- I have installed on my 386bsd machine a package called wrapper. From the
- Readme:
-
- --o--
-
- This package provides a couple of tiny programs that monitor incoming
- requests for IP services such as TFTP, EXEC, FTP, RSH, TELNET, RLOGIN,
- FINGER, SYSTAT, and many others.
-
- Optional features are: access control based on pattern matching; remote
- username lookup using the RFC 931 protocol; protection against rsh and
- rlogin attacks from hosts that pretend to have someone elses name.

- I have placed a copy of wrapper.tar.Z on anonymous ftp at oes.orst.edu in
- /pub/386bsd/wrapper.tar.Z. There are many other sites for this software
- as well.
