Miki, 

Maybe a dumb question, but have you verified that the firewall rules either on the machine itself or along the way to the machine on your faculty network are allowing that port? You will need both the control port and the test ports allowed, which are typically 861 for control and 8760-9960 for testing.

A quick "telnet $yourhost 861" from home should reveal whether or not you are able to talk to the owampd process from home.

Greetings, 

I have some problems with owping and would appreciate some small help.

I have faculty project to test owping on RaspberryPi. I have owampd process started on computer on faculty network, and i managed to owping it RPi was also connected to that network. 

But, when i try to owping it from home, i get message:

owping: FILE=protocol.c, LINE=1758, _OWPReadStartAck: Unable to read from socket.

owping: FILE=owping.c, LINE=200, Session Failed!

To note, i have started ntp process, but i didn't connect clock source yet (like it is stated in manuals), because i think clock is needed only for better results. Or i am wrong?

Thanks for your time

Greetings
