For some reason iplog doesn't work for tun-devices I don't know why, I
think it happens after forking a new process, then a resource is not
available.
note this happens only if I run "iplog -i tun0", "iplog -i xl0" for
example works fine. Maybe it happens because tun-device is opened by
user-ppp. But a few month ago iplog works fine with tun-device although
the device was opened. I added two ifconfigs and one processtrace of
iplog.
