=========================<br>
My analysis:<br>
<br>
I guess that the pay load is <b>struct fib_rule_hdr</b><br>
struct fib_rule_hdr {<br>
__u8 family;<br>
__u8 dst_len;<br>
__u8 src_len;<br>
__u8 tos;<br>
<br>
__u8 table;<br>
__u8 res1; /* reserved */<br>
__u8 res2; /* reserved */<br>
__u8 action;<br>
<br>
__u32 flags;<br>
};<br>
<br>
<br>
<blockquote type="cite"> [PAYLOAD] 12 octets<br>
02 00 00 00 0a 00 00 01 00 00 00 00 ............
</blockquote>
so
<pre wrap="">family = 02 , fine
</pre>
table = 10, fine<br>
but <br>
src_len =0 !!!! should be 32<br>

<pre wrap="">Hello guys,
I am using libnl 3.0 from git (cc33b0940f8ca0a34c9fbc085963e7887adc4db7)
I am trying to add rules to the kernel routing engine, using libnl.
(kernel 2.6.35-28-generic x86_64 GNU/Linux / Ubuntu)
What i'm trying to do would be , with iproute2 :*ip rule add from
127.0.0.1 table 10 prio 100*
There is not any tool like src/nl-rule-add.c yet, so i did my own , you
can find it as attachement.
It seems that the call :*rtnl_rule_set_src(rule, a)* doesn't have any
effect.
Do you have any idea?
I tried to compare with iproute2 code source, but that's not that easy.
They use a struct "struct rtmsg", that is not use in libnl.
Any help would be welcome....
</pre>

<pre wrap="">Can you run your program like this:
NLCB=debug src/nl-rule-add
and post the output? That allows veryfing the netlink message that is being
sent to the kernel.
