Nimbostratususe pool member problem and weird universal persistence error
I have two separate issues but both are related to solving the same problem:
I have the code:
set node [session lookup universal $hexid]
log "found node $node in session table"
use pool socks member $node
This doesn't seem to direct connections to the node that is found with session lookup. I get the output:
Rule adam_socks_ssl_persist : found node 172.20.20.1 in session table
Rule adam_socks_ssl_persist : Connected to backend server 172.20.20.2
This is consistent.
If I use the "node" command instead of "use pool" then I *do* get sent to the same node every time. This "works" except that it won't send the client anywhere if it doesn't already have a session. If there is session information already it persists properly.
set node [session lookup universal $hexid]
log "found node $node in session table"
node $node
Rule adam_socks_ssl_persist : found node 172.20.20.3 in session table
Rule adam_socks_ssl_persist : Connected to backend server 172.20.20.3
Adam_Kramer_150I figured out my other issue before I finished the post - when I was using "node" instead of "use pool" I was getting this error when trying to set the session again later in SERVER_DATA:
TCL error: Rule adam_socks_ssl_persist - Prerequisite operation not in progress (line 1) invoked from within "session add universal $hexid [IP::remote_addr]"
I'm pretty sure that's because the default session add adds to the "pool" session but there isn't exactly a pool selected when you choose a node directly.
