Can you be more specific? /usr/sbin/dhcpd is root:root.
/usr/sbin/dhcpd is being run as root.<br>

the ISC DHCP server (dhcpd) version 4.3.6 from a rocko Yocto <br>
build. When dhcpd is started without the '-f' or '-d' options
(forks to <br>
the background) it does not work. DHCP DISCOVER requests are
sent, but <br>
the dhcpd application does not respond. I can attach strace
to the <br>
dhcpd process and see that dhcpd just sleeps in an futex()
call.<br>
<br>
If I start dhcpd with either the '-f' or '-d' options so it
does not <br>
fork, then it works properly.<br>
<br>
I have run dhcpd (both forking and non forking) using strace
to see if I <br>
could spot any differences. The only thing I notice is that
when <br>
forking, the parent process terminates (expected) along with 3
other <br>
child processes/threads. It looks like these other threads
are supposed <br>
to handle the ISC tasks/messages, but are not cloned by the
fork and are <br>
not present after forking.<br>
<br>
For reference, with an older version of ISC DHCP server
(4.1.1-P1) on an <br>
older product, this problem does not occur.<br>
<br>
Any ideas where to look?<br>
