In common with other parts of the early Unix operating system, the term 'daemon' gives little away about what its function might be. A daemon is a task that runs in the background, and there's a small army of them that are started when you fire up your machine. There are daemons for controlling automated tasks, daemons for managing power and CPU use, daemons for printing and daemons for writing the system logs. Build a centralized log management and monitoring system. Seasoned system administrators know that routinely reading system logs is an important task, but reading endless lines from logs is both time-consuming and boring, especially if you are responsible for a large number of busy servers.
In this article I will show you how to set up a system that gathers and archives system logs from many network hosts and emails only important or irregular system events to administrators. The majority of GNU/Linux distributions uses the good old syslogd system logger by default, which is based on the original 4.3BSD syslogd daemon. Syslogd is a fine system logger, but it lacks some advanced features modern alternatives offer. We will use syslog-ng instead, which provides all the functionality of the traditional syslogd along with some nice enhancements. Among others, it provides powerful filtering capabilities based on message content, and can also be used in a firewalled environment without problems.
DeveloperWorks : Linux Professional Institute (LPI) exam prep. Limiting Linux Logins. I'm sometimes surprised at the complex solutions administrators come up with to keep out users whenever that course becomes necessary when a simple, built-in solution to their problem already exists.
In this article, we'll look at a few different mechanisms used to keep out intruders either temporarily, or on a more permanent basis. Most obviously, Linux offers single user mode, in which only the system administrator can log on. You can get to single user mode in a number of ways. Typing init 1 at a shell prompt as root will do it nicely, and do it immediately. As per the shutdown man page, if you don't explicitly tell the command to halt or reboot (using the -h or -r flags, respectively), it'll put you into single user mode.
The other way to get into single user mode is at boot time, either by having a GRUB entry for single user mode, or by editing the GRUB "kernel" line at boot time. More permanent lockouts. Excellent Adventures with Redhat 7.3 on a Thinkpad 600 Laptop. Workbench Linux distro is a workhorse for software developers. By Mayank Sharma on September 18, 2008 (9:00:00 AM) Workbench is based on Xubuntu, the Xfce-powered Ubuntu flavor, but unlike Xubuntu it doesn't fit on a standard 700MB CD.

For those "oops" moments: ext3undel. By Kurt Edelbrock on July 10, 2008 (4:00:00 PM) Files on the ext3 filesystem have two parts.
The file's metadata -- that is, the file name, size, and creation and access dates -- is stored in a Unix data structure called an inode. The actual file data is stored in blocks on the hard drive. Deleting a file destroys the link between the metadata and the filesystem blocks, eliminating the association between the file's information and content. Both the inodes and the data blocks are marked as free, and the operating system will use them to write new data when it needs to. Centralized Syslog Server Using syslog-NG with web Interface using php-syslog-ng.

Reincarnating a discarded laptop with Linux. By Howard Fosdick (Aug. 1, 2006) I recently picked up an old discarded laptop... straight out of a corporate garbage bin, as a matter of fact. Could it be useful? What could it do? As an IT professional, I thought I'd find out. Rebooting the Magic Way. If you have ever had a hard drive fail on a remote server you may remember the feeling you had after trying to issue the following commands: # reboot bash: /sbin/reboot: Input/output error # shutdown -r now bash: /sbin/shutdown: Input/output error Obviously, there is a problem with your drive.
These commands are failing because the kernel is unable to load the /sbin/reboot and /sbin/shutdown binaries from the disk so that it can execute them. A fsck on the next boot might be able to correct whatever is wrong with the disk, but first you need to get the system to reboot. Rotating Linux Log Files.
