Hello, I'm trying to use "udhcpc" from busybox (The client, not the server)
to obtain classless static routes through a DHCP packet.
My DHCP server side (isc-dhcpd-4.1.1-P1) is configured with:
option rfc3442-classless-static-routes code 121 = array of integer 8;
option ms-classless-static-routes code 249 = array of integer 8;
and
option rfc3442-classless-static-routes 24, 192, 168, 123, 10, 10, 10, 1, 0,
192, 168, 1, 2;
option ms-classless-static-routes 24, 192, 168, 123, 10, 10, 10, 1, 0,
192, 168, 1, 2;
However on the client side I don't appear to source that data as part of
the DHCP query.
Here's the udhcpc client query strings I've tried:
/sbin/udhcpc -C $(dmidecode -s system-serial-number) -n -q -s
/etc/udhcpc/udhcpc.script -i eth0 -O 121
/sbin/udhcpc -C $(dmidecode -s system-serial-number) -n -q -s
/etc/udhcpc/udhcpc.script -i eth0 -O staticroutes
In /etc/udhcpc/udhcpc.script I'm printing the following to STDOUT to see if
the routes are pupulated:
echo "DHCP Boot Function = ${1} $2 $3 $4 $5 $6 $7"
echo "Broadcast = ${broadcast}"
echo "Netmask = ${subnet}"
echo "Domain = ${domain}"
echo "Leased IP = ${ip}"
echo "Router = ${router}"
echo "CIDR Route = $cidrroute"
It looks like "$cidroute" should be populated by option 121/staticroutes
but that doesn't work.
Any suggestions would be greatly appreciated.
Thank you,
-Alex
