pexpect - logging input AND output

Show all headers | View raw

i have a script running a few commands on a network device. i can't seem to figure out how to log both the input and output of what the pexpect script initiates and responds to.

child = pexpect.spawn ('telnet '+ ip)
child.expect ('.*:*')
child.sendline (user)
child.expect ('.*:*')
child.sendline (password)
child.expect(['.*#*', '.*>*'])
child.sendline ('enable')
child.expect (['Password:', '.*#*'])
child.sendline (password)
child.expect ('.*#*')
child.sendline ('conf t')
child.expect ('.*#*')
child.sendline ('line vty 0 4')

i have tried both these logging commands:

child.logfile = open('log.txt', 'w')
child.logfile=sys.stdout

all i get is the input i send with expect/sendline combinations, i don't get any of what the device sends, only what i send the device:

user
password
enable
password
conf t
line vty 0 4

any ideas of what is the correct way to go about this? just can't get the output!
