expectによる入力の自動化

次のようなファイルを作っておいて、./ssh.exp 192.168.251.154　などとやるとパスワードを自動入力してssh接続が可能。

#!/usr/bin/expect

set RemoteHost [lindex $argv 0]
set PW "programming"
#set PW [lindex $argv 1]
set Prompt "\[#$%>\]"

set timeout 5

spawn env LANG=C /usr/bin/ssh -o StrictHostKeyChecking=no -l training ${RemoteHost}
expect {
    -glob "(yes/no)?" {
        send "yes\n"
        exp_continue
    }
    -glob "password:" {
        send -- "${PW}\n"
    }
}

expect {
    -glob "${Prompt}" {
        interact
        exit 0
    }
}

ssh先でコマンドを実行して終わる場合は

#!/usr/bin/expect

set PW "programming"
set RemoteHost [lindex $argv 0]
#set PW [lindex $argv 1]
set Prompt "\[#$%>\]"

set timeout 5

spawn env LANG=C /usr/bin/ssh -o StrictHostKeyChecking=no -l training ${RemoteHost}
expect {
    -glob "(yes/no)?" {
        send "yes\n"
        exp_continue
    }
    -glob "password:" {
        send -- "${PW}\n"
    }
}

expect {
    -glob "${Prompt}" {
        log_user 0
        send "date\n"
        send "gsettings set org.gnome.desktop.session idle-delay 0\n"
    }
}

expect {
    -regexp "\n.*\n" {
        log_user 1
        send "exit\n"
        exit 0
    }
}
