Linux Sysadmin Basics -- 6.1 Process Signals
In this video I take a look at Linux inter-process communication using signals. We'll take a look at the interplay between the kernel and processes (and sometimes the user). Believe it or not, you can learn the basics pretty quickly and get some insights that are useful in the daily life of a Sysadmin. Some commands we cover in the process (hurr hurr): -kill (sending signals) -killall -pgrep -pkill

An Introduction to Linux IPC Facilities
Presenter(s): Michael Kerrisk URL: http://lca2013.linux.org.au/schedule/30020/view_talk Pipes, FIFOs, signals, datagram and stream sockets (and sockets in the Unix versus Internet domains), file locks (various kinds!), environment variables, memory mappings, event file descriptors (eventfd), pseudo-terminals, message queues, semaphores, shared memory, and good old regular files... The range of interprocess communication and synchronization (often referred to collectively as IPC) facilities available on Linux can at first seem bewildering. Which facilities should an application use? This tutorial provides an overview of each of the IPC facilities, showing the features that the different facilities have in common, and the features that distinguish them. The aims of this tutorial are to provide developers with examples of the use of each of the IPC facilities and the beginnings of a roadmap to help decide which IPC facilities are likely to be most suitable when writing new applications. I'll compare different IPC facilities using measures such as portability, flexibility, ease of use, operational limits, configurability, persistence (lifetime), access control, integration with the traditional Unix "everything is a file" model and the UNIX/Linux API in general, and specific functional advantages and disadvantages. I'll also briefly consider whether one can make any general statements about relative performance of different IPC facilities. Although aimed primarily at developers, other participants (e.g., system administrators) may find the tutorial useful for gaining greater insight into the operation, configuration, and management of the various IPC facilities. A reading knowledge of C will be useful. http://lca2013.linux.org.au/ - http://www.linux.org.au CC BY-SA - http://creativecommons.org/licenses/by-sa/4.0/legalcode.txt

C Programming in Linux Tutorial #084 - poll() function
C Programming in Linux Tutorial using GCC compiler. Tutorial should also be applicable in C/UNIX programming. An example on how to use the poll() function, an alternative to select() function, to create a timeout for the read() function. One of its uses is in TCP/IP socket communication where the server or client timeout when the other party does not send any data or acknowledgement. The example reads an input from the user, and times out if no user input for a period of time.

Undestanding basics of Zombie process with example : Advanced Linux Programming # Tutorial - 7
when a child process dies and has not been wait on, it will usually show up in a ps listing as "defunct". It will remain this way until the parent waits on it, when the parent dies before it wait()s for the child (assuming it is not ignoring SIGCHLD), the child is reparented to the init process (PID 1). This is not a problem if the child is still living well and under control. However, if the child is already defunct, we're in a bit of a bind. See, the original parent can no longer wait(), since it's dead.

HakTip - Linux Terminal 101: Controlling Processes
This week we are controlling the processes that we learned about last week. Last week we discussed processes- what they are and how to view them. Now, let's control those. Let's open the program called gedit- a text editing program. You'll notice your shell prompt will not return until the program is closed. Press CTRL-C to interrupt the program (or terminate). This works for most command-line programs but not all. Now run gedit again with an & at the end. This says we started job number 1, with a PID of 3853. Running ps shows the proccess as well. If you type jobs, this will also show you that gedit is running. (one job, number 1, command gedit &). To return the process to the foreground from the terminal, type jobs to find the number, then fg %1. To terminate again, press CTRL-C. Type CTRL-Z to completely stop a process. So if gedit is running, then type CTRL-Z to stop or pause it. You can restore the program with fg, or move it to the background with bg (bg %1). The number is optional if you only have one job running. Opening a graphical program may be essential if opening it in the GUI doesn't work or it's not listed in the window manager's menus. Do you want to completely kill the process? To do so, first type gedit &, get the PID, then type kill 3651. This will terminate the process. kill sends a signal to the process to terminate. When the terminal sees these keystrokes, it can send a signal to the process to do something. kill can have specified signals attached to it such as HUP for hang up (old school for computers that were online with phone lines), INT for interrupt (same as CTRL-C), TERM for terminate, STOP for stopping the process without terminating, CONT to continue after stopping, just to name a few. You can type kill -1 1234 to hang up, or type kill -INT 1234 to interrupt it. Use kill -l for a complete listing of signals you can send. Last but not least, you can send a signal to multiple processes. Type gedit & a couple of times for several instances of the program, then type killall gedit to kill all of the gedit instances. You must have user priveledges to send signals to processes that don't belong to you. To give you an idea of some other common processes, take a look at these commands: pstree (parent-child relationships of processes), vmstat (system resource usage), xload (system load graph) and tload (terminal graph). How do you control processes? There are other options out there. Make sure to email me [email protected] with your thoughts. And be sure to check out our sister show, http://www.hak5.org for more great stuff just like this. I'll be there, reminding you to trust your technolust.
