NimbostratusCommand returned bad code: 12 while executing
Hi
we're "playing" with this iRule:
when SERVER_CONNECTED {
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]
}
}
to manage the tftp secure connections but sometimes we get this error message:
Nov 2 23:55:17 tmm tmm[1678]: 01220001:3: TCL error: iRule_TFTP_VoIP - command returned bad code: 12
while executing
"listen {
proto 17
timeout 60
bind [LINK::vlan_id] [IP::local_addr] [peer {UDP::client_port}]
server [peer {IP::client_addr}] [..."
where could I track for some information ¿?
Thank you in advanced.
- 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.

Angel_Martinez_Thank you I'll give you my improve!- Angel_Martinez_good! ;o) it gives me a clue!
ndecaris_66201what 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 ?
