Hi,
i wish to share a simple patch to bypass the problem showed in my previous mail.
the patch fix 2 problems:
1- with the original "/sbin/dhclient-script" you don't get the
default gateway if it is
on a different subnet then your IP.
2- when you put down the interface with "ifconfig rl0 down" and then you
rerun "dhclient rl0" , you don't get the IP configured and with a
little of debug i
found the the dhclient-script execute:
ifconfig rl0 inet 84.223.120.116 netmask 255.255.255.255 broadcast
84.223.120.116
ifconfig: SIOCAIFADDR: File exists
the problem is that you have a route that conflict with the command:
84.223.120.116/32 link#3 UC 0 0 - rl0
the route is added the first time and didn't get deleted on a FAIL event
(the env is not set by dhclient, i don't know why).
the second time you run "dhclient rl0" the old_IP and the new_IP is
the same and so
the delete_old_routes is not executed.
i corrected the problem commenting out the line:
route add $new_ip_address 127.0.0.1 >/dev/null 2>&1
since when you normally configure a static IP address you don't
configure such route
(please if you know a reason to leave this route let me know).
here the patch to /sbin/dhclient-script:

and i just solved my problem of getting the IP address on my openbsd machine.
i wish to share my experience here, feel free to correct my english :P
[...snip...]
you can try without the 2 "route add" command if it works, i had to use them
because the gateway is on a different subnet of my public IP and the dhclient
command doesn't configure it automatically (anyone know another
solution to this?).
