I have never set-up a chroot-jailed environment before and I am afraid I need some help to do it well.To explain shortly what this is all about: I have a webserver to which users send python scripts to process various files that are stored on the server (the system is for Research purpose).Everyday a cron job starts the execution of the uploaded scripts via a command of this kind: /usr/bin/python script_file.pyAll of this is really insecure and I would like to create a jail in which I would copy the necessary files (uploaded scripts, files to process, python binary and dependencies).
I already looked at various utilities to create jails but none of them seemed up-to-date or were lacking solid documentation (ie. the links proposed in How can I run an untrusted python script)Could anyone guide me to a viable solution to my problem? like a working example of a script that creates a jail, put some files in it and executes a python script?
Do you know how to write a shell script that executes say 4 instances of the same program in different directories at the same time, and once ONE instance completes it executes a new instance of that program in a new directoryd so on, until 100 instances have been executed, each in their own directory

View 8 Replies View RelatedI have a HP Pavilion dv7-2230sa During boot I get a series of errors about ACPI and AHCI Conflicts, the result of which I have to dissable ACPI with acpi=off. However when acpi=off my wireless Broadcom b43 series refuses to enable the wifi. I just can't press the button that would enable / dissable the wifi.
The wifi is detected, the drivers and firmware are installed, however the light remains firmly in the RED.the ethernet works, sound works fine, There also seems to be an issue with the ATi/Radeon Driver being missing which is causing fatal errors at boot time and also some memory conflicts again causing fatal errors.
I have tried this laptop under opensuse 11.2 and now under opensuse 11.3M5 without sucsess - however to my dislike Ubuntu have managed to resolve this by accident between 9.4 and 9.10 but i wanna use opensuse not ubuntu i have asked them to tell me how they fixed it to share it with you but I am still plowing my way through their forum!

Tired of installing ndiswrapper and everything to set up a wireless card? Try this!(might only work with Broadcom) Go to System > Administration > Additional Drivers. If you know the name of the brand of it (mine was Broadcom) it should come up. Install the driver. Tada! You've installed the driver simply!

I am trying to write a script to set the SGE job execution order. I named each job with 'job1', 'job2' and 'job3'. I want my script to do: When 'job1' execution is complete, 'job2' is executed; when both 'job1' and 'job2' are complete, 'job3' is executed.
First, I tried this following script and it worked well:
########
qsub -N job1 run1.sh # run1.sh includes "mv file_name1 file_name2"
qsub -N job2 -hold_jid job1 run2.sh # run2.sh includes "mv file_name2
file_name3"

We are on our first Linux platform and I am trying to coordinate a distributed application backup across multiple machines. I am trying to write a script in which I would have used RSH to execute scripts on the other servers. We are no longer allowed to use rsh, and someone suggested ssh. I am using that instead of telnet, but I am not sure of the syntax"rsh server [-n] path/executable" is what I would have used, just not sure of the syntax for ssh
View 8 Replies View RelatedI'm not sure if this is a Debian-specific question or a KDE question.
FYI:
uname -a
Linux DESKTOP 3.16.0-4-686-pae #1 SMP Debian 3.16.7-ckt11-1+deb8u3 (2015-08-04) i686 GNU/Linux
(Running KDE).
Question:
Upon logging in (typically, for the first time each day) I would like to see a console window/shell or a simple terminal-emulator/shell automatically open up.
The reason is: In order to get my .bashrc to execute I have to log-in, then bring up an xterm or some other terminal-emulator.
Background: My .bashrc has a once-per-day routine/section that will set up my desktop to look the way I want it on my initial log-in (primarily with my Java applications up/running and displayed and waiting for me).
Then, later on that day whenever I bring up new bash shells, my .bashrc is executed but that once-per-day routine/section is no longer executed.
what i need is to execute a script before reboot actualy the system reboot faster than the script execute how can we force the system to wait for the script complete execution
its for my 11g database [URL]
I have been trying to get my development box up and running and I decided to do some CGI work in Perl and I am getting a 500 error on Apache 2. I have checked all the perl settings and the script runs fine on the CLI. I am simply passing a textfield from a HTML form to Perl. I was using the standard CGI.pm calls but I modified the script just to use print statements to make the output page. The script has one textfield in it, as it was just supposed to test the CGI.
I have the UserDir directive active for my user and I did some modifications to allow CGI execution from my home directory /public_html/cgi-bin/. the script will not run from the main /var/www/cgi-bin directory either,that also returns a 500 error. the permissions are 755 on both copies of the script in the cgi-bin directories.
I need to find out the processing or operating time in milliseconds or in nanoseconds for the instructions or for the whole process!
for eg :
I need to calculate the time taken to execute :
And i dont want the time for whole program :
I have seen command like $rm aa dd cc bb ee then something like $ >> zz // it removes zz also Where aa dd cc bb ee zz are the files in my directory. Do not know exactly.

I have a file named "test.txt". It contains the following:
Hello $USER1
Your boss is $ADMIN1
Now, I want to do something like this:
export USER1="World"
export ADMIN1="Me"
cat test.txt > test2.txt
And achieve something like this when I view the contents of test2.txt:
Hello World
Your boss is Me
The problem is, it's not that easy to achieve. I don't want to do the "echo Hello $USER1 >> test2.txt" because I'm planning to implement this on a MB-sized text file.
I'm trying to save the output of the script I wanna run but for some reason I cant manage to do it with "script.sh > Output_4.txt"
The thing is that the script was already run and it extracted some directories so when I try to run it again (to save the log to a Output_4.txt) bash says (see screen-capture) and of course the log's empty!!!!
Now my script is able to start server, But I am still have some problem with my script. When the start server command is executed, the control does not pass the line and does not execute further of that line.what is the problem and how can I get smooth execution of the my script. My Script:
SUBIT="su - adminuser -c "
SERVER_BOX_COMMAND_A="Server"

In bash shell, is there a simple way for me to monitor the time taken to run a script and output the time taken?
View 1 Replies View RelatedProblem started after installing a new firewall in my network. originally after installing the firewall there would be a 10 second delay after entering a command before it was processed, the command would be executed however there would be an error, i forget what it said, something about not being able to resolve my domain name (and it would give my domain name). i realized this was a problem with my NAT, so i configured DNS forwarding on my firewall so that any attempt to access my server using my domain name from inside the network would point back at my server. after setting up the DNS forwarding i no longer receive the error about my domain name being unreachable, however there is approximately a 30s delay between entering a command and its execution.
the problem is hardly critical i do not see any more serious problems, it is just a pain to do any work when every time i try to do something i have to wait for it to execute.
How do I create a command to launch a program and then have the terminal wait for a specified time and then move on to the next command?I'm wanting to create a startup script, and I need program B to wait until program A has finished loading up.

I want to make sure all users should use scheduler for job submission and should not submit the job directly ( qsub job.sh ).
I want to prevent all users from executing executable files created by self , from its home directory .
Suppose if a user create an executable a.out and if he tries to execute by ./a.out it should display an error.We should also allow users to execute normal user level linux commands .How can I implement such a set up in my environment
