Hi,

I am trying to run offline analysis using bro on pcap files.

I created local.bro as

redef local\_nets: set[subnet] = {  
a.b.c.d/24,  
};

@load brolite  
@load brolite-sigs

Then I am trying to use

bro -r trace1.tcpdump local.bro

but giving me errors like this

/usr/local/bro//policy/local.bro, line 1 (local\_nets): error, “redef” used but not previously defined

What can I do to overcome this error.

Thanks in advance.

Try putting the redef after the @load commands - it needs to be defined in the @load'ed scripts before it can be redef'd.

Hope this helps.
