Resubmitting because the "email client ate my homework (patch)" last time. So
much for Hotmail's "plain text" mode!
==
When restarting the networking subsystem (for example, by running
"/etc/init.d/network restart"), I find that my WAN interface is brought up
without an IP address or routing information applied.
I narrowed it down to the fact that the UDHCP script does not try to
reconfigure the interface if all of the data (IP address, netmask, etc.)
remains the same from the last time the DHCP client ran on the interface. While
this is all well and good in the case of a DHCP renewal, it means that your
newly-brought-up interface (which lost its IP config information when it went
down as part of the restart) doesn't have its IP address applied.
I adjusted the script so that it actually configures the interface in the event
that we are trying to bring it up ($1==ifup).
Or maybe someone knows of a better way to fix this?
