Does any one know the process or commands to get the serial no: of a h/w device from a host?
I am looking for serial No: of Hdd,Graphic card,processor,RAM
I can get the serials of HDD & RAM using hdparm & dmidecode,but don't know how to get it for processor & Graphics card.
I used an execl call to dmidecode and parsed it using sed to get serial numbersso a business friend could make a (mostly) unique serial when his cross platform software is installed on different machines.I know this is falling outside the spirit of Linux being a profit thing, but the request has been to now do the same thing without using Linux commands. Which sounds like a chore since I would be re-inventing something that already exist namely dmidecode. Is the source available for dmidecode?I have no idea where to start to look for the info like dmidecode provides.

I have putty configured for 9600 baud, 8 bits, no parity, one stop bit, no flow control.I get the login prompt from agetty in the putty window but input does not work; I see weird characters in the putty screen. I can echo output into the device from windows and see it, but
cat < /dev/ttyS0. just prints out weird characters from what I type.
am writing a small search program for my class. I have decided to use indexing for my program. Ive researched online about indexing and how search engines do it. If im gonno do that I need to create inverted files to associate files to numbers ( numbers being the index of my paths ) . Now I was wondering what would be the best way to create an inverted file ? I was going to create sql tables using mysql api in C but then again there is no array data type or vectors to store few numbers in a single column in mysql and it is not advised to use Enum or SET
View 14 Replies View RelatedOn my CentOS 5.2 install I've installed a dual-port serial card based on the NetMOS 9835 chipset. I've followed the serial instructions, but everything they tell me to do is already done - see setserial outputs below. I've compared these values to the lspci output (below, NetMos card is at the bottom of the output) for the card and it appears right. Problem being, I can't use the serial ports. Oh and I did use search, and looked at every 9835-related article before posting this :)

I am hoping to be able to get an old serial-touchscreen to work with a usb/serial adapter. I had this touchscreen working some years ago on different hardware. I would like to hook it to the machine I am setting up as a multimedia host with mythtv among other things.
Following the instructions I left behind when I got this to work way back when does not work. See [URL] ....
This info is a work around to get the xserver to see the touchscreen. [URL] ....
I do know that the touchscreen works as I am able to get garbage on the screen as in the first part of my howto. But I have not had any success getting xorg to see it. I wish I had posted a copy of the xorg.conf at the time, but......
There is an issue with the current xserver in testing that I am hoping the next update (in unstable) will fix when it gets pushed to testing. That is that Code: Select all# X -configure fails with a segfault. So I am not able to generate the xorg.conf needed to get it to work. I was going to post a bugreport, that is when I found out there is an update in unstable, so I am waiting for it to get pushed at the moment.
Anyway I am hoping that I can link /dev/ttyUSB0 to /dev/tty0 and get it to work. I would like some kind of guess as to my chances of success before I go to all the work of getting the monitor hooked to the host.
I have two servers, one has an empty / and the other has a subdirectory with a large number (4 gig) with many, many files. I need a way to transfer the files en masse from the server with the large number of files to the one that is essentially blank.I don't have space on the used host to simply gzip all the files. I've googled this and see that there may be some combination of tar and/or gzip that will let me do this with some sort of redirection.
I really need and example line of how this can be accomplished. If my explanation seems rather sparse, I can supply more details.
I have a bit of a dilemma. I'm attempting to use a microcontroller to send MIDI messages over a virtual serial port. I want to (eventually) read them with Mixxx. I'm using an FTDI chip, so I get a /dev/ttyUSB0. I've tried spikenzielabs' Serial-Midi program, but it doesn't see any serial ports. NOTEMIDI looks really old and won't compile on my 10.04 LTS machine.

Firstly I would like to say that Linux is very cool, especially the CLI. I have been trying to learn how to do some things in Fedora after being told Fedora was a good distro to get my feet wet. I have run into some issues and cant seem to find any answers. What Linux utility can be configured to automatically save the current logs?
How does your Fedora get an IP number? What IP numbers has your Fedora been assigned since it was installed (based on the logs you have)? What command did you run to determine the IP numbers? What command would you run to determine the number of times a user successfully used "su"? What command would you run to determine the number of times a user unsuccessfully used "su"? Having some issues with the file system as your Fedora boots up.

If I cd to /etc and run ls *[0-9]* it almost works but it also includes results from within files. My last thought was to try: find /etc [0-9] -type f but this does not work either. My second problem is that I am trying to get list of files in a directory that were changed less than 10 hours ago, using grep, while leaving out directories. I am completely stuck with the second problem.

Create the file ~/license_counts, which tables the number of occurrences of packages which are licensed under a given license, for the top 5 most commonly used licenses, sorted in numerically descending order. If performed correctly, your file should be formatted similarly to the following. (Do not be concerned if the actual counts or license names are different. Also, you might notice logically similar licenses, such as LGPL/GPL and GPL/LGPL. Do not make any attempt to combine them into a single entry.)

I am using RHEL 5. In my Linux Box I have two Lan cards (eth0 and eth1). "eth0" is connected with network 192.168.10.0 and "eth1" is connected with network 192.168.11.0. Both Network are inter connected via routing. Now I want a situation where, I want to dedicatedly assign some port numbers against a lan card. Like eth0 will be assigned for ssh (22) and eth1 is assigned for telnet (23). So that, when a user connect to 22 port then he/she is connected to the server through eth0 , and when a user connect 23 port then he/she is connected to the server through eth1. Is it possible to do using iptables or other?
View 2 Replies View RelatedIs there a command to return a recursive listing of sub-directories and the number of files in them? I have found plenty of ways to give me the total number of files in a directory structure, but none that gives a list of the sub-directories with the number of files in them. "du" gives me a listing of directories with their sizes, but I couldn't find an option (or any other way) to give me the number of files as well. Ideally, I'd like to get list with "Size" "Files" "Dir name" - And the order of the columns doesn't matter. Is there a "simple" command line solution or do I need a shell script for that?
