Yes, I tried that (didn't seem to make any difference). I also started with a fresh copy of the sources: $ git clone --recursive ssh://git@git.bro-ids.org/bro $ grep -R listen\_port\_clear bro bro/aux/broctl/BroControl/install.py: print \>\>out, "redef Communication::listen\_port\_clear = %s/tcp;" % nextPort(manager) After building and installing Bro, I did this: $ broctl [BroControl] \> install [BroControl] \> start starting bro ... bro terminated immediately after starting; check output with "diag" [BroControl] \> diag ==== stderr.log error in /myprefix/spool/policy/auto/standalone-layout.bro, line 2: "redef" used but not previously defined (Communication::listen\_port\_clear) ---
