Oh - you have a local owserver querying another owserver on a different machine! My owfs.conf only has server: w1 in that position. bus.0/bus.0/interface/settings address W1 bus monitor name W1 monitor bus.0/bus.1/interface/settings address w1_bus_master1 name w1 > So I had > > /bus.0/interface/settings/name -> LinkHub-E v1.1 > /bus.0/interface/settings/address -> /dev/ttyS0 > /bus.1/interface/settings/name -> tcp > /bus.1/interface/settings/address -> > some.fully.qualified.domain.name:4304 > (note the bus.0 and bus.1 thing.)

I know from Wireshark that the BBB is not hitting my network router with any DNS requests during the speed test. No idea what it might be doing internally. But I don't even have "localhost" involved, definitely not any non-numeric addresses. > IMHO your config should be: > > ! server: server = localhost:4304 > server: server = config for your bus masters > server: port = 4304 Mine was like that, except the second one said server: port = localhost:4304 Maybe that was the only problem? Netstat showed owserver as 127.0.0.1:4304, and I could not access it from other machines out on the network. After I changed to ! server: server = 10.1.1.4:4304 and server: port = 4304 netstat showed it as 0.0.0.0:4304, and I could reach it from outside. > (localhost does no harm if you have the '127.0.0.1 localhost? line in > /etc/hosts, and ?hosts: files dns? in /etc/nsswitch.conf, which should be > the default.) I believe I have those: --- ubuntu@arm:~$ cat /etc/hosts 127.0.0.1 localhost 127.0.1.1 arm ubuntu@arm:~$ cat /etc/nsswitch.conf # /etc/nsswitch.conf # # Example configuration of GNU Name Service Switch functionality. # If you have the `glibc-doc-reference' and `info' packages installed, try: # `info libc "Name Service Switch"' for information about this file. passwd: compat group: compat shadow: compat hosts: files mdns4_minimal [NOTFOUND=return] dns networks: files protocols: db files services: db files ethers: db files rpc: db files netgroup: nis --- Always more to learn, Loren | Loren Amelang | lo...@pacific.net | ------------------------------------------------------------------------------ _______________________________________________ Owfs-developers mailing list Owfs-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/owfs-developers
