In BroControl, what is the output of the "nodes" command? Also, what is the output of the "status" command? ---

Did you try unsetting the LANG variable? sudo LANG= /opt/bro/bin/broctl (mind the blank after the "=".) Best regards, Sven ---

This issue was fixed a long time ago, but I just remembered that the fix was not included in the Bro 2.4.1 release. It will be included in the next release, however. ---

You have 'interface=eth1' in your node.cfg but you don't actually have an eth1 interface. ---
