    Here's how I have mine setup.

    /etc/hosts.deny
    ftpd:ALL:
    telnetd:ALL:
    ALL:ALL:

    then in /etc/hosts.allow I have individually listed the IP's that can
    connect. Or their whole class c.

    telnetd:10.10.1.
    telnetd:10.1.1.65

    Are you trying to JUST Deny specific hosts and allow the rest?
    Or do you want to deny all hosts, and allow certain ones to get through?

    hosts.allow contains nothing.

    Do you have anything in your hosts.allow file?

    Hail All,

    I have installed tcp wrappers in AIX 4.3 (P270) machine.
    And configured the /etc/inetd.conf as to block telnet and ftp daemons
    and added entries in /etc/hosts.deny as follows:

    But, the system is blocking these for all the machines which try to
    connect
    this machine.
    Please provide solution.

    /etc/inetd.conf entry:
    ------------------------
    telnet stream tcp6 nowait root /usr/sbin/tcpd -l -d telnetd
    ftp stream tcp6 nowait root /usr/sbin/tcpd -l -d ftpd

    /etc/hosts.deny entry:
    ----------------------

    in.telnetd: <other machine ip address>
    in.ftpd: <other machine ip address>

    thanks and regards
