Hi Folks, what do you think about this temporary
solution untill we have a full working dhcp client which
does the same as win XP :P ?
This patch does read the fix dhcp interfaces from
rc.conf, starts itself with the pccard interface _AND_
the system interface (if one or more exist). Then, after
removal, it kills the existing dhclient, and starts again
one from rc.conf without the pccard one.
I could fix that just easy to work with more pccards.
Currently it only works with one. And of course rc.d/dhclient
needs to be fixed to include the pccard interface if it has
been attached _before_ devd has been started.
My rc.conf config is simple:
ifconfig_sis0="DHCP"
pccard_ifconfig=DHCP
removable_interfaces="an0 wi0"
It just works great. (Btw. the IMAPI way of adding/removinf interfaces
is complety broken, and even the authors told be that it not working and
difficult to fix)
Comments ?
