Setting up a serial console
Author: Daniel15 • Tags: linux • Comments: 7Setting up a serial console This tutorial will show you how to set up a serial console on a Linux system, and connect to it via a null modem cable. This is quite useful if your Linux server is in a headless configuration (no keyboard or monitor), as it allows you to easily get a console on the system if there are any problems with it (especially network problems, when SSH is not available). In the end, the GRUB menu will appear over the serial link, as will the bootup messages (output when booting the system). I'm using Debian Etch on the server and Ubuntu Edgy on my client, although this should work on any Linux distribution.

Install and Configure Auth Shadow on Debian/Ubuntu
Author: Thanatos • Tags: apache, debian, linux, security, ubuntu • Comments: 3Install and Configure Auth Shadow on Debian/Ubuntu Auth Shadow or mod-auth-shadow is a module for apache (and apache2, sort of) that enables authentication against /etc/shadow. The benefits being that any system user with a password can be authenticated for web_dav, subversion or simply an https server. The only other way to do this is with PAM. That method is dangerous because the apache user (www-data in my case) must be able to read /etc/shadow. Obviously, not a good idea. Auth Shadow accomplishes this safely by using a intermediate program called validate. This works because validate can be owned by root but executable by everyone. In the event that your server is compromised through apache, your password file will not be readable.

Comments: 3 Either with chkrootkit or with rkhunter. chkrootkit Either install the package that comes with your distribution (on Debian you would run apt-get install chkrootkit ), or download the sources from www.chkrootkit.org and install manually: wget --passive-ftp ftp://ftp.pangeia.com.br/pub/seg/pac/chkrootkit.tar.gz tar xvfz chkrootkit.tar.gz cd chkrootkit-<version>/ make sense Afterwards, you can move the chkrootkit directory somewhere else, e.g. /usr/local/chkrootkit:
