Hi,
If any is familiar with pexpect, please help to point out why my script seems
to fail to capture the desired text.
Here, I want to log into a server 172.27.161.19. Once I see "Username: ", I
will type in my userid "admin".
The problem here is I have a list of keywords for pexpect to match before
returning the matched item for me. The list consists of following list items:
expects = ['yes', '.*Username: ', '.*login: |.*Login: ', 'SY-FAR-1>',
'SY-FAR-1#', 'Password: |password: ', '.*Press RETURN to get started']
Here, it seems my script found "Username: " but it got displayed as PART OF
_pexpect_session.after (and this is what I don't understand). The ".before"
or ".after" data should consist of match before and after the desired keyword
only.
============= Manual Execution =======================
telnet 172.27.161.19
Trying 172.27.161.19...
Connected to 172.27.161.19.
Escape character is '^]'.

Username: admin
Password:

SY-FAR-1#
=============== Python Script Snippet =======================
expects = ['yes', '.*Username: ', '.*login: |.*Login: ', 'SY-FAR-1>',
'SY-FAR-1#', 'Password: |password: ', '.*Press RETURN to get started']
i = -1 # reset its value
print "*step 1*before match, i = %s" % i
self._pexpect_session.timeout = 80
cmd = "admin"
self._log("Executing CLI: '{0}'".format(cmd))
self._pexpect_session.sendline(cmd)
i = self._pexpect_session.expect(expects)
print "*step 2* found index i = %s" % i
print "*step 3* after match, exec_cmd expects (%s) =" % i, expects
print "*step 4* exec_cmd match before: '%s'" %
self._pexpect_session.before
print "*step 5* exec_cmd match after: '%s'" %
self._pexpect_session.after
=============== Actual Script Output ======================
*step1* before match, i = -1
Executing CLI: 'admin'
*step2* found index i = 1
*step3* after match, exec_cmd expects (1) = ['yes', '.*Username: ', '.*login:
|.*Login: ', 'SY-FAR-1>', 'SY-FAR-1#', 'Password: |password: ', '.*Press RETURN
to get started']
*step4* exec_cmd match before: ''
*step5* exec_cmd match after: '
Username: '
Appreciate any input or explanation.
Thanks,
Viet
