Package: net-misc/dhcpd-3.0.1-r1 I had some trouble setting DHCP up for a network consisting mainly of Microsoft clients. After some research I found that Microsoft DHCP clients only accept DHCP messages which are addressed to "255.255.255.255", strictly conforming to the protocol declaration. Therefore, I think it should be nice to include an option in the init.d script for dhcpd to set the route for 255.255.255.255 for ${IFACE} (the interface the dhcp server is running on). A new option with a short explanation in conf.d/dhcp would be nice to toggle this behavior. This is how I modified my init.d/dhcp: *** dhcp.old 2005-06-28 17:09:14.253256181 +0200 --- dhcp 2005-06-28 17:23:52.145921442 +0200 *************** *** 23,28 **** --- 23,34 ---- ebegin "Setting ownership on dhcpd.leases" chown dhcp:dhcp "${CHROOT}/var/lib/dhcp/dhcpd.leases" || return 1 eend $? + + if [[ ${SETALLONES} == "1" ]] ; then + ebegin "Setting route for 255.255.255.255 to ${IFACE}" + route add 255.255.255.255 ${IFACE} || return 1 + eend $? + fi } start() { And this is the diff for conf.d/dhcp: *** dhcp.old 2005-06-28 17:27:18.752600550 +0200 --- dhcp 2005-06-28 17:26:00.638820421 +0200 *************** *** 6,11 **** --- 6,16 ---- # list all interfaces space separated. IFACE="ath0" + # Set the route for the address 255.255.255.255 to the interface dhcp + # listens on. + # This is required by some clients. All Microsoft clients need it. + SETALLONES="1" + # Insert any other options needed DHCPD_OPTS="-q" I think this small function would be welcome by many users.
I just found out that the error was caused by something else, since the daemon bypasses the Linux IP stack from kernel version 2.2 on. Setting the route is not necessary...
