    Default ncrack + ssh = "Invalid service module: ssh"

    just as the title says

    I think this is a backtrack 5 KDE4 64bit bug? ncrack + BT4R2 worked just fine. talking with others on #backtrack-linux on freenode this isn't a problem with GNOME.

    Code:
    # ncrack -v --user mysql 192.168.xx.xxx:22

    Invalid service module: ssh
    QUITTING!
    /usr/local/share/ncrack/ncrack-services
    shows that ssh on port 22 is there ::
    Code:
    ssh 22/tcp
    -fnord0

    now, while the above is a bug... I figure I might as well throw in the request for ncrack RDP, VNC and SMB capabilities, as those do not work either (RDP specifically would be great!).
    in the meantime I just grabbed ncrack from svn and compiled it myself, yet I look forward to official support from the backtrack repo.

    thanks for everything ya'all do! hopefully this get's read and acted upon, if you (backtrack dev team) would like, I'd be more then happy to post this request in the "Tools Request" forum....

    I was unable to duplicate this error. BT5 KDE 64-bit VM with Windows 7 host OS. (target IP address masked for obvious reasons)

    root@bt:~# ncrack -v --user mysql xx.xx.xx.xx:22

    Updated with upgrade #14.

    apt-get update
    apt-get upgrade

    or

    apt-get update
    apt-get install ncrack

    Same error here on gnome 32 but only when attacking locally

    Code:
     ncrack -vv --user root 192.168.0.9:22

    If I attack my external ip the attack works fine...

    Code:
    ncrack -vv --user root 72.193.224.55:22

    Notice it doesn't crack anything but that's only because the service isn't forwarded to begin with.

    u backtrack devs are on top o' things, this is great! ncrack + ssh is working perfect now in BT5 KDE64 - also seeing that SMB, RDP and VNC are available. gotta love it! thanks x1000 muts
