ssh script

[ub007]

Hi,

I have scripted this code to ssh into my remote server and log back some info.

import sys, os, re, optparse, traceback, types, time, getpass
import pexpect, pxssh
import readline, atexit

begin = time.time()
os.system('nc -l 2222 > log%s &' %begin)
time.sleep(50)
child = pexpect.spawn ('ssh david@192.168.0.14')
child.expect ('password:')
child.sendline ('mypass')
child.expect ('$')
child.sendline ('df |nc 192.168.0.14 2222')
child.sendline ('exit')
child.sendline ('exit')

However each time I get 0byte files logged.
eg

0 Nov 3 11:15 log1288782916.15

No when I do the same stuff manually:
local machine

nc -l 2222 > log &

Then ssh into remote server & do

df |nc 192.168.0.14 2222

it works

2880 Nov 3 11:27 log

I do a strace on nc ( launched from script )

shutdown(4, 0 /* receive */) = -1 ENOTCONN (Transport endpoint is not connected)

Any thoughts guys?

Thanks in advance

David

oopss, theres a typo.
child.sendline ('df |nc 192.168.0.18 2222').
