Help! "They" want me to shut down my dial-ins unless I can make them "secure". Suggestions? I'm thinking of a few approaches, but I don't know what is commercially available. 1. Software to run on 4.3 BSD (Vax 750) or SunOS 4.0.1 (Sun 4) to implement call-back using the existing modems. 2. Black boxes to sit between the phone line and the modem and perform call-back or other verification. 3. Black boxes to sit between the modem and the cpu and perform call-back or other verification. 4. Terminal server with modems attached, where call-back or other security measures are implmented in the terminal server. Once the terminal server grants access, user would connect to a specific host, using telnet or rlogin. 5. Call-back modems. (Icky-poo. Makes upgrading to new modem technologies very difficult.) What do y'all think? -- David Schachter Daisy/Cadnetix Corp. (415) 960-6644 / ...!ucbvax!imagen!atari--\ david@daisy.uucp OR + ...!uunet-----------------!daisy!david \ ...!pyramid--------------/
