    ssh: connect to host localhost port 22: Connection refused


    i am on windows-64 bit hp machne.
    i installed first latest cygwin(from local directory) to run hadoop on windows,but forgot to install tcp_wrappers pacakge.
    so i deleted everything in C drive related to cygwin,also .ssh folder & .bashrc.profile
    & installed again cygwin freshly.

    i follow this tutorial:-http://v-lad.org/Tutorials/Hadoop/00%20-%20Intro.html
    & run below command (u can see this commands in snapshot)

    go to the "enviroment variables" (right click on computer-->properties-->advance .. -->enviroment variables)
    click on "new" button: name="CYGWIN" value="ntsec tty"
    then: start-->service.msc-->right click on cygwin service and start
    now run blow command:
    ssh-host-config -y



    i'm working on hadoop too, i'll be happy if we could share our information, if you agree with me just mail to:
