How can I find all the devices(printers,etc...) and computers along with their OS if any installed that are connected in my intranet (devices/computers may be down here)?
I did this earlier using netstat or nmap not sure what I used and how I did.
I have a fairly simple iSCSI setup using two devices, but they have swapped names on different machines. running CentOs 5.3 ia64, and using iscsi-initiator-utils-6.2.0.868-0.18.el5
vm1:
[root@vm1 ~]# fdisk -l
Disk /dev/xvda: 4194 MB, 4194304000 bytes
255 heads, 63 sectors/track, 509 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
[Code].....
Any way to get iSCSI to mount the devices as consistent device names ?
Well, as many proxy applications, GNOME Network Proxy Preferences only allow to ignore hosts. What I want to do is exactly the opposite. I only want to use the proxy for few sites. Is it possible to define only the allowed hosts in any way?
PS: I know FoxyProxy add-on for Firefox does this, but 1)I don't use Firefox and 2)I want the proxy settings system wide not only for browser.
I've got three network devices on a laptop:
1. Built-in ethernet LAN
2. Built-in ethernet WLAN
3. PCMCIA ethernet LAN
I installed Ubuntu Server on this computer without the last one inserted.I inserted the last one today, and it lights up when i put in the cable. To be sure if Ubuntu has found it, I tested with the install CD and could see that it found all three at the first part of the installation where I have to chose a primary device.I can't get my WLAN card working, neither do I get my PCMCIA LAN card working. The third card, this PCMCIA card, has worked on Ubuntu Desktop using another laptop. And as said, the setup finds all three.
I'm trying to use ssh-keyscan to get some known_host file population going on, but I have a ton of hosts I want to scan, all with multiple aliases in /etc/hosts. Is there a way to use my current /etc/hosts file to do an ssh-keyscan instead of making a special list of hosts that (from what I've read) ssh-keyscan needs?
View 2 Replies View RelatedI'm running wubi on XP machine. Started out originally with 8.04, and gradually upgraded to 10.04. Recently, I was creating linux bootable USB drive, and put it in my system to see if it would work. After booting the LiveOS, and rebooting my machine, I know get the error Cannot find grldr in all devices when booting Ubuntu. I don't know what grldr is, but I assume it is the GRUB Loader.
Did booting the LiveOS screw with my MBR perhaps?
How can I fix this, and if not, is it possible to reinstall wubi, without losing anything of what I have now?
Not long ago I lost all sound, but I got it back eventually-the system wasnt snesing my usb speakers.
Now its stopped recognising them again and I cant remember how I got it back before.
How do I find a list of USB devices?
I'm installing 11.4 as a guest under Citrix's XenServer. The only access to a guest's graphical desktop is via VNC.The problem is that I can't achieve runlevel 5 as X can't find any devices. With 11.3 I was able to run Sax2 and add a dummy screen device to Xorg.conf that it created.When Sax2 was removed from 11.4, what was the fall-back for configuring X?

1. Where do I find my windows files when I am booted up in Ubuntu?
2. Where do I find and manage USB devices. My second monitor doesn't turn on in Ubuntu. It uses a USB attached device to connect.
There are probably some other things I should ask but am too new to know it.
I bought this bt dongle, and when i plug it, the operating system detects it and everything seems to be working fine. Although, When I search for devices, neither my phone nor my laptop are found. Searching for devices on both of them doesnt find this computer either. lsusb output is : Bus 002 Device 006: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)

How can i find through terminal that which devices are external and which are internal.
By external i mean devices attached to USB port. For Example, USB Drive, Portable USB HardDrive etc
By internal i mean devices attached internally. For Example, SATA Harddisk etc.

If I plug in a cheap USB adapter, I'm able to connect and use the devices.My computer is a HP ProBook 4330s running Debian Jessie. And as far as I can tell the Bluetooth adapter is a Ralink rt3592 combination Wi-Fi and Bluetooth PCI card. The Wi-Fi works fine, but when i try to connect to a Bluetooth device, I get no search results.

The intention is to have this system dual-boot. When i first put it together, i decided to setup a raid5 array spanning 3 sata drives. I installed Windows 7 first, decided i'd get to Linux later. I left 150mb or so at the beginning of the array for /boot, and about 200gb at the end for my linux install. i'm getting to the linux install. My distro of choice is Fedora 12. I start the setup, and at the point where it's time to partition, the installer tells me that its unable to find any suitable storage devices.
I Crtl-Alt-F2 to a console, and fdisk -l. Fdisk reports three individual drives which all have partitions already. All have free space. None make sense. So i turned to google, and found some threads which explain that this chip doesn't run a true raid, rather its what's been referred to as fake raid. Which is that it depends on the windows driver in order to actually present the array to the OS, and that the best way to get by that on linux, is to break the array, and use LVM instead.
That's all well and good, but i lose two things in doing that. First i lose the resiliency of raid 5, and second, well, what does that do to my windows install? I've considered moving all of my data from windows to other machines, and then just starting from scratch, but i'd really much prefer a method of using the chips fake raid in linux. Is there a driver, or module which i can install to make this happen?
Ubuntu is perfect for me, except that i have to dual boot sometimes to windows 7 for the one application that wont run in a virtual environment (LockDown Browser, and occasionally onenote). Except, i cant find tablet control features in Ubuntu, to change input devices (the touchscreen is awful, but I cant turn off the option to use finger as an input device. Also, when i boot to windows 7, the mouse track pad/left and right click doesn't work (they work in Ubuntu)? The keyboard does, and so does my stylus (which I have to use as a substitute)
