Here's a version of the encrypted telnet/ftp package. Read comp.security.unix for more details. -- Nathan Lawson | "One of the advantages of using UNIX to teach an operating CSL 490 Admin | systems course is the sources and documentation will easily 756-7180 @Work | fit into a students briefcase." -- John Lions (1976) --- Begin included message --- During the last days many people asked for an encrypted Telnet. After my first posting some people were interested in getting the sources. Therefore we put them on our FTP server. Here is the announcement: You can fetch the package and some related stuff via anonymous FTP >from our server at the following location: ftp://ftp.tu-chemnitz.de/pub/Local/informatik/sec_tel_ftp (Internet address: 134.109.2.13) Please read the file README first. This briefly explains what the individual files in this directory contain and gives you some hints how to install the package modified by us (tuc-if-sra.tgz). Please note: the package srasrc-1.3.tar.gz was the starting point for our modifications. It is incomplete. It's not necessary to fetch it unless you are interested in the Kerberos authentication extensions we deliberately omitted or if some of our changes should be inconvenient for you. =============================================================== Name : Holger Trapp Institution: Technical University of Chemnitz-Zwickau Faculty of Computer Science Chair of Computer Networks and Distributed Systems
