What are TCP Wrappers?
TCP Wrappers are a mechanism that provides access control, list restrictions
and logging for all service requests to the service it wraps. It may be used
for either UDP or TCP services as long as the services are invoked through
a central daemon process such as inetd.
TPC Wrappers performs a few simple but very important tasks. It checks the
access control list to determine whether a connection should be allowed and
submits a log entry to the daemon syslogd. If the access list allows
the service, tcpd (TCP Wrappers daemon) invokes the appropiate daemon,
which then proceeds with its own authentication mechanism (if applicable) and
may write its own message to syslogd.
TCPW module for Webmin
The module performs a scan of services handled by the inetd
daemon and bolds those who are protected by the tcpd daemon. You can click on
any service showing a series of features about it.
It also shows the access rules defined in the /etc/hosts.allow and
/etc/hosts.deny files. You can click on any rule defined to edit it or
you can simply add a new rule.
