It sounds to me that the security threat is in your file server (or whatever) software that transmits clear-text passwords over the net rather than encrypted ones. AppleShare encrypts passwords before transmitting them, so using it should be more secure than using other file server software. As for passwords typed when logging into to other computers (like UNIX boxes), I don't know. Either that or wait until someone solves this problem at the OS level (like with Kerberos or something.) Good operating systems do things in such ways that people who listen to the network can't find out passwords and other confidential information. Watch isn't the only program that lets people see what goes over the network. It's just easier to use and easier to get. -greg +----------------------------------------------------+ Greg Brail Internet: gjb@cs.brown.edu BITNET: gjb@browncs.bitnet UUCP: ..uunet!brunix!gjb Home: (401)273-1172
