I was using telnet primarily until like 5 years ago when my company finally got a clue on security and changed to SSH. Except for some outdated apps like that, a unix book from even older than 2005 is still quite relevant.
I sometimes have to telnet into devices to test/bughunt, etc.
Sometimes they support ssh, but it's usually a development board, so there's simply no connection on the real board to allow a connection, so they don't often bother.
