Bionet 2 ~~~~~~~~ Bionet 2 uses mDNS-SD (multicast DNS with Service Discovery) to find the peers on the network. In order for this to work, you need to be running the avahi-daemon on each host that will run HABs or Clients. To compile: autogen.sh ./configure make To see it do something: # in one shell: cd client/watcher ./bionet-watcher # in another shell: cd hab/random ./random-hab Known issues: Ubuntu 9.0.4 (Jaunty Jackalope): avahi-daemon does not work correctly in Ubuntu 9.04 (Jaunty Jackalope) and possibly other distributions due to misconfiguration. If the service discovery is not working or working inconsistently, edit /etc/default/avahi-daemon so that AVAHI_DAEMON_DETECT_LOCAL is set to 0. See Ubuntu bug #327362. ASN.1 Compiler: The ASN1c compiler has two known bugs affecting Bionet. 32-bit machines output an 'error converting ASN INTEGER to native Datapoint value' message when receiving a new-node message or a datapoint update message from a 64-bit machine if the message contains a uint32 resource with a value greater than or equal to 2^31. The new-node is still reported (with no known value for the resource), but the datapoint update is not. 32-bit machines will also output an error message (indicating that the server message 'contained an invalid ASN.1 message') if they receive a new-node or datapoint update message from a 64-bit machine if the message contains an int32 resource with a negative datapoint value. New-node and datapoint-update callbacks will not called. BDM-Sync w/ ION 1.1.0: As specified by RFC 5050, Bionet Data Manager sync sends bundles that represent logical application units, and under certain situations, BDM sync messages can be quite large. Since ION 1.1.0 baseline does not fragment or reassemble bundles, so care must be taken to ensure that the sync messages will fit in the maximum bundle size supported by the trasport being used. After calculating the maximum bundle size for the transport(s) in use, set the 'bunble_mtu' setting in the bdm-sync-sender-config Experimental Software: bionet-plot and bdmplot2 are in early development stages. They cannot yet handle overlapping subscriptions from multiple web clients.
