Bill,
I think there is different syntax for this, I used to
use something like:
if(len_gt(max_len))
{
}
But, I don't check for max length any more. Operating system
assembly/disassembly for
packets bigger than the mtu is transparent to me, I often work with
big packets. Also,
the mtu is different depending on where you look. I think some of
the gig-ethernets
use jumbo packets, then there is the 1500 byte or so regular mtu,
then there
is also possible modifications to the mtu depending on what the local
transport is (cable,
dsl, frame relay, etc).
I still check for max hops :-)

OK, I solved the problem(though I don't understand how it solved)

It does not help me here:(. I will get "Too Many Hops" (SIP
response 483),
it's something that seems to get my SIP message stuck in the first 2
routines.

I have the exact problem. I fixed by changing it to the following
instead:
if (msg:len >= max_len ) {
sl_send_reply("513", "Message too big");
return;
};

Subject: [Users] 513 Message too big
Hi,
I've exhausted my knowledge on openser:(. Following is my
openser.cfg which
is pretty much copy directly from sample but I kept getting "513
Message too
big" response from this server for SIP registration, I know the SIP
registration message size is ONLY 555 bytes, what could be wrong here?
Thanks in Advance!
