TCP Wrappers Release Notes

What’s in This Version
TCP Wrapper Features
Chapter 1 9
For the rlogind service, a null character (\0) must be placed at the
beginning of the rlogind banner file, as specified in the following
example:
# echo "\0 Text to demonstrate the banners" > rlogind
# echo " option in tcpd(1M)." >> rlogind
Configuration
TCP Wrappers on HP-UX uses the /etc/tcpd.conf configuration file. This
file can be used to set time-out on client username lookups, log level, and
action to be taken in case of reverse lookup failure.
What’s in This Release
The following are the binaries distributed with this release of TCP
Wrappers:
• tcpd
The tcpd program will log the client hostname address and the
remote username who owns the connection, if applicable and perform
some additional access control checks. When it is through with all
the checks, the wrapper executes the desired server program and
exits.
The following are the methods to use the tcpd program:
1. Edit the /etc/inetd.conf file as follows:
telnet stream tcp nowait root /usr/lbin/telnetd telnetd
becomes:
telnet stream tcp nowait root /usr/lbin/tcpd \
/usr/lbin/telnetd telnetd
Only the last component of the pathname /usr/lbin/telnetd,
telnetd will be used for access control and logging.
Similar changes will have to be made for other services, which
need to be covered by tcpd. You also need to re-configure
inetd(1M) process by running the command ‘inetd -c’ on the
command line to reflect the changes.
