Friends,
I am trying to use devd to catch and do some extra processing on LINK_UP and
LINK_DOWN events for my net interfaces (e.g., notify my admin, log the
event, ...). Tried this on both FreeBSD 6.1 and on FreeBSD 6.2.
I used the following code (shows LINK_DOWN; wrote similar stuff for
LINK_UP):
notify 10 {
match "type" "LINK_DOWN";
action "logger -s alert: Caught LINK_DOWN on dev: $device-name
subsys: $subsystem";
};
Didn't work. I tried the above with both strict match conditions (using
vendor, device and class matches) as well as very general (like the above).
Didn't work.
I ran killed devd and ran it in the foreground with "devd -dD". Then I
logged into a different pty and used
ifconfig lnc0 down #(lnc0 is my ethernet device).
devd doesn't even seem to catch the event (no output at all - both on screen
and in syslog).
On the other hand, "nomatch" and "attach" messages do seem to get through (I
wrote similar stuff for nomatch & attach, and they are showing up at bootup
and in syslog).
What could I be doing wrong?
Regards,
