Examples that show some features of TCP wrapper
If you just want to restrict ssh connections without configuring or using /etc/hosts.deny, you can add the following entries to /etc/hosts.allow:
sshd: ALL: DENY
The version of TCP wrapper that comes with Red Hat also supports the extended options documented in the hosts_options(5)man page. Here is an example how an additional program can be spawned in e.g. the /etc/hosts.allow file:
For information on the % expansions, see “man 5 hosts_access”.
The TCP wrapper is quite flexible.
And xinetd provides its own set of host-based and time-based access control functions. You can even tell xinetd to limit the rate of incoming connections.
