View 8 Replies View RelatedI have Ubuntu 10.04 LTS. I have a script that prompts you to insert a USB HDD/memory stick then it needs to determine its serial and model and save it to a file. The script can determine the device file of the inserted drive(ex: /dev/sdc) and if hdparm -I /dev/sdc works then all is ok. The problem is that not all USB HDDs/memory sticks work with hdparm. When it does not work I get the following:
Code:
root@izghitu:~# hdparm -I /dev/sdc
/dev/sdc:
HDIO_DRIVE_CMD(identify) failed: Invalid exchange
The other command to get the serial for USB devices of any kind is lsusb -v or lsusb -D /path/to/bus/address The problem of the first one(lsusb -v) is that it lists all USB devices and there's no way for me to script it to detect the inserted USB drive/memory stick and get the serial/model for it. The problem with the second one(lsusb -D /path/to/bus/address) is that I do not know how to get the correct USB bus address of the inserted USB drive/memory stick.
Is there any other way to get the serial number/model of a USB HDD/memory stick using its /dev/sdc device file? Is there any way to link the /dev/sdc device file with the /dev/bus/usb/address device file so I can then use the lsusb -D command to get the required info?
Kernel 2.6.21.5, Slackware 12.0
Code:
root@darkstar:~# blkid
/dev/sda: LABEL="MAESTRO!" UUID="4730-D359" TYPE="vfat"
/dev/hdc: LABEL="STORE1 ver. 2 (overrules ver. 1)" TYPE="iso9660"
[code]...
As you can see, the first command gives numbers like C841-0655. But for the optical disks (iso9660) it gives them not. Neither does the second one. This number is known as 'Volume serial number' in MS-DOS, and is printed on console with the command 'dir' not only for the HDD partitions but for the optical disks too. how to get an optical disk Volume serial number? Notice that this number is inherent to the media (is a property of the media, under any O.S.).
how do i get the volume serial number using the API on CentOS?for example, on Microsoft Windows i use this function(API - Kernel32.dll):
BOOL GetVolumeInformation One of function's parameter is a pointer to a variable that receive the volume serial number;
I want to get the Hard Disk serial number of SCSI HDD on Solaris. On linux this is done using following structs and API:
struct hd_driveid hd;
int ide;
ide=open("/dev/hda",O_RDONLY);
(void)ioctl(ide,HDIO_GET_IDENTITY,&hd);
(void)printf("Serial number - %s
",hd.serial_no);
Is there any similar method exists in Solaris to get HDD serial number.

Code:
V:>dir
Volume in drive V is AppDrive
Volume Serial Number is 8CD5-975C
...and all Win7 computers get a diffrent one:
Code:
V:>dir
Volume in drive V is AppDrive
Volume Serial Number is A0D3-975C
We use application witch somehow only works when one/same volume serial number on a mounted drive is used.

I am new to Linux ,i did one project in windows which will block the thumb drive with respect to serial number(Device instance ID) of the device.i am planning to do the same project in Linux using c/c++.I am very new to Linux,there is no drive letter for thumb drives we insert into Linux OS.How to get Drive letter and how to get Device instance id of thumb drives please help me get some clues.please provide me any tutorial or any links .w if have any other clues to block devices with respect "block list" and "allow device list".if the serial number in block list it has to block if serial number in allow device list it has to allow thumb drive to access.
View 3 Replies View RelatedI am trying to get two way serial communications going between a Windows XP system and a Linux system (RHEL 5).I have /sbin/agetty -L 9600 ttyS0
in /etc/inittab. I am using a generic USB to serial adaptor on Windows (Unitek) and a null modem cable. 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.
On 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 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.

How to find out server's HDD Serial no tried below command but didnt work,
#hdparm -I /dev/sda
so please help & Thanks in Advance.
I've got a home server running ubuntu 10.0.4. It have no monitor or keyboard. So I want to access it from a serial console. (I use SSH currently but if something goes wrong, I need to be able to do something... so serial console seems a fine thing). OK, so on the server, I tell grub to output everything on ttyS0 and opened a getty on ttyS0. On the client side (Laptop running Ubuntu 10.0.4 with pl2303 USB to Serial adapter) I use Minicom.
Home server restart:I see grub menu, linux kernel messages, login prompt. But, I can't do anything:In grub or at the login prompt, no key press is recognized by the server.I've got write permission to /dev/ttyUSB0. I tried a different getty (mgetty)with no success.I stopped the getty on ttyS0 on the server. And run minicom.
From the server's minicom, if I type something, it appear on the client screen. From the client's minicom, if I type something, some garbage appear on the server screen :(One of this things for each char typed). If I short-circuit pin 2 and 3 of the client serial port, it echoed what I type. The two serial ports are connected with a nullmodem cable. (seems to be a full handshaking cable). Of course, same serial port config for both minicom, grub and getty. Hope I'm understandable enough. (English not my primary language). Can somebody help me make this *$*#! serial console working right ? I'm on it for 10 hours now with no success...
Edit : I nearly forgot to tell you I had to update the standard ubuntu kernel to 2.6.34-020634rc1-generic because there was a bug in the pl2303 driver in the stock kernel (2.6.32-25-generic) which prevented me from doing anything (even receiving).
I am wanting to set-up serial communications between my server (ubuntu 9.04) and a picaxe chip (a pic with a bootloader) I need to send data in the format of "1,1,1" or "1,1,0" at 9600 baud 8 data bits, no parity, 1 stop bit and no flow control. the data must be sent as numbers not ASCII I have tried
Code:
echo 1,1,0 > /dev/ttyS0
Any simple shell script or even python.
We have an APC UPS connected to our main server via a serial cable, with the APC Powerchute Business Edition up and running nicely. We also have another server which is protected by the same UPS I started looking at an APC interface expander which would allow shutdown of multiple servers from the same UPS, however it appears it's not standard serial cables but a whole proprietory nightmare.possible to hook both servers up with a serial cable and have the master shut the other one down through a shell script? Both boxes are CentOS 5.4

Here's a little tool that does this:
Without arguments, updates the SOA serial in a zonefile to the current date. If the date was already updated, just updates the revision number (incrementing up to 99, and then again 01). Uses RFC 1912* recommended format.
With $1 == <two digit number>, auto updates (if necessary) just the date part and uses your provided revision number.
With $1 == <eight digit number>, uses that as a date (no validation of any kind), and just auto update the revision number
With $1 == <full serial>, will just replace whatever the serial is with the provided serial, without any validation
* YYYYMMDDRR (4-digit year, 2-digit month, 2-digit day of month, 2-digit revision number)
This script + keeping SOA/NS/MX/CNAME RRs in a common file $included from other files with $ORIGIN and A/PTR/TXT RRs, made everything way easier to manage, enabling me to script some zone switchers, automatic failover/redirection of DNS on WAN changes, etc, etc. I think this stuff might be cool to integrate with something like this script and make nice CLI toolset for bind. Looking forward to implement it.
Code in pastebin
Code:
#!/bin/bash
# globals
script_name="${0##*/}"
script_dir=$(readlink -f "${0%/*}")
script_version=1 .....
I'm working on program that is going through setting different baud rates onto a config file. After I set a new value i want to check if it's the correct one by reading from the serial port on the server unit. I know what to expect if it's the correct baud rate so that's no problem, but searching through the internett i've yet to find a compact solution to my problem.
