Linux dynamic library and static C++ data

Hi All, I am new to linux. I have a doubt. Here is my question: I have a class named "shrd" like this: class shrd { public: static int i; }; I have it in a dynamic library. I load the library from two process A and B. If I change the variable in process A, will it be visible in process B? I tried this in windows and its not the case. But one of my friend working on linux tells that it happens in Linux. If it happens like this my question is, why is there a need for shared memory? or inter process communication? Please let me know, and also let me know where I can read in detail

Is dd's data filtered by the appropriate devicedriver?

It seems that `dd` is a massively powerful yet simple utility. It can read/write any device/file -- or ? So does that mean that <how to access the device> is determined by the particular <device driver> ? So then, instead of going via C, could one use a bash script to eg. Write a sequence of bytes to a USB-device, WHILE reading the USB-device's reaction, either by existing <access USB> utilities, or by `dd' UNTIL the USB-device shows a certain 'state'; thereby discovering what byte/s are needed to mode-switch a USB zeroCD device ? Or how can a bash-scri

Thumb Drive: Is my stuff gone?

I did some work on a Windows XP Pro Service Pack 2 box in another city a few weeks ago. I thought I copied over a *.zip file onto my thumb drive. Today, on Linux box, the latest Ubuntu, I plugged the thumb drive in. No files were displayed and the listing for the directory said that 0 memory was being used. I'm guessing I didn't copy or save properly, but is it possible this might be a file format issue of some kind? If so what can I try to see that file? Thanks in advance either way

Linux & Streaming Netflix ?

I have a netflix account. I have the latest version of Ubuntu. I'm guessing the answer is "no", but I was wondering if anyone has come up with anything that would allow a linux user to watch streaming content from Netflix? Thanks in advance either way.

How to save (not download) a streaming video to disk?

When I'd like to download a flash movie from youtube I just use the Firefox add-on FlashGot and it works. But on some sites FlashGot can't find an URL which (as far as I know) it needs to download a video. So these sites only stream the flash video (which I can watch real-time in my browser) and download is no option, right? Can I redirect this video stream and save it in a video file without any loss of quality? I googled this a lot and did many tests. I found out that vlc has streaming capabilities. But vlc also needs an URL to work. What about ffmpeg? The man page reads it

How do list all crontabs for ALL users? Can crond run without a crontab?

Assume I login into a Linux system with user "karl". When I enter in a Terminal: crontab -l then only the crontab resp. the cronjobs are listed which run under the user "karl". Even when I switch to user root I get only the cronjobs for user root. How do I list ALL cronjobs for ALL users on the current system? Another question: Can "crond" run WITHOUT a cronjob file assigned to it? reason: When I enter "crontab -l" then I got no output although ps -A|grep cron shows a line: 2901 ? 00:00:00 crond Peter

any major RedHat sprogs besides Fedora + Centos?

The last 3 companies I worked for used Centos. Computer magazines often include Fedora in the free DVD. I have seen lists of other Redhat derivatives, but the names mean little to me, apart from Whitebox (which is no more updated). So are there other significant distros in this clan?

HOW2 map <usb> to '/dev/*'

When I do: lsusb I get: Bus 001 Device 001: ID 0000:0000 Bus 001 Device 003: ID 12d1:1010 Which gives me the info to do: modprobe usbserial vendor=0x12d1 product=0x1010 for the second listed device, listed as "Bus 001 Device 003". I want to read and write to this device. Perhaps via `dd` or cat /dev/xyz or echo "ATZ" > /dev/xyz So then I'd have to mount the device, first. I've tried to examine the 'most recent' /dev/* to see which is associated with the device that's detected by lsusb. --- And when I unplug & plug the usb-device to another usb-socket, I get

System not usable after a "could not getpeername" error

Hello, we have a old 2.4.19-64GB-SMP server ( we can not change it at the moment ) . Today it freezed twice and we had to reboot via sysreq. In /var/log/messages I found Aug 27 17:22:08 galileo2 -- MARK -- Aug 27 17:38:01 galileo2 inetd[1397]: could not getpeername Aug 27 17:38:08 galileo2 inetd[1397]: could not getpeername Aug 27 17:39:34 galileo2 last message repeated 2 times Can anyone please tell me what could be the reason for this error and why it makes unusable the machine ?

Reserving blocks without actually creating files

Hello, Is it possible to mark blocks on a filesystem as used without actually putting anything into those blocks? It is like creating a sparse file but actually putting all the blocks aside. We have serious hanging issues with raids (sometimes 2-3 minutes). Here is a thread which pretty well describes the issue: http://www.linuxquestions.org/questions/linux-general-1/mkdir-slow-743424/ Our problem is that this hanging usually happens with big raids (5-10TB) and when the filesystem is nearly full, so testing different raid settings (and everything else) is very time intensive.

wrapper to automate uninstallation of programs that use make files

I keep coming across programs that have a "install" target but none for "uninstall" or "remove". This is fairly inconvinient when the time does come to get rid of the package. Of course, oftentimes the "install" does generate a log of sorts that I could manually use to remove files and dirs at a later date. e.g. see below. But are there any automated solutions or wrappers to target this problem? Ideally something that could track the changes "make install" made so that an unroll action is available at a later date. Also, some of these actions aren't that easy to unroll.

ZeroCD mystery

Please correct my assumed 'algorithm' for how the [for M$ convenience] ZeroCD devices work. This is about PCs/x86. Booting from any device happens simply by the BIOS pre-setting booting from the device which then, after its boot procedure is done, hands over to the OS. Is it true that ZeroCD relies on M$-Win's facility to automatically run the executable which it detects when a CDROM is plugged-in while the OS is already running? Is it true that this absurd facility allows people to spread virus by merely 'dropping some pre-loaded USB-stiks in the car park? Does M$-Win? ha

HOW2 find all recent files containing ALL N strings: google-like

One of the most useful, but missing utilities for me is one to: find that file of last week/month <about XYZ> which would probably have used the phrases/strings: "rep" "ulti" "tring". Well I just tested it to find the files related to this Newsgroup query which I made, and which just got a lot of kiddies guesses. I too don't really understand exactly how `xargs` works, but here's my substantially tested script for 3 strings, which I can easily edit for N strings *ALL* to be contained in the found-file/S:------- #!/bin/bash echo "list files ?days? old containing 3 strings= 4

tools to parse and expand ranges for bash

I use a parallel ssh tool (pssh) to run foo_command on multiple servers: pssh -h ~/hosts_file [more options] foo_command Unfortunately, it is built to require a hosts_file but cannot work with dynamic ranges. Host file has one-server-per-line which I must make each time I use it. Like so: server001 server002 server003 etc. It'd be convinient to be able to invoke it with servername ranges at times. e.g. (1) pssh -h <(server 1-15) foo_command (2) pssh -h <(server 1,3,35-42) foo_command etc. I'm wondering of the best strategy. One option: I write a bash script c

sizing a window upon startup?

I have /usr/lib/xscreensaver/sonar that I would like to open in a window, providing several options using a simple wrapper script. The window however is too small, and I'd like to open the app. in a full-screen window, but ask for help please in specifying X options to do so. "-geometry XxY" and --fullscreen fail, as they are not recognized options by sonar, nor does the "--" option terminator seem to work as expected. Ubuntu 10.04 Gnome desktop.

ip address to world location mapping tool?

Does anyone know of a tool that could graphically map the "registered" location of a group of IP addresses or their resolved names? I can extract the unique addresses from a various logfiles and would like to be able to plot those locations on a world map for presentation purposes. One supposes some recursion into whois o get such locations, but I assume that a Perl, Python or other such tool already exists somewhere for the task. Of course those locations will only be an approximation of the registrar's. Thanks for any help you might offer.

Re: HOW2 search/grep multiple strings ?

*MULTIPLE* strings are not *alternative* strings. Perhaps you need to think beyond just using ready made utilities? Various contibutors guessed at: 1> egrep -l "dog\|cat\|fish" {} 2> find . -exec egrep -l "\(dog\|cat\|fish\)" {} \; 3> grep -l -e dog -e cat -e fish * 4> find . -exec egrep -l "(dog|cat|fish)" {} 4> find . -exec grep -l "\(dog\|cat\|fish\)" {} 4> find . -exec grep -l -e dog -e cat -e fish {} AFAIK grep looks at 1 line at a time. The algorithm [which I've done in ETH-oberon] needs to: FOR QualifingFile DO CHECK for EACH/ALL strings. You might want

mdadm (SW-RAID) and RAID6 performance. Or should I use HW-RAID?

Are there any users using mdadm for RAID6? I wanted to get a performance estimate. Usually for RAID0,1,5 etc. I prefer well-tested, open-source mdadm to some sort of hardware implemented proprietary RAID card. But I've read that the checksum computation for RAID6 is computationally expensive. Hence I was wondering if it would be foolhardy to attempt a RAID6 via software-RAID. Or maybe not? It's going to be a disk-to-disk backup storage so performance is not super critical but I don't want to end up with something that crawls either. In case I am forced to go with a hardware
