Yes.  IP hidden but:

t-bone at 602744 [/usr/local/nagios/libexec]# sudo -u nagios ./check_tcp -H
xx.xxx.xxx.xxx -p 23
TCP OK -   0.030 second response time on port 23|time=  0.030

Nagios can ping, and notes ping is up, for that host.  But cannot
check_telnet.  This is answering fine:

define service {
        host_name               XXXHOSTNAMEHEREXXX
        service_description     cisco
        check_command           check_ping!100.0:20%!500.0:60%
        max_check_attempts      4
        normal_check_interval   12
        retry_check_interval    1
        check_period            always
        notification_interval   0
        notification_period     always
        notification_options    w,u,c,r
        contact_groups          admin
}
