python and Pxssh

[jhon masco]

hi,
I am using pxssh for SSH connection in Python. [here the example http://www.pythonforbeginners.com/code-snippets-source-code/ssh-connection-with-python
It work fine for me when i connect to a remote Unix machine with prompt "$". My problem is that now i need to connect a server with different prompt, specifically it use 2 prompts. I want to send the prompt manually but nothing work.
I read the documentation and explain some ways to do something similar but its not working for me.! They don't have an example. For example in the next code:

import pxssh
s = pxssh.pxssh()
if not s.login ('localhost', 'myusername', 'mypassword'):
    print "SSH session failed on login."
    print str(s)
else:
    print "SSH session login successful"
    s.sendline ('uptime')
    s.prompt()         # match the prompt
    print s.before     # print everything before the prompt.
    s.logout()

I did the these changes:

import pxssh
s = pxssh.pxssh()
if not s.login ('mi IP', 'Usuario', 'mi password', auto_prompt_reset=False):
    print "SSH session failed on login."
    print str(s)
else:
    print "SSH session login successful"
    s.PROMPT='>'
    s.sendline ('mml')
    s.prompt()         
    print s.before    
 
    s.PROMPT='<'
    s.sendline ('comandoX')
    s.prompt()         
    print s.before  
    s.logout()

What is wrong?
Also i modify the "pxssh.py" the lines:

self.UNIQUE_PROMPT = "\[PEXPECT\][\<\>\$\#] "
def login (self,server,username,password='',terminal_type='ansi',original_prompt=r"[><#$]",login_timeout=10,port=None,auto_prompt_reset=False,ssh_key=None,quiet=True,sync_multiplier=1,check_local_ip=True):

In modified "original_prompt=r"[#$]" for "original_prompt=r"[><#$]"
and
self.UNIQUE_PROMPT = "\[PEXPECT\][\$\#] " for self.UNIQUE_PROMPT = "\[PEXPECT\][\<\>\$\#] "

Thanks

So what is it doing that you don't expect?
Have you checked all the return values and exceptions to see if you can figure out what exactly is failing? Looking at the documentation, I would assume the regular expression you are using for PROMPT is faulty. What is the prompt on the remote system if you log in with ssh?

Hi, I received this exception:

File "/home/jhon/PYTHON/pssh.py", line 6, in <module>
if not s.login ('172.31.116.167', 'usuario', 'mi_password', auto_prompt_reset=False):
File "/usr/lib/python2.7/dist-packages/pexpect/pxssh.py", line 315, in login
raise ExceptionPxssh ('could not synchronize with original prompt')
pexpect.pxssh.ExceptionPxssh: could not synchronize with original prompt

The prompt that i need to set is ">" and "<" below an output example:

c:\winnt\profiles\TRAFICO>mml
WO 63 03015103 AD-638 TIME 150128 0856 PAGE 1
<exit;

c:\winnt\profiles\TRAFICO>

I figure that there is a stranger character before the prompt but i am not sure if it relevant.
The documentation in the login meth section explain how set diferent prompt but its not working for me.

Thanks
