General :: Figuring Out \ Run These Commands On Boot?
May 24, 2010
I just started learning how to manipulate Linux (Debian Lenny) about a month ago with the intention of ditching Windows eventually and learning to configure serversn the process. But, I still need Windows for certain things. I downloaded and installed VirtualBox (I know, VMWare is better, but I didn't know that at the time and don't want to go through the process all over again) and got Windows XP working with a tap interface and bridge interface to get the guest OS to talk to the home OS and connect to the Internet.
My only problem is that the tap interface and bridge interface disappear when I reboot and then I have to issue the commands to set them up all over again. I know there is a way to write a script to run on boot to create them and bring them up, but my whole technical career has been with CLI-based stuff, not scripting. I'd like to eventually learn it, but I'm a learn-by-doing type. Basically I need the following commandsto be implemented at startup:
sudo tunctl -t tap1 -u allen
sudo brctl addbr br0
sudo ifconfig eth0 0.0.0.0 promisc
[code]...

I downloaded rhel 5.5 CD 1 iso to my PC, and used it as a virtual CD-ROM to kickstart HP DL380 G4.Here is my questions:
1. how can I cut and paste boot commands (very long strings) from my PC to iLO remote console?
2. is there anyway I can get "boot prompt" by ssh to iLo's IP?
3. after kickstart, I want to eject the virtual CD-ROM / media, I have tried the following method in the kickstart profile, but all failed, after reboot, it still boot from the virtual CD-ROM. So how can I reject the virtual CD-ROM for rhel 5.5 kickstart?

I'm trying to follow a few commands that have been recommended to to get my system to boot again .
The following are the commands:
Code:
Then modify the first command I gave you to read:
Code:
All other commands should work:
Code:
At the end, you should also run the following commands:
Code:
And here is the terminal readout from the first few commands:
Code:
Am I right that at this point I should issue the " -f " command or should I issue the -f at the end of the last command?

I have a server in which I'm trying to install Debian into. There's no BIOS, only EFI boot. The vendor locked it down so there's no way to see it or get into it.
The Wheezy 7.8 netinst CD has EFI boot parameters and works on everything I throw it in, except this one server. Booting it up, the code doesn't see the EFI and boots into normal mode, negating every chance to install it (dozens upon dozens of failed installs).
During boot, I press the [TAB] at the Debian Linux installer menu and get the load parameters (/install.amd/vmlinuz vga=788 etc). What parameter can I add to this line to get it to run in UEFI mode so we can install it?

I have openSUSE 11.2 and boot using GRUB. I was looking on start-up options for 11.2 and saw where it said
splash=silent
and
quiet showopts
I was wondering what they meant?

I want to turn off CPU throttling, and I notice how each time opensuse boots up, it imposes it.
I would like to know where it does this. I suspect - but actually I don't really know - if it's the HAL daemon that does this. Could be.
In any case, rather than have to key it in each time, I put the relevant commands (cpufreq-set) in boot.local. No effect.
I suspect boot.local might not be the best place for such a heavy duty command like this one.
Are there any there places I could put it so that it executes automatically?

#sudo modprobe lib80211

I have done these commands as per the readme included with the source files.
# load driver as described above
# cp wl.ko /lib/modules/`uname -r`/kernel/drivers/net/wireless

I didn't change anything; it just stopped working on boot. I've changed permissions according to messages from log files. No good.I now get messages saying "unable to open display ' '." If I set the display (I've done this several ways, the messages say "unable to open display ':0'."
Systemd is taking control of everything basic, with almost no documentation and no configuration tools at all: rationalization by lunatics.You can make a script to run commands on boot using systemd on Jessie by creating two files: the script, in any location a file in /etc/systemd/system that runs that script..My script is called james-boot.service, placed in my /home/james/.bin directory.
#! /bin/sh
# this is run by /etc/systemd/system/james-boot.service
# Enable with sudo systemctl enable james-boot.service
# Check with sudo systemctl status james-boot.service
# If it says the service is loaded, it's OK -- inactive only means it's done running.
[code]....
This file must have ownership root.root, with (apparently) permissions 664 (rw-rw-r--).After creating, enable with sudo systemctl enable james-boot. service.Check with sudo systemctl status james-boot.service. If it says the service is loaded, it's OK -- "inactive" only means it's done running.

Does any one know what this can be and how to solve it?

I've got myself the curious situation where, when I boot the system, I can get grub to start, but it always drops to the prompt.
I can run:configfile /grub/menu.lst
and this brings up the menu with no problems, and from there I can boot the system to either linux or windows. What I don't understand is why it wont go to the menu in the first place?As far as I can tell, grub/Kubuntu got confused when installing, as each of the hd#,# settings in the menu.lst have needed tweaking to let the system boot. (e.g. windows is actually hd0, but the original install had it at hd2. Likewise linux is on hd1, but the menu.lst had it at hd0). I've happily tweaked these to make the system boot, but would appreciate any help in convincing grub to actually load the menu without me having to use the prompt.

I started another thread about this to get help booting into openSUSE after Fedora rewrote my bootloader and deleted all other entries. I managed to fix it but I never did find out why the following commands caused my system to boot to the grub shell instead of the grub menu.
Code:
grub
root (hd0,3)
setup (hd0)
quit
reboot
Can anyone explain to me why these commands caused my system to boot directly to a grub shell? It's as if there were no /boot/grub/menu.lst files for it to use, but after I got everything back to normal, the files were still there.
If it helps, this is how the drive was setup before and now, except Fedora was on /dev/sda4 and has since been deleted.
Code:
Device Boot Start End Blocks Id System
/dev/sda1 1 262 2104483+ 82 Linux swap / Solaris
/dev/sda2 263 13316 104856255 83 Linux
/dev/sda3 * 13317 14621 10482412+ 83 Linux

Use the following information in your script. Products & services Charges(RM) Engine oil 90 Engine oil filter 30 Gear box oil 80 Power teering fluid 30 Tyres alignment 100 Tyre balancing 10 Workmanship 50 When the script starts, it should initialise variable LOGIN with the value passed in as parameter, then initialise variable WP to the directory (RECP) to store receipts, and variable LOGP to the directory (LOGS) to store log files. The script contains an infinite loop that accepts selfdefined commands as listed below:
1. genp
2. reprint
3. log
4. price
5. bkup
6. !help
7. quit
1. genp
Generates receipt and then displays it on screen. User should input quantity of all products. Initialise the quantity of each product at the beginning of script.....

I'm having problems with Common Shell Environment Variables. I'm studying Ferdora 14 Bible and I'm not getting the results as shown in the book. Please take a look at what I'm doing and let me know where I'm going wrong.
As you can see I start out as a User by the $ prompt, according to the book I should get the following information: /bin/bash. As you can see I get nothing, so I entered into SU mode and ran the same command and still I get no information,
This isn't the only variable I'm having problems with.
Have I done something wrong code...

I just started having some problem after switching my desktop manager from GNome to KDE. One of such situation is the konsole on KDE not running popular commands like ifconfig that I run when I was using GNome.
Although, I have fallen in love with KDE, I am feeling a little bereaved of some feature. where I could use KDE to mastery? (Because I want to believe that I am not doing somethings I should and not that KDE is so limited)

i am still a linux newbie. i'm trying to study the features of the different LINUX distros through installing ubuntu,debian,redhat,centos and fedora as Virtual Machines in VirtualBox.As i've figured out, they look different somehow, they have diffirent managers ,i.e. for downloading or updating their components. BUT MY QUESTION: are these distros internally compatible ?
Do any commands exist in one distro but not in the others? ARE ALL Distros compatible on the CLI-basis ?
