With this package you can monitor and filter incoming requests for the
|
|
SYSTAT, FINGER, FTP, TELNET, RLOGIN, RSH, EXEC, TFTP, TALK, and other
|
|
network services.
|
|
|
|
The package provides tiny daemon wrapper programs that can be installed
|
|
without any changes to existing software or to existing configuration
|
|
files. The wrappers report the name of the client host and of the
|
|
requested service; the wrappers do not exchange information with the
|
|
client or server applications, and impose no overhead on the actual
|
|
conversation between the client and server applications.
|
|
|
|
Optional features are: access control to restrict what systems can
|
|
connect to what network daemons; client user name lookups with the RFC
|
|
931 etc. protocol; additional protection against hosts that pretend to
|
|
have someone elses host name; additional protection against hosts that
|
|
pretend to have someone elses host address.
