I run phc2sys like this on the master and the slave. I guess I don't really know how to run and what to run on each PC. My goal is to sync the system clock between both PCs, what do Ineed to do on each of them to do that?

Please show us the phc2sys output, with -m. For example, on my PC, I run ptp4l, and it locks to my GPS/PTP master with output like what you posted. Then, I start phc2sys, also on my PC, and I see: # ./phc2sys -m -q -r -a phc2sys[19289.292]: reconfiguring after port state change phc2sys[19289.293]: selecting CLOCK_REALTIME for synchronization phc2sys[19289.293]: selecting eth6 as the master clock phc2sys[19289.293]: phc offset 61893 s0 freq +11746 delay 5743 phc2sys[19290.293]: phc offset 61937 s1 freq +11790 delay 5698 phc2sys[19291.293]: phc offset 674 s2 freq +12464 delay 5574 phc2sys[19292.293]: phc offset 715 s2 freq +12707 delay 5694 phc2sys[19293.293]: phc offset -209 s2 freq +11998 delay 5748 phc2sys[19294.294]: phc offset -546 s2 freq +11598 delay 5575 phc2sys[19295.294]: phc offset 293 s2 freq +12273 delay 5758 phc2sys[19296.294]: phc offset 174 s2 freq +12242 delay 5719 and so on.
