[Olsr-users] trying to get olsr run on a macbook

[L. Aaron Kaplan]

Sure I can tell you, here is how to trace in Mac OS X:
(CCed to the list so that the answer stays in the ML archive)


ultrastabil:olsrd aaron$ sudo dtruss ./olsrd  -d 1 -i en1


You then should see something like this:

select(0xB, 0x7FFF5FBFF410, 0x0, 0x0, 0x7FFF5FBFF490)		 = 0 0
sendto(0x6, 0x100800000, 0x14)		 = 20 0
select(0x0, 0x0, 0x0, 0x0, 0x7FFF5FBFF470)		 = 0 0
select(0xB, 0x7FFF5FBFF410, 0x0, 0x0, 0x7FFF5FBFF490)		 = 0 0
select(0xB, 0x7FFF5FBFF410, 0x0, 0x0, 0x7FFF5FBFF490)		 = 0 0
select(0x0, 0x0, 0x0, 0x0, 0x7FFF5FBFF470)		 = 0 0
select(0xB, 0x7FFF5FBFF410, 0x0, 0x0, 0x7FFF5FBFF490)		 = 0 0
write_nocancel(0x1, "-\r\0", 0x2)		 = 2 0
select(0x0, 0x0, 0x0, 0x0, 0x7FFF5FBFF470)		 = 0 0
select(0xB, 0x7FFF5FBFF410, 0x0, 0x0, 0x7FFF5FBFF490)		 = 0 0
sendto(0x8, 0x100800600, 0x14)		 = 20 0
select(0x0, 0x0, 0x0, 0x0, 0x7FFF5FBFF470)		 = 0 0
select(0xB, 0x7FFF5FBFF410, 0x0, 0x0, 0x7FFF5FBFF490)		 = 2 0
recvmsg(0x5, 0x7FFF5FBFE150, 0x80)		 = 20 0
recvmsg(0x7, 0x7FFF5FBFE150, 0x80)		 = 20 0
select(0x0, 0x0, 0x0, 0x0, 0x7FFF5FBFF470)		 = 0 0
select(0xB, 0x7FFF5FBFF410, 0x0, 0x0, 0x7FFF5FBFF490)		 = 0 0
select(0x0, 0x0, 0x0, 0x0, 0x7FFF5FBFF470)		 = 0 0
select(0x0, 0x0, 0x0, 0x0, 0x7FFF5FBFF470)		 = 0 0
select(0xB, 0x7FFF5FBFF410, 0x0, 0x0, 0x7FFF5FBFF490)		 = 0 0
(...) etc


One more thing which could be a slight problem for you:
Make sure that the IP4Broadcast is *not* set to 255.255.255.255.
All BSD derived systems do not simply accept this setting. Unfortunately.

from my config file:

    #Ip4Broadcast       255.255.255.255


You can see it is commented out.
