I am trying to run a nessus scan from cronjob by subprocess python module. ,but from cronjob it's is giving an error. But not giving any error on execution of script from bash?
the cronjob code
01 11 * * * /root/nessusscan.py
and subprocess call in script is
subprocess.call(['nessus','-q','-x','-T','nessus','127.0.0.1','1241','user','password','ip.txt','res'])
from bash it's working fine but from cronjob i am getting following error in mail
Traceback (most recent call last):
File "/root/nessusscan.py", line 9, in <module>
subprocess.call(['nessus','-q','-x','-T','nessus','127.0.0.1','1241','user','password','ip.txt','res'])
File "/usr/lib/python2.7/subprocess.py", line 493, in call

errread, errwrite)
File "/usr/lib/python2.7/subprocess.py", line 1249, in _execute_child
raise child_exception
OSError: [Errno 13] Permission denied
Thnx to evry one i am answering my own question for other people who will vist this thread. So that they can also get out of this error. In my case error got solved by giving the path of nessus which is "/opt/nessus/bin/nessus"
replaced nessus with "/opt/nessus/bin/nessus"
cronjob was not able to get the path of nessus command.It's working now.

I have a Raspberry PI and I want to automatically open a website at boot time.
So I made an auto start config to run a python (v.3.5.3) script on boot.
The python script looks like this:
import os
import subprocess
subprocess.call([/home/pi/Desktop/Shortcut Final.desktop])
But I get the error:
Traceback (most recent call last): File "/home/pi/myscript.py", line 3
subprocess.call([/home/pi/Desktop/Shortcut Final.desktop])
^ SyntaxError: invalid syntax
I got my instructions from a guide that used windows file location, so I think the error is that my file location dont start with a directory letter like C:, but I dont think raspbian use the same system.
I have not found any other guides that explain how to accomplish the same thing in simple terms (as i only know very basic python coding)
I have looked into the open() command, but it seemed complicated.
Any tips on how to accomplish my goal/solve the error?
After putting the file location in quotes the syntax error disappears and i encounter a new error:

I am getting the following error while running gclient runhooks for building chromium.

In order to get permission of the directory "/usr/bin/python src/tools/clang/scripts" I tried chown and chmod but it returned the same error.
I think the python scripts in scripts directory are trying to modify some other files or directories .... try to trace what it is trying to do...... You have not specified the OS on which u are working ....... see this link https://github.com/aerospike/aerospike-client-python/issues/22
It says Linux Mint 17 is not supported officially.....
Actually the directory was not mounted with execution permission. So I remounted the directory with execution permission using
mount -o exec /dev/sda5 /media/usrname
and it worked fine.
I have a python script. On top of the script "from subprocess import call". If I write "call(["whoami"])" in the script and I execute the Python script from the unix command line it works, my username returns. But if I run a proprietary command with arguments, "call(["mi_xx", "-s", "20141215","-e","20150121","-p",'TX%_XX%',"-f","test","-i","-x","-d"])"
I get the error below. I run the same command directly in unix and it works. I have searched up and down. The python environment in unix is fine.

I have OSX and am running the python script out of the Unix shell
I'm running a python code that should open an application. I've been testing with Firefox.app and have been getting
Traceback (most recent call last):
File "/Users/brennan/Desktop/Coding/Wilix/wilix.py", line 453, in <module>
subprocess.call(["open -a "+cp2])
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/subprocess.py", line 493, in call

raise child_exception
OSError: [Errno 2] No such file or directory
My code is:
subprocess.call(["open -a "+cp2])
where cp2 is user input. (Firefox in this case)
if I cd into the programs directory and then do
open -a Firefox
firefox opens fine.
if I change my code to
subprocess.call(["open -a Firefox"])
I still get the error message.
You're passing open -a Firefox as one argument, as if you ran this in the shell:
$ "open -a Firefox"
You need to split up the items:
subprocess.call(['open', '-a', 'Firefox'])
Try giving the full path of firefox app.
It's wrong to use subprocess.call without shell=True or providing command as a list. Please, take a look at first examples in the docs:
http://docs.python.org/2/library/subprocess.html
Full path to Firefox may be needed or may be not needed.
I have written a script from the Python to automate scan. I have used nessus for that and used subprocess module in python. Problem is this it's running from the cli bash, but when I put that script to launch through by cron job. It gives following error
Traceback (most recent call last):
File "/root/nessusscan.py", line 9, in <module>
subprocess.call(['nessus','-q','-x','-T','nessus','127.0.0.1','1241','user','password','ip.txt','res'])
File "/usr/lib/python2.7/subprocess.py", line 493, in call
return Popen(*popenargs, **kwargs).wait()
File "/usr/lib/python2.7/subprocess.py", line 679, in __init__
errread, errwrite)
File "/usr/lib/python2.7/subprocess.py", line 1249, in _execute_child
raise child_exception
OSError: [Errno 13] Permission denied
The script is
subprocess.call(['nessus','-q','-x','-T','nessus','127.0.0.1','1241','user','password','ip.txt','res'])
Command for cron job
16 14 * * * cd /root/nessus; ./nessusscan.py
The error means that the program is found by subprocess but the user running the "nessusscan.py" does not have permissions to run it.
Check ownership of the nessus file and the permissions on it.
