That's something that could be easily implemented. We can note that down
for
our TODO list.


Very good, it will be very helpful.


Ncrack already supports attacking multiple targets at the same time,
without
needing any particular command-line option. Just specify the hosts and
services/ports
you want, the way you do it with Nmap.


Ok, but I'm brute forcing only SSHv2. How should I for example tell to
Ncrack test 3, 4 of 5 SSH servers in parallel ? I'm reading the SSH servers
from a list with -iL.



And using Ncrack with -v it works, however if we use -vv or -vvv (more
verbose) it doesn't brute force, it shows the help again. Maybe a bug?

Yes, that is most likely a bug. I'll look into it.


Thanks.


You can do that interactively by pressing 'v' while Ncrack runs and it
will display
more output (or press 'V' to decrease it). It is more or less similar to
the way Nmap
works as far as interactive output is concerned. 'd' and 'D' also apply
for more/less
debugging output.


Nice workaround. I will try it.


Indeed, implementing the OpenSSH library for Ncrack [1] has many
advantages, but
as I said above, attacking several targets at once is an inherent
capability of
Ncrack. You can even attack different services (e.g a SSH service of one
host, and a FTP
service of another host) at the same time. See the man page for some
examples.


I saw that on documentation.

Thanks for help.




That's all.

Very nice tool.

Thank you.

Cheers,
