UDP iRule question

If I want to have an iRule for UDP data that will distribute based on a string that is in the first 50 bytes, this simple iRule should do it right?     when CLIENT_ACCEPTED { UDP::collect 50 } ...

Hi,

 

 

I'm getting errors when trying to use UDP::payload inside SERVER_CONNECTED.

 

I've got the following error :

 

--

 

Nov 2 12:00:40 tmm tmm[26896]: 01220001:3: TCL error: Rule rad_p2 - More data required (line 1) invoked from within "{UDP::payload}"

 

--

 

 

This is the code part where the error happens :

 

 

 

when SERVER_CONNECTED {

 

if {[UDP::remote_port] eq 1813} {

 

log local0. "rulerule sss -- [LB::server addr] ";

 

set ip1 0; set ip2 0; set ip3 0; set ip4 0;

 

binary scan [{UDP::payload}] c* str;

 

...

 

 

Does anyone know why this is happening, I noticed already that it is working in CLIENT_ACCEPTED.. but then I don't know to which node the data will go.. And that is also something that I need to know.

 

 

Thanks,

 

Jeroen
