772.0. "Hubwatch T2.8, SLIP connection dies, HELP!" by WOTVAX::HATTOS (I think, Therefore I'm paid less) Sat Feb 26 1994 11:20

    I have scanned for occurences of SLIP but none of then answer this
    question....
    
    
    I have a Laptop on which I have installed Hubwatch T2.8, I selected
    NDIS and SLIP and answered all the config. questions.
    
    What I want to know is can I use SLIP from my laptop to manage the
    HUB900 in this configuration.

                  16.182.224.178
    
    
    I have tried, and can get a SLIP connection working to the DECserver
    and can then ping the Hub manager and the repeater 900, however when I
    start windows the SLIP connection dies completely.
    
    In my Windows setup, I have 'no network installed', I guess this is my
    problem.. but how do I cure it? How do I tell Windows that I am using
    SLIP on the serial port?
    
    I really need to get this running quickly because I have to set up a
    Hub using my laptop next week. 
    
    If this is not possible... why is it not? The Hubwatch install gives
    you SLIP so you should be able to do this.
    
    Thanks for any help,
    Stuart

    First of all, if you want to manage the hub you need to connect
    directly to the OBM port on the hub, not to the DECserver900.  The OBM
    port is the 9pin connector on the agent (next to the RJ45 for the setup
    port).
    
    	Your serial port must be 8 bits, 1 stop bit, No parity, and the
    baud rate must match that configured using the Hub setup port (9600 by
    default, but make it higher if your PC can do it).
    
    If you're using a modem, then a standard PC-modem cable will work.
    
    If your're trying to do a direct connection you need to use a 'modem
    eliminator' that crosses DTR/DSR, CTS/RTS, and Tx/Rx; just as you would
    if you wanted to connect two PCs together via the serial ports.

    OK,
    
    given I have to do it this way, why does my SLIP connection die when I
    go into windows?
    
    Thanks anyway!

772.4In-Band-Out-Of-Band WarningQUIVER::SLAWRENCETue Mar 01 1994 19:2223
    
    A word of warning about:
    
    > The setup in .0 should work:
    >        laptop -- H8571-J -- BN24h-03X -- DECserver
    >    You must use the hub's in-band ip address in this case.
    
    We call this 'in-band-out-of-band'; your connection to the hub goes
    through the SLIP line, but the packets must also go across the ethernet
    backplane connection and through the repeater.  This means a lot of
    extra stuff that must be working for your management messages to get
    through, and means that your management traffic is on the same network
    as your users (which the original poster seemed concerned with).
    
    While the above might (under normal circumstances) work, it would have
    no advantages and several disadvantages over a direct connection to the
    OBM port on the hub.
    
    One case that you may run into is a hub that has no module capable of
    acting as the IP Server (this should become less of a problem, as most
    new modules will be able to do this).  In that case, you can connect
    a port on the terminal server to the OBM port and get to the agent that
    way.  Again, this is not really out-of-band.

                               -< Some help... >-
--------------------------------------------------------------------------------
    Here's some suggestions:
    
    The setup in .0 should work: 	
    	laptop -- H8571-J -- BN24h-03X -- DECserver
    You must use the hub's in-band ip address in this case.
    
    
    .1 should also work:
    	laptop -- H8571-J -- DECconnect office cable -- H8571-J -- 900 hub
    								   OBM port
    You must use the hub's out-of-band ip address in this case.
    
    Edit your pwtcp.ini file. In the [TCPIP] section, make sure the
    NetworkType line is:
    
    NetworkType=2
    
    Edit your strtslip.bat file. Make sure the dllasync line is:
    
    dllasynch /DATA_BUFFER_SIZE:1024
    
    If your laptop has only one serial port, and you usually have the mouse
    connected on that port, you won't be able to do much with hubwatch. You
    must change your windows setup so that windows thinks you have no mouse
    installed. Otherwise, windows will try to initialize the mouse when it
    starts. It usually sets the DECserver back to local mode so further
    slip communication will NOT work. 
    
    Lastly, if you have more than one serial port, try using slip on the
    other port (comm2). We have had one case where slip would not work on
    comm1 but worked fine on comm2. It was most likely some kind of
    configuration problem on that pc but we couldn't find it. 
    
    Try installing pathworks 5.0 on your laptop. If you can run slip on
    your comm port using pathworks, then hubwatch should work fine. If you
    can't run using pathworks, then hubwatch will not run either. Perhaps
    the pathworks people could be of more help at that point.
