Hi, [I've posted this to the freebsd-questions list previously but the problem was not resolved. In any case my apologies if you see this request twice] I'd like to use both ethernet and wlan, whichever is available, with my laptop. In many cases I prefer wlan at home as I'm not tethered and performance is good enough. However, in some cases I prefer to connect to a switch via ethernet to have faster connection to a desktop PC. I followed these instructions: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/network-aggregation.html Specifically, I use the rc.conf entries mentioned in the box at the very bottom on the page, except that my ethernet interface is re0 instead of bge0. The lagg module is loaded during boot using an appropriate entry in /boot/loader.conf. Things almost work: boot with ethernet plugged in, ethernet still in: connected via ethernet boot with ethernet plugged in, ethernet out: connected via wlan boot with ethernet unplugged, ethernet still out: connected via wlan boot with ethernet unplugged, ethernet in: no connection What bothers me is the last scenario: this would force me to boot with ethernet plugged in whenever I intend to use ethernet in the same session. Is this expected behaviour? Is there a way to fix this? The relevant config files are attached below. regards, Markus /boot/loader.conf: verbose_loading="YES" # print verbose loader output during boot coretemp_load="YES" # intel temp sensor support hw.psm.synaptics_support="1" # improved touchpad support atapicam_load="YES" # access CD drive through SCSI subsystem cuse4bsd_load="YES" # required for webcamd sem_load="YES" # required by firefox for displaying HTML5 if_lagg_load="YES" #link aggregation /etc/rc.conf: hostname="wombat.mininet" ifconfig_re0="up" ifconfig_iwn0="ether 00:1e:33:26:4c:3e" wlans_iwn0="wlan0" ifconfig_wlan0="WPA" cloned_interfaces="lagg0" ifconfig_lagg0="laggproto failover laggport re0 laggport wlan0 DHCP" sshd_enable="YES" moused_enable="NO" powerd_enable="YES" powerd_flags="-a max -b adaptive -i 90" cupsd_enable="YES" mysql_enable="YES" linux_enable="YES" dbus_enable="YES" hald_enable="NO" anacron_enable="YES" # Set dumpdev to "AUTO" to enable crash dumps, "NO" to disable dumpdev="NO" # -- sysinstall generated deltas -- # Thu Feb 16 22:33:22 2012 rpcbind_enable="YES" rpc_statd_enable="YES" rpc_lockd_enable="YES" nfs_server_enable="YES" nfs_client_enable="YES" devfs_system_ruleset="localrules" fusefs_enable="YES" -- Markus Hoenicka http://www.mhoenicka.de AQ score 38
