    ORIGINAL QUESTION:
    I installed hp-ux ssh to replace telnet and it's
    running fine. My question is how to allow only IP
    range 198.152.*.* to access the SSH and restrict other
    IPs. Since HP-UX ssh is running its own daemon
    (/opt/ssh/sbin/sshd) and not using ‘inetd’, put the
    restriction in ‘inetd.sec’ won’t help. Thanks you for
    your help.

    SOLUTION:
    This is from Jorge Fábregas:
    You need to run the ssh daemon thru inetd. Do the
    following:
    1- Stop the ssh daemon
    2- Make sure it won't start on machine startup by
    editing /etc/rc.config.d/sshd
       Change SSHD_START=1 to 0
    3- Modify /etc/inetd.conf to enable ssh. You must use
    the "-i" switch in order to allow it to run thru
    inetd. I have the following line on my inetd.conf
    ssh stream tcp nowait root /usr/sbin/sshd sshd -i
    4- Modify /var/adm/inetd.sec accordingly. Something
    like: ssh allow 172.16.0.10
    etc...
    Now you can get the ip filtering benefits provided by
    inetd. Of course, this is one scenario. You can still
    use IPFILTER if you want (and keep running SSHD
    stand-alone).
    -----------------------------------------------------
    Use tcp wrappers with /etc/hosts.deny, /etc/hosts.allow.
