Actually, it should show you all the gateways, not just the default route: G RTF_GATEWAY Destination requires forwarding by intermediary I thought that's what you said you wanted, maybe I was mistaken. From my machine: I think this shows that traffic using the default route, as well as any traffic to a destination in the range "172.31.192/19", uses the router 172.31.128.254; that is the gateway for both. [snip] I've tried this in the past and I tried again just now. It only shows the default router address. There is absolutely no mention of the other router ip address in the netstat output. There is a difference between the routers that are "out there", the routers that the system knows about (in the routing table), and the routers that are known about but only in a database somewhere. The information kept by the SystemConfiguration framework, as in your case, is only acted on when the corresponding interface is the "primary". This is determined by the ordering of the interfaces in the network prefs panel (in the "show" popup, select network port configuration; you can enable, disable, and reorder the interfaces shown there). Thus, a router associated to en0 will only be added to the routing database in the kernel when en0 is the highest interface in the above list that is enabled (checked) and active (has a signal (e.g., a cable plugged in)). By the way: I just accidentally deleted all my routes and lost internet connectivity by running "route flush". The only thing I could think of to do was: ...which seems to have worked. Would a reboot have fixed that problem As Andrew suggests, removing and replacing the cable, or enabling and disabling the interface (in the network prefs panel), should suffice. Rebooting a Mac OS X system is generally not needed, unless the software changes in some significant way (or cosmic rays intervene :-}). This email sent to site_archiver@lists.apple.com
