Command returned bad code: 12 while executing

The short answer is that "code: 12" means that the address you're trying to listen on is already in use (there is already something on that IP/port tuple).

If you want to get more info on runtime TCL errors, you can use catch (Click here) to handle the error gracefully and log details on the problem:

 

 

catch {log local0. "\[LINK::vlan_id\]: [LINK::vlan_id], \[IP::local_addr\]: [IP::local_addr], \[peer \{UDP::client_port\}\]: [peer {UDP::client_port}], \[peer \{IP::client_addr\}\]: [peer {IP::client_addr}], \[peer \{UDP::client_port\}\]: [peer {UDP::client_port}], \[IP::server_addr\]: [IP::server_addr]"}

 

 

if {[catch {

 

listen {

 

proto 17

 

timeout 60

 

bind [LINK::vlan_id] [IP::local_addr] [peer {UDP::client_port}]

 

server [peer {IP::client_addr}] [peer {UDP::client_port}]

 

allow [IP::server_addr]

 

}

 

} result]}{

 

log local0. "Error: $result"

 

} else {

 

log local0. "Success: $result"

 

}

 

 

You might need to adjust the line breaks or escape them in the second catch statement, but hopefully you get the general idea.

Thank you I'll give you my improve!

good! ;o) it gives me a clue!

what is the clue ? i've the same problem ! the fact is that simultaneous client may have the same UDP port client.

 

 

i think you have to randomize the listening port for backend server : how does it write in the irule language ?
