paramiko 具體就不多說，看其他資料
yum insatll python-devel
1.PyCrypto安裝
tar -xf pycrypto-2.6.1.tar.gz cd pycrypto-2.6.1/ python setup.py build && python setup.py install
2.ecdsa安裝
unzip python-ecdsa-master.zip cd python-ecdsa-master python setup.py install
3.paramiko安裝
unzip paramiko-master.zip cd paramiko-master python setup.py build && python setup.py install
4.錯誤：
>>> import paramiko
/usr/lib64/python2.6/site-packages/Crypto/Util/number.py:57: PowmInsecureWarning: Not using mpz_powm_sec. You should rebuild using libgmp >= 5 to avoid timing attack vulnerability.
_warn("Not using mpz_powm_sec. You should rebuild using libgmp >= 5 to avoid timing attack vulnerability.", PowmInsecureWarning)
>>> exit()解決：
tar -xf gmp-5.1.1.tar.bz2 cd gmp-5.1.1 ./configure make make install yum remove gmp
5.簡單多進程：

2.txt 是一個列表文件
內容如下：
10.1.1.1 10.1.1.2 10.1.1.3 ....
通過進程池poll批量操作，控制同時運行的進程processes=30
