    SubjectProblems with ppp and 2.1.117+
    Hi. I have a problem with ppp and kernel 2.1.117+. I tried kernels
    2.1.117-126, ppp-2.3.5 and net-tools 1.45 on a machine that acts as a
    dialup server. The machine assigns dynamic IP-to to our clients. We use
    cyclades-z as serial devices with modems attached to them. Each serial
    port has an IP assigned to it. When a user connects to serial port N, a
    route is added for its IP

    Destination Gateway Genmask Flags Metric Ref Use Iface
    aaa.bbb.ccc.ddd 0.0.0.0 255.255.255.255 UH 0 0 0 pppQ

    Where aaa.bbb.ccc.ddd is the IP of the serial port and pppM is the
    dynamically assigned ppp interface.

    The problem appears when the pppd for that IP terminates or even is killed
    with SIGKILL. The route to that IP is not deleted. When another user logs
    on the same tty, a second route to the same IP is added and the routing
    table is:

    Destination Gateway Genmask Flags Metric Ref Use Iface
    aaa.bbb.ccc.ddd 0.0.0.0 255.255.255.255 UH 0 0 0 pppQ
    aaa.bbb.ccc.ddd 0.0.0.0 255.255.255.255 UH 0 0 0 pppR

    The user that has connected to the server sends packets successfully, but
    when a packet is send back to him it is routed through interface pppQ and
    never reaches the user.

    2.1.108 is the last kernel that works with our configuration.
    Any suggestions will be appreciated. Thanks in advance.
