While you can  help Waldo, here i think you bring a bit of confusion
to the thread.


The initial question from Balla is, why event 1 is considered as
blocked while the other is not considered as blocked.

While both events have the same src ip dest ip src port dest port.

My wild guess would be that its because it could be triggering of the
same packet and the engine only block once
but alert twice, but to be sure mabey Balla should provide a pcap file
with his configuration that lead to the generation
of those events and mabey someone @sf could answer better at this point.

i'm asking what a blocked entry looks like in the /raw/ unified2 log file...
that is the key to figuring out and understanding why it is being shown by
u2spewfoo as a block...

Blocked is a unified2 structure field and its part of every unified2 event type,
its set by the engine, thus u2spewfoo does not makeup "block", its
only displaying it.


correct... i do not think that is normal snort output... it is what u2spewfoo
has output...

See above waldo.




should logged events look different?

not if you are using u2spewfoo, AFAIK...

See above also.
