-
- This package provides a couple of tiny programs that log all requests
- to connection-oriented tcp/ip services (examples: FINGER, SYSTAT, FTP,
- TELNET, RLOGIN, RSH, EXEC), with optional access control on the basis
- of host (or domain) names, internet addresses (or network numbers) and
- daemon process names.
-
- The programs are nothing but small front ends. By default, they just
- log the remote host name and then invoke the real daemon. The programs
- should not require any changes to existing software or configuration
- files.
-
- Connections are reported through the syslog(3) facility. Each record
- contains a time stamp, the remote host name and the name of the service
- requested. Such information can be useful to detect break-in attempts
- or other undesirable activities, especially when logfile information
- from several hosts is merged.
-
- The optional access-control facility may be useful when, for whatever
- reason, it is not possible to handle access control at a more suitable
- level (such as an internet router).
-
- Enhancements over the previous release are: protection against rlogin
- and rsh attacks through compromised domain name servers, optional
- netgroup support for systems with NIS (formerly YP), and an extension
- of the wild card patterns supported by the access control files.
