With the programs that come with this kit you can monitor and control
who connects to your TFTP, EXEC, FTP, RSH, TELNET, RLOGIN, FINGER, and
SYSTAT network services, and many others.
Optional features are: access control based on pattern matching; remote
username lookup using the RFC 931 protocol; protection against attacks
from hosts that pretend to have someone elses name; protection against
attacks from hosts that pretend to have someone elses network address.
The programs can be installed without requiring any changes to existing
software or configuration files. By default, they just log the remote
host name and do some sanity checks on the origin the request. No
information is exchanged with the remote client process.
The most notable differences with respect to the previous release are:
- Support for System V.4-style TLI, a protocol-independent network
programming interface. When the programs find out that TCP/IP is
being used underneath TLI, they behave exactly as in the case of
socket-based applications. In case of other underlying protocols,
the optional remote username lookups will not work, and the network
address information is in some generic universal format so that
net/mask patterns will probably not work either.
The default mode of operation (no TLI support) should be identical to
earlier versions.
