I need to execute an external command with Python from Web. I know there is subprocess module that executes external programs but I'm trying to execute a command registered for the execution of a program. In this case when I execute my file in the shell everything is Ok, but from the Web it doesn't work.
View 1 RepliesI want to be able to do
sudo ./program.py
instead of always having to do
sudo python program.py
What do I need to change?
what we are trying to do is, to let the customer click a button in the web browser, and then the web server to call a shell script to do the work. The output from the stdout && stderr of the script should be displayed in the web browser once finished or timeout, along with the exit code of the script.
The shell script is however not on the web server, but on another app server. So to call this script from the web server as the identity 'tomcat':
Code:
$ sh appuser@app-server:$appbin/app-script
The .ssh/id_rsa.pub thing is done, and we have no problem doing this in the command line so far.
Our loaded ex-colleage has left us the webpages (jsp) with code like these:
Code:
<%@ include file="jsp_functions.jsp" %>
<%
String cmd = "sh $appbin/app-script";
ExecResult r = new ExecResult();

I've writte a small Munin plugin using python, which basically runs a shell command, and write the output to a file. For some reason the script fail quite often, and it seems to be failing at the "commands.getoutput" statement. This is what's leading up to that statement:

An example of one command I'm trying to execute is: Runtime.getRuntime.exec("rm file_name"); -> This commands outputs that I don't have permissions.
If I add "su" before the command, how do I add the password?

I have a dual boot Dell Studio laptop with Windows (VISTA) and Ubuntu (9.0.4) installed on it. I have recently installed Ubuntu to make it a dual boot. Before that I was using LiveUSB Ubuntu image for six months (without any problems).
During the installation of Ubuntu, I created a Linux partition of 2GB for Ubuntu installation (assuming that it was running successfully on my 2GB USB drive). All of my other work (e.g. documents/programming projects etc.) are stored on the Windows partition (which is loaded during the boot time automatically). The problem is that I get a "permission denied" error while running any executable file on the Windows partition. But if I copy the same executable on the Linux partition, everything works perfect. Am I missing something here?
I have verified that the executable have necessary execute permissions.
I have a function definition in a Python 2.x script which take a tuple as one of its arguments, but 2to3 has no answers nor any of my searching on how to represent the same in Python 3.x

I have a some c source code files that i have to copy to linux machine from a windows machine over a network. This source code folder has to be copied into a particular directory structure in the linux system at the other end. After copying the file into the appropriate folder in the linux server i have to instruct the linux machine to make(using the make file that is there with the c files) this source code from the windows machine. Does anyone have any idea in regard to how this can be implemented?? i am trying to have a gui client that has the above mentioned options(copying and inserting the c files into the appropriate directory and then for making the files and getting the executable.)
View 3 Replies View Relatedim searching for this answer now a pretty long time and i know that many similar questions where asked and i all looked themIm trying to run a the command "vncserver" on our opensuse11.2 server when its booted.many posts here endet in "put a sh script into your /kde4/Autostart" but that didtn help for me because the server runs without a screen and normally nobody is logged in. When i logged in that worked fine.i also tried to add the command "vncserver" to "/etc/init.d/boot.local " but that didnt work too. i think its to early executed to work.i also tried to activate the service to start up at boot with chkconfig vncserver start but the service vncserver is "unknown". when i type vncserver into the console after logging in everything is alright.you see i really tried a lot and searched a long time at google and in this forum but nothing worked

ssh -Y user@machine 'firefox &'
I ssh into the remote machine as the named user and pop an instance of firefox from that machine back to my own. If I put the same thing into a shell script though, it fails.

ssh -Y user@machine 'firefox &'
I'm just left sitting at a command line on the remote machine. Why does the script fail and how can I make it work?
I have the following command:ssh $USER@$HOST "ls /ops/pkg/ec/`grep "PKRTS" /ops/pkg/ec | awk '{print $1}'`* > /tmp/tmp_file"What the above SHOULD do..is, ssh to the host then execute the command.The command should first execute the grep and awk between the back ticks, and generate a file name, then ls using that filename* and write that data to a temp file.However, it executes the grep and awk before even SSH'ing and the command that goes to the server is simply an "ls /ops/pkg/ec/* > /tmp/tmp_file" since the grep and awk return nothing on the local machine.

View 5 Replies View RelatedI have a php file that I need to execute via a cronjob. This file should be run by the www-data user as its a file in my /var/www/project folder. When I run this file under root (php -f cron.php) everything works perfectly, but I want it to run under the www-data to be safe. Before I run it vai crontab I tried it via command line as the www-data user and I receive errors:
Fatal Error: Allowed memory size of 8388608 bytes expired (tried to allocate 232 bytes).
But when I run it as the root user I get no errors and everything works correctly. The file cron.php is used to process automated tasks in my CRM. So I don't really want to have the root user running a crontab every few minutes for this.
Must the www-data user be given more permissions? I am using Ubuntu 6.06LTS
PHP - 5.1.2
Apache - 2.0.55
MySQL - 5.0.22
I was just curious if cron had to be enabled before use. i have a crontab, and the cron daemon is running, but the command isn't executing...
