Description Michael 2022-04-24 19:23:48 UTC

until 13-RELEASE a simple line in rc.conf worked perfectly getting ip-address on boot and after disconnect and reconnect the device

ifconfig_ue0="SYNCDHCP"

now on 13.1-Stable I need to issue "sudo /etc/rc.d/dhclient start ue0", or, after fiddling this out, set in rc.conf:

network_interfaces="ue0"
netwait_if="ue0"
ifconfig_ue0="SYNCDHCP"
background_ntpdate="YES"

that is ok even if not written anywhere, or I didn't found it

but still it just assigns IP on boot, disconnecting the device dhclient-script seems to kill itself and does not restart after reconnecting the device, so far I could not find out where the problem is but suspect dhclient-script, until then I need manual execute  

sudo /etc/rc.d/dhclient start ue0

some solution for this?

Comment 1 Michael 2022-04-25 12:06:17 UTC

I added this block to devd.conf

notify 0 {
match "system" "IFNET";
device-name "ue0";
action "service dhclient quietstart $device-name";
};

and it is working now

certainly a workaround for me, but I think that should be in there by default
