Hi Adriel and Sebastien,

I think I know what is going on. We only set the destination IP when
it is present in the log itself. So, for
a sshd message like:

Apr 24 00:00:02 enigma sshd[10115]: Accepted publickey for xyz from
192.168.2.10 port 6427 ssh2

It would have no dstip. My suggestion (code-wise) would be to set the
Prelude target address to the
hostname or agent ip addresss.... What do you think?


Thanks,
