我有CSV文件中的文件conatainning像列aranged IPS：
10.38.227.233,VLAN-A,23
10.38.227.233,VLAN-XYZ,27
10.38.227.233,VLAN-XZ,27
10,38.169.103,VLAN-ABCD,11
10,38.169.103,VLAN-ABCD,16
10,38.169.103,VLAN-ABD,17
等等
对于每个IP I需要登录到Cisco开关和执行IP 10.38.227.233某些命令（VLAN-A，23 | VLAN-XYZ，27 | VLAN-XZ，27）
所有的IPS有超过从文件中相同的IPS密码，所以我想获得密码提示只有一次，循环。
我是新手，在这一点，并已经开始喜欢这个，但似乎并不工作。 现在，我通过在远程的* nix机器上执行简单的LS开始一些测试，但它不工作
#!/usr/bin/python
import pexpect
import getpass
import time
iplist = ['10.39.5.41', '10.38.164.103', '10.38.227.229']
for ip in iplist:
sshCmd = "ssh " + "auto21" + "@" + ip
#auto21 is a username
print "Command: " + sshCmd + "\n"
answer = 'yes/no'
prompt = 'password:'
password = getpass.getpass('password:')
#Sends answer based on target server response / known host
p = pexpect.spawn(sshCmd)
i = p.expect([answer, prompt])
print i
if i==0:
print 'Sending yes...'
p.sendline('yes')
p.expect(prompt)
print 'Sending password...'
p.sendline(password)
p.sendline('ls\r')
p.expect(pexpect.EOF,timeout=20)
print p.before,p.after
if i==1:
print 'Sending password...'
p.sendline(password)
p.sendline(password)
p.sendline('ls\r')
p.expect(pexpect.EOF)
try:
p.interact()
sys.exit(0)
except:
sys.exit(1)
这就是我得到：
bash-3.00# python ip.py
Command: ssh auto21@10.39.5.41
password:
1
Sending password...

请帮忙
此外我如何遍历文件中的IPS和执行一些集的ssh范围的命令。
注 ：每个IP将有多个VLAN，但每个VLAN将只有一个ID（如11,12）
编辑 ：我需要运行SSH范围的一些命令
ssh username@hosname "config t
int VLAN-A
switchport access VLAN-A 23
wr
#then for next VLAN for the current ip
config t
int VLAN-A
switchport access VLAN-A 23
wr
#and so on...............
"
