How to get the list of virtual addresses being accessed by any application during its execution time. I don't want the complete memory map but just the pages which were accessed during an application's execution?

View 2 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?

When i am trying to access the any directory other on port *80, its not being accessible from the static ip which is routed through a DMZ server. http://122.165.35.9:8085 something like this returns the error "could not connect to web browser"
now I have managed my rsyslogd to log the firewall into a separate file I would like to use a script which looks into this file for intruders which for example try to ping, telnet, ssh, rdp etc into my dsl connection.And then use a kind of app or firewall on my ubuntu server to block them.Yes my firewall logs them but does not block them if the policy is enabled, so they have access on through the firewall and the connect to my server but I only want some known IP addresses have access through it and this I cannot program in the firewall so I have to use some extras.Or am I thinking way to far and is there a better solution with IPtables or app?Is it possible to watch tcp connections between the firewall from outside IP addresses and the ubuntu server?
View 7 Replies View RelatedI 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 am using malloc and frees a lot in my program. It shows its allocated but when i remove it doesnt show as the memory is removed(I am using the top command to view VIRT memory usage). If this continously grows what would happen to my program (Will it go out of memory?)

P.S. I use 'spice' option of KVM.
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:

View 1 Replies View Relatedconcerning controlling the windows in virtual desktop.
a) Say to a application to be launched to virtual desktop 2 for example.
b) How can you ask from a virtual application to be only visible at one virtual desktop. For example I work on virtual desktop 6 and I want to start skype that should be on virtual desktop 2. Right now If I launch the app on virtual desktop 6 it will appear on the same one. Would it be possible to ask for an applicaiton to be launched on an other virtual desktop. If yew how?
I need to run an application on a virtual desktop (let say desktop #2) and control it via another app running on the root desktop (desktop #1). That would include screen capture and mouse movements. So basically I capture the application window from desktop #2, scrape it and then click on buttons via my app on desktop #1. Anyway you got the idea.Now my big question is: is that doable ? and if so what's the best language to do it ?
View 1 Replies View RelatedHow 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?

First, I tried this following script and it worked well:

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?
