The Linux /proc Filesystem as a Programmers' Tool

Post date: June 22, 2005, 09:06 Category: Programming Views: 3409 Comments
Tutorial quote: My entry into systems programming was guided by my desire to understand further the operating systems I was working with daily as a contract UNIX and, later, Linux system administrator. The result of this was ifchk, a packet sniffer detector I wrote in C and released in June of 2003. ifchk initially was written under IRIX and then ported to Linux, mostly under the 2.4 kernel. The current ifchk revision, beta 4, recently was released and beta 5 is on the way.

My work on ifchk has allowed me to examine programmatically several areas of operating system functionality. Examples include the Linux netlink(7) and rtnetlink(7) facilities, device control--that is, network interfaces--via ioctl(2), signals and proc, the process filesystem. Proc and its ability to display a wide array of data concerning the runtime state of a system are the focus of our discussion here.

The lost art of named pipes

Post date: April 15, 2005, 21:04 Category: System Views: 2840 Comments
Tutorial quote: A "named pipe" -- also known as a FIFO (First In, First Out) or just fifo -- is an inter-process communication mechanism that makes use of the filesystem to allow two processes to communicate with each other. In particular, it allows one of these to open one end of the pipe as a reader, and the other to open it as a writer. Let's take a look at the FIFO and how you can use it.

Benchmarking Maildir Delivery on Linux Filesystems

Post date: April 12, 2005, 07:04 Category: Benchmarks Views: 3048 Comments
Tutorial quote: The goal of this set of benchmarks is to determine which of the leading Linux filesystems (ext2, ext3, ReiserFS, and XFS) offer the best performance when used for accepting maildir deliveries. The resulting system should be a good balance of delivery and retrieval performance under potentially high concurrent filesystem load.

Post date: May 6, 2010, 11:05 Category: Installing Views: 4455 Comments
Tutorial quote: Nexenta is a project developing a debian user-land for the OpenSolaris kernel.

In the resulting setup every user can have his/her own home directory accessible via the SMB protocol or NFS with read-/write access.
