I am having problems using cron to run a pexpect script on Solaris 10 that will ssh to other devices. The devices I am connecting to are networking elements which will accept ssh connections using user/pass (but I cannot reconfigure them).
I have this script that works fine when I run from a login shell but it fails when run from cron. I have read posts on setting the env to simulate an interactive shell but to no avail. Any help much appreciated. I am limited to using python 2.6, pexpect, Solaris 10.
Script is: /path_to/try.py
#!/usr/bin/env python
import pexpect
import traceback
import os, sys, time, re
from time import sleep
host='10.0.0.58'
user='myuser'
password='password'
child=pexpect.spawn("/usr/bin/ssh -l %s %s" % (user, host))
i = child.expect([pexpect.EOF, pexpect.TIMEOUT, "password: "])
if i == 0:
print "EOF ERROR SSH could not login %s . Here is what SSH said:"% (host)
print child.before, child.after
if i == 1: # Timeout
print "TIMEOUT ERROR SSH could not login. Here is what SSH said:" % (host)
print child.before, child.after
if i == 2:
child.sendline(password)
print "Got device password prompt"
print "finally"
exit;
crontab is:
42 * * * * PATH=$PATH:/usr/local/bin && bash -lc "/path_to/try.py"
Result from script via cron i.e.:
EOF ERROR SSH could not login 10.0.0.58 . Here is what SSH said:
