possible patch for implementing split DNS

I need some processes to look elsewhere for DNS information from where the rest of the system looks.. This patch seems to me a simple solution. We over-ride where the resolver looks for resolv.conf using an environment variable. This would allow me to reset this to an application specific config

I believe Apple creates /32 host-specific routes for Zeroconf traffic on the other interfaces, if seen. That may actually just be the normal ARP-handling code in operation rather than Zeroconf, per se, although Apple's implementation of ARP is Zeroconf-compliant in terms of timing, setting "s

Hi. I'm trying som file transfers across the globe. The RTT is almost 400ms and the transfer rate is painfully slow. There are 24 router hops on the path and I assume most of the problem is there but I wonder if there are any sysctl variables I can trim on my side to help this problem slightly? I
