Routes appearing on OSR505 box - SCO

The gateway is a Cisco router, and has had 'no ip redirects' inserted into the ethernet interface. At a guess, I'd say these were RIP or another routing protocol's handy work (no 'D', thus not redirects), but I don't have 'routed' or 'gated' running on the server.

    Default Routes appearing on OSR505 box

    Hi,

    I've got an OSR 5.0.5 machine on the network at a clients, and routes (as
    shown below) are appearing.

    The gateway is a Cisco router, and has had 'no ip redirects' inserted into
    the ethernet interface. At a guess, I'd say these were RIP or another
    routing protocol's handy work (no 'D', thus not redirects), but I don't
    have 'routed' or 'gated' running on the server.

    What else would cause routes to show up in this manner ?

    Have you read the TA entitled "Routes are mysteriously showing up in my
    routing tables", [url]http://stage.caldera.com/cgi-bin/ssl_reference?107690[/url] ?

    | Yup. Thus why I said "no 'D'", and that IP redirects have already
    | been disabled.

    You can disable your machine from *sending out* ipredirects, but that
    does not stop some router from send them in.

    | The magically appearing flags are just 'UGH'.

    It would be worthwhile re-addressing this issue at a BOF for OSR5
    if you are going to forum. It was brought up last year, and a few
    people agreed that they have seen this issue. The problem seems to
    happen more often in my customer base when
    1) there is more than one cisco router involved
    2) the network link from the server to the client is not perfect,
    i.e. may be losing packets or have temporary "no route to destination"

    I have had the unusual effect of tangling up the lpd print queues, even
    though a telnet session was working through a VPN from a branch office
    to the head office. Even with the default route being correct, routed
    and gated off, no icmp redirects from the router, adding in a host route
    to the printserver restarted the print queue.

    I have mused if the problem may be started when a connection is working,
    say from a branch office to the head office, yet for a moment the WAN
    becomes dead. A "no route to host" packet comes in for the branch office
    subnet, yet some connections are still working. Somewhere in the OSR5
    network routing stack a host route is created for the working connection,
    hence the strange route table.
