View 1 Replies View RelatedIn order to get internet access at my school I have to log into a vpn. No other addresses can be accessed before login. With XP the login is authenticated through the browser (IE and Firefox supported) and run by a juniper network connect applet.
Now when I try to do this in firefox in Ubuntu it tells me that I'm not allowed to login. So I started doing a little research and found out that I should be able to authenticate with VPNC. Trouble is I can't get internet to install anything. Which means I have to download the packages in XP and reboot into Ubuntu. And every time I hit a snag I have to reboot into XP to look up what I need to do. So what I'm wondering is if there is some work around that will get me logged in (maybe through the browser authentication?) so that I can work through issues in one os instead of two?
The command cat /proc/PID/maps shows the memory map (virtual addresses) of the process. How these address are actually mapped?

I am new to Linux kernel/user space programming having been an assembly programmer in my previous life. I am now using 2.6.x kernel on an embedded CPU that has a few dedicated hardware blocks (including more CPU running just C-code, i.e., no operating system). There is a single DRAM connected to this chip with one Linux CPU + multiple h/w blocks. No swapping.Question(s):
1. The Linux CPU needs to talk to hardware blocks that obviously physical DRAM addresses while Linux processes/threads use virtual addresses.
2. How do I translate these addresses back-n-forth? For example, a Linux process may want to allocate memory and then hand it off to a hardware block to write into it. Then after a while the process will read it.
3. Sometimes, the hardware block may write a physical address into the shared memory. The Linux CPU will read the shared memory and then convert the physical address to virtual memory and go read that location.
How does one achieve all of this? If this is being extremely stupid, then please let me know. Hopefully, you can give me some pointers.
I get errors trying to virtual IPv6 Addresses i a lab environment. It works fine up to 2033 (?) adrressses, but when I try to add more i get "Cannot allocate memory" error:

This is on Ubuntu Server 9.10 (64-bit).
I have two networks on a server. One being my internal network, and the other being an external IP address. This is on Debian Lenny. Here is my /etc/network/interfaces file:
I can reboot my system and sometimes eth1 is accessible from SSH, and other times eth0 is accessible. Then sometimes eth1 will just stop being pingable alltogether. This is a fairly fresh install of Debian, and the only thing I have running is VMWare Server 2.0, bridged to both of my network connections.
Here is what my route looks like:
How would I find out all the files a particular process accesses?
I am using Ubuntu 9.04.
With the find command it is easy to find files that have been modified or accessed within a given period. When a file is created, the acesss time is the same as the modify time. But as soon it is accessed (read), the access time changes, but the modify time does not. I need to find files that been accessed at all, ie. files which have access time newer than modify time. How do I do that?

View 1 Replies View RelatedI 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

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?
In bash shell, is there a simple way for me to monitor the time taken to run a script and output the time taken?

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
how I can receive emails about a cronjob execution or where to go to read about that? I am using CentOS 5.4.
