Dec 2, 2010A friend of mine is setting up infrastructure for a new call centre and they are using Ubuntu Linux on staff desktops. They need a chat program that will only work on the local network, and they want to allow staff to only access a browser, the chat client and spreadsheet software.
(a) What chat program can they use, and
(b) How can one disactivate most of the programs running on the desktop? Is uninstalling via synaptic/ Ubuntu Software Centre overkill?

Sep 23, 2009i wanted to capture the stdout and stdin of a child process within a parent so that any output of child is sent to the parent and any input taken from the parent. code is simple enough and i have followed all code guidlines on the internet (some guidlines do differ also) my select call either hangs if i do not give a tmeout and with a timeout it returns 0 descriptors to be written to or read from:

why select hangs without a timeout ... why can it not detect that the pipe is write ready i.e parent can write to it ... if it does not detect tha read pipe as having data...
Ubuntu :: Initramfs On One Of The Kernels?
Aug 28, 2010I am using Ubuntu 9.10 and am facing an issue while booting up. It goes into initfs command prompt on one of the 4 kernels that show up in the boot menu. I tried to look around for a likely solution and hence did the following:1. ran "chkdsk c: /f" in my windows partition.2. Added "rootdelay=90" in "/boot/grub/menu.lst" file.This is how my /boot/grub/menu.lst file looks and the problem is with the kernel 2.6.31-20-generic:
title Ubuntu 9.10, kernel 2.6.31-20-generic

Ubuntu :: Add Curl To Initramfs And A Script Which Uses It
Jun 20, 2010I am trying to learn how to modify the initramfs in a way which is so Ubuntu-friendly as possible. I do not just want to unpack it, change it and re-pack it, as my changes won't be kept when I upgrade my kernel next time.
What I want to do is: Add curl to the binaries available in the initramfs Add a script which is run after networking is set up which calls curl In case there is no "after networking" I have to setup networking myself using DHCP. There is a tiny client inside BusyBox if I am not mistaken. I have googled a lot to get this information. As well as looked trough more than a few books.

Ubuntu :: Update-initramfs From Another Machine?
Jan 24, 2011I'm finding myself in a situation where I am locked out of my machine (because of a initramfs that doesn't allow me to log in). I think I know where the problem is, but I do not know how to go about rebuilding an initrd file from another machine (especially since my second machine is running on a lower kernel version).
I have tried booting from a LiveCD, but that does not allow me to make any changes to /etc/update-initramfs/. Currently do not have a USB drive handy. How would one go about this?
Ubuntu :: Cannot Delete Partition Due To Initramfs?
Aug 6, 2011I am having trouble accessing my computer after abruptly shutting it down because it was booting off of a live CD and I just wanted it to boot of the HDD. When I try to boot up from the normal HDD I used to get a lot of errors about /dev/sda being not found, and then it went to an (initramfs) prompt, from which I could do pretty much nothing. I booted into a live CD, and basically I didn't need any of my data so I wanted to just get rid of the problem partition and reinstall. I attempted to delete the partition, but that didn't work, saying something about /dev/sda being busy (even though I had booted from a live CD and had not mounted the partition).
Anyhow, now when I try to boot from the HDD I get:
"Error: no such partition. grub rescue>"
Basically what I'm trying to do is just get rid of this partition and reinstall, but I keep getting errors about it being busy and not being able to delete the partition. Is there someone with a way to allow me to just blast this partition and reinstall? I've got a windows 7 partition on the same HDD and I'd really like to leave that one alone, but the ext4 and swap partition can just go.
Ubuntu :: Clean Up After Update-initramfs -u?
Jun 21, 2010I'm working on a custom Ubuntu 10.04 live cd, and I've found updating the Plymouth splash uses up a lot more disk space. The culprit seems to be the command update-initramfs -u, which is needed to apply the new splash image. I'm guessing it's making a new intrd image or something.

View 2 Replies View RelatedUbuntu :: Recover From Busybox / Initramfs 8.04 NTFS?
May 22, 2011I either installed Hardy heron or its predecessor by accident, but began running it exclusively. I did it way back when while trying to create a test drive disk, and I did not repartition the drive, because all my windoze NT stuff survived. I'm now 8.04. Yesterday I had a bunch of updates to do, did them, closed a ton of windows and then pulled up 3 open office files and each, when it came up said there wasn't enough space to save all needed information as they opened. I then closed them and one hung and froze the whole machine, leading me to do a reset. This is BEFORE rebooting from the updates.
Now when I boot into Ubuntu (I'm dual boot) I start to get the opening Ubuntu GUI screen but then get :
BusyBox V1.1.3 (Debian 1.1.1.3-5ubuntu12)built in shell (ash) line followed by:
initramfs)
I'm essentially a total noob, I've rarely used command line and not for a long time. I made a version 11.04 live disk, and it says that the file system is clean, but will not show me any of my old files, only the NT files and directories. I have a ton of unbacked up important data in Hardy Heron so I don't want to do an install from the 11.04 CD.
I've read several threads so far, and can't seem to find anything addressing this that I understand. The drive is a 160GB drive on an HP Pavilion dual core that has a 154GB NTFS boot partition, which is where I'm sure the Hardy Heron files are, and a 6GB FAT32 HP_RECOVERY partition that windoze lists ad drive D (the NTFS is C) The live disk says the FAT32 partition is /dev/sda1 and the NTFS is /dev/sda2
Where should I start? I've seen stuff about booting into recovery mode, but that isn't an option when I boot from the hard drive, and the only older ubuntu disk I have is for 7.something and generates "defective CD" type error messages.

Ubuntu Security :: Prevent Kernel Initramfs Extraction?
Jul 16, 2010I'm writing here because it's mainly a security issue even though it's rather kernel related.
I'm compiling my own vanilla kernel with an initramfs included in the bzImage. That image contains encryption keys for the rest of the system. Even though it's not for everybody the initramfs image can be extracted from the kernel, decompressed and the keys extracted.
I'm looking on a way to prevent this.

Jan 22, 2010unable to install initramfs-tools error in Karmic I'm having a devilish time installing Karmic on my AMD 64-bit.
Today's missive is:
"Unable to install initramfs-tools."
"Check /var/log/syslog"
After a trying to fix a corrupted 9.04, I have attempted repeated installs of 9.10 on a completely reformatted clean drive. I can get the live CD working, but when I try the permanent install, using the guided full drive install, it stopped at "Unable to install initramfs-tools." and halts the base system install. I can't find anything on this for Karmic and Launchpad says it was superseded.
Can I skip this and go on? It showed a install list going forward, but if I can't put in the base system, how do I proceed? I've burned 2 9.10 disks, a new 9.04 disk, downloaded 9.10 via package manager while in Live CD and get errors on all during the install process. the check sums match on D/L, but I can't figure how to do a chksum after it's burned to disk. The file sizes do match, but when I go for the install something always halts it at different steps with different errors. No joy.
Ubuntu Installation :: Server Won't Start Properly - Goes To Initramfs Prompt
May 31, 2010I'm trying to install ubuntu-10.04-server-i386 in Virtualbox on Windows XP Home (for use as a Drupal development server) using the instructions here [URL]... the Ubuntu server will not start properly. Instead it goes to an initramfs prompt as follows
[code]...
Another thread suggested typing 'exit' after a while but it just repeats the same output. It seems the root disk doesn't exist. I allowed the installer to set up partitions to its own recommendation (Guided?) although I'm not entirely sure what it did - I think there are two partitions but you guys will know that. The host disk is SATA. The CPU is a dualcore but I've only enabled one CPU on the guest within Virtualbox. Also, I had to enable PAE mode as without it Virtualbox crashed every time I started the guest. PAE wasn't mentioned in the instructions mentioned above. I've tried changing the various other disk parameters in Virtualbox (without fully understanding them) but no luck. I also ran run the boot info script from a desktop LiveCD and the results are given below.
