I would assume that if you set defaults this way, defaults will also
take place if no lease is obtained at all - at least that would be very
usefull. Something like this I guess:
interface bge0 {
default {
fixed-address your-fixed-ip-here;
subnet-mask your-fixed-subnet-mask-here;
...
}
}
sorry, I still don't quite get what you mean. it seems my default setting
is this though it is not written in dhclient.conf.
how can I configure the wireless interface to use DHCP in dhclient.conf?
like as follows?
The dhclient.conf does not contain any interface configuration values
unless you write it. dhcp automatically reads dhclient.conf on startup,
so you just need to enable dhcp for the interfaces you want configured.
In rc.conf insert
interface_ath0=DHCP
interface_bge0=DHCP
Create dhclient.conf like this
interface ath0 {
default {
... the default configuration for your wireless nic ...
}
}
interface bge0 {
default {
... the default configuration for your wired nic ...
}
}
No need to mention any scripts in dhclient.conf. In the default
configuration you need to specify at least: ip address, netmask, router
and nameserver, see dhclient.conf(5) for the names of those variables.
You only need to create an interface specific section if you need to
configure the nic with values other than those provided by the dhcp
server. If your ath0 is always configured with dhcp (as I understood)
and you are happy with that, no need to make that section in the
dhclient.conf - or keep it empty.
Then run
# /etc/rc.d/netif restart
thanks for your kind suggestions :) it is very useful.
but, in my situation, there are two things needed to mention:
1. normally the wireless NIC is not in the kernel when system boots, so
no need to if_ath0=DHCP every time
2. usually I use my laptop in dormitory with a static IP address. so no
need to if_bge0=DHCP every time
finally, I figure out that ifconfig bge0 delete before I wanna use the
wireless NIC would sound better for me :)

Try to take a look at dhclient.conf(5) and dhclient(8) and set all
interfaces to be configured with dhcp. I think it should be posible to
configure default values so there is something to fall back on if a
lease is not obtained.
Note that dhclient is new in FBSD 6, this is also why you had to take
down the other interface. The old dhclient would reset all dhcp
configured interfaces, the new doesn't, which is quite neat because
usually you would have the two interfaces connected to /different/
networks.
thanks for your explanations about DHCP in FreeBSD 6.0, although I
still cannot find a way to config dhclient.conf to solve my problem :)
Of course I guess you read the man-page, but maybe you didn't see this:
yes, i do
The dhclient.conf file can be used to configure the behaviour of the
client in a wide variety of ways: protocol timing, information
requested from the server, information required of the server,
defaults to use if the server does not provide certain information,
values with which to override information provided by the server, or
values to prepend or append to information provided by the server.
The configuration file can also be preinitialized with addresses to
use on networks that do not have DHCP servers.
It appears you can set some default values:
default { [option declaration] [, ... option declaration] }
If for some set of options the client should use the value sup-
plied by the server, but needs to use some default value if no
value was supplied by the server, these values can be defined

You might want to toggle timeout so defaults take effect faster.
If both interfaces are configured with dhcp then dhclient will
unconfigure the interface if there is no connection be it wired or
wireless and the configuration of the working interface should take effect.
how can I configure the wireless interface to use DHCP in dhclient.conf?
like as follows?
interface ath0 {
default {
script /etc/dhclient-script;
}
}
looking forward more explanations

You don't. An interface is not configured to use DHCP by
modifying dhclient.conf. The dhclient.conf file is used by
dhclient to find out *options* for interfaces that are configured
to use DHCP in the /etc/rc.conf file. The rc.conf file is
the one you have to edit make sure that it contains something
like:
ifconfig_ath0=DHCP
Then, when dhclient *is* started for 'ath0' it will read the file
/etc/dhclient.conf looking for a matching set of options.

FWIW,
On my laptop, which has to switch between a couple of wireless networks and
my local LAN at home, I use custom shell scripts called ``/root/net/*.sh''
to encapsulate the changes I'd have to manually make.
I have prepared working sets of files, like:
/etc/resolv.conf_home
/etc/resolv.conf_work
and then run /root/net/home.sh which contains:
#!/bin/sh
if test -n $1 test -f /root/netstart-home-$1.sh ; then
mode=$1
else
mode=wlan
fi
echo ## Stopping local services
/etc/rc.d/named stop
/etc/rc.d/sendmail stop
echo ## Setting up /etc and /usr/local/etc files
(
cd /etc;
cp resolv.conf_home resolv.conf;
cp dhclient.conf_home dhclient.conf;
cp namedb/named.conf_home namedb/named.conf;
cd /usr/local/etc/postfix;
cp main.cf_home main.cf;
)
echo ## Bringing up the network connection
/root/net/netstart-home-${mode}.sh
echo ## Refreshing the firewall rules
/etc/rc.d/pf reload
echo ## Starting local services again
/etc/rc.d/named start
/etc/rc.d/sendmail start
The real work is done by netstart-home-wlan.sh or netstart-home-wlan.sh.
The wlan script is the one that sets up a wireless connection, and
contains:
#!/bin/sh
# Default setup for my bge0 interface.
export ifconfig_ath0=DHCP ssid 'gker' \
wepmode on weptxkey 1 wepkey

while [ $_timeout -lt 30 ]; do

break
fi
echo -n '.'
sleep 1
_timeout=$(( $_timeout + 1 ))
done
if [ X${_associated} = XYES ]; then

echo ''
echo Failed to bring up ath0. Aborting.
/etc/rc.d/netif stop ath0

if [ -n ${_oldrouter} ]; then
route delete default ${_oldrouter}
unset _oldrouter
fi
route add default $defaultrouter
fi
This seems to work remarkably well so far. All I need to do once the
laptop boots is to log in as root and run the proper /root/net/*.sh script
:)
thanks for your shell scripts. it is very appreciated.

However, in any case you should expect wierd things if both interfaces

dhclient handles that.
Let me know if the above works, it's always good to have this kind of
examples in the archive.

Try to take a look at dhclient.conf(5) and dhclient(8) and set all interfaces to be configured with dhcp. I think it should be posible to configure default values so there is something to fall back on if a lease is not obtained. Note that dhclient is new in FBSD 6, this is also why you had to take down the other interface. The old dhclient would reset all dhcp configured interfaces, the new doesn't, which is quite neat because usually you would have the two interfaces connected to /different/ networks.
