Hi, 

Sorry if somebody has already risen this but I just discovered that toolkit 3.4 doesn’t support non-standard OWAMP control ports and always uses the default value  861 even when some other port was specified in Add New Host  pane.  It can be seen in different ways: 

-  tcpdump shows that owamp requests go out with 861 instead of 888 in my case; 

- regular_testing.log has repeating OWPControlOpen(apus.carnet.hr): Couldn't open 'control' connection to server: Connection refused

- regular_testing.conf has no information about a OWAMP control port value at all. 

What’s more the web page of Add New Host allows to enter a non-standard OWAMP port value only initially but doesn’t have  afield for a port when I open it for editing the Test member parameters. 

At the same time owping –c 10 apus.carnet.hr:888 works without any problems, showing plausible data for both directions. 

I believe that after installation toolkit 3.4 didn’t have this problem, it appeared very recently, maybe last week (probably after some auto update?). 

Does anybody else use a non-standard owamp control port? 

Best, 

Victor
