The following books are *NOT* easy reading, but will teach you nearly everything about how networking works: 'TCP/IP illustrated' Volumes 1 and 2 (3 is optional) "Internetworking with TCP/IP' Volumes 1 and 2 (3 is 'programming') These are the 'bibles' that virtully every professional has on their reference shelf (becaue they cover *everythig* from the very basics up), along with 'Unix Network Programming', which gets into the nitty-gritty details of the internals of writing software that communicates over the network. See also "TCP/IP Network Administration". This is an "O'Reilley Associates" book. Virtually *everything* they publish is excellent. If they've ever published an even mediocre book, _I_ have never encountered it. For 'minimalist'/'simplistic' descriptions of specific terms, see: <http://h30097.www3.hp.com/docs/base_doc/DOCUMENTATION/V50A_HTML/GLSSRYXX.HTM> Google for 'unix glossary of terms' for attidional useful wordists. > So, what I did is I disabled bge > completely, i.e. removed from /etc/rc.conf, > and I remembered to include wlan0 in > /etc/ipf.rules. This works ok. AH, if it is an 'either/or' situation, then life is a lot simpler. The 'ifconfig -a' output showed that _both_ interfaes were configured, "UP", with an IP address, *AND* that _both_ were connected to 'something'. Using both interfaces at the same time is significantly more complicated. 'Doable', just a bit tricky. And how you do it depends on 'whiich way' is 'out' (to the rest of the world.) > I'll need to think of an easy system > to switch from bge to bwn. I usually > use bge with static ip address at work > and I'm trying to use bwn at home. Write two simple shell sripts. One that doess the things you just did to 'remove' bge0, and enable bwn0/wlan0. And another that removes the bwn0/wlan0 references and adds the bge0 stu back in. If you're doing this by manipulating the rc.conf settings, then you can even stick an automatic reboot in the end of each of those scripts. If you turn on the machine and it comes up in the 'wrong' configuration, just run the script to change to the 'other' one. And reboot, if the script doesn't do it for you. When you have a better understanding of networking, and the the basic networking configuration commands ('ifconfig' and 'route', primarily), you can write scripts that make the operational changes -without- needing to reboot. Then you can leave the 'boot' configuration at whatever you 'normally' use (probably 'work'), and run the 'wireless' script to take down the ethernet ad bring up the Wi-Fi. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
