   * If it does not read ''​waiting for connection'',​ it should give the IP address of the machine that's currently talking to it (e.g if it reads ''​Command from 131.217.63.201:''​ then the connection is from 131.217.63.201). You can lookup up the name of this machine using ''​nslookup 131.217.63.201''​ - in this example it is the ''​hobart''​ machine that is talking with the DBBC. If a PCFS machine is connected, the best option is to terminate the FS on that machine and restart with a version that will not conflict. For the Hobart example, running ''​fs-auscope''​ will avoid this problem while ''​fs-flexbuff''​ will block communications. ​   * If it does not read ''​waiting for connection'',​ it should give the IP address of the machine that's currently talking to it (e.g if it reads ''​Command from 131.217.63.201:''​ then the connection is from 131.217.63.201).

   * You can make a test recording to check for synchrnoisation problems between the different DBBCs with ''​~/​bin/​sxtimetest.sh''​ which will print out the decoded time of the start of the test recording. All three values should agree and match the time reported in the FS log for when the "​record=on"​ command was issued. If the times differ between the different datastreams,​ you will need to reconfigure the relevant DBBCs. If they are all in agreement but differ from the FS log, please note this difference in the log but proceed on to the next step.    * You can make a test recording to check for synchrnoisation problems between the different DBBCs with ''​~/​bin/​sxtimetest.sh''​ which will print out the decoded time of the start of the test recording.
