Is it just me or is the telnet client no longer present in macOS High Sierra? There doesn't appear to be an open source drop in replacement that works out of the box, and telnet + libtelnet combination from opensource.apple.com doesn't appear to work out of the box either. I think the telnet package that gentoo uses could be patched to work, but wanted to see if anyone wanted to weigh in here first before I spend too much time on that.
