Debian :: Assigning A Device At Boot To /video2
Jan 29, 2011
I'm using Debian kernel 2.6.32-5-amd64 I have this little nit picky problem when I re-boot, my webcam and my Tv card switch around on video0, video1 and video2 if my usb webcam is plugged in at boot. I would like to keep it plugged in all the time and have it on video2 and my TV card on video0 and video1. I had read where maybe setting up a udev rule might accomplish what I want to do I just don't understand how.
Here is my camera info from lsusb:
Bus 004 Device 002: ID 046d:08d7 Logitech, Inc. QuickCam Communicate STX
Using v4l2ucp gives me this info about my hauppauge hvr1800 TV card:
Driver cx23885
card Hauppauge WinTV-HVR1800
bus_info PCIe:0000:03:00.0
capabilities 0x05010011

I have to do a project on network security.For that i have to capture the packets from the device. I installed libpcap tool in ubuntu. If I give ifconfig -a it lists out eth0, wlan0, lo. I am able to connect to the internet via eth0. But when I give
#include <stdio.h>
#include <pcap.h>
int main()
{
char *dev, errbuf[PCAP_ERRBUF_SIZE];
[Code]...
It says device is null. I'm not able to run sniffex.c program also. All I want to do is to capture the live network level packets and analyse them.

Reboot and select proper boot device or insert boot media in selected boot device and press a key. I got this error after: Reducing my Windows 7 partition by about 100gb. Creating a new partition (100gb) and copying my Ubuntu partition (10gb) to the new partition. After it was copied, and pasted, the original partition was deleted. I now had two partitions a new 100gb Ubuntu partition and a 600gb (or so) Windows 7 partition.
All of this was done using a bootable USB with Ubuntu 10.10 and GParted partition editor. Now when I boot I get the "Reboot and select proper boot device or insert boot media in selected boot device and press a key." error.

I'm wanting my ubuntu setup to 'get' it's IP details during bootup, i.e. before login.
This is so that I can logon via NX from my laptop without having to logon via the ubuntu machine first.

Without going into a lot of the reasons, I have a bootable program on a USB stick that i would like to 'boot' when debian is starting up (or after it completes, or whenever it makes sense to do it). My MB does not support a USB boot, I've removed the floppy and CD so I can add additional HDs (its a small box but well ventilated).
Another option I have is to use my bios 'network boot' option, but I have no clue how to use it and the only description in the mb manual says "Allows system to be booted over a network" In network boots, *usually* one is given an option of specifying a device address, and the network boot executes a boot protocol (e.g. bootp), and the boot image file is downloaded to the target, stored and run out of RAM. No evidence of this behavior is exhibited when the network boot option is selected in the bios...

I am running Raspbian, on my Raspberry Pi I have plugged in a Ethernet cable : eth0 and a Wifi Usb Dongle : wlan0
I have my etc/network/interfaces file configured like so
Code: Select allauto lo
iface lo inet loopback
iface eth0 inet dhcp
iface eth0 inet static
address 192.168.1.100
netmask 255.255.255.0
gateway 192.168.1.1
[Code] .....
When trying to connect with SSH to address 192.168.1.100, I get a connection, when trying with address 192.168.2.200, SSH returns Network Error: Connection timed out.
Also receive no response when trying to ping 192.168.2.200 from a windows machine
If however Iadjust the wlan0 block in etc/network/interfaces to the following
Code: Select alliface wlan0 inet static
address 192.168.1.200
netmask 255.255.255.0
I am able to connect to wlan0 in SSH to address 192.168.1.200, and I also receive requests when ping 192.168.1.200 from a windows machine. How can I use a different subnet for my wlan0 iface...

I am trying to figure out what needs to be done to automatically set read/write permissions for everyone for my proprietary USB device on system boot. I have created a udev rules file which changes the permissions for the device when it is connected, but it does not change the permissions when the system is booted with the device already connected. The file looks like this:
SUBSYSTEM=="usb_device", SYSFS{idVendor}=="our vendor id", MODE="0666"
Does something else need to be added to the rules file to make it work when the system boots with the device connected? Is there some other script which needs to be created somewhere?

I JUST registered here as I have not used Linux in several months. Linux and I have been and off and on relationship, but after I realized Ubuntus limitations Ive pretty much only dealt only with Debian (on PPC as well as x86, and also some Suse on x86).
Anyway, so I just picked up a couple Sun Ultra 5s for free. One had 256MB RAM (4 x 64MB), a 4.3GB IDE HD (no SCSI in the Ultra 5), and booted fine in Solaris up to the login screen at which point it wasnt really any use to me since I dont know the login name or password, and really want to run Linux anyway. The other I am told needed a firmware (chip?) and basically didnt do much more than power on. However, it had a 40GB HD and 2 x 128MB RAM modules. So, I replaced the 4.3GB drive with the 40GB, and replaced 2 of the 64MB RAM modules with 2 128MB modules, for a total of 384MB RAM.
BTW, both machines have the 270MHz Ultra1 CPU. Anyway, I used my main Windows x86 machine (which Im on now), downloaded the Debian SPARC net install, and burned it to a CD. Put the CD in the Ultra 5, installation proceeded nicely, though with one disconcerting message stating the urgency of which a reboot was required (though still telling me to wait for installation to finish). I mean, the whole installation process basically went perfectly except that one odd message.
So, when install is complete, I choose finish installation, the machine reboots, ejects the CD, and then ultimately get a message saying "cant open boot device". I am very new to Sun hardware, and am by no means an expert to Linux. The only thing Ive really tried so far is to type "boot hda" which only causes the same message to appear.
From previous experience, I have written on paper the info for all of my partitions. So I think my Debian install is sitting there waiting to be utilized, but the Sun hardware is oblivious to the fact that theres a perfectly good OS on the machine yearning to be booted.

I'm inexperienced in Debian. I have a dual-boot machine (64-bit, Debian 7.3, Windows 7, legacy boot) and encouter a problem at boot ever since I completed the installation of Debian 7.3 alongside the exising Windows 7. This machine has six hard drives: two are intended for ntfs storage of general data (raided together by RAID1); two more are intended for ext4 storage of general data (also raided together by RAID1); the fifth contains the Windows OS files and the sixth contains the Debian OS files. The problem is that I arrive to the grub_rescue each time at boot, seeing the message:
GRUB loading.
Welcome to GRUB!
error: no such device: e081517b-3399-4067-9294-8f0686f753ca.
Entering rescue mode...

How to boot debian on an RK3288 based device (that isn't a chromebook?). Been trying to do so myself, but to no avail.
The closest match to my device is this one in the sense that it uses the same SoC - an RK3288. However my device is not a chromebook; instead it is called an "RKM MK902II". Unfortunately I cannot find any information on how to boot this device (it does have a micro sd card slot it can boot from, though I'm guessing it needs some sort of bootloader to be written onto a micro sd card in a specific way, but how!).
Interestingly the device I have is running some sort of version of ubuntu. Though how it boots it is an absolute mystery!
I've tried searching around on the 'net for a while now and apart from a script and a few "distros" distributed as image files, I can't really find anything at all. Looking for info about this device or RK3288 chipset?

I installed Debian Jessie (netinst, daily snapshot) on my Acer Aspire V5-123 laptop in the UEFI mode with the secure boot turned off. everything (network, hardware, partitioning, ...) went smoothly to the last step, but after removing the boot media (USB stick) and rebooting, the firmware could not find the boot device ! The only thing I can think of, is that the EFI boot is not set up properly by Debian installer, but I don't know how to fix it.

I've installed squeeze and wheezy on an old Toshiba Satellite 210 CS laptop with 48MB RAM and a 20GB IDE harddrive.Grub2 won't boot at all and stops with a "error: cannot allocate real mode pages". The solution to that is to use the grub-legacy package.The boot then fails with "waiting for root device" and drops to an initramfs shell.

I just compiled my first own kernel (I'm using Arch Linux), following the tutorial on the german site. Now I tried to boot it, I ended up failing with this message: Code: Waiting 10 seconds for device /dev/sda1 ... Root device '/dev/sda1' doesn't exist, Attempting to create it. ERROR: Unable to determine major/minor number of root device '/dev/sda1' Here is the important part of my menu.lst:
[Code]....
I simply copy&pasted the Arch-entry, i.e. I also had the disk by uuid there. The failure message was the same, just the root device name was the different name Also, at first I did not have the initrd line in my menu.lst (as written in my tutorial that I may not need it). In this case I had this error message:

Installed ubuntu 10.4 over previous ubuntu on Intel 945G. After installation and reboot the system does not boot: "no bootable device - insert boot disk and press any key".
Installation was done from USB-stick, prepared by UNETBOOTin. I have two HD's, one used for system + storage, another one just for storage. I manually deleted previous system partitions of previous ubuntu install in system HD. The system HD had about 1/3 of free and unallocated space for system partitions, which ubuntu installer created during the installation.
I tried to reinstall grub from bootable USB-stick and it succeeded but it did not help. The system is still not bootable.
I have used ubuntu for years and never happened something like this. Am I missing something or is ubuntu missing something???
HW failure is ofcourse possible but I am quite skeptical about it because Live ubuntu from USB-stick works well.

i had a working multi-boot system, vista on sda1,2; swap sda3; ext=sda4; ubuntu sda5; fedora sda6; data sda7 - i mount the data partition when using all of the linux releases so i don't have to have multiple copies of music, docs, etc. everything has worked fine until yesterday. i tried to install fc12 on sda6, replacing fc11. it required me to format sda6 as ext4. i wasn't sure where i had grub installed, but have a backup of menu.lst in data (sda7), so figured i could let it install to mbr or wherever it wanted to by default. when the install completed and i reboot, i get a black screen and these messages: CLIENT MAC ADDR: 00 19 XX XX XX GUID: XXXXX PXE-E53:
No boot filename received
PXE-M0F: Exiting Intel Boot Agent.
No bootable device -- insert boot disk and press any key I tried reinstalling fc12, same exact errors. I then thought maybe the problem had something to do with ext4 partition mixed in with ext3's, so i installed mepis on the sda6, and let it write grub to mbr (i think, not really sure where it wrote it). anyway, i still get the identical black screen. no grub type menu or anything. the screen used to show "DHCP for a few seconds", but doesn't anymore after i disconnected the ethernet cable.........

I want to be able to tell processes/programs somehow to use a specific nic. I have a laptop (used as dekstop) and want to make pidgin use my wireless. I have a gigabit wired connection and a wireless connection. I want to force pidgin to use the wireless connection. But more specifically, I just want to block pidgin from using eth0... how to go about that? I can't find anything that will block applications... I could block outside servers from communicating with eth0, but I don't want to do that.

Just completed installing Xubuntu 9.04 to my old Dell Latitude CPi and it seems to be working quite well. However I need to assign interface eth0 to my pcmcia network card (as opposed to eth1 or eth2). I have two cards to try out. One of them comes up as eth1 and the other as eth2. There is no eth0 listed when I run ifconfig -a. There is no built-in network cards on the laptop, so I don't know why it won't assign eth0 to either of the cards.
how to assign eth0 to either of the two PCMCIA network cards.

I'm trying to mount a USB key in a RHEL5 box to upload some file. I found doc online and followed it and mounted it fine the first time. Then I unplugged it and found that I have another file to upload so I plugged it back in. However this time it's not assigned a partition (last time was sdb1) and I can't mount it anymore. I think the USB key is recognized and the driver is installed properly:

This is a long shot but I'm looking for a way to assign an IP to a specific location or process. I'm running a server for a small indie game that I liked, I intend on running as many gameservers as possible from this server, however I hit a problem: The game limits servers to 4 per IP address, after this the servers no longer are able to connect to the main server and therefore be used. My server has enough IPs to run many gameservers, but I'm unable to work this out.
I need to assign either an IP address to a process or folder, right now I have it set up like so: (assuming 1.1.1.1 = server IP)
/gameservers/server1/program < assigned to 1.1.1.1
/gameservers/server2/program < assigned to 1.1.1.1
/gameservers/server3/program < assigned to 1.1.1.1
/gameservers/server4/program < assigned to 1.1.1.1
[Code]....
I do not have access to modifying the core program, it runs in Java. How would I go about doing this, if indeed possible? I need to either apply the selected IP to a folder or process without changing the actual program.

I am using linux mint and have installed Netbeans on it but whenever I run netbeans from accounts other than root it throws an error for not having permission to start glassfish server of netbeans. I also tried running this application using run as administrator option but then the application does not start.
So is there a way to assign netbeans admin rights permanently so that whenever I start this application from other accounts I should not face this error?

The goal was to remote desktop to my linux box from my windows machine, I went down the path of TightVNC. Installed and ran it.. thought I was all clear.. however the keyboard keystrokes are all jumbled, and seem to be all over the shop. (i.e.: when I press 'p' it actually comes out as 'X' etc. Happens for all keystrokes. Had a quick look around but haven't found any information on it. Uninstalled tightvnc server and installed vnc4server and it resolved the issue, shrug.

when I'm in my campus I saw things like this from tcpdump:
client-64-15.department.univ.edu
client-x-y.department.univ.edu
gw.nettokurabu.univ.edu
and my laptop got a name like that too (x and y being last 2 segments of the IP)out of curiosity, how to assign names like that to each IP? well, the names are not in dns records (can't resolve them to IPs)... when I set up (illegally) my on subnet with a routing software the addresses I used also already have their name without me configuring it before...

Using things like awk/sed, but have managed to cobble together what I needed so far without a problem. The only thing I'm struggling with is to assign the content of a particular line as a variable, and then to use it again throughout the file.
For example, if what I want is the first line of the file to become the variable "from1", and then to replace the word "Subject" in the file with the string "Message from [from1]". What I thought would work
I tried a few diff combinations but nothing seems to work. All I get is the terminal hanging indefinitely.
