And I'd be happy to introduce you to them. I wouldn't swear to it, but I think dnsmasq might do the former out of the box. In any case, I know for certain I have seen this behavior multiple times, enough to learn to watch out for it. Looking back through my notes, it might have been seen with a stock WRT54G and another device with OpenWrt dnsmasq. The Zhone/Paradyne DSL modems that Integra deploys are in the latter category. In fact, by default, they hand out leases over the entire available address range (.2 through .254 in a /24). They don't bother to check whether the IP address is in use (e.g. by pinging) before hand. This makes trying to use static IPs on these networks highly problematic. It is just a matter of time before the helpful DHCP server cheerfully stomps on your carefully chosen IPaddr. Just as a capper, Integra refuses to provide a login to let you configure the DSL modem yourself. Which means, every trivial little change you might want to make requires a support call. -- Russell Senior, President [email protected] _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
