I'm not really sure how effective a encrypted telnet would be without kerberos... The key to the encrpytion would have to be passed in plaintext which kinda defeats the purpose... > Path: agate!overload.lbl.gov!lll-winken.llnl.gov!uwm.edu!vixen.cso.uiuc.edu!howland.reston.ans.net!news.sprintlink.net!matlock.mindspring.com!rsanders > From: rsanders@interbev.mindspring.com (Robert Sanders) > Newsgroups: comp.unix.bsd.freebsd.misc > Subject: Secure (encrypted) telnet > Date: 20 Apr 1995 13:36:41 GMT > Organization: MindSpring Enterprises, Inc. > Lines: 26 > Message-ID: <3n5o19$h32@nntp4.mindspring.com> > NNTP-Posting-Host: interbev.mindspring.com > > We're about to install a FreeBSD machine for network monitoring, so keep > in mind that although I am not yet a FreeBSD user, it's only a matter of > days. > > I've been trying to get FreeBSD's telnet (telnet, libtelnet, telnetd) to > compile with encryption and authentication enabled.
