And Thomas Hood's ifupdown-roaming will handle this automatically, with a single interfaces file but, if your only way to tell which net you're on is whether or not you get an IP served by dhcp, there'll be a 30 second (iirc) delay while it waits for a response from the server (obviously you can change this value in your dhcp client). Most of the automatic network detections will look for a known MAC address, or similar test, to eliminate this delay. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
