Renaud, Thanks for the tip – I did just that – MAKEDEV a few more
bpf’s and recompiled the whole suite and it works fine. As I intend
to run a few nessus jobs through cron, is there some rule of thumbs
on how many BPF’s should be configured per concurrent nessus
process / host tested / concurrent pluggin? Many thanks once more
for the hand
To be safe, you should create 3x more bpfs than you intend to scan
hosts in parallel. (ie: if you want to scan 20 hosts in parallel,
create 60 bpfs). This is more than safe.
