  • ...just be forewarned this greatly increases mapping time, especially if you're doing a /24 or bigger block. :)

  • hey, didn't pay attention to which version of nmap you were using, but you can skip the netcat step by nmap -PN -p22 -A TARGET_IP

    (the -PN, previously known as -P0, is "don't send ping probes to target(s)" is useful in case the target has ICMP traffic firewalled off. it does a service discovery (which is fingerprinted by the -A option, which is why netcat wouldn't be needed) on the host and target port(s) without assuming it's up/down based on ping response...)

  • lol, not very persistant are we? Well I tried twice, it can't be done. Time to go home. HAHA

  • Unhackable? No, you just didn't guess the damn password. Not unhackable, just idiot proof.

  • "unhackable" is quite a strong call to make. While the server will boot you off after a certain number of attempts, the attacker can still simply reconnect and try again - such measures only slow an attacker down.

    If you really want to prevent brute forcing, use a firewall that features blacklisting after a certain number of connection attempts.  OpenBSD's pf is ideal for this and there are guides on how to perform this kind of blacklisting - jfgi.

  • what is nc command ?
