Who Still Uses Telnet, Anyway?

Telnet is an old network protocol that most savvy organizations eschew in favor of the more secure SSH protocol. The problem is that early versions of Solaris 10 that Sun shipped had the telnet service automatically enabled, while more recent versions of Solaris 10 and the beta version of Solaris 11 have shipped with the telnet service disabled. While earlier versions of Solaris 10 shipped with telnet enabled by default, most systems administrators intentionally configure their systems to their own specifications, Castronovo explained. Consequently, Sun isn’t sure how many installations of Solaris 10 are running with the telnet service enabled, but he suspects that most customers would have disabled it anyway.
