    I like the control Linux used to give me. I ifconfig up the interface,
    the machine starts responding to that IP address. (e.g. for requests
    from inside the machine). Once I add the route, I can start using that
    IP address from the other machine(s) on that interface.

    I regularly have both a token ring connection between two machines,
    besides the ethernet connection. I get bothered by the kernel defining
    routes that I don't need. My "subnet" is on the ethernet, there is
    usually just one other machine on the token ring interface. I have to
    remember adding "netmask 255.255.255.255" on the ifconfig line every
    time I up the token ring interface.... (which without the netmask
    specification could easily be done by hand, but now requires a small
    script)

    Roger.
