SCO Routing - SCO

    Default SCO Routing

    I have a SCO OpenServer 5.0.5 system which currently routes out
    through some ISDN routers. In a couple of weeks time this method of
    comms will be phased out and replaced.

    The new comms solution requires all routes to go out through a Firebox
    Firewall, which itself will be responsible for routing to the correct
    destination.

    I have tried testing this on one location, but everytime I delete the
    route, as soon as I "ping" the remote location, a route is added as
    follows which is the "original" route that I just deleted!!

    180.147.160.2 132.147.160.20 UGHD 0 3 net0

    Can anybody help on this or point me somewhere to look?

    Thanks in advance,

    Robin

    Well, someone has to be adding the route back in, and my guess is routed
    which is started at boot time in /etc/rc2.d/S85tcp. Unless you actually
    want your SCO machine to be a router (you almost surely dont...) you can
    safely uncomment the few lines that start this nuisance up.

    I wonder what you will see in /etc/resolv.conf when you look there...

    I stopped routed running and the route still came back.

    There is no /etc/resolv.conf file on the system.

    Thanks for the advice Jeff .... I took it and told the customer they
    "had" to renumber their network regardless of what their "comms
    supplier" said ..... unbelievably a company that specialises in comms
    over the internet said those IP addresses would not cause a problem!!

    As soon as I mentioned that their IP addresses belonged to SCO/Caldera
    the IT manager said "ahhhhh. that explains a few things on the
    firewall such as requests for ns0.caldera.com etc"

    The re-numbering plan has been started and will take place over the
    next month. I will start putting together the "road-map" :)

    Thanks for the time you have spent on this Jeff.

    Regards,
    Robin.
