1780.0. "Ping to Hub900" by KAOFS::S_BAINS () Tue Dec 13 1994 16:38

    I am trying to get Hubwatch V3.1 running on my laptop which has no
    ethernet. So I have configured it to use SLIP from the comm port. I set
    up the Hub900 IN-Bound and Out-Bound IP addresses. 
    When I try to PING the Hub connecting a cable from the comm port to the
    OBM port ( I made up a cable which is the same as BC29Q-xx) I get no
    response.
    I checked my pwtcp.ini file and everything looks ok, so I am not sure
    whats going wrong. Of course I need to be able to PING to the Hub
    otherwise when I try Hubwatch it will not work.
    The only module that I have in the Hub is a Decrepeater900TM.
    
    Any help would be appreciated

1780.1check these things outNETCAD::CURRIERWed Dec 14 1994 14:179
    Check the speed of your OBM port.  Does it match that of your comm
    port?  Also, the MAM expects full rs232 at the OBM port.  Verify that
    you cable supports all the signals.  We've had bad cables in the past.
    When you say that you've set up the Hub900 IN-Bound and Out-Bound IP
    addresses I assume that you selected the 'Set Out-if-Band Interface IP
    Address' entry on the set-up menu.  Also, make sure that the adaptor
    that you have conencted to the OBM port is H8571-J.
    
    
1780.2a little closerKAOFS::S_BAINSWed Dec 14 1994 14:5410
    Well I am a little closer, I can now ping the hub (i had to make the
    laptop IP address the same as the OBM IP address). Now when I start
    Hubwatch from windows and give it the OBM ip address I get back that
    the agent does not respond. I have double checked my files and the
    PWTCP.ini file and all looks OK. The Hub900 that I am playing with is a
    stand alone ie not connected to anything and the one module that is in
    the hub is a Decrepeater900TM. I should still be able to bring up
    Hubwatch right!

1780.3Pinging yourself?NAC::FORRESTThu Dec 15 1994 10:277
    Santokh, I think that by making the Laptop IP address= Hub OBM IP
    address, you are really getting the Ping response from  your Laptop.
    
    Have you checked out the instructions in Appendix B in the HUBwatch
    Installation and Configuration manual?

    Jack,
    
    I went thru appendix B several times and everything looks okay. It said
    in the manual to make the pc ip address the same as the OBM port
    address (iwas a little confused there) this was on page 2-5 Hubwatch
    for Windows USE manual

1780.5PC IP <> OBM IPNETCAD::SLAWRENCEFri Dec 16 1994 12:2012
    
    Those setup instructions are a little misleading.
    
    IF you are connecting the OBM port to a Terminal Server port in order
    to provide SLIP to it, then the 'Host Address' configured for that
    Terminal Server port must be the same as the OBM port address for the
    hub it is connected to.
    
    IF you are connecting a PC or other NMS system directly to the OBM port
    using a crossover cable or modems, then the IP addresses of the hub OBM
    port and the PC must be different.
                                                             
1780.6thank for the helpKAOFS::S_BAINSMon Dec 19 1994 12:397
    Thanks for clearing that up for me. I am going to take another look at
    the cable that I made up, maybe I'll just order the right cable.
    
    
    Thanks for the help

1780.7still no goKAOFS::S_BAINSThu Dec 22 1994 12:517
    I have the right cable now, but I still cannot Ping to the hub. What
    should my IP Mask be set for?. Right now I have it set for
    255.255.255.2
    
    thanks

    Try just describing in as much detail as you can stand, including your
    PC configuration file contents and the output on 'Show Current
    Settings' of the hub setup port.
