Opz, I forgot to reply to maillist and instead sent private to ithilgore.

Yes, the output is like that:

However, if I open a parallel shell and I call ssh root@10.10.1.3 it
shows the SSH banner and in sequence ask for my password.

Any idea why?

Thanks

Hi,

I downloaded Nrack SNV release and Alpha-02 and both do not work
against my SSH servers. I tested against two SSH servers, a openSSH
and a CuteFTP sshd, both with SSHv2.

I can connect to both servers without problems without client, but
when I use ncrack, is just runs forever and never give at least a try,
the output is like that:

I'm  using like that:

ncrack -v -U common.usr -P default.pwd MyIP:22

Also, if I replace -U with "--user root" and -P with "--pass root" the
same happens.

Very wired. Is it a well known problem? There is a fix?

Thanks


I just tested the module against a latest OpenSSH server and it worked
fine. Could you also please provide some capture data (if any)?

Thanks,
ithilgore
