True only if your options for ifconfig in rc.conf would clear or
override whatever it is you put in /etc/start_if_em0. As long as its
something that can be done with multiple ifconfigs then all is fine.
For example this works fine in /etc/start_if.xl0:
ifconfig xl0 lladdr 00:01:23:45:67:89
with this in rc.conf:
Thank you very much for the above info David, I've always been
challenged with my (encrypted) wireless card though, and usually have
my own manual script that I run. Always wanted to have it start
"automagically" when/if it is the card I'm using.
Besides the single line you have in /etc/rc.conf above to instruct DHCP
to be used, can one place all the following somehow in rc.conf or will
I have to get this going in a script location?
Currently I give my card a static ip but would like to have it grab
it's ipaddr by DHCP, here is the majority of the script, omitted are
my ping tests of the gateway at the end.
The reason you do not put a script such as you describe within rc.conf
is that rc.conf is widely sourced as part of other scripts. As such, its
run many times, not just once at boot.
I think you should be able to remove the ifconfig setting static IP
address, and the "route add" from your script, name the script
if_start.wi0, and add "ifconfig_wi0='DHCP'" to rc.conf and be in
business (assuming your wireless access point serves DHCP).
Thats the whole point of start_if.<if_name>, to do things such as change
MAC addresses, set WEP keys, etc. Things which lack formal support in
