I’ve installed Bro from tar.gz with :

Ubuntu@Ubuntu:~/bro-2.4.1$ ./configure --prefix=/opt/bro --logdir=/var/log/bro
Ubuntu@Ubuntu:~/bro-2.4.1$ make

Ubuntu@Ubuntu:~/bro-2.4.1$ sudo make install

And my conf is :
networks.cfg
W.W.W.W/24 Private IP space
Y.Y.Y.Y/24 Private IP space

nodes.cfg
[bro]
type=standalone
host=localhost
interface=eth1

Thank you for your help,

Regards,

Maxime Lambert

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.

Hi Daniel,

That's :
[BroControl] > nodes
            bro - addr=::1 aux_scripts= brobase= count=1 env_vars= ether= host=localhost interface=eth1 lb_interfaces= lb_method= lb_procs= name=bro pin_cpus= test_mykey= type=standalone zone_id=

And :
[BroControl] > status
Getting process status ...
Getting peer status ...
Name Type Host Status Pid Peers Started
bro standalone localhost stopped

Best regards,

Maxime Lambert

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

Hi everyone,

Mistake, from my interface !

And thanks to sudo LANG= /opt/bro/bin/broctl all is OK !

Thanks you very much !

Best regards,

Maxime Lambert
