Version control is the art of managing changes to information. It has long been a critical tool for programmers, who typically spend their time making small changes to software and then undoing those changes the next day. But the usefulness of version control software extends far beyond the bounds of the software development world. Anywhere you can find people using computers to manage information that changes often, there is room for version control

kfsmd is an interesting tool to keep track of changes in your filesystems. This tool based upon inotify which is a Linux kernel subsystem that provides file system event notification. Useful for file auditing. Applications can ask the Linux kernel to report changes to selected files and directories. I created the Kernel Filesystem Monitoring Daemon [...]

Root login is perhaps one of the very few vulnerabilities that Linux operating system faces. A person can hack into your system as a root user easily and can play with security settings. This guide will show you how to disable it so you can still login as root but just not directly, reducing the [...]

The process for managing local users and groups is straight forward and differs very little from most other GNU/Linux operating systems. Ubuntu and other Debian based distributions, encourage the use of the “adduser” package for account management. To add a user account, use the following syntax, and follow the prompts to give the account a [...]

Subversion depends on a number of third party tools and libraries.Some of them are only required to run a Subversion server; others are necessary just for a Subversion client. This section explains what other tools and libraries will be required so that Subversion can be built with the set of features you want

Lots of programmers like PHP for its ability to code and develop web applications fast. Code-debugging is a lot easier than with PERL or C. However, there is one thing a lot of developers are puzzled about, “How to run PHP Scripts with crontab?†Cron is normally available on all Unix and Linux distributions; if [...]

This says that we have NFS versions 2 and 3, rpc.statd version 1, network lock manager (the service name for rpc.lockd) versions 1, 3, and 4. There are also different service listings depending on whether NFS is travelling over TCP or UDP. Linux systems use UDP by default unless TCP is explicitly requested; however other OSes such as Solaris default to TCP.

In retrospect this was surprising (since we had not requested any DNS software during the FC2 installation procedure – FC2 install was kind enough to do it anyway) and perhaps we should have removed this version before installing since we ended up with -in our view – an incomplete installation. We may have had a complete install if we had done this – maybe not. We issued the following command to upgrade the installation:

Let say you are on an expensive satellite link that can barely provide enough bandwidth for your company’s Internet Access and you will want to do whatever you can to get as much as possible out of this link.

Most Linux distributions ship with tcp_wrappers “wrapping” all your TCP services. A tcp_wrapper (known as /usr/sbin/tcpd) is invoked from/sbin/inetd instead of the real service, such as telnet or ftp. tcpd then checks the host that is requesting the service and either executes the real server or denies access from that host. tcpd allows you to restrict access to your tcp services. You should make [...]

It’s never happened to me, but I’m sure it’s happened to others. The root password is gone. Forgotten. Changed maliciously. Mysteriously gone. The Linux Gazette has a great article on the three most common ways to deal with this situation. It’s important to note that there’s no way to actually recover the password, but you can change [...]
