Software :: Execute A Program As The Very Last Step Of Boot Process?
Feb 2, 2011
I want to execute a program at the very last step of Linux boot process. For Debian based Linux distro that uses BSD boot process, I came up with 2 solutions:
1) I should somehow call my program from the /etc/rc.local script (although is this the last step of the boot process?)
2) Use the "multi_end" and "sysinit_end" hooks for executing it at the end of rc.multi rc.sysinit respectively (I don't know how to do it though).

I'm building a Cluster with 20 small Compaq ipaq PC's as the nodes. I have absolutely no room for any keyboards on this cluster. The PC's require a keyboard to boot, and there are no BIOS settings I can adjust to fix this problem, and no BIOS updates. I have found a small DOS .com program by Compaq called NO_F1.com it's designed to allow the computer to continue to boot without a keyboard. it's only 172 bytes in size. It sets a bit in the CMOS which allows the boot process to continue without a keyboard. It does not permanently set anything, so it needs to run each time the computer starts.
Is there any way I can execute this program very early in the boot process every time the node boots ? I thought about dissembling the program and trying to modify the boot loader, or some other ASM program, the program is only 172 bytes. But thats really over my head. What could I try, I don't know what to do. Also, I have no floppy drive and no CD drive to boot from, only USB or hard drive.

My son's desktop has Fedora 12 and a wireless card. Everything worked for a long time until one fine day the network management just disappeared from both System/Preferences menu and the panel on top.I can run a Live CD with Fedora 12 on that machine and it immediately connects to our home wireless network. Booting from hard drive has no sign of NM. Trying to run 'yum install NetworkManager-gnome' does nothing because there is no connection. Running the same command as a LiveUser from CD does seem to install everything (but where to???), no errors reported, and still the is no network functionality upon reboot from the hard drive, even when plugging to LAN with a cable.It seems that I need NetworkManager in order to go online in order to install NetworkManager.I have other computers at home that work fine, I was able to download a couple of archives with NM, but I am new to Linux and have no idea what to do with those files.I could not find any step-by-step installation guides for NM, especially when the computer has no connection at all.

Recent refugee from Ubuntu here. Fedora fan for one month.I have two computers that access the Internet through a router. They are assigned IPs dynamically by the router's DHCP. I need each computer to be able to "see" some shared folder on the other one, with RW permissions to that folder and its content.I want to use Nautilus to access those folders from each computer.
Tried NFS, Samba, gnome-user-share to no avail.
Willing to kill Fedora's firewall forever in order to ease folder sharing.Can some kind and knowledgeable person try a step by step setup guide for this? As an 8-year Linux user I am not afraid of command line interfaces.

I have a file with two fields of numbers that I want to use as input for another program.
Code:
The above code does not work, as I think it would take the whole first and second fields as the input for one particular instance of the program 'inputbashangle'. What I want is to get the first two numbers from the first line of the file 'outfailtest', execute 'inputbashangle' with them, then move on to the first two numbers of the second line for all the lines of 'outfailtest'.

I have read a bajillion tutorials and have gotten nowhere. This is my first Linux box, and it has been nothing but headaches. i'm pretty handy around computers, I took a Unix class, and I used Dos as a kid, but i'm just having so much trouble with this.I just want to remotely control my Ubuntu box from my windows laptop over my home network. That's it. I cannot find one comprehensive step-by-step tutorial that will show me how to do this. Everything I find assumes I know at least something about linux, and I don't.
I have Putty, realvnc and tightvnc viewer installed on my laptop.I have open-ssh and vx11 somethingorotherinstalled on the Ubuntu box. I have also allowed remote connections on Ubuntu from system>preferences. I am getting very frustrated and would really appreciate someone giving me some help. So far I HAVE been able to remotely control the box through one method. Through the GUI on ubuntu I went to: System>Preferences>network connections
and set the server to static IP, then I was able to use real VNC viewer from my windows machine to connect to the IP I set (192.168.0.11) but I couldn't get there through servername.local or whatever it said. The problem witht his solution is that the Ubuntu box then couldn't connect to the internet (which I need it to do.) someone please please please direct me to the information I need for this simple task. I just need to remotely control the desktop, the reason I wanted to use vnc through ssh so that I can leave the ubuntu box headless. Using just VNC I was having problems when the box was rebooted (had to log in before I could remotely control it... something about a security key ring?)

Currently, I am setting up multi seat system with Fedora 14 but after hours of searching, i'm still running into some issues. I have managed to edit and get the xorg.conf file working although im still having problems.
I want to set up the multi seat so that 1 server with 2 graphics hards connects to two monitors and have their own sessions. I have got the xsessions working although you can move the mouse across 1 screen to the other. Is there any resources as to step by step for setting up multiseat of fedora 14? Are there any main issues regarding custom.conf?

I have a game server running using java, and it tends to crash sometimes, and only way to start it now is manually, so i thought i could create a script to check periodically if java is running, and if it isn't, run my startup script for the game server also, if it's possible it should log when it actually started the server startup script into a text file or something, so i can check why it crashed.

I've just installed subversion.I need to create a script /etc/init.d/svnserve that will start at boot time.I want to use start-stop-daemon --start so I can track my process and eventually kill it using start-stop-daemon --stop.My problem is that I can't get it to work and the documentation shows no exemple.
I've replaced $DAEMON by the whole line: svnserve -d -R -r $REPO_ROOT and got -d is not an option.I'm not quite sure what to do at that point. If someone has some experience with start-stop-daemon it would be great.
