That's the Unix domain socket, the two instances need to have a
different path set by the uds_address option.
Here is an example with two interfaces, each in two PTP domains, the
first domain with HW timestamping, the other with SW timestamping.
There are four ptp4l instances and two phc2sys instances feeding four
SHM refclocks.
# cat timemaster.conf
[ntp_server 192.168.100.1]
[ptp_domain 0]

[ptp_domain 1]
