And of course, you can also automate this via devd.conf(5), by instructing the system to run the rc.d scripts or other commands/scripts if one of your NICs is attached/detached, or upon other conditions. There are related examples in the devd.conf(5) manpage and the default /etc/devd.conf b. ___ 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"

switching from one network interface to another without reboot
Hello, How can I switch from one network interface to another without rebooting my system (7.2R)? Problem description: I've got a laptop with two network interfaces (wired em0 and wireless ath0). Every now and then I have to set up a DSL wireless box which comes with default settings so that I have to start with connecting my laptop via em0. em0 gets IP address from wireless box by DHCP. I log in to web interface and set everything up including WLAN and restart wireless box. At this point I would like to switch to ath0 and start using internet connection via wireless box. I'm taking em0 interface down with "ifconfig em0 down" and unplug the cable. I'm changing /etc/rc.conf entries to: ifconfig_em0="NOAUTO" ifconfig_ath0="WPA DHCP" Then I'm doing "/etc/rc.d/netif restart" and ath0 gets IP address via DHCP and is connected to wireless box (/etc/wpa_supplicant.conf is set up). But whenever I try to ping anything (including wireless box) I get "interface down" message because my system still tries to use em0. What else should I do to tell it that I'm connected to network via ath0 now? Any suggestions are welcome.
