pxssh批量登录报错，求帮助【已解决】
本帖最后由 _breeze_ 于 2015-01-05 10:35 编辑代码如下：
============================
#!/usr/bin/env python
import re
import os
import sys
import smtplib
import pxssh
import getpass
from email.mime.text import MIMEText
li=[]
sender = 'root@localhost.localdomain'
receivers = ['xx@qq.com']
s = pxssh.pxssh()
ip = ['192.168.85.225','192.168.18.222']
for i in ip:
try:
username = 'root'
print i
s.login(i,username,"")
s.sendline('cat /proc/mounts')
s.prompt()
f = s.before
s.sendline('ls /OTS')
s.sendline('exit')
s.prompt()
s.logout()
flag = 0
r = re.compile(r'((2\d|25|?\d\d?)\.){3}(2\d|25|?\d\d?)',re.I)
for line in f.split("\n"):
if r.match(line):
remount = line.split(" ")
localmount = line.split(" ")
flag+=1
if flag > 0:
pass
else:
li.append(i)
except pxssh.ExceptionPxssh,e:
print "pxssh faild on login."
print str(e)
if li:
messages= '%s NFSClient down' %li
smtpObj = smtplib.SMTP('localhost')
smtpObj.sendmail(sender,receivers,messages)
else:
pass
=============================
已经做了ssh信任，运行之后报错如下：
=======================================
Traceback (most recent call last):
File "./1007_NFSCheck.py", line 19, in <module>
s.login(i,username,"")
File "/usr/local/python2.7/lib/python2.7/site-packages/pexpect/pxssh.py", line 263, in login
spawn._spawn(self, cmd)
File "/usr/local/python2.7/lib/python2.7/site-packages/pexpect/__init__.py", line 622, in _spawn
assert self.pid is None, 'The pid member must be None.'
AssertionError: The pid member must be None.
s = pxssh.pxssh() 这句应放在 try内， ，自己写代码不严谨 .....
