Solaris 下pxssh模块应用，求指导

seacnboy

代码如下：
#!/usr/bin/env python
# -*- coding: utf-8 -*-

import pxssh,os
def nasssh(nas_ip):
    cmd =['cluster show','system stat sys']
    s=pxssh.pxssh()
    uesrname='sa'
    password='god'
    s.login(nas_ip,uesrname,password)
    s.prompt()
    print 'normal login'
    for i in cmd:
        s.sendline(i)
        s.prompt()
    print  s.before
    s.sendline('logout')
    s.prompt()
    print s.before
    print 'normal exit'
nasssh('192.168.100.4')

错误信息：
当把cmd里的指令执行完毕后，报错如下：
oss5nas> system stat sys

不懂，帮顶

编辑“/usr/lib/python2.6/site-packages/pexpect/__init__.py”，将“ raise EOF(str(err) + '\n' + str(self))”这段代码注释掉，程序正常运行。。
