Re: [Jack-Devel] connecting jack between a linux audio master and a windows slave

it sounded like so indeed, unfortunately disabling the virtualbox-host
interface still did not resolve the issue.
I am using 'tcpdump' on the *jack master* to listen for udp packets on port
19000 (where jack broadcasts by default). the cmd is:
tcpdump host <ip_of_jackd_client> and udp port 19000
In turn I checked some linux clients and the windows client:

linux cl1 (ip 192.168.112.133 - name jackcl1)
16:10:39.532802 IP jackcl1.19000 > jack_master.58548: UDP, length 44
16:10:39.533960 IP jack_master.58548 > jackcl1.19000: UDP, length 1500
16:10:39.533970 IP jack_master.58548 > jackcl1.19000: UDP, length 204

linux client 2 (ip 192.168.112.144 - name jackcl2) looks similar
16:23:09.842778 IP jackcl2.19000 > jack_master.54735: UDP, length 204
16:23:09.842782 IP jackcl2.19000 > jack_master.54735: UDP, length 564
16:23:09.843880 IP jack_master.54735 > jackcl2.19000: UDP, length 1500
16:23:09.843890 IP jack_master.54735 > jackcl2.19000: UDP, length 204


unfortunately it looks like the windows jack client sends out the packets,
but the jack master never responds...
16:11:52.040582 IP wincl1.19000 > jack_master.19000: UDP, length 644
16:11:53.528440 IP wincl1.19000 > jack_master.19000: UDP, length 644
16:11:55.028455 IP wincl1.19000 > jack_master.19000: UDP, length 644

can you make anything out of that? Is there a max number of jack clients
that can be connected in a jack server and now the jack server does not
respond?
currently I have 9 readable & writable clients, each of which has 2-12
input & output ports respectively....
